The present invention relates to a portable pencil sharpener, and more particularly to fixing a pencil

Pencil to the holder and one side of the body that is screwed to the holder

The present invention relates to a portable pencil sharpener that can be cut evenly.

Generally, pencils are writing instruments that can be written and erased.

The body is machined in length and diameter for grip and graphite in the center of the body

When inserting the pencil lead processed into the wood so that the pencil lead is exposed to the outside

I'm using it.

When cutting the pencil like this, a knife or pencil sharpener is used.

When you sharpen a pencil using, you may be injured by a knife due to carelessness.

Occurred when the pencil was sharpened, even though it was not injured.

There was a problem that the sawdust falls around and pollutes the environment. specification

In order to solve the problem as described above,

In some cases, a pencil sharpener with a knife attached to one side of the insertion hole may be used.

At this time, the power to rotate the pencil or pencil sharpener is not constant

There was a problem that the pencil lead is broken or the pencil is not evenly sharpened.

The present invention is invented to solve the above problems, the object is a pencil

In addition to preventing injury to the user when cutting the pencil, the pencil can be cut evenly.

In providing an alternative pencil sharpener.

Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

same.

The present invention is a protrusion formed on one side and the insert is coupled to the center pencil

A holder having a ball, and a coupling groove that is screwed with a protrusion formed in the holder

On one side of the outer circumference is formed a discharge hole through the center and the ship

The start was to include a fixed body of the knife.

In addition, the protrusion formed on the holder has a plurality of incision grooves 13 in the longitudinal direction.

It is done.

In addition, the protrusion formed in the holder when the pencil is coupled to the coupling groove formed in the body

The diameter of the projections is formed to be slightly larger than the diameter of the coupling groove so as to fix tightly

to be.

In addition, the inside of the insertion hole formed in the holder can be firmly fixed to the pencil

Is the fixed bushing. Additives showing the present invention having such features

A detailed description with reference to the accompanying drawings is as follows. 1 is a kite according to the present invention

Is an exploded perspective view showing a clipper, Figure 2 shows a pencil clipper according to the present invention

3 is a cross-sectional view showing a state of use of the pencil sharpener according to the present invention.

to be. As referred to herein the present invention inserts the pencil 30 is inserted

One side of the holder 10 is provided with a ball 12 is a protrusion 11 is formed protruding,

The outer peripheral surface of the protrusion 11 is provided with a screw portion. Meanwhile, the holder 10

Is coupled to the body 20, the coupling groove 21 is screwed to the protrusion 11 is a mold

The outer peripheral surface of the body 20 is formed and the discharge hole 22 penetrating through

Is formed and the discharge hole 22, the knife 23 is determined by the fastening member 24 as a medium

Summed up. And the hole when the body 20 and the holder 10 is screwed

The circumferential surface of the protrusion 11 is firmly fixed to secure the pencil 30 inserted into the girth 10.

A plurality of incision grooves 13 are formed at equal intervals and the outer diameter of the protrusion 11 is a coupling groove 21.

It is preferable to form slightly larger than the inner diameter of.

This is because when the protrusions 11 are combined, the protrusions 11 are centered and opened.

This is to more firmly fix the peel (30).

On the other hand, the insertion hole 12 formed in the holder 10 that the pencil 30 is slipping

It is preferable to insert the fixing bush 14 made of a rubber material to prevent it.

This is because the pencil 30 and the holder 10 rotate together when the pencil 30 is sharpened.

To do this. In addition, the outer peripheral surface of the holder and the body when holding by hand

Indentation grooves may be formed to prevent slippage. Configured in this way

Referring to the process of sharpening a pencil with a pencil sharpener of the present invention in detail.

First, the pencil 30 is inserted into the insertion hole 12 formed in the holder 10, the opening

The tip of the peel 30, that is, the cutting edge of the pencil 30, is inserted so as to protrude out of the protrusion 11

Stock up. The reason for this is that when the holder 10 is coupled to the body 20, it turns to the outside of the protrusion 11.

This is because the ejected portion is cut by the knife 23. The hole in this state

When the projection 11 formed in the (10) is screwed into the coupling groove 21 formed in the body 20

The pencil 30 inserted into the holder 10 is coupled to the body 20 together with the holder 10.

At this time, the pencil 30 protruding to the outside of the protrusion 11 formed in the holder 10 is

It is mowed by the knife 23. In addition, the outer diameter of the protrusion 11 is the coupling groove 21

Since it is formed larger than the inner diameter of the incision between the narrow groove 13

And thus the projection 11 is to securely hold the pencil 30

Will be. In addition, the fixing bush 14 is inserted into the insertion hole 12 of the holder 10.

Since the pencil 30 is to be prevented from slipping.

As such, when the holder 10 is coupled to the body 20, the pencil 30 and the knife 23 come into contact with each other.

The contact force is to act uniformly as the pencil 30 is constantly sharpened

Will.

As such, the present invention does not protrude to the outside of the pencil sharpener can protect the user from injury, of course, pencil

Since the contact force between the pencil and the knife is uniformly acted upon when cutting the pencil, it is possible to cut the pencil constantly.

It works.

Claims (1)

Protrusion 11 is formed on one side and the holder 10 is formed in the insertion hole 12 is coupled to the pencil 30 in the center, and formed in the holder Coupling groove 21 is formed is coupled to the protrusion and screw is formed and the discharge hole 22 is formed through the central portion on one side of the outer peripheral surface thereof The discharge hole 22 is a portable pencil sharpener, characterized in that it comprises a body 20, the knife 23 is fixed.
