[0002] Pens are commonly used stationery in people's daily lives. According to different ways of use, pens are divided into push pens and uncap pens, etc. Pens that use spiral switches are popularized due to the novelty of their use. For example, Chinese Patent Publication No. CN110395067A discloses a magnetic rotary telescopic pen that uses a rotational method to achieve the extension and retraction of the pen core. In order to achieve the function of rotating and driving the refill to extend and retract, a clamping component with a polygonal clamping groove is configured, and cooperates with the clamping protrusion on the pen barrel to drive the refill to extend and retract during the rotation process. The polygonal clamping groove provided on the clamping component leads to a more complex structure, greater processing difficulty and greater assembly difficulty, and during the rotation process, the relative sliding of the polygonal clamping groove and the clamping protrusion is prone to jamming, resulting in poor smoothness of use. In view of this, how to design a stationery that simplifies the overall structure and improves the smoothness of use is a technical problem to be solved by the present invention.

[0007] During the process that the rotating component rotates and the sliding component moves in a direction away from the opening under the action of the return spring, the distance between the portion where the sliding driving part contacts the rotating driving curved surface and the rotation centerline of the rotating component gradually decreases.

[0008] In one embodiment of the present application, the portion where the sliding driving portion contacts the rotating driving curved surface is an arc-shaped surface.

[0009] In one embodiment of the present application, the sliding component is a sleeve, and the sliding driving part is formed on the tube wall of the sleeve; The pen core is inserted into the sleeve.

[0010] In one embodiment of the present application, a strip-shaped mounting hole is provided on the tube wall of the sliding component, and the strip-shaped mounting hole includes a first opening section and a second opening section, the first opening section and the second opening section are connected to each other, and the width of the first opening section is smaller than the width of the second opening section; A connecting shaft is also provided on the inner surface of the rotating component, and a stop plate is also provided on the connecting shaft. The connecting shaft passes through the strip mounting hole and is located in the first opening section. The width of the stop plate is greater than the width of the first opening section, and the width of the stop plate is less than the width of the second opening section.

[0011] In one embodiment of the present application, the surface of the stop plate opposite to the pen core is a concave surface, and the concave surface matches the outer wall contour of the pen core.

[0013] In one embodiment of the present application, a first positioning notch is provided at an end of the rotation driving portion away from the rotation center line of the rotating component; When the pen tip of the pen core is extended to the outside of the opening and is in a writing state, the sliding drive part is stuck in the first positioning notch.

[0014] In one embodiment of the present application, a second positioning notch is provided at an end of the rotation driving portion adjacent to the rotation center line of the rotating component; When the pen tip of the pen core is retracted to the maximum position in the pen barrel, the sliding drive part is stuck in the second positioning notch.

[0019] Embodiment 1, as Figure 1-Figure 7 As shown, the present invention provides a writing pen, comprising: A pen holder 1, an opening 11 is formed at one end of the pen holder 1, and a mounting opening 12 is provided on the side wall of the pen holder 1; A pen core 2, wherein the pen core 2 is slidably disposed in the pen holder 1; a return spring 4, the return spring 4 being disposed in the pen holder 1 and configured to directly or indirectly apply an elastic force to the pen core 2 in a direction away from the opening 11; A rotation driving module 3, wherein the rotation driving module 3 comprises a rotation component 31 and a sliding component 32, wherein the rotation component 31 is provided with a rotation driving portion 311, and the sliding component 32 is provided with a sliding driving portion 321, and the rotation driving portion 311 and the sliding driving portion 321 are close to each other; The sliding component 32 is slidably disposed in the pen holder 1, the sliding component 32 is connected to the pen core 2, and the rotating component 31 is rotatably disposed in the mounting opening 12; The rotating component 31 is configured to rotate in the installation port 12 to push the sliding driving part 321 to slide toward the opening 11 through the rotating driving part 311, and the sliding component 32 is configured to slide toward the opening 11 while driving the pen core 2 to slide toward the opening 11 synchronously.

