摘要

The locking unit for working heads, with locking means (17) fastened on a first component (8) for acting on a second component (3) which is movable relative to the first, has the locking means constructed for loading the second component basically in a compensated manner in the absence of external loads. The locking means have a ring-form element which is fastened on the second component and which extends around the axis (C). The ring-form element has a basic body with an end section from which projects a side element.
