The character-shaped roll-over prevention leg 10 attaches the bottom plate 12 to the fixed plate 1 and
It is attached in a state that it projects to both outer sides of the moving board 4.
Since the roll-over prevention leg 10 is located directly below the cut surface,
It is difficult to do so that steel bars can be cut accurately. Only
Also in the present invention, it is positioned outside the side plate 11 of the roll-over prevention leg 10.
Since the fixed shaft 5 is fixed by the nut 17 that is set,
Even if the movable platen 4 rotates, the nut 17 does not loosen.
In the embodiment, the roll-over preventing leg 10 is formed by bending a metal plate material, but it goes without saying that the side plate and the bottom plate may be welded or cast.

The proposed steel bar cutter has a bottom plate fixed just below the cutting surface of the movable plate.
Remove the roll-over prevention legs that protrude to the outside of both the surface plate and movable plate.
Since it is attached, it has good stability and can cut steel bars stably.
You can Also, since the side plate of the roll-over prevention leg supports the movable plate by pivotally supporting the fixed shaft, the force that distorts the fixed shaft during cutting is not absorbed and the movable plate is not twisted. Since the movable plate is clamped and fixed via the side plate, the nut does not loosen even when the movable plate rotates during cutting, and the cutting surface does not become rough due to the loosening of the nut, and cutting defects do not occur. there is an advantage that can be accurately cut the steel bars such.
