Description

Technical Field

[0001] This application relates to the technical field of writing tools, and specifically relates to a two-way moving pen. Background Art

[0002] The click-type or flip-type pen (gel pen structure) is a writing tool that can control the telescopic movement of the pen tip by pressing. This structure does not require a pen cap to be sleeved at the pen tip, and the telescopic movement of the pen tip is achieved by pressing; currently, the structure of this type of writing tool generally includes a pen barrel, a pen core, a gear, a lower rotating part, and a spring and other components. The spring is arranged at the lower end of the pen core to abut against the protrusion on the outer wall of the pen core. The gear and the lower rotating part are interrelated. Through the pressing action, the gear and the teeth on the lower rotating part cooperate with each other, and then combined with the tooth groove structure inside the pen barrel, the rotation of the lower rotating part and the alternation of the axial upper and lower positions are realized. The lower rotating part will push the pen core, and under the action of the spring, the pen tip of the pen core extends or retracts into the pen barrel, thereby realizing the telescopic movement of the pen core. When in use, the pen tip extends, and when not in use, the pen tip retracts to avoid ink pollution; this type of pen structure is a conventional structure for realizing the contraction of the pen core; however, with the increasing demand of users for different functions and display effects of pens, how to set IP decoration parts with different shapes on the pen, and this IP decoration part structure can follow the telescopic movement of the pen tip and the rotation of the lower rotating part to realize the up and down position movement and circumferential position conversion, so as to give users a brand-new pen that can synchronously present the telescopic function of the pen tip and the visual effect of the IP decoration part structure during the operation process has become a demand. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, this application provides a two-way moving pen that can realize the conversion of the up and down axial position and the circumferential position of the IP decoration part set on the pen, and at the same time can also realize the flip function of the pen core, so that the function and the visual effect can be synchronously presented.

[0004] To solve the above technical problems, the technical solution adopted in this application is: a two-way moving pen, the structure of the pen includes a pen barrel, an IP decoration part, a slider, a pen core, a first flip component and a second flip component located inside the pen barrel; the IP decoration part and the slider are connected to the first flip component, and the first flip component is used to drive the IP decoration part to move up and down and rotate circumferentially; the second flip component is located below the first flip component and is linked with the first flip component; the first flip component moves up and down and drives the second flip component to drive the pen core to extend or retract relative to the pen barrel.

[0005] With the above structure, two sets of flipping components are arranged in the pen barrel of the present application, and the two sets of flipping components are associated with each other to achieve interlocking. Among them, the first flipping component can achieve axial up-and-down driving and circumferential rotation of the IP decorative part, so that the structure of the IP decorative part can present different positions and angles, realizing the visual transformation effect of the writing instrument, thus meeting the needs of different users for the shape and visual transformation of the writing instrument; and the second set of flipping components still undertakes the driving function for the pen core, realizing the extending and retracting actions of the pen core to meet the functional requirements of existing flipping writing instruments or pressing writing instruments; moreover, the first flipping component and the second flipping component are associated and interlocked with each other, and the second flipping component can be driven during the operation of the first flipping component. Therefore, in one writing instrument, the IP decorative part and the pen core can move in and out bidirectionally at the same time, and at the same time, the axial up-and-down position and circumferential rotation of the IP decorative part are changed, achieving the technical effect of synchronously presenting the visual effects of both the telescopic function of the pen core and the angle and position changes of the IP decorative part.

