• and
• a switching sleeve that is adjustably mounted on the hollow shaft configured to alternately switch between a first switching position and a second switching position, wherein the locking elements comprise a first subset of the locking elements and a second subset of the locking elements, wherein when the switching sleeve is placed in the first switching position, the first subset of the locking elements are configured to be in the first switching position for locking the machine tool in the receiving opening, when the switching sleeve is placed in the second switching position, the second subset of the locking elements are configured to be in the second switching position for locking the machine tool in the receiving opening while an adjustment of respective remaining locking elements is deactivated.
