According to one aspect of the application, a device for driving a fastening element into a substrate has an energy-transfer element for transferring energy to the fastening element. The energy-transfer element can move preferably between a starting position and a setting position, wherein the energy-transfer element is located, before a driving-in procedure, in the starting position and, after the driving-in procedure, in the setting position. According to another aspect of the application, the device comprises a mechanical-energy storage device for storing mechanical energy. The energy-transfer element is then suitable preferably for transferring energy from the mechanical-energy storage device to the fastening element.

Driving device

A hand-held drive-in tool for driving in fastening elements includes a drive-in ram (), a drive () for driving the drive-in ram () and having a driving spring member () for displacing the drive-in ram (), a device () for preloading the driving spring member (), a locking device () having a locking position () in which the locking device () retains the driving spring member () in its preloaded position and a release position () into which the locking device () is displaced upon actuation of an actuation switch () of the drive-in tool (), and a mechanical blocking device () operating independently of the actuation switch () and having an active position () in which the blocking device () retains the locking device () in its locking position (), and a passive position () in which the locking device () can be displaced in its release position ().

Hand-held drive-in tool

A hand-held drive-in tool () for fastening elements () includes a driving unit () for a drive-in ram () which is displaceably mounted in a guide (), and has at least one driving element for the drive-in ram () formed by an elastomeric band () and tensioned by a tensioning device ().

A hand-operated drive-in power tool for fastening elements is disclosed. The tool has a drive arrangement for a drive-in ram displaceably arranged in a guide, which has at least one drive element for the drive-in ram made at least partially of an elastomer that is tensible via a tensioning device. To improve the drive-in power tool, a heating device for the at least one elastomer drive element is provided.

Hand-operated drive-in power tool

A hand-held fastener driver for fastening elements, having a driving tappet that is movably mounted in a tappet guide and that can be driven using at least one drive spring element is disclosed, having a tensioner for the drive spring element, and having a locking mechanism. In a locked position of the locking mechanism, the drive spring element can be locked in its tensioned position, whereby the tensioner has a tensioning element that is provided with a profile, and said tensioning element can be axially moved along a longitudinal axis of motion using a rotatable counter-element that is engaged with the profile and that can be driven by a motor.

Hand-held fastener driver
