The first axle body and the second axle body are mounted in a headpiece such that the housing is horizontally rotatable about an essentially vertical lengthwise axis of the first axle body and vertically pivotable about an essentially horizontal lengthwise axis of the second axle body. The headpiece has at least one friction surface for the horizontal rotational movement and further friction surfaces for the vertical pivotal movement. For braking such movements there is provided but a single resilient element such as a compression or pressure spring. | |
