Abstract

A multi-functional mechanical pencil is provided to supply leads without blocking up an entry path of a lead fixing unit when plural leads are collected together in the lead fixing unit. A multi-functional mechanical pencil comprises: a lead fixing unit(100); a lead supply chamber(200) for storing leads inside and having a lead insert hole formed at the lateral side to receive the lead from the outside, wherein the opened lower end of the lead supply chamber is connected to the lead fixing unit; and a lead supplementing unit for surrounding the lateral side of the lead supply chamber, rotating for the lead supply chamber, and including plural partitions(310) aligned at the inside in a longitudinal direction of the lead supply chamber.

Description

Multifunctional sharp writing implements {MECHANICAL PENCIL WITH PARTITIONED LEADS ROOM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical pencil having a plurality of mechanical pencil storage chambers, and more particularly, to a mechanical pencil capable of selectively using the mechanical pencils stored in each mechanical pencil storage chamber by a user's operation. A mechanical pencil is a writing tool made by inserting a thin shim and turning or pressing the tip of the shaft to push the nib out little by little.

It is an exploded perspective view which shows an example of the conventional mechanical pencil. As shown in FIG. 1, there is a sharp shim fixing part 10 for fixing a shim used in the mechanical pencil, and a sharp shim supply chamber 20 connected to the sharp shim fixing part 10 so as to supply the sharp shim to the sharp shim fixing part. have. The sharp shim supply chamber 20 is configured to store the sharp shims therein. The sharp shims in the sharp shim supply chamber 20 are loaded into the sharp shim fixing part 10 one by one by gravity and a user's pressing or rotating operation.

The sharp shim fixing part 10 pushes the loaded sharp shim little by little by the user's pressing or rotation operation, and newly fixes the position of the sharp shim with respect to the sharp pencil.

The sharp pencil body 30 is coupled to the circumference of the sharp shim supply chamber 20 so that the user can comfortably hold the mechanical pencil, and the upper end of the sharp shim supply chamber 20 prevents the sharp shim stored in the sharp shim supply chamber 20 from escaping. Faucet 50 is coupled to facilitate the user's pressing operation.

The conventional mechanical pencil has the following problems.

In order to eliminate the inconvenience of carrying the sharp shim container separately or the discomfort of frequently changing the sharp shim in the sharp shim supply chamber 20, if too many sharp shims are put in the sharp shim supply chamber 20, the sharp shim fixing portion (only one sharp shim should be loaded) The sharpness is very often concentrated in 10). Since the sharp shim fixing part 10 is designed to be loaded with only one sharp shim, when two or more sharp shims enter the driveway of the sharp shim fixing part 10, the operation of the mechanical pencil stops. It is very cumbersome and cumbersome for the user to disassemble the sharp shim fixing part 10 to pierce the access road of the blocked sharp shim fixing part 10 to solve such a failure. In addition, frequent failures take valuable time and effort from the user.

The present invention is to solve the problems of the mechanical pencil as described above, the object of providing a mechanical pencil without a large number of sharp cores are concentrated in the sharp core fixing section 100, while a sufficient amount of sharp shim is stored. It is done.

According to the present invention, while a sufficient amount of sharp shim is stored, too many sharp shims are concentrated in the sharp shim government 100.

A mechanical pencil is provided without a problem.

According to one embodiment of the present invention for achieving the object as described above, the sharp shim fixing portion is fixed sharp; A sharp core supply chamber having a shape capable of storing sharp cores therein, and having an open lower end connected to the sharp core fixing unit, and having a sharp core inlet hole formed at a side thereof from which the sharp cores can be inserted; And a shape surrounding the side of the sharp core supply chamber and formed to be rotatable with respect to the sharp core supply chamber, the inner surface of which comprises a sharp core filler including a plurality of partitions formed in a longitudinal direction of the sharp core supply chamber. do.

1 is an exploded perspective view showing an example of a conventional mechanical pencil;

2 is an exploded perspective view showing a mechanical pencil according to an embodiment of the present invention.

3 is a cross-sectional view of the mechanical pencil according to one embodiment of the present invention cut in a direction perpendicular to the longitudinal direction thereof.
