In this embodiment, the magnetic attraction between the fixing body 1 and the fixing fitting 2 is achieved by a first magnet 1-8 provided on the fixing body 1 and a second magnet 2-3 provided on the fixing fitting 2. In some embodiments, a magnet may be disposed on one of the fixing body 1 and the fixing fitting 2, and a ferromagnetic member may be disposed on the other, which may also have a similar magnetic attraction effect.

Referring to fig. 3 and 4, the fixing fitting 2 has a circular ring structure, the fixing inclined position 2-1 is formed on the circular ring surface of the fixing fitting 2, a positioning notch 2-2 is arranged on the inner side of the circular ring of the fixing fitting 2, and a positioning protrusion 1-2 matched with the positioning notch 2-2 is arranged on the fixing main body 1; rotation between the fixing body 1 and the fixing fitting 2 is prevented by the cooperative positioning of the positioning projection 1-2 and the positioning notch 2-2. In some embodiments, the fixing fitting 2 may also be a rectangular ring, an elliptical ring, or other ring-like structures; the present embodiment is not limited.
