Abstract

Abstract Translated from German Das Handgerät verfügt über einen ohne Hilfswerkzeuge austauschbaren Werkzeughalter (4). Zur Erzielung von Rund- und Planlauf sind am Futterkörper (6) des Werkzeughalters (4) und an der Drehspindel (5) miteinander unter der Kraft einer Feder (11) verspannbar ein Kegelzapfen (27) und eine Kegelöffnung (13) angeordnet. Die Drehspindel (5) ist hierzu mit einer Ausnehmung (28) versehen, die eine geneigte Flanke (29) aufweist, an der sich unter Federkraft ein Spannelement (16) abstützt. Die Feder wird von einer Betätigungshandhabe (9) gespannt. The handheld device has a tool holder (4) that can be exchanged without auxiliary tools. To achieve concentricity and axial runout, a taper pin (27) and a taper opening (13) are arranged on the chuck body (6) of the tool holder (4) and on the rotating spindle (5) under the force of a spring (11). For this purpose, the rotating spindle (5) is provided with a recess (28) which has an inclined flank (29) on which a tensioning element (16) is supported under spring force. The spring is tensioned by an operating handle (9).
