A power-operated tweezers device for plucking hairs includes a reciprocatable member coupled to a motor, tweezers, a lost-motion coupling between the reciprocatable member and the tweezers effective to move the tweezers to an extended position only during a first part of the forward stroke of the reciprocatable member, and to a retracted position only during a first part of the return stroke of the reciprocatable member; and means effective to move the tweezer jaws to their closed positions during a last part of the forward stroke of the reciprocatable member, and to their open positions during a last part of the return stroke of the reciprocatable member. |
