The spindle is provided with a bi-stable mechanical holding mechanism (3) which, when activated (by pressure on the tube (13) or on a trigger element/pushbutton), is alternately locked in the expanded and contracted position. It is hereby achieved that tubes (13) can be mounted and removed easily and quickly without the use of tools.</p> |
