Manual tool, characterized essentially by two curvilinear and symmetrical elements, articulated by their parts of greater curvature, forming separate operating arms, whose central parts serve as articulation to two pieces of grooved configuration, centrally articulated at their other ends, in a point where the end of a central sliding piece that holds the ends of two rods arranged longitudinally with respect to the arms of the tool, is guided by pairs of facing expansions, derived from the heads of the operating arms and finished at parallel ends. That, in the position of rest of the tool, they remain in contact, concurrently concurring with them the analogous ends of other rigid rods located in the heads of the operating arms.
