Technique (3) is inserted in between, and the branch (3) is created by sliding the movable blade (tsu).
) was cut, but between the comb blade ('2a') of the movable blade (2) and the comb blade (la') of the fixed blade (11), there was a gap between the entire comb blade (la').
θ was formed, and the side walls (cutting edges) of both comb blades (la') (2a') were straight. For this reason, if a branch (3) is sandwiched between the fixed blade (11) and the movable blade (2), the branch (

るという欠点があった。The resultant force acts, and the cane (3) easily slides outward and escapes, causing the branch (
3) was half-cut without being cut reliably, resulting in poor cutting quality (l).Also, in order to prevent technique (3) from slipping, a fixed blade (1) was used as shown in Figure 2. (
The comb blade (la')fl! There was one in which four arc-shaped parts (4) were formed on the wall, but as shown in Fig. 5(a) and (b), the uncut portion of the cane (3) when cutting the branch (Fig. 5(a)) a)
(shaded area) occurs, so a component force Gy of G is applied to the movable blade (2).
There is a problem in that the comb blade (2a') of the movable blade (2; falls toward the fixed blade (f) side due to the action of The contact point A' becomes the fulcrum, and the convex part (5) of the fixed blade (1) collides with the cutting edge m'< 6) of the side wall of the movable blade (2), and the fixed blade (
There was a drawback that the cutting edge (6) of the movable blade (2) was damaged by the protrusion (5) of 1j, and the edge of the protrusion (5) of the fixed blade (1) was also worn out.

機の刃部を提供するにある。The present invention has been made in view of the drawbacks of the conventional examples, and its purpose is to form substantially parallel portions on the comb blade side wall of the fixed blade and the comb blade side wall of the movable blade. To provide a blade part of a trimmer that can surely cut a branch without causing blade edge interference between the fixed blade and the movable blade and without causing the branch to escape from between the fixed blade and the movable blade.

Comb blade (2a) 01 with movable blade (2) on the wall! The blade of the trimmer is characterized by having a part that is approximately parallel to the I wall, which eliminates branch slippage and allows for reliable cutting without missing branches. This prevents damage to the cutting blade due to collision between the blades.

破損や固定刃（１）の摩耗を防止できるのである。As shown in Fig. 5, the fixed blade (1) has a protrusion 4 at the center on both sides, and the side wall of the comb blade (1a) is connected to the comb blade (2a) of the movable blade (2) on the base side of the protrusion 0I. parallel to the side wall (a
a/b b). As a result, when the branch (3) is introduced between the comb blades (laX2a), the cane (3) receives a force J from the movable blade (2) and a force J' from the fixed blade (1).
7 > 1 offset - Branch (3) I will not slide along the side wall and escape, and when the branch (3) is finished cutting, there will be uncut parts as shown in Figure 6 (a) and (b). Because there is no
The movable blade (2) no longer falls toward the fixed blade (1), which prevents damage to the cutting edge O (g) of the movable blade (2) and wear of the fixed blade (1) due to interference between the blade edges. .

A rounded convex portion (B) and a concave portion 0 are continuously formed on the side wall of 1a), and corresponding to this convex portion (6), a comb blade (2a) side wall of the movable blade (2) is formed with a radiused convex portion (B) and a concave portion 0. A concave notch Q41 with the same radius as the convex part (6) is formed, and the convex @ and concave part 0 of the fixed blade (1) and the concave notch α→ of the movable blade (2) are smooth with other parts. are formed continuously. Therefore, when the branch (3) is introduced between the comb blades (1a) of the fixed blade (1),
The branch (3) is reliably captured by the concave and convex portion (6) of the fixed blade (1) and the concave notch Q4 of the movable blade (2), and the branch (3) is captured without slipping along the side wall. is reliably cut by the operation of the movable blade (2). At this time, ′j
As shown in Figure J11 (a), the movable blade (2) and the fixed blade (
In 1), each side wall coincides between point A and point 0, so there is no uncut part in technique (3), and the movable blade (2) does not fall toward the fixed blade (1), preventing blade edge interference. It is possible to prevent damage to the cutting edge due to Furthermore, since the uneven part a3@ of the fixed blade (1) and the concave part α1 of the movable blade (2) are smoothly continuous with other parts, it is possible to prevent the branch (3) from cracking. [Effects of the Invention] Since the present invention is constructed as described above, it is possible to reliably cut the branches caught between the fixed blade and the movable blade without missing them, and there is no half-cut, resulting in good cutting ability and easy cutting. It has the advantage of being efficient. Moreover, by cutting the branches at mutually parallel portions, the branches can be cut without interference between the cutting edges, and there is an advantage that the life of the cutting edge can be extended.
