Wire holes are opened at both the upper and lower ends of the movable plate. Both ends of the elastic wire pass through the wire holes and are fixed to the tail end of the movable rod.
[0005] In a specific embodiment of this utility model, the fixing seat is welded to the surface of the protective cover, and the elastic thread is attached to the surface of the fixing strip.
[0006] In a specific embodiment of this utility model, the upper and lower ends of the fixed base are respectively provided with limiting holes, and the upper and lower ends of the movable plate are respectively provided with limiting rods, which pass through the limiting holes.
[0007] In a specific embodiment of this utility model, the two sets of electrode balls are arranged on the same axis.
