Abstract: Water pump pliers consisting of two pincer parts crossing themselves in a connecting region, each consisting of a handle portion and a jaw wherein said pincer parts are movably connected in said connecting region in such a way that said first pincer can be displaced relative to the second pincer to adjust a jaw opening-width on the one hand, and that the pincer parts with jaws can reciprocally pivot on the other hand. A blocking means is provided in such a manner that further shifting of the first pincer part is blocked when the jaws stop against a workpiece to be gripped. A spring element is installed between the pincer parts in such a way that a releasing force from the spring, operating in the opening direction of the jaws, acts upon the pincer parts.

Abstract: A pair of water pump pliers, comprising two pincer parts crossing themselves in a connecting region, each consisting of a handle portion and a jaw, wherein the pincer parts are movably connected in the connecting region in such a manner that the first pincer can be displaced relative to the second pincer to adjust the jaw opening width. The pincer parts reciprocally pivot on the other hand, wherein a blocking mechanism is provided in such a manner that further shifting of the first pincer part is blocked when the jaws stop against a workpiece. Also, a spring element is installed between the handle is such a manner that a releasing force from the spring, operating in the jaws' opening direction, acts upon the pincer parts.
