Socket wrench extension device

摘要

The device has a polygonal insert part (2) with an axially held pressure transmission element (8) with one journal or key-shaped end (14) for its actuation. The other end forms part of a mechanism to translate an axial movement acting in direction of the insert part, into an outward movement of a locking part (4). The other end of the pressure transmission element has a slope (10) engaging on the radially guided locking part.
