[0030] Lifting blocks 8, there are two lifting blocks 8, which are respectively movably set in the lifting grooves 9 opened on the left and right inner walls of the material rack body 1. The lifting grooves 9 are rotatably connected to the lead screws 10 through bearings. The lifting blocks 8 are rotatably sleeved on the lead screws 10 through threads.

The guide blocks 17 can provide auxiliary guidance for the movement of the lifting frame 11 in the material rack, thereby improving the movement stability of the lifting frame 11.

[0031] The first adjusting rod 13 is rotatably inserted into the left side wall of the material rack body 1 via a bearing. One end of the first adjusting rod 13 is connected to the lead screw 10 on the left side via a bevel gear pair.

Movable blocks 12-2 are threadedly mounted on the bidirectional lead screws 12-3. Second adjusting rods 12-4 are inserted into the left and right sides of the front of the lifting frame 11 via bearings. The second adjusting rods 12-4 are fixedly connected to the front ends of the bidirectional lead screws 12-3. Rotation of the bidirectional lead screws 12-3 allows for synchronous reverse movement of the movable blocks 12-2 on both sides.

Then, the first adjusting rod 13 is rotated. The first adjusting rod 13 drives the left lead screw 10 to rotate through the bevel gear pair. With the transmission of the first synchronizing rod 14, the lead screws 10 on both sides are rotated synchronously. When the lead screw 10 rotates, it can drive the lifting block 8 to move downward. The lifting block 8 can drive the lifting frame 11 to move downward. The lifting frame 11 drives the pressure plate 2 to move downward through the position adjustment mechanism 12, so that the pressure plate 2 abuts against the workpiece, thereby achieving the clamping and fixing of the workpiece by the pressure plate 2.
