Patent ID: 7128252

Claim:
Setting device for driving fastening elements into a receiving material comprises a housing ( 11 ) containing an axially elongated piston guide ( 13 ) having a leading end and a trailing end and forming an axially extending hollow space ( 14 ) between the leading and trailing end, an axially extending setting piston ( 15 ) is displaceably mounted in said hollow space, a bolt guide ( 16 ) connected to the leading end of said piston guide ( 13 ) at an interface ( 17 ), a piston restoring device ( 20 ) containing an adjusting member ( 21 ) engageable in said piston guide ( 13 ) in a work position ( 23 ) and displaceable from said piston guide ( 12 ) transversely of the axial direction of said piston guide into a release position ( 24 ), a securing element ( 30 ) supported on the leading end of said piston guide ( 13 ), said adjusting member ( 21 ) being held in the work position ( 23 ) in a first position ( 33 ) of said securing element ( 30 ) and said adjusting member ( 21 ) being released for displacement linearly into said release position ( 24 ) in a second position ( 34 ) of said securing element ( 30 ) is displaced axially between the first position ( 33 ) and the second position 34 with said securing element ( 30 ) held in its first position ( 33 ) by said bolt guide ( 16 ) in an assembled position thereof and said securing element ( 30 ) can be displaced into the second position ( 34 ) by displacing means when said bolt guide ( 16 ) is displaced into the second position ( 34 ) by displacing means when said bolt guide ( 16 ) is displaced axially out of the leading end of said piston guide into a disassembled position.
