Extractor device, constituted by a bridge, in the center of which is screwed a perpendicular screw, finished in attack point, characterized by the fact that, at each end of the bridge, there is a configuration in fork, open towards said end, and of sufficient depth to allow a sliding adjustment, housed in each of said fork shapes a threaded pin, extension of an extractor claw, which, thus, is slidable to a certain extent longitudinally on the carrier bridge, leading to the other end a U-shaped piece against which the nut that carries each bolt of the aforementioned is tightened, so that, with sufficient tightening, each claw is immobilized at the convenient distance of the central spindle.
