[0043] The inner diameter of the movable opening 23 is larger than the outer diameter of the lower end of the pressing pin 32, and the lower end of the pressing pin 32 extends into the movable opening 23;

[0044] The inner diameter of the movable opening 23 is larger than the outer diameter of the pressing pin 32, which can meet the needs of fine adjustment;
