Abstract

The utility model discloses a propelling pencil, which comprises a rod-shaped pencil holder (1), a conical pencil head (2) and a pencil core (3), wherein the conical pencil head (2) is connected with the pencil holder through screw threads, the pencil core (3) is in a flat bar shape, and the shape of a pencil core hole arranged at the front end of the pencil head (2) is the same as that of the cross section of the pencil core (3). The propelling pencil of the utility model designs the pencil core into the flat bar shape, and can be directly used for filling and coating machine readable cards without the phenomenon of bull pencil core, and a standby pencil core is only needed to be replaced when the pencil core is broken. The propelling pencil of the utility model has the advantages of simple structural design, convenience and practicality, and is favorable for examiners to save precious time during the examination.

Description

A kind of propelling pencil

Technical field

The utility model relates to a kind of pencil, particularly relates to a kind of propelling pencil.

Background technology

The pen core of present propelling pencil is circle, thus when examination can only come the full-filling machine-read card with traditional Pencil with 2B hardness with reference to the person, if pen core also needs to spend valuable time and sharpens a pencil with after pausing or fractureing during examination, very inconvenient.

The utility model content

Technical problem to be solved in the utility model provides a kind of propelling pencil that is exclusively used in full-filling machine-read card when taking an examination.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of propelling pencil, the taper nib, the pen core that comprise the column penholder, are threaded with penholder, its pen core are flat strip shaped, and the shape of written front end reservoir hole is identical with the shape of cross section of pen core.

A kind of propelling pencil of the utility model is designed to flat strip shaped with pen core, can directly come the full-filling machine-read card with it during examination, and pen core can not occur with phenomenon, if it fractures and also only need replace with standby pen core and get final product.A kind of propelling pencil of the utility model, structural design is simple, and is convenient and practical, helps saving valuable time with reference to the person when taking an examination.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of propelling pencil of the utility model.

Wherein, Reference numeral: 1 is penholder, and 2 is nib, and 3 is pen core.

The specific embodiment

Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.

As shown in Figure 1, a kind of propelling pencil of the utility model, the taper nib 2 that comprise column penholder 1, is threaded, pen core 3 with penholder, its pen core 3 is a flat strip shaped, the shape of written 2 front end reservoir hole is identical with the shape of cross section of pen core 3.The shape of cross section of flat strip shaped pen core 3 is a rectangle, and its length can be identical with the pen core diameter of conventional Pencil with 2B hardness, its width be length dimension 1/3rd to 1/2nd between comparatively suitable, so not only made things convenient for full-filling machine-read card but also non-frangibility.The shape of nib 2 front end reservoir hole must be identical with the shape of cross section of pen core 3, and should be slightly larger than pen core 3 sizes, guarantees that pen core 3 can get final product from wherein skidding off smoothly, and front end pen core easily too greatly then fractures when full-filling is used.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims (1)

1. propelling pencil, the taper nib (2) that comprise column penholder (1), is threaded, pen core (3) with penholder, it is characterized in that: described pen core (3) is a flat strip shaped, and the shape of nib (2) front end reservoir hole is identical with the shape of cross section of pen core (3).
