Wherein, the moving assembly 2 is movably arranged in the shell 1, the fixing pin 3 is fixedly arranged on the moving assembly 2, and the control assembly 4 is arranged in the shell 1 and is configured to control the moving assembly 2 to move.

Further, the control assembly 4 of the present embodiment includes a cam 41 and a driver 42, as shown in fig. 7. The driving member 42 is fixedly connected with the cam 41, and the cam 41 is rotatably arranged in the housing 1 and is abutted with the moving assembly 2. Therefore, the cam 41 can be rotated by the driving part 42, so as to drive the motion assembly 2 to move, and further the fixing pin 3 can clamp the workpiece. That is to say, the jig provided by the embodiment can work normally and effectively only by controlling the driving member 42, and the operation is simple and convenient.

Further, in the present embodiment, the moving assembly 2 includes a slider 21. The slider 21 is movably disposed in the housing 1, abuts against the cam 41, and is fixedly connected to the fixing pin 3. Therefore, the rotation of the cam 41 can drive the slide block 21 to move, so that the fixing pin 3 follows the movement to realize the clamping function.

In the present embodiment, the moving assembly 2 further includes a reset member 22, and two ends of the reset member 22 are respectively connected to the housing 1 and the slider 21. The slide 21 can thereby be moved back and forth relative to the housing 1 by the restoring element 22, i.e. the clamping function of the fixing pin 3 is achieved by the restoring element 22. The restoring member 22 of the present embodiment is a compression spring, and may be an elastic member made of an elastic material such as memory alloy as needed. The slide 21 can be reset by the spring force of the compression spring, i.e. the fastening pin 3 is clamped.

The slide rail 23 is fixedly arranged in the housing 1, and the slide block 21 is slidably arranged on the slide rail 23. For the component which does the straight reciprocating motion, the slide rail 23 plays a role in supporting and guiding the slide block 21, and the slide rail 23 prevents the slide block 21 from shifting in the moving process, that is, the fixing pin 3 does not shift, so that the effective clamping work can be carried out.

It should be noted that, in the present embodiment, the number of the moving assemblies 2 is two, and the moving assemblies are respectively disposed on both sides of the cam 41. From this, can drive the motion subassembly 2 of both sides simultaneously through cam 41 and take place to remove, also drive the fixed pin 3 of both sides and take place to remove, enlarged the clamp stroke of getting of tool to a certain extent to can the bigger object of centre gripping size. In other embodiments, a plurality of motion assemblies 2 may be provided, and the selection of the specific number may be provided according to needs, and is not limited herein.

Further, the jig of the present embodiment further includes a fixing table 5. The fixed table 5 has a through hole 51 and is fixedly disposed between the two moving assemblies 2. The fixing pin 3 passes through the through hole 51 and is movable along the through hole 51. Thereby, the object is placed on the fixing table 5, and the object can be clamped by the fixing pin 3 passing through the through hole 51.

As shown in fig. 3 and 8, the bottom of the fixing base 5 has a rectangular mounting groove 52, the housing 1 has a rectangular boss 14 matching the mounting groove 52, and the fixing base 5 is fixedly mounted on the housing 1 through the mounting groove 52 and the boss 14.

Further, in the present embodiment, the cam 41 is provided as a disk-like structure symmetrical about the center, and includes a first contact surface a and a second contact surface b on the side surfaces. Wherein, the distance between the first contact surface a and the rotating shaft 6 is larger than that between the second contact surface b and the rotating shaft 6. The distance between the first contact surface a and the second contact surface b relative to the rotating shaft 6 is changed, so that the sliding assembly 2 can be controlled to reciprocate, namely, the fixing pin 3 can linearly reciprocate under the matching action of the cam 41 and the resetting piece 22, and the clamping function can be realized.

It should be noted that the housing 1 of the present embodiment has a limiting groove 11, and the cam 41 is disposed in the limiting groove 11. The cam 41 can only rotate on the same plane relative to the shell 1 through the limiting groove 11, so that the fixed pin 3 is prevented from moving and deviating due to the rotation deviation of the cam 41, and the fixed pin 3 can normally complete clamping work.

As shown in fig. 9, the housing 1 of the present embodiment further has a rotating shaft hole 12 and a bearing hole 13 communicating with the limiting groove 11, and the center lines of the rotating shaft hole 12 and the bearing hole 13 are the rotating center lines of the cam 41. Wherein, the rotating shaft hole 12 is internally provided with a rotating shaft 6, and the rotating shaft 6 is connected with a cam 41. The bearing hole 13 is internally provided with a bearing 7, and the bearing 7 is arranged on the rotating shaft 6. The cam 41 can be supported to rotate through the rotating shaft 6 and the bearing 7, the friction coefficient in the rotating process of the cam 41 is reduced, and the rotation precision is ensured.

As shown in fig. 7, in this embodiment, the driver 42 is a handle. The lever structure formed by the handles can ensure that the state switching of the jig is more labor-saving and time-saving.

Specifically, referring to fig. 10, when the driving member 42 is operated to make the first contact surface a of the cam 41 abut against the sliding block 21, and the moving assembly 2 is at the first position, the sliding block 21 is far away from the rotating shaft 6, that is, the fixing pin 3 is far away from the rotating shaft 6, so that the object can be placed conveniently. As shown in fig. 11, by manipulating the driving member 42 and under the action of the restoring member 22, the sliding block 21 moves to a direction close to the rotating shaft 6, and the moving assembly 2 is at the second position, the second contact surface b of the cam 41 abuts against the sliding block 21, and the distance from the fixed pin 3 to the center of the cam 41 is short, so as to clamp the object.
