Electric hair cutting machine, has retainer whose boundary has continuous curvature that is computed such that boundary lies at pin at angle of lever relative to pin in form-fit manner, and lever connecting deflection device with retainer

摘要

The machine (1) has a gearbox (6) transmitting rotational movement of a drive shaft (7) to a movable shaving head cutter (5). A deflection lever (10) connects a deflection device with a retainer (13) for a pin (12) of an eccentric (8). The pin is formed in a direction (15) perpendicular to the drive shaft such that the pin implements up and down movement in the direction. A boundary of the retainer has a continuous curvature that is computed such that the boundary lies at the pin at an angle (18) of the lever relative to the pin in a form-fit manner.
