  • the invention relates to a combustion-powered setting tool for driving bolts in a substrate with the features of claim 1.
  • Such setting devices or machines are known, for example, as pin pushing devices on the market. They serve in particular the introduction of nails as bolts in concrete.

  • the driving piston comprises on the one hand a piston head, which is acted upon by the combustion gases, and the piston rod, whose end facing away from the piston head acts on the bolt.
  • the piston rod which is guided in a piston rod guide, has a smaller diameter than the piston head, which is guided in a piston head guide. However, this is not absolutely necessary.

It is limited by the side facing away from the bolt of the piston head, hereinafter referred to as the back, and is thus dependent on the position of the driving piston in the piston head guide. After driving a bolt, the driving piston is returned within the piston guide, wherein the position of the driving piston can be adjusted before the next driving.
  • the object of the invention is therefore to provide a setting tool, in which the power regulation can be done just before the attachment to the ground, without additional movements are necessary, and at the same time has a simple, robust construction.
  • the invention proposes that the driving piston are guided in a piston head guide and a piston rod guide and that these two guides are displaceable to each other.
