[0068] Example 1, as Figures 1-7 As shown, this utility model provides a writing pen, comprising:

[0069] Pen barrel 1, one end of which forms an opening 11, and the side wall of the pen barrel 1 is provided with an installation port 12;

[0070] Pen refill 2, which is slidably disposed in the pen barrel 1;

[0071] A return spring 4 is disposed in the pen barrel 1 and configured to directly or indirectly apply a spring force to the pen core 2 in a direction away from the opening 11;

[0072] A rotary drive module 3 includes a rotary component 31 and a sliding component 32. A rotary drive part 311 is provided on the rotary component 31, and a sliding drive part 321 is provided on the sliding component 32. The rotary drive part 311 and the sliding drive part 321 are attached together.

[0073] The sliding component 32 is slidably disposed in the pen barrel 1, the sliding component 32 is connected to the pen core 2, and the rotating component 31 is rotatably disposed in the mounting port 12;

[0074] The rotating component 31 is configured to rotate in the mounting port 12 to push the sliding drive component 321 toward the opening 11 via the rotating drive component 311. The sliding component 32 is configured to simultaneously drive the pen refill 2 to slide toward the opening 11 while sliding toward the opening 11.

[0075] Specifically, a mounting opening 12 is provided on the side wall of the pen barrel 1. The mounting opening 12 on the side wall can accommodate the rotating component 31 in the rotation drive module 3, so that the rotating component 31 can rotate in the mounting opening 12. The pen refill 2 is located in the pen barrel 1 and can slide in the pen barrel 1. At the same time, the sliding component 32 in the rotation drive module 3 can also slide in the pen barrel 1. The sliding of the sliding component 32 drives the pen tip 21 of the pen refill 2 to extend out of the opening 11 to meet the writing requirements.

[0076] During use, the rotating component 31 and the sliding component 32 cooperate with the rotating drive part 311 and the sliding drive part 321, which are attached to each other. When the pen tip 21 of the pen tip 2 extends out of the opening 11, the rotating drive part 311 applies pressure to the sliding drive part 321 to push the sliding component 32 to slide, thereby converting the rotational motion of the rotating component 31 into the sliding motion of the sliding component 32.

[0077] During the process of the user driving the rotating component 31 to rotate, the rotating drive part 311 abuts against the sliding drive part 321 to drive the sliding component 32 to slide. The rotating drive part 311 and the sliding drive part 321 abut against each other externally, rather than using a guide groove, so that the rotating component 31 can push the sliding component 32 to slide more smoothly during the rotation, thereby improving the smoothness of use.

[0078] In addition, in order to enable the pen tip 2 to automatically reset, after rotating the rotating component 31 so that the sliding component 32 drives the pen tip 21 of the pen tip 2 to extend out of the opening 11, when the user rotates the rotating component 31 again, the rotation drive part 311 of the rotating component 31 will move away from the sliding drive part 321. At this time, under the action of the reset spring 4, the pen tip 2 will retract back into the pen barrel 1 by the elastic force of the reset spring 4 and drive the sliding component 32 to slide in the opposite direction, so that the sliding drive part 321 applies pressure to the rotating drive part 311, thereby realizing the smooth retraction of the pen tip 2.

[0079] In one embodiment of this application, the rotation drive part 311 protrudes from the inner surface of the rotation component 31, and the outer periphery of the rotation drive part 311 forms a rotation drive curved surface 312.

[0080] The sliding drive unit 321 is in contact with the rotary drive surface 312;

[0081] As the rotating component 31 rotates to drive the sliding component 32 to move toward the opening 11, the distance between the part of the sliding driving part 321 that contacts the rotating driving surface 312 and the rotation center line of the rotating component 31 gradually increases.

[0082] Specifically, the rotary drive part 311 protrudes from the inner surface of the rotating component 31 to meet the requirement of side contact with the sliding drive part 321 on the sliding component 32. The surface design of the rotary drive surface 312 formed by the rotary drive part 311 needs to ensure that, during the rotation of the rotating component 31, the rotary drive surface 312 can contact the sliding drive part 321, allowing the sliding component 32 to move towards the opening 11 of the pen barrel 1 as the rotating component 31 rotates.

