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, CN202011516 describes a 360-degree trigger structure and a pen using this structure. This technology enables the pen to trigger and retract in 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: 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. 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 by moving the control component, the restriction of the control component on the displacement component can be released, and the component can return to the core-gathering point, thereby achieving core gathering. By controlling the movement of the adjusting component, the displacement component is moved from the core receiving point to the core exit point, thus achieving core exit.

[0008] The switching from the core output state to the core recovery state can be achieved in fourteen ways: 1. Movement control for core retraction: By influencing the movement of the control component through external force, the displacement component is made to break free from the constraint of the control component. Then, the displacement component will be moved by the reset component, thereby realizing core retraction. II. Triggering Core Retraction Scheme 1: The transmission of the trigger component causes the control component to move, causing the displacement component to break free from the control component's restriction. The displacement component will then be affected by the reset component and move, thereby achieving core retraction. III. Lifting and Core-Gathering Scheme 1: The external force control adjustment component moves upward, and through the switching long wall and reset component on the positioning groove, the displacement component bypasses the limitation of the limiting boss and returns to the core-gathering position; IV. Lifting and Core-Collecting Scheme Two: The external force control adjustment component moves upward, and reaches the upper part of the limit boss by switching the long wall. The external force is released, and the displacement component returns to the core-collecting position after passing the limit of the control component through the return auxiliary slope and reset component on the control rod. V. Pressing and Core-Collecting Scheme 1: The external force controls the adjustment component to move downward. Through the switching long wall on the positioning groove, the displacement component bypasses the limitation of the limiting boss and returns to the core-collecting position through the reset component. VI. Pressing and retracting scheme two: The external force control adjustment component moves down and reaches below the limit boss by switching the long wall. When the external force is released, the displacement component returns to the retracting position after passing the limit of the control component through the return auxiliary slope and reset component on the control rod. VII. Core-collecting scheme 1: External force presses one end of the push rod to contact the displacement component, causing the push rod to push the displacement component away from the core-exiting platform; when the displacement component is separated from the core-exiting platform, it is subjected to the action of the reset component, and the displacement component moves down to the core-collecting point. 8. Push-rod core-collecting scheme two: External force lifts one end of the push-rod away from the displacement component, causing the other end of the push-rod to be affected by linkage and squeeze the displacement component to disengage from the core-exiting platform; when the displacement component disengages from the core-exiting platform, it is subjected to the action of the reset component and moves down to the core-collecting point. 9. Triggering Core Retrieval Scheme Two: The transmission of the trigger component causes the control component to move, causing the displacement component to break free from the restriction of the core ejection platform. Then, the displacement component will be affected by the reset component and move, thereby realizing core retrieval. 10. Lifting and core-gathering scheme three: The external force controls the adjustment component to move upward. Without using the switching ramp, the displacement component deforms backward. When the deformation reaches a certain extent, the external force is released. Under the influence of the reset component, the displacement component will pass through the core-out plate, but will not cooperate with the core-out plate. Instead, it will fall directly into the core-gathering point. XI. Reverse Push Core Collection Scheme: Keep the outer rod stationary, and use external force to pull the adjusting component down or up. Through the reverse push auxiliary slope, the displacement component is released from the restriction of the core exiting platform or core exiting boss, and thus returns to the core collection point. 12. Pressing and collecting core scheme three: Press the trigger ring with external force to squeeze the trigger cover or trigger element, thereby squeezing the trigger cover or trigger element to squeeze the control element. The control element causes the displacement element to move inward, thereby disengaging the displacement element from the core outlet. The reset element returns the displacement element to the core collection point.

[0009] Thirteen, Side-push core-gathering scheme one: By controlling the side-push part to move down by external force, the displacement part will continue to move down, and then through the core-gathering auxiliary wall on the positioning groove, the displacement part will bypass the limitation of the limiting boss and return to the core-gathering position through the reset part; Fourteen, Side-push core-gathering scheme two: External force controls the side-push part to move down, reaching below the limiting boss through the core-gathering auxiliary wall. Releasing the external force allows the displacement part to pass the control component's limit and return to the core-gathering position via the return auxiliary slope and reset component on the control rod.

