An inner shaft 2 is screwed to an outer shaft 1, and a tip 3 is screwed to a front portion of the inner shaft 2. In addition, an O-ring 4 for preventing screw loosening is interposed between the inner shaft 2 and the tip 3. A pair of bearings 5 are built in the front part of the inner shaft 2, and a fixing tool including a front fixing tool 6 and a rear fixing tool 7 is sandwiched between inner rings 5 </ b> A of the bearing 5. To describe the fixing device in more detail,
At the rear outside 6A of the front fixture 6, the front inside 7A of the rear fixture 7
Is press-fitted, and the rear end of the front fixture 6 and the inner step 7 of the rear fixture 7 are
An O-ring 8 is attached between the O-ring 8 and B. Further, the blade bar 9 is inserted into the inner ring 5 </ b> A of the pair of bearings 5 so that it can be freely inserted and removed, and the blade bar 9 is press-fitted and locked by the O-ring 8 so that it can be pulled out. The blade bar 9 has a round bar shape, and the distal end of the blade portion 9A formed at the distal end is formed at a position slightly shifted from the axis. Also, since the rear end portion 9B of the blade bar 9 is formed in a conical shape, when the blade bar 9 is received by a push bar 10 described later, the blade bar 9
Is not impaired. A push rod 10 is screwed into the inner shaft 2 so that its longitudinal position can be adjusted, and an O-ring 11 provided in a concave groove 10A of the push rod 10 is pressed against the inner surface 2A of the inner shaft 2 so that the screw of the push rod 10 is screwed. Loosening is prevented. The conical rear end 9 of the blade bar 9 is provided at the front end of the push rod 10.
B is abutted, and by adjusting the longitudinal position of the push rod 10, the protrusion length of the blade portion 9A of the blade bar 9 is adjusted.
【0006】このカッティングペンは、自動カッティン

A concave groove 12A partially penetrating inside is formed, and O is formed in the concave groove 12A.
The ring 8 is fitted. Therefore, the concave groove 12A
A part of the O-ring 8 protrudes inward from the part penetrated by
It comes into pressure contact with the blade bar 9.
