Abstract:
1. A device for driving a fastening element into a substrate, comprising a mechanical-energy storage device for storing mechanical energy, the mechanical-energy storage device comprising a spring; an energy-transfer element that can move between a starting position and a setting position for transferring energy from the mechanical-energy storage device to the fastening element; an energy-transfer mechanism for transferring energy from an energy source to the mechanical-energy storage device, the energy-transfer mechanism comprising a spindle and a nut; and, a force-transfer mechanism for transferring a force from the energy-transfer mechanism to the mechanical-energy storage device, the force-transfer mechanism comprising a belt, wherein the force-transfer mechanism and one of the spindle and the nut are acted upon mutually with a force, while the energy-transfer element transfers energy to the fastening element.