[0010] The above-mentioned three methods of lifting and retracting the core, one of the two types of lever retracting, reverse push retracting, pressing and retracting, and triggering retracting can coexist; The above-mentioned lifting and core-gathering scheme 1, lifting and core-gathering scheme 2, movement control core-gathering, reverse push core-gathering scheme, and trigger core-gathering scheme 1 can coexist; The above-mentioned pressing core-retracting scheme 1, pressing core-retracting scheme 2, movement control core-retracting, reverse push core-retracting scheme and trigger core-retracting scheme 1 can coexist.

[0011] The above-mentioned side-push core-retrieving scheme 1, the movement control core-retrieving scheme 1, and the trigger core-retrieving scheme 1 can coexist.

[0012] Alternatively, the side-push core-retrieving scheme 2, the movement-controlled core-retrieving scheme, and the trigger-based core-retrieving scheme 1 can coexist.

[0013] The switching from the core-receiving state to the core-discharging state can be achieved through at least the following fourteen methods: I. Core Extraction Scheme 1: The external force control adjustment component moves upward and moves through the switching long wall on the positioning groove to the space between the core extraction boss and the control component, stopping at the core extraction point; II. Pulling out the core, scheme two: Keep the outer rod still, and use external force to control the adjustment component to move upward. When the displacement component passes the core-exiting boss, it will pass the core-exiting boss through the core-exiting auxiliary slope and the deformation and bending ability of the displacement component, and reach the core-exiting point. 3. Core lifting scheme 3: External force control adjustment component moves upward. When the displacement component moves from the core receiving point, it is affected by the core exit guide wall and enters the core exit channel. Then, it reaches above the core exit point by switching the long wall. At this time, when the external force is released, the displacement component will fall back to the core exit point. IV. Pressing out core scheme one: The external force control adjustment component moves down and moves through the switching long wall on the positioning groove to between the core ejection boss and the control component, stopping at the core ejection position; V. Pressing out the core, scheme two: Keep the outer rod still, and use external force to control the adjustment component to move down. When the displacement component passes the core-exiting boss, it will pass the core-exiting boss through the core-exiting auxiliary slope and the deformation and bending ability of the displacement component, and reach the core-exiting point. VI. Pressing out the core scheme three: The external force controls the adjustment component to move down. When the displacement component moves from the core receiving point, it is affected by the core exit guide wall and enters the core exit channel. Then, it reaches the top of the core exit point by switching the long wall. At this time, when the external force is released, the displacement component will fall back to the core exit point. VII. Core Extraction Scheme Four: The external force control adjustment component moves upward, and the displacement component moves directly from the core receiving point to the core extraction platform, where it engages with the core extraction platform, thus completing the core extraction; VIII. Core Extraction Scheme 5: The external force control adjustment component moves upward. The displacement component moves upward from the core receiving point and reaches the core extraction platform through the extension switching slope and / or blocking entry slope, and engages with the core extraction platform to complete the core extraction.

[0014] IX. Side-ejection core ejection scheme one: The side-ejection part is moved downward by external force, and moves between the core ejection boss and the control component through the switching long wall on the positioning groove, and stops at the core ejection point; 10. Side-pushing core ejection scheme two: The side-pushing part moves downward under the control of external force. When the displacement part passes the core ejection boss, it passes the core ejection auxiliary slope and / or the deformation and bending ability of the displacement part, and reaches the core ejection point. XI. Side-pushing core scheme three: External force controls the side-pushing part to move downward. When the displacement member moves from the core receiving point, it is affected by the core exit guide wall and enters the core exit channel. Then, by switching the long wall, it reaches above the core exit point. At this time, when the external force is released, the displacement member will fall back to the core exit point. 12. Side-press core ejection scheme 1: When the side-press component is moved backward by external force, the adjusting component will move downward along with the displacement component, thereby moving between the core ejection boss and the control component through the switching long wall on the positioning groove, and stopping at the core ejection position; Thirteen, Side-pressing core ejection scheme two: When the side-pressing component is moved backward by external force, the adjusting component will move downward along with the displacement component. Thus, when the displacement component passes the core ejection boss, it will pass the core ejection boss through the core ejection auxiliary slope and / or the deformation and bending ability of the displacement component, and reach the core ejection point. Fourteen, Side-press Core Exit Scheme Three: When the external force controls the side-press component to move backward, the adjusting component will move downward along with the displacement component. Thus, when the displacement component moves from the core receiving point, it is affected by the core exit guide wall and enters the core exit channel. Then, by switching the long wall, it reaches below the core exit point. At this time, when the external force is released, the displacement component will fall back to the core exit point.

