[0002] Concrete beams, columns or floor panels require a large amount of steel bars, and the ends of the steel bars mostly need to be bent to strengthen the anchoring force. The traditional bending method is to weld the vertical bending columns on the iron table, manually clamp the ends of the steel bars between the bending columns, and then bend the steel bars to bend the ends. This construction is still applicable to steel bars with a small number, small diameter and low strength. For steel bars with a large number, large diameter and high strength, the traditional method has high labor intensity and low construction efficiency. It is obviously not competent, and often requires the use of a steel bar bending machine for bending.

[0003] Some steel bars or wires have curvature before bending, and the feeding device of a general bending machine cannot straighten the steel bars. Therefore, workers are required to straighten them in advance, resulting in low work efficiency. Summary of the invention

[0017] Furthermore, the clamping roller group 4 includes a clamping roller 401 and a mounting cylinder 403 arranged at both ends of the clamping roller 401, and the two ends of the clamping roller 401 are respectively provided with a connecting piece 405 connected with a thread, and the connecting piece 405 is slidably connected with the inside of the mounting cylinder 403.
