A damping mechanism 8 is provided on the movable seat 6. Two symmetrically distributed screws 9 are mounted inside the rotating frame 2 via bearings. A synchronous wheel 10 is fixedly connected to the upper outer side of the screws 9. Two symmetrically distributed threaded tubes 12 are fixedly connected to the outer side of the lower pressure frame 4.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The side plate frame 7 is slidably connected to the lower pressure frame 4, and the movable seat 6 is slidably connected to the lower pressure frame 4. The side plate frame 7 can limit the side plate of the plate-shaped workpiece. The screw 9 is connected to the support frame 3 through a bearing. The outer side of the synchronous pulley 10 is fitted with a synchronous belt 11. The synchronous belt 11 can drive the two screws 9 to rotate simultaneously through the synchronous pulley 10. The lower end of the screw 9 is fixedly connected to a knob 13. The screw 9 is connected to the threaded tube 12 through a thread. The knob 13 can drive the screw 9 to rotate.

[0025] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 The damping mechanism 8 includes a fixed frame 81. The fixed frame 81 is fixedly connected to the front of the movable seat 6. A support plate 82 is slidably connected to the outside of the fixed frame 81. A rubber block 83 is fixedly connected to the side of the support plate 82 near the lower pressure frame 4. A spring 85 is provided on the outside of the fixed frame 81. The rubber block 83 can limit the side plate frame 7 through the friction between it and the lower pressure frame 4.

The handle 84 drives the support plate 82 and the rubber block 83 to move and compresses the spring 85. When the rubber block 83 is disengaged from the lower pressure frame 4, the moving seat 6 can be pushed to move. The moving seat 6 drives the side plate frame 7 to move. After the side plate frame 7 contacts the plate-shaped workpiece, the handle 84 is released, and the spring 85 returns to its original position. The spring 85 can use its elasticity to drive the rubber block 83 to press against the outside of the lower pressure frame 4, thus completing the stable positioning of the plate-shaped workpiece.
