[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a wound nylon polishing brush includes a rotating shaft 1 and a metal winding strip 3. A sleeve assembly is sleeved on the rotating shaft 1. The sleeve assembly is formed by splicing multiple mounting sleeves 8. The number of metal winding strips 3 is the same as the number of mounting sleeves 8. The metal winding strip 3 has a rectangular strip structure. Several brush filaments 2 are fixedly installed on one side wall of the metal winding strip 3. The brush filaments 2 are made of nylon. The side wall of the metal winding strip 3 away from the brush filaments 2 is wound around the outer surface of the mounting sleeve 8. The multiple mounting sleeves 8 are connected by a fixing mechanism, which consists of a connecting rod 4, a fixing plate 5, and a nut 7.

[0021] The two ends of the metal winding strip 3 are welded to the outer surface of the mounting sleeve 8.

[0022] There are two connecting rods 4. The rear end of the connecting rod 4 is fixedly connected with a nut. The outer surface of the front end of the connecting rod 4 is provided with an external thread 6. The front end of the connecting rod 4 is also fitted with a nut 7 that is threaded with the external thread 6. Two through holes 9 are provided on the side wall of the mounting sleeve 8. The through holes 9 are slidably fitted with the connecting rod 4. The fixing plate 5 is fitted onto the outer surface of the rotating shaft 1 and fixedly connected to the rotating shaft 1. The fixing plate 5 is provided with mating holes at the extension positions of the two through holes 9.

[0023] In use, the mounting sleeve 8 is placed on the rotating shaft 1, and then the through holes 9 on all the mounting sleeves 8 are aligned with the mating holes on the fixing plate 5. Next, the connecting rod 4 is inserted into the through holes 9 and the mating holes in sequence. Then, the nut 7 is rotated and installed on the front end of the connecting rod 4. With the nut at the rear end of the connecting rod 4, all the mounting sleeves 8 can be locked together.

[0024] Two limit keys 10 are fixedly installed on the outer wall of the rotating shaft 1, and two keyways 11 are opened on the inner wall of the mounting sleeve 8. The keyways 11 slide and engage with the limit keys 10.
