9b, and the engagement pin 20 fits into the engagement recess 53' of the blade frame for advancing and retreating. In this case, the cutting edge of the blade block 7 is movable back and forth between the comb tip side and the base end side of the comb teeth of the fixed comb 40, so that hair can be styled with a comb.

The movable comb 6 has a bearing hole 55 bored in the longitudinal direction at its base end, and is provided with a fan-shaped tooth body 56 constituting an opening/closing means 70 on the side facing the recess 38 at the base end.
A protrusion 58 corresponding to the thickness of the comb teeth of the fixed comb 40 is formed at the tip of the comb teeth 57 on the side facing the recess 38 . This movable comb 6 is fitted into the recess 38' of the housing 5, the support shaft 59 is passed through the bearing hole 55, and a torsion coil spring 60 is used to facilitate return.
The movable comb 6 is rotatably mounted in the recess 38' by fixing both ends of the support shaft 59 to the end walls of the recess 38' via the . In this open/closed state, the protruding portion 58 of the comb teeth 57 is positioned flush with the tips of the comb teeth of the fixed comb 40, and the fan-shaped tooth body 56 enters the insertion hole 40'. The opening/closing means 70 includes an operating section 62 having a gear 61 that meshes with the teeth of the fan-shaped tooth body 56 as shown in FIG. 15, and a recess 3 as shown in FIG.
8' into the notch 65 formed in the end wall of the gear 6.
1 center pin 63 is supported by its notch 65, and the gear 61 is meshed with the fan-shaped tooth body 56. In addition, since the operation part 62 of the movable comb 6 is disposed at the tip of the housings 4 and 5, it can be stably operated with the other hand that is not gripping the housings 4 and 5.

The operation of this hair clip will be explained. That is, FIG. 13 shows that the protrusion 35b of the lock button 35 is clicked over the boss 36 to lock the lock hole 2.
3, the handle 21 is released from the return spring 2.
2, the bent end 21a of the handle 21
is not pressing the switch spring 25, so the switch is off, and the engagement pin 20 of the lever 18 is pushed into the hole 3 by the handle 21 as shown in FIG.
9, and the cutting edge of the blade block 7 is at the 9th position.
As shown in the figure, the fixed comb 40 is moved backward from the base end. Furthermore, in the closed state, the movable comb 6 overlaps the fixed comb 40 to form a single comb as shown in FIGS. can. FIG. 14 shows that the middle part of the handle 21 is pressed to compress the return spring 22, and the bent piece 2 of the handle 21 is compressed.
At the same time, the lever 18 rotates around the boss 17 and the engagement pin 20 is positioned in front of the hole 39 as shown in FIG. The blade block 7 is connected to a comb 6 whose cutting edge is movable as shown in Fig. 10.
Move forward so that it is positioned in front of the comb teeth (sometimes it protrudes from the comb teeth, and sometimes it is also positioned in the middle of the comb teeth). On the other hand, by driving the motor 8, the pinion 1
5 rotates the gear 14, and the gear 14 cranks the drive rod 16 through the eccentric cam 13, and its engagement pin 17 reciprocates through the guide hole 41 to operate the driver 49, that is, the movable blade 50. In this state, if the handle 21 is fixed by pushing the tip 35a of the lock button 35 into the lock hole 24, the same state will be maintained even if the handle 21 is released. Further, in this state, when the movable comb 6 is in the closed state, normal hair styling can be performed.

Next, to open the movable comb 6, proceed as follows. That is, as shown in FIG. 19, the thumb N of the hand that does not have the grip 2 is supported on the push piece 42, and the index finger M is placed on the lever 62 and the pinch operation is performed (the 21st
) to rotate the lever 62. The rotation of the lever 62 causes the bevel gear 61 to rotate, and the fan-shaped gear 56 meshed with the bevel gear 61 to follow. As a result, the movable comb 6 rotates around the support shaft 63 and opens by an angle θ (FIG. 20). Therefore, as shown in FIG. 22, when the back side (contact surface side) of the movable comb 6 is placed on the back of the head P and the handle 21 is turned on (pushed in), the movable comb 6 will be held at almost the fixed position without sliding. and the angle θ
This will allow you to cut the grass evenly. Further, in this state, if the entire head Y is moved as shown in FIG. 23, the hair can be styled with a constant cutting height.

As described above, the hair clipper with a cutting comb of the present invention has a blade block arranged on a fixed comb,
Since the movable comb is arranged so that it can be opened and closed against the contact surface of the fixed comb, the movable comb and the fixed comb can lift up the hair while cutting it, making it extremely easy and clean for even an amateur to cut the hair with one hand, while also achieving the desired cutting height. It also has the effect of being able to cut the entire piece evenly.
