Description

Technical Field

[0001] This invention relates to a pen, and more particularly to a lift pen. Background Technology

[0002] As times change and development progresses, lifting techniques are gradually replacing pressing techniques. The convenience of lifting compared to pressing is undeniable. However, the emergence of entirely new operating concepts often necessitates continuous evolution. While constantly optimizing and improving traditional lifting structures, it is also crucial to enrich the other possibilities of lifting design. Only in this way can a better and more robust lifting technique market be formed. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing lifting methods being too simple and costly, and to provide a lifting pen that is less expensive and can be used for side pressing and / or rotating to retract the core and / or pushing the ring to retract the core and / or rotating to self-lock and / or pulling out the core.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution: A pull-out pen includes a retractable writing sleeve, a refill, and a refill spring. The writing sleeve includes a lower sleeve and an upper sleeve that are interlocked with each other; The pen refill is located inside the writing sleeve; the refill spring is located between the pen refill and the writing sleeve. By extending and retracting the writing sleeve, the pen refill can have two positional changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part and a limiting part; when the execution part is located on the upper sleeve, the limiting part is located on the lower sleeve, and vice versa. When the lead is ejected, the actuator moves to the limiting part, which restricts the writing end of the lead to remain exposed on the writing sleeve. When the pen retracts, the actuator and the limiting part separate, and the writing end of the pen retracts completely into the writing sleeve.

[0005] As a preferred embodiment of the present invention, the writing sleeve is further provided with one or more release components, which are used to indirectly or directly cause the actuating part and the limiting part to separate; when multiple release components are provided at the same time, the release components will adopt different forms, so that multiple different release and core-retracting effects can be achieved at the same time.

[0006] As a preferred embodiment of the present invention, the actuator and / or the limiting part has a certain deformation capability, and the actuator is further provided with a mating boss, which directly contacts the limiting part to achieve core ejection limiting.

[0007] As a preferred embodiment of the present invention: the writing sleeve is provided with an anti-dislodgement component, which includes an anti-dislodgement part and a stop-dislodgement part. When the anti-dislodgement part is provided on the upper sleeve, the stop-dislodgement part is provided on the lower sleeve, and vice versa. The anti-dislodgement component can be expressed in many forms, but its main purpose is to ensure that the lower sleeve and the upper sleeve can extend and retract axially while preventing the lower sleeve and the upper sleeve from completely disengaging, so as to maintain the stability of the core-retracting state. Based on this, the anti-dislodgement component can be designed as a detachable or non-detachable assembly depending on the situation.

[0008] As a preferred embodiment of the present invention, the release element may take at least the following forms: 1. The slip ring assembly can be a single ring or a double ring; if it is a single ring, it is the actuating ring; if it is a double ring, it is both the actuating ring and the self-locking ring. 2. Rotating mating parts; 3. Extended pressing component; 4. The pressing boss is located on the actuator. When there is no other limiting structure between the upper sleeve rod and the lower sleeve rod, the pressing boss can form a limiting function with the limiting part to prevent the upper sleeve rod and the lower sleeve rod from separating when the core is retracted.

[0009] As a preferred embodiment of the present invention: the slip ring assembly 3 is a double ring, and the execution ring and the self-locking ring are connected by a threaded connection. The slip ring assembly 3 is sleeved on the writing sleeve rod. The execution ring can move axially relative to the upper sleeve rod 2 but cannot rotate. The self-locking ring can rotate relative to the upper sleeve rod 2, or can move axially or not move axially. The double ring can realize push-pull core retraction while adding a self-locking function. If the self-locking ring can move axially relative to the writing sleeve rod, the core can be retracted by pushing the slip ring assembly downward or by lifting the core without self-locking.

[0010] As a preferred embodiment of the present invention: under normal circumstances, the slip ring assembly can directly mate with the actuator or the mating boss, and when the actuator does not mate with the slip ring assembly, the actuator is further provided with a slip ring pusher that mates with the slip ring assembly.

[0011] As a preferred embodiment of the present invention: in order to ensure the best performance of the slip ring assembly and that its function is not affected by gravity, a return spring is also provided between the slip ring assembly and the writing rod.

[0012] As a preferred embodiment of the present invention, the execution unit (11) is further provided with a rotation control unit (61).

