After magnetization is completed, when the NdFeB magnet is taken out from the inside of the equipment, the electric telescopic rod 10 is started, and the output end of the electric telescopic rod 10 is used to drive the connecting plate 11 to move, so that the inclined groove inside the connecting plate 11 is used to drive the lifting seat 16 to move upward through the connecting shaft 12, thereby driving the NdFeB magnet on the top of the bottom plate 17 to separate from the inside of the holding platform 5. While the lifting seat 16 moves, the card ball 14 is squeezed through the support plate 8 and drives the spring 15 to compress. When the lifting seat 16 has finished moving, the rebound force of the spring 15 is used to push the card ball 14 to move to the groove inside the support plate 8, and the card ball 14 is fixed by the groove inside the support plate 8, thereby enhancing the stability of the lifting seat 16 and improving the efficiency of removing the NdFeB magnet.
