を考慮して設定すればよい。As shown in FIGS. 2 and 3, the inner cutter holder 9 consists of two connecting tubes 10 and a spacer 11, and each cutter blade 7 has two holes 12, which are connected to each other. tube 10
A large number of them are inserted through the spacers 11 so as to be arranged in parallel. The connecting pipe 10 is made of a metal such as aluminum, brass, or stainless steel, which is softer than the small blade 7.
Push a mechanical or hydraulic pipe expanding means, such as a burnishing rod B (see FIG. 3) as a mechanical means, into the hollow interior of 0.
The connecting pipe 10 is expanded in the diameter direction and the connecting pipe 10 is attached to the small blade 7.
By biting into the small blade 7, the small blade 7 is fixed to the connecting pipe 10. In this way, by passing the small blade 7 through the connecting pipe 10, the inner cutter 4 whose cutting edge is easily aligned along the concave curved inner surface of the outer cutter 2 can be obtained. Note that one or three or more connecting pipes 10 may be used, and the connecting pipes 10 may be set in consideration of fixing strength, pipe diameter, and small blade diameter.

During this sharpening, the cutter blades 7 with the same diameter are A grinding wheel is passed through the polishing rod 13 and set in a cylindrical shape, and this is subjected to centerless polishing as shown in FIG. By doing this, you can easily attach the blade.

とも簡単に作ることができる。FIG. 6 shows another embodiment in which each small blade 7
Almost the lower half of the blade is insert molded into the inner blade holder 9 made of plastic. In this case, in order to hold the cutter blades 7 inside the mold, the inner cutter holder 9 made of plastic can be used to embed and fix the cutter blades 7 at predetermined intervals without necessarily using the connecting tube 10 and the spacer 11. In the above embodiment, the spacer 11 or the part that determines the pitch between the cutter blades 7 is
Regardless of the diameter of the small blade, the length of the inner cutter 4 is the same over the entire length from one end to the other, so the amount of protrusion of the cutter blade 7 differs between the ends and the center of the inner cutter 4, and there is a portion where the amount of protrusion is small. In this case, it is difficult to cut the long hair, and the blow-out of hair becomes noticeable, and conversely, in the part where there is a lot of hair, the small blade 7 becomes easy to bend, and the cutting quality deteriorates.
Moreover, the cutting edge becomes easily damaged. For this purpose, the diameter of the spacer 11 etc. may be made to correspond to the diameter of the small blade so that the amount of protrusion is approximately constant. In addition, if you want to make the spacer diameter satisfactory for cutting long hair and hair debris at both ends of the inner blade 4 and keep it constant over the entire length, you can make the plate thickness of the small blade 7 thicker toward the center, or It is also possible to use a cutter blade material that has high strength despite its thickness, or to take measures in shape such as reinforcing ribs to increase the strength of the cutter blade itself. In addition, the cutter blades 7 do not have to change the diameter of each cutter blade 7 sequentially, but instead make a plurality of adjacent cutter blades the same diameter, change the diameter for each block, and grind the blades so that they follow the curved inner wall of the outer cutter 2. If you do this, you can easily make it without increasing the polishing cost too much.