[0006] Furthermore, the first flipping component includes an upper rod lining inside the upper pen barrel, and a first guide rail is arranged on the inner wall of the upper rod lining; an upper rotating part fixedly connected to the IP decorative part, a slider is arranged between the IP decorative part and the upper rotating part, and the slider is driven to move up and down by the pen clip. A first wall gear is arranged on the outer wall of the upper rotating part, and a first end gear is arranged at the lower end of the upper rotating part; a second end gear inside the upper pen barrel, the first end gear and the second end gear are arranged opposite to each other, and a first elastic part is arranged between the end wall of the upper rotating part and the second end gear; with this structure, the overall structure of the first flipping component is formed. When the pen clip drives the slider to move downward, the first elastic part is compressed. At this time, the slider abuts against the upper rotating part and also moves downward. The first wall gear slides in the first guide rail, and then gradually the first end gear meshes with the second end gear to achieve circumferential driving of the upper rotating part, so that the upper rotating part is located in different tracks of the first guide rail, thereby realizing the change of the up-and-down positions at the axial direction. During this process, since the IP decorative part is fixedly connected to the rotating part, the IP decorative part also realizes the change of the axial up-and-down position and the circumferential angle, giving users different visual presentation effects.

[0007] Furthermore, on both sides of the tooth tip of the tooth of the first end gear, there are provided beveled tooth surfaces. Correspondingly, on one side of the tooth tip of the second end gear, there is a beveled tooth surface, and on the other side, there is a vertical tooth surface. With this structure, during the contact process between the first end gear and the second end gear, due to the setting of the tooth surfaces, when the upper rotating member is compressed, it can drive the upper rotating member to rotate circumferentially under the guidance of the beveled tooth surface of the second end gear. When the first elastic member is no longer pressed and returns to its extended state, it will push the upper rotating member up again, and the matching position between the first wall gear and the first guide rail on its outer peripheral wall also changes. Thus, different matches between the upper rotating member and the axial position points of the first guide rail are achieved, realizing the circumferential and axial position changes of the upper rotating member and the IP decoration member thereon.

[0008] Furthermore, on the end of each tooth of the first wall gear close to the IP decoration member, there is provided a beveled tooth surface that is inclined on one side. The first guide rail includes a first tooth groove and a first groove wall. At the end of the first groove wall, there are provided a first guiding surface and a second guiding surface. The first guiding surface and the second guiding surface are respectively located on both sides of the first tooth groove. The first guiding surface is used to guide the first wall gear into the first tooth groove, and the second guiding surface is used to guide the beveled tooth surface of the first wall gear to abut against it. With this structure, during the circumferential rotation of the upper rotating member, according to the mutual cooperation of the above-mentioned guiding surface, tooth groove, and beveled tooth surface, when the first wall gear is located in the first tooth groove, the upper rotating member is located at the first axial position point (high point, closer to the upper end of the pen barrel), and at this time, the IP decoration member is located at the high point in the axial direction. When the beveled tooth surface of the first wall gear abuts against the second guiding surface, the upper rotating member is located at the second axial position point (low point, that is, moving downward, slightly away from the upper end of the pen barrel), and at this time, the IP decoration member is located at the low point in the axial direction. By repeatedly pressing, the change of two axial position points of the IP decoration member is realized, and at the same time, the circumferential angle of the IP decoration member also changes during this process.

[0009] Furthermore, the tooth tips of the first end gear and the second end gear are arranged in a staggered manner. With this structure, that is, the tooth tips of the two groups of end gears are not completely aligned axially with each other, but are arranged in a staggered manner. In the process of the first end gear and the second end gear abutting against each other, through this staggering, the beveled tooth surface of the end gear of the upper rotating member can be guided along the beveled tooth surface of the second end gear, ensuring the stable change of the circumferential angle of the upper rotating member.

[0010] Furthermore, the beveled tooth surfaces of the second end gear are arranged in the same direction, that is, for the multiple gears that make up the second end gear, their beveled tooth surfaces are all arranged circumferentially clockwise or all arranged circumferentially counterclockwise. In this way, during the process of driving the upper rotating member to rotate circumferentially, it rotates in the same direction, ensuring the alternating completion of the up and down axial positions of the upper rotating member.

[0011] Further, a transparent cover is provided on the upper end of the upper pen barrel and located outside the IP decoration piece; with this structure, the IP decoration piece is protected by the transparent cover to avoid being damaged by contact; at the same time, the transparent structure can also fully present the visual changes of the internal IP decoration piece, thereby providing a user with a brand-new visual change presentation effect.

