Description

Advanced gripping device

Technical Field

The present invention relates to tools for loosening and tightening fasteners, such as screws and nuts, and more particularly to a non-slip multi-directional driver head that prevents the driver head from damaging/abrading the fastener or slipping off the fastener during removal or tightening of the fastener.

Background

Hexagonal bolts, nuts, screws, and other similar threaded fasteners secure a plurality of parts together by engaging complementary threads (commonly referred to as female threads). The structure of such fasteners generally comprises: a cylindrical shaft portion having external threads, and a head portion at the trailing end of the shaft portion. The external thread engages with a complementary female thread, typically formed by tapping into a hole or nut, to secure the fastener and simultaneously the associated parts. The fastener is rotated or driven into the female thread by the head receiving an external torque force. The head is shaped to allow an external tool, such as a wrench, to apply torque to the fastener to rotate the fastener to engage the complementary female threads to some extent. Such fasteners are simple, inexpensive, and very effective and are therefore commonly used in modern society.

One of the common problems with the use of such fasteners is: whether the fastener is male or female, the tool often slides over the head. The reasons for this are likely to be: tool or fastener wear, tool or fastener rust, excessive fastener torquing, head damage of the fastener.

Disclosure of Invention

The present invention relates to a screwdriver head design capable of substantially eliminating sliding. The design of the present invention comprises several parts. The overall action of such portions may engage the head of the fastener, thereby effectively transferring torque between the driver bit and the fastener head. Conventional bolt drivers may use tools and bores that are not otherwise needed. The present invention avoids these problems. With the development of power screwdrivers and drills, it has become common to use power tools to apply torque to remove fasteners. The present invention provides a single or double ended driver bit that can apply a torque to a fastener clockwise or counterclockwise to lock or unlock the fastener. Most driver bits have a standard one-quarter inch hex grip end and include, but are not limited to, square, hex, or star shaped drive ends.

Detailed Description

First, it is specifically described that: the drawings used in the present specification are only for the purpose of illustrating certain embodiments of the invention and the scope of the invention is not limited by the drawings.

The present invention relates to a tool attachment, and more particularly to a multi-grip screwdriver bit, which is a screwdriver bit or a screw driver bit. The present invention can apply a greater torque to the fastener than other similarly sized conventional screwdriver bits without damaging the fastener head or the tool. The effect of the invention is achieved by the engagement structure having a plurality of features which enable the engagement structure to effectively grip the head of the fastener. The present invention is a screwdriver bit compatible with a variety of torque tools, including: conventional electric drills, screwdrivers, socket wrenches, socket drivers that can receive a driver bit, but these torque tools are not limited to the torque tools described above.