[0020] Specifically, a mounting opening 12 is provided on the side wall of the pen body 1, and the mounting opening 12 on the side wall can meet the requirements of mounting the rotating component 31 in the rotating driving module 3, so that the rotating component 31 can rotate in the mounting opening 12. The pen core 2 is located in the pen body 1 and can slide in the pen body 1. At the same time, the sliding component 32 in the rotating driving module 3 can also slide in the pen body 1, and the sliding of the sliding component 32 can drive the pen head 21 of the pen core 2 to extend from the opening 11 to meet the writing requirements.

[0021] During use, the rotating component 31 and the sliding component 32 cooperate with each other through the rotating drive part 311 and the sliding drive part 321 which are close to each other. When the pen tip 21 of the pen core 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 rotating motion of the rotating component 31 into the sliding motion of the sliding component 32.

[0022] When the user drives the rotating part 31 to rotate, the rotating driving part 311 abuts against the sliding driving part 321 to drive the sliding part 32 to slide. The rotating driving part 311 and the sliding driving part 321 abut against each other on the outside instead of using a guide groove. This makes it possible for the rotating part 31 to push the sliding part 32 to slide more smoothly during rotation, thereby improving the smoothness of use.

[0023] In addition, in order to enable the pen core 2 to automatically reset, after the rotating component 31 is rotated so that the sliding component 32 drives the pen tip 21 of the pen core 2 to extend out of the opening 11; when the user rotates the rotating component 31 again, the rotating drive part 311 of the rotating component 31 will have a tendency to move away from the sliding drive part 321, and at this time, under the action of the reset spring 4, the pen core 2 will be retracted back into the pen shaft 1 under 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 achieving a smooth retraction of the pen core 2.

[0024] In one embodiment of the present application, the rotation driving portion 311 protrudes from the inner surface of the rotating component 31 , and the outer circumference of the rotation driving portion 311 forms a rotation driving curved surface 312 ; The sliding driving portion 321 is in contact with the rotating driving curved surface 312; During the process that the rotating component 31 rotates to drive the sliding component 32 to move toward the opening 11 , the distance between the contacting portion of the sliding driving portion 321 and the rotating driving curved surface 312 and the rotation center line of the rotating component 31 gradually increases.

[0025] Specifically, the rotation driving part 311 protrudes from the inner surface of the rotating component 31 to meet the requirement of abutting against the sliding driving part 321 on the sliding component 32 at the side. Among them, the surface design of the rotation driving curved surface 312 formed by the rotation driving part 311 needs to meet the requirement that when the rotating component 31 rotates, the rotation driving curved surface 312 can contact the sliding driving part 321 so that the sliding component 32 moves toward the opening 11 of the pen holder 1 as the rotating component 31 rotates.

[0026] Specifically, when the user rotates the rotating component 31 to extend the pen tip 21 for writing, the rotating drive surface 312 is abutted against the sliding drive part 321, and as the pen core 2 moves, the distance between the contact part of the rotating drive surface 312 and the sliding drive part 321 and the rotation center line of the rotating component 31 gradually increases, so that the pen tip 21 of the pen core 2 can be extended to the outside of the opening 11.

[0027] On the contrary, when the user finishes writing and rotates the rotating member 31 again, the rotating driving curved surface 312 will have a tendency to separate from the sliding driving portion 321, and under the action of the return spring 4, the return spring 4 transmits elastic force to the sliding member 32 through the pen core 2, so that the sliding driving portion 321 always sticks to the rotating driving curved surface 312.

[0028] Specifically, when the user rotates the rotating part 31 to retract the pen tip 21, when the rotating part 31 rotates and the sliding part 32 is moved away from the opening 11 by the return spring 4, the distance between the part where the sliding drive part 321 contacts the rotating drive surface 312 and the rotation center line of the rotating part 31 gradually decreases.

