The top of the action plate 421 is fixedly connected with the back of the inner wall of the inner shell 1 through a spring. The right side of the action plate 421 is fixedly connected with an L-shaped bent plate 422, which is made of copper. The back of the L-shaped bent plate 422 is fixedly connected with a copper pad.
