Abstract

La invención se refiere a un mandril de sujeción para herramientas giratorias con un eje de sujeción cilíndrico (2) dentro de un cuerpo base (4). Un orificio de parte a parte (7) en el cuerpo base (4) que actúa sobre un miembro de presión (9) introducido entre el eje de sujeción (2) y el tornillo de sujeción del orificio (7). El miembro de presión (9) tiene un saliente radial (16) y el orificio contiene una cruceta transversal de estrechamiento (17) en su extremo interior. Un elemento elástico compresible (18) actúa entre el miembro de presión (9) y el orificio (17). La fuerza de retorno de dicho elemento elástico le permite alzar el miembro de presión (9) desde el eje de sujeción (2) cuando el tornillo de sujeción no está engarzado y lo empuja hacia atrás, dentro del orificio (7)
