Abstract
The invention relates to a drive-in device, comprising a handheld housing (20) having an energy transfer element accommodated therein for transferring energy to a fastening element, a driving apparatus for transporting the energy transfer element, at least one electric motor (480), and a gearing (401, 406) having an output shaft, wherein the driving apparatus can be driven by means of the electric motor (480) via the output shaft (404) of the gearing (401, 406), wherein at least one first gear ratio and one second gear ratio different from the first gear ratio, between a rotational speed of the motor (480) and a rotational speed of the output shaft (404), can be set by means of the gearing (401, 406).
Claims20
A fastener driving device, comprising a hand held housing with an energy transmission element accommodated therein for transmission of energy to a fastener;
- a drive device for transport of the energy transmission element;
- at least one electrical motor;
- and a gear mechanism with an output shaft, wherein the driving device is driven by the electrical motor via the output shaft of the gear mechanism;
- and at least one first gear ratio and one second gear ratio, wherein the first gear ration is different than the second gear ratio, and the first gear ration and the second gear ration can be established between a rotary speed of the motor and a rotary speed of the output shaft by the gear mechanism.
