Abstract: The invention relates to a wall-mounted corkscrew comprising a mechanism which includes the helical shaft to be inserted into the cork and which is connected to an actuating lever. The aforementioned mechanism is housed inside a one-piece tubular body which is closed at one end and said mechanism comprises a plastic cylindrical part (15) in which a helical-shaft-bearing screw (2) is positioned with an axial freedom of movement. In addition, a backstop is disposed between a striction (7) inside the part (15) and a transverse shaft (8) which passes therethrough.
