An elastic rod 8 is arranged between the fixed block 6 on the same side and the middle part of the movable block 2 7. The front and rear ends of the opposite surfaces of the two groups of movable blocks 2 7 are both provided with connecting rods 3 11 through the rotating shaft seat. The close ends of the front and rear connecting rods 3 11 are connected by bolts, and an L-shaped block 13 is sleeved on the top of the outer wall of the bolt. The two groups of L-shaped blocks 13 are longitudinally inserted with screw rods 14, and a turntable 15 is arranged on the front side of the screw rods 14.
[0016] like Figure 1 As shown, the elastic rod 8 includes a limiting cylinder 81 connected to one side of the opposite surface of the two groups of fixed blocks 6 and a movable rod 82 connected to one side of the back of the two groups of movable blocks 7. The movable rod 82 is movably inserted in the limiting cylinder 81. The outer wall of the movable rod 82 is sleeved with a compression spring 83 to prevent the movable block 7 from being unevenly stressed and the displacement of the movable blocks 7 on the left and right sides from being deviated.
[0017] like Figure 2 As shown, the opposite sides of the front and rear L-shaped blocks 13 are both provided with threaded holes matching the screw rod 14, and the threaded holes are rotated in opposite directions, and the L-shaped blocks 13 are moved in opposite directions at the same time by rotating the screw rod 14;