[0013] As a preferred embodiment of the present invention: in order to better realize the function of rotating core taking, the rotating fitting component is provided with one or more rotating adjustment parts that match the rotating control part. When the rotating fitting ring is rotated, the actuator will be displaced through the rotating adjustment part and the rotating control part. When multiple rotating adjustment parts are provided at the same time, the rotation can be unrestricted. No matter which position it is rotated to, there is a rotating adjustment part that can cooperate with the rotating control part.

[0014] As a preferred embodiment of the present invention: in order to better realize the function of pressing and retracting the core and enhance the actual experience of pressing and retracting the core, the extended pressing member is specifically provided on the lower sleeve rod, the slip ring sleeve group, the rotating fitting member or the upper sleeve rod.

[0015] As a preferred embodiment of the present invention: in order to better design the overall structure according to appearance requirements and meet the needs of different consumer groups, the actuator is further provided with a pressing transmission part that cooperates with the extended pressing part.

[0016] As a preferred embodiment of the present invention: in order to avoid the position of the thumb and forefinger gripping the pen refill when pulling it out, and to prevent the refill from being unable to be properly ejected after accidentally touching the extension pressing member, the extension pressing member or the pressing protrusion is located at a distance from the pen refill. Write at 3-35mm or 45-180mm from the end.

[0017] As a preferred embodiment of the present invention, the execution part and the limiting part are connected by a detachable limiting structure. When needed, they cooperate to limit the length of the writing sleeve, and when not needed, the limiting is released to restore the length of the writing sleeve.

[0018] As a preferred embodiment of the present invention: the core ejection is an axial lifting core ejection, the distance between the lowest end of the upper sleeve rod that can be directly contacted and the writing end of the pen refill is 3-80mm, and the lower sleeve rod can be directly contacted. By clamping one end with the web of one hand through the directly contactable parts of the lower sleeve rod and the upper sleeve rod, and then moving the other end with the fingers, the upper sleeve rod and the lower sleeve rod are moved closer together, thereby causing the actuator to move upward to the limiting part.

[0019] As a preferred embodiment of the present invention, a core replacement component can also be detached from the upper or lower sleeve rod.

[0020] As a preferred embodiment of the present invention: the limiting part is further provided with a core-collecting groove. Under normal circumstances, the core-collecting groove is located on the upper or lower side of the limiting part; when collecting the core, the actuating part is located in the core-collecting groove; when a core-collecting groove and a core-exiting guide slope are provided, the core-collecting groove can be enlarged, the area with the core-exiting guide slope above is the core-exiting area X, and the area without the core-exiting guide slope above forms the self-locking area Z, so that the actuating part can enter the self-locking area Z by rotation, thereby realizing self-locking.

[0021] As a preferred embodiment of the present invention, the actuator and / or the limiting part has a certain deformation capability, the actuator is further provided with a mating groove, and the limiting part is further provided with a limiting boss.

[0022] As a preferred embodiment of the present invention: the upper sleeve rod and / or the lower sleeve rod are further provided with a core-exiting guide slope. When the core is retracted, when the mating boss is located in the gap between the upper sleeve rod and the lower sleeve rod, and the core-exiting guide slope is not provided on the actuating part, the width of the core-exiting guide slope is limited so that the upper or lower side of the core-exiting guide slope forms a core-exiting area X, while the areas on both sides or one side of the core-exiting guide slope are self-locking areas Z, so that the mating boss enters the self-locking area Z by rotation, thereby achieving self-locking.

[0023] As a preferred embodiment of the present invention: the tail of the upper sleeve is provided with a core-exiting and core-receiving self-locking component. When the tail of the upper sleeve is provided with a core-changing component, the core-exiting and core-receiving self-locking component is located on the core-changing component. By rotating or pulling, the engagement distance between the core-exiting and core-receiving self-locking component and the upper sleeve or core-changing component is changed, thereby making the internal space of the writing sleeve longer or shorter. When the core-exiting and core-receiving self-locking component causes the internal space of the writing sleeve to become shorter, the core can be normally extruded and retracted through the positioning component. When the core-exiting and core-receiving self-locking component causes the internal space of the writing sleeve to become longer, the core cannot be extruded normally, and it is in a self-locking state. This method achieves self-locking by changing the length of the internal space of the writing sleeve.

[0024] As a further preferred embodiment of the present invention: the writing sleeve is provided with an anti-dislodgement component, which includes an anti-dislodgement part and a stop-dislodgement part. When the anti-dislodgement part is provided on the upper sleeve, the stop-dislodgement part is provided on the lower sleeve, and vice versa. The anti-dislodgement component can be expressed in many forms, but its main purpose is to ensure that the lower sleeve and the upper sleeve can extend and retract axially while preventing them from completely disengaging, thus maintaining the stability of the core-retracting state. Based on this, the anti-dislodgement component can be designed as a detachable or non-detachable assembly depending on the situation. In the absence of a self-locking function, the anti-dislodgement component can also restrict the rotation of the upper sleeve relative to the lower sleeve through its structure, so that the two can only move axially. When a self-locking function that requires the upper and lower sleeves to rotate is provided, the upper and lower sleeves can rotate slightly in addition to axial movement to meet the rotation requirements of the self-locking function.

[0025] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator and the limiting part only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively.

[0026] Compared with existing technologies, the above technical solution has the following beneficial effects: First, the operation methods are diverse and innovative, including various usage methods that can be accepted by most groups, providing more choices. These include pressing to retract the core, rotating to retract the core, pushing down to retract the core, pulling back to retract the core, and rotating with automatic pushing down for self-locking core retraction.

[0027] Second, the structure is simplified and the cost is reduced. While taking into account various operating methods, the structure is simplified and the number of parts is reduced through structural design, thereby reducing costs.

[0028] Third, it facilitates production and assembly, increases production output, and reduces the need for assembly labor. The structural design fully considers the actual production and assembly of the product, and most parts can be assembled by assembly line machinery, reducing the need for manual labor.

[0029] Fourth, the actual operation experience is excellent. The core is easily pulled out, while also providing a convenient core collection experience.

[0030] Fifth, the overall space utilization rate is extremely high, and the space ratio of the pen refill is extremely high, which greatly shortens the overall length and makes it very portable. It solves the problem of pocket pens on the market, and achieves the best of both worlds by adjusting the length and balancing portability with the capacity of the pen refill.

[0031] VI. To address the need for portability, through logical and detailed adjustments, the original structure is improved without adding any extra structures, thereby increasing the self-locking function. This greatly enhances the practicality of portability and reduces actual production costs, while ensuring the original appearance design. Attached Figure Description

[0061] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0062] like Figures 1 to 4 The illustrated pull-out pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the lower sleeve 1, and the limiting part 21 is located on the upper sleeve 2. When the lead is ejected, the actuator 11 moves up to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0063] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0064] To facilitate the pressing and retracting of the core, the upper sleeve rod 2 is also equipped with a release element, namely an extended pressing element A. When the extended pressing element A is pressed down, it will drive the actuator 11, affecting the downward displacement of the actuator 11.

[0065] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0066] To facilitate refill replacement, the actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to shorten the length of the writing sleeve. When not needed, the limiting is released to restore the length of the writing sleeve.

[0067] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the lower sleeve 1; the matching groove is provided on the upper sleeve 2. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0068] For ease of installation, the mating slot is unidirectionally through, allowing the anti-detachment part 12 to move more easily within the mating slot. The mating slot is provided with an anti-detachment part 22, which restricts the movement distance of the anti-detachment part 12 within the mating slot and makes it difficult for the anti-detachment part 12 to easily detach from the anti-detachment part 22.

[0069] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0070] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator 11 and the limiting part 21 only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively. Example 2

[0071] like Figures 5 to 7 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the upper sleeve 1, and the limiting part 21 is located on the lower sleeve 2. When the lead is ejected, the actuator 11 moves down to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0072] The writing sleeve is also equipped with two release components: a slip ring assembly 3 and an extension pressing component A. The writing sleeve is also equipped with a slip ring assembly 3.

[0073] The lower sleeve rod 1 is also provided with a core-out guide slope 212.

[0074] The slip ring assembly 3 is a double ring, specifically divided into an execution ring 33 and a self-locking ring 32. The execution ring 33 and the self-locking ring 32 are connected by a thread. The slip ring assembly 3 is sleeved on the writing sleeve rod. The execution ring 33 can move axially relative to the upper sleeve rod 2 but cannot rotate. The self-locking ring 32 can rotate relative to the upper sleeve rod 2 and can also move axially. The double ring can realize push-pull core retraction while adding a self-locking function. The extended pressing element A is provided on the actuating ring 33, which not only adds the function of pressing and retracting the core, but also facilitates operation.

