  • the pawl sensor only engages minimally in the guide tube on and allows a further displacement of the pressure sleeve to the rear end of the setting tool when the pressure sleeve is pressurized from the front, so that ignition of the setting tool is now possible.
  • the pawl can be between its locking edge and its sensor at an angle to the guide tube have running adjusting edge over which the pressure sleeve during movement on the pawl to the sensor swings out of the guide tube.
  • the ignition of the Setting tool enables, it raises the pawl and thus the Sensor completely out of the guide tube, so that the following Ignition process the piston rod driven thereby for acceleration of the fastening element no longer touch the sensor can do what serves to protect the sensor and the piston rod.
  • the pawl is preferably in the direction of spring force biased to the guide tube so that after the fastener has been driven out out of the guide tube and after withdrawal of the piston rod is pushed back into the guide tube.
  • FIG. 1 A side view of the setting tool according to the invention is shown in FIG. 1. It is provided with the reference number 1 and has a housing 2 protrude from the front of a guide tube 3 and a pressure sleeve 4.
  • the pressure sleeve 4 is slidingly concentric on the guide tube 3 stored and displaceable against spring pressure inside the housing 2, when the setting tool 1 is pressed with the pressure sleeve 4 against an object is into which the fastener is to be driven. If the pressure sleeve 4 reaches a rear end position, a lock becomes of the setting tool and a driving process of the fastener can begin by pressing a trigger 5 or trigger becomes.
  • Gas mixture for example an air / fuel gas mixture using a electrical igniter are fired to drive a piston plate, which is connected to a piston rod, which is in the guide tube 3 is driven in to the fastener lying in it to slide out of the guide tube 3.
  • Fasteners are connected in the form of element strips or in the form of a belt within a magazine 6, which is from a front portion of the Setting tool 1 on the one hand and by a handle 7 of the setting tool 1 on the other hand will be carried.
  • FIG. 2 shows the more precise structure of the Setting tool 1 in its front part.
  • an inner channel 8 of the guide tube 3 is aligned with one Piston rod 9 which can be driven into the inner channel 8.
  • the piston rod 9 stands at its rear end with a piston plate in Connection, which in turn connection with a not shown Combustion chamber for receiving an air / fuel gas mixture.
  • Air / fuel gas mixture ignited by means of an electrical ignition device are so that the piston rod 9 then shot into the inner channel 8 becomes. It takes a positioned in the inner channel 8 Fastening element 10, which thereby pushed out of the guide tube 3 becomes.
  • the magazine 6 there are many fastening elements connected to one another in the form of a belt 10. These are, for example, nails in your Wear a plastic collar 11 in the head area. About these The plastic fasteners 10 are connected to one another.
  • a pressure device preloaded by spring force 12 which is located in the magazine 6, the belt of fasteners 10 biased towards the guide tube 3, so that always that most forward fastener 10 by a Cutout 13 in the wall of the guide tube 3 into the inner channel 8 is pushed in.
  • this cutout 13 is a front head part 14 of the magazine 6 inserted appropriately, through which the fasteners 10 get into the inner channel 8.
  • a stop is provided which, when the pressure device 12 has been driven against the stop, the feed spring force for the pressure device 12.
  • Figure 2 also shows that the cutout 13 opposite Another cutout 15 is present in the wall of the guide tube 3.