[0012] Further, the second actuating assembly includes an actuating rod, a lower rotating member, and a second guide rail located on the inner wall of the pen barrel. The actuating rod is slidably sleeved in the upper rotating member and can follow the upper rotating member downward to abut against the lower rotating member. A second wall gear is provided on the outer wall of the lower rotating member, and the second wall gear is slidably engaged or abutted with the second guide rail; the lower rotating member also abuts against the pen refill, and the lower end position of the pen refill abuts against a second elastic member; with the above structure, when the first actuating assembly drives the actuating rod to push the lower rotating member downward, the lower rotating member realizes the pushing and retracting actions of the pen refill through the cooperation among the second elastic member, the second wall gear, and the second guide rail, so as to realize the pressing and actuating of the pen refill; moreover, the second actuating assembly realizes an associated action with the first actuating assembly through the actuating rod, thereby realizing the synchronous driving of the pen refill and the IP decoration piece.

[0013] Further, a third end gear capable of abutting against the second wall gear is provided on the actuating rod. Both sides of the tooth tip of the third end gear are provided with inclined tooth surfaces. The second guide rail includes a second tooth groove and a second groove wall. The end of the second groove wall is provided with a third guiding surface and a fourth guiding surface. The third guiding surface and the fourth guiding surface are respectively located on both sides of the second tooth groove. The third guiding surface is used to guide the second wall gear into the second tooth groove, and the fourth guiding surface is used to guide the inclined tooth surface of the second wall gear to abut against it; with the above structure, when the actuating rod is driven by the first actuating assembly to move downward, during the process of the end gear abutting against and retracting from the second wall gear, it can drive the completion of the telescopic action of the pen refill.

[0014] Further, a convex block is provided on the outer wall of the actuating rod that is slidably engaged with the second guide rail, and the convex block is slidably engaged in the second tooth groove; with this structure, through the sliding cooperation between the convex block and the second tooth groove, the actuating rod axially slides in the second guide rail without circumferential rotation, so as to maintain an effective drive for the lower rotating member.

[0015] Further, a first positioning rib is provided on the outer wall of the upper rod inner lining, and a first sliding groove for sliding cooperation therewith is provided on the inner wall of the corresponding upper pen barrel; with this structure, after the upper rod inner lining is sleeved in the upper pen barrel, the positioning rib slides in the first sliding groove, so that the upper rod inner lining will not rotate circumferentially and maintains an effective cooperation with the upper rotating member.

[0016] Furthermore, second positioning ribs are provided on the outer wall of the upper rotating member, and correspondingly, second sliding grooves for sliding cooperation therewith are provided on the inner wall of the IP decorative member; with this structure, after the IP decorative member is sleeved in the second sliding groove, its second positioning ribs slide in the second sliding groove, enabling the IP decorative member to rotate circumferentially synchronously with the upper rotating member to achieve the presentation effect of rotating the IP decorative member at different angles.

[0017] Furthermore, the first tooth groove and the second tooth groove are axially aligned with each other, and the first guiding surface and the second guiding surface on both sides of the first tooth groove are opposite in orientation to the third guiding surface and the fourth guiding surface on both sides of the second tooth groove; that is, the upper and lower guide rails of the present application are circumferentially corresponding and the tooth grooves are aligned. And if the left side of the first tooth groove is the first guiding surface and the right side is the second guiding surface, then the left side of the corresponding second tooth groove is provided with the fourth guiding surface and the right side is provided with the third guiding surface. Such a setting can ensure that during the operation of the two sets of flipping members, the IP decorative member and the pen core move in and out (contract into the pen barrel 1 and extend out beyond both ends of the pen barrel) bidirectionally in the same way.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] As shown in the appendix Figure 1-17 As shown, a two-way moving writing instrument of the present application includes a pen barrel 1, an IP decoration 2, a slider 3, a refill 4, a first flipping component a1 and a second flipping component a2 located inside the pen barrel 1; the IP decoration 2 and the slider 3 are connected to the first flipping component a1, and the first flipping component a1 is used to drive the IP decoration 2 to move up and down and rotate circumferentially; the second flipping component a2 is located below the first flipping component a1 and is linked with the first flipping component a1; when the first flipping component a1 moves up and down, it drives the second flipping component a2 to drive the refill 4 to extend or retract relative to the pen barrel 1; specifically, two sets of flipping components are provided in one writing instrument of the present application, where the first flipping component a1 is located at the upper part of the writing instrument and the second flipping component a2 is located at the lower part of the writing instrument, and the two sets of flipping components can be linked; the first flipping component a1 is used to drive the circumferential rotation and axial up-and-down position change of the IP decoration 2; and the second flipping component a2 is similar in structure to the flipping component of a traditional flipping writing instrument, both of which are for driving the nib of the refill 4 to extend or retract relative to the front end of the pen barrel 1; for the first time, the present application realizes the driving of different components by setting two sets of flipping components, upper and lower, in one writing instrument, so that the IP decoration 2 and the telescoping of the nib on the writing instrument achieve a synchronous linkage effect, endowing the writing instrument with a new visual presentation effect to meet different usage requirements.

