The present invention relates to a writing instrument, and more specifically, it is easy to use by integrating a mechanical pencil and an eraser so that the necessary one can be used, and it is not only convenient to carry, but also minimizes the risk of loss.
It is about digested writing utensils.
In general, there are various kinds of writing instruments, including pencils and mechanical pencils, where pencils have to be sharpened when the core is worn out, so it is inconvenient to use them. Sharp shim is widely used because it is convenient to use compared to pencil.
In addition, if you use a mechanical pencil, if you accidentally take a mistake by hand, you can erase it with an eraser. A typical mechanical pencil has a small amount of eraser on its top, and if you make a mistake during writing,
I'm crying.
However, the eraser attached to the upper end of the mechanical pencil has a limit on the amount thereof, and after use, it is difficult to replace it, which requires a separate eraser. In this case, the mechanical pencil and eraser are provided separately for use.
There is a problem that it is cumbersome and inconvenient to find and use a mechanical pencil and eraser one by one. In addition, since the mechanical pencil and the eraser are stored in separate states, they are inconvenient to carry and have a high risk of loss.
Therefore, the present invention has been devised to solve the above-mentioned problems, and it is convenient to use and easy to carry by lowering the risk of loss by integrating a sharpener and an eraser so as to select a desired one as necessary. The purpose is to provide a writing instrument.
In order to achieve the above object, the present invention provides a body having a flow preventing device having two fixing holes in the lower part and the upper part of the inner side; A lower cap screwed to the lower portion of the body and having a sharp drawing hole and an eraser individual hole formed at a lower end thereof; One side of the flow stopper
An eraser private exit portion inserted into the hole and including a holder on which an eraser is mounted at an end thereof, and a spring on which an end of the holder and an eraser construction work are placed; Is inserted into the other fixing hole of the flow prevention port, and the core and the core is stored in the sharp core, coupled to the top of the core
Is formed on the lower end of the cover and the core barrel Sharp lead-out device for stepping out the sharp shim by pressing the cover, Sharp lead-out cap screwed to the end of the sharp lead extraction device, and Sharp end lead-out cap and sharp Soup that drawing work is put on
A sharp drawing part including a ring; An extension part screwed to the upper end of the body and having a locking step formed at an inner lower end thereof; Inserted into the upper end of the extension at a predetermined distance from the locking jaw and the insertion hole having a protrusion on the inner periphery, and the hook formed on the upper outer
An upper cap comprising; Inserted from the lower portion of the extension portion is placed inside the insertion portion of the upper cap, the groove formed on the outer periphery corresponding to the projection, the lower end and the receiving portion formed on the lower end and the engaging portion is caught on the engaging jaw of the extension portion Including bottom surface
It includes a rotary knob is formed to be inclined so as to project the sharp drawer or the eraser with the sharp drawer hole or the eraser of the lower cap at 180 ° intervals by pressing the top of the holder of the cover or eraser outlet of the sharp drawer portion during rotation. By
Provides writing utensils.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
