The surface of the sliding seat 22 is fixedly connected with a clamping block 23.
[0023] When chamfering and polishing the sleeve, the sleeve is placed in the middle of the sliding seat 22, and under the action of the tension of the tension spring 20, the clamping block 23 on the sliding seat 22 abuts against the outer wall of the sleeve and clamps and fixes the sleeve. After the sleeve is fixed, the rack 14 is driven to slide in the first sliding groove 13 by the push rod 19, so that the port of the sleeve is close to the polishing head 8, and the inner wall of the port of the sleeve abuts against the outer wall of the polishing head 8, so as to facilitate the subsequent chamfering and polishing.
[0024] The working principle and use process of the utility model are as follows:
