2A and 2B are a perspective view and an exploded perspective view of a pencil including a clips for a writing implement according to an embodiment of the present invention.

Referring to FIGS. 2A and 2B, at least one second projecting portion 11, one end of which is engaged with the first projecting portion 21 and flows at a predetermined angle, and the other end is bent, (20) having a first protrusion (21) formed on an outer circumferential surface thereof and a coupling groove (23) connected to the inlet at a side end thereof, the cover (10) An elastic part 30 which is bent or bent in the same direction at both ends and is inserted between the insertion part 20 and the lid part 10 and is inserted into the engagement groove 23 by elasticity, A sharp mechanism portion 50 for receiving the sharp heart and pulling out the sharp point by one step of pressing; a body portion 70 in which the sharp mechanism portion 50 is accommodated; And a tip end stop 90 that engages with the shaper mechanism portion 50.

The lid 10 serves to open or close an inlet through which the sharpness received in the charging unit 20 is inserted. The lid 10 is folded at a predetermined angle and the second projection 11 is formed at the lower end. The second protruding portion 21 protrudes from the lid 10 at a predetermined height and is formed with a coupling structure (not shown) such as a recessed portion or a hole (not shown) And is coupled to the input unit 20 by a rotation shaft. That is, the lid unit 10 is coupled to the charging unit 20 and is located at the top of the pencil and at the side of the charging unit 20 to form a single clip-type lid.

The charging unit 20 is connected to the lid unit 10 at an upper portion and a side surface thereof and is connected to the sharp mechanical unit 50 at a lower portion thereof to transmit a sharp force inputted from the inlet to the sharp mechanical unit 50, The portion 10 is coupled to the clip structure.

The first projecting portion 21 is formed on the outer circumferential surface of the charging portion 20 and the second projection 11 of the lid portion 10 is coupled to the upper portion of the charging portion 20 so that the lid portion 10 is fixed .

The insertion portion 20 is connected to the sharp mechanism portion 50 through the shaper mechanism portion 50, thereby forming an inlet through which the sharp shaft is inserted.

The elastic part 30 is inserted between the lid part 10 and the insertion part 20 to continuously apply pressure to one end of the lid part 10, that is, the bent part in the direction of the insertion part 20 , So that the lid 10 keeps the inlet closed.

That is, the elastic portion 30 is bent when the lid portion 10 is pressed in the width direction and opens the inlet along the path that is deformed in the original state. When the lid portion 10 is not pressed, the elastic portion 30 is bent The entrance is closed according to the route restored to its original state.

According to the above-described structure, the lid unit 10 and the insertion unit 20 described above are combined with the elastic part 30 to form a lid for a single pencil, and the lid of the lid unit 10 When the end portion is pressed, the lid 10 is opened in accordance with the deformation of the elastic portion 30.

The sharp mechanism part 50 receives one or more of the sharp axes inserted through the input part 20 and pushes the received sharp axes toward the tip end 90 when pressure is generated at one end. The sharpening mechanism part 50 may be formed in a cylindrical shape such that the sharpening mechanism part 50 is accommodated in the body part 70 and the other end is threadedly engaged with the tip end stop 90. The cross- Do not.

The sharp mechanism 50 is coupled to the lower portion of the charging unit 20, and the rotation preventing bar 51 may be further formed on the outer circumferential surface of the shaft mechanism 50 in the longitudinal direction. The anti-rotation bar 51 prevents the left and right rotation about the central axis in the longitudinal direction. That is, since the sharp mechanism part 50 is inserted into the inside of the body part 70 and received therein, not only the sharp mechanism part 50 but also the insertion part 20 coupled thereto and the lid part 10 Thereby preventing unnecessary lateral rotation.

The other end of the shaper mechanism portion 50 is formed with a spring member 55 for discharging the drawn shaft received when the one end is pressed and a threaded portion 57 for engaging with the tip end 90 as a sharp mechanism .

Further, a protective pipe 60 may be further inserted between the shaper mechanism portion 50 and the body portion 70. The protection pipe 60 is formed to have a predetermined thickness so that the sharp mechanical part 50 can be protected from external impact when the mechanical pencil 100 is used and a pipe hole 61 through which the rotation prevention rod 51 penetrates is formed . The protective pipe 60 has a function of initializing damage of the shaper mechanism part 50 from external shocks when using the mechanical pencil.

Further, the sharp mechanism part 50 may be further formed with a latch 79 in contact with the upper part. Such a latch 79 provides convenience to the user when he or she uses the pencil 100, such as a pocket.
