Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] In related technologies, the correction tool is directly integrated into the pen. When it is necessary to adjust the extension or retraction of the pen tip inside the pen barrel, the correction tool must be disassembled before adjustment can be made.

[0026] To address the aforementioned issues, this embodiment adjusts the extension or retraction of the pen tip by rotating the outer shell of the correction tool relative to the pen barrel 110, thereby improving the convenience of adjusting the extension or retraction of the pen tip inside the pen barrel.

[0027] The following describes in detail, with reference to the accompanying drawings, the specific structure of a pen 1 with a correction tool provided by this utility model embodiment and the corresponding technical effects it brings.

[0028] Please refer to Figures 1-5 This utility model provides a pen 1 with a correction tool, including a pen 100 and a correction tool 200. The pen 100 includes a pen barrel 110, a pen core 120, and an elastic element 130. The pen core 120 and the elastic element 130 are installed on the pen barrel 110. The pen core 120 has a first boss at one end near the pen tip. The pen barrel 110 includes a first end and a second end that are axially opposite each other. The two ends of the elastic element 130 abut against the first boss and the inner cavity of the pen barrel 110, respectively. The first end has an opening 111 for the pen tip of the pen core 120 to extend out. The correction tool 200 includes a housing 210 and a correction element 220. The correction element 220 is installed inside the housing 210. The housing 210 is detachably connected to the second end and can rotate relative to the pen barrel 110. During the rotation of the housing 210 relative to the pen barrel 110, it can drive the pen tip of the pen core 120 to extend out of the opening 111 or retract into the pen barrel 110.

[0029] In this embodiment, when it is necessary to adjust the extension or retraction of the pen inside the pen barrel 110, the user can rotate the outer shell 210 of the correction tool 200 relative to the pen barrel 110 to drive the pen tip of the pen core 120 to extend out of the opening 111 or retract into the pen barrel 110, which improves the integration of the pen 100 and the correction tool 200 and also makes it easier for the user to adjust the pen core 120 inside the pen barrel 110.

[0030] It should be noted that the correction tool 200 in this embodiment can be a correction tape, and the elastic element 130 in this embodiment can be a spring.

[0031] In detail, in this embodiment, the lower end of the outer shell 210 is connected to a threaded connector 230, the outer peripheral wall of the threaded connector 230 is provided with an external thread, and the second end is provided with an internal thread that connects with the threaded connector 230.

[0032] In other words, during the threaded connection between the housing 210 of the correction tool 200 and the pen barrel 110, not only can the housing be fixed to the pen barrel 110, but the extension or retraction of the pen tip 120 inside the pen barrel 110 can also be adjusted. When the housing 210 is rotated and fixed relative to the pen barrel 110, the pen tip 120 inside the pen barrel 110 can be extended out of the pen barrel 110. That is, by rotating the pen barrel 110 in the direction in which the pen tip 120 is extended, the pen barrel 110 and the housing 210 of the correction tool 200 can be tightened.

[0033] When it is necessary to retract the pen refill 120 into the pen barrel 110, the outer casing 210 can be rotated in the direction of disconnecting the outer casing 210 from the pen barrel 110. It should be noted that in this embodiment, when the pen refill 120 is fully retracted into the pen barrel 110, the pen barrel 110 is still threadedly connected to the outer casing 210. When it is necessary to disconnect the pen barrel 110 from the outer casing 210, the outer casing 210 can be rotated in the direction of disconnection to separate the outer casing 210 from the pen barrel 110, thereby replacing the pen refill 120.

[0034] During this process, by rotating the outer shell 210 relative to the pen barrel 110, the extension and retraction of the pen tip 120 and the change of the connection state between the outer shell 210 and the pen barrel 110 are adjusted, effectively improving the adjustment efficiency of the pen tip 120. This also maintains the overall structural weight from becoming excessive, ensuring a good user experience.

[0035] Please refer to Figures 2-5 , Figure 6 , Figures 8-9 In detail, the pen 1 with correction tools also includes a sliding post 240. The outer periphery of the sliding post 240 is provided with a first mating part 241 extending axially. The outer periphery of the sliding post 240 is also provided with a cam part 242 extending axially. The threaded connector 230 is hollow cylindrical. The inner cavity of the threaded connector 230 is provided with a second mating part 231 extending axially. The sliding post 240 is installed in the threaded connector 230 and the first mating part 241 and the second mating part 231 slide in engagement. The sliding post 240 can rotate with the threaded connector 230. The outer shell 210 is provided with a mating protrusion 2114 that slides in engagement with the cam part 242. The two ends of the sliding post 240 along the axial direction abut against the pen core 120 and the mating protrusion 2114, respectively.

[0036] In detail, in this embodiment, the first mating part 241 is a convex strip extending along the axial direction, and the second mating part 231 is a sliding groove.

