Problems solved by technology

[0003] In order to solve the existing problems of erasable pencil refills, the present invention provides an erasable non-slip refill. The pencil surface pen with this refill has a particularly good use effect, even if the pencil is used for a short time. There will be no sliding core phenomenon, so it not only ensures the use effect of the color brush, but also prevents the occurrence of waste

Embodiment Construction

[0009] In the figure, the surface of its pen core 5 can be uneven small convex teeth 3 and small tooth grooves 4, and can also be uneven imprints, lines, grooves and rough surface layers; such a structure can completely Solve the sliding core phenomenon.

[0010] In the figure, the inner surface layer of the pen shell 1 can also be made into uneven imprints, lines, grooves and rough surfaces corresponding to the pen core 5 . Such a structure increases the reliability of preventing core slippage.

[0011] In the figure, all the gaps and surfaces between the pen case 1 and the pen core 5 must be filled with the adhesive 2, so that missing filling cannot occur.

Abstract

The present inventioninvention relates to a pencil lead, in particular to an erasable anti-slip pencil lead which can be erased after writing on paper. The present inventioninvention is characterized in that bossy teeth and tooth grooves are evenly spread on the outer surface of the pencil lead; when a pencil shell and the pencil lead match and form a pencil, a drawing pencil with such pencil lead is filled between the pencil shell and the pencil lead. Therefore, the use effect is very good: the lead does not slip even if the pencil is nearly used up and becomes very short. In this way, the present inventioninvention not only ensures the use effect of the color drawing pencil, but also prevents waste.

Description

technical field [0001] The invention relates to a pencil refill, in particular to an erasable non-slip refill which can be wiped off with an eraser after writing on paper. Background technique [0002] At present, some pencils and paintbrushes, especially some erasable colored paintbrushes, due to the problem of the material of the refill, the surface of the refill is usually very smooth, and the adhesion between it and the pen shell is very small. During use, slipping of the refill often occurs Phenomenon, especially in the later stage of use, its sliding core phenomenon is more prominent, which not only causes inconvenience to users, affects the use effect, but also causes waste because it can no longer be used. For this, there is no Very ideal solution. Contents of the invention [0003] In order to solve the existing problems of erasable pencil refills, the present invention provides an erasable non-slip refill. The pencil surface pen with this refill has a particular...
