1. An apparatus for driving a fastening element into a base material, comprising a power unit and a driving element which is driven by the power unit in a driving direction from a starting position into a setting position to drive a fastening element into the base material, furthermore comprising a braking element comprising a holder with a contact surface which defines the setting position of the driving element and against which the driving element lies, the braking element further comprising a damping element and an impact element, wherein at the end of driving the fastening element into the base material, the driving element strikes against the impact element and is braked in a manner damped by the damping element, the apparatus furthermore comprising a pressing element which has an end surface which can be pressed in the driving direction onto the base material, wherein, in the driving direction, the end surface and the contact surface are at a distance from each other which defines a driving depth of the fastening element into the base material, furthermore comprising an adjustment device with which the distance between the end surface and the contact surface can be adjusted, wherein the adjustment device comprises an adjusting element comprising a threaded sleeve having a first external thread and a second external thread, the adjustment element being screwed on to the braking element by a first threaded connection, and by a second threaded connection to the pressing element, wherein the first threaded connection has a right-handed thread and the second threaded connection has a left-handed thread, such that, owing to the first threaded connection having the right-handed thread, rotation of the adjusting element offsets the adjusting element relative to the braking element and, owing to the second threaded connection having the left-handed thread, rotation of the adjusting element offsets the adjusting element relative to the pressing element, and therefore rotation of the adjusting element offsets the pressing element relative to the braking element.