Referring to fig. 1, a simplified embodiment of the present invention is shown. In this embodiment, the present invention at least comprises: at least one screwdriver bit body 1, and one attachment body 19. The screwdriver bit body 1 is a stem which can be combined with a socket fastener, for example: socket screw and socket screw to quickly apply a torque to a socket fastener. The screwdriver bit body 1 further comprises: a plurality of side walls 2, a first base 14, a second base 15, and at least one bonding pocket 8. At least one engagement cavity 8 is recessed into at least one screwdriver bit body 1 from the lateral direction, thus helping to distribute the applied torque in the preferred application of the present invention to maximize efficiency and minimize wear. Generally, the screwdriver bit body 1 is a prismatic body composed of a high strength metal. The plurality of side walls 2 engage and grip the socket fastener to effectively transfer torque from the torque tool to the socket fastener. The first base surface 14 and the second base surface 15 are opposed to each other across the plurality of side walls 2; preferably, the first base surface 14 and the second base surface 15 are perpendicular to the plurality of side walls 2 to form the prismatic screwdriver bit body 1. In a preferred embodiment of the present invention, the first base surface 14 further comprises a first base surface 26, wherein the first base surface 26 is planar and perpendicular to the side surface 5 of each of the plurality of side walls 2. The side 5 further comprises a first portion 33. The first portion 33 is a portion of the side surface 5 along a first distance 21 to a position near the first side edge 3. The attachment body 19 allows the present invention to be attached to an external torque tool whereby torque can be applied to the socket fastener via the screwdriver bit body 1. The attachment body 19 is distributed along one rotation axis 16 of the screwdriver bit body 1 and surrounds the rotation axis 16, and its center is located on the rotation axis 16. Therefore, the rotation axis of the attachment body 19 overlaps with the rotation axis 16 of the screwdriver bit body 1. Further, the attachment body 19 is connected to the second base surface 15. in a preferred embodiment of the invention, the attachment body 19 has a hexagonal cross section and thus can be coupled to a female attachment component of an external torque tool. The external torque tool may be, but is not limited to: electric drills, torque wrenches, pneumatic drills, socket screwdrivers, and other similar torque tools. In a preferred embodiment of the present invention, the overall cross section of the bonding pocket 8 further comprises: a curved region, and a straight region. In other embodiments of the invention, the bonding pocket 8 may have other shaped cross-sections. Other shapes of profiles include, but are not limited to: square, rectangular, and part circular cross-sections. Furthermore, the shape of each region of the binding pockets 8 may be selected from a group comprising: straight line, concave line, and convex line. The combination of these shapes, or alone, may further improve the useful life, safety, and functionality of the present invention in certain applications selected by the user. In one embodiment of the invention, the overall cross-section 9 of the coupling pocket 8 is a triangular cross-section. When a torsion force is applied, at least one of the bonding pockets 8 is stressed to strain, and the triangular cross-section provides a large space to relieve the stress. Further, the triangular cross section may be a concave line in the direction from the first side edge 3 to the second side edge 4. In this case, during the application of torsion, the stresses are caught by the at least one coupling pocket 8. In other embodiments of the invention, at least one of the bonding pockets 8 has both curved and straight regions. This design allows the binding pocket 8 to optimally interact with different fastener profiles, different materials, different magnitudes of stress.

Some embodiments may be useful in applications where leverage and resistance to mechanical wear are beneficial. To achieve this, the first side edges 3 of the at least one bonding pocket 8 and the at least one particular sidewall 36 are separated by a first distance 21, as shown in fig. 9, 18, 19, 21, and 22. A clamping point is then created by one side 5 and at least one coupling pocket 8. The first portion 33 of the side 5 of at least one particular sidewall 36 is distributed along the first distance 21. Thus, the first distance 21 encompasses a section of the first portion 33. The width 35 of at least one of the coupling pockets 8 is parallel to the side 5. Such a design allows the width 35 to be parallel to the first distance 21. The width 35 may be greater than the first distance 21. In this way it is ensured that the at least one bonding pocket 8 covers a significant portion of the effective area of the side face 5.

In the present invention, the first portion 33 may have a variety of different shapes to provide optimal performance under a variety of stresses and conditions of use. To ensure that the at least one binding pocket 8 can have an appropriate shape, the shape of the first portion 33 can be selected from a group comprising: straight lines, concave lines, and convex lines, as shown in fig. 14 to 17. Any shape selected provides optimal support in use and improves the durability of the present invention.

The side 5 may be more advantageous from a more complex shape or design. For this purpose, the side 5 may further comprise: a second portion 34 as shown in figures 14 to 17. The second portion 34 is an area of the side 5, distributed along a second distance 22 such that the second portion 34 is adjacent to a second side edge 4. The second side edge 4 of at least one bonding pocket 8 and at least one particular sidewall 36 are spaced apart a second distance 22. The second distance 22 represents a space relative to the first distance 21 between the at least one bonding pocket 8 and the second side edge 4. The second portions 34 of the sides 5 of at least one particular sidewall 36 are distributed along the second distance 22. Thus, the second distance 22 encompasses a section of the second portion 34. The shape of the second portion 34 may be selected from a group comprising: straight line, concave line, and convex line. The second portion 34 thus allows the invention to be optimally adapted to potential mechanical fatigue. Further, at least one of the engaging pockets 8 tapers in a direction perpendicular to the axis of rotation and is directed from a position adjacent to either the first distance 21 or the second distance 22 toward one of the side edges. This design allows the present invention to optimally apply force when rotated. A lateral geometrical plane is distributed along the lateral surface 5 and is adjacent to the at least one joining recess 8. A skirt geometry plane extends from the first skirt 3 to the second skirt 4. In a preferred embodiment of the invention, the side geometric plane is collinear with the side edge geometric plane. In some embodiments of the invention, the side geometric plane is not collinear with the side edge geometric plane, but is remote from the side edge geometric plane.