[0015] Of the fourteen winding methods mentioned above, lifting winding and pressing winding should not coexist under normal circumstances. However, lifting winding or pressing winding can coexist with movement control winding and trigger winding on the same product. Two different lifting winding schemes and two different pressing winding methods can coexist. However, under normal circumstances, only one of the lifting winding or pressing winding schemes needs to be used.

[0016] Of the fourteen core ejection methods mentioned above, lifting and pressing core ejection should not coexist under normal circumstances. However, lifting core ejection scheme one or three can coexist with lifting core ejection scheme two, and pressing core ejection scheme one or pressing core ejection scheme three can coexist with pressing core ejection scheme two. Under normal circumstances, only one of the six core ejection schemes needs to be selected.

[0017] The above-mentioned lifting and core-gathering method can be implemented in at least two ways. One way is that after the auxiliary ramp on the control component and the positioning groove moves into place, the external force disappears, and the displacement component will fall back to the core-gathering position under the influence of the reset component. The second way is that after the auxiliary ramp on the positioning groove moves into place, the external force disappears, and the displacement component falls back to the core-gathering position under the influence of the reset component. Then, it passes over the control component via the auxiliary ramp on the control component and returns to the core-gathering position. The positions of the auxiliary ramps in the first and second methods are not the same, and the contact structure between the positioning component and the displacement component in the first and second methods is also not the same, depending on the actual operating scenario. The first method is mainly used when the positioning groove is located on the positioning component or inside the outer rod, while the second method is mainly used when the positioning groove is located on the outer rod.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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; 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.

[0022] 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. 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.

[0023] The core-receiving state is switched to the core-exiting state by lifting the core out: keeping the outer rod stationary, the 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.

[0024] A mechanical pen and its operating method are disclosed, comprising an outer rod, a reset component, a tool body, and an adjustment module; the adjustment module includes a control component, an adjustment component, and a positioning component. The positioning element is installed inside the outer rod, and the positioning element is provided with a positioning groove; The control component is equipped with a control lever; the tail of the tool body and the tail of the positioning component come into contact; The adjusting component is provided with a displacement component, which can move movably within the positioning groove; The positioning groove is provided with a core receiving switching wall, a switching long wall, and a core exiting boss; the core exiting boss is provided with a core exiting sliding wall; The bottom of the core-gathering switching wall is the core-gathering point. At this time, the main body of the tool remains completely hidden inside the adjusting component, and this is the core-gathering state. When the displacement component is located on the core ejection sliding wall, it will move in the tilting direction of the core ejection sliding wall due to the influence of the core ejection sliding wall and the reset component. Before it completely leaves the core ejection sliding wall, it will be limited by the control rod. Finally, the displacement component will stop on the core ejection sliding wall. At this time, the position where the displacement component stops is the core ejection point; this is the core ejection state. The control lever achieves the extended core-gathering method through the following two schemes: 1. The control rod is provided with a limiting boss, which restricts the displacement component instead of the control rod; when the core is retracted, the displacement component moves upward, and by switching the long wall and the reset component, the displacement component is released from the limitation of the limiting boss and returns to the core retraction position; 2. The control rod is equipped with a fall-back auxiliary slope. When the core is retrieved, the displacement member moves upward and leaves the space above the core-exiting boss by switching the long wall. Then, it jumps over the restriction of the control rod by the reset member and the fall-back auxiliary slope.

[0026] A mechanical pen and its operating method are disclosed, comprising an outer rod, a reset component, a tool body, and an adjustment module; the adjustment module includes a control component and an adjustment component. The control component is equipped with a control lever; The outer rod is provided with a positioning groove; the adjusting component is also provided with an adjusting contact part; the tail of the tool body and the adjusting contact part make contact; The adjusting component is provided with a displacement component, which can move movably within the positioning groove; An auxiliary reset component is provided between the control component and the adjustment component; The positioning groove is provided with a core receiving switching wall, a switching long wall, and a core exiting boss; the core exiting boss is provided with a core exiting sliding wall; The bottom of the core-gathering switching wall is the core-gathering point.

The control rod is provided with a limiting boss, which restricts the displacement component instead of the control rod; when the core is retracted, the displacement component moves upward, and by switching the long wall and the reset component, the displacement component is released from the limitation of the limiting boss and returns to the core retraction position; 2. The control rod is equipped with a fall-back auxiliary slope. When the core is retrieved, the displacement member moves upward and leaves the space above the core-exiting boss by switching the long wall. Then, it jumps over the restriction of the control rod by the reset member and the fall-back auxiliary slope.

