Abstract
The invention relates to an open-end wrench having a clamping jaw which is rigidly connected to a wrench handle in a fixed manner. A spring-loaded, moveable clamping jaw is pivotally mounted on the fixed clamping jaw. A recess, which recoils opposite the plane of the clamping surface, is connected to the clamping surface of the fixed clamping jaw on the gripping side. The moveable clamping jaw has a recess located in the area between the clamping surface of the jaw and the pivot point thereof. In an opened state of the wrench, said recess approximately corresponds to the recess behind the fixed clamping jaw. The wrench can be handled similarly to a fixed open-end wrench, whereby it enables a ratcheting action and has a self-clamping operation.
