When the rectangular rod 8 moves to the square hole 12, the rectangular rod 8 that loses the extrusion force is reset under the action of the elastic force of the first spring 10 itself. At the same time, the L-shaped block 3 moves downwards to drive the pressing block 5 to move downwards, and the bottom of the pressing block 5 contacts the top of the ejector rod 15. Under the action of the lever, the other side of the pressing block 5 presses and fixes the plate body 4. When the plate body 4 needs to be disassembled, the two vertical plates 9 are pinched, and the rectangular rod 8 slides out of the square hole 12.
