ABSTRACT:
An axially removable cylindrical holding shaft or cap for placement over and for unscrewing or removing the tip of a writing or drawing instrument, the holding shaft or a cap having a receiving bore for the instrument tip, and being comprised of at least one approximately axially extending lever which can be tilted about an axis extending approximately tangentially to the cylinder wall. The lever has an arm on each side of the axis. One of the arms forms part off the wall and has a detent at its end, the detent projecting into the receiving bore for engaging a groove or an undercut of the tip when the tip is inserted into the receiving bore, fixing the tip in the axial direction. The structure makes it possible to clean the adjustment system of the tip, avoiding the danger of getting it dirty, and without touching the tip while reinserting it into the housing.
