Description

Technical Field

[0001] This invention relates to a pen, and more particularly to a mechanical pen and its operating method. Background Technology

[0002] With the rapid development of the times, pens with trigger-activated retraction have begun to appear on the market. However, some trigger-activated pens have relatively complex structures or only have the function of trigger-activated retraction, and cannot simultaneously achieve both lift-up retraction and trigger-activated retraction. For example, CN202011512192.6 describes a 360-degree trigger structure and a pen using this structure. This technology enables the pen to trigger and retract 360 degrees, achieving excellent near-automatic retraction. This retraction method is highly effective and better reflects the rapid changes of the new era and the huge upgrade in pen operation, greatly improving people's pen operation experience and achieving better intelligence through mechanical technology. However, the spherical bearing used in this solution, although it is currently the most stable and common structure for 360-degree rotation mechanisms, is too expensive and difficult to produce for a 360-degree trigger-activated retraction pen.

[0003] Although the comparison document can achieve multiple core-gathering methods, this innovative structural design, while very effective, requires a relatively large force to trigger core-gathering, making it impossible to achieve true micro-trigger core-gathering while ensuring stable use.

[0004] Therefore, we need to produce the product in a way that is more conducive to production; and simultaneously combine both lifting and triggering core winding methods, while also having a high fault tolerance rate, a relatively stable product structure, and being easy to promote and mass-produce, while also being practical and providing a better user experience. This requires in-depth research and development and deep thinking to cleverly solve this problem. Through human-made structural design, we can reuse as many reusable structures and channels as possible, and solve the problem through some ingenious designs.

[0005] Therefore, the coordination and utilization rate of the structure need to be very good. The reusable parts should be upgraded to achieve better results. This sounds simple, but in reality, it takes a lot of effort to overcome the technical difficulties and limitations in thinking. At the same time, it requires the spirit of craftsmanship to strive for excellence in order to make a huge breakthrough on the premise that the existing structure is already very good, so as to achieve the function of lifting and core gathering at the same time. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of poor trigger sensitivity and insufficient stability of existing pen triggering technology, the difficulty in achieving both sensitivity and stability, the excessively high quality requirements, the difficulty in achieving a high yield rate during mass production, the inability to combine trigger-triggered retraction and lifting-triggered retraction, and the complex structure. The invention provides a mechanical pen and its operation method.

[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0008] A mechanical pen and its operating method are disclosed. An adjusting member configured within an outer rod moves along a positioning groove, thereby determining the position of the tool body. The positioning groove has two stopping points: a lead-out point and a lead-retracting point. The tool body can then be in either a lead-retracting or lead-out position depending on the stopping position of the displacement member. The adjusting member achieves relative stability between these two positional states through the positioning member or the positioning groove, reset member, and control member on the outer rod. The reset member, driven by the tool body, continuously provides a force to the adjusting member, ensuring relative stability of the displacement member's position at the lead-retracting and lead-out points. When the displacement member moves to the lead-out point in the positioning groove, the control member restricts the displacement member, further stabilizing the lead-out position.

[0009] By controlling the movement of the adjusting component, the displacement component can be made to cross or bypass the restriction of the control component by switching the long wall, or the restriction of the control component on the displacement component can be released by moving the control component, and the component can return to the core-gathering point, thereby achieving core gathering.

[0010] By controlling the movement of the adjusting component, the displacement component is moved from the core receiving point to the core exiting point, thus achieving core exiting.

[0050] As a further preferred embodiment of the present invention: the switching from the core output state to the core recovery state can be achieved by selecting at least one of the following four methods:

[0051] VII. Push-rod core-collecting scheme one: External force presses the push-rod (75) to one end of the contact displacement member (41), causing the push-rod (75) to press the displacement member (41) to disengage from the core-exiting table (73); when the displacement member (41) disengages from the core-exiting table (73), it is subjected to the action of the reset member (3), and the displacement member (41) moves down to the core-collecting point (A);

[0052] 8. Push rod core-collecting scheme two: The external force lifts one end of the push rod (75) away from the displacement member (41), so that the other end of the push rod (75) is affected by the linkage and squeezes the displacement member (41) to disengage from the core-exiting table (73); when the displacement member (41) disengages from the core-exiting table (73), it is subjected to the action of the reset member (3), and the displacement member (41) moves down to the core-collecting point (A);

[0053] 10. Lifting and core-gathering scheme three: The external force controls the adjustment component (4) to move upward. By not using the switching ramp (76), the displacement component (41) deforms backward. When the deformation reaches a certain degree, the external force is released and affected by the reset component (3). The displacement component (41) will pass through the core-out table (73), but will not cooperate with the core-out table (73). Instead, it will fall directly into the core-gathering point (A).

[0054] XI. Reverse push core collection scheme: Keep the outer rod (1) still, and use external force to pull the adjustment component (4) down or up. By pushing the auxiliary slope (417), the displacement component (41) is freed from the restriction of the core exiting platform (73) and returns to the core collection point (A).

[0055] 12. Pressing and collecting core scheme three: Press the trigger ring (62) with external force, so that the trigger ring (62) squeezes the trigger cover (63) or the trigger element (64), so that the trigger cover (63) or the trigger element (64) squeezes the control element (2), and the control element (2) causes the displacement element (41) to move inward, so that the displacement element (41) and the core outlet table (73) are disengaged, and the displacement element (41) returns to the core collection point (A) through the reset element (3);

[0056] 9. Triggering Core Retrieval Scheme 2: Through the transmission of the trigger component (6), the control component (2) moves, causing the displacement component (41) to break free from the restriction of the core ejection table (73). Then the displacement component (41) will be affected by the reset component (3) and move, thereby realizing core retrieval.

[0057] As a further preferred embodiment of the present invention: the switching from the core-receiving state to the core-discharging state can be achieved by the following method:

[0058] VII. Core Extraction Scheme 4: External force controls the adjustment component (4) to move upward, and the displacement component (41) moves directly from the core receiving point (A) to the core extraction platform (73) and engages with the core extraction platform (73), thus completing the core extraction;

[0059] VIII. Core Extraction Scheme 5: External force controls the adjustment component (4) to move upward, and the displacement component (41) moves upward from the core receiving point (A), and reaches the core extraction platform (73) through the extension switching slope (415) and / or the blocking entry slope (171), and forms a lock with the core extraction platform (73), then the core extraction is completed;

[0060] The aforementioned movement control core retraction and lifting core retraction can be achieved simultaneously; the aforementioned movement control core retraction method can be upgraded to trigger core retraction by adding a trigger component. The trigger core retraction is achieved when the trigger component receives a 360-degree external force transmission to the control component, causing the control component to undergo a corresponding displacement.

[0061] When trigger-based core take-up is used, the trigger-based core take-up and pull-up core take-up mentioned above can be achieved simultaneously.

[0062] When the adjusting component is in the upper half of the outer rod, the above-mentioned core-pulling operation changes to core-pressing operation when the core is pulled out by the adjusting component above the top of the outer rod. The original core-pulling operation also changes to core-pressing operation. The operation method is: keep the outer rod still, and use external force to control the adjusting component to move down to achieve core-pressing operation or core-pressing operation.

[0063] When pressing to deliver the core and pressing to retract the core are used, the adjusting component is also provided with a pressing component, which can facilitate better control of the adjusting component;

[0064] When pressing to extend and pressing to retract the core are used, the aforementioned movement control for core retraction becomes another form of pressing-down core retraction. However, the trigger stroke of this pressing-down core retraction is much shorter than that of the original pressing-down core retraction. Therefore, pressing-down core retraction is much more sensitive than pressing-down core retraction. By upgrading the triggering component, pressing-down core retraction can also be upgraded to trigger-based core retraction.

[0065] When using the press-to-extract mechanism, pressing to expel the core and pressing down to retract the core can be performed simultaneously; when pressing down to retract the core is upgraded to triggering to retract the core, pressing to expel the core and triggering to retract the core can be performed simultaneously.

