Abstract
Start the compass. The present invention includes: a first leg portion to which writing instruments are fixed; and a second leg portion hinged to the first leg portion, to which an awl shim is mounted; and a handle portion to rotate the first leg portion with respect to the second leg portion; It includes, wherein the space is formed in the second leg portion, the awl core is formed so as to protrude out through the insertion hole formed at the end of the second leg portion selectively from the inner space of the second leg portion by the pressing means, at least one When the compass is not used by the pressing means provided in the leg portion of the leg portion, the pricking phenomenon can be prevented by placing the awl core in the inner space of the leg portion.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compass, and more particularly, to a compass which prevents a puncture during use or storage.
The compass is usually used to draw a circle or arc while narrowing and widening two legs. Such a compass is equipped with a sharp awl shim at the end of at least one leg portion of the two leg portions, so that the other leg portion can be rotated based on this to draw a desired circle or arc. However, since the end of the awl seam is always exposed to the outside of the compass, various threats such as the user may be stuck in a sharp part during operation, or may injure others around due to the carelessness of the user. Is present.
It is a main object of the present invention to provide a compass in which a pressing means is provided in at least one leg portion to prevent the phenomenon of being stuck during use or storage.
Compass according to an aspect of the present invention,
A first leg portion is fixed writing instruments; And,
A second leg portion hinged to the first leg portion and to which an awl shim is mounted; and
And a handle part for rotating the first leg part with respect to the second leg part.
A space is formed inside the second leg portion,
The awl shim is formed to protrude outwardly through an insertion hole formed at an end of the second leg portion selectively from the inner space of the second leg portion by a pressing means.
In addition, the pressing means,
A core portion coupled to the awl core, the core portion lifting and lowering from an inner space of the second leg portion;
Elastic bias means provided at one end of the core portion to elastically support movement of the core portion; And
It is installed on the other end of the core portion, the push button for pressing the core; includes.
In addition, the core portion is located along the longitudinal direction of the second leg portion in the inner space of the second leg portion,
One end portion of the core portion is coupled to the awl shim protruding to the outside through the insertion hole of the second leg portion,
At the other end of the core portion, the push button is installed to press the core portion.
Furthermore, an annular protrusion is formed at the rear of the elastic bias means along the outer surface of the core portion.
The inner surface of the second leg portion corresponding to the protrusion is provided with a jaw portion in contact with the protrusion is supported.
Furthermore, the push button is
A pressing part which is exerted from the outside and moves up and down through a pressing hole formed at the other end of the second leg part; and,
A pressing part which is formed at an end of the pressing part and presses an end of the core part;
And a plurality of protrusions bent in an opposite direction from an end of the pressing portion and formed on a surface opposite to a surface facing the pressing portion.
The protrusions may be selectively fastened to a plurality of fastening holes respectively formed in the corresponding body part, or may be simultaneously fastened to one fastening hole when the pressing part is pressed.
In addition, the push button,
Pressing portion is applied from the outside, the receiving groove is formed in the inner space of the second leg portion is formed to receive the end of the core portion;
And a sliding part integrally extending from the pressing part and protruding to an outer surface of the body part through a sliding groove formed in the body part.
A locking jaw portion is formed below the sliding groove so that the sliding portion is caught when descending.
As described above, the compass of the present invention can be prevented from being stabbed by placing the awl shim in the inner space of the leg portion when the compass is not used by the pressing means provided in the at least one leg portion.
Secondly, as the awl shim is stored in the inner space in the leg portion, it prevents damage to a writing material or a storage material such as a bag in which the leg portion is stored.
Third, the operation method of the compass is simplified, it can be easily used without special training.
