is in contact with the power transmission recess 6a, thereby preventing the side surface 3c of the mounting portion 3b of the insertion shaft 3 from protruding onto the outer circumferential surface of the rotating shaft 2. When the rotating shaft 2 is rotated in the direction of arrow C by the drive source in this state, the cutter 9 is held in a state protruding outward from the outer peripheral surface of the rotating shaft 2, as shown in FIG. 5 (1). be done. In this manner, the rotating shaft 2 is rotated together with the insertion shaft 3 in a state in which the contact surface 6a of the power transmission recess 6 is in contact with the contact surface 10a of the power transmission projection 10. Therefore, the rotary shaft 2 rotates with the cutter 9 protruding outward from the outer circumferential surface of the rotary shaft 2, thereby realizing cutting by the cutter 9.
次に回転軸2が矢符り方向に回転されたときの刃物9と
回転軸2の回転方向との関係を説明する。Next, the relationship between the cutter 9 and the rotation direction of the rotation shaft 2 when the rotation shaft 2 is rotated in the direction of the arrow mark will be explained.

うなことが防がれる。First, the rotating shaft 2 starts rotating along the direction of the arrow mark. At this time, the insertion shaft 3 is moved into the power transmission recess 6 by the inertia force acting on the power transmission projection 1o against the elastic force of the spring 16.
The rotating shaft 2 remains stationary until the contact surface 6b of the power transmitting projection 10 contacts the contact surface 10b of the power transmission protrusion 10, and therefore only the rotating shaft 2 rotates. At this time, the cutter 9 is located inward from the outer peripheral surface of the rotating shaft 2, as shown in FIG. 5(2). When the rotating shaft 2 further rotates, the rotating shaft 2 and the insertion shaft 3 rotate integrally with the contact surface 6b of the power transmission recess 6 in contact with the contact surface 10b of the power transmission protrusion 1o. Drive. At this time, the cutter 9 is held inward from the outer peripheral surface of the rotating shaft 2, thereby preventing the cutter 9 from coming into contact with the workpiece.
以上のように回転性2の回転方向によって刃物9の回転
軸2の外周面に対する位置が決定される。As described above, the position of the cutter 9 with respect to the outer circumferential surface of the rotating shaft 2 is determined by the rotation direction of the rotatability 2.

However, the ring body 13 may be threaded through the locking member 11 by the set screw 17 while the cutter 9 is located inward from the outer peripheral surface of the rotating shaft 2.

置。[Scope of claims] In a cutting device that performs cutting by rotating a blade using the output of a drive source, a rotating shaft that is rotated by the drive source and has an axis on a straight line passing through the axis of the output shaft of the drive source. A through hole formed in the rotating shaft and having an axis parallel to and offset from the axis of the output shaft, and a power transmission recess provided at one end in the longitudinal direction. an insertion shaft that is inserted into the insertion hole and is rotatable relative to the rotation shaft and has a power transmission protrusion near one end; the rotation shaft and the insertion shaft; an elastic connecting means for resiliently connecting the two ends of the insertion shaft, and a blade protruding laterally and attached to the vicinity of the one end of the insertion shaft, wherein one side of the power transmission protrusion is connected to one side of the power transmission recess. When the cutter is in contact with the side surface, the cutter is located inward from the outer circumferential surface of the rotating shaft, and when the other side surface of the power transmission protrusion is in contact with the other side surface of the power transmission recess, the cutter is located inside the outer peripheral surface of the rotary shaft. A cutting device characterized by being located outward from the outer peripheral surface.