[0083] Specifically, when the user rotates the rotating component 31 to extend the pen tip 21 for writing, the rotating drive surface 312 abuts against the sliding drive part 321. As the pen refill 2 moves, the distance between the contact point between the rotating drive surface 312 and the sliding drive part 321 and the rotation center line of the rotating component 31 gradually increases, so as to enable the pen tip 21 of the pen refill 2 to extend to the outside of the opening 11.

[0084] Conversely, when the user finishes writing and rotates the rotating component 31 again, the rotating drive surface 312 will tend to detach from the sliding drive part 321. Under the action of the return spring 4, the return spring 4 transmits the elastic force to the sliding component 32 through the pen core 2, so that the sliding drive part 321 always stays against the rotating drive surface 312.

[0085] Specifically, during the process of the user rotating the rotating component 31 to retract the pen tip 21, as the rotating component 31 rotates and the sliding component 32 moves away from the opening 11 under the action of the reset spring 4, the distance between the part of the sliding drive part 321 that contacts the rotating drive surface 312 and the rotation center line of the rotating component 31 gradually decreases.

[0086] For the specific surface structure of the rotary drive surface 312, a raised arc surface is generally adopted. This enables the sliding component 32 to slide by contacting and cooperating with the sliding drive part 321 through the rotary drive surface 312. At the same time, the raised arc surface can also smoothly drive the sliding component 32 to slide, thereby improving the smoothness of operation.

[0087] In addition, during the process of the pen tip 21 retracting back to the pen barrel 1 under the action of the return spring 4, the rotation drive surface 312 can better cooperate with the movement of the sliding drive part 321 by utilizing its smooth curved surface structure.

[0088] In one embodiment of this application, the portion of the sliding drive part 321 that contacts the rotating drive surface 312 is an arc-shaped surface.

[0089] Specifically, the sliding drive unit 321 is provided with an arc-shaped surface, which allows the sliding drive unit 321 to smoothly contact and cooperate with the rotating drive curved surface 312 and slide smoothly relative to it. This is more conducive to improving the smoothness of the sliding of the rotating component 31 driving the sliding component 32, thereby improving the user experience and reducing the occurrence of stuttering.

[0090] In one embodiment of this application, the sliding component 32 is a sleeve, and the sliding drive part 321 is formed on the wall of the sleeve;

[0091] The pen refill 2 is inserted into the sleeve.

[0092] Specifically, the sliding component 32 adopts a sleeve structure, which allows the pen refill 2 to be inserted into the sliding component 32 for quick assembly.

[0093] In addition, a sliding drive portion 321 is formed on the outer tube wall of the sliding member 32. The sliding drive portion 321 can make good contact with the rotation drive portion 311 formed on the inner surface of the rotating member 31, so that the sliding member 32 can be smoothly driven to slide by the rotating member 31.

[0094] In one embodiment of this application, a strip-shaped mounting hole 322 is provided on the tube wall of the sliding component 32. The strip-shaped mounting hole 322 includes a first opening segment 11 and a second opening segment 11, which are interconnected. The width of the first opening segment 11 is smaller than the width of the second opening segment 11.

[0095] The inner surface of the rotating component 31 is also provided with a connecting shaft 313, and a stop plate 314 is also provided on the connecting shaft 313. The connecting shaft 313 passes through the strip mounting hole 322 and is located in the first opening 11 segment. The width of the stop plate 314 is greater than the width of the first opening 11 segment, and the width of the stop plate 314 is less than the width of the second opening 11 segment.

[0096] Specifically, to improve assembly reliability and ensure good contact between the rotary drive unit 311 and the sliding drive unit 321, a stop plate 314 is provided on the rotating component 31 via the connecting shaft 313. During assembly, the stop plate 314 can be inserted into the strip mounting hole 322 through the second opening 11 section. Then, the stop plate 314 moves to the first opening 11 section, so that the stop plate 314 will not disengage from the strip mounting hole 322.

[0097] During use, the rotating component 31 is restricted by the stop plate 314 and connected to the sliding component 32 by the connecting shaft 313, thereby ensuring good contact and cooperation between the rotating drive unit 311 and the sliding drive unit 321, so that the rotating component 31 rotates and the sliding drive unit 321 drives the sliding component 32 to slide smoothly.

[0098] In one embodiment of this application, the surface of the stop plate 314 opposite to the pen refill 2 is concave, and the concave surface matches the outer wall contour of the pen refill 2.

