Reinforcing steel bar bender

The utility model discloses a reinforcing steel bar bender which comprises a hanging hook 2, a bottom board 4 and a top piece 6. The center of the bottom board 4 is provided with an protrusion. A sliding groove 7 is arranged in the same axis of two sides of the protrusion in a symmetrical mode. The top piece 6 comprises a part which is arranged with the protrusion in a matched mode. One end of the hanging hook 2 is arranged in the sliding groove 7. Components of the reinforcing steel bar bender are detachable. Not only is construction cost saved, but also construction efficiency is improved. The reinforcing steel bar bender is suitable for meeting bending length requirements of reinforcing steel bars of various standards, can not only guarantee that bending angles of the reinforcing steel bars are consistent, but also guarantee that bending directions of the reinforcing steel bars are consistent, and therefore a goal of effectively guaranteeing quality of a reinforcing steel bar welding connector is achieved.
