An apparatus for driving a fastening element into a base material, comprising a power unit and a driving element which is provided 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; a braking element with a contact surface which defines the setting position of the driving element and against which the driving element lies in the setting position; 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; and, an adjustment device with which the distance between the end surface and the contact surface can be adjusted.

Driving-in device

The invention relates to a pull-out tester () for a setting tool used for setting a setting bolt (), comprising a retaining part () for holding the setting bolt (), an elastic element (), at least one means () for transmitting a pull-out force acting on the setting bolt () onto the elastic element () such that if a pull-out testing force acting on the setting bolt () is exceeded, the connection between the setting bolt () and the pull-out tester () can be detached due to a deformation of the elastic element (). The problem addressed by the invention is that of being able to provide a substantially constant pull-out testing force, even in different temperatures and with a different pull-out speed of the pull-out tester (). The problem is solved in that the force transmitted to the elastic element () in order to deform the elastic element () substantially causes an elastic deformation of the elastic element () and the connection between the setting bolt () and the pull-out tester () can be detached due to the substantially elastic deformation of the elastic element ().