[0029] For the specific curved surface structure of the rotating driving surface 312, a convex arc surface is generally used, so that the sliding component 32 can be pushed to slide through the contact and cooperation between the rotating driving surface 312 and the sliding driving part 321. At the same time, the convex arc surface can also smoothly drive the sliding component 32 to slide to improve the smoothness of the operation.

[0030] In addition, when the pen tip 21 is retracted back to the pen holder 1 under the action of the return spring 4, the rotation driving curved surface 312 can better cooperate with the movement of the sliding driving part 321 by utilizing its smooth curved surface structure.

[0031] In one embodiment of the present application, the portion where the sliding driving portion 321 contacts the rotating driving curved surface 312 is an arc-shaped surface.

[0032] Specifically, the sliding drive part 321 is provided with an arc surface, so that the sliding drive part 321 can smoothly contact and cooperate with the rotating drive curved surface 312 and slide smoothly relative to it, which is more conducive to improving the smoothness of the sliding of the sliding part 32 driven by the rotating part 31, thereby improving the user experience and reducing the occurrence of jamming.

[0033] In one embodiment of the present application, the sliding component 32 is a sleeve, and the sliding driving part 321 is formed on the tube wall of the sleeve; The pen core 2 is inserted into the sleeve.

[0034] Specifically, the sliding component 32 adopts a sleeve structure, so that the pen core 2 can be inserted into the sliding component 32 to facilitate quick assembly of the two.

[0035] In addition, a sliding driving part 321 is formed on the outer tube wall of the sliding part 32 , and the sliding driving part 321 can be in good contact with the rotating driving part 311 formed on the inner surface of the rotating part 31 , so as to drive the sliding part 32 to slide smoothly through the rotating part 31 .

[0036] In one embodiment of the present application, a strip-shaped mounting hole 322 is provided on the tube wall of the sliding component 32, and the strip-shaped mounting hole 322 includes a first opening 11 section and a second opening 11 section, the first opening 11 section and the second opening 11 section are connected to each other, and the width of the first opening 11 section is smaller than the width of the second opening 11 section; 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 section. The width of the stop plate 314 is greater than the width of the first opening 11 section, and the width of the stop plate 314 is less than the width of the second opening 11 section.

[0037] Specifically, in order to improve the reliability of assembly and ensure good contact and cooperation between the rotating driving part 311 and the sliding driving part 321, the rotating component 31 is provided with a stop plate 314 through the connecting shaft 313. During the assembly process, the stop plate 314 can be inserted from the second opening 11 section into the strip-shaped mounting hole 322, and then the stop plate 314 moves to the first opening 11 section, so that the stop plate 314 will not be separated from the strip-shaped mounting hole 322.

[0038] During use, the rotating component 31 is restricted by the stop plate 314 and connected to the sliding component 32 using the connecting shaft 313, thereby ensuring good contact and cooperation between the rotating drive part 311 and the sliding drive part 321, so as to ensure that during the rotation of the rotating component 31, the rotating drive part 311 drives the sliding drive part 321 to drive the sliding component 32 to slide smoothly.

[0039] In one embodiment of the present application, the surface of the stop plate 314 opposite to the pen core 2 is a concave surface, and the concave surface matches the outer wall contour of the pen core 2 .

[0040] Specifically, the stop plate 314 is formed with a concave surface, so that in the writing state, the stop plate 314 can be more closely fitted to the surface of the pen core 2 , and the stop plate 314 is used to position and support the pen core 2 in the pen holder 1 .

[0041] In one embodiment of the present application, a concave portion is formed on the tube wall of the sliding component 32, and the concave portion forms an assembly surface, and the assembly surface is a plane; The sliding driving portion 321 is a protruding structure formed on the assembly surface, and the rotating driving portion 311 is arranged outside the assembly surface.

