おけばよい。 The embodiment of the present invention is configured as described above, and the configuration is simplified by making the cutting blade mounting surface 10 of the cutting blade holder 3 a flat surface, which facilitates manufacturing, improves productivity, and improves productivity. Cost reduction can be achieved. To adjust the protrusion of the cutting edge portion 22 of the cutting blade 11, use a jig (not shown) to stack the cutting blade support seat 12, the cutting blade 11, and the cutting blade retainer 13, and place the positioning bolt 17 on top of each other.
After positioning with the pin portion 18 of the cutting blade 11 and adjusting by interposing an appropriate number of adjustment plates 21 between the back of the cutting blade 11 and the base 19 of the cutting blade support seat 12, the positioning bolt 17
is screwed forward, and the cutting blade 11 is clamped and fixed between the cutting blade support seat 12 and the cutting blade presser 13. In this state, if the pin part 18 is inserted into the positioning hole 20 of the cutting blade attachment surface 10, positioned, and fastened with the bolt 16, a predetermined protrusion can be obtained. In this way, if the cutting blade is attached to the cutting blade mounting surface 10 with the protrusion adjusted in advance, a predetermined protrusion can be obtained, and the adjustment work for the protrusion can be easily performed. Furthermore, by preparing a large number of cutting blade support seats 12 with different heights of the seats 23, it is possible to easily obtain a variety of uneven arrangements of the cutting edge portion 22 that are optimal according to the diameter of the cut wood. It also has a simple configuration and can be easily manufactured. In addition, since the cutting blade mounting surface 10 is a flat surface, it is possible to use a single wide cutting blade that spans almost the entire length of the cutting edge 6 in the longitudinal direction, and can also be used as the cutting blade holder 3 for cutting small diameter materials. It is very versatile. In addition, in response to the unevenness of the cutting edge portion 22 side of the cutting blade 11, the cutting edge 1 of the cutting edge blade 8
The first edge may be provided with an uneven shape or the like.
