Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 2 and 3, the needle tube pen with the pen point and the cotton core convenient to replace is characterized by comprising a pen point 7 and a cotton core 6, wherein one end of the pen point 7 is detachably connected with a pen nozzle 2, the inner side of the pen nozzle 2 far away from one end of the pen point 7 is detachably connected with a cotton core sleeve 5, and the outer side of the pen nozzle is connected with a pen holder 1; the outer side of the cotton core sleeve 5 is sleeved with the pen holder 1, and the inner side of the cotton core sleeve is provided with a cotton core 6; a detachable tail plug 4 is arranged at one end of the cotton core sleeve 5, which is far away from the pen nozzle 2;

as shown in fig. 2, the pen tip 7 comprises a pen tip sleeve 70 and a pen core 72, wherein the outer side of the pen tip sleeve 70 is provided with a groove 702, and the upper end is provided with a coaxial guide column 701; the guide column 701 is detachably connected with the pen nozzle 2; a pen core 72 which coaxially penetrates through the guide column 701 is arranged in the middle of the pen point sleeve 70;

as shown in fig. 3, a tail plug groove 42 is arranged on the outer side of the upper end of the tail plug 4, and a coaxial fixing column 43 is arranged at the lower end; the fixed column 43 is in interference fit with the cotton core sleeve 5;

the pen core 72 is used for guiding out the ink in the pen holder 1 and transferring the ink to a written medium; the groove 702 may facilitate the user to remove the nib 7 from the nib 2 by using a nail cover or other tool;

the tail plug groove 42 can facilitate the user to take the cotton core sleeve 5 out of the pen nozzle 2 and the pen holder 1 by hand or other tools.

In the embodiment, the utility model forms a reasonable structure for disassembling the pen point and the cotton core by arranging the groove 702 and the tail plug groove 42 on the pen point 7 and the tail plug 4 respectively and matching with the cotton core sleeve 5; when the original pen point 7 is damaged and needs to be replaced, the pen cap 4 is taken out, the groove 702 of the pen point 7 is pressed by hands, the thumb nail extends into the groove 702, the pen point 7 is forcibly detached, and therefore the original damaged pen point 1 is detached from the pen nozzle 2, and the detachment of the pen point 3 is completed; then, the new pen tip 7 is forcibly pressed and attached to the pen nib 2, and the attachment of the pen tip 7 is completed.

When the original cotton core 6 needs to be replaced, the tail plug 4 is grabbed by a hand, fingers are attached to the tail plug groove 42, the tail plug 4 is forcibly detached, the tail plug 4 drives the cotton core sleeve 5 to move, so that the tail plug 4 and the cotton core sleeve 5 are integrally detached, then the tail plug 4 is detached from the cotton core sleeve 5, the original cotton core 6 can be taken out, and the detachment of the cotton core 6 is completed; then, a new cotton core 6 is placed in the cotton core sleeve 5, the tail plug 4 is pressed forcibly to enable the tail plug 4 to be tightly connected with the cotton core sleeve 5, then the tail plug 4 is pressed forcibly to install the cotton core sleeve 5 in the penholder 1, and installation of the cotton core 6 is completed.

Through this structure, under the condition with the help of not external instrument, can be convenient, swift completion nib, the replacement of cotton core, reach circulated use effect, energy-concerving and environment-protective, convenient and fast.