[0042] Specifically, the sliding component 32 adopts a sleeve structure, and the outer surface of the tube wall is generally an arc surface. In order to make the sliding drive part 321 contact well with the rotating 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 rotating component 31 and the sliding component 32 are assembled together, the rotating drive part 311 of the rotating component 31 is attached to the mounting surface and can be better attached to the sliding drive part 321.

[0043] In one embodiment of the present application, a first positioning notch 315 is provided at an end of the rotation driving portion 311 away from the rotation center line of the rotating component 31; When the pen tip 21 of the pen core 2 is extended out of the opening 11 and is in a writing state, the sliding driving part 321 is stuck in the first positioning notch 315 .

[0044] Specifically, in order to keep the pen tip 21 stably outside the pen barrel 1 after the pen tip 21 of the pen core 2 extends out of the pen barrel 1 to meet the user's requirement for stable writing, when the user rotates the rotating component 31 to extend the pen tip 21 out of the pen barrel 1, the sliding drive part 321 will be stuck in the first positioning notch 315. On the one hand, the rotating component 31 is kept stationary and does not rotate when a large external force is not applied, and on the other hand, the first positioning notch 315 cooperates with the sliding drive part 321 to limit the movement of the sliding component 32, so as to ensure that the pen tip 21 remains exposed in the writing state.

[0045] In another embodiment, the end of the rotation driving portion 311 adjacent to the rotation center line of the rotation component 31 is provided with a second positioning notch 316; When the pen tip 21 of the pen core 2 is retracted to the maximum position in the pen barrel 1 , the sliding drive part 321 is stuck in the second positioning notch 316 .

[0046] Specifically, when the pen tip 21 is retracted into the pen holder 1 , in order to position the retracted pen tip 21 , the sliding drive part 321 is stuck in the second positioning notch 316 .

[0047] In one embodiment of the present application, the pen body 1 includes a first rod body 13 and a second rod body 14, and the first rod body 13 and the second rod body 14 are detachably connected together; The opening 11 is formed on the first rod body 13 , and the mounting opening 12 is formed on the second rod body 14 .

[0048] Specifically, in order to facilitate the assembly of parts, the pen body 1 adopts a split structure, and the mounting end of the first rod body 13 and the mounting end of the second rod body 14 can be connected together by threaded connection. The free end of the first rod body 13 forms an opening 11 to meet the requirements of the extension and retraction of the pen head 21, and the second rod body 14 is provided with a mounting opening 12 to meet the installation requirements of the rotating component 31. After the pen core 2 is inserted into the sliding component 32, the sliding component 32 is inserted into the second rod body 14, and then the rotating component 31 is assembled into the mounting opening 12 to be connected with the sliding component 32 through the connecting shaft 313 and the stop plate 314, and finally, the first rod body 13 is connected to the second rod body 14.

[0049] The technical solution of the present invention has the following technical effects compared with the prior art: by providing an installation opening 12 on the rod wall of the pen barrel 1 to meet the installation requirements of the rotation drive module 3, the rotation component 31 in the rotation drive module 3 can rotate in the installation opening 12, and the rotation component 31 can drive the sliding component 32 to slide in the pen barrel 1 through the cooperation of the rotation drive part 311 and the sliding drive part 321 during the rotation process, so that the pen tip 21 of the pen core 2 can be extended out of the opening 11, and the sliding component 32 can be driven by the rotation component 31 to slide to drive the pen core 2 to move out of the pen barrel 1. Since the rotation drive part 311 and the sliding drive part 321 are abutted against each other, the rotational motion is converted into a linear motion, thereby avoiding the phenomenon of jamming during use due to the use of a polygonal card slot, and the use is smooth; and the overall structure of the rotation drive module 3 is simple and the internal matching relationship is only achieved by the external abutment between the rotation drive part 311 and the sliding drive part 321. The structure is relatively simple, and the processing difficulty and assembly difficulty are relatively small, so that the overall structure of the writing pen is simplified and the use smoothness is improved.