[0066] The simultaneous implementation of the above means that a product has both of these different operating methods, thereby bringing a more comprehensive and high-quality experience.

[0067] The core-receiving state is switched to the core-exiting state by lifting the core out: keeping the outer rod stationary, external force controls the adjusting component to move the displacement component upward, thereby re-entering the constraint of the control component and the positioning groove.

[0068] Compared with existing technologies, the above technical solution has the following beneficial effects:

[0069] I. Comprehensive optimizations and improvements have been made to the stability of the pen in the lead-out state, the stability of the lead-retracting state, the stability and smoothness of switching from lead-out to lead-retracting state, the overall appearance and stability, the compression and optimization of the overall internal space, and the adjustment of the trigger force conversion ratio.

[0070] Second, by optimizing the structure, the effect of removing foreign objects and resetting is achieved, reducing the minimum force required for triggering and greatly improving the triggering effect, which greatly enhances the actual user experience and better realizes the triggering and core retraction.

[0071] Third, through structural integration and optimization of external components, better results can be achieved in reducing costs and assembly difficulty.

[0072] Fourth, by improving the reusability of the structure, and simultaneously achieving both pull-up and trigger-based core take-up, both core take-up methods have great market value and a very good user experience, and also meet the needs of different customers.

[0073] Fifth, it can transmit more external triggering force, thus achieving better triggering and core retraction.

[0074] VI. It greatly reduces costs and assembly difficulty.

[0075] 10. The trigger ring has been modified with a trigger ramp to further improve the triggering effect;

[0076] 12. Strict control was exercised over all details of the core-pulling and winding process, reducing the precision requirements and thus greatly improving the fault tolerance rate, which is more conducive to production and assembly.

[0077] Thirteen, improve product utilization and adaptability to various scenarios, save consumers' money and reduce the burden on the environment.

[0078] 15. Through optimization of the joint bearing, although the joint bearing is a mature and very stable technology, after multiple tests, it was found that for the actual 360-degree triggering of the pen, the stability of the joint bearing brings high cost to the pen and kills some possibilities.

[0079] On the contrary, the instability of the 360-degree triggering structure adopted in this invention can actually achieve better technical results. It not only greatly reduces production costs and assembly difficulty, but also represents a new breakthrough in the original technical effects achievable by spherical plain bearings.

[0080] This invention achieves a semi-circular triggering effect, adding a top 360-degree angled triggering angle and a top triggering core retraction to the existing 360-degree triggering angle. This breakthrough not only greatly expands the triggering range but also achieves a better triggering effect. The stability provided by the joint bearing inevitably absorbs triggering forces generated outside the triggering range, preventing the transmission of these forces. However, the scenarios in which pens are used are highly variable, meaning that triggering forces exceeding the joint bearing's triggering range are inevitable in most cases. The 360-degree triggering structure used in this invention, with its larger triggering range and semi-circular triggering core retraction, can transmit triggering forces across the entire semi-circular range. Therefore, the joint bearing consumes more external triggering force. The 360-degree triggering structure further reduces the external triggering force consumed by the structure itself, allowing for the transmission of more external triggering force when external triggering force is limited, thus better achieving triggering core retraction.

[0081] The advantages brought about by the new breakthrough include at least the following three points:

[0082] 1. A semi-circular core-gathering mechanism has been implemented, greatly increasing the triggering range to cover 360 degrees on the side, 360 degrees diagonally at the top, and 360 degrees at the top.

[0083] 2. It can transmit more external triggering force, thus achieving better triggering and core retraction;

[0084] 3. It greatly reduces costs and assembly difficulty.

[0085] Sixteen, the transmission method of the trigger component has been optimized to adopt a direct contact transmission method. With this method, the mating point between the automatic pen clip and the pen, whether using a hinge connection, a joint bearing, a 360-degree rotation connection or other connection methods, can be disassembled and hidden inside the pen for assembly, reducing assembly difficulty and cost, while improving the pen's appearance and stability in use.

[0086] 17. The center-pressing method achieves better downward movement of the pressing component. With the distance between the rotating rod and the pressing component remaining constant, the downward pressing distance of the pressing component can be significantly increased, greatly improving pressing efficiency. In contrast, the 360° tilting downward movement method used in Appendix 13 of the comparative document to switch from core ejection to core retraction involves extrusion from the inside out. This extrusion method is more laborious, and the rotation from the inside out with the joint bearing as the origin results in a gradual increase in the horizontal height of the contact point between the trigger and the internal trigger. The main purpose of tilting the trigger is to press down the internal trigger. The comparative document's method results in a mutual cancellation of downward movement distances, leading to a smaller final downward movement distance, thus making it inefficient. The tilting downward movement method, using an outside-in extrusion process, requires less effort. Furthermore, the horizontal height of the contact point between the trigger and the control component gradually decreases, resulting in a greater final downward movement distance. This trade-off, given that the initial downward movement distance of this method is relatively small, makes the increased downward movement distance quite significant, making core triggering and retraction easier.

[0099] The present invention will now be further described with reference to the accompanying drawings. Example

[0100] like Figures 1-3 The components shown include an outer rod 1, a reset component 3, a tool body 5, and an adjusting component 4;

[0101] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0102] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74; the aforementioned core ejector plate 73 and / or displacement member 41 are also provided with a reverse thrust ramp 417.

[0103] The aforementioned control component 2 is equipped with a release auxiliary ramp 24.

[0104] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0105] The tool body 5 and the reset member 3 are placed inside the adjusting member 4, with the reset member 3 specifically located between the tool body 5 and the adjusting member 4. The tail end of the tool body 5 abuts against the lower end of the positioning part 72.

[0106] The aforementioned inner moving groove 74 is the core receiving point A. The aforementioned core exiting platform 73 is the core exiting point B.

[0107] The aforementioned triggering component 6 is used to collect external triggering force and transmit it to the control component 2, thereby controlling the movement of the release auxiliary slope 24.

[0108] The aforementioned control component 2 and adjusting component 4 are slidably sleeved inside the outer rod 1:

[0109] The aforementioned displacement component 41 is located at the core-gathering point A. At this time, the tool body 5 remains completely hidden inside the adjustment component 4, which is the core-gathering state.

[0110] When the aforementioned displacement component 41 is located at the core exit point B, the writing part of the tool body 5 will expose the adjustment component 4, which is the core exit state.

[0111] The aforementioned trigger assembly 6 includes a trigger element 64, a trigger ring 62, and a rotating fastener 65. The trigger element 64 is connected to the trigger ring 62 via the rotating fastener 65. The rotating fastener 65 is fixed to the top of the outer rod 1. The trigger element 64 has a rotating ring protrusion 641 at its middle end and a trigger ring protrusion 642 at its lower end. The trigger element 64 can tilt and / or move downward relative to the rotating fastener 65 by 360 degrees via the rotating ring protrusion 641. The rotating ring protrusion 641 cannot pass through the rotating fastener 65. The top of the control element 2 has a downward moving ring protrusion 22. When the trigger ring protrusion 642 moves towards the center, it will squeeze the downward moving ring protrusion 22, indirectly causing the release auxiliary slope 24 to move downward. The downward movement of the release auxiliary slope 24 will cause the displacement element 41 to disengage from the core ejector 73, and thus fall back into the inner moving groove 74 under the influence of the reset element 3.

[0112] The trigger ring protrusion 642 directly abuts against the control member 2. When the trigger member 64 rotates and / or moves downward, it will cause the control member 2 to move downward. When the control member 2 moves downward, it will control the displacement member 41 to move inward by releasing the auxiliary slope 24, thereby causing the cooperation between the displacement member 41 and the core ejection stage 73 to disappear.

[0113] When the adjusting member 4 is inserted into the outer rod 1 and the displacement member 41 enters above the core-collecting boss 74, it is restricted by the inner moving groove 74 and is not easy to detach.