[0037] By cooperating with the protrusion 2114 and the cam portion 242, during the tightening of the outer shell 210 and the pen barrel 110, the sliding column 240 can press down the pen core 120 to overcome the elastic force of the elastic member 130 and extend the pen core 120 out of the opening 111 of the pen barrel 110.

[0038] Specifically, the cam part 242 is a cam guide groove, which extends circumferentially along the sliding column 240. Along the first preset direction, the axial distance between the cam guide groove and the pen refill 120 gradually increases. The cam guide groove has a first stop point 2421 and a second stop point 2422. Along the second preset direction, the side of the first stop point 2421 away from the second stop point 2422 has a first stop surface 2423. Along the first preset direction, the side of the second stop point 2422 away from the first stop point 2421 has a second stop surface 2424. The axial distance between the first stop point 2421 and the pen refill 120 is smaller than the distance between the second stop point 2422 and the pen refill 120. During the process of the cooperating protrusion 2114 moving from the first stop point 2421 to the second stop point 2422 along the first preset direction, the pen refill 120 extends out of the pen barrel 110. Both the first preset direction and the second preset direction are parallel to the circumferential direction of the sliding column 240, and the first preset direction and the second preset direction are opposite.

[0039] It should be noted that in this embodiment, both the first preset direction and the second preset direction are perpendicular to the axial direction. When the mating protrusion 2114 abuts against the first stop point 2421, the pen lead 120 is located inside the pen barrel 110 and does not protrude from the opening 111. When the mating protrusion 2114 abuts against the second stop point 2422, the pen lead 120 protrudes from the pen barrel 110.

[0040] Understandably, during the movement of the mating protrusion 2114 along the second preset direction on the cam guide groove, and when the mating protrusion 2114 reaches the first stop point 2421, the first stop surface 2423 can restrict the mating protrusion 2114 from continuing to move along the second preset direction on the cam guide groove. During the movement of the mating protrusion 2114 along the first preset direction on the cam guide groove, and when the mating protrusion 2114 reaches the second stop point 2422, the second stop surface 2424 can restrict the mating protrusion 2114 from continuing to move along the first preset direction on the cam guide groove.

[0041] Optionally, in some embodiments, the threaded connector 230 is detachably connected to the housing 210. If the threaded connector 230 is damaged, it is not necessary to replace the entire housing 210; only the threaded connector 230 needs to be replaced, thus saving costs.

[0042] Please refer to Figure 6 and Figure 8In detail, in this embodiment, the threaded connector 230 is engaged with the outer shell 210. For example, the outer peripheral wall of the threaded connector 230 is provided with a engaging protrusion 232, and the inner cavity of the outer shell 210 is provided with a connecting groove 2115 that engages with the engaging protrusion 232.

[0043] In this embodiment, the snap-fit ​​protrusion 232 is an annular protrusion and there are two of them. The two snap-fit ​​protrusions 232 are arranged at intervals along the axial direction of the threaded connector 230. Similarly, the snap-fit ​​groove is also an annular snap-fit ​​groove that cooperates with the snap-fit ​​protrusion 232. The number of connecting snap-fit ​​grooves 2115 is the same as the number of snap-fit ​​protrusions 232. Through the snap-fit ​​protrusions 232 and the connecting snap-fit ​​grooves 2115, the threaded connector 230 and the outer shell 210 can be limited in the axial and radial directions, so that the threaded connector 230 is fixedly connected to the outer shell 210.

[0044] Of course, in some other alternative embodiments, the threaded connector 230 and the housing 210 can also be connected by screws.

[0045] Alternatively, in some other optional embodiments, the threaded connector 230 and the housing 210 are integrally formed, that is, the threaded connector 230 and the housing 210 are integrally formed and located at the lower end of the housing 210, which ensures the connection strength between the threaded connector 230 and the housing 210.

[0046] Please refer to Figures 5-7 In detail, in this embodiment, the outer shell 210 includes a bottom shell 211 and a front shell 212. The bottom shell 211 and the front shell 212 are detachably connected and together define the installation space of the mounting correction component 220. The end of the front shell 212 away from the bottom shell 211 is provided with an opening 2121, which exposes the nozzle 221 of the correction component 220.

[0047] Understandably, since the outer casing 210 includes a detachably connected bottom casing 211 and a front casing 212, specifically, the bottom casing 211 and the front casing 212 are arranged sequentially along the axial direction. In this embodiment, the bottom casing 211 is connected to the front casing 212 via a correction element 220. After the bottom casing 211 and the front casing 212 are disassembled, it is convenient for the user to replace the correction tape. Since the opening 2121 exposes the pressure tip 221 of the correction tape, it is convenient for the user to correct any writing errors.

[0048] In this embodiment, the bottom shell 211 and the correction component 220 are detachably connected. That is, the correction component 220 can be fixedly installed on the bottom shell 211, and it is also convenient for the user to replace it when it is necessary to replace the correction component 220.

