An inductive piece is installed on the connecting piece 2 corresponding to the body 1, which is not marked in the figure, to record the rotation data of the body 1.

[0044] For example, the auxiliary assembly 3 can be provided in the form of a sleeve 31, and the connecting piece 2 can be fixedly connected with a clamping ring 32 on the outer side, or the connecting piece 2 can be integrally formed with the clamping ring 32 on the side. The embedding groove 33 is provided on the inner side wall of the sleeve 31 corresponding to the clamping ring 32, and the size of the embedding groove 33 can match the size of the clamping ring 32, that is, the clamping ring 32 can be clamped in the embedding groove 33, and the displacement of the clamping ring 32 in the vertical direction and the horizontal direction is limited by the embedding groove 33, so that the clamping ring 32 can only rotate in the embedding groove 33.

[0050] In another example, the side of the sliding block 25 close to the push rod 35 is provided with an inclined surface, since the push rod 35 can only move in the vertical direction, the sliding block 25 can only move in the horizontal direction; when the push rod 35 abuts against the sliding block 25, the sliding block 25 drives the limiting block 23 to move away from the limiting hole 24 along the horizontal direction along with the movement of the push rod 35, thereby releasing the restriction on the connecting piece 2, so as to facilitate the removal of the connecting piece 2 from the body 1.

[0051] In the above embodiments, since the push rod 35 is provided, the push rod 35 can drive the sliding block 25 to move, the sliding block 25 drives the limiting block 23 to move, the limiting block 23 is pushed out of the connecting piece 2, the restriction on the connecting piece 2 is released, and the connecting piece 2 is removed from the body 1, thereby facilitating the replacement or maintenance of the connecting piece 2.
