17A to 19I are diagrams showing a state of cutting hair while rotating the hair clipper according to the third embodiment. Fig. 17A shows the hairs 51, 53 near the head and the hairs 52, 54 near the cheeks in the human hair 50. Figure 17B shows an enlarged view of the hair 54 near the face. As shown in FIG. 18E and FIG. 18F , when cutting hair, the roller brush portion 6A is rotated in the direction of the rotation direction mark 12 .

By alternately arranging the hair cutting scraper 3A and the tooth needle 2A in the roller brush part 6A, the hair cutting scraper 3A1 can be used to rotate the roller brush part 6A from the inner side of the hair (the space between the hair and the body) in an oblique direction. Cut hair.

Next, as shown in FIG. 18D , the hair can be cut obliquely with the hair cutting scraper 3A2 while rotating the roller brush portion 6A.

As shown in Figure 18E, the angle formed by the hair cutting scraper 3A and the tooth needle 2A is 36 degrees. The straight line formed by the center C1 (C2) of the width of the scraper 3A (pin 2A) on the peripheral surface is arranged at an inclination of 36 degrees. The direction inclined at 36 degrees is the cutting direction of the hair. Thanks to the multiple razor blades which are inclined at 36 degrees, the hair can be cut diagonally. Therefore, it is possible to achieve a natural hairstyle that one prefers.

Then, as shown in FIG. 18F , the roller brush portion 6A is rotated from the inner side of the hair, and the hair cutting scraper 3A4 is used to continuously cut the hair along the direction of the tip of the hair. Then, as shown in FIG. 19G , the roller brush portion 6A is rotated from the inner side of the hair, and the hair cutting scraper 3A5 is used to continuously cut the hair along the direction of the tip of the hair.

Then, as shown in Fig. 19H and Fig. 19I, the operation of cutting the hair along the direction of the tip of the hair is finished. As a result, as shown in Fig. 20A and Fig. 20B, the tip 50b of the hair 50a can be neatly cut obliquely.

In the case of the conventional scissors, the hair 50a is cut in a straight line as shown in Fig. 20C and Fig. 20D.

In this way, according to the hair clipper of the third embodiment, the tooth needles 2A and the hair cutting scraper 3A provided with the razor 36 are arranged alternately at approximately equal intervals throughout the entire circumference of the roller brush portion 6A, and the hair cutting scraper 3A and the hair cutting scraper 3A The angle formed by the tooth needle 2A is approximately 36 degrees, and each of the hair cutting scraper 3A and the tooth needle 2A is inclined by approximately 36 degrees relative to the straight line formed by connecting the center O of the roller brush portion 6A and the center of the width of the respective circumferential surfaces. It is arranged in a horizontal direction, and the direction inclined at about 36 degrees is the direction of cutting hair.

Therefore, by holding the hair in hand and rotating the roller brush 6A from the inside, the hair is combed with the plurality of pins 2A, and the plurality of razors 36 are arranged at an inclination of 36 degrees, whereby the hair can be cut obliquely bit by bit. Therefore, it is possible to achieve a natural hairstyle that one prefers.

Also, by displaying the rotation direction mark 12 representing the rotation direction of the roller brush portion 6A when cutting hair on the roller brush portion 6A, the roller brush portion 6A can be rotated in the rotation direction indicated by the rotation direction mark 12, thereby making it possible to use A plurality of razors 36 gradually cuts the hair bit by bit while slanting.

Moreover, the roller brush part 6A can be attached to a cylinder by fitting the 1st recessed part 70 formed in the cylinder body 7B of the holding part 7a with the 1st convex part formed in the cylinder body of the roller brush part 6A.

Also, by fitting the L-shaped second protrusions 10a, 10a of the cover 10A connected to the fixing portion 10 into the L-shaped second recesses 71, 72 formed on the cylinder 7B of the holding portion 7a, And the 2nd convex part 10a, 10b is rotated, and the roller brush part 6A can be fixed to the holding part 7a.

Furthermore, the present invention is not limited to the hair clipper of the third embodiment. Also, the hair clipper may be provided with: a roller brush portion 6B, which is provided with hair cutting scrapers 3A provided with razors at approximately equal intervals throughout the entire circumference of the circumferential surface, and is equipped with 10 rows of hair cutting scrapers 3A, and the razors 36 of each row are arranged along the One is arranged in the longitudinal direction, and one side is rotated from the inner side of the hair to cut hair with the razor 36; the holding part 7a is installed and holds the roller brush part 6B; and the fixing part 10 is to be installed on the roller brush part of the holding part 7a fixed.

In this case, the angle formed by the hair cutting scraper 3A and the adjacent hair cutting scraper 3A is approximately 36 degrees, and the hair cutting scraper 3A is positioned on the circumference of the center O of the roller brush portion 6B and the hair cutting scraper 3A. The straight lines connecting the width centers C1 on the surface are arranged at an inclination of approximately 36 degrees. The direction inclined at 36 degrees is the direction of cutting hair.

Therefore, the roller brush portion 6B is rotated from the inside while holding the hair by hand, and the plurality of razor blades 36 are arranged at an inclination of 36 degrees, so that the hair can be cut obliquely little by little. Therefore, it is possible to achieve a natural hairstyle that one prefers.