[0039] With the above structure, two sets of actuating components are provided inside the pen barrel in this application, and the two sets of actuating components are associated with each other to achieve interlocking. The first actuating component can achieve axial up-and-down driving and circumferential rotation of the IP decorative part, so that the structure of the IP decorative part can present different positions and angles, realizing the visual transformation effect of the writing instrument, thus meeting the needs of different users for the shape and visual transformation of the writing instrument; while the second set of actuating components still undertakes the driving function of the pen refill, realizing the extension and contraction actions of the pen refill to meet the functional requirements of existing retractable writing instruments or pressing writing instruments; moreover, the first actuating component and the second actuating component are associated and interlocked with each other, and the second actuating component can be driven during the operation of the first actuating component. Therefore, in one writing instrument, the IP decorative part and the pen refill can move in and out in both directions simultaneously, and at the same time, the axial up-and-down position and circumferential rotation changes of the IP decorative part are realized, achieving the technical effect that the visual effects of the extension and contraction function of the pen refill and the angle and position changes of the IP decorative part can be presented synchronously.

[0040] As shown in the Figure 2-4 , Figure 6-9 drawing, the first actuating component a1 described in this application includes an upper rod lining 5 located inside the upper pen barrel 101, and a first guide rail 501 is provided on the inner wall of the upper rod lining 5; an upper rotating member 6 fixedly connected to the IP decorative part 2, the slider 3 is arranged between the IP decorative part 2 and the upper rotating member 6, and the slider 3 is driven to move up and down by the pen clip 7, a first wall gear 601 is provided on the outer wall of the upper rotating member 6, and a first end gear 602 is provided at the lower end of the upper rotating member 6; a second end gear 102 located inside the upper pen barrel 101, the first end gear 602 and the second end gear 102 are arranged opposite to each other, and a first elastic member 8 is provided between the upper rotating member 6 and the end wall of the second end gear 102; with this structure, the overall structure of the first actuating component a1 is formed. When the pen clip 7 drives the slider 3 to move downward, the first elastic member 8 is compressed. At this time, the slider 3 abuts against the upper rotating member 6 and also moves downward. The first wall gear 601 slides in the first guide rail 501, and then gradually the first end gear 602 meshes with the second end gear 102 to achieve circumferential driving of the upper rotating member 6, so that the upper rotating member 6 is located in the tracks of different first guide rails 501, thereby realizing the change of the upper and lower positions in the axial direction. During this process, since the IP decorative part 1 and the upper rotating member 6 are fixedly connected to each other, the IP decorative part 2 also realizes the change of the axial up-and-down position and the circumferential angle change, giving users different visual presentation effects.

[0041] As an example, a transparent cover 9 is provided on the outer side of the upper end of the upper pen barrel 101 described in the present application; specifically, the transparent cover 9 is in interference fit with the pen barrel 1 to achieve a tight connection; with this structure, the IP decoration 2 is protected by the transparent cover 9 to avoid being damaged by touching; at the same time, the transparent structure can also fully present the visual changes of the internal IP decoration, so as to provide a user with a brand-new visual change presentation effect.

