Abstract
The invention discloses a portable tool having a housing with a gearhead, having a motor shaft which can be rotationally driven by a motor and which can be coupled via an eccentric coupling drive to a tool spindle for the drive thereof, wherein the tool spindle can be driven in a rotational oscillatory manner about the longitudinal axis thereof and is configured for accommodating a tool, wherein a motion-reversal drive is provided which is configured for converting an oscillating drive movement produced by the eccentric coupling drive into an oscillating output movement which has a direction of oscillation opposed to said drive movement. The motion-reversal drive is configured as an epicyclic gearing.

A portable power tool comprising:
- a housing having a gearhead;
- a motor rotationally driving a motor shaft;
- a tool spindle comprising a tool receptacle for receiving a tool;
- an eccentric coupling drive being driven by said motor shaft, said eccentric coupling drive driving said tool spindle rotatingly oscillatingly about a longitudinal axis thereof;
- and
- a motion-reversal drive being configured for converting an oscillating drive movement generated by said eccentric coupling drive into an oscillating output movement having a direction of oscillation opposed to a direction of oscillation of said eccentric coupling drive;
- wherein said eccentric coupling drive comprises a revolving eccentric being rotatingly driven by said motor and engaging an arched surface of a swivellable driver fork driving said motion-reversal drive;
- wherein said motion-reversal drive is configured as an epicyclic gearing.
