Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field 2) This invention belongs to the field of cutting hand tools, and is mainly used as a razor-shaped rattle tool.

(Conventional technology) There are two types of razor-shaped rattle tools that have been used in the past: those with the cutting edge completely exposed and those with the cutting edge stored in a holder and exposed intermittently, but the former is dangerous. However, the latter is popular because it is highly safe and does not touch the cutting edge even if you grip the holder with force. Since the shape of the part is an isosceles triangle with a sharp apex angle, the guiding width of the hair bundle to be sheared is narrow, which improves processing efficiency.
When shearing, you are forced to press down while shearing, so the cut end is not sharp and the surface of the hair is scraped, damaging the hair.In addition, it causes split ends that are difficult to settle and become difficult to handle. It had inherent flaws that caused harm.

(Problems to be Solved by the Invention) In view of the above-mentioned circumstances, the technical object of the present invention is to provide a rattle tool that can minimize the area of the cutting surface and perform shearing without damaging the hair quality.

(Means for Solving the Problems) The present invention provides a cutting hand tool in which a cutting tool for hair shearing is built into a holder and the cutting edge is intermittently exposed within the cutting section, and the cutting section is cut out at the lower end of the holder. Longitudinal front side notch 1
The surface is a substantially vertical surface, and the notch surface is an angle W545° with respect to the vertical surface, and an inclined surface continuous from the upper end of the vertical surface to the lower end at Iv, and the front and rear surface periphery of the cut portion is provided as appropriate. A chamfered guide surface is provided on the holder, four recesses are provided on the front surface of the upper part of the holder that are sufficient to hold the thumb, and appropriate waves are provided in the vertical direction below the grip part that is integrated with the holder. It is made up of Here, the term "substantially vertical plane" means that the front side notch surface is slightly inclined rearward from the upper end to the lower end.

(According to the above structure, the hair guided to the cutting part is sheared sharply by the cutting edge on the vertical plane of the cutting part by pushing the holder forward in an arc shape. At this time, the holder itself can be cut by hand. It is held securely without slipping.

(Example) To explain this invention in detail with reference to an example, as shown in FIG. The side notch surface is an inclined surface 6 continuous from the upper end 4 to the lower end 5 of the vertical surface 3 at an angle of 45 degrees with respect to the vertical surface 3, and the front and rear surfaces 1i1 edges of the notch lFr portion 2 are chamfered as appropriate. A fixing device 8 built into the holder 1 is fixed at a position where its cutting edge 9 is intermittently exposed within the cutting section 2 as shown in FIG. The upper front surface of the holder 1 is provided with a recess 10 for locking the thumb, and below the grip 11 integrated with the holder 1 is a wave 12 for locking the finger.
Note that the present invention is not limited to the type in which the holder 1 is opened to the leek sea bream as shown in the embodiment, but can also be applied to a type having a groove for insertion from the front. , of course, can be done.

(Effects of the Invention) As described above, according to the ratchet according to the present invention, not only safety is ensured, but also the hair guided to the cutting part can be pushed down on the holder in an arc shape to align it with the vertical surface. Since the cut surface is sheared to a minimum, there is very little damage to the hair, and the hair remains healthy after shearing.
Along with rero, it has the effect of making it easier to perform cosmetic hair treatments.

Claims (1)

[Claims] A cutting hand tool comprising a cutting tool for hair shearing built into a holder and a cutting edge intermittently exposed within the cutting part, wherein the cutting part cut out at the lower end of the holder has a notch surface on the front side in the longitudinal direction as a substantially vertical plane, The rear notch surface is an inclined surface continuous from the upper end to the lower end of the vertical surface at an angle of approximately 45° with respect to the vertical surface, and a guide surface formed by chamfering the front and rear surfaces of the cut portion as appropriate. The hair cutting tool is provided with a recessed portion sufficient to hold the thumb in the front surface of the upper part of the holder, and appropriate waves are provided in the vertical direction below a grip portion integrated with the holder.
