2) when the front end of the steel bar is conveyed to the position of the limiting plate (1103), the limiting plate (1103) is driven to rotate, the striker (1113) is driven to move left, the push plate (1105) is driven to move left in the left moving process of the striker (1113), the push plate (1105) moves left to drive the rotation of the rotation plate (1102), the rotation plate (1102) is moved above the cutter rest (137), meanwhile, the motor (8) drives the cutting mechanism (13) to move through the transmission mechanism, and the cutting mechanism (13) moves downwards to cut the steel bar;

3) after the reinforcing steel bars are cut off, the reinforcing steel bars fall onto the material rack (6) and slide into the material rack (6) under the action of the inclined plane;

4) the limiting plate (1103) and the cutter frame (137) are reset to prepare for the next fixed-length cutting step.