[0050] Embodiment 2, as Figure 8-Figure 17 As shown, the present application also provides a rotary writing pen, which is based on the above-mentioned embodiment 1, but differs in that an opening 11 is formed at one end of the pen shaft 1, a through hole 15 is formed at the other end of the pen shaft 1, and a mounting opening 12 is provided on the side wall of the pen shaft 1.

[0051] The rotary writing pen includes two sliding parts 32, namely a first sliding part 33 and a second sliding part 34. The first sliding part 33 is provided with a first sliding sub-driving part 331, and the second sliding part 34 is provided with a second sliding sub-driving part 341. The second sliding part 34 is also provided with a functional part 35. The rotation driving part 311 is located between the first sliding sub-driving part 331 and the second sliding sub-driving part 341.

[0052] The first sliding member 33 is used to install the pen core 2, so as to drive the pen tip 21 of the pen core 2 to extend out of the opening 11 of the pen barrel 1 for writing. The second sliding member 34 is provided with a functional member 35 as required, and the functional member 35 is set as required. For example, the functional member 35 can be a decoration, or the functional member 35 can be a heat-erasable head, or the functional member 35 can be an eraser. Here, there is no limitation on the specific entity of the functional member 35.

[0053] The rotating component 31 is rotatably disposed in the mounting opening 12 , and the first sliding member 33 and the second sliding member 34 are respectively slidably disposed in the pen barrel 1 .

[0054] The rotating member 31 is configured to rotate in the installation port 12 to push the first sliding sub-driving part 331 and the second sliding sub-driving part 341 to slide through the rotation driving part 311 .

[0055] The first sliding member 33 is configured to slide toward the opening 11 when the first sliding sub-driving part 331 is pushed so as to drive the pen tip 21 of the pen core 2 to extend out of the opening 11 .

[0056] The second sliding member 34 is configured to slide toward the through hole 15 when the second sliding sub-driving portion 341 is pushed, so as to drive the functional member 35 to extend out of the through hole 15 .

[0057] The sliding direction of the first sliding member 33 is opposite to the sliding direction of the second sliding member 34. In this way, when the first sliding member 33 and the second sliding member 34 move in opposite directions toward the outside of the pen barrel 1, the pen head 21 can be extended out of the pen barrel 1, and the functional member 35 can also be extended out of the pen barrel 1 synchronously, so as to enrich the use functions of the writing pen.

[0058] In addition, in order to meet the requirement of resetting, the rotary writing pen includes two resetting springs 4 , namely a first spring 41 and a second spring 42 .

[0059] The first spring 41 and the second spring 42 are located in the pen barrel 1, and the first spring 41 is configured to directly or indirectly apply an elastic force to the second sliding member 34 in a direction away from the opening 11; the second spring 42 is configured to directly or indirectly apply an elastic force to the second sliding member 34 in a direction away from the opening 11.

[0060] Specifically, a mounting opening 12 is provided on the side wall of the pen barrel 1, and the mounting opening 12 on the side wall can meet the requirements of mounting the rotating component 31 in the rotation drive module 3, so that the rotating component 31 can rotate in the mounting opening 12. During the rotation of the rotating component 31, 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.

[0061] The pen core 2 is driven by the first sliding member 33 so that the pen head 21 extends out of the opening 11 of the pen barrel 1 ; the functional member 35 is driven by the second sliding member 34 so that the functional member 35 extends out of the pen barrel 1 .

[0062] In one embodiment of the present application, the first sliding member 33 and the second sliding member 34 are sleeved together, and the first sliding member 33 and the second sliding member 34 can slide relative to each other.

