Background technology

Pencil is a kind of cultural goods, the especially child that people use always, before in the middle school, generally all carries out operation, drawing etc. with pencil, because the word that pencil writes out is carefully and neatly done, wrongly writes the back and uses erased by rubber easily, so at a lot of other fields, as art designing, drawing etc.

Propelling pencil is one of frequent pencil that uses of people, since the propelling pencil invention, people are in generally using, general propelling pencil pen core all is thinner the sort of pen core, be used as the instrument that writes, and what often use when answering multiple-choice question in the examination now is to be coated with answering card with Pencil with 2B hardness, the common way of people is to cut several Pencil with 2B hardness to bring the examination hall into, yet find that after being coated with several times pen core weares and teares, wide that is not fit to just is coated with completely whole option, need cut again this time, delayed the time of answer.And the pencil of cutting carries very inconvenient.

The utility model content

The utility model provides a kind of propelling pencil, by design mouth substituting device, the pen core with wide core point that interior dress is cut, when answer, directly utilize the operation of ejecting automatically, can constantly keep the pen core of suitable answer, save the time, and use and very convenient to carry.

The technical solution that adopts is so for achieving the above object: the propelling pencil that is provided, constitute by the cap for brush, penholder and nib,

Penholder is a hollow column, and inside is disposed with spring, connecting rod and a plurality of pen core from the cap for brush toward written direction;

The spring upper end heads on the cap for brush, and the lower end is connecting connecting rod;

A plurality of pen cores that connecting rod is provided with down join end to end, and are sequentially arranged in the penholder of hollow structure, and pen core bottom stretches out outside the nib.

Preferably, an end of above-mentioned pen core has flat wide core point.

Preferably, in the above-mentioned cap for brush rubber is housed.

Preferably, the above-mentioned cap for brush, penholder, nib and connecting rod are that plastic material is made.

Description of drawings

Fig. 1 is the utility model structural representation.

Mark among the figure: the 1-cap for brush; The 2-penholder; The 3-nib; The 4-connecting rod; The 5-spring; The 6-pen core.

The specific embodiment

Understand and enforcement the utility model for the ease of those of ordinary skills, the utility model is described in further detail below in conjunction with the drawings and the specific embodiments.

As shown in Figure 1, the utility model is a kind of propelling pencil, is made of the cap for brush 1, penholder 2 and nib 3 on the whole, and penholder 2 is a hollow column, inside is hollow tubular, and (direction from the cap for brush 1 to nib 3) is disposed with spring 5 from top to bottom, connecting rod 4 also has a plurality of pen cores 6 at penholder 2.Spring 5 upper ends head on the cap for brush 1, and the lower end is connecting connecting rod 4, in fact, under actual conditions, spring 5 is to be enclosed within on certain device that is similar to connecting rod, this connecting rod also with figure in connecting rod 4 interconnect, both are not integral productions, separately separate the heading in back.

A plurality of pen cores 6 that connecting rod is provided with for 4 times join end to end, and are sequentially arranged in the penholder 2 of hollow structure, and pen core 6 bottom stretches out outside the nib 3.As shown in Figure 1, pen core 6 has a plurality of, joins end to end one by one, and each pen core all passes through prior machine to be made, and has wide flat core point, and width is consistent with the option width of answering card, directly horizontal card-coating when making things convenient for answer.

The making material of whole pencil should select for use the lighter material cap for brush 1, penholder 2, nib 3 and connecting rod 4 to make for plastic material.

In use, by pressing the cap for brush 1, the new pen core 6 in the penholder 2 can automatically replace the nib 3 outer pen cores that stretch out, thereby realizes the process of new pen core replace old pen core.

Based on the utility model, can also carry out following improvement, as in the cap for brush 1 rubber being housed, but the cap for brush 1 is arranged to open-type, in keep small-sized rubber.

The utility model has designed a kind of brand-new pencil, by the design mouth substituting device, the pen core that interior dress is cut with wide core point, when answer, directly utilize the operation of ejecting automatically, can constantly keep the pen core of suitable answer, saved the time, and use and very convenient to carry.And the utility model design concept novelty is subjected to liking of child deeply, is extraordinary stationery in the usual life of people.
