The disclosure is based on a sensor device, in particular a hand-held power-tool sensor device, for identifying an uncontrolled occurrence of jamming in the case of a hand-held power tool, having at least one sensor unit, which is provided to sense at least one motion characteristic value of the hand-held power tool, and having a protective unit, which is provided to control the hand-held power tool in dependence on at least one triggering threshold value and the at least one motion characteristic value. It is proposed that the protective unit be provided to set the at least one triggering threshold value in a variable manner and/or to define at least one further triggering threshold value.

Sensor device, in particular hand-held power-tool sensor device

Hammer drill

The invention is based on a hammer drill and/or chisel hammer, having an impact mechanism unit, an impact mechanism housing and at least one damping unit. The invention proposes that the damping unit is arranged on the impact mechanism housing along a main extension direction of the impact mechanism unit.

Hammer drill and/or chisel hammer

The invention relates to a hand-held power tool, especially a rotary hammer and/or chisel hammer. The hand-held power tool is provided with a vibration dampening unit having a first absorber mass unit with a first vibration dampening direction and at least one second absorber mass unit with a second vibration dampening direction. The hand-held power tool in particular has the first vibration dampening direction of the first absorber mass unit disposed as substantially parallel to the second vibration dampening direction of the second absorber mass unit.

Hand-held power tool

The invention relates to a wobble drive of a hand-held machine tool, particularly a drilling or chipping hammer, having a drive shaft, a wobble bearing disposed on the drive shaft, and a wobble plate supported on the wobble bearing. At least two wobble fingers having wobble finger axes being provided on the wobble plate. The invention provides that the axes of the wobble fingers form an angle different from 180&#xb0;.
