Abstract

Eine längs einer Schlagachse (A) zumindest teilweise schlagende und drehende Handwerkzeugmaschine mit einem bezüglich einer vibrierenden Schlagwerksbaugruppe (2) vibrationsentkoppelten Führungshandgriff mit einem Motorschalter zur Motorsteuerung, dem zur Arretierung ein Arretierschalter (7) zugeordnet ist, der in einem Schaltbereich (X) versetzbar ist, wobei in der Schlagwerksbaugruppe (2) ein Betriebsmodiwahlschalter (2) angeordnet ist, der ein Schaltgestänge (9) versetzt, das einen Anschlag (10) aufweist, der in einem drehenden Betriebsmode in den Schaltbereich (X) hineinragt, wobei das Schaltgestänge (9) abgewinkelt mit zwei Schenkeln (16a, 16b) ausgebildet ist, wobei ein biegesteifer Schenkel (16a), der den Anschlag (10) ausbildet sowie in einem Drehschwenkpunkt (17) an der Schlagwerksbaugruppe (2) verschwenkbar gelagert ist, und der andere mit dem Betriebsmodiwahlschalter (3) verbundene, sich axial erstreckende Schenkel (16b) biegeschlaff ausgebildet ist.

Figure imgaf001
A longitudinally of a striking axis (A) at least partially beating and rotating hand tool with a respect to a vibrating percussion assembly (2) vibration-decoupled guide handle with a motor switch for engine control, which is assigned to lock a locking switch (7) which is displaceable in a switching range (X) , wherein in the striking mechanism assembly (2) a Betriebsmodiwahlschalter (2) is arranged, which displaces a switching linkage (9) having a stop (10) which projects in a rotating operating mode in the shift range (X), wherein the shift linkage (9 ) angled with two legs (16a, 16b) is formed, wherein a rigid leg (16a) which forms the stop (10) and in a pivot point (17) on the striking mechanism assembly (2) is pivotally mounted, and the other with the Operating mode selector switch (3) connected, axially extending legs (16b) is formed slippery.
