Claims (6)

1. 1. A rotary type body hair cutter is characterized in that, Comprising the following steps: a holding part; A first cutting part limited on the upper side of the holding part and having a first cutting edge formed on the upper end thereof, and A second cutting part inserted to the outside of the first cutting part, the inner peripheral surface being combined with the holding part, a second cutting edge being formed at the upper end to mutually rotate with the first cutting edge to cut the body hair, The grip portion includes: a holding body part on which the first cutting part is disposed at the upper side, and A protruding coupling part which is limited on the upper side of the holding body part and protrudes along the outer peripheral surface of the first cutting part, the second cutting part is fastened in a forced buckling mode in a mode of enabling the second cutting part to be separated, the second cutting part is limited in a mode of enabling the second cutting part to rotate, The protruding coupling portion protrudes along the outer circumferential surface to form a fastening portion coupled with the inner circumferential surface of the second cutting portion so that the second cutting portion is inserted and fastened by a forced-locking manner, The fastening part forms a first inclined surface and a second inclined surface at the upper side corner and the lower side corner in a manner that the second cutting part can be assembled and disassembled, The second cutting part protrudes along the inner peripheral surface to form a fastening part which is fastened with the fastening part so as to be fastened at the protruding joint part and then is limited in a rotatable manner, The buckling part forms a first conical surface at the upper side corner and a second conical surface at the lower side corner, so as to be assembled with or separated from the protruding joint part in a forced buckling way, The protruding coupling portion is formed with at least one slit, and when the second cutting portion is separated from the protruding coupling portion, the first tapered surface is brought into close contact with the second inclined surface and a part of the protruding coupling portion is elastically deformed inward in a radial direction, and when the second cutting portion is coupled to the protruding coupling portion, the second tapered surface is brought into close contact with the first inclined surface and a part of the protruding coupling portion is elastically deformed inward in a radial direction and returns to an original outward position.
2. 2. A rotary hair cutter according to claim 1, wherein a plurality of said slits are formed at equal intervals along the periphery of said protruding coupling portion.
3. 3. The rotary hair cutter according to claim 1, wherein the grip portion further comprises an anti-rotation protrusion protruding from an outer peripheral surface of the grip body portion so as to restrict rotation from a bottom surface.
4. 4. The rotary hair cutter according to claim 1, further comprising a cover portion inserted to the outside of the second cutting portion and detachably coupled to the holding body portion so as to be able to selectively open and close the first cutting portion and the second cutting portion.
5. 5. The rotary hair cutter according to claim 4, wherein the cover portion is coupled to the holding body portion by a groove or a protrusion structure or by screw-coupling.
6. 6. The rotary hair cutter as claimed in claim 4, wherein the cover part includes a vent hole to discharge the internal air to the outside when inserted to the outside of the second cutting part.

Description

Rotary body hair cutter Technical Field The present invention relates to a rotary hair cutter with simple separation and assembly. Background In general, there are a plurality of nasal hairs of different lengths in nostrils of a human body, and such nasal hairs function to filter inflow of external dust and the like into respiratory organs of the human body. On the other hand, recently, when nose hair is exposed to the outside from nostrils, it is considered that the nose hair is unhygienic, and various types of nose hair trimmers have been developed, and as an example, the nose hair trimmers may be nose hair trimmers. The nose hair trimming cutter has the problem of simple and convenient application, but cannot confirm that the nose hair trimming cutter has the defect that wounds with different sizes possibly occur in nostrils when the nose hair is trimmed in terms of the structure of the nose hair trimming cutter. Accordingly, in order to solve such a problem, recently, an "electric hair cutter" has been developed, which includes an outer head portion formed with a plurality of outer cutting edges, an inner cutting edge formed with a plurality of inner cutting edges, and a fastening screw for fastening the inner head portion and the outer head portion. When the nose hair is tidied, the electric shaver Mao Qiege improves the stability and convenience of the nose hair trimmer through the structure that the outer side head part rotates from the inner side head part in an electric mode. However, in the case of the above-described electric hair cutter, in a structure in which the inner head portion and the outer head portion are coupled by a fastening unit such as a fastening screw, assembly and separation are troublesome, and there is a concern that the fastening unit is frequently lost when the assembly or separation is performed, and when the fastening unit is lost, the entire product needs to be replaced. Prior art literature Patent literature Patent document 0001 Korean patent laid-open utility model No. 20-0310081 (date of approval: 28 th of 03 month in 2003) Disclosure of Invention In view of the above, the present invention has been made in view of the above-described background art, and an object of the present invention is to provide a rotary hair cutter that can easily couple a first cutting portion and a second cutting portion by a forced-fastening manner without an additional fastening unit, and that can easily separate the first cutting portion and the second cutting portion after use. Further, an object of the present invention is to provide a body hair cutter in which a loss accident can be significantly reduced by forming an anti-rotation protrusion so as to restrict rotation from a bottom surface. The objects of the present invention are not limited thereto, and other objects not mentioned may be clearly understood by those skilled in the art to which the present invention pertains from the following description. In order to solve the above problems, an embodiment of the present invention provides a rotary hair cutter including a grip portion, a first cutting portion disposed on an upper side of the grip portion and having a first cutting edge formed at an upper end thereof, and a second cutting portion inserted to an outer side of the first cutting portion and having an inner peripheral surface coupled to the grip portion and a second cutting edge formed at an upper end thereof and rotatable with the first cutting edge to cut hair, the grip portion including a grip body portion on which the first cutting portion is disposed, and a protruding coupling portion protruding in a circumferential direction along an outer peripheral surface of the first cutting portion on an upper side of the grip body portion, the second cutting portion being rotatably restricted by forcibly fastening so as to be separable. According to the embodiment of the present invention, the present invention has an effect that the first cutting part and the second cutting part can be easily combined by forcibly fastening without an additional fastening unit, and furthermore, the first cutting part and the second cutting part can be easily separated after use. Also, according to the embodiment of the present invention, the present invention has an effect that loss accidents can be remarkably reduced by forming the structure of the anti-rotation protrusion in such a manner that rotation is restricted from the bottom surface. The effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned can be clearly understood by those skilled in the art to which the present invention pertains from the description of the scope of the claimed invention.