[0114] In this embodiment, the reset component 3 and the auxiliary reset component 31 use the repulsive force between magnets instead of the spring solution in other embodiments.

[0115] This embodiment can also achieve reverse push core recovery: keeping the outer rod 1 stationary, the external force pulls the adjustment component 4 down, and through the reverse push auxiliary slope 417, the above-mentioned displacement component 41 is freed from the restriction of the core exiting platform 73, thereby returning to the core recovery point A.

[0116] Installation method:

[0117] 1. First, install the auxiliary reset component, control component, trigger component, and rotating fastener into the outer rod in order from top to bottom, and mate the rotating fastener with the outer rod;

[0118] 2. Next, insert the adjusting component into the outer rod from bottom to top. The displacement component will enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0119] 3. Next, insert the main body of the tool, the reset part, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0120] 4. Finally, assemble the trigger ring and the trigger element together.

[0121] The core ejection method adopts the fourth lifting core ejection scheme: while keeping the outer rod 1 stationary, the adjusting component 4 is moved towards the trigger component end by external force. This causes the displacement component 41 to move from the inner moving groove 74 to the core ejection platform 73. Then, the external force is released, and the displacement component 41 will be engaged with the core ejection platform 73 by the force of the reset component 3, thereby maintaining the core ejection state.

[0122] It simultaneously supports the following three core-collecting methods:

[0123] 1. Pressing and collecting core scheme three: Press the trigger ring 62 with external force, so that the trigger ring 62 squeezes the trigger cover 63 or the trigger element 64, thereby causing the trigger cover 63 or the trigger element 64 to squeeze the control element 2. The control element 2 causes the displacement element 41 to move inward, thereby disengaging the displacement element 41 from the core outlet table 73. The reset element 3 causes the displacement element 41 to return to the core collection point A.

[0124] 2. Reverse push core collection scheme one: Keep the outer rod 1 stationary, pull the adjustment piece 4 downward with external force, and through the reverse push auxiliary slope 417, the above-mentioned displacement piece 41 is freed from the restriction of the core exiting platform 73, and thus returns to the core collection point A;

[0125] 3. Triggering the retraction scheme two: When the product of this invention is placed directly on a storage item such as a desktop, schoolbag, pencil case or pocket, the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the trigger ring 62, causing the trigger ring 62 to tilt, which will cause the control member 2 to move down. When the control member 2 moves down, the control member 2 will cause the displacement member 41 and the retraction plate 73 to disengage. Then the displacement member 41 will be acted upon by the reset member 3 and slide down to the retraction point A. At this time, the main body of the tool will be completely hidden in the pen changing part D. Example

[0126] like Figures 4-5 The above describes a mechanical pen and its operating method.

[0127] A mechanical pen and its operating method.

[0128] It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment component 4;

[0129] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0130] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0131] The aforementioned control component 2 is equipped with a release auxiliary ramp 24.

[0132] The maximum movement distance of the displacement member 41 is limited by the inner moving groove 74, thereby preventing the adjusting member 4 from detaching from the outer rod 1 after being inserted into the outer rod 1;

[0133] The aforementioned inner moving groove 74 does not penetrate the outer rod 1, is located on the inner wall of the outer rod 1, and is directly connected to the core ejector stage 73;

[0134] To trigger the retraction of the core, the outer rod 1 is provided with a connecting body 11 and a trigger assembly 6; the trigger assembly 6 includes a limiting member 61, a control member 2, a trigger ring 62, and a trigger cover 63; the lower end of the control member 2 is provided with a release auxiliary slope 24; the limiting member 61 passes through the trigger cover 63 and is connected to the connecting body 11, and the trigger cover 63 passes through the connecting body 11 and is connected to or abuts against the control member 2; when the trigger cover 63 moves downward, the control member 2 will also be pressed downward; the trigger ring 62 is located between the limiting member 61 and the trigger cover 63; a trigger auxiliary inclined ring C is provided on the lower side of the limiting member 61, the upper side of the trigger ring 62, the lower side of the trigger ring 62, and / or the upper side of the trigger cover 63.

[0135] An auxiliary reset component 31 is also provided between the positioning part 72 and the control component 2.

[0136] In order to achieve the core retraction of the pressing rod, the outer rod 1 is provided with a pressing rod 75; the core ejection platform 73 is provided with a linkage channel 731 that passes through the outer rod 1, and the displacement member 41 makes contact with the pressing rod 75 through the linkage channel 731; the pressing rod 75 is installed on the outer rod 1 by integral molding.

[0137] In order to enable the push rod to bring a wider position without hindering the contact and transmission between the push rod and the displacement component, the push rod 75 is provided with a pressing protrusion 751.

[0138] As an extension of its uses, the aforementioned lever 75 can also be used as a pen clip.

[0139] In order to better contact and cooperate with the push rod, the displacement component 41 is also provided with a displacement latch 411.

[0140] Installation method:

[0141] 1. First, install the auxiliary reset component, control component, trigger component, and rotating fastener into the outer rod in order from top to bottom, and mate the rotating fastener with the outer rod;

[0142] 2. Next, insert the adjusting component into the outer rod from bottom to top. The displacement component will enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0143] 3. Next, insert the main body of the tool, the reset part, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0144] The core ejection method adopts the fourth method of lifting core ejection: the external force controls the adjustment component 4 to move upward, and the above-mentioned displacement component 41 moves directly from the core receiving point A to the core ejection platform 73, and forms a lock with the core ejection platform 73, thus completing the core ejection;

[0145] It also features the following four core-collecting methods:

[0146] 1. Pressing and collecting core scheme three: Press the trigger ring 62 with external force, so that the trigger ring 62 squeezes the trigger cover 63 or the trigger element 64, thereby causing the trigger cover 63 or the trigger element 64 to squeeze the control element 2. The control element 2 causes the displacement element 41 to move inward, thereby disengaging the displacement element 41 from the core outlet table 73. The reset element 3 causes the displacement element 41 to return to the core collection point A.

[0147] 2. Reverse push core collection scheme one: Keep the outer rod 1 stationary, pull the adjustment piece 4 downward with external force, and through the reverse push auxiliary slope 417, the above-mentioned displacement piece 41 is freed from the restriction of the core exiting platform 73, and thus returns to the core collection point A;

[0148] 3. Triggering the retraction scheme two: When the product of this invention is placed directly on a storage item such as a desktop, schoolbag, pencil case, or pocket, the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the trigger ring 62, causing the trigger ring 62 to move downward, which in turn causes the trigger cover 63 to move downward. The downward movement of the trigger cover 63 causes the control component 2 to move downward. When the control component 2 moves downward, it causes the displacement component 41 and the retraction plate 73 to disengage. As a result, the displacement component 41 will be acted upon by the reset component 3 and slide down to the retraction point A. At this time, the main body of the tool will be completely hidden inside the pen changing part D.

[0149] 4. Push rod core-collecting scheme one: External force presses one end of the push rod 75 to contact the displacement member 41, causing the push rod 75 to press the displacement member 41 to disengage from the core-exiting table 73; when the displacement member 41 disengages from the core-exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core-collecting point A. Example

[0150] like Figure 6 The above describes a mechanical pen and its operating method.

[0151] A mechanical pen and its operating method.

[0152] It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment component 4;

[0153] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0154] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0159] In order to facilitate the installation of the displacement component 41 and provide sufficient space during deformation, the rear end of the displacement component 41 is also provided with a displacement notch 416.

[0160] As an extension of its uses, the aforementioned lever 75 can also be used as a pen clip.

[0161] In order to better contact and cooperate with the push rod, the displacement component 41 is also provided with a displacement latch 411.