[0099] Specifically, the stop plate 314 has a concave surface, which allows the stop plate 314 to fit more closely to the surface of the pen refill 2 during writing, thereby positioning and supporting the pen refill 2 within the pen barrel 1.

[0100] In one embodiment of this application, the tube wall of the sliding component 32 is formed with a recess, the recess forms a mounting surface, and the mounting surface is a plane;

[0101] The sliding drive part 321 is a protruding structure formed on the assembly surface, and the rotating drive part 311 is arranged on the outer side of the assembly surface.

[0102] Specifically, the sliding component 32 adopts a sleeve structure, and the outer surface of the tube wall is generally arc-shaped. In order to ensure good contact between the sliding drive part 321 and the rotary drive part 311, a mounting surface is formed on the outer tube wall of the sliding component 32, and a protruding sliding drive part 321 is formed on the mounting surface. In this way, after the rotary component 31 and the sliding component 32 are assembled together, the rotary drive part 311 of the rotary component 31 is attached to the mounting surface and can better fit against the sliding drive part 321.

[0103] In one embodiment of this application, the end of the rotary drive unit 311 away from the rotation center line of the rotary component 31 is provided with a first positioning notch 315;

[0104] When the pen tip 21 of the pen refill 2 extends outside the opening 11 and is in a writing state, the sliding drive part 321 is engaged in the first positioning notch 315.

[0105] Specifically, to ensure stable writing by keeping the pen tip 21 outside the pen barrel 1 after it extends beyond the pen body 1, the sliding drive part 321 engages with the first positioning notch 315 after the user rotates the rotating component 31 to extend the pen tip 21 beyond the pen barrel 1. This prevents the rotating component 31 from rotating without significant external force, and also restricts the movement of the sliding component 321 by cooperating with the first positioning notch 315, thus ensuring the pen tip 21 remains exposed during writing.

[0106] In another embodiment, the rotary drive unit 311 is provided with a second positioning notch 316 at the end adjacent to the rotation center line of the rotary component 31;

[0107] When the pen tip 21 of the pen refill 2 is retracted to its maximum position inside the pen barrel 1, the sliding drive part 321 is engaged in the second positioning notch 316.

[0108] Specifically, after the pen tip 21 retracts into the pen barrel 1, in order to position the retracted pen tip 21, the sliding drive part 321 is engaged in the second positioning notch 316.

[0109] In one embodiment of this application, the pen barrel 1 includes a first barrel 13 and a second barrel 14, the first barrel 13 and the second barrel 14 being detachably connected together;

[0110] The first rod 13 has the opening 11 formed thereon, and the second rod 14 has the mounting port 12 formed thereon.

[0111] Specifically, to facilitate the assembly of components, the pen barrel 1 adopts a split structure. The mounting ends of the first rod 13 and the second rod 14 can be connected together by a threaded connection. The free end of the first rod 13 forms an opening 11 to meet the requirements of pen tip 21 extension and retraction. The second rod 14 is provided with a mounting port 12 to meet the installation requirements of the rotating component 31. After the pen tip 2 is inserted into the sliding component 32, the sliding component 32 is inserted into the second rod 14. Then, the rotating component 31 is assembled into the mounting port 12 and connected to the sliding component 32 through the connecting shaft 313 and the stop plate 314. Finally, the first rod 13 is connected to the second rod 14.

[0112] The technical solution of this utility model has the following technical effects compared with the prior art: By providing an installation port 12 on the wall of the pen barrel 1 to meet the installation requirements of the rotary drive module 3, the rotating component 31 in the rotary drive module 3 can rotate in the installation port 12. During the rotation, the rotating component 31 drives the sliding component 32 to slide in the pen barrel 1 through the cooperation of the rotary drive part 311 and the sliding drive part 321. Thus, when the pen tip 21 of the pen refill 2 extends out of the opening 11, the rotating component 31 drives the sliding component 32 to slide, thereby driving the pen refill 2 to move outward from the pen barrel 1. Since the rotary drive part 311 and the sliding drive part 321 are attached together to convert the rotational motion into linear motion, the phenomenon of jamming that is easy to occur during use due to the use of polygonal slots is avoided, and the smoothness of use is good. In addition, the overall structure of the rotary drive module 3 is simple and the internal cooperation relationship is only achieved through the external contact between the rotary drive part 311 and the sliding drive part 321. The structure is relatively simple, the processing difficulty and assembly difficulty are small, and the overall structure of the writing pen is simplified and the smoothness of use is improved.

