[0030] The surface of the threaded rod 402 is threadedly provided with a threaded sleeve 403, the bottom surface of the threaded sleeve 403 is symmetrically provided with a connecting rod 404, the connecting rod 404 is connected with the fixed plate 401, the bottom surface of the connecting rod 404 is fixedly connected with a connecting plate 405, the bottom surface of the connecting plate 405 is fixedly connected with a friction block 406, the side surface of the threaded rod 402 close to the top is connected with a pinion 407, the side surface of the pinion 407 is meshingly connected with a main gear 408, the side surface of the main gear 408 away from the pinion 407 is fixedly connected with a rotating rod 409, the rotating rod 409 is connected with the body 1, and the top surface of the threaded rod 402 is rotatably connected with the groove 3, as shown in Figures 2-4As shown, rotating the rotating rod 409 drives the main gear 408 to rotate, which in turn drives the driven gear 407 to rotate, which in turn drives the threaded rod 402 to rotate, which in turn drives the threaded sleeve 403 to move. The threaded sleeve 403 is fixedly connected to the connecting rod 404, which is slidably connected to the fixing plate 401. The cooperation between the connecting rod 404 and the fixing plate 401 limits the movement of the threaded sleeve 403, allowing it to move on the threaded rod 402.
