A corkscrew includes a support consisting of a supporting ring adapted to engage a neck of a bottle, and a support bracket connected to the supporting ring. An elongated spindle having a cork-engaging helix at its leading end and a threaded portion at its trailing end is mounted on the support for turning relative thereto and also for longitudinal displacement. A nut engages the threaded portion of the spindle and has handgrip portions, and a locking element embraces the nut and is pivotable relative thereto between a locking position in which it connects the nut to the spindle for joint turning and longitudinal displacement, and an unlocking position in which it releases the spindle for longitudinal displacement during the further turning of the nut. The locking element has an actuating portion which engages an abutment surface of the support when the helix has penetrated into a cork to the desired extent, the engagement of the actuating portion with the surface pivoting the locking element into its unlocking position whereupon the cork is drawn out of the bottle. A biasing arrangement, such as a torsion spring, is interposed between the nut and the locking element, urging the latter towards its locking position. The supporting ring has an elastic lining which contacts the neck of the bottle. |
