る。A cutting action portion 6 having a cutting blade is provided so as to project from the main body portion 4 in a direction opposite to the protruding direction of the handle portion 5 that is integrally provided so as to project from the main body portion 4. Here, the cutting action portion 6 provided with a cutting blade is provided so as to project in a direction orthogonal to the axis of the main body portion 4, and as shown in FIG. The handle portion 5 is arranged such that the axis line of the handle portion 5 intersects or is substantially orthogonal to the axis line of the object to be sheared a when the axis lines of the portion 4 are arranged in parallel. The cutting action portion 6 is composed of a fixed arm 10 having a fixed blade 9 at the tip and a movable arm 12 having a movable blade 11 at the tip, and the movable arm 10 with respect to the fixed blade 9 of the fixed arm 10. The movable arm 12 is rotatably moved so that the movable blade 11 moves closer to or away from the movable arm 11. The fixed blade 9 and the movable blade 11 are fixed by a mounting bolt 17 to the fixed arm 1 respectively.
0 or fixed to the tip of the movable arm 12. The motor 1 is housed at one end of the body 4 of the body,
Next to the motor 1, a speed reduction block 13 as a speed reduction device 2 for increasing the rotational torque of the motor 1 is composed of planetary gears, and finally a cutting blade drive in which a cam 14 is formed on one side is provided. It is adapted to be transmitted to the cam shaft 15 as the mechanism 3. The rotatively driven cam 14 is a roller 1 provided at the end of the movable arm 12 as shown in FIG.
6, the cam 14 is driven to rotate by the roller 16
Is transmitted to the movable arm 12 via. According to the shape of the cam 14, the movable arm 12 to which the movable blade 11 is fixed at the upper end follows, so that the object to be sheared a such as all screw bolts can be sheared by the fixed blade 9 and the movable blade 11. ing. Here, the cutting action portion 6 and the cam 14 for operating the cutting action portion 6 are arranged separately on both sides with respect to the axis of the cutting blade drive mechanism 3, and are driven and moved when performing the shearing operation. The cutting action portion 6 and the cam 14 are arranged on both sides with respect to the axis of the cutting blade drive mechanism 3 so that a comfortable work can be performed with good weight balance during shearing work.

く、楽に次工程に移ることが可能となるものである。When cutting a to-be-sheared object a such as a projecting all-screw bolt installed on a fixed structure, the projecting all-screw bolt requires no post-processing (burring). As shown in FIG. 6, only the blade body having the acute angled blade 19 is attached to the necessary side total screw bolt X side shown in b), and the cut portion of the total screw bolt X after shearing is not burred. As described above, since all the unnecessary screw bolts Y on the unnecessary side are unnecessary, only the blade body having the obtuse angle blade 20 can be attached as shown in FIG. That is, the fixed blade 9, the fixed arm 10, and the movable blade 1
1. The position of the bolt insertion hole 22 or the like provided in the blade mounting recess 23 where the movable arm 12 is arranged (the dimensional relationships in FIGS. 6 and 7 are A = A ′, B ≠ B ′, C ≠
C ') are different from each other, and the fixed blade 9 having an acute-angled blade 19 at its end is fixed to the fixed arm 10, and the movable blade 11 having an obtuse-angled blade 20 at its end is uniquely attached to the movable arm 12. It is incompatible because it is limited. By making the two blades incompatible with each other in this way, as shown in FIGS. 3 and 4, all screw bolts X on the necessary side which are required in the post-construction work.
The cutting blade to be positioned on the side has an acute-angled blade 19 at the end, and the cutting blade to be positioned on the unnecessary screw Y side on the unnecessary side that is unnecessary in the post-work is an obtuse angle blade 20 at the end. Therefore, it is possible to limit the direction in which burrs come out. That is, one of the blades has a blade 19 having an acute angle on the cutting surface, and the other blade has a blade 20 having an obtuse angle on the cutting surface, and the blade has an acute blade 19 on the structure side. By allowing one of the blades to be attached, it is possible to prevent burrs from occurring at the ends of the all-screw bolts X on the side to be left, so that it is not necessary to perform finishing work after cutting the object to be sheared a, and it is easy to perform. It is possible to move to the next step.
