Abstract
The utility model relates to an automatic pencil sharpener capable of automatically sharpening pencils by rotation. On the basis of the technique of a hand operated pencil sharpener, a small motor is added to drive a rotary hobbing cutter, and a switch for starting the small motor is arranged in a tapered hole and is connected with the motor by an electric wire, a pencil can extend into the tapered hole, and an original hand operated device is removed. The utility model uses a rotation loss deceleration method to make the rotary speed of the motor match the rotary speed of the hobbing cutter which sharpens the pencil by rotation. The utility model has the advantages that pencils extending into the tapered hole is safely, conveniently and rapidly sharpened by rotation by the hobbing cutter at high speeds in seconds. When a pencil is drawn out, the switch is turned off naturally, and thus the remaining pencil length can be reduced. The utility model is a tool for sharpening pencils by rotation.
Description
Technical field
The utility model relates to a kind of " propelling pencil revolves " that sharpens a pencil.
Background technology
The pencil sharpener that sharpens a pencil of present domestic use is a hand-rail type.This hand-rail type pencil sharpener operates and bothers, and last pencil stub 5-6cm length just must abandon.This hand pencil sharpener exists troublesome poeration and waste pencil stub two big shortcomings.
Summary of the invention
The utility model purpose be for vast consumer provide a kind of easily and fast, handy and " propelling pencil revolves " of saving pencil stub, can solve the shortcoming that exists in the prior art effectively.
The purpose of this utility model is to remove manual setter, drives pencil with a miniature motor and revolves movement, adopts the retardation method that throws switch to make the rotating speed of miniature motor and revolve a movement rotating speed and is complementary.Be achieved through the following technical solutions, it comprises that the hobboing cutter that driven pulley drives revolves pen core, miniature motor, from touch domatic snap switch, pencil bits end bucket box, housing.It is characterized in that: a domatic spring loaded switch is set putting in the taper hole of pencil.Pencil is put in the taper hole, and this operation that sharpens a pencil is finished in rolling thereby motor rotates the drive hobboing cutter.
The utility model is owing to adopt said structure, whole pencil is rotated with on the desk that fixes on study usefulness or connects AC power on the desk to get final product, and also can drive with dry cell.It has convenient, fast, save time, laborsaving and save the last length of pencil stub, advantage such as power consumption is extremely low.
