Electric pencil sharpener

Abstract

An electric pencil sharpener comprises a casing (1) as well as a base (2), a motor (3), a tool rest (4) and a transmission assembly which are located in the casing (1), wherein the base (2) is connected with the casing (1), the motor (3) and the transmission assembly are connected onto the base (2), the tool rest (4) is rotationally connected with the casing (1), a pencil stopping block (5) is arranged in the tool rest (4), the tool rest (4) is connected with an output end of the transmission assembly, a micro-switch (6) is arranged in the casing (1) and is electrically connected with the motor (3), a link mechanism for controlling the micro-switch (6) is arranged on the base (2), one end of the link mechanism is attached to the micro-switch (6), and the other end of the link mechanism abuts against the pencil stopping block (5) and the output end of transmission assembly. Compared with the prior art, the electric pencil sharpener has the characteristics that a control mechanism is simple, fewer welding spots exist, the use stability is better, the electric pencil sharpener is easily and conveniently used, the assembling efficiency of workers can be substantially improved, and the cost is lower.

Description

technical field [0001] The invention belongs to the technical field of stationery, in particular to an electric pencil sharpener. Background technique [0002] At present, the electric pencil sharpeners of the prior art can be divided into manual electric pencil sharpeners and automatic electric pencil sharpeners according to the function of use; Pencils; and automatic electric pencil sharpeners are divided into self-starting electric pencil sharpeners and sharpening stop electric pencil sharpeners. Self-starting electric pencil sharpeners refer to pencil sharpeners that can be started by inserting a pencil. The user needs to judge by himself, and the electric pencil sharpener will stop working when the pencil is pulled out; It also has the function of self-starting. When using the manual electric pencil sharpener and the self-starting electric pencil sharpener, the user needs to pay attention to the sharpening situation of the pencil sharpener at any time, so as to close ...

AI Technical Summary

Problems solved by technology

When using the manual electric pencil sharpener and the self-starting electric pencil sharpener, the user needs to pay attention to the sharpening situation of the pencil sharpener at any time, so as to close the pencil sharpener in time, otherwise the pencil is easily sharpened to the point that it cannot be used directly, so it is more troublesome to use ; and although the sharpening stop electric pencil sharpener can automatically control the whole pencil sharpening process, the structure of the whole control mechanism is complicated, and at least two switches are required to be used together, and even an integrated circuit board and a single-chip microcomputer are required to be controlled. The overall volume of the pencil sharpener is larger, and the cost of the pencil sharpener is greatly increased, and because there are many lines, the solder joints between the lines also increase, and most of the pencil sharpeners are used by primary and middle school students. The environment is relatively complex, integrated circuit boards and single-chip microcomputers have a greater impact on the environment, and the more solder joints, the easier it is for the solder joints to fall off, so the use stability is poor, and it also greatly increases the difficulty of assembly for workers. less efficient