[0027] As a preferred embodiment of the present invention: when the lifting and core-gathering scheme one is adopted, the control component is further provided with a control switching wall; a core-gathering channel is further provided between the limiting boss and the switching long wall and / or a core-gathering channel is further provided between the limiting boss and the control switching wall.

[0028] As a preferred embodiment of the present invention, when the second core-collecting scheme is adopted, a core-collecting channel is also provided between the control component and the switching long wall.

[0029] As a preferred embodiment of the present invention: when the positioning groove is provided on the outer rod, the outer rod is also provided with a core-receiving limiting wall; When the positioning groove is provided on the positioning member, the positioning groove is also provided with a core-receiving limiting wall or the inner wall of the outer rod is equal to the core-receiving limiting wall, which plays a limiting role.

[0030] As a preferred embodiment of the present invention: the control component is provided with a control lever; the displacement component achieves core collection through the following five methods: 1. Core-collecting scheme 1: The control rod is provided with a limiting boss; the limiting boss replaces the control rod to restrict the displacement component; during core collection, the displacement component moves up or down, and by switching the long wall, the displacement component bypasses the limitation of the limiting boss, thereby returning to the core-collecting point; II. Core-collecting scheme two: The control rod is provided with a limiting boss; the limiting boss replaces the control rod to restrict the displacement component; the limiting boss is provided with a return slope; the displacement component moves up or down, and reaches the space above or below the limiting boss by switching the long wall, and then crosses the limitation of the limiting boss by the return slope, thus returning to the core-collecting point; III. Core-collecting scheme three: The control rod is also provided with a limiting boss and a control fall slope; the limiting boss replaces the control rod to restrict the displacement component; after the control rod moves down, the displacement component is affected by the force of the reset component and moves upward, and the control fall slope assists the displacement component to return to the core-collecting position.

[0031] IV. Movement Control for Core Retraction: By forcing the movement of the control component through external force, the displacement component is freed from the restriction of the control component. Then, the displacement component will be affected by the reset component and move downward or upward, thereby realizing core retraction. 5. Backward Push Core Retraction: The displacement component and / or the core-exiting boss are also provided with a backward push auxiliary slope; keeping the outer rod stationary, an external force pulls the adjusting component downward, and through the backward push auxiliary slope, the displacement component is released from the restriction of the core-exiting boss, thus returning to the core-retraction point. The backward push auxiliary slope has a slope between 1 and 40°, and the backward push auxiliary slope requires the displacement component itself to have the ability to deform forward and backward.

[0032] The above five schemes can be independently divided into two opposite schemes depending on the direction of operation; The above-mentioned options 1, 2, 4 and 5 can coexist, exist individually, or be combined arbitrarily; Options three, four, and five can coexist, exist individually, or be combined arbitrarily. The reverse ramp is also an important parameter in triggering the core-retrieving scheme two, assisting in adjusting the actual contact force and friction between the core-ejecting platform and the displacement component. This is because triggering the core-retrieving scheme two is highly dependent on factors such as the friction and contact force between the core-ejecting platform and the displacement component, the deformation force of the displacement component, and the elasticity of the reset component and / or auxiliary reset component. The friction between the core-ejecting platform and the displacement component is mainly limited by the material, surface smoothness, and the specific slope of the reverse ramp. Therefore, the reverse ramp must be set precisely based on the actual conditions of the elasticity of the reset component and / or auxiliary reset component, the deformation force of the displacement component, the material and surface smoothness of the core-ejecting platform and the displacement component. This ensures that the contact force between the core-ejecting platform and the displacement component is greater than the elasticity of the reset component, and as small as possible while maintaining normal operation. This makes triggering the core-retrieving scheme two easier to achieve. The reverse push ramp is not very useful for triggering the core-retrieving scheme 1. Adding it would allow for another reverse push core-retrieving method, but for stability reasons, it is better not to add it. The original lifting core-retrieving and triggering core-retrieving or pressing core-retrieving and triggering core-retrieving is already sufficient to meet the usage requirements. Therefore, stability should be the priority.

[0033] As a preferred embodiment of the present invention, the outer rod is further provided with a triggering component, which affects the movement of the control component, thereby changing the triggering form, triggering direction, triggering force and triggering range of the control component.