In many situations, a user may wish to apply torque to an external screw from different angles. To this end, the second portion 34 of the side 5 of at least one particular side wall 36 is at an angle with respect to the first portion 33 of the side 5 of at least one particular side wall 36. This design allows other shapes of holes in the outer screw to be accurately filled with the present invention. This design is also within the scope of the present invention.

The triangular cross section may further comprise: a plurality of vertices 27, as shown in fig. 15. The plurality of vertices 27 are associated with the trajectories of the corners of the triangular profile. Each of the plurality of vertices 27 may be a rounded corner. This design prevents the accumulation of point stresses at the plurality of vertices 27 without significantly reducing the space required to effectively eliminate fatigue effects.

In many situations, depending on the strength of the torsional stress and the shape of the bolt or device, it may be advantageous to allow small modifications to be made to a strictly triangular profile. To achieve better efficiency in certain situations, the triangular profile may include: a plurality of vertexes 31, and a pair of extensions 32, as shown in fig. 16 and 17. The plurality of vertices 31 are associated with the trajectories of the corners of the triangular profile. The plurality of vertices 31 may be considered as two leading edge elements along the first and second side edges 3,4, or may be considered as a pocket base element. The pocket base element may also be a straight line connecting a pair of extensions 32. A pair of extensions 32 represents the edge connecting the plurality of vertices 31. That is, the pair of extensions 32 connects each of the plurality of vertices 31. The shape of each of the pair of extensions 32 may be selected from a group consisting of: straight line, concave line, and convex line. The shape of the base element as a plurality of vertices 31, a pair of extensions 32, or a pocket may be a rounded or an angular shape. Such a design allows the pair of extensions 32 to better accommodate different torsional stresses and prevents fatigue from adversely wearing the driver bit.

Other applications may require modification of the edges of the triangle profile perimeter. To achieve this, the side 5 may further comprise: a first portion 33, and a second portion 34, as shown in fig. 16 and 17. The first portion 33 and the second portion 34 are associated with edges surrounding the triangular cross section. The first portion 33 is distributed along a first distance 21 such that the first portion 33 is adjacent to the first side edge 3. Furthermore, the second portions 34 are distributed along a second distance 22 such that the second portions 34 are adjacent to the second side edges 4. The shape of the first portion 33 and the second portion 34 may be selected to be a rounded or an angular shape, as shown in fig. 16 and 17. It is most advantageous for the first portion 33 and the second portion 34 to exhibit opposite curvatures, for example: one of which is concave in shape and the other is convex in shape, so that the cyclic stresses acting on the present invention can be most effectively eliminated. Further modifications may also be applied to the first side edge 3 and the second side edge 4 to form a rounded or angled side edge.

Please refer to fig. 3 and fig. 4. Each of the plurality of side walls 2 further comprises: a first side edge 3, a second side edge 4, and a side surface 5. The plurality of side walls 2 are radially distributed about the rotational axis 16 of the screwdriver bit body 1, thereby creating a geometric profile complementary to a socket fastener. The number of side walls 2 depends on the shape and cross section of the socket fastener. In one embodiment of the invention, the number of side walls 2 is 6, which results in a hexagonal screwdriver bit body 1. In another embodiment of the present invention, the number of the plurality of side walls 2 is 4.

