The rotating shaft 42 is provided to limit the movement trajectory of the connecting rod 43. The inclined sliding block 47 is provided to slide on the inner wall of the sliding groove 46 to push the connecting rod 43 to perform a lever movement. The fixing mechanism 4 is provided to fix and limit the position of the rotor 3 inside the oil cylinder 2.

[0024] The above-mentioned snap mechanism 5 includes a snap slot 51, a fixed block 52, an inclined snap rod 53, a sliding shaft 54, a pull plate 55, and a reset spring 56.
