Figure 1 As shown, the strong magnet 11 is a hollow cylinder, and the diameter of the hollow cylinder of the strong magnet 11 decreases from right to left. When the strong magnet 11 is on the left side of the hollow cylinder, the diameter of the central control cylinder is the same as the diameter of the magnet fixing hole 13. The strong magnet 11 is two symmetrical settings, and the strong magnet 11 is fixed to the magnet fixing point by the matching of the screw and the thread.
