Safety lock structure of electric pencil sharpener

Abstract

The invention discloses a safety lock structure of an electric pencil sharpener. The safety lock structure comprises a shell (1), an upper cover (2) and a partition plate (3), wherein a first limitingstructure and a second limiting structure are arranged on the top surface of the partition plate (3); a pen point shifting block (4), a pen inlet starting switch (5) and a rotary lock catch (6) are arranged on the partition plate (3); and the pen point shifting block (4) is located between the first limiting structure and the second limiting structure in the stop working state, one part of the pen point shifting block (4) is located at the top of a first through hole (3.1), and the pen point shifting block (4) abuts against a shifting piece of the pen inlet starting switch (5) and is far awayfrom the top of the first through hole (3.1) in the working state. According to the safety lock structure of the electric pencil sharpener, a mechanical structure is adopted to automatically switch on and switch off a power switch when the upper cover is opened or closed, reliability and durability are good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of stationery, in particular to a safety lock structure for an electric pencil sharpener. Background technique [0002] The electric pencil sharpener is used to cut wooden pencils so that the pen core is cut into a sharp shape. At present, when the upper cover of the electric pencil sharpener is opened, the power switch is disconnected, so as to avoid adverse consequences caused by misuse by consumers; at present, micro switches are generally used to realize, but the cost of micro switches is relatively high, and the life span is very limited. It is prone to failure after a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safety lock structure for an electric pencil sharpener that uses a mechanical structure to automatically turn on and off the power switch when the upper cover is opened or closed, has good reliability, good durabili...
