[0002] Rebar is a steel strip, for example, in reinforced concrete, it is used to support the skeleton of the structure. Deformed steel bars have a greater bonding ability with concrete due to their auxiliary effect, and can therefore better withstand the effects of external forces. Rebars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. During the construction process, the rebars are bent due to actual construction needs. When the rebars are bent, due to their elasticity, they will rebound at a certain angle.

When the existing common steel bar bending restoration degree detection device is used to detect and clamp the steel bars, it generally has only one clamping structure, and the clamping of the steel bars may not be stable enough, which may affect the accuracy of the steel bar restoration degree detection.
