Abstract
A hand-held electric power tool (2) includes a switching gear unit (6) which has at least two switching stages, including an impact mechanism (10) which can be switched on, and a mode switch (4) with which the switching gear unit (6) can be switched back and forth between the switching stages. The impact mechanism (10) can be switched on and off, and the mode switch (4) is movement-coupled with a gear unit switching mechanism (16) of the switching gear unit (6) and with an impact mechanism switching mechanism (18) of the impact mechanism (10). The impact mechanism switching mechanism (18) has a swiveling mechanism which can be swiveled by the mode switch (4) between an active position, in which the impact mechanism (10) can be activated, and a passive position in which the impact mechanism (10) is deactivated.
Claims10
A hand-held electric power tool (2), comprising:
- a switching gear unit (6) having at least two switching stages;
- an impact mechanism (10);
- and
- a mode switch (4) for switching the switching gear unit (6) back and forth between the at least two switching stages and for switching the impact mechanism (10) on and off, and a switching arrangement (15) having gear unit switching means (16) for connecting the mode switch (4) with the switching gear unit (6) and impact mechanism switching means (18) for connecting the mode switch (4) with the impact mechanism (10), the impact mechanism switching means (18) having a swiveling mechanism switchable by the mode switch (4) between an active position in which the impact mechanism (10) is switched on, and a passive position in which the impact mechanism is switched off;
- wherein the swiveling mechanism has a switch-side swiveling member (24) which is held so as to be swivelable at a first rotary bearing (D1), is movement-coupled with the mode switch (4), and is actuated by actuating means, depending on the position in which the impact mechanism (10) is switched on or off;
- and
- wherein the actuating means comprises a swiveling member (26) on the impact mechanism side that is held at a second rotary bearing (D2) so as to be swivelable transverse to the switch-side swiveling member (24).