The side 5 physically abuts the side wall of the socket fastener, particularly the socket fastener head. The first side edge 3 and the second side edge 4 face each other via the side face 5. The first side edge 3 and the second side edge 4 of each of the plurality of side walls 2 form a corner of the screwdriver bit body 1, either from a top view or from a bottom view. In combination with the pockets 8, extend vertically from the plurality of side walls 2 into the side 5 of at least one particular side wall 36, thereby creating additional gripping points/teeth on the side 5. In other embodiments of the invention, the gripping point is created by the bonding pocket 8 and an adjacent edge, which may be the first side edge 3 or the second side edge 4, especially the side edge closest to the bonding pocket 8. Furthermore, the coupling pocket 8 extends on the screwdriver bit body 1 from the first base 14 to the second base 15. This ensures that additional gripping points extend along the length of the bit body 1, whereby maximum gripping force between the bit body 1 and the socket fastener is obtained. To achieve this more effectively, an overall section 9 of the bonding pocket 8 is parallel to the first base surface 14 and the second base surface 15. In some embodiments of the invention, at least one of the bonding pockets 8 tapers from the first base surface 14 to the second base surface 15, as shown in FIG. 11. In this embodiment, at least one bonding pocket 8 tapers from the first base surface 14 to the second base surface 15 in a manner described below: the triangular cross-section near the first base 14 is larger than the triangular cross-section near the second base 15. In this way, the shape of the at least one engagement cavity 8 can be varied as appropriate to suit the needs of the user. In one embodiment of the invention, the overall cross-section 9 of the binding pocket 8 is a semicircular cross-section, as shown in fig. 3. Furthermore, the semicircular cross section is recessed from a direction perpendicular to the line connecting the first side edge 3 and the second side edge 4. This semicircular profile ensures that: there are no or few points of high stress on the screwdriver bit body 1. Thus, the overall life of the tool is increased. In other embodiments of the invention, the overall cross-section 9 of the bonding pocket 8 is a triangular cross-section, as shown in fig. 13 and 14. Furthermore, the triangular cross section is concave from the direction perpendicular to the line connecting the first side edge 3 and the second side edge 4. Other profiles that may be used for the binding pockets 8 may be, but are not limited to: a half square cross section, a half rectangular cross section, or a half elliptical cross section.

Please refer to fig. 8 and 9. In one embodiment of the invention, the integral section 9 of the coupling pocket 8 comprises: a curved region 10 and a straight region 11. In this embodiment, the invention is embodied in the form of a removal bit, wherein the invention is designed to remove damaged fasteners, damaged screws, damaged bolts, and the like. In this embodiment, the engagement cavity 8 is given a special shape to form sharp engagement teeth that grip the corners of the socket fastener, allowing material to enter the engagement cavity 8 from the interior of the socket fastener, creating a gripping force that is far superior to conventional tools. In contrast to the present invention, conventional tools are simply designed to push material. The clamping force of the present invention is particularly effective against worn or broken fastener sockets. More specifically, the curved region 10 is a semi-circular curve adjacent to the first side edge 3. The curvilinear region 10 is adjacent to the first portion 33 of the side 5 of at least one particular side wall 36 and opposite the first side edge 3. This design allows the first portion 33 to effectively position the curvilinear region 10 relative to the first distance 21. The linear region 11 is adjacent to the curvilinear region 10 and is opposite the first portion 33. The linear region 11 guides a portion of the socket fastener against the engagement tooth. Thus, the straight region 11 extends from the curved region 10 to the second side edge 4. More specifically, the rectilinear region 11 starts from the curvilinear region 10 and ends at the second lateral edge 4.

Please refer to fig. 11. In one embodiment of the invention, the coupling pocket 8 is located in the center of the side 5. More specifically, the bonding pocket 8 is spaced a second distance 22 from the second side edge 4 of at least one particular sidewall 36. To be centrally located, the first distance 21 is equal to the second distance 22, as shown in fig. 15. Such a design enables the engagement cavity 8 to grip the socket fastener and move torsional stresses toward or away from the fastener side corners to enhance the gripping function and prevent fastener deactivation to most effectively transfer torque and minimize the possibility of slippage. Furthermore, the present embodiment may rotate the socket fastener in either a clockwise or counterclockwise direction. In one embodiment of the present invention, a plurality of intermittent sidewalls 24 are interposed between at least one specific sidewall 36, and the first distance 21 is equal to the second distance 22, as shown in fig. 19 and 22.

