34 are erected integrally.

Therefore, even when the knob portion 232 is pinched by the finger 34 and strongly pressed downward, the fingertip is blocked by the convex portion 234, and the cutting edge 28b.
It does not slip in any direction, and is even safer than that of the above embodiment.

The convex portion 234 is, as shown in FIG. 12, a knob portion 2
It may be formed in the left-right direction of 32, and in this case, both fingertips are blocked by the convex portion 234, which is even safer.

[Advantages of the Invention] According to the present invention, a blade extending outward from the center of rotation is provided on the upper surface of a disk-shaped cutter, and a plate-shaped knob portion protruding upward is provided at the center of rotation of the disk-shaped cutter upper surface. Since the lower end of the knob is integrally provided with a step higher than the blade, and the longitudinal end of the knob is arranged to face the central end of the blade, the cutter can be attached to and detached from the rotary shaft. It is easy, and even if you pinch the knob, the fingertip will come into contact with the stepped portion at a position higher than the blade edge of the cutter, so the fingertip will not contact the blade edge in the center direction of the blade of the cutter. . Therefore, the finger is not injured when the cutter is attached to or detached from the rotary shaft.

In addition, the knob part is formed in a plate shape that can be held by fingers, and the blade edge in the center direction of the cutter blade is located near the end face in the thickness direction of the knob portion that faces the blade edge. The part is easy to pinch with a finger, and even if the fingertip slips on the step, the fingertip will straddle the blade edge of the cutter and will contact the cutter surfaces on both sides, so it will not contact the blade edge. Not safe.

Moreover, since the knob portion is formed in a plate shape, sink marks do not occur when molded with synthetic resin.
