Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of elongation and is not less than 9cm, shortens the flexible pen of gear type pen core point servo-actuated of a 5cm.

The implementation of the utility model purpose is, 1, the flexible pen of gear type pen core point servo-actuated, include an overcoat, handwriting 5, pen core cover, pen core 1, nib, pen hanging blind nut 9, pen hanging 8 and handwriting, refill expansion mechanism.Overcoat 7 lower ends, pen core overlaps 2 upper ends tooth bar 6,3, with pen core cover tooth bar 3 meshed gears 4 also with 6 engagements of gear bar.Handwriting 5 an outer dress overcoat gib block 13, an overcoat gib block 13 moves in an overcoat lower end gathering sill.The outer spring 14 that is equipped with of nib under the pen core 1, pen core has put handwriting lid 10.Overcoat is upper and lower the locating hole 12 that springs into for the motion shell fragment 11 on the handwriting.

Overcoat 7 lower ends, pen core overlap 2 upper ends and also can adorn thread 6,3.

Operation principle of the present utility model is: when needing to use, be pulled outwardly handwriting 5, overcoat 7 lower end tooth bars 6 (also available thread 6) driven wheel 4 rotates counterclockwise, the gear 4 that rotates counterclockwise drives pen core cover 2 by tooth bar 3 (also available thread 3) and moves downward along the handwriting inner chamber, thereby nib stretches out with the elongation of handwriting and pen core cover, and under the active force that spring 14 makes progress, make nib stretch out the location, back, the Location resilient piece 11 of handwriting upper end falls into the following locating hole 12 of an overcoat, pen is in＞the elongated condition (see figure 1) of 9cm, thereby reaches the state of writing.

Same principle, in the time of need carrying, in an overcoat 7, shorten handwriting 5, overcoat lower end tooth bar 6 (also available thread 6) driven wheel 4 clockwise rotates, the gear 4 that clockwise rotates drives pen core cover 2 along fortune association on the handwriting inner chamber by tooth bar 3 (also available thread 3), under spring 14 active forces, pen core random notes core retainer plate move up nib with the indentation of handwriting indentation penholder inner chamber, when an overcoat continues downwards, its tooth bar 6 breaks away from gear 4, and pen core is located behind the indentation penholder inner chamber under spring 14 makes progress active force and 10 restrictions of handwriting lid.At this moment, the Location resilient piece of penholder upper end falls into the last locating hole 12 of an overcoat, and the locked location of pen core is in＜the contraction state (see figure 2) of 5.5cm.

Overcoat axially directed by finishing an overcoat gib block 13 and cooperating of overcoat lower end gathering sill.

The utility model is simple in structure, and elongating, shortening only needs an action, and is very easy; Overcoat and handwriting are designed to one, do not need separate operation, are difficult for each other breaking away from, and guarantee that pen is in the integrality of using, carrying; Also can make the accessories thing uses.
