The annular upper end cover 1 and the annular lower end cover 3 are both magnetically conductive metals, and the core shaft 2 is made of magnetically shielding material. The core shaft 2 includes a sleeve 20 and an annular step 21 connected to the periphery of the sleeve 20. The annular upper end cover 1 and the annular lower end cover 3 are respectively fitted onto the two ends of the sleeve 20. The annular magnet 4 is fitted onto the annular step 21. The annular upper end cover 1 and the annular lower end cover 3 are respectively adsorbed onto the two end faces of the annular magnet 4.

[0023] Its working principle is as follows: During assembly, first, the annular upper end cap 1 is assembled onto one end of the sleeve 20. Then, the annular magnet 4 is fitted onto the annular step 21 and attracted to the inner end face of the annular upper end cap 1. The magnetic shielding ring 5 is then fitted onto the annular magnet 4. Next, the annular lower end cap 3 is assembled onto the other end of the sleeve 20. The two ends of the annular magnet 4 will be attracted to the annular upper end cap 1 and the annular lower end cap 3, respectively. If the end of the annular magnet 4 closer to the annular upper end cap 1 is the N pole and the end closer to the annular lower end cap 3 is the S pole, the magnetic... The magnetic field lines will pass from the N pole of the annular magnet 4 through the upper annular cover 1 and the lower annular cover 3 into the S pole of the annular magnet 4. The magnetic field lines will not pass through the spindle 2 and the magnetic isolation ring 5, which can reduce magnetic loss and improve the utilization rate of magnetism. When the upper annular cover 1 and the lower annular cover 3 are attached to the magnetic conductive metal surface, they have a better magnetic attraction effect.
