Abstract:
1. A device for driving a fastening element into a substrate, comprising a mechanical-energy storage device for storing mechanical energy, and an energy-transfer mechanism for transferring energy from an energy source to the mechanical-energy storage device, wherein the energy-transfer mechanism comprises a motor with a motor output that is connected in an uninterruptible and torque-coupled way to a rotational drive, a movement converter for converting a rotational movement into a linear movement with the rotational drive, and a linear output, a torque-transfer mechanism for transferring a torque from the motor output to the rotational drive and a force-transfer mechanism for transferring a force from the linear output to the energy storage device, and a rotating element that can rotate about a rotational axis and a retaining mechanism that faces the rotating element and exerts a holding force on the rotating element, in order to hold the rotating element against rotation.