[0042] As shown in the Figure 2-16 accompanying drawings, chamfered surfaces 10 are provided on both sides of the tooth tips of the teeth of the first end gear 602 described in the present application, and a chamfered surface 10 is provided on one side of the tooth tip of the corresponding second end gear 102, and the other side is a vertical tooth surface 11; that is, the structure of the second end gear 102 is similar to the ratchet tooth structure of a ratchet, and the end gears are both a ring gear structure composed of a plurality of teeth arranged circumferentially; with this structure, when the first end gear 602 contacts the second end gear 102, due to the setting of the tooth surfaces as described above, when the upper rotating member 6 is compressed, it can be driven to rotate circumferentially under the guidance of the chamfered surface 10 of the second end gear 102. When the first elastic member 8 returns and extends after no longer pressing, the upper rotating member 6 is pushed up again, and the mating position between the first wall gear 601 on its outer peripheral wall and the first guide rail 501 also changes, so as to realize different mating of the axial positions of the upper rotating member 6 and the first guide rail 501, and realize the circumferential and axial position changes of the upper rotating member 6 and the IP decoration 2 thereon; the above structure is similar to the telescopic principle of the existing flip pen. Through the cooperation of the elastic member, the guide rail, the end gear and the wall gear, the circumferential rotation and the axial up and down position changes of the upper rotating member 6 are realized, so as to realize the change of the visual presentation effect of the IP decoration 2.

[0043] As shown in the Figure 10 , Figure 14-17 accompanying drawings, chamfered surfaces 10 inclined on one side are provided at the end of each tooth of the first wall gear tooth 601 close to the IP decoration 2. The first guide rail 501 includes a first tooth groove 502 and a first groove wall 503. First guide surfaces 504 and second guide surfaces 505 are provided at the end of the first groove wall 503. The first guide surfaces 504 and second guide surfaces 505 are respectively located on both sides of the first tooth groove 502. The first guide surface 504 is used to guide the first wall gear 601 into the first tooth groove 502 (at this time, as shown in Figure 1-4 the accompanying drawings, the upper rotating member 6 and the IP decoration 2 are close to the upper end of the pen barrel 1 and are at a high position, and the IP decoration 2 can be effectively presented through the transparent cover 9, and the first elastic member 8 extends), and the second guide surface 505 is used to guide the chamfered surface 10 of the first wall gear 601 to abut against it (at this time, as shown in the Figure 5-7As shown, the upper rotating member 6 and the IP decorative member 2 are away from the upper end of the pen barrel 1 and located at the low points, and the first elastic member 8 is compressed); with this structure, when the upper rotating member 6 rotates circumferentially, according to the mutual cooperation of the above-mentioned guiding surface, the tooth groove, and the helical surface 10, when the first wall gear 601 is located in the first tooth groove 502, the upper rotating member 6 is located at the first axial position point (high point, closer to the upper end of the pen barrel 1), and at this time, the IP decorative member 2 is located at the axial high point; when the helical surface 10 of the first wall gear 601 abuts against the second guiding surface 505, the upper rotating member 6 is located at the second axial position point (low point, that is, moving downward, slightly away from the upper end of the pen barrel 1), and at this time, the IP decorative member 2 is located at the axial low point; by repeatedly pressing, the change of the IP decorative member 2 at two axial position points is realized, and at the same time, the circumferential angle of the IP decorative member 2 also changes during this process.

[0044] As an example, the tooth tips of the first end gear 602 and the second end gear 102 described in the present application are misaligned with each other; with this structure, that is, the axial connection lines of the tooth tips of the two sets of end gears are not completely aligned with each other, but are misaligned. In the process of the first end gear and the second end gear 102 abutting, such a structure can guide the helical surface 10 of the end gear of the upper rotating member 6 along the helical surface 10 of the second end gear 102 through this misalignment, ensuring the stable change of the circumferential angle of the upper rotating member 6 and preventing the upper rotating member 6 from being stuck during the circumferential rotation process.

