Abstract
Un portabrocas perfeccionado, caracterizado por que la pieza base de trabajo, actuando de soporte a los medios de sujeción de la herramienta, presenta una canal helicoidal de sección semicircular, con dos entradas o filetes, que sirve de guía a una bola que hace una función de tuerca, produciendo la elevación del portabrocas y cierre de las garras.
