The connecting spring 204 is located on one side of the fixed cylinder 203 and is fixedly connected to a push rod 206 on its outer wall away from the button 202.

[0036] The button 202 drives the connecting spring 204 to move, and the connecting spring 204 drives the push rod 206 to move;

[0037] A corresponding hole 205 is formed through the other end of the fixing tube 203, and a limiting ball 207 is connected to the inner wall of the corresponding hole 205 in a limited sliding manner;
