To this end, according to the present invention, the sharp shim L received in the sharp shim pipe 30 is drawn out through the lower portion of the cap 80 according to the pressing of the knob 50 coupled to the upper portion of the writing tube 20. In this case, the sharp shim L is in contact with the sharp shim pipe 30 around the inner wall surface of the sharp shim pipe 30 so that the sharp shim L, which is accommodated even when static electricity is generated, may be easily separated from the sharp shim pipe 30. The prevention protrusion 31 is formed, and the support tube 60 is coupled to the inside of the sharp seam pipe 30 by a predetermined depth in one end of the sharp seam pipe 30 so that the sharp seam L is always accurately drawn out to a constant length. It characterized in that the locking jaw 32 is formed to be supported by the support tube 60.
Description
The present invention relates to a mechanical pencil that can be easily drawn out of the sharp seam, and more specifically, the sharp seam in the sharp seam pipe is formed by forming an anti-static protrusion so that the sharp seam can be in point contact around the inner wall surface of the sharp seam pipe in which the sharp seam is stored. The present invention relates to a mechanical pencil that can be easily pulled out of the sharp shim that does not stick to the inner wall of the sharp shim pipe due to static electricity, thereby improving convenience of use.
Generally, the pencil is configured so that the sharp shim comes out through the lower part of the cap when the knob is coupled to the upper part of the writing tube. The pencil does not need to be sharpened like a pencil. Is one of the widely used writing instruments.
In this case, if the knob fixed to the upper part of the writing tube is briefly pressed, the sharp shim will protrude through the lower part of the cap, and if the key is pressed and released, the sharp shim will automatically be inserted into the inside of the cap. This has been proposed.
However, the above-mentioned mechanical pencil sharpening of the sharp seam has a structure for automatically sharpening the sharp seam to the structure of the sharp pencil, which is composed of a conventional complex configuration, and the overall configuration is very complicated, which makes the assembly work difficult and increases the manufacturing cost. Closure occurred.
In addition, since a ring, which is a kind of part to automatically sharpen the sharp shim, is forcibly inserted into the inside of the cap, not only a closed part such as a failure rate increases during assembly, but also a failure occurs once the parts are joined. It was almost impossible to repair.
In addition, since the metal tube for accommodating the lower chuck of the sleeve containing the sharp shim is directly screwed to the metal cap and the synthetic resin writing tube is fixed by the screwed metal tube and the metal cap, not only the total number of components is increased. Most of the components are made of metal, there was a problem that is the main reason for increasing the price of the pencil.
In addition, according to the
As described above, the conventional

In addition, the
Therefore, in the related art, in order to prevent the static electricity of the
Accordingly, the present invention has been made in order to solve the above problems, the purpose of the first, by forming an antistatic protrusion around the inner wall surface of the sharp shim pipe, the sharp shim accommodated in the sharp shim pipe is in contact with the antistatic protrusion as a point Even if static electricity is generated in the sharp seam pipe, the sharp seam does not stick to the inner wall of the sharp seam pipe, so that the sharp seam can be smoothly drawn out, thereby maximizing convenience of use.
Second, since the anti-static protrusions are formed on the inner wall of the sharp core pipe, there is no need to use a separate chemical agent for preventing static electricity when manufacturing the sharp core pipe, thereby minimizing the convenience of work and manufacturing cost.
Third, by allowing the support tube and the chuck coupled to the sharp seam pipe to be coupled to a certain depth, the sharp seam is always smoothly drawn out to a certain length to maximize the productability.
Fourth, by forming a support protrusion to support the chuck in the interior of the coupler to which the chuck is coupled to produce a coupler with a minimum of work, withdrawal of sharp shim to maximize the convenience and work efficiency It is to provide an easy mechanical pencil.
The present invention for achieving the above object is in the mechanical pencil to be drawn out through the lower portion of the sharp seam pipe in the sharp seam pipe by pressing the knob coupled to the upper portion of the writing tube, around the inner wall surface of the sharp seam pipe An electrostatic prevention protrusion is formed so that the sharp shim can be easily separated from the sharp shim pipe even if the sharp shim is in point contact with the sharp shim pipe, and the sharp shim is easily separated from the sharp shim pipe. The present invention provides a mechanical pencil that can be easily drawn out of a sharp shim, characterized in that a locking jaw is formed to hold a support tube so that it can always be accurately drawn out to a certain length.
As such, the present invention forms an antistatic protrusion so that the outer surface of the sharp core can be in contact with the point around the inner wall of the sharp core pipe in which the sharp core is accommodated, so that even if static electricity is generated inside the sharp core pipe, the sharp core is formed on the inner wall of the sharp core pipe. It is easy to use and the sharp shim is drawn out to the cap smoothly without sticking.
In addition, the present invention has a locking jaw is formed so that the end of the support tube can be caught in the sharp shim pipe to be coupled to a certain depth, the sharp shim is always drawn out to a certain length through the chuck and accurate operation is made It is effective to maximize the performance and operability.
