The first connecting column 109 is located at one end of the limiting tube cavity 104 and is fixedly connected to a first magnetic plate 111. When the first electromagnet 108 is started, it can attract the first magnetic plate 111, thereby driving the first connecting column 109 and the first elastic limiting plate 112 to move toward the axial direction of the first limiting cavity 107, thereby driving the first elastic limiting plate 112 to fix the connected circuit.
