And the blade 2 reciprocates in the longitudinal direction (vertical direction) of the blade 2, and the object 4 is cut by the blade 2. When the blade 2 is driven in this manner, the blade edge of the blade 2 moves as shown by an arrow in FIG. 7, swings back and forth, and reciprocates up and down. Here, X is the amount to move up and down, and Y is the amount to reciprocate back and forth. When cutting with a cutting tool, the base 5 is moved along the surface of the workpiece 4 and moved forward to be cut forward by the cutting blade portion 3a on the front side of the blade 2 and to move rearward after the blade 2 Side cutting edge 3
b. When cutting into the object 4 without drilling a pilot hole, one end of the base 5 is brought into contact with the object 4 as shown in FIG. 8, and the contacted portion is used as a fulcrum in the direction of the arrow in FIG. , And the cutting tool 3 is cut mainly at the cutting edge 3c at the lower end of the cutting tool 2 so that the cutting tool 2 penetrates the object 4 to be cut. In adjusting the protrusion of the blade 2, the tightening screw 18 is loosened, the blade 2 is moved up and down using the semi-cylindrical projection 23a as the boss 23 as a guide, the protrusion is adjusted, and the tightening screw 18 is tightened. Further, since the blade 2 swings back and forth and reciprocates up and down and cuts, the cutting width to be cut is larger than the blade width of the blade 2. Therefore, a mark 21 indicating the range of the cut width is provided on the base 5. As the mark 21, in this embodiment, the cutout portion 21a of the same width as the cut width to the side edge of the base 5
Is provided.
