The movable block 12 is correspondingly set with the lead screw 10. The outer wall of the movable block 12 is slidably connected to the inner wall of the sliding groove 11. The movable block 12 is located inside the sliding groove 11. The side of the movable block 12 is connected to the connecting plate 21 by bolts.