In one embodiment of the invention, the ratio between the first distance 21, the second distance 22, and the width of the binding pocket 8 may be varied to achieve a dedicated clockwise or counterclockwise design. In one embodiment of the invention, the invention is a driver bit that is programmed to be a clockwise bit. In this embodiment, the second distance 22 is greater than the first distance 21. More specifically, the ratio between the first distance 21, the second distance 22, and the width of the bonding pocket 8 is 1:5:4 whereby a design of the present invention is achieved that clamps and applies torsion to the socket fastener in a clockwise direction. This one design is used to screw in and secure a socket fastener. In one embodiment of the invention, the invention is a driver bit that is programmed to be an inverted clock. In this embodiment, the first distance 21 is greater than the second distance 22. More specifically, the ratio between the first distance 21, the second distance 22, and the width of the bonding pocket 8 is 5:1:4 whereby a design of the present invention is achieved that clamps and applies torque to the socket fastener in a counter-clockwise direction. This one design is used to loosen and remove socket fasteners.

Please refer to fig. 5 and 10. The invention may be embodied in the form of a key slot, square, or other polygonal driver head. In one embodiment of the present invention, the bit body 1 is a key-slot type bit body, so that the key-slot type bit body can transmit torque to the socket fastener through a plurality of protrusions. In one embodiment of the present invention, the screwdriver bit body 1 further comprises: a plurality of intermittent side walls 24 as shown in fig. 18-22. Each of the plurality of intermittent sidewalls 24 is a planar surface that incorporates socket fasteners in a manner similar to a conventional screwdriver design. A plurality of intermittent side walls 24 are radially distributed about the axis of rotation 16. Furthermore, a plurality of intermittent side walls 24 are interposed between the plurality of side walls 2. The ratio of the plurality of sidewalls 2 to the plurality of intermittent sidewalls 24 may be varied to create different screwdriver bit designs. In one embodiment of the present invention, the plurality of intermittent sidewalls 24 and the plurality of sidewalls 2 are intermittently radially distributed with respect to each other. In one embodiment of the invention, three intermittent side walls 24 are present in each side wall 2. Such an arrangement allows one engagement feature _/ to engage the teeth, on every other protrusion of each screwdriver bit body 1.

In an exemplary embodiment of the present invention, a first intermittent sidewall 28, a second intermittent sidewall 29, and a third intermittent sidewall 30 of the plurality of intermittent sidewalls 24 are interposed between the associated sidewalls of the plurality of sidewalls 2, as shown in fig. 10. The first intermittent sidewall 28, the second intermittent sidewall 29, and the third intermittent sidewall 30 can be effectively connected to the fastener, but still provide sufficient space to prevent mechanical wear and fatigue. The first intermittent sidewall 28 and the second intermittent sidewall 29 are perpendicular to each other. Such a design forms a 90 degree angle that can be best used in some applications. The third intermittent sidewall 30 is located between at least one bonding pocket 8 of the associated sidewall and the second intermittent sidewall 29. Thus, in the application of the present invention, the third intermittent sidewall 30 provides mechanical support for the at least one bonding pocket 8.

Providing at least one different configuration of the coupling pockets 8 may be mechanically advantageous and may be considered as a preferred embodiment, for example: at least one engaging recess 8 is formed in a plurality of side walls of the at least one screwdriver bit body 1. For this purpose, the at least one specific sidewall 36 may be a plurality of specific sidewalls. This design allows a plurality of specific sidewalls to surround the screwdriver bit body 1 in different configurations. Furthermore, the at least one bonding pocket 8 may be a plurality of bonding pockets. In this way, each particular sidewall can be suitably shaped with one of the bonding pockets 8. Each of the plurality of engagement pockets 8 may then vertically access the side 5 of an associated one of the plurality of particular side walls. Thus, each particular sidewall may be formed into a cavity or other shape by one of a plurality of bonding cavities 8.

