ABSTRACT:
The rotary tool has an element (10) rotatable about an axis of rotation and provided with a polygonal pin (16). A wrench socket insert (3), having a recess complementary to the polygonal pin (16), can be placed at the polygonal pin (16). The polygonal pin (16) and the tool (3) have longitudinal throughbores (18, 30). A tool element as a retaining control member (2) can be passed through the longitudinal throughbores. A transverse bore (20) is provided in the polygonal pin (16) and connected, on the one hand, to the longitudinal throughbore (18) and ends, on the other hand, at the outer surface of the polygonal pin (16). A detent ball (22) is located in the transverse bore (20) and adapted to snap into a detent passage (28) in the tool element (3). The retaining control member, as a further rotary tool element (2), can be pulled out from and rotated in the longitudinal throughbore (18); it has a cylindrical peripheral surface engaged by the detent ball (22) and thus keeps the detent ball (22) engaged with the tool element (3). At its inner end, the transverse bore (20) has a constriction (24) engaged by the detent ball (22) in its innermost position to prevent the same from falling out of the transverse bore (20) into the longitudinal throughbore (18) when the further rotary tool (2) is pulled out. In this innermost position, the detent ball (22) is forced completely out of the detent passage (28) into the transverse bore (20).
