Patent ID: 7914005

Claim:
A hand-held setting tool comprising an actuation switch ( 13 ); connection means ( 16 ) for connecting the setting tool ( 10 ) to a positioning device ( 20 ) and having a counter-coupling element ( 18 ) for the positioning device ( 20 ); a structural component ( 33 ); and a mechanical switching link ( 30 ) including at least one first switching element ( 34 ) displaceable in the structural component ( 33 ) along a longitudinal axis (A) of the setting tool ( 10 ) for connecting an actuation element provided on the positioning device ( 20 ) with the actuation switch ( 13 ); and a safety device ( 50 ) for preventing actuation of the actuation switch ( 13 ) at an orientation other than a predetermined orientation of the setting tool ( 10 ) and including at least three separate channels ( 56 ), at least three blocking members ( 55 a , 55 b , 55 c ) displaceable in the at least three separate channels ( 56 ) respectively, and a recess ( 51 ) provided on the first switching element ( 34 ) for receiving the blocking members ( 55 a , 55 b , 55 c ) and which opens toward the structural component ( 33 ), wherein the at least three channels ( 56 ) are inclined with respect to a plane (E) extending perpendicular to the longitudinal axis (A), and wherein the at least three channels ( 56 ) intersect, in some regions, an axial projection of the first switching element ( 34 ) in the form of a secant and are open toward the first switching element ( 34 ) in respective overlapping regions ( 59 ).
