directly after the explosive charge is in contact and behaves like an event when it is fired or has a barrel that contains a pressure piston which strikes the bolt head, with no indication whatsoever of the barrel length or the initial position of the piston There is a dependency on the length of the bolt to be driven in

Ψ In the first case, when driven in, the bolt hits the receiving material with extremely high kinetic energy, which can damage the unexposed surface of the material.

In the second case, the length of the bolt becomes larger when it is extended not pressed into the receiving material by the piston, but the piston exerts a hana effect on him, the not only unsatisfactory driving-in ^ but in the first case also damage to the immediate surface of the recording material can not bring "

for example, a value that is about two and a half times that the weightea of the gerltea is.

The object of the invention is to eliminate the disadvantages and shortcomings mentioned of the known bolt-shooting devices. To achieve this object, the invention provides a bolt device which has a rear part, a barrel forming a cartridge chamber, a piston that can be moved along the barrel and a lock with a firing pin uafaaat, which by acting on a trigger on the bottom of the cartridge chamber located in the cartridge chamber, whereby the inventive bolt mechanism is characterized in that a teleakopfömigea element is displaceably arranged inside aa rear part and outside the barrel, against which a, aich on aa The ring-shaped fullerene collar of the barrel, an abating spring, has the effect that a locking part is pivotably mounted, as a lock, which engages with a projection in one of two notches made at the rear end, so that a clamping lever is a rear projection with the firing pin in non-permanent Intervention stands and one before the part of which can be actuated by a projection of the trigger, the tensioning lever performing a tilting movement from the engagement position into the light engagement position, and a spring is provided which keeps the lock from the bottom of the rear part removed, so that the The front part of the cocking lever is pivoted and outside the radius of action of the front projection of the trigger until sufficient pressure is applied to overcome the force of the spring, and the telescopic element, the piston, the barrel, the lock and the clamping lever close against the cover of the rear part be moved.

A further characteristic of the invention according to let within the dee Teleekopeleaente · a guide tube for the front rod of the · piston arranged, soft tube at its front end Carrying a stoftdapfer, which is suitable for consuming the remaining energy of the piston after driving in the bolt.

The invention also provides a lock for the telescope member . in front of which the ring protrudes from the rear part and the displacement of the Teleekopeleaente * prevents if no bolt to be driven in has been inserted before it engages with the barrel koaat and the same old shifted backwards to the said To squeeze together the spring that removes the lock from the lid of the rear part. Finally, there is another Features of the erfindungegealften Bolzenechieesgerltee in the Rückatoftdlapfer between the cover of the rear part and the Bottom of the closure.

The invention is explained in more detail below using an exemplary embodiment with reference to the drawing.
