Automatic Corkscrews

Automatic Corkscrews are so called because the action of the worm entering the cork is the same action that removes the cork.

Usually, the corkscrew housing is similar to a bell housing. The worm goes in until the edge of the bell rests against the lip of the bottle. At this point the housing stops going down, and continuing the turning of the worm causes the cork to pull up and out.

Three typical automatic corkscrews are shown below.
