Abstract

Drillschrauber sind mit einem Griffgehäuse und einer mit ihrem einen Ende darin axial verschieblich gelagerten und über einem Umstellmechanismus zugleich links- oder rechtsdrehend antreibbaren Drillspindel (4) versehen. Diese trägt an ihrem anderen Ende eine Werkzeugaufnahmehülse (7), in der sich eine Mehrkant-Einstecköffnung (15) sowie Haltemittel für das mit einem entsprechend mehrkantig profilierten Schaft (14′) versehene Werkzeug (14) befinden, wobei die Werkzeugaufnahmehülse (7) außen von einer drehbeweglich auf ihr lagernden Handführungshülse (9) gegeben ist. Drill drivers are with a handle housing and one with one end axially slidably mounted therein and at the same time left or over a changeover mechanism Provide clockwise drivable drill spindle (4). These carries a tool holder sleeve at its other end (7), in which there is a polygonal insertion opening (15) and Holding means for that with a correspondingly polygonal profiled shaft (14 ′) provided tool (14), wherein the tool holder sleeve (7) outside of a rotatable hand guide sleeve (9) given is.

Um eine noch stabilere zentrierende Halterung des mehrkantig profilierten Werkzeuges, insbesondere von ent­ sprechend beschaffenen Schraubereinsätzen (14), in der Werkzeugaufnahmehülse (7) zu erzielen, sind an deren vorderem Ende achsparrallel verlaufende Spannzungen (11) als Haltemittel vorgesehen, die mit Außengewinde (11′) versehen sind, auf dem eine gemeinsame Spannmutter (13) sitzt. Vorteilhaft besitzt die Werkzeugaufnahmehülse (7) noch einen sich an die Mehrkant-Einstecköffnung (15) der Spann­ zungen (11) anschließenden Aufnahmehohlraum (16), des­ sen axiale Länge ein Mehrfaches der Länge der Mehrkant-­ Einstecköffnung (15) beträgt. Dadurch können auch Doppel­ werkzeuge (14) eingespannt werden. For an even more stable centering bracket of the polygonal profiled tool, especially from ent speaking screwdriver bits (14), in the To achieve tool holder sleeve (7) are on their front end axially parallel clamping tongues (11) provided as a holding means with an external thread (11 ') are provided on which a common clamping nut (13) sits. The tool holder sleeve (7) advantageously also has one on the polygonal insertion opening (15) of the instep tongues (11) adjoining receiving cavity (16), the axial length is a multiple of the length of the polygonal Insert opening (15). This can also double tools (14) can be clamped.
