Description

Pen cap and pen holder integrated writing brush for arts and crafts

Technical Field

The invention relates to an industrial art tool, in particular to a cap and pen holder integrated writing brush for industrial art.

Background

The writing brush is a traditional writing tool derived from China, and is not only a Chinese character writing tool, but also a traditional Chinese painting tool. In the traditional drawing, no matter what the writing brush is, the line is basically sketched by the writing brush, the body structure is shaped, the object image is drawn by dipping the writing brush in water, regulating ink, chapping, wiping, dots, dyeing and the like, and the object image is drawn by the writing brush regulating color, separating dyeing, shading and the like.

The writing brush is made of a pen point Mao Zacheng of a beast and then stuck on a tubular pen holder. In order to protect the pen point, a manufacturer can sleeve the pen cap after the writing brush is manufactured, so that the pen point is prevented from being scattered or bent after touching other objects. The brush pen cap can be abandoned by the brush pen which is frequently used every day, because the brush pen is good after cleaning, the brush pen head contains moisture, and the brush pen is easy to wet and mould after being sealed. However, the writing brush which is not frequently used is required to be worn with a pen cap after the pen head is dried, so that the pen head is protected, and the service life of the writing brush is prolonged.

The brush caps matched with the writing brush in the market at present are separated from the pen holder and are easy to be confused or discarded. Because the paint dipped and dyed by each writing brush is different when the writing brush is used, the phenomenon that different paint reacts chemically after the cap is mixed can be caused, and the writing brush head is damaged. If can design a pen cap pen-holder integral type writing brush, open the pen cap when using the writing brush and expose the nib, after the writing brush uses to accomplish airing the nib, simple button operation or toggle operation, the pen cap on the pen-holder can be immediately with the nib seal, then will be very big facilitate the use to fully prolong the life of writing brush. The method has important significance for improving the technological content of the industrial art tool, reducing the damage and waste of the painting art tool, promoting the inheritance and development of art culture and the like.