[0113] Example 2, as Figures 8-17 As shown, this application also provides a rotary writing pen, based on the above embodiment one, except that: an opening 11 is formed at one end of the pen barrel 1, and an installation port 12 is provided on the side wall of the pen barrel 1.

[0114] The rotary writing pen includes two sliding components 32, namely a first slider 33 and a second slider 34. The first slider 33 is provided with a first sliding sub-drive part 331, and the second slider 34 is provided with a second sliding sub-drive part 341. The second slider 34 is also provided with a functional part 35. The rotation drive part 311 is located between the first sliding sub-drive part 331 and the second sliding sub-drive part 341.

[0115] The first slider 33 is used to mount the pen refill 2, so that the pen tip 21 of the pen refill 2 can extend beyond the opening 11 of the pen barrel 1 for writing. The second slider 34 is provided with a functional component 35 as needed, and the functional component 35 can be configured as required. For example, the functional component 35 can be a decorative item, a heated erasable tip, or an eraser. Here, the specific physical form of the functional component 35 is not limited.

[0116] The rotating component 31 is rotatably disposed in the mounting port 12, and the first sliding member 33 and the second sliding member 34 are slidably disposed in the pen barrel 1.

[0117] The rotating component 31 is configured to rotate in the mounting port 12 to push the first sliding sub-drive unit 331 and the second sliding sub-drive unit 341 to slide via the rotating drive unit 311.

[0118] The first slider 33 is configured to slide in the direction of the opening 11 when the first slider drive part 331 is pushed, so as to drive the pen tip 21 of the pen refill 2 to extend out of the opening 11.

[0119] The second slider 34 is configured to slide in the direction away from the hole 11 when the second slider drive part 341 is pushed.

[0120] The sliding direction of the first slider 33 is opposite to that of the second slider 34. In this way, when the first slider 33 and the second slider 34 move in opposite directions toward the outside of the pen barrel 1, the pen tip 21 can be extended outside the pen barrel 1, and the functional component 35 is also simultaneously in use.

[0121] In one embodiment, a through hole 15 is formed at the other end of the pen barrel 1, and the second slider 34 is configured to slide in the direction of the through hole 15 when the second slider drive part 341 is pushed to drive the functional part 35 to extend out of the through hole 15.

[0122] Specifically, the other end of the pen barrel 1 is also an open structure, and the functional component 35 can extend through the through hole 15 to be in use. When the functional component 35 extends out of the pen barrel 1, it will perform its corresponding function.

[0123] Alternatively, the other end of the pen barrel 1 may have a transparent display section (not shown), and the second slider 34 may be configured to slide in the direction of the transparent display section when the second slider drive section 341 is pushed, thereby driving the functional component 35 to move to the transparent display section.

[0124] Specifically, a transparent display section is formed at the other end of the pen barrel 1. After the second slider 34 is pushed towards the transparent display section by the rotating component, the functional component 35 is displayed through the transparent display section. At this time, the functional component can be used as decoration.

[0125] It extends to the outside of the pen barrel 1 to enhance the functionality of the writing pen.

[0126] In addition, to meet the reset requirements, the rotary writing pen includes two reset springs 4, namely the first spring 41 and the second spring 42.

[0127] The first spring 41 and the second spring 42 are located in the pen barrel 1. The first spring 41 is configured to apply a spring force to the second slider 34 directly or indirectly in a direction away from the opening 11. The second spring 42 is configured to apply a spring force to the second slider 34 directly or indirectly in a direction away from the opening 11.

[0128] Specifically, a mounting opening 12 is provided on the side wall of the pen barrel 1. The mounting opening 12 on the side wall can accommodate the rotating component 31 in the rotation drive module 3, so that the rotating component 31 can rotate in the mounting opening 12. During rotation, the rotating component 31 can drive the first sliding member 33 and the second sliding member 34 on both sides to slide in the pen barrel 1 through the rotation drive unit 311. Under the driving action of the rotating component 31, the first sliding member 33 and the second sliding member 34 slide in opposite directions.

