Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a steel bar cutting machine. Background Art

[0002] The steel bar cutting machine is one of the important equipment on the steel bar processing production line, which is used to cut the steel bar into multiple sections to meet the cutting requirements of steel bars with different lengths and provide steel bar materials for engineering construction;

[0003] The common cutting machine drives the cutting cutter head through a motor, and then manually presses it down to make it contact with the steel bar for cutting operation. However, in actual operation, it is found that: before cutting the steel bar, it needs to be fixed. The common fixing method is to drive a pressing plate to move by rotating a threaded rod to clamp and fix the steel bar. However, most of the cutting operations are relatively frequent. Although this method of fixing the steel bar is simple and effective, the method of fixing the steel bar frequently, then cutting, then releasing the fixation to remove the steel bar, and then fixing the next section of the steel bar again is relatively cumbersome, which will waste a lot of time. Moreover, the common cutting machine only has a hand-held part at the end of the pressing cutting piece. When cutting, there is also a need to further increase the contact with the machine to increase its stability and facilitate the hand to exert force to press down. Summary of the Utility Model
