A tool bit chuck for drilling and chiseling bits has an axially extending receiving sleeve with an opening therethrough in which latching elements are radially displaceably supported. The latching elements are radially displaceable by a spring loaded axially displaceable actuating element. An actuating sleeve laterally encloses and is axially displaceable relative to the receiving sleeve. Connecting members fix the actuating sleeve to the receiving sleeve. The actuating sleeve has a stop cooperating with the actuating element for applying an axial force to the actuating element for assisting in centering the drilling or chiseling bit.
Cette invention concerne un mandrin de perceuse ou de burineuse comportant un manchon porte-outil axial ayant une ouverture dans laquelle se logent des éléments de verrouillage mobiles dans le sens radial. Le déplacement radial desdits éléments se fait au moyen d'un actionneur à ressort à mobilité axiale. Un manchon de commande enserre le manchon porte-outil et se déplace axialement par rapport à celui-ci. Il est monté sur le manchon porte-outils au moyen de connecteurs et comporte une butée qui applique à l'actionneur une poussée axiale favorisant le centrage de la mèche ou du burin.
