[0051] The improvement point of the present scheme is that the pen body 1 adopts a structure different from the conventional setting, and the pen body 1 of the present scheme comprises a pen barrel 11 and a cartridge replacement part 12. The pen barrel 11 is internally provided with a drainage assembly composed of a regulator, a water guide core and other structures, and the pen head 3 is arranged at one end of the outer side of the pen barrel 11. The cartridge replacement part 12 is inserted at one end of the pen barrel 11 away from the pen head, and the cartridge replacement part 12 comprises an ink cartridge placement 121, and the ink cartridge placement 121 can be inserted with the commonly used ink cartridge.

[0052] The present scheme places the ink cartridge in the ink cartridge placement 121, and then completes the connection between the ink cartridge and the drainage assembly by adopting the connection form of the insertion connection of the cartridge replacement part 12 and the pen barrel 11, thereby avoiding the screwing action when replacing the ink cartridge and simplifying the operation of replacing the ink cartridge.

[0053] On the basis of the above-mentioned embodiment, referring to Figure 3 A card slot 111 is formed at one end of the pen barrel 11 away from the pen head 3, and the card slot 111 is a through slot, which can also be a through hole, and the specific shape is not limited.

[0054] In addition to the ink bag placing piece 121, the ink bag replacing part 12 is fixedly connected with a plug-in piece 122 at one end of the ink bag placing piece 121. The plug-in piece 122 is fixedly connected with a clamping block connecting plate 124. One end of the clamping block connecting plate 124 is fixedly connected with the plug-in piece 122, and the other end is fixedly provided with a clamping block 123. The clamping block connecting plate 124 is an elastic plate body, and the shape of the clamping block 123 corresponds to that of the clamping groove 111.

[0055] When the ink bag replacing part 12 and the pen barrel part 11 are plugged in, the plug-in piece 122 is located outside the pen barrel part 11, the ink bag placing piece 121 is located inside the pen barrel part 11, and the clamping block 123 is clamped into the clamping groove 111. The clamping block 123 is first inserted into the inside of the pen barrel part 11, at which time the clamping block connecting plate 124 is deformed. When the clamping block 123 reaches the position of the clamping groove 111, the clamping block 123 is clamped into the inside of the clamping groove 111, and the clamping block connecting plate 124 recovers from the deformation.

[0056] On the basis of the above-mentioned embodiments, referring to Figure 3 , the pen barrel part 11 further comprises a positioning groove 112. The positioning groove 112 is arranged at the end of the pen barrel part 11 away from the pen head, and one end of the positioning groove 112 is an open mouth. Two positioning grooves 112 are symmetrically arranged at the end of the pen barrel part 11, and the groove bodies are approximately "U"-shaped.

[0057] Referring to Figure 5 , the ink bag replacing part 12 further comprises a positioning piece 125 corresponding to the positioning groove 112. The positioning piece 125 is fixedly arranged on the plug-in piece 122, and the shape of the positioning piece 125 corresponds to that of the positioning groove 112. A holding structure capable of increasing friction is arranged on the outer side of the positioning piece 125. The holding structure only needs to increase the friction, such as a plurality of annular protrusions.

[0058] On the basis of the above-mentioned embodiments, the ink bag placing piece 121 comprises a placing groove 1211, an ink bag insertion opening 1212, and a taking structure 1213. The placing groove 1211 is an arc-shaped groove, and one side of the placing groove 1211 is an open mouth, which can place or take out the ink bag. The ink bag insertion opening 1212 is an opening arranged at one end of the placing groove 1211. The ink bag insertion opening 1212 is arranged corresponding to the plug-in end of the ink bag, and the ink bag insertion opening 1212 is mainly used to leave a position for connecting the ink bag and the water guide core. The taking structure 1213 is arranged on the placing groove 1211, and the ink bag can be taken out through the taking structure 1213. The taking structure 1213 only needs to facilitate the taking out of the ink bag. The following three implementation forms are given in the present solution, but the taking structure 1213 is not limited to the following three forms.

[0059] Form one, referring to Figure 4 , the taking structure 1213 is a through hole arranged in the groove bottom of the placing groove 1211. In form one, the taking structure 1213 is a round hole. When the ink bag needs to be taken out, the ink bag can be lifted up at the round hole by a finger.

[0060] Form 2, see Figure 5 and Figure 6 The retrieving structure 1213 includes a long, narrow channel formed at the bottom of the placement slot 1211. A ejector plate is installed inside the channel, with one side of the ejector plate fixedly connected to the bottom of the placement slot 1211. A gap is left between the periphery of the ejector plate and the inner wall of the long, narrow channel. The ejector plate is a long, narrow plate with an arc-shaped plate in the middle. When the ink cartridge needs to be removed, the ejector plate is pushed with a finger, and the ink cartridge is pushed out by the force of the ejector plate.

[0061] Form 3, see Figure 7 Unlike the previous two methods, Form 3 does not have a slotted structure at the bottom of the placement slot 1211. The retrieval structure 1213 is a notch at the ink cartridge insertion port 1212, which faces the opening of the placement slot. When retrieving the ink cartridge, simply pry it off by grasping the edge of the ink cartridge at the notch.

[0062] The above three forms are parallel implementation methods, which can be selected according to actual production capacity and demand. During production, the bag-changing part 12 is manufactured using a one-piece molding process.

[0063] Based on the above implementation plan, see Figure 8 This solution also improves upon the pen cap 2. The pen cap 2 includes a pen cap body 21, a display hole 22, and a rotating component 23. The pen cap body 21 serves as a cover corresponding to the pen barrel 11. The pen cap body 21 can be conventionally designed, and an external mounting plate can be connected to it, allowing the pen cap body to be hung on pockets, notebooks, papers, etc. The display hole 22 is a through hole formed on the pen cap body 21. The shape of the display hole 22 can be adapted; the attached diagram shows a round hole, but it can be changed to an elliptical hole, a polygonal hole, an irregularly shaped hole, etc., as needed. The rotating component 23 is rotatably connected to the pen cap body 21, and the portion of the rotating component 23 located on the outer side of the pen cap body 21 has a screwing part; the portion of the rotating component 23 located inside the pen cap body 21 extends to the inner side of the display hole 22.

[0064] With this structure, various patterns or texts can be printed on the rotating part 23 at the position corresponding to the display hole 22. By simply rotating the rotating part 23, different content can be displayed in the display hole 22, increasing the entertainment value of the stationery and improving the mood when using the stationery.

[0065] Based on the above implementation scheme, a plug hole is provided at the end of the pen cap body 21 away from the pen body 1, and a number of teeth are distributed on the inner wall of the plug hole; the rotating part 23 is plugged into and rotatably connected to the plug hole, and the rotating part 23 is provided with a tooth 231, which corresponds to the teeth in the plug hole; the display hole 22 is opened at the end near the plug hole.