To achieve this, the plurality of side walls 2 may further comprise at least one flat side wall 37. At least one flat sidewall 37 is a sidewall of the plurality of sidewalls 2 that does not have a particular pocket feature. The at least one flat sidewall 37 may be contiguous with the at least one particular sidewall 36. Thereby, the flat sidewalls may be located between at least one specific sidewall 36 and different configurations of the concave and flat sidewalls may be formed.

Please refer to fig. 6. In one embodiment of the present invention, the present invention further includes a coupling hole 20. The coupling holes 20 allow the present invention to be attached to a male attachment feature of an external torque tool, such as a socket wrench or screwdriver. The coupling hole 20 extends into the attachment construction body 19 and is opposite to the screwdriver bit body 1. The coupling aperture 20 is shaped to receive the male attachment formation of the socket wrench. The shape of the coupling hole 20 is preferably square because most socket wrenches use a square attachment configuration. In this embodiment, the attachment formation body 19 is preferably cylindrical in shape. In other embodiments, the shape of the coupling hole 20 and the attachment configuration body 19 may vary with the design of the torque tool and the method of attachment.

Please refer to fig. 2. In one embodiment of the present invention, the present invention is fabricated as a double ended screwdriver bit that provides both clockwise and counterclockwise configurations in a single tool. In this embodiment, the screwdriver bit body 1 includes: a first screwdriver bit body 17 and a second screwdriver bit body 18. The attachment formation body 19 is preferably hexagonal in cross section. The center of the attachment structure body 19 is located at the rotation axis 11 of the first screwdriver bit body 17 and is distributed along the rotation axis 16 of the first screwdriver bit body 17. Therefore, the rotation axis of the attachment structure body 19 is completely overlapped with the rotation axis 16 of the first driver bit body 17. The attachment formation body 19 is connected to the second base surface 15 of the first screwdriver bit body 17. The second head body 18 shares the attachment structure body 19 with the first head body 17, and the second head body 18 is concentric with the first head body 17. Similar to the design of a conventional double-ended screwdriver bit, the second screwdriver bit body 18 is connected to the attachment formation body 19 and is opposite to the first screwdriver bit body 17. Like the first screwdriver bit body 17, the attachment formation body 19 is connected to the second base surface 15 of the second screwdriver bit body 18. The first screwdriver bit body 17 is used to rotate the socket fastener in a clockwise direction, that is to say the first screwdriver bit body 17 is a screwdriver bit body in a clockwise configuration. Please refer to fig. 3. The second distance 22 of the first screwdriver bit body 17 is greater than the first distance 21 of the first screwdriver bit body 17. As such, the additional gripping points of the first screwdriver bit body 17 are adjacent to the first side edge 3 of the first screwdriver bit body 17. The second bit body 18 is used to loosen or remove socket fasteners from a counter-clockwise direction, i.e., the second bit body 18 is a counter-clockwise configured bit body. Please refer to fig. 4. The first distance 21 of the second bit body 18 is greater than the second distance 22 of the second bit body 18. As such, the additional gripping points of the second bit body 18 are adjacent to the second side edge 4 of the second bit body 18.

In one embodiment of the present invention, a double ended screwdriver bit may facilitate: an elbow is established between the first and second screwdriver bit bodies 17, 18 as is common with allen wrenches or similar wrench tools. To this end, the second screwdriver bit body 18 may be attached at an angle 38 relative to the first screwdriver bit body 17, as shown in fig. 21. Such a design allows the user to rotate an external screw using the second screwdriver bit body 18 with the first screwdriver bit body 17 as a handle.

