An air inlet 122 communicating with the inside of the air supply cavity 121 is provided on the side wall of the fixing blocks 12. An air pipe connector is provided on the outside of the air inlet 122. The air pipe connector can be connected to an external air supply device through an air pipe. Under the push of air pressure, it can drive the push plate 123 to move, thereby driving the connecting rod 124 and the positioning plate 125 to move. With the cooperation of the two positioning plates 125, the plate material is clamped and fixed, which is convenient and quick.

[0023] It should be noted that a spring 126 is fixedly connected to the side of the push plate 123 near the connecting rod 124. The other end of the spring 126 is connected to the inner wall of the fixing block 12. When the push plate 123 moves toward the connecting rod 124, it can squeeze the spring 126.
