At least one of the annular magnet first magnetic attraction piece, annular magnet second magnetic attraction piece part or all is a magnet. Can, first magnetic attraction piece, second magnetic attraction piece are magnets. The magnetic pole of the magnet, the strength of the magnetism, can be selected or adjusted as needed, as long as the first magnetic attraction piece, second magnetic attraction piece can be magnetically attracted to rotate. Also. One of the annular magnet first magnetic attraction piece, annular magnet second magnetic attraction piece is a magnet, and the other is a metal piece.

[0023] Regarding the first magnetic attraction piece 3

[0024] The top end of the annular magnet first magnetic attraction piece is cylindrical. Preferably, the top end of the annular magnet first magnetic attraction piece is cylindrical. To make the rotation between the first magnetic attraction piece and the second magnetic attraction piece more smooth. Scheme 1: The annular magnet first magnetic attraction piece is cylindrical as a whole, and the annular magnet first magnetic attraction piece is bonded to the connecting part. Scheme 2: The outer diameter of the top end of the annular magnet first magnetic attraction piece is smaller than the outer diameter of the bottom end of the annular magnet first magnetic attraction piece, so that the first magnetic attraction piece is "T" shaped. In turn, the larger bottom end is better fixed on the part, thereby effectively preventing it from falling off the part. Under this scheme, the bottom end of the annular magnet first magnetic attraction piece can be bonded to the connecting part or directly embedded in the part. Scheme 3: As shown in Figure 2 , the annular magnet first magnetic attraction piece includes a positioning tube 9 in the shape of "T", and an annular magnet 7 in the shape of a ring is sleeved on the annular magnet positioning tube 9. One end of the annular magnet positioning tube 9 is provided with an end cap, and an opening hole is opened on the annular magnet positioning tube 9, the opening hole facing away from the end cap, so as to connect the part by the opening hole. The annular magnet opening hole can be internally threaded, or the end of the annular magnet positioning tube away from the annular magnet end cap can be provided with external threads. To achieve threaded connection between the first magnetic attraction piece and the part. An annular protective ring 8 can be provided between the annular magnet and the positioning tube. The protective ring has two functions: one is to adjust the size of the inner diameter of the annular magnet, thereby adjusting the thickness of the annular magnet, and further adjusting the strength and cost of the magnetic circuit, by changing the outer diameter of the annular magnet. The other is to increase the friction between the positioning tube and the annular magnet, preventing relative sliding between the two. The annular magnet protective ring is preferably a rubber ring. Under scheme 3, the height of the positioning tube, the rubber ring and the annular magnet can also be set, so that a gap is formed between the end cap and the annular magnet, the second magnetic attraction piece is clamped by the gap, and the first magnetic attraction piece is prevented from falling out of the second magnetic attraction piece.

[0025] Regarding the second magnetic attraction piece

The inner contour of the second opening is preferably matched with the outer contour of the second magnetic attraction part. Preferably, the inner contour of the cross section of the second magnetic attraction part of the annular magnet is circular in shape, so as to reduce the production difficulty. Preferably, the outer contour of the cross section of the second magnetic attraction part of the annular magnet is polygonal in shape, so as to prevent the second magnetic attraction part from rotating when the second magnetic attraction part is used on the component. The second magnetic attraction part of the annular magnet can be directly embedded in the component two. Alternatively, an annular groove with an inward opening is arranged on the inner side wall of the second opening of the annular magnet, and the second magnetic attraction part of the annular magnet is fixed or clamped in the annular groove of the annular magnet.

Thus, the rotation of the first magnetic attraction part and the second magnetic attraction part is smoother by using the bearing. The second magnetic attraction part of the annular magnet can be directly used as the side wall of the bearing. Thus, the structure is simplified. For the bearing with a metal material outer wall, the second magnetic attraction part can not be separately arranged, and the outer wall of the bearing can be directly used as the second magnetic attraction part.

[0028] Alternatively, a plating layer is arranged on the outer wall of the first magnetic attraction part of the annular magnet and the inner wall of the second magnetic attraction part. Thus, the plating layer can improve the wear resistance or reduce the friction coefficient.
