Since the clamping block 707 is located inside the limiting groove 703, the clamping block 707 can be moved to fit the surface of the steel bar 8. At this time, the arc-shaped groove 708 opened on the surface of the clamping block 707 can just fit the steel bar 8. At this time, the two clamping blocks 707 can squeeze and fix the two sides of the surface of the steel bar 8.
[0033] In one embodiment, the four T-shaped sliders 604 are evenly divided into two groups, and both groups of T-shaped sliders 604 are movable inside the two T-shaped movable grooves 102.

At this time, the steel bar 8 can be located inside the two arc-shaped grooves 708 and clamped and fixed by the two clamping blocks 707.
[0037] Working principle: when the steel bars used in steel structure buildings are cut, the steel bars 8 are placed in the arc-shaped placement grooves 704 opened on the surfaces of the two U-shaped support plates 701. Since the two U-shaped support plates 701 can be moved, the staff can move the two U-shaped support plates 701 according to the position where the steel bars 8 need to be cut, so that the two ends of the cut steel bars 8 can be stably placed. After placement, the two knob bolts 706 can be screwed inward. While screwing, the two knob bolts 706 can drive the clamping block 707 at one end to fit on the surface of the steel bars 8, so that the steel bars 8 are located inside the two arc grooves 708 and are clamped and fixed. At this time, the two U-shaped support plates 701 fix two positions on the surface of the steel bars 8 respectively. At this time, the four electric push rods 601 are started by the external controller. The operation of the electric push rods 601 can drive the clamping block 602 at one end to gradually move toward the steel bars 8, so that the four arc grooves 603 can fit on the surface of the steel bars 8. At this time, the four clamping blocks 602 can clamp the steel bars 8 is clamped and fixed for the second time. By setting the clamping component 6 and the fixing component 7, the placement of the steel bar 8 when being cut can be made stable, and the displacement of the steel bar 8 during the cutting process can be avoided to cause the cutting deviation, which can improve the effect of steel bar cutting; the forward and reverse motor 301 can be started by the external controller, and the operation of the forward and reverse motor 301 can drive the threaded rod 302 to rotate forward and reversely. At this time, the cutting knife 404 is moved according to the position where the steel bar 8 needs to be cut, and the electric telescopic rod 401 and the motor 403 are started by the external controller. The operation of the electric telescopic rod 401 can drive the cutting knife 404 downward. At this time, the motor 403 operates and drives the cutting knife 404 to cut and cut the steel bar 8. Since the two fixing components 7 fix the two ends of the cut steel bar 8, the steel bar 8 will not fall down after being cut to affect the cut section. By setting the moving device 3, the steel bar can be cut at different positions, which can avoid manual adjustment, reduce the workload of the staff, and is more convenient.
