Description
Technical Field
The utility model relates to an office supplies technical field specifically says that a novel rubber.
Background
The eraser is a stationery made of rubber and can wipe off the writing trace of the pencil. The eraser has various types, different shapes and colors, common erasers, art-specific erasers of 2B, 4B, 6B and the like for painting, plastic erasers and the like. The common rubber or art special rubber in the prior art is generally in a block shape and has edges; when the pencil writing trace or the drawing trace is erased, the edge angle or the edge of the eraser is generally erased, and after the eraser is used for a period of time, the edge angle or the edge can be slowly abraded, so that the edge angle or the edge is in a circular arc shape with a larger area, and the writing or the drawing trace at the drawing corner or a smaller position is inconvenient to erase. Particularly, in professional art painting, useless and very fine sketch lines in the artwork need to be erased, and if the edge area of the eraser is too large, useful sketch lines around the useless sketch lines can be erased during erasing, so that much inconvenience is brought to a painter; after the edge is ground off, a new edge is formed by cutting off the ground edge with the aid of a blade to erase the edge, which is inconvenient to operate. At present, some multi-edge erasers are also available, and one edge of the eraser is abraded and then erased by using the other edge, for example, the national intellectual property office discloses a patent application with an authorization publication number of CN202337143U and a name of a practical eraser, the side wall of the eraser is provided with a plurality of tooth-shaped edges, but in the actual use process of the eraser, when another edge is abraded and used, the previous edge or the edge around the previous edge can also erase surrounding writing or drawing traces, so that accurate erasing of the drawing edges or the drawing traces of a small position can not be satisfied. Moreover, the block-shaped eraser is independent from the pencil, and the eraser needs to be independently placed after being used, so that the eraser is easy to lose.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is, overcome the defect of above prior art, provide one kind and have a plurality of arriss of erasing, and an arris grinds the back and need not can easily tear this arris with the help of the blade, utilizes the novel rubber that next arris erased.
The technical solution of the utility model is to provide a novel rubber with following structure: the rubber body is provided with at least one section of tearable part extending along the length direction of the rubber body, the tearable part comprises at least one rubber monomer, at least one peripheral wall of the rubber monomer is provided with a tapered erasing edge with a thin outer part and a thick inner part, and a connecting part of the rubber monomer and the rubber body is provided with a concave tearable groove for tearing the rubber monomer from the rubber body.
