When tightening, the rotating rod 17 can rotate along the curvature of the leaf spring, reducing the wear of the leaf spring by the rotating rod 17; symmetrically distributed empty slots 18 are provided on one side of the top of the workbench 1 close to the card slot 14, and evenly distributed positioning holes 19 are provided on the lower surface of the inner wall of the empty slots 18. There are four positioning holes 19 in each of the two empty slots 18, so that the support block 193 can be adjusted to a variety of different distances, thereby improving the user experience; the internal movable cards of the two empty slots 18 are provided with movable plates 191, and the tops of the two movable plates 191 are jointly fixed with a connecting plate 192, and the tops of the connecting plates 192 are provided with symmetrically distributed support blocks 193, and the tops of the two movable plates 191 are penetrated by latches 194, which are used in conjunction with the positioning holes 19.

[0017] A rotating shaft 2 is rotatably mounted on the lower surface of the inner wall of the connecting plate 192 , and a gear 21 is fixedly sleeved on the outer side of the rotating shaft 2 . The outer side of the gear 21 is meshedly connected with two diagonally distributed tooth plates 22 , and the two tooth plates 22 are fixedly connected to the corresponding support blocks 193 , respectively.

[0018] A worm wheel 3 is provided on the top fixed sleeve of the rotating shaft 2, and a worm 31 is meshingly connected to the outer side of the worm wheel 3. The worm 31 is driven to rotate the worm wheel 3, so that the worm wheel 3 drives the rotating shaft 2 to rotate. At the same time, the worm wheel 3 and the worm 31 can self-lock the rotating shaft 2 to prevent the rotating shaft 2 from rotating on its own.

[0019] A fixing plate 4 is fixedly installed on the top of the connecting plate 192. The worm 31 rotates and passes through the fixing plate 4. The fixing plate 4 is in contact with the support block 193. By setting the fixing plate 4, the worm 31 can be supported so that it can rotate smoothly. At the same time, the fixing plate 4 can share a certain pressure for the support block 193, thereby improving the service life of the support block 193.

[0020] A pad 5 is fixedly installed on one side of the top of the workbench 1 close to the hydraulic rod 13, and the hydraulic rod 13 is fixedly installed on the top of the pad 5.

[0021] A symmetrically distributed stabilizing plate 6 is fixedly installed at the bottom end of the movable plate 11, and a symmetrically distributed stabilizing groove 61 is opened at the top of the workbench 1. The stabilizing plate 6 is movably clamped in the stabilizing groove 61. By setting the stabilizing plate 6 and the stabilizing groove 61, the stability of the movable plate 11 during movement is improved.

[0022] Working principle: In actual use, the support block 193 is driven to move by pushing the connecting plate 192, and the movable plate 191 is driven to move in the empty slot 18 at the same time. When the support block 193 moves to the appropriate position, the latch 194 passes through the movable plate 191 and is stuck in the positioning hole 19, so that the latch 194 fixes the movable plate 191, and then the threaded rod 15 is driven to rotate to drive the clamping block 16 and the rotating rod 17 to move. When it moves to the appropriate position, the leaf spring is placed between the connecting plate 192 and the movable plate 11, and the hydraulic rod 13 is driven so that its output end drives the movable plate 11 and the pressure plate 12 to move until the pressure plate 12 presses the leaf spring; the gear 21 is driven to rotate by the driving shaft 2, and the gear 21 drives the two tooth plates 22 to move toward each other, and the two tooth plates 22 drive the support blocks 193 fixedly connected to each other to move toward each other, so that the distance between the two support blocks 193 can be adjusted to adapt to leaf springs of different sizes.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