[0129] The pen tip 2 is protruded from the opening 11 of the pen barrel 1 by the first sliding member 33; the functional member 35 is protruded to the outside of the pen barrel 1 by the second sliding member 34.

[0130] In one embodiment of this application, the first slider 33 and the second slider 34 are sleeved together, and the first slider 33 and the second slider 34 can slide relative to each other.

[0131] Specifically, in order to achieve a compact structural design and to ensure that the first slider 33 and the second slider 34 cooperate to guide each other during relative sliding to ensure smooth sliding, the first slider 33 and the second slider 34 are sleeved together. Thus, when the rotating component 31 drives the first slider 33 and the second slider 34 to slide towards their respective ends of the pen barrel 1, the sleeved connection of the first slider 33 and the second slider 34 also serves a guiding function.

[0132] For example, both the first slider 33 and the second slider 34 are tubular structures. The first slider 33 can be inserted into the second slider 34 to achieve a sleeve connection, or the second slider 34 can be inserted into the first slider 33 to achieve a sleeve connection.

[0133] In one embodiment, the first sliding member 33 is provided with a sliding guide portion 332, and the second sliding member 34 is provided with a guide mating portion 342, wherein the sliding guide portion 332 and the guide mating portion 342 are slidably connected together.

[0134] Specifically, after the first slider 33 and the second slider 34 are sleeved together, in order to prevent relative rotation between the first slider 33 and the second slider 34 during their relative sliding process, the sliding guide part 332 is connected to the guide mating part 342 to cooperate in guiding the sliding, so that the first slider 33 and the second slider 34 can slide smoothly without relative rotation between them, thus ensuring that the rotating part 31 can drive the first slider 33 and the second slider 34 to slide smoothly.

[0135] In another embodiment, the sliding guide portion 332 includes a first groove 3321 formed on the first sliding member 33, the first groove 3321 extending along the length direction of the first sliding member 33; the guiding mating portion 342 includes a guide rib 3421 formed on the second sliding member 34, the guide rib 3421 extending along the length direction of the second sliding member 34; the guide rib 3421 is inserted into the first groove 3321.

[0136] Specifically, when the sliding guide part 332 and the guide mating part 342 cooperate to guide the relative sliding of the first sliding member 33 and the second sliding member 34, the guide rib 3421 and the first sliding groove 3321 can cooperate to guide the relative sliding between the first sliding member 33 and the second sliding member 34.

[0137] In one embodiment, the sliding guide portion 332 includes an elastic claw 3322 formed on the first sliding member 33, and the guide mating portion 342 includes a second sliding groove 3422 formed on the second sliding member 34. The elastic claw 3322 is engaged in the second sliding groove 3422 and can slide in the second sliding groove 3422.

[0138] Specifically, the first sliding member 33 and the second sliding member 34 are sleeved together and can slide relative to each other. In order to facilitate assembly and further meet the requirements of sliding guidance, an elastic claw 3322 is provided on the first sliding member 33, and correspondingly, a second sliding groove 3422 is provided on the second sliding member 34.

[0139] During the assembly process, as the first sliding member 33 and the second sliding member 34 are sleeved together, the elastic claw 3322 can be locked in the second slide groove 3422, thereby enabling the first sliding member 33 and the second sliding member 34 to be assembled together through the cooperation of the elastic claw 3322 and the second slide groove 3422.

[0140] After the first slider 33 and the second slider 34 are assembled together, the elastic claw 3322 prevents the first slider 33 and the second slider 34 from separating, thus facilitating the insertion of the assembled first slider 33 and the second slider 34 into the pen barrel 1.

[0141] Furthermore, during use, when the first slider 33 and the second slider 34 slide relative to each other, the elastic claw 3322 can slide in the second groove 3422 to guide the smooth relative sliding between the first slider 33 and the second slider 34, thereby improving the smoothness of use.

[0142] In another embodiment, the inner wall of the pen barrel 1 is provided with a guide protrusion 16, and the first sliding member 33 or the second sliding member 34 is provided with a guide groove 344, which extends along the length direction of the pen barrel 1.

[0143] The guide protrusion 16 is slidably disposed in the guide groove 344.

