Abstract
A self-clamping wrench has one fixed clamping jaw, which is rigidly connected to a handle and one mobile clamping jaw, which is mounted thereon in such a way that it can turn. A hand lever is located on the handle on the same side as the mobile clamping jaw. A leaf spring, which is fixed on the hand lever, acts upon the mobile clamping jaw and when the hand lever is closed, forms a tension spring which pushes said clamping jaw into its closed position. When the hand lever is released, the leaf spring acts as a lever spring, which opens the hand lever and the mobile clamping jaw.
