Patent ID: 8807413

Claim:
A device for driving a fastening element into a substrate, comprising an energy-transfer element that can move between a starting position and a setting position for transferring energy to the fastening element; a drive mechanism for transporting the energy-transfer element from the starting position into the setting position and back, wherein the drive mechanism comprises (a) a movement converter for converting a rotational movement into a linear movement with a rotational drive and a linear output, (b) a retaining mechanism suitable for stopping motor output rotation, and (c) a motor-damping element that is suitable for absorbing movement energy of a motor with respect to the movement converter, wherein the motor-damping element is arranged on the retaining mechanism; and, the motor, with a motor output and a torque-transfer mechanism for transferring a torque from the motor output to the rotational drive, wherein the torque-transfer mechanism has a motor-side rotating element with a first rotational axis and a movement converter-side rotating element with a second rotational axis offset parallel with respect to the first rotational axis, wherein a rotation of the motor-side rotating element about the first axis directly causes a rotation of the movement converter-side rotating element, and wherein the motor-side rotating element is arranged immovable relative to the motor output and is movable along the first rotational axis relative to the movement converter-side rotating element.
