Abstract

The utility model provides an automatic type eraser which comprises a pen head, a pen rod and a pen cap connected to the tail end of the pen rod. The pen rod is a hollow cylindrical object. A spring, a refill protecting tube and an eraser are arranged in a direction from the pen cap to the pen head in sequence. One end of the eraser stretches out of the pen head, and the other end of the eraser is connected with the refill protecting tube. The refill protecting tube is connected with the pen cab through the spring. The eraser is in a long and thin cylinder shape. Due to the fact that when the automatic type eraser is used, both hands of a user do not have to touch a drawing paper, so that line uniformity cannot be destroyed and the drawing paper cannot be stained. So draftman can use the eraser more handily.

Description

automatic eraser

technical field

The utility model relates to an eraser, in particular to an automatic eraser.

Background technique

The erasers currently on the market are all blocky. The lines in the manual work are very dense. When modifying the lines, it is easy to erase other adjacent lines with the block eraser, thus destroying the uniformity of other lines. , although some rulers on the market now have some line specifications that allow us to cover the surrounding lines when modifying, but because the ruler needs to move back and forth on the drawing, the drawing is often dirty due to the existence of thick lines.

Utility model content

In order to solve the problems existing in the prior art, the utility model proposes an automatic eraser, which will neither destroy the uniformity of the line nor dirty the drawing when used, which greatly facilitates manual drawing .

An automatic eraser, including a pen tip, a pen barrel and a cap connected to the end of the pen barrel. The pen barrel is a hollow column, and a spring, a core tube and an eraser are arranged in sequence from the cap to the tip of the pen. One end of the eraser protrudes from the tip of the pen. , and the other end is connected with the protective core tube, and the core protective tube is connected with the pen cap through a spring.

Preferably, the rubber is elongated and cylindrical.

Since the automatic eraser is in use, the user's hand does not need to touch the drawing, so neither the uniformity of the line nor the staining of the drawing will be damaged, and the drawing person can use it more easily.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the perspective view of the rubber of the present utility model.

Detailed ways

As shown in Figure 1, an automatic eraser includes a pen tip, a pen holder and a pen cap connected to the end of the pen holder. One end of 3 stretches out the nib, and the other end is connected with the core-protecting tube 2, and the core-protecting tube 2 is connected with the pen cap by the spring 1.

The shape of the eraser 3 is elongated flat or elongated cylinder. Preferably, the eraser 3 is elongated and cylindrical, which is conducive to better wiping lines.

The eraser is processed into a slender cylindrical shape like a mechanical pencil lead. The strength and smoothness of the slender cylindrical eraser meet the requirements for the use of an automatic eraser. The automatic eraser performs the function of an eraser, and finally it can be used like a block rubber The purpose of the automatic eraser.

When in use, the eraser is installed in the pen holder. Since the automatic eraser is in use, the user's hand does not need to touch the drawing, so that the uniformity of the line will not be destroyed, and the drawing will not be dirty. More handy.

It should also be noted that under the teaching of this specification, any equivalent replacement or obvious modification of the utility model made by those skilled in the art shall fall within the protection scope of the utility model.
