Description
Technical field
The utility model relates to a kind of hand-operated tools field, specifically a kind of ratchet spanner.
Background technology
Existing ratchet spanner is tooth and swing pinion (or ratchet) engagement that utilizes a ratchet, and it is arranged in the opening of Wrench head.Ratchet can limit the opening of a shaping, directly to cooperate or to hold a special insertion instrument with nut.When work, afterburning position can be subjected to the angle limits of hook tooth to spanner next time from the application of force to the return, can not stop at an arbitrary position, has therefore limited usage space and angle, is difficult for using in the narrow and small scope in space.Because ratchet is the face contact, and is stuck easily when torsion is excessive, causes ratchet spanner temporarily to lose efficacy; In addition, the adjustment knob structure of ratchet spanner is quick detachable, and parts such as reversing piece are fragile or lose, and can cause spanner to be damaged and can't use.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, compact, reasonable in design, low cost of manufacture, easy to use, ratchet spanner flexibly.
The utility model solves the scheme that its technical problem takes: a kind of ratchet spanner, an end that it is characterized in that handle connects head, head is provided with circular hole, its circular hole inner edge two ends are provided with ring-like draw-in groove, be provided with the rotating body head of pulling in the circular hole, the centre of pulling the body head is provided with cubic through hole, the centre of through hole one side is provided with groove, the two ends of pulling the body head are circular platform type, and middle circumference is provided with breach, and two planes of breach are vertical mutually, wherein a plane is provided with circular hole, be provided with spring in the circular hole, in breach, be provided with needle roller, pull the body head and be contained in the middle of the circular hole, two ends are provided with end cap, end cap is provided with cannelure, is provided with check ring in the cannelure, and check ring enters the interior fixedly end cap of ring-like draw-in groove of circular hole inner edge.
Of the present utility model pulling is evenly distributed with 3 breach on the body head intermediate circumference.
The utility model is reasonable in design, and is simple in structure, compact, easy to manufacture, cost is low, easy to use, is not subjected to angle of revolution and spatial constraints, realizes the ratchet spanner commutation by using anyway face.
The utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the exploded view of Fig. 1 right view.
Mark among the figure: 1, handle, 2, check ring, 3, end cap, 4, spring, 5, needle roller, 6, pull the body head, 7, the four directions rod.
The specific embodiment
As Fig. 1, shown in Figure 2: a kind of ratchet spanner, one end of its handle 1 connects head, head is provided with circular hole, its circular hole inner edge two ends are provided with ring-like draw-in groove, be provided with the rotating body head 6 of pulling in the circular hole, the centre of pulling the body head is provided with cubic through hole, the centre of through hole one side is provided with groove, the two ends of pulling the body head are circular platform type, and middle circumference is provided with breach, and two planes of breach are vertical mutually, wherein a plane is provided with circular hole, be provided with spring 4 in the circular hole, in breach, be provided with needle roller 5, pull the body head and be contained in the middle of the circular hole, two ends are provided with end cap 3, end cap is provided with cannelure, is provided with check ring 2 in the cannelure, and check ring enters the interior fixedly end cap 3 of ring-like draw-in groove of circular hole inner edge.Pull and be evenly distributed with 3 breach on the body head intermediate circumference, pull in the cubic through hole in the middle of the body head 6 and be provided with the four directions rod, be respectively equipped with locking ball on the side, two ends of four directions rod 7.
During assembling, earlier 1 check ring 2 is put in the groove of end cap 3, being placed to handle 1 one ends after clutching connects on the ring-like draw-in groove of circular hole inner edge of head, pull body head 6 two ends and be circular platform type, be evenly distributed with 3 breach on the middle circumference, two planes of breach are vertical mutually, wherein a plane is provided with circular hole, with calcium base lithium fat 3 springs 4 are placed in the circular hole on the plane, 3 needle rollers 5 are put on the breach plane of pulling body head 6, clutch the back pulling in the circular hole that body head 6 installs to handle 1 head, after debugging is rotated flexibly, again 1 check ring 2 is put in the groove of end cap 3, is placed to after clutching on another ring-like draw-in groove of circular hole inner edge of handle 1 head and can finishes.It is rational in infrastructure, and processing is simple, and is easy to assembly, time saving and energy saving, the production efficiency height.
Breach and spring, the needle roller pulled on the body head can realize reversing the function of easily, just changeing the application of force, and spanner is not subjected to the restriction in angle and space in the position of the application of force from the application of force again to return next time, and operation all can be used in the optional position; Pulling the body head is positioned in the circular hole of handle 1 head by the connection of the check ring on the end cap.Pull during use and add the four directions rod in the cubic through hole of body head, location, one on excellent side, four directions steel ball enters the groove in the cubic through hole, rod location, four directions, with jacket casing on cubic rod, finish with sleeve and be connected, turning handle 1 drives the sleeve rotation can realize rotation to workpiece.The four directions rod inserts in the cubic through hole from the front, and rotary handle is realized the purpose of holding screw; Insert from the back side and to be rotated the purpose that can realize loosening screw in the cubic through hole, realize the commutation function of ratchet spanner thus.Because the elasticity of spring 4 can both contact needle roller 5 at any time with the circular hole interior surface of handle 1 head, when the power of applying is just being changeed handle 1, pulling breach plane on the body head 6 drives needle roller 5 to make that needle roller 5 contacts with circular hole interior surface tightr, make spring 4 compressions, strain increases torque value, thereby drive sleeve rotation, reach the purpose that tightens nut, when the power on being applied to handle 1 is cancelled, strain finishes, and needle roller 5 returns to original contact condition with circular hole interior surface, can not make spanner stuck, when the power that applies on handle 1 makes handle 1 counter-rotating, the bore area of handle 1 promotes needle roller 5 and moves pulling on the breach plane of body head 6, compression spring 4, thus realize the reverse functions of common ratchet spanner, only need very little power to get final product, when the power on being applied to handle 1 was cancelled, needle roller 5 stopped to compress spring 4, and spring 4 is bound to needle roller 5 with circular hole interior surface again and contacts, and latched position, realize that the optional position stops.Be inserted in the cubic through hole of pulling body head 6 from the front cubic excellent 7, the intermediate groove that the locking ball on excellent 7 sides, four directions enters the through hole side, it is the effect of practicable common ratchet spanner that jacket casing turning handle 1 drive sleeve on the rod 7 of four directions is rotated.Commutation is used as need, the four directions rod is inserted from the reverse side of pulling body head 6 get final product.The utility model is rational in infrastructure, and processing is simple, and is easy to assembly, to the requirement of parts relatively like product require lowly, use simple, conveniently not to be subjected to spatial constraints, time saving and energy saving, high efficiency.
