Wherein, the blocking member surrounds and connects the bottom end to form a column shape, and the positioning portion is in communication with the open end.

Wherein the magnetic element is placed in the positioning portion by the open end and is engaged with the bottom end, and the magnetic element is aligned with the blocking member.

Further, a first stop member, a second stop member and a third stop member respectively extend from the bottom end to the open end, wherein the first stop member, the second stop member and the third stop member They are spaced apart from each other and have a triangular shape.

Wherein the magnetic element is in a cylindrical shape, and a surface of the first blocking member adjacent to the positioning portion is a first inner surface, and a surface of the second blocking member adjacent to the positioning portion Is a second inner surface, the surface of the third blocking member adjacent to the positioning portion is a third inner surface, and the first inner surface, the second inner surface and the third inner surface are Arc surface.