[0045] As attached Figure 14-17 As shown, the helical surfaces 10 of the second end gear 102 described in the present application are arranged in the same direction, that is, for the multiple gears constituting the second end gear 102, their helical surfaces 10 are all arranged circumferentially clockwise or all arranged circumferentially counterclockwise. In this way, during the process of driving the upper rotating member 6 to rotate circumferentially, it rotates in the same direction, ensuring the alternation of the upper and lower axial positions of the upper rotating member 6.

[0046] As attached Figure 2-4 , Figure 6-9As described above, the second actuating assembly a2 of the present application includes an actuating rod 12, a lower rotating member (runner) 13, and a second guide rail 103 located inside the pen barrel 1. The actuating rod 12 is slidably sleeved in the upper rotating member 6 and can follow the downward movement of the upper rotating member 6 to abut against the lower rotating member 13. A second wall gear 1301 is provided on the outer wall of the lower rotating member 13, and the second wall gear 1301 is slidably engaged or abutted with the second guide rail 103; the lower rotating member 13 also abuts against the pen refill 4, and the lower end position of the pen refill 4 abuts against the second elastic member 14; with the above structure, when the first actuating assembly a1 moves downward to drive the actuating rod 12 to push against the lower rotating member 13, the lower rotating member 13 realizes the pushing and retracting actions of the pen refill 4 through the cooperation between the second elastic member 14, the second wall gear 1301, and the second guide rail 103, realizing the pressing and actuating of the pen refill 4; moreover, the second actuating assembly a2 realizes an associated action with the first actuating assembly a1 through the actuating rod 12, thereby realizing the synchronous driving of the pen refill 4 and the IP decoration member 2; the structure and operating principle of the second actuating assembly a2 of the present application can be similar to the actuating structure and actuating principle of existing actuating pens, and any structure that can realize the actuating of the pen refill can replace the structure of the second actuating assembly of the present application.

[0047] As shown in the attached Figure 8-9 and Figure 11 , Figure 14-17 figures, a third end gear 1201 capable of abutting against the second wall gear 1301 is provided on the actuating rod 12 of the present application. Both sides of the tooth tip of the third end gear 1201 are provided with helical tooth surfaces 10. The second guide rail 103 includes a second tooth groove 104 and a second groove wall 105. The end of the second groove wall 104 is provided with a third guiding surface 106 and a fourth guiding surface 107. The third guiding surface 106 and the fourth guiding surface 107 are respectively located on both sides of the second tooth groove 104. The third guiding surface 106 is used to guide the second wall gear 1301 into the second tooth groove 104 (at this time, as shown in the attached Figure 5-7 figures, the pen tip retracts), and the fourth guiding surface 107 is used to guide the helical tooth surface 10 of the second wall gear 1301 to abut against it (at this time, as shown in the attached Figure 1-4 figures, the pen tip extends); with the above structure, when the actuating rod 12 moves downward under the drive of the first actuating assembly a1, causing its end gear to abut against and retract from the second wall gear 1301, the telescopic action of the pen refill 4 can be driven to be completed.

[0048] As shown in the attached Figure 9-11, a bump 1202 is provided on the outer wall of the lifting rod 12 that is slidably engaged with the second guide rail 103, and the bump 1202 is slidably engaged in the second tooth groove 104; with this structure, through the sliding engagement of the bump 1202 and the second tooth groove 104, the lifting rod 12 axially slides in the second guide rail 103 without circumferential rotation, so as to maintain effective driving of the lower rotating member 13.

[0049] As shown in the appendix Figure 13-14 , a first positioning rib 506 is provided on the outer wall of the upper rod lining 5 of the present application, and a first sliding groove 108 that is slidably engaged therewith is provided on the inner wall of the corresponding upper pen rod 101; specifically, the first positioning rib 506 axially extends on the outer wall of the upper rod lining 5, and the first sliding groove 108 also axially extends to match it; with this structure, after the upper rod lining 5 is sleeved in the upper pen rod 101, its first positioning rib 506 is slidably engaged in the first sliding groove 108, so that the upper rod lining 5 does not rotate circumferentially, maintaining its effective cooperation with the upper rotating member 6.

