Description

a variable pen

technical field

The utility model relates to the field of stationery, in particular to a variable pen.

Background technique

With the development of society, there are more and more types of pens, such as pencils, brushes, fountain pens, sticky notes, highlighters, ballpoint pens, hook pens, crayons and so on. Gel pens and ballpoint pens are commonly used today, while pencils are often used for drawing art drafts and drawing pictures.

However, the shape of the existing pen is relatively fixed and monotonous, and the color is monotonous, which cannot allow users to further explore the pen. For example, the utility model with the patent No. core, and a pen cap, and the pen cap is fixedly connected with the pen holder through an elastic connecting piece. When using the pen, the pen cap is covered on the upper end of the pen holder, and when the pen is not in use, the pen cap is covered on the lower end of the pen, and the pen cap is always fixedly connected with the pen holder.

and the invention with the patent number "200980105072.X" relates to a pen having a refill and a wood body surrounding the refill, wherein the pen has a substantially three-sided surface extending along the length of the pen with three gripping surfaces. shape, wherein at least two gripping surfaces are provided with gripping dimples arranged successively over at least a part of the length of the pen.

In addition, in order to increase the fun of the pen, decorations are usually added to the traditional pen, such as toy card head small objects, small game objects and so on. Even so, it is still not possible to stimulate the user's enthusiasm for learning. Therefore, how to change the shape of the pen to make it more attractive and satisfy the basic functions of the pen has become a technical problem to be solved urgently in this field.

A variable pen, comprising a pen holder and a refill, the inside of the pen holder is provided with an accommodating cavity, the pen core is fixed in the accommodating chamber of the pen holder, and the outside of the pen holder is wrapped with a soft material.

As an improvement of the above technical solution, the pen holder includes a first rod part at the top, a second rod part in the middle, and a third rod part at the bottom, and a soft material is provided on the outside of the second rod part.

As an improvement of the above technical solution, the third rod part is an inverted cone structure whose radius gradually increases from bottom to top.

As an improvement of the above technical solution, a pen cap matched with the lower end of the third rod part is also included.

As an improvement of the above technical solution, the upper end of the third rod part is provided with a protruding part with an external thread, and the inner ring surface of the lower end of the second rod part is provided with an internal thread matched with the external thread.

As an improvement of the above technical solution, the second rod is provided with concave-convex lines.

As an improvement of the above technical solution, the concave-convex lines are symmetrically arranged on both sides of the second rod part.

As an improvement of the above technical solution, the soft material is an ellipsoidal expansion structure.

As an improvement of the above technical solution, the first rod part is a handle structure with a curved arc.

The beneficial effect of the utility model is: by setting the soft material on the outside of the pen holder, the soft material has the characteristics of heating and deformation, cooling and fixing, so that the pen holder can be heated according to the needs, and then it can be made into the required shape. You can fabricate the appearance of the pen at will, which is interesting and fun, and greatly adds to the fun of the life of the pen.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural schematic diagram of an embodiment of the variable pen described in the present invention.

detailed description

Please refer to attached picture 1. It should be noted that the structures, proportions, sizes, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the present invention. Limiting conditions, so there is no technical substantive meaning, any modification of structure, change of proportional relationship or adjustment of size, without affecting the effect and purpose of the present invention, should still fall within the scope of the present invention. The disclosed technical content must be within the scope covered. At the same time, terms such as "upper", "lower", "left", "right", "middle" and other terms quoted in this specification are only for the convenience of description, and are not used to limit the practicable scope of the present invention. The change or adjustment of the relative relationship within the scope, without any substantial change in the technical content, shall also be regarded as the applicable scope of the present invention.

As shown in Fig. 1, a kind of follow-up pen of the present utility model comprises a pen holder and a pen core 1, and the inside of the pen holder is provided with an accommodation chamber, and the pen core 1 is fixed in the accommodation chamber of the pen holder, and the outside of the pen holder Set wrapped with soft material.

In the above scheme, by setting a soft material on the outside of the pen holder, the soft material has the characteristics of heating and deformation, cooling and fixing, so that the pen holder can be heated according to needs, and then it can be made into the desired shape, which can be fabricated at will.
