Abstract

A driving tool for driving fasteners means into workpieces comprisinga main cylinder with a piston displaceable therein and a sealing element on the lower end with a first through hole through which a piston rod connected to the piston is guided in a sealing manner,a pressing cylinder that carries on the lower end an outlet tool with a driving channel into which a lower section of a driving tappet connected to the piston rod projects through an upper opening and that has a lower opening at the bottom for discharging fasteners,a magazine for fastening means that is attached to a side opening of the driving channel in order to supply fasteners to the driving channel,a first holding device that has a first holding element connected to the piston rod and a second holding element connected to the pressing cylinder that are designed so that the pressing cylinder can be displaced into an upper pressing cylinder position by displacing the piston into an upper piston position and the outlet tool can be placed onto a workpiece by displacing the piston downwards from the upper piston position,a first stop device that has a first stop element connected to the piston rod and a second stop eleme…
