[0029] As a further implementation of the present invention, two arc plates 7 and two polishing layers 4 are provided, and the arc plates 7 and the polishing layers 4 correspond to each other one by one. The arc plates 7 are arranged on the upper and lower sides of the transmission shaft 2, and the positions between the two ends of the arc plates 7 are connected by the first spring telescopic rod 5. The arc plates 7 and the transmission shaft 2 have the same axis, and the end of the arc plates 7 away from the transmission shaft 2 and the end of the moving block 31 away from the transmission shaft 2 are arranged in the same plane. Through the above arrangement, the arc plates 7 can stably support the polishing layer 4, and at the same time, the polishing layer 4 can be driven to rotate stably during the rotation of the rotating shaft 2.

[0030] As a further implementation of the present invention, a first limiting hole 9 is provided on the side of the transmission shaft 2 away from the driving motor 1, and the center points of the first limiting hole 9 and the guide block 61 are arranged on the same vertical line.

[0031] As a further implementation of the present invention, a second limiting hole 10 is provided on the side of the transmission shaft 2 away from the driving motor 1, and the center points of the second limiting hole 10 and the moving block 31 are arranged on the same vertical line.

At the same time, it can polish steel pipes with different inner diameters within a certain range, and has a wider range of applications. After the polishing is completed, water is flushed into the inside of the steel pipe to treat the residue produced by the polishing, that is, it can be cleaned after completion.
