When in use, the end of the steel bar is inserted between the lower arc plate and the upper arc pressure plate through the correction sleeve, and the threaded push rod is turned downward to make the upper arc pressure plate press the end of the steel bar, so as to prevent the steel bar from being damaged when the steel bar is straightened during road and bridge construction. When the correction force of the correction sleeve is reached, it slips out from the lower arc plate and the upper arc pressure plate, and the cylinder is started to push the correction sleeve to move. When the correction sleeve moves, it corrects the steel bar from the fixed end of the steel bar, so that the steel bar moved by the correction sleeve changes shape and the steel bar is straightened. The inner diameter of the inner hole of the correction sleeve changes from large to small, so that the correction has a transition process, which prevents damage to the steel bar when the steel bar is straightened during road and bridge construction. The minimum diameter inside the correction sleeve is the diameter of the straightened steel bar. BRIEF DESCRIPTION OF THE DRAWINGS
