Abstract

The utility model relates to an electrical pencil plane which is used for automatically sharpening a pencil, which is composed of a shell, a positioning hole, a power circuit, a sharpening head of a pencil plane, a drive circuit and a power switch. Because the utility model adopts electric power as power to drive and adopts the sharpening head of a pencil plane for sharpening a pencil nib of the pencil by a sharpening method, the electrical pencil plane can conveniently and uniformly carry out work. The power switch is positioned on the inner side of the positioning hole. Therefore, after the pencil is inserted into the positioning hole, because of own pressure of the pencil, a contact piece switch is switched on for realizing the function of automatically sharpening the pencil. After the pencil nib is sharpened, powder can be poured from a square hole on the shell. In this way, the convenience, the high speed and the automation of sharpening the pencil can be completely realized.

Description

A kind of electronic pen digs

The utility model relates to a kind of device that sharpens a pencil, and a kind of specifically electronic pen that sharpens a pencil automatically digs.Pencil is a thing commonly used in the routine work study, and especially the use in middle and primary schools is especially extensive.Yet thing followed problem then is the problem that sharpens a pencil of students.Owing to use frequent, almost each student is anxious for sharpening a pencil, the instrument that sharpens a pencil also is of a great variety at present, they are to form with a small blade and a conical locating hole, during use pencil put into locating hole and rotate continuously and utilize the blade nib of fining away, be beneficial to the purpose of writing to reach.Popular propelling pencil also has similar pen to dig at present, and its principle also is the same.The shortcoming that this pen digs is because what use is blade, can not well grasp dynamics when sharpening a pencil, and especially for propelling pencil, because pen core is thinner, is easy to cut disconnected.

The purpose of this utility model is that a kind of pen that can dynamics sharpens a pencil uniformly of invention digs, and especially can easily cut nib fast for propelling pencil.

The utility model can be achieved through the following technical solutions:

A kind of electronic pen digs, it is made up of shell (8) and the locating hole (3) that is used for fixing a position, and the pen that it also comprises power circuit (1) that power is provided, be used to dig pen digs bistrique (2), is used for driving a drive circuit (4) and the power switch (5) that pen digs bistrique (2).

In technique scheme, described a kind of electronic pen digs, and the front end that described pen digs bistrique (2) is positioned at the front end of locating hole (3).

In technique scheme, described a kind of electronic pen digs, and described power switch (5) is positioned at locating hole (3) inboard that is used for fixing a position.

In technique scheme, described a kind of electronic pen digs, and described power switch (5) is made up of two metal contacts.

In technique scheme, described a kind of electronic pen digs, and described shell (8) is gone up also has a square hole (6), and square hole has on (6)-individual openable lid (7), and the position of square hole (6) is corresponding with the position that pen digs bistrique (2).

Because the utility model adopted electric power to drive as power, and adopted pen to dig bistrique to sharpen a pencil, so can make things convenient for, carry out uniformly work with the mode of grinding.Power switch is positioned at the locating hole inboard, and therefore the pressure owing to pencil itself is connected contact switches after pencil inserts locating hole, realizes the function of cutting nib automatically.Powder behind the intact nib of grinding can be poured out from the square hole on the shell.Realized so fully sharpening a pencil easily and fast and automatically.

Below in conjunction with accompanying drawing the utility model is done further embodiment explanation:

Shown in Figure 1 is structural representation of the present utility model;

As shown in Figure 1, the utility model digs bistrique 2, drive circuit 4 and power switch 5 by shell 8, locating hole 3, power circuit 1, pen to be formed, and all is positioned at the inside of the utility model shell 8.The front end of locating hole 3 has a tapered openings near the inboard, and the front end that pen digs bistrique 2 is positioned at the aperture of the front end of locating

hole

3, and 2 the side that pen digs bistrique is positioned at the inboard of locating hole 3.Power switch 5 is positioned at locating hole 3 inboards, is made up of two metal contacts.A square hole 6 is arranged on the shell 8, an openable lid 7 is arranged on the square hole 6, the position of square hole 6 is corresponding with the position that pen digs bistrique 2.What present embodiment adopted is daily used dry cell.During use pencil is inserted in the locating hole, contact on the power switch 5 of the locating hole of pencil extruding at this moment 3 inboards, make power switch 5 closures, power connection, drive circuit 4 is started working, drive pen and dig bistrique 2 rotations, pen digs bistrique 2 and is taper, is made by harder material, because pen digs in the aperture of front end that bistrique 2 stretches into locating hole 3, and the inboard that has a side to be positioned at locating hole 3 contacts with the pencil nib, by rotating the pencil nib sharpening that stretches into.More even for grinding can rotate pencil that several locating hole 3 inboard contacts lose pressure down gently, because elasticity disconnects power switch 5, pen digs bistrique 2 and drive circuit 4 quits work.At this moment the lid on the square hole on the shell 867 can be opened, the powder after the grinding is poured out.

Claims
