<p>The machine has a tine support arm (3) with two telescopic support arm parts (3a, 3b), which are fixed together by a fixing device (5). The fixing device includes a locking element i.e. ball, which is radially and movably supported at one of the arm parts and locked in a locking contour at the other arm part. A control element (8) is axially and/or rotatably movably supported at the former arm part, and allows radial positioning of the locking element according to axial or rotatary positioning of the locking element. The control element is formed as a covering for the locking element.</p> |
