Abstract

The utility model relates to an eraser with a clamping type sheath. The eraser comprises a hollow sheath and an eraser, wherein openings are formed at the two ends of the sheath, a clamping groove is arranged on the side wall of the sheath, and the eraser is clamped through the clamping groove, so that the eraser is less prone to slipping out of the sheath.

Description

The erasing rubber of strap clamp compact form sheath

Technical field

The utility model relates to a kind of erasing rubber of strap clamp compact form sheath, 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 erasing rubber of the convenient strap clamp compact form sheath that uses again of a kind of cross section.

The technical scheme of the utility model is: the erasing rubber of strap clamp compact form sheath, to form by hollow sheath 1 and erasing rubber 2, and sheath 1 both ends open also is provided with a clamping slot 11 on sidewall; Described clamping slot 11 is communicated with the both ends open of sheath and is parallel with the axis of sheath; Described erasing rubber 2 gets into from arbitrary end opening of sheath 1, during adjusting, stirs the erasing rubber that exposes outside clamping slot, makes erasing rubber move to correct position to the openend of sheath; During use, pinch sheath, make sheath produce inside extruding force and clamp erasing rubber, erasing rubber in use can be moved.

The axis of erasing rubber is positioned at sheath 1, and the erasing rubber that exposes outside clamping slot is less than the half the of erasing rubber.

The openend of described sheath 1 is circular arc or triangle.

The horizontal cross-section of described sheath 1 is circle or ellipse or polygon.

Beneficial effect:

1, on sheath, is provided with clamping slot, clamps erasing rubber, make it to be difficult for skidding off sheath through clamping slot;

2, the convenient adjusting stirred the erasing rubber that exposes outside clamping slot, moves it the openend correct position;

Pinch sheath when 3, using, the stressed compress rubber of clamping slot is wiped, and erasing rubber can not moved;

4, because sheath has certain intensity, overcome the not enough problem of hour hardness of erasing rubber cross-sectional area, can use the less erasing rubber of sectional area, wiping in smaller scope and do not influence surrounding enviroment.

The specific embodiment

As depicted in figs. 1 and 2, the erasing rubber of strap clamp compact form sheath is made up of hollow sheath 1 and erasing rubber 2, and sheath 1 both ends open also is provided with a clamping slot 11 on sidewall; Described clamping slot 11 is communicated with the both ends open of sheath and is parallel with the axis of sheath; Described erasing rubber 2 gets into from arbitrary end opening of sheath 1, during adjusting, stirs the erasing rubber that exposes outside clamping slot with hand or instrument, makes erasing rubber move to correct position to the openend of sheath; During use, pinch sheath, make sheath produce inside extruding force and clamp erasing rubber, erasing rubber in use can be moved.

The openend of described sheath 1 is circular arc or triangle.With the triangle is example, during use, when needing the wiping area big, can select for use the Chang Bianchu of erasing rubber to go to wipe, and the area that needs wiping hour can select for use the erasing rubber minor face to go to wipe.Along with the wearing and tearing of using, the shape of erasing rubber termination also can change, at this moment, as long as adjust the needs that the contact angle of erasing rubber and paper just can satisfy the wiping area as required in good time.

Like Fig. 3, Fig. 4 and shown in Figure 5, the horizontal cross-section of described sheath 1 and erasing rubber is circle or ellipse or polygon.

Sheath adopts plastics or sheet metal to make, and during use, pinches sheath and erasing rubber, and the sheath compress rubber is wiped, and makes erasing rubber be difficult for sliding.

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.
