The electric hair clipper blade set currently on the market is composed of a fixed blade and a movable blade. The movable blade is driven by an electric motor to fit the fixed blade and reciprocate left and right to cut the hair like scissors. The rapid reciprocating friction between the fitting surface of the movable blade and the fixed blade will aggravate the wear of the blade base material and seriously affect the service life of the blade. At the same time, a large amount of heat is generated, causing the blade temperature to rise, making the user's skin feel hot, seriously affecting the user experience.

In view of this, the present invention is proposed.

Summary of the invention:
