As shown in fig. 1 and 2, according to an embodiment of the present invention, there is provided a knock type pen including a tubular barrel 10, a cartridge 13, a telescopic control mechanism, a clip 30 in a form of a thin and long plate, and an elastic member 50. The side wall of the tubular pen holder 10 is provided with a long hole 11 extending along the axial direction of the tubular pen holder 10, and the length of the long hole 11 can be two thirds of the length of the tubular pen holder 10. The cartridge 13 is provided in the tubular barrel 10 and can move forward and backward in the tubular barrel 10. The telescopic control mechanism is arranged on the tubular penholder 10 and connected with the rear end part of the refill 13.

The pen clip 30 is disposed on the side of the tubular pen holder 10, the length of the pen clip 30 is much greater than the width and greater than the thickness, the length extends along the axial direction of the tubular pen holder 10, the pen clip 30 is connected to the telescopic control mechanism through the long hole 11 in a first dovetail groove structure, and the telescopic control mechanism drives the pen point of the pen core 13 to freely extend from the front end of the tubular pen holder 10 by pressing the pen clip 30 forward. The elastic member 50 is configured to apply a force in a backward direction to the cartridge 13, the elastic member 50 is fitted around the outer circumference of the cartridge 13, and the elastic member 50 is fitted into the tubular barrel 10 in such a manner that the nib 12 is screwed into the front end of the tubular barrel 10. Wherein, the pen core 13 can be fixedly connected to the telescopic control mechanism through a buckle structure.

In an embodiment of the present invention, the expansion and contraction control mechanism may include a lifting member 42 as shown in fig. 5 and a rotating member 41 as shown in fig. 6 to realize the pressing of the present invention.

The rotary member 41 is formed with a stepped portion 41a having an upper end inserted into the link 43 and rotatably coupled to an inner end of the link 43, a telescopic operation protrusion 41b formed at both sides of a central portion of the rotary member 41, and a rotary guide protrusion 41c formed at a lower portion at an equal interval. Wherein, the connecting piece 43 is arranged in the tubular barrel 10 and is fixedly connected to the rear part of the tubular barrel 10 through the top cap 60.

The elevation member 42 is formed in a pipe shape and rotatably inserted into the rotation member 41, and fixing protrusions 42a are formed at both sides of an upper portion inside the elevation member 42. A fixing groove 42d is formed on an upper end inclined surface of the fixing protrusion 42a to be inserted and locked into a lower side corner portion of the telescopic operation protrusion, upper and lower inclined surfaces of the fixing protrusion 42a are formed in opposite directions, the upper end inclined surface is formed to be in surface contact with a lower end inclined surface of the telescopic operation protrusion 41b, and the lower end inclined surface is formed to be in surface contact with an upper end inclined surface of the rotation guide protrusion 41 c.

Specifically, when the pen clip 30 having a slender sheet shape and configured to be operable on the side surface of the tubular barrel 10 is repeatedly lowered while the tubular barrel 10 is held, the pen core 13 is extended or retracted.

Further, referring to fig. 8 and 9 together, when the knock type pen is used, if it is necessary to protrude the pen point of the pen core 13, the pen clip 30 is operated to descend, and at this time, the ascending and descending member 42 constituting the expansion and contraction control mechanism descends together with the pen clip 30, and the fixing protrusion 42a formed inside comes into contact with the locking rotation guide protrusion 41c-1 of the rotation protrusion 41c of the rotation member 41 to descend, and the locking rotation guide protrusion 41c-1 is pushed to one side to rotate the rotation member 41 by a predetermined angle, so that the descending fixing protrusion 42a moves to the space D where the locking rotation protrusion 41b can be locked, and the pen point of the pen core 13 descends and protrudes together.

When the lowered pen core 30 is released, the clip 30 is lifted by the elasticity of the elastic member 50, and the lifting member 42 coupled to the expansion control mechanism 40 is lifted together.

When the elevation member 42 is raised, the upper end inclined surface of the fixing projection 42a and the lower end inclined surface of the extension/contraction operation projection 41b are raised while being in contact with each other, and at this time, the extension/contraction operation projection 41b is pushed open and the rotation member 41 is rotated by a predetermined angle, and the lower end corner portion of the extension/contraction operation projection 41b is inserted into the fixing groove 42d of the elevation member 42 fixed to the raising, whereby the raising is not continued and the pen tip of the projecting pen core 13 is not retracted.

Meanwhile, the fixing groove 42d formed at the upper end of the fixing protrusion 42a is located at a position not passing through the corner portion of the telescopic operation protrusion 41b by the difference of the degree of the interval a between the telescopic operation protrusion 41b and the rotation guide protrusion 41c-2, so that the corner portion of the telescopic operation protrusion 41b is inserted into the fixing groove 42d of the ascending and descending operation member 42, and is not continuously ascended in a state where the cartridge 13 is protruded, and the cartridge 13 can maintain the protruded state.

When it is necessary to retract the pen tip of the protruding pen core 13, the clip 30 is lowered again, and at this time, the lower end inclined surface of the fixing protrusion 42a formed in the elevation member 42 comes into contact with the upper inclined surface of the rotation releasing guide protrusion 41c-2 of the rotation protrusion 41c to complete the lowering, and at this time, the lowered fixing protrusion 42a pushes the rotation releasing guide protrusion 41c-2 open and the rotation member 41 rotates, so that the fixing protrusion 42a is positioned in the space E between the rotation locking guide protrusion 41c-1 and the rotation releasing guide protrusion 41c-2, which can retract the protruding pen core 13.

When the clip 30 is released from the above state, the clip 30 is lifted by the repulsive force of the elastic member 50, and the elevation member 42 coupled to the expansion and contraction control mechanism 40 is lifted, and the upper inclined surface of the fixing protrusion 42a of the elevation member 42 is brought into contact with the lower inclined surface of the expansion and contraction operation protrusion 41b to complete the lifting, so that the rotation member 41 is rotated by the lifting force of the expansion and contraction operation protrusion 41b, and the fixing protrusion 42a is positioned between the two expansion and contraction operation protrusions 41b, and the pen point of the pen core 13 completes the retraction operation.

At this time, the fixing groove 42d of the fixing protrusion 42a, which is lowered between the rotation guide protrusions 41c, is lifted, and is positioned at the inclined surface apart from the corner portion of the telescopic operation protrusion 41b, thereby completing the lifting operation.

Further, the distance B between the retractable operation protrusion 41B and the rotation release guide protrusion 41C-2 is formed to be narrower than the length C of the fixing protrusion 42a, so that even if the fixing protrusion 42a is shaken by an external impact or the like when it is lowered toward the space D for the retraction of the pen core 13, the fixing protrusion 42a is longer than the distance B and the lower end is locked to the rotation release guide protrusion 41C-2, and is stably lowered to the space D and then raised to the retractable operation protrusion 41B, so that the protruding pen core 13 can be maintained in a protruding state, and the locking operation can be completed.
