Abstract

Portabrocas, del tipo que comprende un cuerpo base en el que en taladros dirigidos oblicuamente respecto al eje de rotación, están guiadas deslizantes garras de sujeción, y sobre el que está alojada rotativa en una ranura anular una tuerca de anillo que circunda al cuerpo base y engrana en partes de rosca de las garras de sujeción para adelantar o retrasar las garras de sujeción, llevando la tuerca de anillo en su extremo del lado herramienta un dentado cónico, con el que pueden engranarse los dientes de una lleva de portabrocas especial para aflojar o apretar las garras de sujeción, estando desarrollada la tuerca de anillo en mitades que están sujetas mediante un casquillo que las abraza y estando cerradas o bien siendo ciegas los huecos del dentado cónico en su extremo interior, caracterizado porque la longitud axial de la tuerca de anillo es igual que la extensión axial de los hilos de rosca.
