[0002] A fixture for metal processing of steel bars is a device for fixing steel bars. Steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars.

[0003] At present, steel bar processing is a common metal processing method, in which steel bars are processed into different shapes and structures for people's use. For a long time, in order to improve processing efficiency and product quality, steel bars are clamped and fixed during processing. During the processing, the steel bar processed parts need to be stabilized. However, the existing fixing devices have poor stability and are prone to shaking, which affects the quality of the product. For example, in the steel bar metal processing fixing device with authorization announcement number CN216576733U, two first arc-shaped plates for fixing and releasing the steel bar body are installed at one end of the second L-shaped plate, which facilitates the fixation of the steel bar body during processing, reduces the shaking of the steel bar body during processing, and improves the quality of the steel bar body after processing. However, it is impossible to fix steel bar bodies of different sizes, and the fixing structure is difficult to adjust, resulting in reduced practical performance. Utility Model Content