[0162] Installation method:

[0163] 1. First, insert the adjusting component into the outer rod from bottom to top. The displacement component will then enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0164] 2. Next, insert the main body of the tool, the reset part, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0165] The core ejection method adopts the fourth method of lifting core ejection: the external force controls the adjustment component 4 to move upward, and the above-mentioned displacement component 41 moves directly from the core receiving point A to the core ejection platform 73, and forms a lock with the core ejection platform 73, thus completing the core ejection;

[0166] Core collection method: Core collection scheme 1 using the push rod: External force presses one end of the push rod 75 to contact the displacement member 41, causing the push rod 75 to press the displacement member 41 to disengage from the core exiting table 73; when the displacement member 41 disengages from the core exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core collection point A. Example

[0167] like Figures 7-8 The above describes a mechanical pen and its operating method.

[0168] A mechanical pen and its operating method.

[0169] It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment component 4;

[0170] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0171] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0172] The aforementioned adjusting member 4 limits the maximum movement distance of the displacement member 41 through the inner moving groove 74;

[0173] The aforementioned inner moving groove 74 does not penetrate the outer rod 1, is located on the inner wall of the outer rod 1, and is directly connected to the core ejector stage 73;

[0174] In order to achieve the core retraction of the pressing rod, the outer rod 1 is provided with a pressing rod 75; the core ejection platform 73 is provided with a linkage channel 731 that passes through the outer rod 1, and the displacement member 41 makes contact with the pressing rod 75 through the linkage channel 731; the pressing rod 75 is installed on the outer rod 1 as a separate accessory; the pressing rod 75 is installed in a fixed manner.

[0175] In order to enable the push rod to bring a wider position without hindering the contact and transmission between the push rod and the displacement component, the push rod 75 is provided with a pressing protrusion 751.

[0176] In order to facilitate the installation of the displacement component 41 and provide sufficient space during deformation, the rear end of the displacement component 41 is also provided with a displacement notch 416.

[0177] As an extension of its uses, the aforementioned lever 75 can also be used as a pen clip;

[0178] In order to better contact and cooperate with the push rod, the displacement component 41 is also provided with a displacement latch 411.

[0179] Installation method:

[0180] 1. First, insert the adjusting component into the outer rod from bottom to top. The displacement component will then enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0181] 2. Then, attach the push rod 75 to the end of the outer rod 1;

[0182] 3. Finally, insert the main body of the tool, the reset part, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0183] The core ejection method adopts the fourth method of lifting core ejection: the external force controls the adjustment component 4 to move upward, and the above-mentioned displacement component 41 moves directly from the core receiving point A to the core ejection platform 73, and forms a lock with the core ejection platform 73, thus completing the core ejection;

[0184] Core collection method: Core collection scheme 1 using the push rod: External force presses one end of the push rod 75 to contact the displacement member 41, causing the push rod 75 to press the displacement member 41 to disengage from the core exiting table 73; when the displacement member 41 disengages from the core exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core collection point A. Example

[0185] like Figures 9-10 The above describes a mechanical pen and its operating method.

[0186] It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment component 4;

[0187] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0188] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0189] The aforementioned adjusting member 4 is prevented from detaching from the outer rod 1 by means of the following:

[0190] The maximum movement distance of the displacement member 41 is limited by the inner moving groove 74;

[0191] The aforementioned inner moving groove 74 does not penetrate the outer rod 1, but is located on the inner wall of the outer rod 1 and is directly connected to the core ejector plate 73;

[0192] To achieve the lifting and core-gathering, the outer rod 1 is also provided with a cover 9, and the cover 9 is also provided with a non-use switching ramp 76. By not using the switching ramp 76, the lifting and core-gathering can be achieved. When core-gathering is required, the adjusting member 4 is moved further upward. By not using the switching ramp 76, the displacement member 41 is further deformed backward. When the deformation reaches a certain extent, it is released. The elastic force of the reset member 3 makes the speed at which the displacement member 41 falls back greater than the speed at which the displacement member 41 recovers its deformation. Therefore, when the displacement member 41 passes the core-exiting platform 73, it will not be locked back into the core-exiting platform 73, but will fall back to the bottom, which is the core-gathering limit point.

[0193] To achieve core retraction by the push rod, the outer rod 1 is provided with a push rod 75; the core ejector plate 73 is provided with a linkage channel 731 that passes through the outer rod 1, and the displacement member 41 makes contact with the push rod 75 through the linkage channel 731; the push rod 75 is a separate accessory, independent of the outer rod 1; the push rod 75 can be flexibly installed, so that the push rod 75 can rotate relative to the outer rod;

[0194] In order to enable the push rod to bring a wider position without hindering the contact and transmission between the push rod and the displacement component, the push rod 75 is provided with a pressing protrusion 751.

[0195] In order to facilitate the installation of the displacement component 41 and provide sufficient space during deformation, the rear end of the displacement component 41 is also provided with a displacement notch 416.

[0196] As an extension of its uses, the aforementioned push rod 75 can also be used as a pen clip, and can achieve pen clip retraction.

[0197] In order to better contact and cooperate with the push rod, the displacement component 41 is also provided with a displacement latch 411.

[0198] Installation method:

[0199] 1. First, insert the adjusting component into the outer rod from bottom to top. The displacement component will then enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0200] 2. Then install the cover 9 onto the outer rod;

[0201] 2. Then install the push rod 75 on the side of the outer rod 1;

[0202] 3. Finally, insert the main body of the tool, the reset piece, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0203] The core ejection method adopts the fourth lifting core ejection scheme: the external force controls the adjustment component 4 to move upward, and the above-mentioned displacement component 41 moves directly from the core receiving point A to the core ejection platform 73, and forms a lock with the core ejection platform 73, thus completing the core ejection;

[0204] Core winding method:

[0205] 1. Push rod core-collecting scheme one: External force presses one end of the push rod 75 to contact the displacement member 41, causing the push rod 75 to press the displacement member 41 to disengage from the core-exiting table 73; when the displacement member 41 disengages from the core-exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core-collecting point A.

[0206] 2. Push rod core collection scheme two: The external force lifts one end of the push rod 75 away from the displacement member 41, so that the other end of the push rod 75 is affected by the linkage and squeezes the displacement member 41 to disengage from the core exiting table 73; when the displacement member 41 disengages from the core exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core collection point A.

[0207] 3. Lifting and core-gathering scheme three: External force controls the adjustment component 4 to move upward. By not using the switching slope 76, the displacement component 41 is deformed backward. When the deformation reaches a certain extent, the external force is released and affected by the reset component 3. The displacement component 41 will pass through the core-out table 73, but will not cooperate with the core-out table 73. Instead, it will fall directly into the core-gathering point A. Example

[0208] like Figures 11-12 The above describes a mechanical pen and its operating method.

[0209] It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment component 4;

[0210] The outer rod 1 is provided with a core ejector plate 73, an inner moving groove 74 and a positioning part 72;

[0211] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves between the core ejector plate 73 and the inner moving groove 74.

[0212] The aforementioned adjusting member 4 is prevented from detaching from the outer rod 1 by means of the following: the outer rod 1 is also provided with a maximum limiting boss 77, and the aforementioned adjusting member 4 is also provided with a limiting ring platform 44, the maximum moving distance of the limiting ring platform 44 is limited by the maximum limiting boss 77.

[0213] The aforementioned inner moving groove 74 passes through the outer rod 1, and an exposed through hole 17 is provided on the lower side of the core ejector plate 73; in order to facilitate the movement of the displacement member 41 into the core ejector plate 73, the displacement member 41 is provided with an extension switching slope 415 and / or an obstruction entry slope 171 is provided below the exposed through hole 17.

[0214] To achieve core lifting and retraction, the outer rod 1 is also equipped with a non-use switching ramp 76. By not using the switching ramp 76, core lifting and retraction can be achieved. When core retraction is needed, the adjusting member 4 is moved further upward. By not using the switching ramp 76, the displacement member 41 is further deformed backward. When the deformation reaches a certain extent, it is released. The elastic force of the reset member 3 makes the speed at which the displacement member 41 falls back greater than the speed at which the displacement member 41 recovers its deformation. Therefore, when the displacement member 41 passes the core exiting platform 73, it will not be locked back into the core exiting platform 73, but will fall back to the bottom, which is the core retraction limit.

