[0028] In use, first, during the fixation of the flange, the flange hole to be cleaned is first inserted into the interior of the second limiting rod 17, so that the second limiting rod 17 can be used to fix and limit the flange hole. After the limiting hole is limited by the second limiting rod 17, the first motor 15 is started to operate. The first motor 15 drives the elliptical driving block 16 to rotate, and then the driving block 16 can be used to drive the connecting block 14 and the fixing plate 9 to expand outward along the moving groove 3, so that the inner wall of the flange can be tensioned and fixed. After the processing and cleaning are completed, the provided first spring 13 can push the fixing plate 9 to reset, so as to facilitate the removal of the flange.

When the telescopic mechanism 7 drives the cleaning mechanism 8 to move downward, the cleaning rubber roller 19 can be extended into the interior of the flange hole, and two groups of cleaning rubber rollers 29 will first contact the second limiting rod 17. When the cleaning rubber roller 29 continues to descend, it can push the second limiting rod 17 and the second mounting plate 18 to descend away from the interior of the flange hole, so as to prevent the second limiting rod 17 from affecting the cleaning of the flange hole. After the cleaning rubber roller 29 extends into the flange hole, the second motor 27 is started to operate.
