ABSTRACT:
The disclosure is directed to an improved electric hair clipper of a type with a pivotal head portion, having a comb plate for comb-cutting, in which a blade unit is arranged to be slidable for releasable attachment with respect to the head portion, in a longitudinal direction intersecting at right angles with a pivoting direction of the head portion through an engaging and sliding arrangement including sliding projections and corresponding guide grooves in which the sliding projections are fitted for sliding movement, so that no excessive loads are applied to a pivotal axis or pivotal angle restricting portion of the head portion, while the blade unit can be readily detached without having to touch the blade edge with a finger.
