Abstract:
1. A bar steel cutting tool in which a fixed blade body and a rotary blade body that is capable of rotating around a first shaft, by operating a handle in a condition in which the fixed blade body and the rotary blade body are fitted to each other, are provided at a front end of a tool base for shearing bar steel by means of concave blades formed on outer peripheries of the fixed blade body and the rotary blade body, wherein the handle is constructed in such a way that a front end of a proximal portion of the handle is supported by a second shaft that it is located at a position above the tool base, and that is equipped with an elongated hole that extends obliquely in a backward direction from the second shaft, and the rotary blade body forms branch portions which squeeze both the right and left sides of the proximal portion of the handle at a rear end of an arm portion that extends in a backward direction, and the branch portions are bent upwards so as to bypass the second shaft, and so as to support both sides of a pin which slides within the elongated hole.
