[0021] The circular ring 12 can only rotate in the circular ring groove 14 and cannot move in other directions in the circular ring groove 14, which is used to make the rotating tube 11 and the pressing tube 13 rotate relatively, and when the rotating tube 11 moves left and right, the pressing tube 13 can also be driven to move left and right through the circular ring 12.
[0022] The limiting pieces are used to limit the movement track of the pressing tube 13, so that it can only move left and right.
[0023] Specifically, the limiting pieces comprise a sliding block 15, the sliding block 15 is fixedly installed on the inner side wall of the pressing tube 13, and the outer side wall of the protective tube 2 is provided with sliding grooves 16 at the upper and lower ends.