[0144] Specifically, to further guide the first slider 33 and the second slider 34, a guide protrusion 16 can be provided on the inner wall of the pen barrel 1. The guide protrusion 16 cooperates with the guide groove 344 provided on the first slider 33 or the second slider 34 to guide the sliding of the first slider 33 or the second slider 34. Taking the second slider 34 as an example, during the sliding process, the guide groove 344 cooperates with the guide protrusion 16 to guide the sliding second slider 34. At the same time, a sliding guide structure is also provided between the first slider 33 and the second slider 34, thereby enabling the first slider 33 and the second slider 34 to slide smoothly in the pen barrel 1.

[0145] In one embodiment of this application, the rotation drive part 311 protrudes from the inner surface of the rotation component 31, and the outer periphery of the rotation drive part 311 forms a rotation drive curved surface 312.

[0146] The first sliding sub-drive unit 331 and the second sliding sub-drive unit 341 are attached to the rotary drive surface 312;

[0147] During the process of the rotating component 31 rotating to drive the first sliding member 33 to move toward the opening 11, the distance between the part of the first sliding sub-driving part 331 that contacts the rotating driving surface 312 and the rotation center line of the rotating component 31 gradually increases.

[0148] As the rotating component 31 rotates to drive the second sliding member 34 to move toward the through hole 15, the distance between the part of the second sliding sub-driving part 341 that contacts the rotating driving surface 312 and the rotation center line of the rotating component 31 gradually increases.

[0149] Specifically, the rotary drive unit 311 protrudes from the inner surface of the rotating component 31 to meet the requirement of lateral contact with the sliding sub-drive units on the two sliders. The design of the rotary drive surface 312 formed by the rotary drive unit 311 must ensure that, during the rotation of the rotating component 31, the rotary drive surface 312 can contact the sliding sub-drive units, allowing the two sliders to move towards the corresponding ends of the pen barrel 1 as the rotating component 31 rotates.

[0150] As the user rotates the rotating component 31 to extend the pen tip 21 and the functional component 35 to the outside of the pen barrel 1, the rotating drive surface 312 abuts against the first sliding sub-drive part 331 and the second sliding sub-drive part 341. Furthermore, as the rotating component 31 rotates, the distance between the contact point of the rotating drive surface 312 and the two sliding sub-drive parts and the rotation center line of the rotating component 31 gradually increases, thereby enabling the pen tip 21 and the functional component 35 to extend to the outside of the pen barrel 1.

[0151] Conversely, when the user finishes writing and rotates the rotating component 31 again, the rotation drive surface 312 will tend to detach from the first slider drive part 331 and the second slider drive part 341. However, under the action of the first spring 41 and the second spring 42, the first slider drive part 331 and the second slider drive part 341 will always remain in contact with the rotation drive surface 312.

[0152] Specifically, as the rotating component 31 rotates and the first sliding component 32 moves away from the opening 11 under the action of the first spring 41, the distance between the part of the first sliding sub-drive part 331 that contacts the rotating drive surface 312 and the rotation center line of the rotating component 31 gradually decreases; as the rotating component 31 rotates and the second sliding component 32 moves away from the through hole under the action of the second spring 42, the distance between the part of the second sliding sub-drive part 341 that contacts the rotating drive surface 312 and the rotation center line of the rotating component 31 gradually decreases.

[0153] Similarly, for the specific surface structure of the rotary drive surface 312, a raised arc surface is generally adopted. This enables the two sliders to slide by contacting and cooperating with the first slider drive part 331 and the second slider drive part 341. At the same time, the raised arc surface can also smoothly drive the sliders to slide, thereby improving the smoothness of operation.

[0154] In addition, during the process of the pen tip 21 and the functional component 35 retracting in the opposite direction to the pen barrel 1 under the action of the first spring 41 and the second spring 42, the rotation drive surface 312 can better cooperate with the movement of the slider drive part by utilizing its smooth curved surface structure.

[0155] In one embodiment of this application, the portion of the first sliding sub-drive unit 331 and the second sliding sub-drive unit 341 that contacts the rotary drive surface 312 is an arc-shaped surface.

[0156] Specifically, the slider drive unit is provided with an arc-shaped surface, which allows the slider drive unit to smoothly contact and cooperate with the rotary drive curved surface 312 and slide smoothly relative to it. This is more conducive to improving the smoothness of the sliding of the two sliders driven by the rotary component 31, thereby improving the user experience and reducing the occurrence of jamming.

