Oval tube shaping grinding tool

The utility model relates to the field of grinding tools, in particular to an oval tube shaping grinding tool which comprises a grinding tool body, oval grooves are formed in the upper end and the lower end of the grinding tool body, the oval grooves transversely penetrate through the grinding tool body, and a roller inserting groove is formed in the middle of the grinding tool body. If more metal particles are attached to the surface of the adsorption magnetic block, an adjusting knob can be screwed clockwise to enable the movable cleaning ring to ascend to the highest position, the lower end of the movable cleaning ring is flush with the lower end of an oval groove, then a guide sliding block can be manually pushed, and the guide sliding block and the movable cleaning ring move from the front side to the rear side; and when the movable cleaning ring moves to the rear side position, metal particles adsorbed on the surface of the adsorption magnetic block can be scraped out to the outer side of the adsorption
