Description

Adjustable auxiliary comb for electric hair clippers

The present invention relates to a pre-selected and variable length hair cutting device, and more particularly to an adjustable auxiliary comb for an electric hair clipper.

Background technique

The electric hair clipper on the market generally has a comb-shaped fixed blade and a comb-like movable blade, and the hair is cut by right and left reciprocating motion of the fixed blade by the movable blade. In order to facilitate the user to control the length of the haircut, some electric hair clippers are provided with an auxiliary comb. The auxiliary comb generally covers the movable edge or/and the fixed edge of the electric hair clipper so that there is a distance between the blade and the hair to cut the hair to a selected uniform length. For example, if the auxiliary comb covers the blade by five millimeters, the hair can be cut to a minimum of five millimeters. The general auxiliary combs are adjustable and the user can select different haircut lengths.

The existing adjustable auxiliary comb structure is controlled by an adjusting device provided in the middle portion of the housing of the electric hair clipper, and the adjusting device is generally pushed into the push button, thereby realizing holding the electric hair clipper with one hand while using one The finger control push button adjusts the auxiliary comb. However, the existing adjustable auxiliary comb structure is complicated and the production cost is also high. Moreover, the length of the cut hair that can be selected is not much, and generally only two to three are selected. In addition, because the general auxiliary comb is not movable and unloadable, it cannot be cleaned and affects hygiene; if the auxiliary comb is damaged, it is difficult to replace, and the entire electric hair clipper must be discarded, which is not in line with environmental protection principles.