[0063] Specifically, in order to achieve a compact structure design and ensure that the first sliding member 33 and the second sliding member 34 cooperate with each other to guide each other during the relative sliding process to ensure smooth sliding, the first sliding member 33 and the second sliding member 34 are sleeved together, so that when the first sliding member 33 and the second sliding member 34 are driven by the rotating member 31 to slide toward the corresponding end of the pen body 1, the sleeved first sliding member 33 and the second sliding member 34 can also play a guiding role.

[0064] For example, the first sliding member 33 and the second sliding member 34 are both tubular structures. The first sliding member 33 can be inserted into the second sliding member 34 to achieve a sleeve connection, or the second sliding member 34 can be inserted into the first sliding member 33 to achieve a sleeve connection.

[0065] In one embodiment, a sliding guide portion 332 is disposed on the first sliding member 33 , and a guide matching portion 342 is disposed on the second sliding member 34 . The sliding guide portion 332 and the guide matching portion 342 are slidably connected together.

[0066] Specifically, after the first sliding member 33 and the second sliding member 34 are sleeved together, in order to prevent the first sliding member 33 and the second sliding member 34 from rotating relative to each other during the relative sliding process, the sliding guide portion 332 is connected with the guide matching portion 342 to cooperate with the guide sliding, so that the first sliding member 33 and the second sliding member 34 can slide smoothly without relative rotation, so as to ensure that the rotating component 31 can drive the first sliding member 33 and the second sliding member 34 to slide smoothly.

[0067] In another embodiment, the sliding guide portion 332 includes a first sliding groove 3321 formed on the first sliding member 33, and the first sliding groove 3321 extends along the length direction of the first sliding member 33; the guide matching portion 342 includes a guide rib 3421 formed on the second sliding member 34, and the guide rib 3421 extends along the length direction of the second sliding member 34; the guide rib 3421 is inserted into the first sliding groove 3321.

[0068] Specifically, when the sliding guide portion 332 and the guide matching portion 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.

[0069] In one embodiment, the sliding guide portion 332 includes an elastic claw 3322 formed on the first sliding member 33, and the guide matching portion 342 includes a second sliding groove 3422 formed on the second sliding member 34, and the elastic claw 3322 is clamped in the second sliding groove 3422 and can slide in the second sliding groove 3422.

[0070] 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.

[0071] During the assembly process, when the first sliding member 33 and the second sliding member 34 are sleeved together, the elastic claw 3322 can be stuck in the second sliding groove 3422, so that the first sliding member 33 and the second sliding member 34 can cooperate with each other through the elastic claw 3322 and the second sliding groove 3422 to achieve the two being assembled together.

[0072] After the first sliding member 33 and the second sliding member 34 are assembled together, the elastic claw 3322 prevents the first sliding member 33 and the second sliding member 34 from being separated, thereby facilitating the assembly of the first sliding member 33 and the second sliding member 34 into the pen body 1 .

[0073] Furthermore, during use, when the first sliding member 33 and the second sliding member 34 slide relative to each other, the elastic claw 3322 can slide in the second sliding groove 3422 to guide the first sliding member 33 and the second sliding member 34 to slide relative to each other smoothly, thereby improving the smoothness of use.

[0074] In another embodiment, the inner wall of the pen holder 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, and the guide groove 344 extends along the length direction of the pen holder 1; The guide protrusion 16 is slidably disposed in the guide groove 344 .

[0075] Specifically, in order to further guide the first sliding member 33 and the second sliding member 34, a guide protrusion 16 may be provided on the inner wall of the pen body 1, and the guide protrusion 16 cooperates with the guide groove 344 provided on the first sliding member 33 or the second sliding member 34 to guide the sliding of the first sliding member 33 or the second sliding member 34. Taking the guide groove 344 provided on the second sliding member 34 as an example, during the sliding process of the second sliding member 34, the guide groove 344 cooperates with the guide protrusion 16 to guide the sliding second sliding member 34. At the same time, a sliding guide structure is also provided between the first sliding member 33 and the second sliding member 34, so that the first sliding member 33 and the second sliding member 34 can slide smoothly in the pen body 1.

