[0028] The limiting structure 54 includes a follower plate 541. The end of the rotating rod 53 is integrally formed with an anti-skid tooth 531. The follower plate 541 is connected to the rotating rod 53 and connected to the anti-skid tooth 531, thereby improving the effect of synchronous rotation. The follower plate 541 is provided with a limiting groove 542.

[0029] The upper end of the cushion block 1 is provided with a screw rod 543 threadedly connected thereto, the screw rod 531 is located at the upper end of the follower plate 541, and the lower end of the screw rod 543 is provided with a pressing block 544 rotatably connected thereto, the pressing block 544 is fitted with the inner surface of the cushion block 51, and the pressing block 544 can be slidably connected to the cushion block 51 in a vertical state, and the pressing block 544 can be limited to prevent the pressing block 544 from rotating with the screw rod 543, and a limiting block 545 is provided on the end surface of the pressing block 544, and the limiting block 545 can be plugged into the limiting groove 542;
