Description

Double-knife multifunctional pencil sharpener

Technical Field

The utility model belongs to the technical field of the stationery technique and specifically relates to a double knives multifunctional pencil sharpener.

Background

The pencil sharpener, also called a pencil sharpener or a pencil sharpener, is a tool for sharpening a pencil, and the pencil sharpener is divided into an electric sharpener and a manual sharpener, wherein the manual sharpener is divided into a hand sharpener and a manual sharpener without hand cranking. Hand pencil sharpener passes through the twist grip, can accomplish and dig a function, can make closed structure usually, and the bits box is the mode of horizontal pull for the pencil piece is difficult for scattering.

The existing pencil sharpener comprises a shell, a pencil sharpening assembly, a pencil feeding assembly and a pencil scrap box, wherein the pencil sharpening assembly, the pencil feeding assembly and the pencil scrap box are arranged in the shell, and only one pencil sharpening assembly is arranged, so that the planing speed is low, the planing efficiency is low, and the requirements of children on the higher and higher performance of the pencil sharpener cannot be met.

Thus, the prior art is waiting for a move to and improvement.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists among the prior art, the utility model aims at providing a many functional pencil sharpener of double knives that planing is fast, planing is efficient.

In order to achieve the above object, the utility model adopts the following technical scheme:

a double-blade multifunctional pencil sharpener comprises a shell, two pencil feeding assemblies and a pencil scrap box which are arranged in the shell, and a handle which is arranged outside the shell, wherein the shell comprises a shell body and a rear cover which is detachably connected to the rear end of the shell body, a gear set is arranged on the rear cover, the handle drives the two pencil sharpening assemblies which are accommodated in the shell through the gear set, the gear set comprises a driving gear, a first transmission gear, a second transmission gear, a first driven gear and a second driven gear which are rotatably arranged on the rear cover, the driving gear is coaxially arranged with one end of the handle, the driving gear is meshed with the first transmission gear and the second transmission gear, the first transmission gear and the second transmission gear are respectively meshed with the first driven gear and the second transmission gear, and the first driven gear is coaxially arranged with one pencil sharpening assembly, the second driven gear and the other pencil sharpening component are coaxially arranged.

Preferably, the shell is provided with three knob mounting holes, the rear cover is movably provided with three knobs, one ends of the knobs are inserted into the three knob mounting holes, the knob mounting holes are relatively provided with two clamping grooves, and the knobs are provided with two bulges matched with the corresponding two clamping grooves.

Compared with the prior art, the beneficial effects of the utility model are that:

due to the adoption of the structural design, the handle drives the two pencil sharpening components through the gear set, so that the planing speed and the planing efficiency are greatly improved, and the requirements of children on the higher and higher pencil sharpener are met.
