Abstract

The utility model discloses a multifunctional eraser. The multifunctional eraser comprises an eraser body, a connecting shell and a brush. Appearance of the eraser body is a cube, appearance of the connecting shell is a cube, grooves are formed in two ends of the connecting shell, the size of the internal sections of the grooves is equal to that of the section of the eraser body and the section of the brush and a bar-type protrusion is formed inside each groove. A small hole is formed in the surface of the connecting shell and the small hole is cylindrical. According to the multifunctional eraser, through research of the problem that eraser crumbs are hard to clear when an existing eraser is used, the brush is combined with the eraser, and therefore eraser crumbs generated in the process of usage of the multifunctional eraser can be removed through the brush. The multifunctional eraser not only guarantees cleanness and tidiness of paper but also is free from pollution to both hands and keeps the hands clean.

Description

A kind of multifunctional eraser is wiped

Technical field

The utility model relates to erasing rubber, relates in particular to a kind of multifunctional eraser and wipes.

Background technology

Pencil is the first-selected writing implement of students always, because it has the characteristics of easily wiping.And with pencil matching used Aces Go Places no more than rubber, the writing that rubber can Clean-pencil writes out, for students unavoidably mistake can appear in learning process, at this moment rubber is exactly only choosing, rubber can the pencil writing, be because when use is write, the graphite of pencil can be stayed in the fiber of paper, and the natural rubber in the rubber or artificial rubber can be lived the paper fibers encapsulation on graphite and graphite top layer, so just reached the purpose of eliminating the pencil writing, but same problem of the thing followed is exactly after having wiped rubber, the surface of paper has the chip of some rubbers, and such chip is messy but also be adsorbed on the paper, no matter is to blow or brush lightly with hand with mouth, all can not very thoroughly must dispose, but also blackout paper easily.

The utility model content

At the problems referred to above that existing erasing rubber in use exists, the utility model provides a kind of multifunctional eraser to wipe.

The technical scheme that the utility model technical solution problem adopts is:

A kind of multifunctional eraser is wiped, and comprises rubber, connects shell and brush, and wherein, described rubber is cube shape, and described connection shell is cube, and two ends are provided with groove, and described groove is connected with brush with described rubber respectively.。

Described multifunctional eraser is wiped, and wherein, is provided with the strip bulge thing in the groove of described connection shell.

Described multifunctional eraser is wiped, and wherein, the cross-sectional sizes of described connection shell groove is identical with the cross-sectional sizes of described rubber and described brush.

Described multifunctional eraser is wiped, and wherein, the surface of described connection shell is provided with cylindrical hole, and described cylindrical hole cross-sectional sizes is identical with the penholder cross-sectional sizes of pencil.

Technique scheme has following advantage or beneficial effect:

The utility model connects shell by install one additional at erasing rubber, and be provided with brush at the other end that connects shell, in the use of rubber, clear up the rubber bits that rubber left behind by brush, because the brush bristles quality is light, and is rich in toughness, therefore when removing the rubber bits, can play good effect, in addition, also be provided with the cylinder aperture on the surface that connects shell, aperture can be connected and fixed with the pencil end, and it is also very convenient that erasing rubber is taken in no the time.

Description of drawings

Fig. 1 is the structural representation that the utility model multifunctional eraser is wiped.

Fig. 2 is the structural representation that connects shell in the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.

As shown in Figure 1, the utility model is that a kind of multifunctional eraser is wiped.Comprise rubber 1, connect shell 2 and brush 3.The profile of rubber 1 is cube, the profile that connects shell 2 is cube, be provided with groove at the two ends that connect shell 2, the size in inside grooves cross section is consistent with rubber 1 and brush 3 cross-sectional sizes, as shown in Figure 2, be provided with strip bulge thing 4 in the inside of groove, be provided with aperture 5 on the surface that connects shell 2, aperture 5 is cylinder.

Rubber 1 packs into by nested mode with brush 3 and is connected shell 2 inside grooves, be provided with strip bulge thing 4 owing to connect shell 2 inside grooves, when fixedly rubber 1 and brush 3, can increase the frictional force of contact-making surface, make fixing more firm, the brush of brush 3 adopts elastomeric soft material to make, make brush 3 when brushing the rubber bits, can closely be adjacent to paper, thereby the rubber bits can be removed efficiently.By connecting the cylinder aperture 5 that shell 2 surfaces arrange, can when not use erasing rubber, erasing rubber and pencil end be connected and fixed, thereby be convenient to take in, be not easy to lose.

In sum, the utility model is that a kind of multifunctional eraser is wiped, study by the problem that erasing rubber in the past in use is difficult to remove the rubber bits, with brush 3 and rubber 1 combination, make to brush the rubber bits that in the rubber use, produce by brush 3, both guaranteed the clean and tidy of paper, simultaneously do not pollute both hands again, kept the clean of both hands.

The above only is the utility model preferred embodiment; be not so limit claim of the present utility model; so the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the present utility model.
