[0002] Steel bar cutting refers to the process of cutting steel bars according to the design requirements in construction.

[0003] After searching, Chinese patent number CN117862374A discloses a steel bar cutting machine for construction projects. The cutting length is determined by a control component. At the same time, the control component can also synchronously drive the moving component to move. After the moving component drives the cutting component to move to the specified position, the cutting component can cut the steel bars on the control component. It can simultaneously cut several steel bars, effectively improving the efficiency of steel bar cutting. However, in the above patented product, the steel bars are fixed by the docking arc blocks to complete the limit. However, when used in construction, steel bars of different specifications and sizes are required. The diameters of the steel bars are different. If they cannot fit tightly with the outer wall of the steel bar during cutting, the steel bars will be displaced during the cutting process, resulting in an uneven cutting surface and unqualified cutting dimensions.
