1. An adjustable nut wrench comprising a base element and a sliding element, said base element comprising a handle section extending in longitudinal direction and a first abutment section protruding from the handle section;
and the sliding element comprising a longitudinal sliding section extending parallel to the longitudinal handle section and being slide guided on the handle section, and a second abutment section protruding from the sliding section; and the first and second abutment sections each comprising an abutment surface, and the abutment surfaces being arranged face to face to each other for clamping a nut between the abutment surfaces of the first and second abutment sections and a spring forces abutment surfaces to each other, wherein said abutment surface of the second abutment section is aligned in an angle between 20 and 60 degrees approximately between the abutment surface and a longitudinal direction of the handle section and at least the abutment surface of the sliding section has high level of friction that allows the wrench to be self clamping without any auxiliary locking or suppressing means, and wherein in a case of an external location the first abutment surface the working wrench rotation direction is from the abutment surface to the handle, an opposite direction is idle, and wherein in a case of an internal location the first abutment surface the working rotation direction of the wrench is from handle to the first abutment surface, an opposite direction is idle, and wherein the sliding section can be freely moved by hand or by spring when the wrench is not in the working position. |
