[0036] Through the above technical solution, the movement of the screw rod 203 drives the fixed sleeve 405 to move, and then drives the connecting plate 406 to move, and then drives the connecting rod 407 to move, and then drives the guide sleeve 403 to move on the surface of the guide rod 402, and then the spring four 404 is extended, thereby achieving the effect of guiding the screw rod 203 in the moving state.