[0034] As a preferred embodiment of the present invention, the triggering component can be implemented in at least the following three ways: 1. The triggering assembly includes a limiting member, a trigger ring, and a trigger cover; the limiting member passes through the trigger cover and is connected to a control member, and the control member moves with the limiting member; the trigger cover and the outer rod are connected to each other; the trigger ring is located between the limiting member and the trigger cover; a trigger auxiliary inclined ring is provided on the lower side of the limiting member, the upper side of the trigger ring, the lower side of the trigger ring, and / or the upper side of the trigger cover; the trigger cover can also be integrally formed with the outer rod, however, this method requires ensuring that the outer rod can be mass-produced normally and that the internal structure can be installed normally. 2. The outer rod is provided with a connecting body; the trigger assembly includes a limiting member, a trigger ring, and a trigger cover; the limiting member passes through the trigger cover and is connected to the connecting body, and the trigger cover passes through the connecting body and is connected to or abuts against the control member; when the trigger cover moves downward, the control member will also be pressed downward; the trigger ring is located between the limiting member and the trigger cover; a trigger auxiliary inclined ring is provided on the lower side of the limiting member, the upper side of the trigger ring, the lower side of the trigger ring, and / or the upper side of the trigger cover; 3. The triggering component includes a limiting member and a triggering ring; the limiting member passes through the outer rod and is connected to the control member, and the control member moves with the limiting member; the triggering ring is located between the limiting member and the outer rod; the limiting member, the triggering ring, and / or the outer rod are provided with triggering auxiliary inclined rings; All of the above solutions can achieve triggering core retraction: when the trigger ring receives any external force, it will be converted into vertical power, which will be transmitted to the control component through the limiting component or the trigger cover, thereby causing the control component to move up or down. At this time, the displacement component will be disengaged from the core exit point and return to the core retraction point through the force of the reset component. When adopting Option 3, the installation problem of the outer rod components can be solved through the following solutions: 1. The outer rod has a positioning groove. The adjusting part will eventually engage with the positioning groove, making it difficult to come out of the outer rod. All the components inside the outer rod are installed from bottom to top, and finally the adjusting part is installed to achieve the stability of the entire component. 2. The outer rod also needs to be provided with an additional installation opening, which is used to install auxiliary reset components, control components, adjustment components and / or positioning components; the installation opening can also be equipped with a matching installation cover to ensure the stability after installation; 3. The outer rod is equipped with a cover. By removing the cover, the upper channel of the outer rod can be opened. The components that need to be fixed are then installed into the outer rod from top to bottom. The outer rod is equipped with corresponding limiting components. Finally, the cover is installed, and then other triggering components are installed. IV. The outer rod is provided with a fixing through hole. All components are installed into the outer rod from bottom to top. Then, through the fixing through hole, the individual fixing accessories are installed to restrict the positioning component and fix it. Then the installation is completed. 5. After assembling the adjustment module, apply adhesive to the contact surface and then directly insert the outer rod. Once the adhesive dries, the fixing is complete.

