US Patent 11104017 Hair cutter blade gap adjustment system

A hair cutting system includes a handle defining a longitudinal axis, a strut mounted to the handle and a hair cutting blade assembly coupled to the strut. The cutting blade assembly includes a stationary blade defining cutting teeth having blade edges and a movable blade defining cutting teeth having blade edges and capable of reciprocal movement relative to the stationary blade in a horizontal direction. The movable blade and the stationary blade are movable relative to each other in a longitudinal direction to adjust a longitudinal position of the movable blade relative to the stationary blade to selectively vary a distance between the blade edges of the stationary blade and the blade edges of the movable blade. A releasable lock is configured to selectively lock and release the stationary blade and the movable blade with respect to each other in the longitudinal direction.
