Abstract

The invention relates to a novel eraser. The novel eraser comprises a box body and a plurality of eraser bodies in different shapes. The side wall of the box body is provided with cavities of the same number as the eraser bodies and used for storing the eraser bodies. The cavities are the same as the eraser bodies in structure and slightly larger than the eraser bodies in size. The eraser bodies are in the shape of triangular prisms, quadrangular prisms, cylinders and cones of different sizes. According to the novel eraser, the box body is provided with the multiple cavities so that the different-size and different-shape eraser bodies can be placed in the same box body, and the various eraser bodies are placed separately, so that distinguishing is easy, and missing is not liable to occur. In addition, the eraser bodies are in the shape of the triangular prisms, the quadrangular prisms, the cylinders and the cones of different sizes so that people can erase objective writing conveniently and accurately, errors in a precise hand drawing are effectively erased, correct and effective parts are prevented from being erased, the workload is reduced, and the work efficiency is greatly improved.

Description

A kind of New type rubber eraser

Technical field

The present invention relates to a kind of New type rubber eraser, belong to technical field of stationery.

Background technology

Rubber is instrument when conventional study stationery and work, but the most build of current rubber is all relatively larger, when accurate Freehandhand-drawing mapping, when some tiny places are carried out erasing amendment, it is easy to wipe out the line not needing wiping, also again to draw afterwards, add unnecessary workload, greatly have impact on drawing efficrence.

It addition, current rubber be mostly exposed outside, the at most also simply upper wrapping paper of packaging, exposed be for a long time very easy to dirty outside so that rubber erasing time, the place needing amendment is caused smudgy, affects writing effect.

Summary of the invention

The technical assignment of the present invention is for above-mentioned deficiency of the prior art, it is provided that a kind of protect rubber cleaning, wiping effect is good, efficiency is high New type rubber eraser.

For achieving the above object, the technical solution used in the present invention is:

A kind of New type rubber eraser, including box body and some difform rubber bodies, the sidewall of described box body is provided with the cavity for depositing rubber body with rubber body equal number, and described cavity is identical with the structure of rubber body, size is slightly larger than rubber body.

Mistake for convenience of the accurate Freehandhand-drawing mapping of erasing, the triangular prism being shaped as varying in size of described rubber body, quadrangular, cylindrical and conical, so can ensure that people utilize rubber tooth shape, the different size of different size of writing to writing, the figure of different in width and lines to carry out wiping.

For ease of making, packing box and transport, described box body is circular or rectangle.

Preferably, described box body is circular, and cavity is 6 rectangular pyramid shapes, and the cone angle of described rectangular pyramid is incremented by successively.

Preferably, described box body is rectangle, and described cavity has some triangular pyramids, rectangular pyramid, cylindrical and conical.

The Advantageous Effects of the present invention: the present invention, by arranging multiple cavity on box body, it is possible to different size, difform rubber being placed in a box, various rubbers are separated, both easily distinguishable, is not easy again to lose; Additionally, the triangular prism being shaped as varying in size of rubber body, quadrangular, cylindrical and conical, the different size of writing write, the figure of different in width and lines can be carried out wiping, even if using a period of time, also can present the corner angle of different angles, conveniently making people that target writing is carried out wiping in short supply, effectively clash the wrong part in accurate Freehandhand-drawing mapping, avoid wiping out correct effective part, reduce workload, be greatly improved work efficiency.

Fig. 2 is the structural representation of the box body of the embodiment of the present invention one;

Fig. 3 is the structural representation of the embodiment of the present invention two;

In figure: 1: box body; 2: cavity; 3: rubber body.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail.

Embodiment one:

Shown in Fig. 1, Fig. 2, a kind of New type rubber eraser, including flat rectangular box and 8 and difform rubber body, the sidewall of described box body is provided with 8 cavitys for putting rubber body, the structure of cavity is identical with the structure of rubber body, size slightly larger than rubber body, the shape of rubber body has triangular pyramid, rectangular pyramid, cylindrical and conical, it is ensured that the rubber body of different structure is placed in different cavitys, easily distinguishable, it is not easy again to lose; Additionally different size of writing, the figure of different in width and lines can be carried out wiping by the rubber body of different structure, it is to avoid more wipe or few wipe, thus improving work efficiency.

Embodiment two

Shown in Fig. 3, a kind of New type rubber eraser, including flat round box and different size of rectangular pyramid rubber body, the circumferential side wall of box body is uniformly provided with 6 cavitys for putting rubber body, the structure of cavity is identical with the structure of rubber body, size is slightly larger than rubber body, the cone angle of rectangular pyramid rubber body ranges for 10-60 degree, to meet different demands.

The present invention can be effectively protected rubber cleaning, it is prevented that rubber is lost, and additionally rubber body is set as different structures; can effectively clash the wrong part in accurate Freehandhand-drawing mapping; avoid wiping out correct effective part, reduce workload, be greatly improved work efficiency.

Claims
