Description

A kind of multifunctional eraser is wiped

Technical field

The utility model relates to a kind of study article, and a kind of multifunctional eraser is wiped specifically.

Background technology

When using erasing rubber to wipe vestige, both needed large tracts of land to wipe, and also need to wipe the details position is meticulous, and common erasing rubber generally all can only satisfy wherein a kind of requirement.In the process of using erasing rubber, rubber can stay chip on paper, is not good at if handle, and these chips can be left a trace at paper, even the paper of making dirty, cause paper unclean, influence attractive in appearance.

In daily learning process, may often need carry out simple linear measure longimetry, and it is cumbersome to carry ruler.

The utility model content

For addressing the above problem, the utility model provides a kind of multifunctional eraser to wipe, and this erasing rubber can not only be used for large tracts of land to be wiped, and also can wipe for detail section is meticulous, the energy cleaning powder drops on the chip on the paper simultaneously, and can be used for simple short-range linear measure longimetry.

The technical scheme that the utility model solves above technical problem is: a kind of multifunctional eraser is wiped, and is made up of erasing rubber and erasing rubber cover, and the erasing rubber cover ring set is at described erasing rubber outer surface.

All right, erasing rubber cover, erasing rubber are shaped as triangular prism, and the triangular prism base is right angled triangle.

All right, be carved with the rule that tolerance length is used on the erasing rubber cover.

All right, also be provided with a groove on the erasing rubber cover, both sides are respectively arranged with track in the groove, and the hair brush handle two ends embed in the track by the slide bar on the slide block, and hair brush handle is provided with hairbrush.

The beneficial effects of the utility model are: use above structure, comprise erasing rubber and erasing rubber cover composition, the erasing rubber cover ring set can strengthen the intensity of erasing rubber at the outer surface of erasing rubber, reduces erasing rubber in the distortion of use, the use that Convenient rubber is wiped.Erasing rubber is shaped as triangular prism, and the base is right angled triangle, makes that erasing rubber one side is thicker, is used for large tracts of land and wipes, and opposite side is thinner, is used for that the details position is meticulous wipes.Erasing rubber cover one side arranges a groove, a hairbrush is installed in the groove, the chip that produces when being used for the use of cleaning erasing rubber, both sides are respectively equipped with track in the groove, the hair brush handle two ends are fixed on the slide block, embed in the track by slide bar, slide block can slide by slide bar in orbit, when needing to use hairbrush, it can be released along track in groove, when not needing to use hairbrush, can push back in the groove, play the effect of protection hairbrush; Erasing rubber cover indicates scale, can be used for simple short distance linear measure longimetry.

Erasing rubber is the thin shape of the thick side of a side, having satisfied large tracts of land simultaneously wipes and the meticulous requirement of wiping of details, simultaneously, the hairbrush that erasing rubber cover is installed above can clean the erasing rubber chip that is scattered in the erasing rubber use on the paper, and rule can be used for simple short distance and measures.The utility model is simple in structure, and is easy to use, with low cost.

Description of drawings

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

Fig. 2 is the utility model track schematic diagram.

Among the figure: erasing rubber 1, erasing rubber cover 2, groove 3, hairbrush 4, track 5, hair brush handle 6, slide bar 7, slide block 8, rule 9.

The specific embodiment

As shown in Figure 1 and Figure 2, be made up of erasing rubber 1 and erasing rubber cover 2, erasing rubber cover 2 ring sets are at described erasing rubber 1 outer surface.Erasing rubber cover 2, erasing rubber 1 are shaped as triangular prism, and the triangular prism base is right angled triangle; Be carved with the rule 9 that tolerance length is used on the erasing rubber cover 2, also be provided with a groove 3 on the erasing rubber cover 2, both sides are respectively arranged with track 5 in the groove 3, and hair brush handle 6 two ends are by in the embedding track 5 of slide block 8 upper slide bars 7, and hair brush handle 6 is provided with hairbrush 4.

Operation principle: in use; erasing rubber 1 is shaped as triangular prism; the triangular prism base is right angled triangle; erasing rubber 1 a thick side is done large-arealy to wipe, a thin side does that details is meticulous wipes, and in use, rubber is wiped 1 and produces some rubber chips; hairbrush 4 in the erasing rubber cover groove 3 is released; the chip that is scattered on the cleaning paper pushes back hairbrush in the groove 3 after cleaning finishes, with protection hairbrush 4.When using this multifunctional eraser to wipe, can satisfy large tracts of land and wipe and meticulous requirement of wiping, and the chip that can use brush cleaning to be scattered, can also carry out simple short distance linear measure longimetry with the rule 9 on the erasing rubber cover.
