Abstract

Ein elektrisches Handwerkzeuggerät (2) weist ein Schaltgetriebe (6), das wenigstens zwei Schaltstufen umfasst, ein zuschaltbares Schlagwerk (10) und einen Modischalter (4) auf, mittels dem sowohl das Schaltgetriebe (6) zwischen den Schaltstufen hin- und her schaltbar als auch das Schlagwerk (10) zu- und abschaltbar ist, und der hierzu sowohl mit Getriebeschaltmitteln (16) des Schaltgetriebes (6) als auch mit Schlagwerkschaltmitteln (18) des Schlagwerkes (10) bewegungsgekoppelt ist. Es ist vorgesehen, dass die Schlagwerkschaltmittel (18) einen Schwenkmechanismus aufweisen, der mittels des Modischalters (4) zwischen einer Aktivstellung, in der das Schlagwerk (10) aktivierbar ist, und einer Passivstellung verschwenkbar ist, in der das Schlagwerk (10) deaktiviert ist.

An electric hand tool (2) has a manual transmission (6), which comprises at least two switching stages, a switchable impact mechanism (10) and a mode switch (4), by means of which both the transmission (6) between the switching stages back and forth switchable also the impact mechanism (10) can be switched on and off, and this is coupled in motion with both gear shift means (16) of the gearbox (6) and with Schlagwerkschaltmitteln (18) of the percussion mechanism (10). It is provided that the Schlagwerkschaltmittel (18) have a pivoting mechanism which is pivotable by means of the mode switch (4) between an active position in which the striking mechanism (10) can be activated, and a passive position in which the striking mechanism (10) is deactivated ,