[0050] As shown in the appendix Figure 10 , Figure 15-17 , a second positioning rib 603 is provided on the outer wall of the upper rotating member 6 of the present application, and a second sliding groove 201 that is slidably engaged therewith is provided on the inner wall of the corresponding IP decorative member 2; with this structure, after the IP decorative member 2 is sleeved in the second sliding groove 201, its second positioning rib 603 is slidably engaged in the second sliding groove 201, so that the IP decorative member 2 can rotate circumferentially synchronously with the upper rotating member 6, so as to achieve the presentation effect of the IP decorative member 2 rotating at different angles, and avoid circumferential slipping between the two, which affects the visual presentation effect of the IP decorative member 2.

[0051] As shown in the appendix Figure 15-17As shown, the first tooth groove 502 and the second tooth groove 104 described in the present application are axially aligned with each other, and the first guide surface 504 and the second guide surface 505 provided on both sides of the first tooth groove 502 are opposite in orientation to the third guide surface 106 and the fourth guide surface 107 provided on both sides of the second tooth groove 104; that is, the upper and lower guide rails of the present application are circumferentially corresponding to each other and the tooth grooves are aligned. And if the left side of the first tooth groove 502 is the first guide surface 504 and the right side is the second guide surface 505, then the left side of the corresponding second tooth groove 104 is provided with the fourth guide surface 107 and the right side is provided with the third guide surface 106. In this way, when the first wall gear on the outer wall of the upper rotating member 6 enters the first tooth groove 502 and the IP decoration member 2 is located at the high position point, the end inclined tooth surface 10 of the second wall gear 1301 of the corresponding lower rotating member 13 abuts against the fourth guide surface 107 so that the refill 4 is in the extended state. Conversely, when the IP decoration member 2 is located at the low position point, the corresponding refill 4 is in the retracted state; thus, it can be ensured that during the operation of the two groups of flipping members, the IP decoration member 2 and the refill 4 move in and out (retract into the pen barrel 1) and out (extend beyond both ends of the pen barrel 1) bidirectionally.

