Die Haltehülse i besitzt einen durchgehenden Längsschlitz 2, damit sich diese Hülse dem Durchmesser jedes Bleistiftes 3 anpassen kann. Außerdem ist diese vorn kegelig zulaufende Hülse mit einer Reihe von kurzen Schlitzen 4. versehen, die diesem Ende der Hülse eine besonders gute Zusammendrückbarkeit geben, wenn die Schutzhülse 5, die ebenfalls vorn kegelig zuläuft (Abb.3), auf die Haltehülse i aufgeschoben wird. Der Ring 6 dient, wie bekannt, dazu, wenn er rückwärts auf die Warze 7 der Hülse r geschoben wird, diese Hülse fest an den Bleistift 3 zu drücken.

Um die Schutzhülse in der vorgeschobenen Stellung derart festzuhalten, daß die Mine gegen Abbrechen geschützt wird, kann noch eine dritte Warze an entsprechender Stelle an der Hülse i vorgesehen sein.The holding sleeve i has a continuous longitudinal slot 2 so this sleeve can adapt to the diameter of each pencil 3. Also is this sleeve, which is tapered at the front, is provided with a series of short slots 4., which give this end of the sleeve a particularly good compressibility when the Protective sleeve 5, which also tapers conically at the front (Fig. 3), onto holding sleeve i is postponed. The ring 6 is used, as is known, when he backwards on the If the protrusion 7 of the sleeve r is pushed, this sleeve is pressed firmly against the pencil 3. The second wart 8 gives the opportunity to easily remove the protective sleeve 5 that has been pushed back to be held in such a way that the front end i of the sleeve is firmly compressed and the Mine 9 is held even if it is broken off.
