Example Embodiment

[0020] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.

[0021] Such as Figure 1~7 As shown, an electric pencil sharpener includes a casing 1 and a pencil sharpening mechanism 2 arranged in the casing 1. A suction cup 11 is respectively provided at the four corners of the bottom of the casing 2 to enable the sharpening The pen set is firmly placed on a flat surface, and the casing 2 is provided with a sharpening hole 11 for inserting a pencil. The pencil sharpening mechanism 2 includes a knife holder 20 and a hob 21. One end of the knife holder 20 is provided with a working hole 25 for inserting a pencil. The working hole 25 communicates with the pencil sharpening hole 11, and the working hole 25 is provided below The cutter seat 22 with a cutter shaft 23 is sheathed with the hob 21 mentioned above, and the hob 21 can rotate around the cutter shaft 23.

[0022] Further, the other end of the tool holder 20 is pr...

Abstract

The invention relates to an electric pencil sharpener which comprises a machine shell and a pencil sharpening mechanism arranged in the machine shell. The pencil sharpening mechanism comprises a cutter frame, a hobbing cutter, a work hole and a transmission assembly. A first transmission part in the transmission assembly can abut against one end of a push block, and the other end of the push blockabuts against a pencil point of a pencil. A second transmission part in the transmission assembly can abut against one end of a cutter shaft, and the first transmission part and the second transmission part are in linkage. During pencil sharpening, the pencil point pushes the push block, the push block pushes the first transmission part, the first transmission part drives the second transmissionpart and enables the second transmission part to push the cutter shaft, and then the cutter shaft moves in the direction away from the second transmission part; an elastic reset part is stressed tillthe cutter shaft is located on a cutter seat through a locating structure, the cutter shaft is located, the hobbing cutter is separated from the cutter shaft, and therefore effective cutter separationis achieved; and the sharpness of a pencil lead is effectively controlled, and the situation that sharpening is excessive or the sharpness is not enough is avoided.

Description

technical field [0001] The invention relates to the field of stationery, in particular to an electric pencil sharpener. Background technique [0002] A pencil sharpener generally includes a main body, a pen feeding mechanism, a pencil sharpening mechanism, and a pencil scrap box, etc., wherein the pencil sharpening mechanism is the key structure of the pencil sharpener. Existing pencil sharpening mechanism generally comprises knife rest and the hob that is arranged on the knife rest, and when sharpening a pencil, the blade of hob cuts the pencil of working hole. Such as the Chinese utility model patent "electric pencil sharpener" whose patent number is ZL200620102134.5 (authorized announcement number is CN 2892505Y), and the Chinese utility model patent "an electric pencil sharpener" whose patent number is ZL201420643456.5 (authorized announcement number is CN204210218 U). Patents such as pencil sharpener " all disclose existing pencil sharpening mechanism. [0003] When t...
