It is very easy to use.

Nose hair shavers generally include nose hair scissors, a manual rotating nose hair shaver, and an electric hair shaver. Nose hair scissors use round-shaped scissors to prevent them from sticking inside the nose, and the most problematic problem when cutting with these scissors is that the cut nose hair may be scattered from inside the nose or sucked inward when breathing. In use, the clipped nose hair is contained inside the fixed blade.

Manual rotary nose hair shaver, US patent U.S. PAT 5,655,301 U.S. PAT D376,670 has a handle for turning the rotary blade at the lower end of the cotton razor body and a manual rotary blade with a number of cutting blades protruding sharply forward so that the nose is inserted in the upper part. The blade may hurt the inside of the nose, so be very careful when using it. In addition, it is more inconvenient to use than one-handed operation because both hands must be used, as one hand must hold the center of the body and the other hand must turn the rotary knob on the lower end of the body.

In addition, the nose hair shaver composed of the electric motor is often inconvenient to change the battery and noise is high in use, and it is expensive, and it is necessary to make the nose hair powder by breathing at high speed unnecessarily. There is a tendency.

By pushing the rotary knob to the side using only the thumb of the hand, the rotary blade rotates to cut the nose hair, and the rotating blade reverses by the elastic torsion spring means so that the nose hair can be cut again. It is.

First of all, in order to achieve this purpose, in order to simultaneously hold and rotate with one hand, the configuration of the manual rotary nose shaver must be ergonomically matched according to the structure and function of the hand. If the rotary knob is located at the bottom of the manual rotary nose shaver, it cannot be operated with one hand and two hands must be used. Therefore, the rotary knob for turning the rotary blade of the nose hair must be brought directly under the rotary blade, and the lower part of the body forms a grip part that can be held by only one hand, so that the thumb is simply moved while the nose hair is held by one hand. The purpose of cutting the nose hair can be achieved by rotating the rotary blade. Therefore, the present invention has an object to maximize the ease of use in ergonomics in the construction of the device, to achieve an extremely simple structure in the economical and constitution with no consumables.
