Abstract

1.wrench nut, characterized by being formed from a nut cup whose upper base extends into a cylindrical neck ending in an end portion that determines a polygonal crown whose diagonal has the same length as the diameter of the base cylinder, as well as concentrically with the assembly emerges above the crown a shank, also cylindrical, but of smaller radius than the base cylinder, all of which is suitable for inclusion in a body or cap of axial internal configuration in perfect structural antagonism with the external configuration of the primary neck of the key cup, and whose total height coincides with that of the neck, formed by the cylindrical area and the polygonal end, so that both parts are joined together by tongue and groove forming a whole, protruding the cylindrical end rod of smaller radius above the upper base of the bushing, this actuating arm or lever having this. 2.wrench wrench, according to claim 1, characterized in that the rod that emerges above the upper base of the cap or key body formed, is capable of being coupled tightly and securely, but not fixed, to facilitate the replacement of the vessel precise in each moment, in a knob of manual manipulation, which also allows the positioning for disposition of use of the assembly, either through direct access and action on the knob or on the lever, being in this last position perfectly connected the bushing with the neck of the key cup, provided to ensure the tightness of the position as well as a perfect fit of both bodies, without there being any possibility of adjustment without mediating previous intention, which in the length of the stem or primary neck of the vessel there is coupled a pressure element acting directly on the inner wall of the bushing in any position thereof.