[0076] In one embodiment of the present application, the rotation driving portion 311 protrudes from the inner surface of the rotating component 31 , and the outer circumference of the rotation driving portion 311 forms a rotation driving curved surface 312 ; The first sliding sub-driving part 331 and the second sliding sub-driving part 341 are attached to the rotating driving curved surface 312; 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 portion where the first sliding sub-driving portion 331 contacts the rotating driving curved surface 312 and the rotation center line of the rotating component 31 gradually increases; During the process of the rotating component 31 rotating to drive the second sliding member 34 to move toward the through hole 15 , the distance between the portion where the second sliding driving portion 341 contacts the rotating driving curved surface 312 and the rotation centerline of the rotating component 31 gradually increases.

[0077] Specifically, the rotation driving part 311 protrudes from the inner surface of the rotating component 31 to meet the requirement of abutting against the sliding sub-driving parts on the two sliding parts at the side. Among them, the surface design of the rotation driving curved surface 312 formed by the rotation driving part 311 needs to meet the requirement that when the rotating component 31 rotates, the rotation driving curved surface 312 can contact the sliding sub-driving part so that the two sliding parts move toward the corresponding end direction of the pen body 1 as the rotating component 31 rotates.

[0078] When the user rotates the rotating part 31 to extend the pen tip 21 and the functional part 35 to the outside of the pen body 1, the rotating drive surface 312 abuts against the first sliding sub-driving part 331 and the second sliding sub-driving part 341, and as the rotating part 31 rotates, the distance between the contact part between the rotating drive surface 312 and the two sliding sub-driving parts and the rotation center line of the rotating part 31 gradually increases, so as to enable the pen tip 21 and the functional part 35 to be extended to the outside of the pen body 1.

[0079] On the contrary, when the user finishes writing and rotates the rotating member 31 again, the rotating driving curved surface 312 will have a tendency to separate from the first slider driving part 331 and the second slider driving part 341, and under the action of the first spring 41 and the second spring 42, the first slider driving part 331 and the second slider driving part 341 always stick to the rotating driving curved surface 312.

[0080] Specifically, during the process of the rotating component 31 rotating and the first sliding component 32 being acted upon by the first spring 41 to move in a direction away from the opening 11, the distance between the portion where the first sliding sub-driving portion 331 contacts the rotating driving curved surface 312 and the rotation centerline of the rotating component 31 gradually decreases; during the process of the rotating component 31 rotating and the second sliding component 32 being acted upon by the second spring 42 to move in a direction away from the through hole, the distance between the portion where the second sliding sub-driving portion 341 contacts the rotating driving curved surface 312 and the rotation centerline of the rotating component 31 gradually decreases.

[0081] Similarly, for the specific curved surface structure of the rotating driving surface 312, a convex arc surface is generally used, so that the two sliding parts can be pushed to slide through the contact and cooperation between the rotating driving surface 312 and the first sliding sub-driving part 331 and the second sliding sub-driving part 341; at the same time, the convex arc surface can also smoothly drive the sliding parts to slide to improve the smoothness of the operation.

[0082] In addition, when the pen tip 21 and the functional part 35 are retracted back to the pen holder 1 under the action of the first spring 41 and the second spring 42, the rotation driving curved surface 312 can better cooperate with the movement of the sliding sub-driving part by utilizing its smooth curved surface structure.

[0083] In an embodiment of the present application, the contact portions of the first sliding sub-driving portion 331 and the second sliding sub-driving portion 341 with the rotation driving curved surface 312 are arc-shaped surfaces.

[0084] Specifically, the sliding sub-driving part is provided with an arc surface, so that the sliding sub-driving part can smoothly contact and cooperate with the rotating driving surface 312 and slide smoothly relative to it, which is more conducive to improving the smoothness of the rotating part 31 driving the two sliding parts to slide, thereby improving the user experience and reducing the occurrence of jamming.

