な切断作業とすることができる。The above-described effect will be described in detail. When cutting is performed while sandwiching the columnar object S by the fixed jaw-side cut body Cf provided on the fixed jaw main body 2 and the movable jaw-side cut body Cm provided on the movable jaw main body 3. In addition, the object S to be cut is subjected to a rotational moment about the cut portion by the shearing force received from the fixed jaw-side cut body Cf and the movable jaw-side cut body Cm, and the fixed jaw main body 2 and the movable jaw are moved. The object S is inclined with respect to the opening / closing direction of the main body 3, so that the object S collides with the surfaces of the fixed jaw main body 2 and the movable jaw main body 3 on both sides from the cut position, and the cutting does not proceed further. In the present invention, the movable jaw-side cut body C with respect to the fixed jaw-side cut body Cf
The fixed jaw-side small recess 2b is provided on the fixed jaw-side crushing surface 2a of the m-side fixed jaw body 2, and the movable jaw-side crushing surface of the movable jaw body 3 on the fixed jaw-side cut body Cf side with respect to the movable jaw-side cut body Cm. Since the movable jaw-side small recess 3b is formed in each of the movable jaw-side small recesses 3b, one side of the cut portion of the workpiece S escapes to the fixed jaw-side small recess 2b, and the other side escapes to the movable jaw-side small recess 3b. The object S is a fixed jaw body 2 and a movable jaw body 3
A good cutting operation can be performed without hitting the surface of the cutting device and disturbing the cutting operation.

The fixed jaw side small depression 2b is provided on the fixed jaw side crushing surface 2a of the fixed jaw main body 2 on the movable jaw side cut body Cm side with respect to the fixed jaw side cut body Cf. ,
The movable jaw side crushing surface 3a of the movable jaw body 3 on the fixed jaw side cut body Cf side with respect to the movable jaw side cut body Cm is formed.

It is only necessary that the cut end of s be large enough to be accommodated.
Since it does not form a large excision portion as a storage space for s, sufficient mechanical strength can be ensured.

大きくなっている。Further, the fixed jaw-side small recess 2b and the movable jaw-side small recess 3b may be recesses of a required size with respect to the fixed jaw main body 2 and the movable jaw main body 3. The fixed jaw side of the jaw body 2 for cutting out all the relevant portions near the cut surface side of the fixed jaw side cut body Cf of the jaw body 2 and the movable jaw side cut body Cm of the movable jaw body 3 near the respective cut plane side. The dimensions in the width direction of the crushing surface 2a and the movable jaw-side crushing surface 3a do not become extremely small, and specifically,
As shown in FIG. 7, a fixed jaw body 2, the height H 2 next to be construed provided fixed jaw side small recess 2b, equivalent section modulus and so as to the height H 20 (conventional type size) Which is much larger than that of the present invention.
Similarly, in the movable jaw main body 3, as shown in FIG.
Although those provided movable jaw side small recess 3b is a height H 3, equal when such a section modulus height H 30 (conventional type size), and extremely large in comparison with those of the present invention Has become.

There is also an advantage that the size in the direction (perpendicular to the width direction) can be reduced to be compact.
