Abstract

The invention discloses an eraser device and a method for cleaning chippings. The eraser device comprises a shell body (1), a first gear (2) which is installed on the shell body (1) and partially protrudes out of the shell body (1), and at least one second gear (3) which is installed on the shell body (1) and is in transmission with the first gear (2) in a meshed mode, wherein the first gear (2) comprises first gear teeth (22) used for erasing pencil handwriting, tooth sockets of the first gear (2) and tooth sockets of the second gear (3) are used for containing the multiple chippings generated by erasing the pencil handwriting. The eraser device has the advantages that the structure of the first gear and the second gear is adopted, chippings generated when the first gear teeth erase the pencil handwriting can be absorbed in the tooth sockets of the first gear and the tooth sockets of the second gear respectively, and therefore automatic cleaning of the chippings is achieved. The method for cleaning chippings is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of stationery, and more specifically, relates to an eraser device and a method for cleaning debris. Background technique [0002] The eraser will produce debris in the process of wiping the pencil writing. If the debris is not cleaned in time, it is very easy to cause the paper surface to be untidy; if the debris falls on the ground, it will not only affect the cleanliness of the ground but also be difficult to clean. The eraser in the prior art has a device for cleaning debris, but in the process of use, the pencil writing is usually wiped first and then the debris is cleaned. However, the operation of this type of eraser for cleaning debris is cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an eraser device and a method for cleaning debris that are relatively simple for clearing debris in view of the defect that the above-mentioned ...
