Abstract: A blade structure of an electric hair trimmer is a blade set, comprising a fixed blade, a movable blade and a vibration seat which is driven by a motor. A front end of both fixed and movable blades is provided with a plurality of teeth to cut the hair by an alternate movement. The lower sections of edge parts at two sides of a tooth of the movable blade are extended outward from top to bottom to form with externally expanded surfaces with sharp transection angles. Accordingly, when hair is cut, a contact area of the edge parts between the hair is decreased, to largely reduce resistance to cutting, such that the hair can be cut off well with improved speed and efficiency and can be prevented from being damaged. Besides, lifetime of usage of blade structure in the electric hair trimmer can be extended.

The first distance is determined according to a mechanical tolerance of the diffuser plate. Movement of the diffuser plate along a direction of a second centrosymmetric line perpendicular to the first centrosymmetric line, is constrained by the positioning portion. The receiving portion and a positioning portion may comprise a fixing hole and a positioning pin. Alternatively, the receiving portion and the positioning portion comprise a fixing groove and a positioning piece.
