The other end of the driving motor 36 is connected to one end of the connecting shaft 34. The surface of the power connection line 37 is adapted to the inside of the wiring component 5. The wiring component 5 includes a connecting seat 51, a first limiting frame 52 and a second bearing 53. The middle of the upper surface of the connecting seat 51 is fixed. A first limit frame 52 is connected, and two second bearings 53 are symmetrically inlaid and installed on the surface of the first limit frame 52 along the center. The lower surface of the connecting seat 51 is connected to the side wall of the electromagnet 4. The connecting seat 51 is made of an iron component.
