[0002] A nose hair trimmer is a commonly used daily necessity that can quickly and safely trim excessively long nose hairs in the nasal cavity.

[0003] In the nose hair trimmer, the inner blade plays a very important role. The working part of the inner blade is the upper part of the cutting edge (attached Figure 4 The red part a) in the middle circle is used to make the inner blade edge close to the outer blade through the spring pressure, and then the inner blade assembly (referring to the combination of the inner blade and the spring) is driven by the whole machine motor to rotate to achieve shearing. One of the most important functional indicators of the product is sharpness, and the gap between the inner blade and the outer blade (hereinafter referred to as the gap) is an important factor affecting sharpness. The existing technology is a single spring structure, and the spring action point is a distance away from the working edge of the inner blade. This causes the inner blade to have poor stability after shearing force during high-speed rotation, causing the gap to change, thereby affecting sharpness. Utility Model Content
