Sie Erfindung besieht sich, auf ein Schnellwechselfutter auf einer Maechinenspindel, (vorwiegend einer SLektrohandbohrmaechine] gemäß dem Oberhegriff dee Anspruches 1The invention relates to a quick-change chuck on a machine spindle (primarily an electric hand drill) according to the preamble of claim 1

Bei den handelsüblichen Handbohrmaschinen hat sich als nachteilig erwiesen, daß von diesen angetriebene Werkzeuge jeweils durch lösen und spannen des Bohrfuttere ausgewechselt werden ( ) können.A disadvantage of commercially available hand drills has been that the tools driven by them can be exchanged by loosening and tightening the drill chuck ( ).

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Werkzeug schnell wechseln su können.The present invention is based on the object of being able to change the tool quickly.

Diese Aufgabe wird dadurch gelöst, daß zwischen den Bohrfuttern und der Maoohikenepindel ein Sohnellwechselfutter angeordnet 1st und daß das Schnellwechselfutter auf seiner der Maschinenspindel zugeordneten Seite ein in das Bohrfutter passendes Einsatzstück hat.This task is solved by arranging a quick-change chuck between the drill chuck and the machine spindle 1 and by the quick-change chuck having an insert piece that fits into the drill chuck on its side associated with the machine spindle.

Durch das Schnellwechselfutter ist es möglich, dac Werkzeug schneller als bei der Verwendung eines Bohrfutters zu wechseln.The quick-change chuck makes it possible to change the tool faster than when using a drill chuck.

Die Ansprüche 2-5 betr. die bevorzugte Bauform der Erfindung. OClaims 2-5 relate to the preferred design of the invention. O