[0215] To achieve core retraction by the push rod, the outer rod 1 is provided with a push rod 75; the core ejector plate 73 is provided with a linkage channel 731 that passes through the outer rod 1, and the displacement member 41 makes contact with the push rod 75 through the linkage channel 731; the push rod 75 is a separate accessory, independent of the outer rod 1; the push rod 75 can be flexibly installed, so that the push rod 75 can rotate relative to the outer rod;

[0216] In order to enable the push rod to bring a wider position without hindering the contact and transmission between the push rod and the displacement component, the push rod 75 is provided with a pressing protrusion 751.

[0217] In order to facilitate the installation of the displacement component 41 and provide sufficient space during deformation, the rear end of the displacement component 41 is also provided with a displacement notch 416.

[0218] As an extension of its uses, the aforementioned push rod 75 can also be used as a pen clip, and can achieve pen clip retraction.

[0219] In order to better contact and cooperate with the push rod, the displacement component 41 is also provided with a displacement latch 411.

[0220] Installation method:

[0221] 1. First, insert the adjusting component into the outer rod from bottom to top. The displacement component will then enter the inner moving groove to form a lock. At this point, the adjusting component will not easily come off the outer rod.

[0222] 2. Then, attach the push rod 75 to the end of the outer rod 1;

[0223] 3. Finally, insert the main body of the tool, the reset part, and the pen changing part into the adjusting rod in sequence, and then assemble the pen changing part and the adjusting rod.

[0224] The core extraction method adopts the fifth method of lifting core extraction: the external force controls the adjustment component 4 to move upward, the above-mentioned displacement component 41 moves upward from the core receiving point A, and reaches the core extraction platform 73 through the extension switching slope 415 and / or the blocking entry slope 171, and forms a lock with the core extraction platform 73, thus completing the core extraction.

[0225] The following two methods are used simultaneously for core winding:

[0226] 1. Push rod core-collecting scheme one: External force presses one end of the push rod 75 to contact the displacement member 41, causing the push rod 75 to press the displacement member 41 to disengage from the core-exiting table 73; when the displacement member 41 disengages from the core-exiting table 73, it is subjected to the action of the reset member 3, and the displacement member 41 moves down to the core-collecting point A.

[0227] 3. Lifting and core-gathering scheme three: External force controls the adjustment component 4 to move upward. By not using the switching slope 76, the displacement component 41 is deformed backward. When the deformation reaches a certain extent, the external force is released and affected by the reset component 3. The displacement component 41 will pass through the core-out table 73, but will not cooperate with the core-out table 73. Instead, it will fall directly into the core-gathering point A.

[0228] Additional points that are present in all of the above embodiments 1-6:

[0229] 1. To facilitate pen refill replacement and installation, the front end of the aforementioned adjustment component or outer rod can be detached to form a pen replacement section D.

[0230] 2. The aforementioned tool body 5 is itself an internally contained tool, which is the foundation of writing. However, there are many writing media, and their external structural shapes can be relatively uniform. Therefore, the aforementioned tool body includes ballpoint pen refills, gel pen refills, fountain pen writing refills and ink cartridges, highlighter pen refills, rollerball pen refills, erasable pen refills, eyebrow pencils, screwdrivers, keys, craft knives, lipsticks, permanent pen refills and / or pencil refills.

[0231] 3. The essence of the above-mentioned reset element 3 is to provide a continuous force. Therefore, the above-mentioned reset element 3 and auxiliary reset element 31 are elastic materials, magnetic materials, elastic materials and / or reset springs, or are formed individually or in combination.

[0232] 4. The elastic force of the auxiliary reset component 31 is less than that of the reset component 3.

[0233] Special supplementary notes:

[0234] 1. In the embodiment: "The control lever 21 can only move up and down or forward and backward relative to the positioning groove 71, but cannot move left and right." This is based on the actual situation in the embodiment and is for the sake of stability when writing. It does not mean that this design is necessary. It is also possible to use diagonal upward, diagonal downward, diagonal forward, diagonal backward, left and right movement. However, the operation experience will be worse, and the internal structure needs to be designed with an additional guide structure that matches this operation orientation. Moreover, when the adjustment member is kept stationary, the positioning member needs to have the ability to rotate. In this case, the positioning member 7 can rotate relative to the outer rod. Therefore, this scheme in which the positioning member can rotate is also within the protection scope of this invention.

[0235] 2. Regarding the positional relationship between control component 2, adjustment component 4, positioning component 7, and triggering component, because these components are highly extensible and can vary greatly, there are many possible combinations of positional relationships. There is no absolute positional relationship; the main focus is on achieving the operating method and design concept expressed in this invention.

[0236] 3. Regarding the design that makes it difficult for the adjusting member 4 to detach after being inserted into the outer rod 1, this can be achieved in many ways, such as by limiting the positioning of the positioning groove 71, the positioning part 72, the positioning member 7, and / or the control member 2 themselves, and limiting the adjusting member 4 with their derivative parts. This method is something that those skilled in the art can solve, so similar issues will not be described in detail. For example, in Embodiment 1, the rotating member 82 is used to engage between the rotating boss on the displacement member 41 and the positioning groove 71 to ensure that the adjusting member 4 detaches from the outer rod 1.

[0237] 4. When the displacement member 41 deforms, a certain amount of deformation space needs to be reserved in the internal space for the displacement member 41. This can be done by reserving deformation space for the displacement member according to the actual situation. This can solve the problem of backward movement caused by deformation when deformation occurs. For example, in embodiment 1, a deformation groove 231 is provided on the extension rod 23 to solve the problem of backward movement caused by deformation when the displacement card protrusion 411 passes through the core protrusion 713.

[0238] 5. Regarding the issue of preventing the control lever 21 from moving left or right, corresponding locking protrusions are provided on the outer rod, and corresponding locking protrusions are also provided on the control lever 21, which can serve to prevent rotation. As for the maximum upward and downward movement limits of the control lever 21, this can be achieved simply by providing corresponding locking protrusions inside the outer rod. Therefore, the specific positions of the maximum upward and downward movement limits can be determined according to the actual situation.

[0239] 6. When the control element 2 releases the core by moving upwards, it can function normally between the control element 2 and the trigger assembly 6 even without the auxiliary reset element 31. The control element 2 can be reset by its own weight. It is necessary to ensure that the friction in the part of the outer rod 1 related to the sliding of the control element 2 is low, and that the control element 2 itself has a certain weight; this will result in better performance. However, for more stable operation, it is better to use the auxiliary reset element 31. The elasticity of the auxiliary reset element 31 does not need to be too large; it only needs to be sufficient to reset the control element 2.

[0240] 7. There are two ways to pull out the core, and they can coexist with triggering the core retraction. When using an internal structure, the solution of Example 1 is better. When it needs to be exposed to consumers, the solution of Example 3 can be used. When it is necessary to use pressing to pull out the core, the solution of Example 2 can be used. Of course, there are many other specific combinations, and there are still details that can be optimized. However, any modifications and improvements made without departing from the design concept and principle of this invention should also be considered within the scope of protection of this invention.

[0241] 8. In the description of this invention, there are many concepts of positional relationships, and the positional relationships implied by the same component are also multiple. It should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on different embodiments and different drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0242] 9. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0243] 10. The positioning groove 71 does not contain only the aforementioned channels. For example, there is also a core return channel between the core-exiting boss 713 and the core-receiving switching wall 711. Such normal channels will not be specifically described. It should be understood that the channels in the positioning groove are intended to allow the displacement component 41 and its related modified components to pass through.

[0244] 11. The structure of the triggering component in this invention is merely an example structure of this invention. Structures that can achieve similar effects should also be considered within the scope of protection of this invention.

[0245] 12. The contact part of the pen refill is determined according to the actual needs of the structure. For example, in Embodiment 1, the pen refill contacts the bottom of the positioning member, while in Embodiment 2, it contacts the adjustment contact part 42 of the adjustment member, and in Embodiment 3, it contacts the positioning part 72.

