[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other in the absence of conflict, and the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0023] See also Figure 1-6 The present embodiment describes a replaceable ink cartridge gel pen, which includes a pen body and an ink cartridge 5. The pen body includes a front rod 10 and a rear rod 9. The rear rod 9 is connected to the rear end of the front rod 10. The front end of the front rod 10 is provided with a nib 11. An ink passage cavity is provided in the front rod 10. The front end of the ink passage cavity is connected to the nib 11. The rear end of the ink passage cavity is connected to an insert 1. The ink cartridge 5 is plugged into the insert 1 and is connected to the ink passage cavity through the insert 1. In this embodiment, the roller is connected to the roller. The ballpoint pen tip 11 is arranged on the front shaft 10 of the pen and is connected to the ink cavity in the front shaft 10 of the pen, and an insert 1 that is plugged into and cooperates with the ink bag 5 is provided at the tail end of the ink cavity. When the ink in the ink bag 5 is used up, the ink bag 5 only needs to be pulled out, ink is added through the interface 4, and then the insert 1 of the front shaft 10 of the pen is plugged in again to complete the filling of the gel pen. This reduces the need to throw away the used gel pen refill when replacing the traditional gel pen refill, reduces unnecessary waste, and saves the cost of using the gel pen and replacing the refill.

[0024] In this embodiment, one end of the ink sac 5 is provided with an interface 4 that matches the plug-in 1 . The interface 4 is used for connecting the ink sac 5 with the plug-in 1 and for adding ink to the ink sac 5 .

[0025] In this embodiment, the outer side of the tail end of the front rod 10 of the pen is provided with an external thread 2, and the inner side of the front end of the rear rod 9 of the pen is provided with an internal thread 3 that matches the external thread 2. The front rod 10 of the pen is screwed to the internal thread 3 of the rear rod 9 of the pen through the external thread 2. During normal writing and use, there is no need to tighten the thread. When the lighting function of the pen needs to be used, just tighten the thread.

[0026] The pen tip 11 described in this embodiment is a ball pen tip, and a ball is provided at the tip of the pen tip 11 for moving ink when writing.

[0027] In this embodiment, a light-emitting diode 7 is provided at the tail end of the rear rod 9 of the pen, and a battery 6 is provided between the light-emitting diode 7 and the tail end of the ink sac 5. The upper and lower ends of the battery 6 are respectively in contact with the light-emitting diode 7 and the tail end of the ink sac 5. A light-emitting diode 7 is provided at the tail end of the rear rod 9 of the pen. When the thread between the front rod 10 of the pen and the rear rod 9 of the pen is tightened, the tail end of the ink sac 5 is tightly against the bottom of the battery 6. At this time, the top of the battery 6 is connected to the light-emitting diode 7, and the light-emitting diode 7 emits light and plays a lighting role. When the lighting function is not needed, just loosen the thread between the front rod 10 and the rear rod 9 of the pen. At this time, the ink sac 5 is separated from the battery 6, and the battery 6 is thus separated from the light-emitting diode 7, and the light-emitting diode 7 stops emitting light.

[0028] In this embodiment, a first transparent window 8 is provided at the tail end of the pen rear shaft 9 , and the light emitted by the light emitting diode 7 is illuminated through the first transparent window 8 .
