[0052] Finally, the movement of the mounting plate 302 drives the third screw 318 to move, and the movement of the third screw 318 drives the second gear 322 to move. When the second gear 322 and the third gear plate 323 are engaged, the second gear 322 is driven to rotate, and the rotation of the second gear 322 drives the third screw 318 to rotate. The rotation of the third screw 318 drives the moving block 317 to move, and the movement of the moving block 317 drives the connecting bar 503 to move.
