Corkscrew

A corkscrew for the extraction of a cork from a neck of a bottle, the corkscrew comprising a body provided with a first end and with a second end, an extraction screw hinged at a pivot point which is placed between the first end and the second end, the extraction screw being suitable for insertion by screwing within the volume of the cork, an articulated lever hinged at a fulcrum point near the first end, the articulated lever comprising a first lever and a second lever coupled with each other by a coupling system wherein the coupling system is configured to enable a reciprocal movement of the second lever with respect to the first lever, the articulated lever being provided with a first propping tooth placed on the first lever and with a second propping tooth placed on the second lever, the first and the second tooth being suitable for propping the corkscrew on the neck of the bottle characterized in that the coupling system between the first lever and the second lever comprises at least two sets of slots, at least one set of pins, and at least one set of holes, wherein the pins pass at least through the holes and the slots fixing the first lever and the second lever to each other in such a way that the second lever is a prolongation of the first lever, the pins being slidably engaged in respective slots in such a way that the reciprocal movement of the second lever with respect to the first lever is a movement that occurs in a guided condition by means of the pins, the reciprocal movement of the second lever with respect to the first lever being constrained by sliding paths which are defined by the set of slots within which the respective pins are slidable and wherein the two sets of slots extend in different directions on the first lever.
