The rotating part 3 is rotatably connected to the lower end surface of the connecting part 21, and the rotation axis of the rotating part 3 is parallel to the horizontal plane. A supporting block 31 is arranged at one end of the rotating part 3 close to the connecting part 21, and the rotating position of the rotating part 3 is located between the supporting block 31 and the sliding part 4. The upper end surface of the supporting block 31 is a rough plane.
