The two mounting plates 1 5 are close to each other. The side is provided with a positioning groove 17, and the positioning block 10 is specifically plugged into the positioning groove 17. The positioning block 10 can be limited by the positioning groove 17, so that the positioning block 10 can quickly enter the mounting plate 1 5, and the installation speed of the clamp 6 can be improved. The interior of the mounting plate 1 5 is fixedly connected with a compression spring 11, and the other end of the compression spring 11 is fixedly connected with a card block 12, and the card block 12 and the fixed The positioning block 10 is in contact with the positioning block 10, and a slot 13 is provided in the middle of the positioning block 10.
