Abstract: A self hair cutting or trimming device comprises an elongated handle housing an electric drive, the drive comprises an elongated spool mounted coil connected in series with a diode. An elongated core is mounted through the coil and connects a movable blade in sliding contact with a fixed blade projecting from the forward end of the handle. Within the backward end of the handle a plastic bolt is threadedly received to adjust the position of the core, and thereby the movable blade, through a spring disposed in between the bolt and the core.

Abstract: This invention concerns about an electric hair comb-clipper. It mainly uses a magnetism generator which, by its two magnetic poles, changes the polar of the two poles when AC current is on, enabling the swing block with two poles to swing up and down forcing a movable clipper blade to move back and forth straight as well. Below the movable blade, a comb is attached to the base for combing hair; after hair has been combed by the comb, the base is turned around for 90 degrees to have hair cut off by the movable blade.