[0075] When the actuator 11 does not cooperate with the slip ring assembly 3, the actuator 11 is also provided with a slip ring pusher 31 that cooperates with the slip ring assembly 3.

[0076] A return spring B is also provided between the execution ring 33 and the writing sleeve.

[0077] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0078] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0079] The actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to limit the length of the writing sleeve. When not needed, the limiting is released and the length of the writing sleeve is restored.

[0080] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the upper sleeve 2; the matching groove is provided on the lower sleeve 1. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0081] For ease of installation, the mating slot is unidirectionally through, allowing the anti-detachment part 12 to move more easily within the mating slot. The mating slot is provided with an anti-detachment part 22, which restricts the movement distance of the anti-detachment part 12 within the mating slot and makes it difficult for the anti-detachment part 12 to easily detach from the anti-detachment part 22.

[0082] The core extraction method is the same as in Example 1, which is to pull out the core.

[0083] The core-closing methods are: 1. Self-locking core-closing, 2. Push-pull core-closing, 3. Lifting core-closing, 4. Pressing core-closing. Example 3

[0084] like Figures 8-9 and Figure 16 The lifting pen shown is based on embodiment 3, with the addition of a new release component, namely the rotating mating component 6; The execution unit 11 is also provided with a rotation control unit 61. The writing sleeve is also provided with a rotation mating part 6 that controls the rotation of the execution unit 11 through the rotation control unit 61.

[0085] The rotating fitting 6 has one or more rotating adjustment parts 62 that match the rotating control part 61. When the rotating fitting ring 6 rotates, the actuator 11 will be displaced through the rotating adjustment part 62 and the rotating control part 61.

[0086] The core-gathering method described in Example 3 adds a rotating core-gathering feature! Example 4

[0087] like Figure 10 and Figure 11 The writing sleeve includes a retractable writing sleeve, a pen refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the upper sleeve 2, and the limiting part 21 is located on the lower sleeve 1. When the lead is ejected, the actuator 11 moves down to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0088] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0089] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0090] The lower sleeve rod 1 is also provided with a core-out guide slope 212.

[0091] To facilitate refill replacement, the actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to shorten the length of the writing sleeve; when not needed, the limiting is released to restore the length of the writing sleeve.

[0092] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the upper sleeve 2; the matching groove is provided on the lower sleeve 1. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0093] For ease of installation, the mating slot is unidirectionally through, allowing the anti-detachment part 12 to move more easily within the mating slot. The mating slot is provided with an anti-detachment part 22, which restricts the movement distance of the anti-detachment part 12 within the mating slot and makes it difficult for the anti-detachment part 12 to easily detach from the anti-detachment part 22.

[0094] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0095] A new release component, namely the rotating fitting component 6, has been added to the writing sleeve. The execution unit 11 is also provided with a rotation control unit 61. The writing sleeve is also provided with a rotation mating part 6 that controls the rotation of the execution unit 11 through the rotation control unit 61.

[0096] The rotating fitting 6 has one or more rotating adjustment parts 62 that match the rotating control part 61. When the rotating fitting ring 6 rotates, the actuator 11 will be displaced through the rotating adjustment part 62 and the rotating control part 61.

[0097] The core-gathering method is rotary core-gathering. Example 5

[0098] like Figures 12 to 13 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the upper sleeve 1, and the limiting part 21 is located on the lower sleeve 2. When the lead is ejected, the actuator 11 moves down to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0099] The writing sleeve is also equipped with a slip ring assembly 3.

[0100] The slip ring assembly 3 is a single ring, specifically divided into an execution ring 33. The execution ring 33 is sleeved on the writing sleeve rod. The execution ring 33 can move axially relative to the upper sleeve rod 2, but cannot rotate. It can also be equipped with an extension pressing component A to add the function of pressing and retracting the core.

[0101] When the actuator 11 does not cooperate with the slip ring assembly 3, the actuator 11 is also provided with a slip ring pusher 31 that cooperates with the slip ring assembly 3.

[0102] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0103] The lower sleeve rod 1 is also provided with a core-out guide slope 212.

[0104] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0105] The actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to limit the length of the writing sleeve. When not needed, the limiting is released and the length of the writing sleeve is restored.

