Abstract

PURPOSE: A sharp pencil and a mechanical pencil container are provided to save time by putting a mechanical pencil into the sharp pencil without separately bring out the mechanical pencil to outside. CONSTITUTION: The projected entrance of a mechanical pencil container which includes mechanical pencils is connected to the concave lid(1) of a sharp pencil. A button(2) which is attached to the side of the mechanical pencil and the sharp pencil is pressed at the same time. The mechanical pencil container is located in the lower part of the sharp pencil. The mechanical pencil passes through a hole of the inside of the mechanical pencil container. The mechanical pencil passes through the projected entrance of the mechanical pencil container and passes through the concave lid of the sharp pencil. The mechanical pencil is inserted in the inner pipe of the sharp pencil. The button is returned to original position by the elastic force of a spring.

Description

Mechanical pencil and case of mechanical pencil's lead which is easy to put lead in a mechanical pencil}

The present invention relates to a mechanical pencil containing a sharp pencil and a sharp core used therein among writing instruments.

In the prior art, the sharp shim in the sharp shim barrel is taken out of the sharp shim barrel, and the sharp shim is filled by opening the cap of the sharp pencil and inserting the taken out shim.

The prior art has the hassle of removing the sharp shim from the sharp shim barrel and opening the sharp pencil lid again when filling the sharp shim in the sharp pencil. It can also break when the sharps are pulled out. The present invention is to reduce the inconvenience and sharpen the risk of breaking the sharp seam.

Attach the protruding opening to the outer part of the sharp shim from the sharp shim barrel, and attach the concave and perforated lid to the sharp pencil to enter the protruding opening of the sharp shim barrel. After attaching a button that can be pushed to each of the sharp shim passing sharp pencils, and pressing this button, a block is opened inside the sharp shim passing sharp pencil so that the sharp shim cannot escape, and when the convex part of the sharp shim and the concave part of the sharp pencil are connected, Sharp can pass through at once and use gravity to drop it to charge the Sharp Pencil. Each button is connected to an internal spring, which is designed to close the lid on its own when the button is released.

Unlike the prior art, it is possible to save time and reduce the hassle in that the sharp shim can be charged in the pencil without removing the sharp shim separately. It also eliminates the risk of sharpness coming out and breaking.

Figure 2 is a front view of a sharp seam barrel with a protruding inlet

A button attached to the side of the sharp shim passing mechanical pencil after connecting the protruding opening of the sharp shim container containing the sharp shim (1 in Fig. 2) and the concave lid of the sharp pencil (1 in Fig. 1) (2 in Fig. 1, drawing) 2) 2) at the same time, while pressing and tilting the sharp shim barrel with the sharp pencil down, the sharp shim passes through the perforated plate (3 in Fig. 2) inside the sharp shim barrel and the protruding inlet of the sharp shim barrel (Fig. After exiting 1), it passes through the concave and centered lid of the pencil (1 in Fig. 2) and passes through the disc (3 in Fig. 1) with a hole inside the mechanical pencil to enter the tube inside the pencil. It is filled inside the sharp pencil. When the button is released, the button is pushed back to its original position by the spring force inside the sharp pencil and the sharp shim barrel. In the pencil, the inner spring is connected to a small plate (4 in Fig. 1) and a button (2 in Fig. 1) is connected to the opposite side. In addition, in the sharp core cylinder, an internal spring (4 in Fig. 2) is connected to a perforated plate (3 in Fig. 2), and a button (2 in Fig. 2) is connected to the opposite side thereof. This causes the plate drilled in the sharps barrel (3 in Figure 2) to move to the side, preventing the sharps from escaping outward. In the sharp pencil, a small plate (4 in Fig. 1) attached above or below a perforated plate (3 in Fig. 1) moves to the side to prevent the sharp core from coming out.
