Abstract

The utility model discloses a bidirectional adjusting eraser, comprising a hollow sheath and an eraser. The eraser is arranged in the sheath; the eraser and the inner wall of the sheath form yin-yang match; two ends of the sheath are opened and respectively communicated with a first adjusting opening and a second adjusting opening. The position of the eraser can be adjusted by the first adjusting opening and the second adjusting opening.

Description

The bidirectional modulation erasing rubber

Technical field

The utility model relates to a kind of erasing rubber that can two-wayly regulate, belongs to the optimization of erasing rubber technology.

Background technology

Erasing rubber is a kind of block structure of software, and shape is various, in actual use, has certain rigidity in order to make erasing rubber, all does thicklyer usually, and is also just bigger naturally with the contact area of paper.

During daily use, make mistakes when writing, or drawing the time makes mistakes, the scope of wiping if desired is less, and the position adjacent with fault domain just is easy to clip the position that should not wipe when word or picture are arranged.For the contact-making surface that makes erasing rubber and paper reduces, do the cross section of erasing rubber lessly, use inconvenience on the one hand, because erasing rubber will grasp use, too thin bad assurance; On the other hand, the hardness of erasing rubber itself is not high enough, easy flexural deformation firmly the time, and the real contact area during use is still bigger.Certainly, also can cut the shape that becomes to need to the area of section of erasing rubber and shape, but so not only waste but also bother.

Therefore, need to seek a kind of cross section and can do smallerly, can solve the hardness problem again, and erasing rubber easy to use.

Summary of the invention

The purpose of the utility model provides the less convenient again erasing rubber that can two-wayly regulate that uses of a kind of cross section.

The technical scheme of the utility model is: the bidirectional modulation erasing rubber; Be made up of hollow sheath 1 and erasing rubber 2, erasing rubber 2 is placed in the sheath 1 and uses, and erasing rubber 2 forms negative and positive with sheath 1 inwall and cooperates; Sheath 1 both ends open; Sheath 1 is provided with first and regulates mouthful 11 and second an adjusting mouth 12, makes the some of erasing rubber 2 expose out, and can regulate; Described first regulates mouthfuls 11 is communicated with an end opening of sheath 1, and described second regulates the other end open communication of mouth 12 and sheath 1; Described first regulates the both sides that mouthful 11 and second adjusting mouth 12 lays respectively at erasing rubber.

During adjusting, regulate mouth through the first adjusting mouth or second and stir erasing rubber, make erasing rubber move to correct position to the openend of sheath.

During use, pinch sheath, make jacket wall produce inside pressure and distortion, compress rubber is wiped it can not be moved.

Beneficial effect:

1, the both ends open of sheath, and be communicated with the first adjusting mouth and the second adjusting mouth respectively, can both regulate the position of erasing rubber through the first adjusting mouth and the second adjusting mouth.

The specific embodiment

As depicted in figs. 1 and 2, the bidirectional modulation erasing rubber is made up of hollow sheath 1 and erasing rubber 2, and erasing rubber 2 is placed in the sheath 1 and uses, and erasing rubber 2 forms negative and positive with sheath 1 inwall and cooperates.

As shown in Figure 3, sheath 1 both ends open, sheath 1 are provided with first and regulate mouthful 11 and second an adjusting mouth 12, make the some of erasing rubber 2 expose out, and can regulate; Described first regulates mouthfuls 11 is communicated with an end opening of sheath 1, and described second regulates the other end open communication of mouth 12 and sheath 1; Described first regulates the both sides that mouthful 11 and second adjusting mouth 12 lays respectively at erasing rubber.

Erasing rubber can get into from arbitrary openend of sheath.

The foregoing description only is to be used for the purposes of interpretation the utility model; And be not to be the restriction to the utility model, those skilled in the art are in the essential scope of the utility model; Make various variations or alternative, also should belong to the protection category of the utility model.

Claims