[0106] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the upper sleeve 2; the matching groove is provided on the lower sleeve 1. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0107] For ease of installation, the mating slot is unidirectionally through, allowing the anti-detachment part 12 to move more easily within the mating slot. The mating slot is provided with an anti-detachment part 22, which restricts the movement distance of the anti-detachment part 12 within the mating slot and makes it difficult for the anti-detachment part 12 to easily detach from the anti-detachment part 22.

[0108] The core extraction method is the same as in Example 1, which is to pull out the core.

[0109] The core-gathering methods are: 1. Push-pull core gathering, 2. Lifting core gathering, 3. Pressing core gathering. Example 6

[0110] like Figures 14 to 15 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the lower sleeve 1, and the limiting part 21 is located on the upper sleeve 2. When the lead is ejected, the actuator 11 moves up to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0111] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0112] The upper side of the mating boss 111 is also provided with a core-exit guide slope 212.

[0113] To facilitate the pressing and retracting of the core, the upper sleeve rod 2 is also provided with an extended pressing member A. When the extended pressing member A is pressed down, it will drive the actuator 11 and affect the downward displacement of the actuator 11.

[0114] To facilitate refill replacement, the actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to shorten the length of the writing sleeve; when not needed, the limiting is released to restore the length of the writing sleeve.

[0115] In order to control the maximum distance of the writing sleeve extension and retraction, the limiting part 21 is also provided with a core-collecting groove 211; the mating boss 111 can move within the core-collecting groove 211 by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0116] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0117] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator 11 and the limiting part 21 only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively. Example 7

[0118] like Figures 17 to 19 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the lower sleeve 1, and the limiting part 21 is located on the upper sleeve 2. When the lead is ejected, the actuator 11 moves up to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0119] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating boss 111.

[0120] To facilitate the pressing and closing of the core, the upper sleeve 2 is also provided with an extended pressing member A. When the extended pressing member A is pressed down, it will drive the actuator 11 and affect the downward displacement of the actuator 11; the extended pressing member A is located near the front end of the writing sleeve, which facilitates the front end operation to press and close the core.

[0121] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0122] To facilitate refill replacement, the actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to shorten the length of the writing sleeve. When not needed, the limiting is released to restore the length of the writing sleeve.

[0123] The upper sleeve rod 2 can also be disassembled to obtain a core replacement component C.

[0124] To achieve self-locking, the upper sleeve rod 2 is also provided with a core-exiting guide slope 212. When the core is retracted, when the mating boss 111 is located in the gap between the upper sleeve rod 2 and the lower sleeve rod 1, the width of the core-exiting guide slope 212 is limited, so that the upper or lower side of the core-exiting guide slope 212 forms a core-exiting area X, while the areas on both sides or one side of the core-exiting guide slope 212 are self-locking areas Z. This allows the mating boss 111 to enter the self-locking area Z by rotation, thereby achieving self-locking. In addition to axial movement, the upper sleeve rod and the lower sleeve rod can also rotate slightly to meet the rotation requirements of the self-locking function.

[0125] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the lower sleeve 1; the matching groove is provided on the upper sleeve 2. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0126] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0127] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator 11 and the limiting part 21 only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively. Example 8

[0128] like Figures 20 to 21 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the lower sleeve 1, and the limiting part 21 is located on the upper sleeve 2. When the lead is ejected, the actuator 11 moves up to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0129] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating groove 113, and the limiting part 21 is also provided with a limiting boss 214.

[0130] To facilitate the pressing and retracting of the core, the upper sleeve 2 is also equipped with a release element, namely an extended pressing element A. When the extended pressing element A is pressed down, it will drive the actuator 11 and affect the downward displacement of the actuator 11; the extended pressing element A is located near the front end of the writing sleeve, which facilitates the front end operation to press and retract the core.

[0131] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0132] To facilitate refill replacement, the actuator 11 and the limiting part 21 are connected by a detachable limiting structure. When needed, they work together to shorten the length of the writing sleeve. When not needed, the limiting is released to restore the length of the writing sleeve.

[0133] The upper sleeve rod 2 can also be disassembled to obtain a core replacement component C.

[0134] The actuator 11 is also provided with a core-exit guide slope 212.

[0135] In order to control the maximum distance of the writing sleeve extension and retraction, the writing sleeve is provided with a non-disengaging part 12 and a matching groove. The non-disengaging part 12 is provided on the lower sleeve 1; the matching groove is provided on the upper sleeve 2. The non-disengaging part 12 can move within the matching groove by the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1.