[0052] It should be noted that, as shown in the attached Figure 2-4 Figures 6 - 9, the upper end of the flipping rod 12 of the present application can be provided with a guide post, and an axially oriented guide hole is provided in the corresponding upper rotating member 6 to achieve sliding fit between the two; the upper end of the lower rotating member 13 of the present application is provided with a guide post, and an axially oriented guide hole is provided in the flipping rod 12 to achieve sliding fit between the two; with this structure, the circumferential rotation of the lower rotating member 13 does not affect the operation of the flipping rod 12, and the flipping rod 12 always maintains axial up and down sliding; as shown in the attached Figure 8-9 Figure, the pen barrel 1 of the present application can be divided into an upper pen barrel 101 and a lower pen barrel 109. A lower barrel lining 110 is also sleeved in the lower pen barrel 109. An external thread is provided on the outer part of the upper end of the lower barrel lining 110, and an internal thread is provided on the inner wall of the upper pen barrel 101. The two are connected by threads. A step surface is provided at the lower end position of the refill 4 of the present application to limit the second elastic member 14 between the refill 4 and the lower end head of the pen barrel 1; the second end gear 102 of the present application is provided below the upper barrel lining 5, and its radial step surface can abut against the upper barrel lining 5; in addition, the step surface of the third end gear 1201 of the flipping rod 12 is located below the radial step surface; the pen clip 7 of the present application is connected to the slider 3 (as shown in Figure 8-9 Figure, a jack can be provided on the slider 3, and a plug-in block can be provided on the corresponding pen clip 7. The pen clip 7 is connected by inserting the plug-in block into the jack), and when the pen clip 7 is pressed, the slider 3 can be driven to drive the two groups of flipping components to operate; as shown in the attached Figure 17As shown, the first tooth grooves 502 and the first groove walls 503 provided on the first guide rail 501 of the present application are arranged in multiple groups along the circumferential direction according to a rule, so that the upper rotating member 6 can achieve an equal-angle rotation once within the structure of the first guide rail 501 with this rule, such as a 45-degree rotation each time; similarly, the second tooth grooves 104 and the second groove walls 105 on the second guide rail 103 of the present application are also arranged in multiple groups along the circumferential direction according to a rule, so that the lower rotating member 13 can achieve an equal-angle rotation once within the structure of the first guide rail 501 with this rule, such as a 45-degree rotation each time; a end gear can also be provided on the upper end surface near the lower rotating member 13 of the present application, and any structure that does not affect the circumferential angle rotation of the lower rotating member 13 by the lifting rod 12 is acceptable; the first elastic member 8 and the second elastic member 14 adopted in the present application can be the conventional straight spring structures used in writing utensils; the IP decoration member 2 of the present application is as attached Figure 2-4 , Figure 6-7 shown, can be a heart structure, or other deformations such as small animals or other structures, and its color can also have various changes, which can be specifically adjusted according to the development type or market demand. These deformations all belong to the changes within the protection scope of the structure of the IP decoration member 2 described in the present application; protrusions can be provided on the outer wall of the upper end of the lifting rod 12 of the present application, and axially extending chutes can be provided on the inner wall of the corresponding upper rotating member 6 that fits with it. By deforming, the protrusions can cross the inner wall and enter the chutes, so as to form a buckling structure between the lifting rod 12 and the upper rotating member 6. When the first lifting assembly a1 is pressed and lowered to a certain distance, it can push the lifting rod 12 downward, and when the pressing force is removed and the first elastic member 8 extends to push up the upper rotating member 6, the lifting rod 12 can be driven to move upward through the above buckling structure, and this buckling structure does not affect the axial sliding between the lifting rod 12 and the upper rotating member 6.

[0053] The specific operating principle of this writing utensil of the present application is as follows: Through the structure attached Figure 1-16 shown, the writing utensil of the present application containing two sets of lifting assemblies is assembled; when the pen clip is pressed, the pen clip moves downward and synchronously drives the slider to abut against the upper rotating member and move downward; when the lower end of the light guide moves a certain distance, the upper rotating member will contact the lifting rod and continue to move downward together; when the lifting rod moves to a certain distance, it will drive the lower rotating member to move downward and rotate, achieving the effect of lifting the pen core; at the same time, the upper rotating member abuts against the second end gear, thereby driving the circumferential rotation of the upper rotating member to achieve the upper lifting effect; the lifting of the upper rotating member will drive the IP decoration member to rotate at an angle (such as rotating 45 degrees each time); in the above pressing and lifting process, the final effect is that when the pen core comes out, the IP decoration member rises to a high position, such as Figure 1-4 shown state; when the pen core retracts, the IP decoration member drops to a low position, such as Figure 5-7In the shown state, each time the IP decoration part comes out, there will be a change in the circumferential rotation angle of 90 degrees; during the above-mentioned core ejection and core retraction processes, the upper rotating part can control the axial up and down positions within the upper rod lining; after the above-mentioned assembly is completed: for the writing instrument of the present application, when the pen clip is pressed to eject the core, the IP decoration part will move in and out bidirectionally with the pen core (that is, as shown in the appendix Figure 1-4 When the tip of the pen core extends out of the front end of the pen barrel, the corresponding IP decoration part also extends upward to the high position; as shown in the appendix Figure 5-7 When the tip of the pen core retracts into the front end of the pen barrel, the corresponding IP decoration part also retracts downward to the low position; the above state is the bidirectional movement described in the present application), and at the same time, the position rotation change of the IP decoration part is realized, so that the visual effects of the pen core telescopic function, the circumferential rotation of the IP decoration part, and the up and down axial changes are presented synchronously.
