Abstract

Adjustable pliers-pliers, of which has a pair of crossed members with a rotating unión between them comprising a bolt in one member and a hole torn in the other that receives the bolt in a sliding manner and avoids the lateral deviation of said member with relationship to the other transversely to the torn hole but allowing the free movement of the first member relative to the other in longitudinal direction to the torn hole and with jaws in the members displaced or projected towards one side of the center line of a tear hole, characterized in that said the rotating unión comprises an arched rib in said first member and a plurality of grooves with open ends in the other member that extend transversely to the torn hole and are separated from each other by walls of decreasing thickness toward both sides of the center line of the member. Ripped hole, because the arched nerve is centered respect to a bolt and the grooves cent with respect to the central line hole, in that said rib is housed in any of the slots to provide a connection between the members that support the working pressure of a jaws; because the rib and the groove in which the rib is lodged have hooking surfaces under the working pressure substantially in the same radius and lowered at an angle which causes both coupling surfaces to be joined under the working pressure and because the angle of recess of the engagement surface of the rib is greater than the recess angle of the engaging surface of the slot, to translate the working pressure towards the bottom of the wall separating the slots.