[0085] In one embodiment of the present application, the first sliding member 33 and the second sliding member 34 are tubular structures; A first sub-mounting hole 333 is provided on the side wall of the first sliding member 33, and a second sub-mounting hole 343 is provided on the side wall of the second sliding member 34. The first sub-mounting hole 333 and the second sub-mounting hole 343 are in a strip-shaped structure. 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 .

[0086] Specifically, in order to improve the reliability of assembly and ensure good contact and cooperation between the rotating driving part 311 and the two sliding sub-driving parts, the rotating component 31 is provided with a stop plate 314 through the connecting shaft 313. During the assembly process, the stop plate 314 can be inserted into the first sub-mounting hole 333 and the second sub-mounting hole 343 in sequence, and the stop plate 314 prevents the connecting shaft 313 from being separated from the first sub-mounting hole 333 and the second sub-mounting hole 343, thereby making the rotating component 31 and the first sliding member 33 and the second sliding member 34 firmly assembled together.

[0087] 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 using the connecting shaft 313, thereby ensuring good contact and cooperation between the rotating drive part 311 and the two sliding sub-drive parts, so as to ensure that during the rotation of the rotating component 31, the rotating drive part 311 drives the sliding drive part 321 to drive the sliding component 32 to slide smoothly.

[0088] In one embodiment, the two ends of the rotation driving portion 311 away from the rotation center line of the rotating component 31 are respectively provided with first positioning notches 315; When the pen tip 21 of the pen core 2 is extended out of the opening 11 and is in a writing state, the first sliding sub-driving part 331 is stuck in the first positioning notch 315; When the functional part 35 is extended to the outside of the through hole and is in a writing state, the second sliding sub-driving part 341 is stuck in the first positioning notch 315 .

[0089] Specifically, in order to keep the pen tip 21 stably outside the pen barrel 1 after the pen tip 21 of the pen core 2 extends out of the pen barrel 1 to meet the user's requirement for stable writing, when the user rotates the rotating component 31 to make the pen tip 21 extend out of the pen barrel 1, the first sliding sub-driving part 331 will be stuck in the first positioning notch 315, and similarly, the second sliding sub-driving part 341 will be stuck in another first positioning notch 315. On the one hand, the rotating component 31 is kept stationary and will not rotate when subjected to a large external force, and on the other hand, the first positioning notch 315 cooperates with the two sliding sub-driving parts to limit the movement of the two sliding parts, so as to ensure that the pen tip 21 remains in an exposed writing state.

[0090] In another embodiment, the middle positions of both sides of the rotation driving part 311 are respectively provided with second positioning notches 316; When the pen tip 21 of the pen core 2 is retracted to the maximum position in the pen holder 1, the first slider driving part 331 is stuck in the second positioning notch 316; When the functional member 35 is retracted to the maximum position in the pen barrel 1 , the second sliding sub-driving portion 341 is stuck in the second positioning notch 316 .

[0091] Specifically, when the pen tip 21 is retracted into the pen holder 1 , the first sliding sub-driving part 331 is stuck in the second positioning notch 316 in order to position the retracted pen tip 21 . Similarly, the second sliding sub-driving part 341 is stuck in another second positioning notch 316 .

[0092] By setting up a rotation drive module 3, the rotation component 31 in the rotation drive module 3 can rotate on the pen barrel 1, and the two sliding parts can slide in the pen barrel 1. During the rotation of the rotation component 31, the rotation movement of the rotation component 31 can be converted into linear sliding of the sliding part through the cooperation of the rotation drive part 311 and the sliding sub-driving part. In this way, during use, the user can rotate the rotation component 31 to smoothly drive the sliding part to move toward the corresponding end direction of the pen barrel 1, so that the pen core 2 can be smoothly extended to the outside of the pen barrel 1 for writing operations. At the same time, the added functional part 35 can also be extended 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.

[0093] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
