An indirect firing fastening tool with an anti-firing trigger support. The tool comprises, in one case, an axially movable equipment with a tip guide projecting from the case to drive a fastening member into a support material, a reception housing for a fastener charger and anti-firing safety means to prevent the recoil of the tip guide. Advantageously, an anti-firing trigger support is mounted on said reception housing to convert the tool into a mono-firing tool, the trigger being arranged to cooperate with the anti-firing safety means so as to remove them and authorize firing.

The pole comprises a securing end, with device securing means and the device actuating means, a gripping end to be gripped by an operator and telecontrolling means for telecontrolling the actuating means. The actuating means are arranged in the device securing means and are directly controlled by the securing end of the pole and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The device actuating means comprise safety means arranged to avoid by gravity the control of the actuating means by the securing end of the pole when the spatial position of the pole is inappropriate. The invention also relates to an anchoring device provided with the same safety means.

The tool is to be used for driving fastening members into a supporting material. It comprises a cylinder (), with a piston (), a combustion chamber (), a cylinder head () bearing a fuel igniting means () in the chamber (), a pin guide (), for receiving a fastening member and the piston () shaft () and a cage (). Return means are provided for opening the chamber (), driving the pin guide () forwardly, opening and closing abutment means for the chamber (). There are provided:

The tool comprises an engine for propelling a piston including a shaft for driving a fastening member into a supporting material and through a pin guide, with means for adjusting the depth of drive of the piston shaft outside the pin guide at the end of the propulsion and at the stop of the piston in abutment against stop means. The pin guide is mounted free in translation and the depth of drive adjusting means comprise an adjustment knurl with a knurl shaft arranged so as to be in abutment against the pin guide and to push the pin guide forwards under the rotation action of the knurl.

The gas-operated fixing device comprises an internal combustion engine for driving fasteners, arranged in a case () fitted in a handle () and fixed to it at the rear (--). The front () of the case () is fitted floating in the handle () so as to be able to slide in it along the drive axis () of the fasteners. To be more specific, the case () and the handle of the device (-) are fixed to each other by tenon () and slot () assemblies.