[0136] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0137] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator 11 and the limiting part 21 only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively. Example 9

[0138] like Figures 22 to 23The lifting pen shown is based on embodiment 8, with the addition of a lead-out and lead-in self-locking component 7 on the lead-changing component C. The lead-out and lead-in self-locking component 7 replaces the function of the top pen lead in the lead-changing component C of embodiment 8. The engagement distance between the self-locking part 7 and the upper sleeve 2 or the replacement part C can be changed by rotating or pulling, thereby lengthening or shortening the internal space of the writing sleeve. When the self-locking part 7 causes the internal space of the writing sleeve to shorten, the core can be normally dispensed through the positioning component. However, when the self-locking part 7 causes the internal space of the writing sleeve to lengthen, the core cannot be dispensed normally, and it is in a self-locking state. This method achieves self-locking by changing the length of the internal space of the writing sleeve. Example 10

[0139] like Figures 24 to 26 The lifting pen shown is based on embodiment 6, but with an enlarged core-receiving groove 11. The area with a core-exit guide slope 212 above it is the core-exit area X, while the area without the core-exit guide slope 212 above it forms a self-locking area Z, so that the actuator 11 can enter the self-locking area Z by rotation, thereby achieving self-locking. Example 11

[0140] like Figures 27 to 29 The illustrated pen includes a retractable writing sleeve, a refill 5, and a refill spring 4. The writing sleeve includes a lower sleeve 1 and an upper sleeve 2 that are interlocked with each other; The pen refill 5 is located inside the writing sleeve; the retracting spring 4 is located between the pen refill 5 and the writing sleeve. By extending and retracting the writing sleeve, the pen refill 5 can have two position changes within the writing sleeve: retracted and extended. The writing sleeve is provided with a positioning component, which includes an execution part 11 and a limiting part 21; the execution part 11 is located on the lower sleeve 1, and the limiting part 21 is located on the upper sleeve 2. When the lead is ejected, the actuator 11 moves up to the limiting part 21. The limiting part 21 restricts the writing end of the lead 5 to remain exposed on the writing sleeve. When the refill is retracted, the actuator 11 and the limiter 21 separate, and the writing end of the pen refill 5 is completely retracted into the writing sleeve.

[0141] The actuator 11 has a certain deformation capability, and the actuator 11 is also provided with a mating groove 113, and the limiting part 21 is also provided with a limiting boss 214.

[0142] To facilitate the pressing and retracting of the core, the actuator 11 is also equipped with a release element, namely an actuator pressing boss D. When the actuator pressing boss D is pressed down, it will affect the downward displacement of the actuator 11; the actuator pressing boss D is located near the front end of the writing sleeve, which facilitates the front end operation to press and retract the core.

[0143] The writing sleeve is in a reset and telescopic state. The upper sleeve 2 and the lower sleeve 1 are connected by the pen refill 5. The retracting spring 4 is located between the pen refill outlet of the writing sleeve and the writing end of the pen refill 5.

[0144] The upper sleeve rod 2 can also be disassembled to obtain a core replacement component C.

[0145] The actuator 11 is also provided with a core-exit guide slope 212.

[0146] In order to control the maximum distance of the writing sleeve extension and retraction, the pressing boss D will create a limit between itself and the limiting part 21. After the pressing boss D and the limiting part 21 come into contact, the maximum distance of mutual extension and retraction of the upper sleeve 2 and the lower sleeve 1 is reached.

[0147] To ensure that the limiting boss 214 does not continuously press against the actuator 11 during core take-up, the actuator is also provided with a corresponding limiting slot 116 to accommodate the limiting boss 214 during core take-up.

[0148] The core ejection is achieved by lifting the core out. While keeping the upper sleeve rod 2 stationary, the lower sleeve rod 1 is moved towards the upper sleeve rod 2, and the boss 111 is engaged with the limiting part 21.

[0149] When the end of the pen refill rests against the upper sleeve, which also includes the pen grip area, the writing force acts on the upper sleeve during writing. The limiting force between the actuator 11 and the limiting part 21 only needs to be slightly greater than the spring force of the refill spring. At this time, the refill can be refilled by pulling the upper and lower sleeves with both hands respectively.

[0150] Additional notes on the invention: 1. There is a certain space gap between the actuator 11 and the pen refill, so that there is enough space when the actuator 11 or the cooperating boss 111 needs to move towards the pen refill.
