The forceps handle 101 is an arc-shaped strip-shaped plate, and preferably, the forceps handle 101 is rotatably connected with the support rod 102. The through hole 203 is positioned in the middle of the top plate 201, the shape of the through hole 203 is matched with that of the magnetic pole key 3, and the area of the through hole 203 is slightly larger than the section of the magnetic pole key 3. The support arm 202 is used to support the support rod 102.
Furthermore, a plurality of saw-tooth-shaped protrusions 106 are arranged on the clamping plate 103. The serrations 106 serve to increase friction.