[0049] Specifically, in this embodiment, the correction member 220 is engaged with the bottom shell 211. The outer peripheral wall of the correction member 220 is provided with a first engagement protrusion 222, and the inner cavity of the bottom shell 211 is provided with a first engagement groove 2112 that engages with the first engagement protrusion 222. The first engagement groove 2112 is closer to the front shell 212 than the first connecting groove 2115.

[0050] To enhance the connection stability between the corrector 220 and the housing 210 and ensure that the corrector 220 is stably installed inside the housing 210, the corrector 220 is also detachably connected to the front housing 212. In other words, the corrector 220 is not only fixedly connected to the front housing 212, but also allows the user to easily separate the front housing 212 from the corrector 220.

[0051] In detail, the front shell 212 is engaged with the correction part 220. Specifically, the outer peripheral wall of the correction part 220 is also provided with a second mating protrusion 223. The second mating protrusion 223 is away from the bottom shell 211 relative to the first mating protrusion 222. The inner cavity of the front shell 212 is provided with a second mating groove 2122 that engages with the second mating protrusion 223.

[0052] In other words, in this embodiment, after the bottom shell 211 is engaged with the first mating protrusion 222 and the front shell 212 is engaged with the second mating protrusion 223, the bottom shell 211 and the front shell 212 can be engaged by the correction member 220.

[0053] Specifically, the aforementioned threaded connector 230 is detachably connected to the bottom shell 211. The inner cavity of the bottom shell 211 is provided with a connecting groove 2115, and the aforementioned mating protrusion 2114 is provided inside the bottom shell 211.

[0054] Of course, please refer to Figure 11 In some other embodiments, the bottom shell 211 has two slots 2111 spaced apart along a first direction, and the front shell 212 has two elastic arms spaced apart at one end near the bottom shell 211. The elastic arms 2123 are provided with hooks 2124 that engage with the slots 2111. The bottom shell 211 has a notch 2113 that exposes at least a portion of the elastic arms 2123. The two elastic arms 2123 can retract in the first direction to release the engagement between the slots 2111 and the hooks 2124.

[0055] Understandably, with the elastic arm 2123 provided and the bottom shell 211 provided with a notch 2113 for at least part of the elastic arm 2123 to be exposed, when it is necessary to disassemble the front shell 212 and the bottom shell 211, the user can easily press the elastic arm 2123 through the notch 2113 to make the two elastic arms 2123 retract in the first direction, thereby causing the hook 2124 to disengage from the locking hole 2111, thereby disassembling the front shell 212 and the bottom shell 211. In this embodiment, the corrector 220 can be installed in the installation space jointly defined by the bottom shell 211 and the front shell 212, and does not need to be snapped with the bottom shell 211 and the front shell 212. Of course, in order to ensure the stability of the corrector 220 in the installation space, the corrector 220 can also be snapped with the bottom shell 211 and / or the front shell 212.

[0056] To facilitate user pressing, a pressing protrusion 2125 is provided on the opposite side wall of the two elastic arms 2123, with the pressing protrusion 2125 exposing the notch 2113.

[0057] Please refer to Figure 10 The front cover 212 is provided with a protective cover 213 at the end away from the bottom cover 211. The protective cover 213 is hinged to the front cover 212. The protective cover 213 can rotate relative to the front cover 212 to close or open the opening 2121. By providing the protective cover 213, the nozzle 221 of the correction tape can be prevented from being exposed. When the correction tape needs to be used, the user can rotate the protective cover 213 to open the opening 2121.

[0058] Please continue to refer to this. Figures 2-4 In this embodiment, in order to improve the stability of the user's writing and ensure that the center of gravity of the pen 1 with correction tool in this embodiment is relatively low, a counterweight 140 is also provided in the pen barrel 110 in this embodiment. The counterweight 140 is provided with a through hole for the pen core 120 and the elastic element 130 to pass through.

[0059] In other words, by setting the counterweight 140, the center of the entire structure can be adjusted to avoid the center of gravity shifting upward due to the correction tool 200, which would affect the writing experience.

[0060] In summary, this utility model embodiment provides a pen 1 with a correction tool, including a pen 100 and a correction tool 200. The pen 100 includes a pen barrel 110, a pen refill 120, and an elastic element 130. The pen refill 120 and the elastic element 130 are installed in the pen barrel 110. The pen refill 120 has a first protrusion at one end near the pen tip. The pen barrel 110 includes a first end and a second end that are axially opposite each other. The two ends of the elastic element 130 abut against the first protrusion and the inner cavity of the pen barrel 110, respectively. The first end has an opening 111 for the pen tip of the pen refill 120 to extend out. The correction tool 200 includes a housing 210 and a correction element 220. The correction element 220 is installed in the housing 210. The housing 210 is detachably connected to the second end and can rotate relative to the pen barrel 110. During the rotation of the housing 210 relative to the pen barrel 110, the pen tip of the pen refill 120 can be driven to extend out of the opening 111 or retract into the pen barrel 110, which facilitates the user to adjust the pen refill 120 in the pen barrel 110.

[0061] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
