Abstract

An automatic pencil with a pencil core capable of being replaced conveniently is characterized in that a core device (1) is mounted at the top end of the pencil tube of a common automatic pencil; a fixed disc (2) is arranged at the bottom part of the core device (1); a core hole (3) is formed on the fixed disc (2); a rotating shaft (4) is fixedly connected to the upper end of the fixed disc (2); a pencil core bin (5) is sleeved on the rotating shaft (4) and can rotate around the rotating shaft (4); a plurality of core storage tubes (6) are arranged along the circular inner wall of the pencil core bin (5); an axis distance between the core storage tubes (6) and the central shaft of the rotating shaft (4) is identical with that between the core hole (3) and the central shaft of the rotating shaft (4). The utility model quickly selects one required pencil core at one time, effectively protects the pencil core, and has the advantages of convenience, practical use, simple operation and low cost.

Description

Conveniently change the propelling pencil of core

Technical field

The utility model relates to stationery, is a kind of propelling pencil that conveniently changes core specifically.

Background technology

Pencil plays a significantly greater role in daily study and work, and a kind of propelling pencil that can automatic propelling is arranged in the market, brings great convenience to the user.Yet the pen core of this propelling pencil all stores in the shaft of a writing brush, is easy to be stuck in the process of knockout, thereby pen core is broken down.

Summary of the invention

What the purpose of this utility model provided a kind of optional core conveniently changes the core propelling pencil.

The described propelling pencil that conveniently changes core is characterized in that: on the shaft of a writing brush top of common propelling pencil a knockout is housed; The bottom of described knockout is a fixed disk, fixed disk has the knockout hole, the fixed disk fixedly connected rotating shaft in upper end, and the pen core storehouse is enclosed within the rotating shaft, circular inner wall along the pen core storehouse is provided with a plurality of core storage tubes, and core storage tube is identical to the distance of shaft centers of rotating shaft axis with the knockout hole to the distance of shaft centers of rotating shaft axis.

The utility model can be selected the pen core of required usefulness fast, once goes out one, can effectively protect pen core; Convenient and practical, simple to operate, cost is low.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1-knockout, 2-fixed disk, 3-knockout hole, 4-rotating shaft, 5-pen core storehouse, 6-core storage tube.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further specified: the propelling pencil that conveniently changes core as shown in Figure 1 is characterized in that: on the shaft of a writing brush top of common propelling pencil a knockout 1 is housed; The bottom of described knockout 1 is a fixed disk 2, fixed disk 2 has knockout hole 3, the fixedly connected rotating shaft 4 in fixed disk 2 upper ends, pen core storehouse 5 is enclosed within the rotating shaft 4 and can rotates around it, circular inner wall along pen core storehouse 5 is provided with a plurality of core storage tubes 6, and core storage tube 6 is identical to the distance of shaft centers of rotating shaft 4 axis with knockout hole 3 to the distance of shaft centers of rotating shaft 4 axis.

Principle can easily be found out from Fig. 1:

In advance pen core being put into core storage tube 6 successively stores standby;

After the pen core that is using uses up, rotate pen core storehouse 5 with hand, when some core storage tubes 6 in pen core storehouse 5 align with the knockout hole 3 of lower end fixed disk 2, pen core in the core storage tube 6 will weigh down in the shaft of a writing brush automatically, so just can be with new pen core, one time one, just pen core is stuck.

We can also be placed on diameter difference, pen core that color is different in the different core storage tube 6, just can selectively select pen core according to different needing during use and use.

Claims

1. a propelling pencil that conveniently changes core is characterized in that: on the shaft of a writing brush top of common propelling pencil a knockout (1) is housed; The bottom of described knockout (1) is a fixed disk (2), fixed disk (2) has knockout hole (3), fixed disk (2) upper end fixedly connected rotating shaft (4), pen core storehouse (5) is enclosed within the rotating shaft (4), circular inner wall along pen core storehouse (5) is provided with a plurality of core storage tubes (6), and core storage tube (6) is identical to the distance of shaft centers of rotating shaft (4) axis with knockout hole (3) to the distance of shaft centers of rotating shaft (4) axis.
