The invention relates to a regulating system for opening tools to be applied to opening tools of the compasses type, adjustable spanners (wrenches) or the like, to which its application is possible. The regulator system for opening tools consists of a body 1, a toothed jaw 9, a toothed wheel 5, an eccentric shaft 6, a pressure-regulator handle 17, an ergonomic handle 8, a tie-rod 4 and a return spring 2 for the handle. Operation of the system consists of an ergonomic handle 8 allowing a perfect fit for the hand of the user and the latter's fingers. With the rotational movement of the thumb and index finger on the toothed wheel 5, the necessary adjustment is achieved for opening or closing the toothed jaw 9. The necessary pressure for seizing or blocking the workpiece is achieved by means of an eccentric shaft 6 integral with the fork 7 mounted on the pressure-regulator handle 17, which, when manipulated by the fingers, regulates the pressure for seizing or blocking. <IMAGE>
