Positioning device with actuating switching means for a hand-held setting tool

A positioning device for a hand-held setting tool (10) having an actuation switch (13) for actuating the setting tool (10), the positioning device comprising a rod-shaped holder (21) defining a longitudinal axis (A);

• connection means (22) for the setting tool (10) arranged at an end of the holder (21);
• and actuating switching means including an actuation element (24), a switching link (30) for connecting an actuation element (24) to the actuation switch (13) of the setting tool (10) and having a switching member axially displaceable relative to a stationary, with respect to the holder, structural component, and a safety device (50) for preventing actuation of the actuation switch (13) at a predetermined orientation of the setting tool (10) and including a displaceable blocking element (55), a first annular recess (51) for receiving the blocking element and extending radially circumferentially about the structural component and a second annular recess (52) extending radially circumferentially about the switching member and located, at least in an initial position of the positioning device (20) radially opposite the first annular recess (51), the first annular recess (51) and the second annular recess (52) being open toward the switching member and the structural component, respectively, the blocking element (55) being completely positionable in one of the first and second annular recesses (51) in an operational position of the actuation switching means, wherein the structural component is formed by a portion (46) of a coupling element (28), wherein the switching member is a first switching member (33) of the switching link (30) which is sleeve-shaped and is guided over a radial outer surface of the portion (46) of the coupling element (28).
