Construction materials are frequently used in construction sites and civil engineering sites, and reinforcing bars are often used as construction materials. These reinforcing bars are often cut or bent to an appropriate standard according to the purpose of use. Accordingly, a reinforcing bar cutter for automatic cutting of reinforcing bars and a reinforcing bar bending machine for automatically bending reinforcing bars have been developed and used.

The technology related to the reinforcing steel bending machine is disclosed in Korean Registered Patent Publication No. 10-0344128 entitled " safety reinforcing steel bending machine ", and Japanese Patent Application Laid-Open No. 10-2004-0061196 entitled "multipurpose reinforcing steel bending machine ".

In the above-mentioned reinforcing bar bending machine, a reinforcing bar bent in a reinforcing bar portion of a reinforcing bar is inserted, and the bending switch operates so that the bending roller moves while rotating along the guide groove to bend the reinforcing bar with a strong force.

Thus, when the bending roller is bent, the bending roller bends the reinforcing bar inserted in the reinforcing bar portion of the reinforcing bar while performing the circular motion, and once the bending switch is operated, the bending bar is completely bent by the set angle and returned to the original position. Returning to the home position of the bending roller is performed by the elastic force of the chain connected to the elastic spring. In the past, elastic force for returning the bending roller to the home position has not been sufficiently secured, and the return of the bending roller to the home position is often unstable.

Also, the reinforcing bars having the reinforcing bars are sometimes replaced in the process of using the reinforcing bars. In the past, there has been a problem that the replacement of the reinforcing bars is troublesome.
