Abstract:
1. A screw lid opener comprising: a handle; a clamping device for holding a screw lid in place, and having three clamping jaws for clamping down on a screw lid, the clamping jaws being arranged at a distance with respect to a center between the clamping jaws, wherein at least one of the three clamping jaws is movable such that its distance from the center can be changed; a guide disk that has a linear guide slit and is connected to the handle, and a displacement disk that is rotatable with respect to the guide disk and has at least one helical guide element; wherein the movable clamping jaw is arranged on a clamping jaw support, the clamping jaw support being movably seated in the linear guide slit of the guide disk; wherein the clamping jaw support has a guide element, which engages the helical guide element on the displacement disk; the clamping jaw support acts together with the displacement disk, which can be rotated with respect to the guide disk, such that the distance to the center can be changed by relative rotation between the displacement disk and the guide disk; and wherein the helical guide element is substantially flat in areas in which the clamping jaws are a suitable distance from the center for being able to grip a defined lid radius such that jamming occurs between the helical guide element and the guide element of the clamping jaw support.