[0246] 13. When the control lever is operated alone without using the "trigger component", a component similar to the trigger cover 63 should still be added to the outer lever to cooperate with the outer lever. This component similar to the trigger cover 63 can be integrated with the outer lever, so it does not need to be explained separately. The component similar to the trigger cover 63 also has a through hole in the middle. The control lever can be exposed through the through hole and can be touched by a person, as shown in similar embodiment 4.

[0247] 14. Regarding the angles between the retractable switching wall 711, the switching long wall 71B, the retractable limiting wall 712, the lead-out sliding wall 7131, the control switching wall 212, the retractable auxiliary wall 717, and / or the lead-out guide wall 7132 and the horizontal line, the angles are generally between 15° and 80°. The retractable limiting wall 712 can be 90° or other degrees; generally, degrees around 45° are more ideal, such as 50°, 40°, 55°, 60°, 58°, 42°, 35°, and / or 65°, and so on. The specific angle limitations are mainly determined by the pen's lead-out stroke and the pen's retractable stroke, because the size of the angle will... The vertical distance between the two endpoints of the wall determines the efficiency of the displacement component 41. This vertical distance directly affects the pen's lead extension and retraction strokes. Therefore, the included angle depends on the type of tool used, such as a fountain pen, pencil, ballpoint pen, or gel pen, because each tool requires different lead extension and retraction strokes. The efficiency of the displacement component 41 also varies when facing different walls. Therefore, the included angle between all the walls and the horizontal line depends on the actual situation, ensuring that the displacement component 41 can pass smoothly throughout the entire operation while meeting the lead extension and retraction stroke requirements of the tool.

[0248] 15. The inventive concept of this invention can be applied not only to the pen manufacturing field, but also to the exposure and storage of the usage parts of other small tools.

[0249] 16. For ease of practical operation, the operation method described in this invention is to keep the outer rod stationary and move the adjusting or positioning component to produce and retract the core. This is because the outer rod has the largest exposed area and is the easiest to fix. In use, it can generally be held directly by the web of the hand. Conversely, it is also possible to keep the adjusting and positioning components stationary and move the outer rod to control the core production and retraction.

[0250] 17. Regarding the order of component installation, it will vary between each embodiment, depending on the structure of the outer rod and whether positioning components and triggering components are used. Generally speaking, after adding a pen-changing section to the outer rod, regardless of how the matching structure of the upper half of the outer rod is installed, the tool body and the reset component are installed into the outer rod from bottom to top, followed by the pen-changing section. Of course, depending on the actual situation, installation from top to bottom can also be used. However, since most of the core structure is located in the space at the rear, the bottom-up installation method is more suitable for replacing the tool body.

[0251] 18. You can also add some structures to prevent the positioning parts from rotating, such as adding an anti-rotation boss 13 to limit the left and right rotation of the positioning parts.

[0252] 19. After the positioning component is installed, it can be prevented from moving up and down by triggering the cover and limiting ring 12 or by limiting the outer rod itself, thereby ensuring the accuracy of operation.

[0253] 20. Regarding the lengths and positional relationships within the positioning grooves of the core-receiving switching wall 711, core-receiving auxiliary wall 717, switching long wall 71B, core-receiving limiting wall 712, core-exit sliding wall 7131, control switching wall 212, and / or core-exit guide wall 7132, the primary focus is on ensuring the efficiency and fault tolerance of the displacement component 41. For example, the horizontal distance between the endpoint of the core-exit sliding wall 7131 near the core-exit point B and the endpoint of the core-exit limiting wall 716 near the core-exit sliding wall 7131 should be greater than the width of the displacement component, thereby ensuring the upward or downward movement of the displacement component. During the movement, it can stably contact the core-receiving auxiliary wall 717; the straight-line distance between the end point of the core-exit sliding wall 7131 away from the core-exit point B and the switching long wall 71B should be greater than the outer diameter of the displacement member 41, so as to ensure that the displacement member can pass smoothly; and the horizontal distance between the end point of the core-exit sliding wall 7131 away from the core-exit point B and the end point of the core-exit limiting wall 716 near the core-exit sliding wall 7131 should be greater than the width of the displacement member, so as to ensure that the displacement member can stably contact the core-exit sliding wall 7131 during the upward or downward movement; and so on.

[0254] 21. To facilitate the replacement of the tool body, the front end of the outer rod can also be separated into a pen-changing section. If the outer rod is chosen to be separated into a pen-changing section, then under normal circumstances, the adjusting part does not need to be separated into a pen-changing section, especially when the core is pressed out. At this time, the adjusting part is located inside the outer rod and also needs to be responsible for resisting the tool body. Therefore, if a pen-changing section cannot be provided, it is more appropriate to separate it from the outer rod.

[0255] 22. Fitting Instructions: Most parts can be fitted together using threads, snap-fit, magnetic attraction, adhesive, socketing and / or third-party accessories. Other new materials or technologies can also be used, such as welding, or using elastic objects to assist in the fitting.

[0256] 23. There are many possibilities for the position of the adjustment hole mentioned above, because the structural concept of the present invention is relatively flexible and is not limited to a certain solution. As shown in the embodiments 1 to 4, the part that the tail of the tool body abuts is not exactly the same. However, the position of the adjustment hole is definitely determined by the position of the tail of the tool body, and the position of the adjustable base is based on the position of the adjustment hole. The inventive concept of this adjustment hole and adjustable base can also be applied to other similar products.

[0257] 24. The adjustable base needs a certain length of travel to provide ample space. When the adjustment hole position is insufficient, a certain space can be made through the structure behind the adjustment hole. Therefore, the structure behind the adjustment hole needs to provide sufficient adjustment through holes to facilitate the adjustment of the length of the adjustable base. For example, in embodiment 3, the positioning component provides ample length space for the adjustable base and also provides threaded engagement to further improve stability.

[0258] 25. The length of the external adjustment tool is customized according to actual needs. Therefore, the commonly used length markings are also customized based on these needs. For example, in the pen refill field, the commonly used specifications are G2 and G5. The external adjustment tool will only have two markings, G2 and G5. However, the G2 and G5 markings on the external adjustment tool are not simply the actual lengths of the original G2 and G5 pen refills. This is because when using the external adjustment tool, the pen changing section is detached from the outer rod or adjustment component. At this time, the internal space of the outer rod or adjustment component cannot fully accommodate the pen refill. Therefore, the reference point for the external adjustment tool's markings becomes the bottom of the outer rod or adjustment component. The length of the pen changing section should be deducted, and the internal structural state during adjustment needs to be standardized, such as when the pen is retracted or the displacement component is in the refill retraction state. 41. When the tool is pushed upwards to the top of the positioning groove, adjustments are made. The length of the scale line on the external adjustment tool should be the required length minus the length of the pen changing part, and then minus the error length of the set state. This error length can be a negative number. For example, if the pen refill is installed in the normal position of the outer rod and the pen changing part, and the internal structure is adjusted in the refill state, the refill needs to be exposed for a certain stroke. In this case, the error length is equal to the exposed stroke of the pen refill. Therefore, this error length needs to be subtracted, and the error length is a positive number, thus ensuring the accuracy of the scale line. If the set adjustment state is the refill state, the pen refill needs to be retracted into the pen changing part for a certain stroke. In this case, the error length is equal to the retracted stroke. Therefore, this error length needs to be added, and the error length is a negative number.

[0259] You can also directly mark the length scale lines of ordinary actual distances, allowing users to calculate and adjust them themselves; this can also increase the application scenarios of external adjustment tools. However, for targeted use, the more targeted scale lines such as G2 and G5 are sufficient for consumers to accurately adjust the internal length.