[0035] As a preferred embodiment of the present invention: the solution for the displacement member to move left or right within the positioning groove can employ at least the following eight solutions, some of which can be combined: 1. The displacement component is provided with a movable groove, and a sliding ball is provided between the movable groove and the positioning groove; the sliding ball directly contacts the positioning groove instead of the displacement component. 2. The displacement component is further provided with a displacement locking protrusion, a sliding bead groove, or a rotating boss. A sliding bead is provided between the sliding bead groove and the positioning groove. A rotating component is also provided on the rotating boss. One end of the rotating component is sleeved on the rotating boss. The rotating component can rotate relative to the rotating boss. The other end of the rotating component is provided with a displacement part. The displacement part, the sliding bead, or the displacement locking protrusion directly contacts the positioning groove in place of the displacement component. The positioning component can translate or rotate relative to the outer rod. Third, the displacement component is further provided with a displacement locking protrusion, a sliding bead groove, or a rotating boss. A sliding bead is also provided between the sliding bead groove and the positioning groove. A rotating component is also provided on the rotating boss. One end of the rotating component is sleeved on the rotating boss. The rotating component can rotate relative to the rotating boss. The other end of the rotating component is provided with a displacement part. The displacement part, the sliding bead, or the displacement locking protrusion directly contacts the positioning groove instead of the displacement component. Furthermore, the displacement component itself has a certain left-right deformation bending ability and can bend to a certain extent, thereby satisfying the situation that the displacement component will move to the left or right when moving in the positioning groove, provided that the adjusting component itself does not move. Fourth, the displacement component is further provided with a displacement locking protrusion, a sliding bead groove, or a rotating boss. A sliding bead is also provided between the sliding bead groove and the positioning groove. A rotating component is also provided on the rotating boss. One end of the rotating component is sleeved on the rotating boss. The rotating component can rotate relative to the rotating boss. The other end of the rotating component is provided with a displacement part. The displacement part, the sliding bead, or the displacement locking protrusion directly contacts the positioning groove instead of the displacement component. Furthermore, the displacement component itself does not deform or bend to the left or right. When it needs to move to the left or right, the entire adjusting component rotates to the left and right accordingly. 5. The displacement component is separated from the adjusting component to form an independent part. The displacement component is also provided with a displacement locking protrusion, a sliding bead groove or a rotating boss. A rotating component is also provided on the rotating boss. One end of the rotating component is sleeved on the rotating boss. The rotating component can rotate relative to the rotating boss. The other end of the rotating component is provided with a displacement part. The displacement part, sliding bead or displacement locking protrusion directly contacts the positioning groove in place of the displacement component. The displacement component and the adjusting component are engaged by magnetic attraction, snap-fit, adhesive, threaded connection and / or third-party accessories, thereby realizing the rotation or translation of the displacement component relative to the adjusting component. VI. The displacement member is further provided with a rotating boss, and a rotating member is provided on the rotating boss. One end of the rotating member is sleeved on the rotating boss, and the rotating member can rotate relative to the rotating boss. The other end of the rotating member is provided with a displacement part, which directly contacts the positioning groove instead of the displacement member. Furthermore, the displacement member does not need to rotate left or right. When left or right movement is required, the rotating member can be rotated relative to the rotating boss. The rotating member and the rotating boss are connected by a damping engagement, that is, the rotating member can rotate relative to the rotating through hole, and at the same time, it can have the function of resisting gravity. 7. The displacement component is further provided with a rotating through hole, and a rotating component is provided inside the rotating through hole. The rotating component can rotate relative to the rotating through hole. The other end of the rotating component is provided with a displacement part, which directly contacts the positioning groove instead of the displacement component. One end of the rotating component is provided with a rotating boss, which is installed inside the rotating through hole. The rotating through hole and the rotating boss can be connected by adding texture to the surface or inner surface to form a damping fit through a snap-fit ​​method. That is, the rotating component can rotate relative to the rotating through hole and can also have the function of resisting gravity. 8. With the assistance of other third-party accessories, the displacement component can meet the requirements for left and right movement within the positioning groove.

[0036] As a preferred embodiment of the present invention, the solution for moving the displacement member from the core receiving point to the core exiting point within the positioning groove can adopt at least the following three solutions: 1. The core-exiting boss near the core-receiving end and / or the displacement member near the core-exiting end are provided with a core-exiting auxiliary slope. The displacement member itself has the ability to deform and bend forward and backward. When the displacement member passes the core-exiting boss, it can pass the core-exiting boss and reach the core-exiting point through the core-exiting auxiliary slope and the deformation and bending ability of the displacement member. 2. The core-exiting boss is also provided with a core-exiting guide wall on the side near the core-receiving point; a core-exiting channel is also provided between the switching long wall and the core-exiting boss; when the displacement member moves upward from the core-receiving point, it enters the core-exiting channel under the influence of the core-exiting guide wall, and then reaches the top of the core-exiting point through the switching long wall. At this time, when the external force is released, the displacement member will fall back to the core-exiting point. Third, the core-exiting boss is also provided with a core-exiting channel on the side near the core-receiving point; when the displacement member moves upward from the core-receiving point, it directly enters the core-exiting channel, and then reaches the top of the core-exiting point by switching the long wall. At this time, when the external force is released, the displacement member will fall back to the core-exiting point.

[0037] When the scheme of passing over the core-exiting boss by using the core-exiting auxiliary slope is adopted, the core-exiting boss can be provided with deformation slots. Only one side and the left and right sides of the core-exiting boss need to have deformation slots. In this way, the core-exiting boss has deformation capability, so the displacement component can pass over the core-exiting boss without deformation capability.

