  • Patent number: 6752041
    Abstract: In an electric corkscrew, a power switch controls supply of electric power from an electric power source to a motor unit so as to drive an auger to rotate in a positive direction for screwing into a cork that is to be unplugged from a bottleneck or a negative direction for screwing out of the cork that was unplugged from the bottleneck. A control switch interrupts electrical connection between the electric power source and the motor unit when actuated by the cork in a cork passage defined by a sleeve body in a grip member while the cork extends out of the cork passage as a result of rotation of the auger in the positive direction.
