    Abstract: An improved shearing blade module of an electric clipper comprises an upper blade and a lower blade; the lower blade is fixed, and the upper blade is comprised of a swaying member capable of swaying sideway in the housing of the electric clipper, such that the blades of the upper and lower blades define the shearing action; the lower blade has a metallic main body, and a hard vacuum coated film is disposed on the surface of said main body; said upper blade has a main body with both volume and area smaller than those of the lower blade, and said main body is made of ceramics. Combining the excellent properties of the ceramic material and the hard multiplayer film, the blade module enhances the heat resistance, wear resistance, and sharpness of the blade sections of the upper and lower blades.
