Description

A kind of hair scissors cutter head of adjustable hair-cutting length and adopt the hair scissors of this cutter head
Technical field
The utility model relates to personal-care supplies technical field, is specifically related to a kind of cutter head of hair scissors of adjustable hair-cutting length and adopts the hair scissors of this cutter head.
Background technology
Traditional various hair scissorses, as shaver, vibrissac scissors or other small-sized hair scissorses for personal daily cleaning-nursing, all have fixing structure, can cut the hair of regular length, can not regulate the length of hair-cutting.But, in actual use, such as: for the push broach of getting a haircut, often to be used for the hair of the different length cutting different people, change push broach or cutter head if frequent, can cause using inconvenient, and configure multiple cutter head or push broach due to needs, can waste be caused.
The cutter head of the hair scissors of current main flow all comprises moving knife and stationary knife, and stationary knife is motionless, and moving knife is driven by the drive unit in blade, moves left and right thus cut off by hair relative to stationary knife.Because hair stretches into from the outer surface of stationary knife, then cut off by the moving knife of the inner surface being positioned at stationary knife, so the thickness of stationary knife just determines the length shearing hair.As shown in Figure 1, usually the outer surface of stationary knife 200 is made smooth cambered surface, it is gradually thinning to one end that it is provided with cutter tooth by stationary knife blade surface, make the side being provided with one end of cutter tooth of stationary knife 200 or cross section triangular in shape, if moving knife can be moved from inside to outside, in other words, moving knife 100 is moved to the edge direction being provided with cutter tooth of stationary knife 200 by the edge being provided with cutter tooth away from stationary knife, the length that just can realize shearing hair is shortened by long, as depicted in figs. 1 and 2, h1 and h2 be the hair-cutting length of corresponding moving knife 100 when two positions respectively, obviously, h1 corresponding to h1 is larger than h2.
In recent years, market also occurs the cutter of the adjustable hair-cutting length of a class is cut, but all adopted monolateral adjustment, namely regulated respectively on the both sides of cutter head, uneven about easily causing moving knife, and effectively can not accomplish the effect of finely tuning hair-cutting length.
