- the lead holding part 17 is caused by the rotationally fixed connection with the guide member 15 in a rectified rotational movement.
- the lead holding part 17 is now in an axial movement due to the engagement of the female thread formed on the receiving part 2 with the male thread formed on the minting-part-side counter guide sections 18, ie. H. depending on the direction of rotation of the guide part 15 or handling part 23 in a feed movement (see arrow P2) in the direction of the cap part side molding device 6 or in a reverse thrust movement in a direction opposite thereto, displaceable or offset.

- the threaded part 12 or the receiving part 2 does not necessarily have to be formed completely over its axial length with an internal thread. However, this may be accompanied by an axial extension of the threaded portion 12 and the receiving part 2 and thus a less compact structure of the pin 1 under certain circumstances.

- the male thread part 31 is provided with a radially widened area in the region of its free end facing the receiving part-side base.
- coupling elements (not designated) are formed, which cause a rotationally fixed coupling between the external thread part 31 and the receiving part 2 in cooperation with corresponding thereto receiving part side negative feedback elements (not labeled).
- the externally threaded part-side coupling elements are formed here as form-locking elements in the form of radially outwardly directed projections
- the receiving part-side negative feedback elements are formed as corresponding GegenformQuery institute in the form of inner diameter side recesses of the receiving part 2.
- a holding element 35 for holding the externally threaded part 31 in the receiving part 3 in an axially fixed position is arranged.
- the corresponding holding element 35 is generally a component having a specific adhesive and / or friction value relative to the receiving part 2, which component surrounds the outer threaded part 31 on the outer peripheral side.
- the support member 35 is an O-ring of a comparatively non-slip or soft material, such as an elastomer or silicone material.
- the external thread part 31 is on the outer peripheral side with a receiving groove (not designated) for receiving the support member 35 is provided.
- the threaded member member 29 is located within the receiving member 2 between an engagement position (see Fig. 18) in which the threaded element part side threaded member 30 engages the external thread side male thread, and a disengaged position (see Fig. 17) in which the threaded member member side threaded member 30 is not in engages the outer thread part-side external thread, slidably mounted movable.
- the movement of the threaded element part 29 within the receiving part 2 takes place, as indicated by the double arrow shown in FIGS. 17, 18, relative to the male threaded part 31.
- the receiving part 2 comprises a plurality of inner diameter ranges 2a, 2b having different inner diameters.
- a first inner diameter portion 2a has a smaller inner diameter compared to the second inner diameter portion 2b (see Fig. 17, 18).
- the transition region 36 between the axially communicating inner diameter regions 2a, 2b is formed like a ramp.
- a guide element 37 (directed radially or outwardly with respect to the symmetry or central axis of the threaded element part 29) is formed on the threaded element part 29, between the first outer diameter region 29a and the second outer diameter region 29c.
- the thread element part-side guide element 37 is a projection directed radially outwards, in particular nose-like.
- the threaded element part 29 is moved into the engagement position when it is moved into the first inner diameter region 2 a of the receiving part 2 at least in the area of the threaded element 30.
- the threaded element part 29 can be designed with elastic-resilient properties at least in the area of the threaded element part-side threaded element 30, generally at least in the outer diameter region 29a, so that it easily differs from the comparatively larger inner diameter region 2b of the receiving part 2 to the smaller inner diameter region 2a of FIG Receiving part 2 is slidably movable.
- the threaded member portion 29 is then moved into the smaller inner diameter portion 2a of the receiving portion 2 and thus into the engaged position when the cap member 5 is attached to the receiving portion 2 (see Fig. 18).
- the placement of the cap member 5 on the receiving part 2 respectively attached to the receiving part 2 cap part 5 therefore conditioned an axial movement of the threaded member 29 in the engaged position respectively a support of the moving in the engaged position threaded element part 29 in the engaged position.

- a user of the pin 1 engages the cap member 5 by hand and rotates it relative to the receiving part 2.
- the axis of rotation corresponds to the axis of symmetry of the pin 1 and the axis of symmetry of the hollow cylindrical components of the pin first
- the threaded element part 29 is caused by the rotationally fixed coupling with the cap part 5 in a rectified rotational movement.
- the externally threaded part 31 together with rotationally fixed with this coupled mine 4 is now due to the engagement of the threaded element in the engaged position member 30 with the outer thread part male thread in an axial movement, ie depending on the direction of rotation of the cap member 5 in a feed movement in the direction of the cap part side Anform worn 6 or in a return movement in an opposite thereto Direction, offset. Since the external thread part 31 is rotatably coupled to the receiving part 2, the external thread part 31 does not rotate in this case.
- the cap part 5 can comprise at least one viewing window for viewing into the interior space defined by the cap part 5 and serving as a reservoir.
- a viewing window can be recognized, for example, to what extent a corresponding cap part side defined interior during a Anform- respectively Spitzvorgangs fills with Abtragsmaterial the mine 4 or is filled after completion of Anform- respectively Spitzvorgangs the mine 4.
- Via a viewing window a user can also observe the molding process of the refill 4 and thus recognize when a desired or optimum sharpening result of the refill 4 has been reached.
- a corresponding viewing window can be replaced by one of a transparent element, for. B. from a transparent plastic, closed opening of the cap part 5 may be formed.
- the method is characterized in that a feed movement of the refill 4 to a defined at a given feed movement of the mine 4 defined Abtragsvolumen an Anform recognized 6 is adjusted or due to a slip movement within the lead advancing device to the defined Abtragsvolumen the Anform recognized 6 adapts, so that a at the given defined feed movement of the mine 4 given feed volume is not greater than that on the Anform overlooked 6 at the given defined feed movement of the mine 4 abtragbare or deformable volume in the area of the lead tip.
