Abstract

The present invention provides a screw holder suitable for a driver bit which has a long or short length and is selectively exchanged depending on the working purpose in a manual driver or an electric driver. The screw holder has a pole shape. In addition, linear or cruciform tips for applying screwing force of a screw are provided at both ends of the screw holder. Mounting grooves for being detachably coupled with a driver body are formed inside the tips. The screw holder includes: a stator detachably installed at one end of the driver bit by using the mount grooves through an elastic support element, and a mover moving backwards and forwards while riding on the stationary element and including grasping elements for elastically supporting a pillar of the screw mounted on the tips of the driver bit. Therefore, convenient installation can be achieved by using the simple elastic support element. Further, the screw can be stably grasped, thereby improving the screwing workability.

Description

Screw holder suitable to driver beat}

The present invention relates to a screw holder suitable for a driver bit having a long and short length in a manual screwdriver or an electric screwdriver, and selectively used in accordance with a work application.

In the manual or electric screwdriver, the driver bit, which has long and short lengths and is used as a replacement depending on the work purpose, is roughly rod-shaped, and is provided with straight or shovel-shaped tips that apply screw tightening force to both ends. On the inner side of the wheel, there are mounting grooves for the driver body and detachable engagement.

These driver bits are mounted on the tip of the end of the screw to move to the working position to achieve the desired screw assembly work, where the tip is magnetized to prevent separation of the screw mounted on the tip to prevent workability However, when the screw is dependent only on the magnetic force of the tip, the mounting is unstable, and when the external force is applied, the screw is frequently disengaged from the tip, and workability is deteriorated.

Thus, in recent years, a structure for preventing screw detachment, which is additionally installed in the driver bit, has been developed and used. Such a screw detachment prevention structure has a substantially tubular shape, and the driver bit is inserted to one side to bind using a separate binding element. • At the same time, the main wall was partially cut off and discarded in the width direction on the other side, so that the head of the screw was held or released by using the gripping portion.

However, in the screw detachment prevention structure, as shown above, the binding or disengagement with the driver bit is made by using a fastening element such as a screw, thereby increasing the parts of the fastening structure, as well as the work of tightening and releasing the fastening element when the fastening and disengagement of the fastening structure. This is cumbersome to follow.

In addition, by holding only the head circumference of the screw by using a gripping portion formed by partially cutting the circumference of the binding structure, there are many problems such as the screw mounting state is very unstable, and easily detached when the screw is long. It is following.

Domestic Application 10-2010-23413

The present invention has been made in consideration of the above circumstances, and its object is to enable easy detachment and retraction of the elastic support element by using the mounting groove of the driver bit, and to move in and out to stably hold the screw mounted on the tip of the driver bit. In addition, the present invention provides a screw holder suitable for a replaceable driver bit that can improve screw assembly workability.

The object of the present invention is achieved by providing a screw holder suitable for a driver bit having a long and short length in a manual screwdriver or a motorized screwdriver and optionally being replaced according to a work purpose. The screw holder is formed in a rod shape. Suitable for replaceable driver bits with straight or cross-shaped tips that apply screw tightening force to both ends, and with mounting grooves for engaging the driver body and detachable type inside the tips. It consists of a stator that can be detachably installed with a resilient support element using a mounting groove, and a mover equipped with holding elements that elastically support a column of screws mounted on the tip of a driver bit while moving in and out of the stator. Using elastic support elements Comfortably it is possible to set up and improve the workability by holding screws to stabilize the screw.

According to the screw holder suitable for the replaceable driver bit according to the present invention, the screw holder is easily detached to the mounting groove of the driver bit using the elastic support element, so that the installation and dismantling of the holder is simple and easy to use. have.

In addition, the present invention by using the gripping element of the mover in and out of the stator installed in the driver bit to securely hold the pillar of the screw, preventing the screw from easily detached from the tip of the driver bit when moving the power tool to the working position Thus, the screw work is stable and thus the work efficiency can be improved.

1 is a perspective view showing the appearance of a screw holder suitable for the present invention replaceable driver bit.
2 is a cross-sectional view showing the screw holder of the present invention mounted on the driver bit.
Figure 3 (a) (b) (c) is an explanatory view showing the operation of the screw holder of the present invention.

Next, an embodiment of the present invention will be described.

The present invention is to provide a holder for stably holding the screw for the screw work is installed in the driver or by a screwdriver of the driver bit is installed in addition to the tip of the driver bit to be selectively replaced according to the working purposes will be.

1 and 2 show in detail a screw holder suitable for a replaceable driver bit according to the invention.

First, the driver bit 10, which selectively replaces the length of the long and short lengths according to the work purpose in the manual or electric type driver as described above, has a substantially bar shape and has a straight or shovel type to apply screw tightening force to both ends. The upper tips 12 are provided, and inside the two tips 12, there are mounting grooves 14 for binding the manual or electric driver body and the detachable method.

Such a replaceable driver bit 10 is the same as in the prior art, the core technology in the present invention when moving the screw 20 mounted for screwing on the tip 12 of the driver bit 10 to the working position It is to provide a holder for storing stably.

The screw holder 30 of the present invention is composed of a stator 32 and a mover 34 which freely moves in and out of the stator 32 to be fitted into each other. The in and out of the mover 34 may be automatically returned by the resilient restoring element in relation to the stator 32.

First, the stator 32 is formed in a hollow tubular shape so as to be freely inserted into the driver bit 10, and the stator 32 inserted into the driver bit 10 is elastically supported at one end. Detachable to the mounting groove 14 provided in the driver bit 10 by using a).

In addition, the mover 34 is formed in a fallopian tube shape and grips elements 34a that elastically support the column of the screw 20 mounted on the tips 12 of the driver bit 10 while moving in and out of the stator 32. It is provided.

Referring to the operation of the screw holder of the present invention with reference to (a) (b) (c) of Figure 3, Figure 3 (a) is a state before the screw holder 30 is mounted on the driver bit (10). It is showing.

3 (b) shows that the screw holder 30 is secured by using the mounting groove 14 of the driver bit 10 and the screw 20 is stabilized by the holding elements 34a of the mover 34. It looks like it's been kept.

3 (c) shows that the screw bit 20 is driven to the object side by applying a tightening force by the driving force transmitted from the driver bit 10 by a manual or electric drive, and the screw 20 is driven to the object side. When driven, the mover 34 is pushed toward the driver bit 10 side, and at the same time, the holding element 34a of the holder 30 is pushed outward by the head of the screw 20, and the screw binding operation is completed. The gripping element 34a returns to its original state and waits for the next operation.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
