<p>The device has a sleeve (2), which forms a rotary axis that is inserted into an opening (5) of a movable portion (1) and an opening of a fixed portion, and has a locking element (16) at an end. A pressure spring (3) is provided, which braces the movable portion and the fixed portion against each other in the locked position. The locking element and the inner contour of the fixed portion are formed, such that the pressure spring in the assembled state generates axial and tangential force components over the locking element. The force components press the movable portion against the contact surfaces of the fixed portion on one hand for determination of height and on the other hand for determination of angle direction of the movable portion and the fixed portion.</p> |
