ている。2. Description of the Related Art A hair cutter is provided with a comb-teeth-shaped fixed blade and a comb-teeth-shaped movable blade which is also slidable with respect to the fixed blade. Conventionally, it was attached as shown in FIG. In the figure, 20 is a blade base, and the fixed blade 21 is directly fixed to the blade base 20. The movable blade 22, which is slidable in the left-right direction in the drawing with respect to the fixed blade 21, includes a coupling engagement portion 24 with the reciprocating drive mechanism,
A guide plate 23 including 25 is fixed to one surface, and is attached to the blade base 20 by a pressing spring 26 that also has a function of pressing the movable blade 22 against the fixed blade 21.

刃２２に係合している。The pressing spring 26 here is of a torsion coil spring type having a pair of coil portions 26a and 26b having different winding directions. The central portion engages with the blade base 20, and the coil portions 26a and 26b have blades. Both free ends of the pressing spring 26 held by the base 20 are engaged with the movable blade 22.

荷が大きいという問題を有している。At this time, when the end portions of the coil portions 26a and 26b of the pressing spring 26 are fixedly supported by the blade base 20 so as not to move, the movable blade 22 moves from the reciprocating drive mechanism. When moving left and right due to the input of
While stress is applied to the outer ends of 6a and 26b,
There are problems that noise is generated due to collision with the blade base 20 and that the load is large.

Although the notch 200 is provided in a portion of the blade base 20 which is located on the outer end of the coil portions 26a and 26b, the movable blade 2 can be removed as shown in FIG.
As the outer end portions of the coil portions 26a and 26b swing in a direction orthogonal to the reciprocating direction of the movable blade 22 with the left and right movement of 2, the left and right reciprocating movement of the movable blade 22 is linear. Instead, it becomes a movement of drawing a figure 8, and the cutting efficiency is low.

This hair cutter is, as shown in FIG. 2, in the shape of a square tube and has a cutting height adjusting handle 10 on one surface and one side surface. The power switch 11 has a blade block 2 mounted on the front end side of a main body housing 1 having a slide handle 12 for an attachment panel disposed on the other side. A wide blade base 20, a fixed blade 21 fixed to one surface of the blade base 20, and a movable blade 2 slidable with respect to the fixed blade 21.
2, and a pair of pressing springs 26, 26. The fixed blade 21 and the movable blade 22 are also formed wider than the main body housing 1. As shown in FIG. 3, the groove-shaped coupling engagement portion 27 provided on the guide plate 23 fixed to the movable blade 22 is provided with the eccentric pin 32 provided on the output shaft of the motor 3 via the joint 31. The movable blade 22 reciprocates as the motor 3 rotates.

っている。As described above, the movable blade 22 here is provided with a pair of pressing springs 26, 26 so that the blade base 20 can be moved.
And is pressed against the fixed blade 21. Each pressing spring 26 has a pair of coil portions 26a, 2 having different winding directions, as in the conventional example.
6b is a torsion coil spring type, the center part of which is engaged with the blade base 20 and the coil parts 26a, 26b are held by the blade base 20, and both free ends of which are engaged with the movable blade 22. I am fit. In addition, the supporting and fixing portion of the coil portions 26 a and 26 b in the blade base 20 is the coil portion 26.
The outer end portions of a and 26b are allowed to move as shown in FIG.

When the movable blade 22 moves to the left in the figure because the outer ends of the a and 26b swing in the direction orthogonal to the reciprocating direction of the movable blade 22, as shown in FIG.
Is to pull the movable blade 22 with its free end on the left side (A, C in the figure) and push the movable blade 22 with its free end on the right side (B, D in the figure). Since the movements of A and D and the movements of B and C on the left and right of the coupling engagement portion 27 cancel each other, the movable blade 22 makes a linear reciprocating movement without causing an 8-shaped movement.

往復運動は直線的で切断効率が良いものとなる。As described above, according to the present invention, a pair of pressing springs are provided, and the free ends of the pressing springs are engaged with both sides of the connecting engagement portion of the movable blade with the reciprocating drive mechanism. Therefore, the movement of the pressing spring that attempts to make the movable blade draw an 8-shaped movement cancels each other out in both pressing springs, and therefore the reciprocating movement of the movable blade is linear and the cutting efficiency is good.
