Example 3:

the difference from embodiment 1 or embodiment 2 is that: the connection between the magnet ring 12 and the cylinder 22 is different.

Referring to fig. 8 and 9, a locking groove 2231 is formed in a side wall of the fixing groove 221, the locking groove 211 and the fixing groove 221 are perpendicular to each other, a first spring 2233 and a locking block 2232 are installed in the locking groove 211, one end of the first spring 2233 is fixed to a groove bottom wall of the locking groove 211, the other end of the first spring 2232 is fixed to the locking block 2232, and one end of the locking block 2232, which is far away from the first spring 2233, extends out of the locking groove 2231. A clamping groove 121 corresponding to the locking block 2232 is formed in the magnetic ring 12, and one end of the locking block 2232, which is far away from the first spring 2233, is inserted into the clamping groove 121. A second spring 2211 is fixed to the bottom wall of the fixing groove 221, and one end of the second spring 2211, which is far away from the bottom wall of the fixing groove 221, abuts against the magnet ring 12. When the locking block 2232 is disconnected from the locking groove 121, the second spring 2211 pushes the magnetic ring 12 out of the fixing groove 221 by the resilience force of the second spring 2211. In order to facilitate the separation of the locking block 2232 from the locking groove 121, a mounting hole 222 is formed in the side wall of the cylinder 22, the mounting hole 222 and the locking groove 2231 are perpendicular to each other, and the driving rod 2221 is inserted into the mounting hole 222. A slanted slot 2234 is formed on one side of the locking block 2232 facing the driving rod 2221, and an inclined surface of the slanted slot 2234 is inclined downward from the first spring 2233 toward the second spring 2211. In order to facilitate the installation of the magnetic ring 12, an auxiliary installation slope 2235 is formed on one end of the locking block 2232 away from the first spring 2233 and one side of the locking block 2232 away from the second spring 2211.

The implementation principle of the embodiment 3 is as follows: when the magnetic ring 12 is detached, the driving rod 2221 is firstly inserted into the mounting hole 222, when the driving rod 2221 abuts against the locking block 2232, the driving rod 2221 continues to apply a pushing force, the driving rod 2221 slides along the inclined surface of the inclined groove 2234, so that the locking block 2232 is gradually separated from the slot 121, and when the locking block 2232 is completely separated from the slot 121, the second spring 2211 ejects the magnetic ring 12 out of the fixing slot 221 through the self resilience force.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
