Pliers, with two arms that are joined together via an articulation pin. One of the arms has a protuberance with a lateral channel that extends via one of the orifices, a pusher being located in the channel and having an inner channel that accommodates a spring that acts between the pusher and the arm. The articulation pin is joined by means of screwing to the pusher in the region of the lateral channel, a toothed claw being arranged coaxially therebetween with mechanical continuity. The pusher is continued as an extension located on the walls of the other orifice in the work position. Applicable to hand tools. |
