Abstract
A hair clipper has a cutter head on the front end of a housing. The cutter head includes a toothed stationary blade and a toothed movable blade reciprocating on the stationary blade in a hair shearing engagement between individual toothed edges thereof. The movable blade is slidable relative to the stationary blade in an edgewise direction perpendicular to the reciprocating motion of the movable blade for varying a cut length of hairs. An adjuster handle is slidably fitted on an outer round surface of the housing and linked to the movable blade through a linkage member such that the movable blade is shifted in the edgewise direction to increase and reduce the cut length by rotating the adjuster handle about a longitudinal axis of the housing. In addition, the hair clipper can be formed in such a structure that the reciprocating motion of the movable blade is turned on and off at the opposite ends of the rotation range of the adjuster handle. Therefore, the operator is required only to rotate the adjuster handle with a slight manipulation force for initiating the reciprocating motion and then adjusting the cut length.
