Patent ID: 8499991

Claim:
A device for driving a fastening element into a substrate, comprising an energy-transfer element that can move along a setting axis between a starting position and a setting position for transferring energy to the fastening element; a guide channel for guiding the fastening element; a contact-pressing mechanism arranged displaceable relative to the guide channel in the direction of the setting axis for identifying the distance between the device and the substrate in the direction of the setting axis; a locking element that allows displacement of the contact-pressing mechanism in a released position of the locking element and prevents displacement of the contact-pressing mechanism in a locked position of the locking element; and, an unlocking element that can be actuated from the outside and holds, in an unlocked position of the unlocking element, the locking element in the released position of the locking element and allows, in a waiting position of the unlocking element, a movement of the locking element into the locked position.
