[0030] The movable clamp 43 is fixedly connected to one end of the rotating rod 41. The movable clamp 43 and the fixed clamp 42 have the same curvature and are located inside the semi-circular ring 2. The distance from the movable clamp 43 to the collar is less than the distance from the fixed clamp 42 to the collar. Both the movable clamp 43 and the fixed clamp 42 are made of rubber and have patterns on their inner sides to increase friction.
[0031] The bottom end of the pin 44 passes through the middle of the rotating rod 41 to the top of the semi-circular ring 2, and the rotating rod 41 and the pin 44 are rotatably connected.
