A support arm (5) movably fixed to the column so as to swivel on a horizontal swivel axis is raised and lowered by a spindle (7) and supports a fixed or swiveling support part on its free end (6). The end fitting into the column has cogging engaging with counter-cogging on a distributing regulator (10) and moves the distributing regulator parallel with the lengthwise direction of the column, The counter-cogging is in the form of holes.