[0260] 26. When the control switching wall is not used, the switching long wall or the core-collecting auxiliary wall should be extended upwards or downwards by a certain distance to ensure that it can cover the area directly above or below the limiting boss; thus ensuring that when the displacement component or its replacement component passes through, it can successfully bypass the influence range of the limiting boss, thereby ensuring that the lifting scheme one can be realized normally; while the limiting fall slope can reduce the coverage requirement of the switching long wall or the core-collecting auxiliary wall, because the limiting fall slope can provide a certain slope guidance effect.

[0261] 27. In some embodiments, the positioning element 7 and the trigger cover 63 can be manufactured as a single unit according to actual conditions, thereby saving mold costs and installation procedures; similarly, the integrated production of other components is also a situation that can be reasonably deduced and improved by those skilled in the art.

[0262] 28. As can be seen from the embodiments of the present invention, the structure of the present invention is highly flexible, with a huge space for modification and design. At the same time, the technical effects that can be achieved are also huge, and the cost can be kept under control, making it fully commercially viable for mass production. Therefore, the present invention also protects the design concept, operation concept and operation method of the present invention. Any modifications or equivalent variations and alternative designs to the present invention should fall within the protection scope of the present invention.

[0263] 29. When using the lifting core-gathering method, because the maximum downward movement limit is used, in most cases, if a positioning component is used, the positioning component is installed into the outer rod from top to bottom together with the control component; then, due to the internal structure of the outer rod, for example, a limit ring platform 12 is added to limit the maximum downward movement limit; while the method of using the connecting part 11 is used, because the connecting part is broken off from the outer rod, some components are installed into the outer rod from top to bottom: such as some components related to the trigger assembly, while other components are installed into the outer rod from bottom to top, such as the adjusting component, the positioning component, and the auxiliary reset component.

[0264] 30. To ensure that the rotating component can counteract the negative interference caused by gravity, it is best to adjust the structure of the adjusting component itself. For example, adding a clamping structure to the adjusting component to clamp the rotating component from the front and back would eliminate the need for the rotating component to rely on the clamping between the adjusting component and the positioning component. This would result in higher stability and significantly reduce the accuracy requirements of the displacement part 821. There are many other ways to better counteract gravity on the rotating component, such as: 1. Adding rough texture to the annular surface of the rotating boss 412 to increase the friction between the rotating component 82 and the rotating boss 412, thereby counteracting the negative impact of gravity; 2. Adding elastic components to restrict the rotating component; 3. Using magnets to provide magnetic attraction to the rotating component to counteract gravity interference; 4. Increasing the friction of the positioning groove; 5. Using a multi-level structure on the positioning groove to prevent the rotating component from moving back; 6. Adding stepped restrictions to the displacement part 41 to constrain the rotating component.

[0265] 31. Because the structure of this invention can be reversed, it can be installed upright and the core can be pulled out by lifting, or it can be installed backwards and the core can be pressed back up by pressing the tail. Therefore, the upward or downward movement in this invention will change according to the main orientation of the specific scheme. There is no requirement for the adjusting member to move upward in order to release the core. When the tail is pressed back up to release the core, the adjusting member moves downward in the opposite way in order to release the core.

[0266] 32. The switching long wall 71B itself has two main functions: first, to assist in core ejection, and second, to assist in core take-up. These two seemingly opposite functions can exist individually or simultaneously, depending on the actual needs. For example, in order to be more stable and improve the fault tolerance rate, after the core take-up assisting function of the switching long wall 71B in embodiment 4 is replaced by the core take-up auxiliary wall 717, the switching long wall 71B is only responsible for assisting in core ejection. In embodiment 5, since it does not need to assist in core ejection, it only needs to provide the function of assisting in core take-up.

[0267] 33. In order to further improve the stability of the control component 2, a control groove is specially designed to accommodate the control lever 21. It can be extended downward or upward by a certain distance to form a control deep groove 7151. The head of the control lever 21 is also extended. Even when the control component 21 is in the triggered state and moves upward or downward to the maximum distance, the head of the control lever 21 will remain partially located in the control deep groove 7151. Therefore, when the displacement component 41 falls back, no void will be formed in the positioning groove, thus ensuring the stability of the overall operation.

[0268] 34. The aforementioned limiting boss 211 is a part of the control rod 21. The limiting boss 211 itself replaces the function of the limiting part of the control rod 21. However, this structure itself has great significance and cannot be regarded as just a simple extension of the control rod 21. Because the function of the entire invention has been greatly upgraded due to the appearance of the limiting boss 211, it has been expanded to obtain multiple different core-gathering methods. It is a key technical point for realizing lifting core-gathering and pressing core-gathering. The return auxiliary slope 213 further supplements and expands the limiting boss 211, making its functions more abundant. Making the limiting boss 211 an independent accessory or replacing it with a similar structure are all equivalent substitutions. Equivalent substitutions of other similar parts of the present invention should also be considered within the scope of protection of the present invention.

[0269] 35. Regarding the definition of "bypassing" above, it means taking the core exit point B as the starting point and circling around the limiting boss 211, such as: circling half a circle around the limiting boss 211 upwards or downwards, and circling to the other side of the limiting boss 211 corresponding to the core exit point B, thereby leaving the original core exit point B and thus realizing core collection.

[0270] 36. Regarding the definition of "crossing over" mentioned above, it means moving over the body of the limiting boss 211, starting from the core exit point B. Because the limiting boss 211 itself serves as a temporary restraint, the adjusting component can cross over the limiting boss 211 using auxiliary methods such as a fall-back ramp. However, for safety reasons, the adjusting component should preferably not start crossing over the limiting boss 211 from the core exit point B. It is best to cross over it from above or below the core exit limiting boss. Specifically… Whether it is above or below depends on the orientation of the positioning groove in the chosen scheme, which in turn depends on whether a lifting or pressing scheme is used. For example, first, the core exit point B is moved around to the top or bottom of the limiting boss 211. Then, by the force of the reset component, it rebounds and rises or falls. When it contacts the top or bottom of the limiting boss 211, the displacement component 41 passes over the limiting boss 211 through the fall-back auxiliary slope, thereby reaching the other side opposite to the fall-back auxiliary slope, thus achieving core collection.

[0271] 37. The external adjustment tool is also equipped with scale lines related to the product. These scale lines are determined by the distance between the bottom surface of the outer rod or adjustment part after removing the pen-changing part and the bottom surface of the adjustable base, and the distance between the actual length of the tool body of different specifications. This is because the actual length of the tool body of different specifications and the length of the pen-changing part are constant after production, and are within a very small error range. The distance between the exposed and retracted parts of the tool body can also be parameterized and, once set, is also a constant value.

[0272] When the adjusting part and the outer rod are in the retracted state, the actual length of the tool body + the distance the tool body is retracted into the pen changing part - the internal distance of the pen changing part = the distance between the bottom surface of the outer rod or adjusting part after removing the pen changing part and the bottom surface of the adjustable base;

[0273] When the adjusting component and the outer rod are in the core-out state, the actual length of the tool body - the distance of the tool body protruding from the pen-changing part - the internal distance of the pen-changing part = the distance between the bottom surface of the outer rod or adjusting component after removing the pen-changing part and the bottom surface of the adjustable base;

[0274] When the external adjustment tool extends into the outer rod or adjustment rod and contacts the adjustable base, the distance between the head of the external adjustment tool and the bottom surface of the outer rod or adjustment component after removing the pen-changing part is equal to the distance between the bottom surface of the outer rod or adjustment component after removing the pen-changing part and the bottom surface of the adjustable base.

[0275] Based on different states and different tool bodies, the distance between the bottom surface of the outer rod or adjustment part after removing the pen-changing part and the bottom surface of the adjustable base can be clearly defined. According to this rule, we can directly mark on the external adjustment tool the distance between the bottom surface of the outer rod or adjustment part after removing the pen-changing part and the bottom surface of the adjustable base calculated for different tool bodies under different states.

[0276] To facilitate labeling and prevent consumer confusion, it is best to label the scale lines indicating the required length of the different tool bodies when the core is being extended or retracted.

