Description

From starting writing

(1) technical field:

The present invention relates to a kind of stationery, a kind of specifically from starting writing.

(2) background technology:

Thereby mainly having solved pen core, the present invention can't use wasting drawback fully.

(3) summary of the invention:

This comprises chalk, pencil, wax crayon, rubber from the employed pen core of starting writing.

Inner core (2) can move forward and backward in pen container (1), drives pen core and moves forward and backward.

Pen container (1) is provided with cannelure, and inner core (2) is provided with dop, and dop longitudinally groove moves forward and backward.

Dop (3) is scalable, and after dop (3) withdrawal, inner core (2) can take out in pen container (1).

This allows the user to load pen core from the front end of pen from starting writing, also can load pen core from the rear end of pen.

The user loads pen core if inner core (2) is taken out from the rear end of pen in pen container (1), its advantage is to take out residual pen core, and residual pen core still can continue to use behind the new pen core of packing into, thereby reaches the best utilization rate of pen core.

(4) description of drawings:

Fig. 1 is from starting writing overall diagram.(1) is pen container among the figure, and (2) are inner cores, and (3) are dops.

Fig. 2 is inner core (2) and the dop (3) after the taking-up in pen container (1).

Fig. 3 is the top plan of pen container (1).

Fig. 4 is the lateral plan of pen container (1).

(5) specific embodiment:

When using, the user loads pen core from the rear end of starting writing certainly if select, its advantage is not take out residual pen core, inner core (2) is taken out from the rear end of pen container (1), the new pen core of packing into from the rear end of pen container (1), the pen container (1) of again inner core (2) being packed into from the rear end of pen container (1) at this moment can drive inner core (2) with hand propelled dop (3) and advance, inner core (2) drives new pen core and advances, new pen core drives residual pen core and advances, and residual pen core can continue to use, thereby reaches the best utilization rate of pen core.

Claims (3)

1, a kind of from starting writing, it is characterized in that: pen container (1), inner core (2), dop (3), dop (3) is scalable.

2, according to claim 1 from starting writing, it is characterized in that: pen container (1) is provided with cannelure.

3, according to claim 1 from starting writing, it is characterized in that: inner core (2) is provided with dop (3).
