A movable block 11 is movably installed in the sliding groove 9. The movable block 11 is threadedly connected to the sliding groove 9. A pair of clamping plates 12 are arranged at the top of the movable block 11.
[0023] In this embodiment, a slider 16 is fixedly installed at the bottom of the clamping plate 12. An adjustment groove 15 is opened at the top of the movable block 11.

The fixed block 4 can be controlled to move toward the middle through the threaded rod 5. The distance between the fixed blocks 4 is adjusted according to the diameter of the actuator 1, so that the V-shaped groove 26 on the fixed block 4 can clamp the outer side of the tail of the actuator 1. At the same time, the top of the clamping column 19 is pulled out of the clamping groove 23 by pulling the block 20, and the splint 12 on the movable block 11 can be moved so that the splint 12 is directly in front of the actuator 1. At the same time, the telescopic rod at the top of the actuator cylinder 1 can pass through between the splints 12, and then the servo motor 14 is started to drive the connecting rod 13 to control the rotation of the worm 25, and the worm 25 can drive the worm wheel 24 to rotate. The worm wheel 24 is connected to the rotating rod 10, and can drive the rotating rod 10 to rotate. The movable block 11 can be controlled to move through the rotating rod 10.
