Abstract

The utility model relates to an autopen the structure of which comprises a pen barrel, an outer barrel provided with a chuck and an inner core which can be taken out from the pen barrel. The autopen has the advantage of achieving the optimal usage rate of a pen core.

Description

From starting writing

(1) technical field:

The utility model relates to a kind of stationery, and is a kind of specifically from starting writing.

(2) background technology:

Thereby mainly having solved pen core, the utility model 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.

Pen container (1) is provided with cannelure, urceolus (4) is enclosed within pen container (1) outside, urceolus (4) is provided with dop (3), the cannelure of the corresponding pen container of dop (3) (1), dop (3) longitudinally groove moves, and inner core (2) is contained in pen container (1) the inside, the direction of the corresponding dop of the groove on the inner core (2) (3), a branch of like this, urceolus (4) moves forward and backward and can drive inner core (2) and move forward and backward in pen container (1), and inner core (2) can drive pen core and move forward and backward.

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

This allows the user from starting writing, can load pen core from the front end of pen, 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 (4) are urceolus.

Fig. 2 is the lateral plan of pen container (1).

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

Fig. 4 is the outside drawing of inner core (2).

Fig. 5 is the outside drawing of urceolus (4), and (3) are dops among the figure.

(5) specific embodiment:

When using, the user loads pen core from the rear end of starting writing certainly if select, can 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), make dop (3) on the urceolus (4) snap in groove on the inner core (2), at this moment can drive inner core (2) with hand propelled urceolus (4) advances, inner core (2) drives new pen core and advances, new pen core drives residual pen core and advances, residual pen core can continue to use, thereby reaches the best utilization rate of pen core.

Claims (1)

1. start writing certainly for one kind, it is characterized in that: parts have pen container (1), inner core (2), dop (3), urceolus (4), pen container (1) is provided with cannelure, inner core (2) is provided with groove, urceolus (4) is provided with dop (3), dop (3) is scalable, and pen container (1) is in inner core (2) outside, and urceolus (4) is in pen container (1) outside.