Please refer to fig. 5. In one embodiment of the invention, the binding pocket 8 comprises: a first pocket 12 and a second pocket 13. This embodiment is another configuration of the present invention having both clockwise and counterclockwise functionality. The first and second pockets 12, 13 are parallel to each other and are spaced apart from each other. The first pocket 12 is adjacent the first side edge 3 and is spaced from the first side edge 3 and the second pocket 13 is adjacent the second side edge 4 and is spaced from the second side edge 4. This embodiment allows the user to rotate the present invention clockwise or counterclockwise without removing the present invention from the torque tool and still have the advantage of additional gripping points. In this embodiment, the present invention preferably includes a plurality of intermittent sidewalls 24, wherein the plurality of intermittent sidewalls 24 are interposed between the plurality of sidewalls 2. Thus, in this embodiment, the triangular profile may be a plurality of triangular profiles arranged along a plurality of sidewalls 2. Such a design allows the present invention to accommodate a wide variety of high stress applications.

Please refer to fig. 7. In one embodiment of the invention, the invention is manufactured as a screwdriver bit with spherical end points. In this embodiment, each side 5 of the plurality of side walls 2 comprises: a convex surface 6 and a concave surface 7. The convex surface 6 and the concave surface 7 form a curved surface. Thus, the screwdriver bit body 1 having a plurality of side walls 2 forms a sphere-like configuration. The convex surface 6 is adjacent to the first base surface 14; each convex surface 6 of the plurality of side walls 2 participates in forming together a sphere-like configuration. The concave surface 7 is adjacent to the convex surface 6 and opposite to the first base surface 14; each concave surface 7 of the plurality of side walls 2 participates in forming together a sphere-like configuration; the concave surface 7 may provide a suitable clearance when the screwdriver bit body 1 is engaged at an angle to a socket fastener. The convex surface 6 and the concave surface 7 are distributed along the rotation axis 16 of the screwdriver bit body 1 (i.e. along the length of the screwdriver bit body 1) such that the spheroidal configuration ends at one end of the screwdriver bit body 1. In a preferred embodiment of the present invention, the curvature, height, and length of the convex surface 6 are the same as the curvature, height, and length of the concave surface 7, respectively. In a preferred embodiment of the invention, the coupling pocket 8 extends the entire length of the convex surface 6 and the concave surface 7. Thus, no matter what the angle between the socket fastener and the screwdriver bit body 1, additional clamping points or teeth are created on the screwdriver bit body 1.

Please refer to fig. 10. In one embodiment of the present invention, the present invention is manufactured as a tamper-proof screwdriver bit. In this embodiment, the present invention includes a latch safety vent 23; the latch relief aperture 23 is complementary to the shape of the latch on a unique socket fastener and is capable of interlocking with this latch. In accordance with this embodiment, a series of unique socket fasteners and unique screwdriver bits can be manufactured, used, and sold. This interlocking design is for security reasons to prevent unauthorized persons from using or operating certain socket fasteners. The latch safety hole 23 is concentrically located on the rotation shaft 16 of the screwdriver bit body 1. Further, a detent safety hole 23 extends from the first base surface 14 into the screwdriver bit body 1. The size, depth, and cross-sectional shape of the latch safety aperture 23 may be varied to suit the needs or specifications of the user.

Please refer to fig. 11. In some embodiments, the present invention further includes additional features to assist the user in guiding the screwdriver body 1 into the socket fastener. In one embodiment, the present invention further comprises a side edge 25; the material between each of the plurality of side walls 2 and the first base surface 14 is chamfered to form a skirt 25. The side edges 25 may assist the user in locking the screwdriver bit body 1 into the socket fastener. Please refer to fig. 12. In one embodiment, the invention is implemented in another design. In this embodiment, the screwdriver bit body 1 tapers from the second base 15 to the first base 14. The degree of tapering may vary depending on the needs of the user. Please refer to fig. 22. The present invention is a screwdriver bit body tapering from a second base surface 15 to a first base surface 14 comprising: at least one planar sidewall 37, wherein the planar sidewall 37 is adjacent to the at least one tapered specific sidewall 36. In other words, the at least one specific sidewall 36 and the at least one planar sidewall 37 are not perpendicular to the first base surface 14, as shown in fig. 22. In use, certain embodiments of the present invention are more conducive to leverage and resistance to mechanical wear. To achieve this, the first side edges 3 of the at least one engagement recess 8 and the at least one particular side wall 36 are separated by a first distance 21, as shown in fig. 22. A clamping point is then created by at least one coupling pocket 8 and one side 5. The first portion 33 of the side 5 of at least one particular sidewall 36 is distributed along the first distance 21. Thus, the first distance 21 encompasses a section of the first portion 33. The width 35 of at least one of the coupling pockets 8 is parallel to the side 5. Such a design allows the width 35 to be parallel to the first distance 21. The width 35 may be greater than the first distance 21. In this way it is ensured that the at least one bonding pocket 8 covers a significant portion of the effective area of the side face 5.

