Novel thin-wall roller surface sinking pit holding and pulling device

The invention discloses a novel thin-wall roller surface sinking pit holding and pulling device which comprises a base plate, a holding and pulling rod, a supporting plate, a bending plate, a hoistingring and a sinking pit roller, the base plate is positioned at the position, where sinking pits exist, of the sinking pit roller, the supporting plate is positioned through a positioning stud on thebase plate, the supporting plate and the base plate are connected in a fastened manner through a fastening nut, and the bending plate is connected with the supporting plate in a fastened manner through a bolt and a nut. According to the novel thin-wall roller surface sinking pit holding and pulling device, the sinking pits caused by damage to the thin-wall roller surface are repaired through holding and pulling, the roller is repaired through one time (or multiple times) of holding and pulling, the problem about environment pollution generated by direct plating repairing is reduced, the problem that the repairing effic
