The knock guide member 140 is coupled to the clip member 130 in a state in which a plurality of knock members 160 are movably accommodated in the knock box unit 170, and the knock guide member 140 is a clip member ( It is coupled to the inner surface of (130), the knock member 160 is coupled in the form of force-fitting to the clip member 130 to prevent separation or separation.

Accordingly, the knock member 160 and the knock guide member 140 can stably maintain a coupled state so as not to be separated from the clip member 130.

This means that even if the clip member 130 is separated from the case member 110 when the pen nibs 11 to 13 are replaced after the use of the pen nibs 11 to 13 accommodated in the case member 110 is completed, the clip member 130 ), it is possible to freely separate the clip member 130 from the knock guide member 140, the knock member 160, and the knock box unit 170 without any concern.

Accordingly, the user can easily separate the clip member 130 from the case member 110, and the pen nibs 11 to 13 to be replaced are replaced inside the case member 110.

Meanwhile, the user fastens the clip member 130, and the pressing protrusion 143 protruding from the bottom surface of the knock guide member 140 presses the three nibs 11-13.

That is, since the pressing protrusion 143 is formed to protrude from the bottom surface than the knocks 161 to 163 and is formed in the center of the intermediate body 141, the pressing protrusion 143 has three nibs (11 to 13) It is located in the center.

Accordingly, as the user fastens the clip member 130 to the case member 110, the clip member 130 is fastened with all three nibs 11 to 13 pressed.

That is, the clip member 130 and the knock member 160 rotate according to the fastening of the clip member 130, and these knock members 160 do not directly contact the pen nibs 11 to 13, but the pressing protrusion 143 The clip member 130 is fastened in a contacted state.

Accordingly, the user can easily fasten the clip member 130 without interference with the pen nibs 11 to 13.

Although the invention made by the present inventor has been described in detail according to the above embodiment, the invention is not limited to the above embodiment and can be changed in various ways without departing from the gist of the invention.
