[0055] As a preferred embodiment, the support structure is provided in two sets, with the support structures respectively located on both sides of the fixing ring 205.

[0056] Working principle: In use, the operator first places one end of the metal pipe between rotating wheel 302 and rotating wheel 305. Rotating wheel 305 slides upward on the sliding groove 303 according to the size of the metal pipe. Rotating wheel 305 drives the bracket 304 to slide upward on the limiting rod 306 and simultaneously compresses the spring 307. Thus, the rebound of spring 307 keeps rotating wheel 305 in contact with the metal pipe. Then, through the interaction between rotating wheel 302 and rotating wheel 305... The metal tube is rotated forward and pushed. When one end of the metal tube is under the grinding disc 212, the spring 210 rebounds, causing the grinding disc 212 on the limiting post 211 to adhere to the surface of the metal tube. Then, motor 207 is turned on, which drives sleeve 208 to rotate. Sleeve 208 drives limiting post 211 to rotate via slide groove 209. Limit post 211 drives grinding disc 212 to rotate and grind the surface of the metal tube. Then, motor 201 is turned on. Machine 1 201 drives the spur gear 202 to rotate, which in turn drives the external gear ring 203 to rotate on the limiting groove 204. The external gear ring 203 drives the grinding disc 212 on the motor 207 to rotate around the surface of the metal pipe, thus comprehensively grinding the metal pipe. This process thoroughly removes rust, oil stains, and other defects from the surface of the metal pipe, making the surface smoother and flatter, thereby improving the adhesion of the subsequent anti-corrosion coating to the pipe surface. Then, the metal pipe is pushed forward at a constant speed by the rotation of the first rotating wheel 302 and the second rotating wheel 305. When one end of the metal pipe is between the other set of the first rotating wheel 302 and the second rotating wheel 305, another operator pulls the metal pipe to one side at a constant speed for grinding. Then, the first operator prepares the next metal pipe and grinds the surface of the metal pipe according to the above operation. Furthermore, by compressing the second spring 307 and the first spring 210, it is suitable for grinding metal pipes of different diameters, improving adaptability.
