Eraser

Abstract

The invention discloses an eraser comprising an eraser core, a shell and an eraser seat. The thickness of the eraser core is 2-3 mm. When a user uses the eraser for erasure, the front part of the eraser core is pushed out for a part, and exposed out of a shell opening; since the eraser core is only 2-3 mm in thickness, and the contact area with paper surface is small, erasure can be achieved withsmall force; the eraser core is thin, so a continuous smooth plane with a large area can not be generated due to service wear; after the eraser core is worn, the user can press a pressing part to makethe eraser seat move toward the opening position, and the eraser core is pushed out, and continuously used; unnecessary waste caused by excessive contact area between the eraser and the paper surface, resulting in wear since many parts of the eraser come into contact with those parts which are not required to erase on the paper surface is not generated when the eraser is used, and the eraser corecan be replaced; and since the eraser core is thinner and the volume is smaller, the cost of a large amount of eraser materials can be saved.

Description

technical field [0001] The invention belongs to the technical field of stationery, in particular to an eraser. Background technique [0002] The eraser is a commonly used correction tool for erasing text written or drawn with a pencil. Current erasers often use a cuboid or cylindrical structure with a large cross-sectional area that is easy to hold. At the beginning of use, use the corners or sharper parts of the edge of the eraser to erase, and it can be effectively erased with a small force. Erase, and can erase smaller parts more accurately. However, the corners or sharper parts of the eraser are worn during use, and the entire surface forms a smooth continuous curved surface. When erasing, it needs to use greater force, and it is difficult to accurately erase the smaller parts. When erasing, many parts on the eraser contact and wear with parts that do not need to be erased on the paper, resulting in unnecessary waste. Contents of the invention [0003] Purpose of th...
