arranged in a surrounding way are fixedly connected on the inner wall of the limit sleeve 12, the push plates 13 are made of elastic metal, in the design, because the pipes to be processed have different specification models, and a single inner support rod 6 of the inner support component is only adapted to the pipe with a single inner diameter, when the pipes with different inner diameters are processed, the support rods with different outer diameters are replaced, at the moment, the connection between the bearing 5 and the inner support rod 6 also needs to be adapted to the inner support rods 6 with different outer diameters, in the design, after the inner support rod 6 is inserted into the round sleeve when the inner support rods 6 with different outer diameters are replaced, then the position limiting sleeve 12 is screwed, when the position limiting sleeve 12 is screwed, the push plates 13 are abutted against the inner wall of the conical groove and are bent under the driving of the inner wall of the conical groove, so that the clamping of the inner support rod 6 is completed by utilizing the plurality of push plates 13, the inner support rod can be adapted to the
