[0021] The crank-connecting rod mechanism includes a cam 5 and a sleeve 10. The cam 5 is fixedly sleeved on the outside of the main shaft 4. A pin 8 is fixedly installed on the inner wall of the movable block 7. A bearing 9 is sleeved on the outside of the pin 8. The sleeve 10 is fixedly sleeved on the outside of the bearing 9. The bearing 9 is used to reduce the rotational resistance of the sleeve 10. The outside of the sleeve 10 is rollingly connected to the outside of the cam 5 to reduce the rotational resistance of the sleeve 10 and avoid excessive wear of the cam 5 and the sleeve 10.

[0022] The transverse return mechanism includes a transverse guide rod 16 and a transverse return spring 17. Two guide seats 15 are fixedly connected to both sides of the limit block 13. The transverse guide rod 16 and the guide seat 15 are slidably connected. The transverse return spring 17 is sleeved on the outer side of the transverse guide rod 16. A baffle is fixedly sleeved on the outer side of the transverse guide rod 16. The baffle is used to limit one end of the transverse return spring 17. Figure 1 At this time, the transverse return spring 17 is in a partially compressed state.

[0023] A longitudinal guide rod 18 is fixedly installed inside the longitudinal plate 2, and a longitudinal return spring 19 is sleeved on the outer side of the longitudinal guide rod 18. The longitudinal return spring 19 is used to reset the movable block 7. Figure 1 At this time, the longitudinal return spring 19 is in a partially compressed state.

[0024] Both sides of the movable block 7 are fixedly connected with a connecting plate 20, one end of the connecting plate 20 is slidably sleeved on the outer side of the longitudinal guide rod 18, and the outer side of the longitudinal guide rod 18 is sleeved with a gasket 6.

[0025] The working principle and process of this utility model are as follows: Figure 1It is the initial state. When the operator uses it, the operator pulls the limit plate 14 to a certain position, and the operator places the central locking part to be assembled inside the limit block 13. The operator releases the limit plate 14. Under the elastic action of the horizontal return spring 17, the limit plate 14 begins to return until the central locking part is clamped. The operator places another part to be assembled on top of the clamped part and aligns it.

[0026] The operator operates the button to control the output shaft of the motor 3 to drive the main shaft 4 to rotate clockwise, and the main shaft 4 drives the cam 5 to rotate. During the process of the cam 5 rotating from the top dead center to the bottom dead center, the longitudinal return spring 19 is compressed, and the sleeve 10 rotates and moves downward relative to the cam 5, thereby causing the movable block 7 to drive the longitudinal rod 11 to move downward, and the longitudinal rod 11 drives the pressure block 12 to squeeze and clamp the two parts together. Then, when the cam 5 moves from the bottom dead center to the top dead center, under the elastic action of the longitudinal return spring 19, the connecting plate 20 drives the movable block 7 to move upward together to Figure 1 State position, the operator then pulls the limit plate 14 and takes out the parts.