The invention can be further advantageous from a side 5 of a more complex shape or design. For this purpose, the side 5 may further comprise: a second portion 34 as shown in fig. 22. The second portion 34 is an area of the side 5, distributed along a second distance 22 such that the second portion 34 is adjacent to a second side edge 4. The second side edge 4 of at least one bonding pocket 8 and at least one particular sidewall 36 are spaced apart a second distance 22. The second distance 22 represents a space relative to the first distance 21 between the at least one bonding pocket 8 and the second side edge 4. The second portions 34 of the sides 5 of at least one particular sidewall 36 are distributed along the second distance 22. Thus, the second distance 22 encompasses a section of the second portion 34. The shape of the second portion 34 may be selected from a group comprising: straight line, concave line, and convex line. The second portion 34 thus allows the invention to be optimally adapted to potential mechanical fatigue. Further, at least one of the engaging pockets 8 tapers in a direction perpendicular to the axis of rotation and is directed from a position adjacent to either the first distance 21 or the second distance 22 toward one of the side edges. This design allows the present invention to optimally apply force when rotated. The first distance 21 may or may not be equal to the second distance 22. The width distance of planar sidewall 37 may be less than, equal to, or greater than the width distance of a particular sidewall 36. The width of the first portion 33 and the width of the second portion 34 gradually decrease from the first base surface 14 to the second base surface 15. Please refer to fig. 22 again. In one embodiment of the present invention, it is preferable that: the overall cross-section 9 of the coupling pocket 8 is a semicircular cross-section. Furthermore, the semicircular cross section is recessed from a direction perpendicular to the line connecting the first side edge 3 and the second side edge 4. This semicircular profile ensures that: there are no or few points of high stress on the screwdriver bit body 1. Thus, the overall life of the tool is increased. In a preferred embodiment of the invention, the side 5 of at least one particular sidewall 36 is connected to the side 5 of at least one planar sidewall 37 at an obtuse angle. The attachment body 19 allows the present invention to be attached to an external torque tool whereby torque can be applied to the socket fastener via the screwdriver bit body 1. The attachment body 19 is distributed along one rotation axis 16 of the screwdriver bit body 1 and surrounds the rotation axis 16, and its center is located on the rotation axis 16. Therefore, the rotation axis of the attachment body 19 overlaps with the rotation axis 16 of the screwdriver bit body 1. Further, the attachment body 19 is connected to the second base surface 15.

In many situations, a user may wish to apply torque to an external screw from different angles. To this end, the second portion 34 of the side 5 of at least one particular side wall 36 is at an angle relative to the first portion 33 of the side 5 of at least one particular side wall 36, as shown in fig. 22. This design allows other shapes of holes in the outer screw to be accurately filled with the present invention. This design is also within the scope of the present invention.

In other embodiments, the invention may be embodied in the form of a socket for locking or unlocking a bolt or other similar fastener. To this end, the screwdriver bit body 1 is embodied in the form of a cavity penetrating a cylinder, just like a conventional socket design.

The invention has been described above by way of example, however it should be understood that: these examples are provided only for illustrating the present invention and are not intended to limit the scope of the present invention. Any modifications or variations that do not depart from the gist of the invention are intended to be within the scope of the invention.
