The invention relates to a portable cork-screw provided with conventional spiral extraction means (1) which is hinged by means of a pin (4) to a planar part (2) constitutive of the cork screw body, in a position displaced towards one of its ends, the part being provided with two recess (5, 6) in opposite edges; one recess (5) is proximate to the articulation of the spiral (1); a second part (3) is hinged to the end of the part (2) which is closer to the pin (4); the second part (3) is formed by a first cylindrical portion (3a) which is hinged at a first end to the part (2) by means of a pin (7) and is rotationally joined by its other end to a second cylindrical portion (3a); the final section of said second portion is lowered to form a first curved portion having the shape of a tile; said first portion (3a) has a longitudinal opening which is slightly longer than the distance existing between the recess (5) and the hinge pin (7) of the second part (3).
