<p>The device (1) has a support and a rotating part (3), which is arranged at the support by using a fastening unit (5). The fastening unit and the rotating part have a common, stationary axis and form a bayonet connection (6), which is arranged in such a manner that the rotating part is rotatable at both sides around the axis. The fastening unit is designed as a single piece, and has a rotationally symmetric base body (8) and a rotation-asymmetrical cross section extension (9). The rotating part forms a rotation-asymmetrical passage for the fastening unit.</p> |
