The present invention relates to a crokscrew comprising a first and a second body, which second body is connected to a screw. With this arrangement the first body is provided with a screw thread that engages in a complementary screw thread on the second body, in that a blocking element, which has restricted movement, is movably connected to one of the two bodies and is provided with a stop that, at least in a first position of said blocking element, is in contact with a stop on the other body, as a result of which the mutual rotation of the two bodies is blocked, in that in a second position of said blocking element the blocking stop does not engage on the other body and in that during use, once the screw has been screwed a certain length into the cork, the latter moves the blocking element from the first into the second position, as a result of which the mutual rotation of the two bodies is enabled and the second body is moved in a direction away from the cork by turning the first body.
