as a further improvement of the utility model, the connecting plate is fixedly connected with the nut through the supporting tube, and the stud also passes through the supporting tube; the support tube has the functions of supporting and guiding the stud, and the moving straightness can be improved;

as a further improvement of the utility model, the front limiting pipe is fixedly connected with the middle part of the mandrel, and two sleeves are sleeved at the two ends of the mandrel; the deformation of the pressure plate during rotation can be avoided;

as a further improvement of the utility model, a handle is fixedly arranged at one end of the stud, which is far away from the clamping groove; the stud is convenient to rotate;

to sum up, the utility model discloses be convenient for realize the whole strip processing of band steel groove, can improve machining efficiency to there is the corrective action to ceiling pipe wave deformation, can avoid letting the overproof of pipe breach position, improve the machining precision, do benefit to the assembly precision that the automatic welding of edge band steel ran the screen to weld and follow-up group is big to be shielded.