[0038] The three schemes described above can have their set direction changed depending on the actual operation method. Therefore, each of the above schemes has two variations, positive and negative. After extension, at least six schemes can be obtained. Furthermore, by adding auxiliary components such as side pushers, the possibility of schemes can be further extended.

[0039] As a preferred embodiment of the present invention: the positioning groove is further provided with a core-exit limiting wall and a core-receiving auxiliary wall; the core-exit limiting wall is mainly used to restrict the displacement member and prevent the displacement member from moving too far upward, thereby making it impossible for the displacement member to stop at the core-exit point; while the core-receiving auxiliary wall is used because after the switching long wall is blocked by the core-exit limiting wall, its length becomes shorter and it can no longer help the displacement member to lift and receive the core. Therefore, the core-receiving auxiliary wall can replace the original function of the switching long wall and continue to help the displacement member to receive the core by lifting and receiving the core.

[0040] As a preferred embodiment of the present invention, an auxiliary reset component is provided between the control component and the outer rod.

[0041] As a preferred embodiment of the present invention, the triggering component can be implemented in at least the following two ways: 1. The triggering assembly includes a limiting member, a trigger ring, and a trigger cover; the limiting member passes through the trigger cover and is connected to a control member, and the control member moves with the limiting member; the trigger cover and an outer rod are connected to each other; the trigger ring is located between the limiting member and the trigger cover; a trigger auxiliary inclined ring is provided on the lower side of the limiting member, the upper side of the trigger ring, the lower side of the trigger ring, and / or the upper side of the trigger cover; 2. The outer rod is provided with a connecting body; the trigger assembly includes a limiting member, a trigger ring, and a trigger cover; the limiting member passes through the trigger cover and is connected to the connecting body, and the trigger cover passes through the connecting body and is connected to or abuts against the control member; when the trigger cover moves downward, the control member will also be pressed downward; the trigger ring is located between the limiting member and the trigger cover; a trigger auxiliary inclined ring is provided on the lower side of the limiting member, the upper side of the trigger ring, the lower side of the trigger ring, and / or the upper side of the trigger cover.

[0042] As a preferred embodiment of the present invention, the outer diameter of the trigger ring is larger than the outer diameter of the outer rod.

[0043] As a preferred embodiment of the present invention, the 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.

[0044] As a further preferred embodiment of the present invention: the control component and the outer rod can only move up and down, but cannot rotate left and right, and there is a maximum limit for downward movement or a maximum limit for upward movement. The specific choice between the maximum limit for upward movement and the maximum limit for downward movement depends on whether the adjusting component is used to pull out the core or press out the core, and can be achieved by limiting the movement.

[0045] As a further preferred embodiment of the present invention, a trigger bevel is added to the lower end of the trigger ring.

[0046] As a further preferred embodiment of the present invention, the front end of the adjusting member or the outer rod can be separated into a pen replacement section for easy replacement of the pen refill and installation.

[0047] As a further preferred embodiment of the present invention: the smaller the surface friction of the control rod and / or trigger ring, the better; the core receiving channel is provided with a channel ramp on the side near the core exit, which can reduce unnecessary interference caused by production errors and further avoid unnecessary jamming.

[0048] As a further preferred embodiment of the present invention: the positioning groove is further provided with an anti-detachment boss, and a return channel is provided between the limiting boss and the anti-detachment boss or between the inner wall of the outer rod and the limiting boss. The outer diameter of the return channel and the core-collecting channel is larger than the outer diameter of the displacement locking boss, the sliding ball, and the displacement component located in the positioning groove; the function of the anti-detachment boss can also be directly transmitted through the outer rod. The inner wall can be used, and it does not necessarily have to be located on the positioning groove.

[0049] As a further preferred embodiment of the present invention: the positioning groove is provided with a multi-layered staggered design. The multi-layered staggered design means that the depth of the positioning groove is designed to be different according to the movement trajectory of the displacement component. The specific depth, and which parts are high and which parts are low, is that the core receiving point A is the highest. Then, the depth decreases all the way from the core receiving point A to the core exit point B. Then, the process from the core exit point B to the core receiving point A is first decreasing and then increasing. Specifically, after completely leaving the core exit point B, the depth continues to decrease within a certain distance. Then, the process of returning to the core receiving point A gradually increases.

[0050] As a further preferred embodiment of the present invention: when a positioning element and a trigger cover are used, the trigger cover and the positioning element can be manufactured as a single unit.

