Abstract

In accordance with an aspect of the application, a device for the driving in of an affixing element into a substrate has an energy transfer element for the transfer of energy to the affixing element. Preferably, the energy transfer element can be moved between a starting position and a placement position, wherein the energy transfer element is located in the starting position before a driving-in process and in the placement position, after the driving-in process.
In accordance with another aspect of the application, the device comprises a mechanical energy storage unit for the storage of mechanical energy. The energy transfer element is then preferably suited for the transfer of energy from the mechanical energy storage unit to the affixing element.
