Abstract
Improved wrench for nuts, which is essentially characterized by being constituted by a flat metallic body comprising a properly shaped handle, at one end of which there is a mouth with two jaws, one of which has a straight internal part, while in the other appears a straight area that ends with a perpendicular tooth, whose two straight parts are divergent towards the outside of the key and are joined at the bottom by two small straight sections and an intermediate concave arch, in such a way that the aforementioned straight parts they form a certain theoretical acute angle whose bisector passes through the center of the said incoming arc, the center of an ideal circle coinciding thereon coinciding with three points determined by the end of the jaw completely straight, the internal vertex of the tooth and the center of the concave arch, which achieves a profile of complete mechanical adaptation to any type of your ercas, in the jaw alluded to in the first place a convex curved part for support of the thumb and in the extremity opposite the working mouth a hole for suspension of the tool.
