Description

Penholder Holder Usable A Stubby Pencil}

The present invention relates to a pencil holder mechanism that can be used conveniently by extending the length of a mongdang pencil, which is difficult to sharpen and difficult to write in the pencil sharpener of the present invention. It is possible to extend the length of the shortened Mongdang pencil by inserting and connecting it so that the shortened Mongdang pencil can be cut and put into the pencil sharpener without any difficulty, and it is related to a pencil holder mechanism that can be used for easy writing. .

Usually, pencils made of wood consume pencil cores (graphite) of the pencil body when used to some extent, and they are frequently used to sharpen the pencil. In most cases, the pencil blade is inserted into the cutting hole of the pencil sharpener to rotate the handle to rotate the cutting edge of the pencil sharpener. The wooden pencil body can be shaved by a certain length.

By the way, the pencil sharpened from time to time is shorter and more comfortable to hold the writing is not only difficult to write, but also the mongdang pencil that can not only reduce the writing and writing speed, at this time, in order to use the mongdang pencil without discarding the ballpoint pen body or other Is inserted into the rear end of the pencil pod to extend the length is utilized.

On the other hand, the pod means such as ballpoint pens, which are used as an extension of the length of the Mongdang pencil, can be used to easily write the mongdan pencil shortened without any difficulty in gripping operation. There is also a disadvantage that is not beautiful.

The present invention was developed to solve all the disadvantages of the pencil pods (or pencil holders) introduced so far, not only can be easily used by extending the length of the mongdang pencil shortened to be difficult to sharpen into the pencil sharpener It can be easily connected with the same size as the outer diameter of the pencil body, so that the shortened pencil length of the Mongdang pencil can be easily extended while being inserted into the cutting hole of the pencil sharpener without structural difficulties. It is an object of the present invention to provide a pencil holder mechanism that can use the Mongdang pencil to improve the writing feeling by increasing the length of the pod by the length of the mongdang pencil which becomes shorter afterwards.

Pencil holder mechanism that can use the mongdang pencil of the present invention for achieving the above object is to be screwed with respect to the pencil body and spiral pencil protruding to the center of the rear end to be screwed together It comprises a cylinder 1 with a nut-shaped spiral projection at one side center, and a cylinder 2 with a pencil sharpener capable of screwing the cylinder 1 and making a rear end of the pencil body at the rear end with a spiral projection. The product is configured such that the entire outer diameter of the pencil holder mechanism maintains the same diameter as the outer diameter of the pencil body.

In particular, the cylinder 1 and the cylinder 2 can be overlapped to adjust the total length of the pencil holder mechanism, the screw body of the pencil body and the cylinder 1, the coupling of the screw when the cylinder 1 and the cylinder 2 of the coupling It is characterized in that the play is kept to a minimum and the coupling state is maintained.

As described above, the pencil holder mechanism that can use the mongdang pencil of the present invention can be clipped by inserting into the pencil sharpener cutting hole while maintaining the outer diameter of the mongdang pencil, the pencil holder mechanism and the pencil body to be screwed It is equipped with a pencil sharpener, and the length can be adjusted even after inserting the pencil holder mechanism. It can be used to adjust the length of the pencil holder mechanism according to the length of the pencil. It provides the effect of putting the pencil into the sharpener as well as the handwriting without any inconvenience.

1 is a pencil mechanism holder structure of the state can be used by screwing the mongdang pencil and the entire length
Figure 2 is a perspective view of the screwed state of the mongdang pencil and cylinder 1, cylinder 1 and cylinder 2, respectively

Or less, on the basis of the drawings of the preferred embodiment attached to the configuration and operation of the pencil holder mechanism that can use the mongdang pencil of the present invention will be described in detail. In addition, the following embodiment is a preferred embodiment for easily conveying the membership of the present invention can be applied to a variety of applications in the technical scope of the present invention is a matter of course.

Although the length of the main body of the pencil is 17cm before use, the length of the Mongdang pencil that can be held by students in the lower grades of the elementary school is usually about 6cm. In fact, since the pencil length which can actually be used is only half of the pencil body before use, it will be a great loss if you do not use the mongdang pencil.

In particular, in the case of shortened Mongdang pencil because most pencils are cut using a pencil sharpener, it is necessary to extend a pencil length of the pencil body by connecting a separate pencil pod without any problem, and the pencil holder mechanism which can use the Mongdang pencil of the present invention. Of course, the configuration is to simply connect the pencil pod of the same diameter as the outer diameter of the pencil body to be inserted into the cutting hole of the pencil sharpener to cut without any difficulty.

1 is a pencil mechanism holder structure of the state can be used by screwing the mongdang pencil and the total length, Figure 2 is a perspective view of the screwed state of the mongdang pencil and the cylinder 1, cylinder 1 and cylinder 2, respectively.

As shown in the drawings, the pencil holder mechanism of the present invention is a nut-shaped spiral protrusion 21 is formed in one direction of the cylinder 1 (20) to be screwed with the mongdang pencil basically the mongdang pencil pencil holder The diameter remains constant even when combined with the instrument.

In particular, the nut-shaped spiral protrusion 21 is 1 ~ 5% in diameter decreases as it goes inside the pencil and pencil holder mechanism can prevent the baggy when screwing and maintain a firm coupling.

In addition, since the cylinder 1 (20) and the cylinder 2 (30) are overlapped by screwing, the overall length of the pencil holder mechanism is adjustable, and the loosening is prevented during writing and the entire length is maintained by minimizing the play when screwing. Can be.

On the other hand, the present invention is provided with a pencil sharpener to cut the rear end of the mondang pencil to be screwed to the second half of the cylinder 2 (30) can be used to be able to screw any pencil with the pencil holder mechanism without any special processing in advance.