[0157] In one embodiment of this application, the first slider 33 and the second slider 34 are tubular structures;

[0158] The first sliding member 33 has a first sub-mounting hole 333 on its side wall, and the second sliding member 34 has a second sub-mounting hole 343 on its side wall. The first sub-mounting hole 333 and the second sub-mounting hole 343 are strip-shaped.

[0159] The inner surface of the rotating component 31 is also provided with a connecting shaft 313, and a stop plate 314 is also provided on the connecting shaft 313. The connecting shaft 313 passes through the first sub-mounting hole 333 and the second sub-mounting hole 343, and the stop plate 314 is located inside the first sliding member 33 or the second sliding member 34.

[0160] Specifically, to improve assembly reliability and ensure good contact and fit between the rotary drive unit 311 and the two sliding sub-drive units, the rotary component 31 is provided with a stop plate 314 via the connecting shaft 313. During assembly, the stop plate 314 can be sequentially inserted into the first sub-mounting hole 333 and the second sub-mounting hole 343, and the stop plate 314 prevents the connecting shaft 313 from disengaging from the first sub-mounting hole 333 and the second sub-mounting hole 343, thereby ensuring that the rotary component 31 is securely assembled with the first sliding member 33 and the second sliding member 34.

[0161] During use, the rotating component 31 is restricted by the stop plate 314 and connected to the first sliding component 33 and the second sliding component 34 by the connecting shaft 313, thereby ensuring good contact and cooperation between the rotating drive unit 311 and the two sliding sub-drive units, so as to ensure that during the rotation of the rotating component 31, the rotating drive unit 311 drives the sliding drive unit 321 to drive the sliding component 32 to slide smoothly.

[0162] In one embodiment, the two ends of the rotary drive unit 311 away from the rotation center line of the rotary component 31 are respectively provided with first positioning notches 315;

[0163] When the pen tip 21 of the pen refill 2 extends outside the opening 11 and is in a writing state, the first sliding sub-drive part 331 is engaged in the first positioning notch 315;

[0164] When the functional component 35 extends outside the through hole and is in a writing state, the second sliding sub-drive part 341 is engaged in the first positioning notch 315.

[0165] Specifically, to ensure the pen tip 21 remains stable outside the pen barrel 1 after it extends beyond the pen body 1, thus meeting the user's requirement for smooth writing, the first sliding sub-drive unit 331 engages with the first positioning notch 315 after the user rotates the rotating component 31 to extend the pen tip 21 beyond the pen body 1. Similarly, the second sliding sub-drive unit 341 engages with the other first positioning notch 315. This ensures that the rotating component 31 remains stationary without rotation under minimal external force, and that the movement of the two sliding components is restricted by the cooperation of the first positioning notch 315 with the two sliding sub-drive units, thus ensuring that the pen tip 21 remains exposed during writing.

[0166] In another embodiment, a second positioning notch 316 is provided at the middle position of each of the two sides of the rotary drive unit 311;

[0167] When the pen tip 21 of the pen refill 2 is retracted to its maximum position inside the pen barrel 1, the first sliding sub-drive part 331 is engaged in the second positioning notch 316;

[0168] When the functional component 35 is retracted to its maximum position within the pen barrel 1, the second sliding sub-drive part 341 is engaged in the second positioning notch 316.

[0169] Specifically, after the pen tip 21 retracts into the pen barrel 1, the first sliding sub-drive unit 331 engages in the second positioning notch 316 to position the retracted pen tip 21. Similarly, the second sliding sub-drive unit 341 engages in another second positioning notch 316.

[0170] By setting up a rotation drive module 3, the rotating component 31 in the rotation drive module 3 can rotate on the pen barrel 1, while the two sliding components can slide in the pen barrel 1. During the rotation of the rotating component 31, the rotational motion of the rotating component 31 can be converted into the linear sliding of the sliding component through the cooperation of the rotation drive unit 311 and the sliding sub-drive unit. In this way, during use, the user can rotate the rotating component 31 to smoothly drive the sliding component to move towards the corresponding end of the pen barrel 1, so that the pen core 2 can smoothly extend to the outside of the pen barrel 1 for writing operations. At the same time, the added functional component 35 can also extend to the outside of the pen barrel 1 to enrich the functionality of the writing pen, thereby simplifying the overall structure and improving the smoothness of use.

[0171] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
