Abstract
A hand-held tool gear mechanism unit includes a drive gearwheel, an output gearwheel, and a connecting unit. The output gearwheel has a rotational axis spaced apart radially from a rotational axis of the drive gearwheel. The connecting unit is configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio. The connecting unit is configured to couple the drive gearwheel and the output gearwheel such that they can be moved relative to one another about a pivot axis.

A hand-held tool gear mechanism unit, comprising:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- and
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio,
- wherein the connecting unit is configured to couple the drive gearwheel and the output gearwheel such that the drive gearwheel and the output gearwheel can move relative to one another about a pivot axis.
A hand-held tool, comprising:
- a hand-held tool gear mechanism unit, including:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- and
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio,
- wherein the connecting unit is configured to couple the drive gearwheel and the output gearwheel such that the drive gearwheel and the output gearwheel can move relative to one another about a pivot axis.
A system comprising:
- a hand-held tool, including:
- a hand-held tool gear mechanism unit, including:
- a drive gearwheel;
- an output gearwheel having a rotational axis spaced apart radially from a rotational axis of the drive gearwheel;
- a connecting unit configured to transmit a rotational movement from the drive gearwheel to the output gearwheel substantially without a step-up transmission ratio;
- and
- a coupling apparatus configured to produce a connection to the hand-held tool,
- wherein the connecting unit is configured to couple the drive gearwheel and the output gearwheel such that the drive gearwheel and the output gearwheel can move relative to one another about a pivot axis, and
- wherein the coupling apparatus is further configured so that the connection is terminable in response to an operator action.
