A limiting groove 27 is provided on the surface of the rotating ring 26. When the pressing ring 23 is pressed downward, the arc surface of the contact block 24 will contact the inclined surface of the linkage block 29, so that the contact block 24 gradually contacts and pushes the linkage block 29 to rotate, so that the linkage block 29 drives the rotating ring 26 to rotate together, and the limiting rod 28 will move relatively along the limiting groove 27, and the inner side of the limiting groove 27 is slidably connected to the limiting rod 28, and the bottom surface of the limiting rod 28 is fixedly connected to the inner wall of the connecting disk 21, and the side of the linkage block 29 close to the rotating ring 26 is connected to the rotating ring 26. The outer side of the moving ring 26 is fixedly connected, and the surface of the linkage block 29 is fixedly connected with an arc spring 210. The limit groove 27 ensures that the rotating ring 26 will not deviate when rotating. At the same time, the linkage block 29 will be compressed after being resisted and rotated.