[0277] For example, the end of the external adjustment tool can be labeled "Please adjust in the lead-out state" or "Please adjust in the lead-in state"; then the scale lines correspond to the scale lines of different tool main product specifications, and the product specification abbreviation or number is written directly next to the scale lines. If it is a number defined by the merchant, then the corresponding instruction manual should also be attached.

[0278] In this way, consumers do not need to remember so many related parameters to calculate the distance to which to adjust when making adjustments, which greatly improves the practicality and convenience of the adjustability.

[0279] The above is an explanation of the settings for the external adjustment tool based on the use of a pen-changing unit. Adjustment can also be made from the other end of the overall structure. The calculation method and principle are similar and close, and the specifics are the same as above.

[0280] 38. The invention has a clever and perfect design structure, a clear design concept and idea, rich functions, and huge market potential. The main body of the tool is not only compatible with various pens, but also with other products that require this function, such as: lipstick, hand knife, key, screwdriver, eyebrow pencil, ear pick, medicine box, eraser, switch or earphone.

[0281] 39. The core function of the aforementioned reset component is to provide a continuous unidirectional force to the outer rod and the adjusting component. This force is typically achieved through a compressive elastic element, or it can be achieved through magnetic repulsion. Because the fundamental purpose is to provide a continuous unidirectional force, a continuous unidirectional force can also be provided through a tensile elastic element or magnetic attraction at the opposite position. Therefore, the reset component offers great flexibility in its design. However, regardless of the design, as long as the function is to provide a continuous force, it should be equivalent to the function of the reset component of this invention.

[0282] 40. If the above-mentioned switching slope is not used and a cover is added to the outer rod, it can be selected whether to change the installation to the cover. If it is changed to the cover, it will be beneficial to production. Therefore, considering the actual production needs, other parts of the structure can also be added with accessories as appropriate, and some structures can be changed to the new accessories or other accessories.

[0283] 41. The explanation for the relative stability of the two positional states achieved by the aforementioned adjusting component through the positioning groove, reset component, and control component is as follows: The reset component, through the transmission of the tool body, indirectly provides a continuous force to the adjusting component. The positioning groove has a dynamic and static displacement fixed relationship with the adjusting component. The adjusting component determines the core delivery or core retraction state by moving its position within the positioning groove. Switching between the two positional relationships requires the adjusting component to move and switch within the positioning groove. The reason it is described as a dynamic or static displacement fixed relationship is that when the adjusting component is located at the core retraction position of the positioning groove, it is in a static state, and at this time, only the positioning groove... The relationship between the adjusting component and the positioning component is complex. When the adjusting component is at the core exit point of the positioning groove, it is a kind of dynamic positional relationship. This is because the core exit point is jointly constructed by the control component and the core exit boss in the positioning groove. Although the core exit boss is relatively fixed, the control component is dynamically movable. The existence of the core exit point can be dynamically determined by the control component. When the control component moves up or down, the core exit point will lose its original function and will not be able to effectively fix the adjusting component. At this time, the adjusting component will return to the core receiving point. When the control component returns to its original position, the adjusting component can effectively stay at the core exit point when it moves to the core exit point again.

[0284] 42. The main function of the positioning part 72 is to replace the positioning part 7 in contacting the tool body 5, so that the tail end of the tool body 5 can be limited. Then, the core taking and core delivery can be accurately controlled by adjusting the displacement of the adjusting part. Therefore, the positioning part 72 can be integrally formed with the outer rod, or it can be separated into an independent accessory and installed into the outer rod as an accessory.

[0285] 43. To facilitate production, the required rotating boss can be installed on the adjusting part as a separate accessory.

[0286] 44. Under certain circumstances, the height of the core ejector boss 713 is lower than the depth of the positioning groove. This situation is generally used when auxiliary structures such as switching long walls are not used, and the core ejector boss is bypassed to enter the core ejector point B. In order to bypass the core ejector boss better, and at the same time, to prevent accidental operation that causes the displacement component 41 to fall out of the positioning groove, the height of the core ejector boss is appropriately reduced to ensure an increase in effect.

[0287] 45. The structure of this invention has many possible variations. Therefore, the fit and position of the various components, the actual operating parts, the parts that directly contact the structure, whether the pen replacement part is located on the outer rod or the inner rod, and the different application scenarios of the cover, as well as the structural variations of the outer rod, all depend on the actual situation. The following are some variations that need attention:

[0288] 1. The tail of the tool body can be the bottom of the positioning component, the adjusting component's adjusting contact part, or the positioning part of the outer rod. Correspondingly, when the tail of the tool body abuts the bottom of the positioning component or the positioning part of the outer rod, the movement of the adjusting component directly determines the exposure and retraction of the tool body. The reset component and the front end of the tool body are also basically located inside the adjusting component. When the tail of the tool body abuts the adjusting contact part of the adjusting component, the movement of the adjusting component indirectly determines the exposure and retraction of the tool body. In this case, the reset component and the front end of the tool body are basically located inside the outer rod.

[0289] Second, the auxiliary reset component can be located between the control component and the cover, or between the positioning component and the control component, between the control component and the outer rod, between the control component and the trigger cover, or between the control component and the adjustment component; when located in different positions, many corresponding structures will also change accordingly.

[0290] Third, the operating position is also very variable, which can be front-end operation, tail-end operation, side operation, 360-degree trigger operation, pen clip operation, pressing operation, reverse push operation, or side push operation; and the pressing operation is further divided into multiple situations; some compatibility relationships listed in this invention are only preliminary classifications, and may be added or reduced according to the actual structural changes.

[0291] Fourth, the control components are highly variable. The shape and structure of the control components are also very complex. The changes in the control components are determined by factors such as the change of the positioning groove, the different required operating methods, and the installation orientation. To a certain extent, the stability of the control components can also be improved by adding some stabilizing structures.

[0292] V. The versatility of the push rod: The push rod can be produced as an integrated unit, fixed or rotated, depending on factors such as process, production, and the desired operational effect. Rotational installation can be achieved by fixing one end and rotating on one side, or fixing in the middle and rotating at both ends.

[0293] VI. Versatility of the triggering component: The triggering component can be selected as needed to move the limiting member or trigger the cover to move, or it can move through the trigger rod. The triggering forms of this invention are very varied, and this invention only lists a part of them.

[0294] VII. The outer rod is versatile. The tail can be replaced by a cover or a rotating fastener, or a connector, a push rod, a pen clip, a pen changing part and / or a positioning part can be added.

[0295] 8. The adjusting components are highly variable, with a very wide range of adjustments, achieving different functions and effects. They can be partially exposed above the upper end of the outer rod, partially exposed below the lower end, partially exposed on the side, or completely hidden inside the outer rod. Furthermore, the shape and structure of the adjusting components also vary accordingly. For example, many of the adjusting components in the embodiments look completely different from the same part because the range of variation is so large, and the functions and effects they achieve are also very powerful. Based on the variability of the adjusting components, a wide variety of core-exiting and core-receiving operations can be achieved, and multiple different core-exiting operations or multiple different core-receiving operations can coexist. Although the adjusting components are so varied, they can all be summarized and expressed as the same component. The variability is simply an adaptive adjustment based on actual conditions and needs.

[0296] 46. ​​The adjustment component and the pen changing part can be connected by magnetic attraction, snap-fit, or threaded connection. The displacement direction and contact point of the control rod 21, which is connected by magnetic attraction and rotatable snap-fit, will determine and affect the triggering force. In order to trigger better, although the control rod 21 will contact the displacement limiting component 41, the main bearing point should be designed on the core-exiting boss 713 in the positioning component groove. The core-exiting boss 713 mainly bears the force of the reset component 3, ensuring that when the control rod 21 is pulled out to release the limit and trigger the core retraction, the required force is only a contact force.

[0297] 47. When the fastener is engaged, it can ensure that the adjustment part can rotate relative to the pen changing part, thereby facilitating the engagement between the adjustment part and the positioning groove.