[0051] As a further preferred embodiment of the present invention, the reset member and the auxiliary reset member are formed by elastic material, elastic structure, repulsive force of magnetically attracted object, spring, spring sheet, repulsive force of magnetically attracted material, elastic material and / or combination or individual.

[0052] As a further preferred embodiment of the present invention, the reset member and the auxiliary reset member can also replace the continuous force required for the original orientation from the opposite position by means of a stretchable elastic element or magnetic attraction.

[0053] As a further preferred embodiment of the present invention, the core function of the reset member and the auxiliary reset member is to provide a continuous force to the tool body and / or the adjustment member.

[0054] As a further preferred embodiment of the present invention: the positioning member is further provided with a control groove for accommodating the up-and-down movement of the control rod. The control rod passes through the control groove to restrict the displacement latch, sliding bead, rotating member, or displacement member part located in the positioning groove from detaching from the core exiting sliding wall; it is preferable that the control groove and control rod extend to the same horizontal line as the core receiving point, so that even if the control rod moves upward due to the influence of the triggering component, when the displacement latch, rotating member, sliding bead, or displacement member located in the positioning groove releases the control rod at the moment of triggering and enters the core receiving switching wall, there will be no displacement gap between the control rod and the core receiving switching wall, thereby ensuring that the entire operating system is more stable and preventing the displacement latch, rotating member, sliding bead, or displacement member part located in the positioning groove from accidentally falling into the displacement gap of the control rod; the positioning groove is also provided with a sliding ramp to facilitate the sliding of the displacement member. Considering the relationship of the control groove, the displacement member may get stuck. By adding the sliding ramp, the stuckness caused during the fall can be solved; the control groove can also serve as a slide for the displacement latch, sliding bead, or displacement member part located in the positioning groove, facilitating the overall assembly.

[0055] As a further preferred embodiment of the present invention: the displacement member is further provided with a rotating abutment boss for abutting the adjusting rotating member and / or the positioning member is provided with an abutment boss for abutting the adjusting rotating member. The outer rod is provided with an internal abutment boss for abutting the adjusting rotating member; the rotating abutment boss, the abutment boss, and the internal abutment boss are all used to apply a certain pressure to the rotating member, thereby enabling the rotating member to counteract the negative interference caused by gravity; alternatively, by lengthening the displacement part, the displacement part can be placed between the displacement member and the bottom of the positioning groove, so that the rotating member can counteract the negative interference caused by gravity.

[0056] As a further preferred embodiment of the present invention: in order to facilitate the use of the fall-back auxiliary slope, the core-exiting boss is provided with a corresponding fall-back small slope; the slope area of ​​the fall-back small slope is small, so that the core-exiting boss will not be unable to effectively cooperate with the displacement component.

[0057] As a further preferred embodiment of the present invention: in order to facilitate better coordination with the core-exiting auxiliary slope, a corresponding small core-exiting slope is provided on the core-exiting boss; the slope area of ​​the small core-exiting slope is small and will not affect the coordination between the displacement component and the switching long wall.

[0058] As a further preferred embodiment of the present invention: the rotating boss is offset towards the core-gathering side. When a rotating component is used, the length of the rotating component becomes an issue. Due to the limitation of internal space, the length of the rotating component cannot be too long. Therefore, it is necessary to ensure that the position switching between the rotating component and the positioning groove can be performed normally even when the length of the rotating component is relatively short. However, the shorter the rotating component, the larger the rotation angle will be. As the rotation angle increases, some problems may occur with the sliding column adjusting the displacement of the inner groove. This is because when the rotating component contacts the switching long wall, the included angle between them must be greater than 90 degrees to facilitate the rotating component's passage through the switching long wall; otherwise, it may easily get stuck. When the rotating component contacts the core-gathering auxiliary wall, then... The angle between the two must be greater than 90 degrees to facilitate the rotation of the rotating part through the core-gathering auxiliary wall or the switching long wall; otherwise, it is easy to get stuck. When the rotating part is short, increasing the rotation angle will reduce the angle between the rotating part and the switching long wall, as well as the angle between the rotating part and the core-gathering auxiliary wall. However, by shifting the rotating boss as far as possible towards the core-gathering side, the angle between the rotating part and the switching long wall and the angle between the rotating part and the core-gathering auxiliary wall can be increased as much as possible without adjusting other parameters, thereby increasing the fault tolerance and improving the overall operation effect and stability.

[0059] When a trigger component is used, the auxiliary reset component is instead located between the control component and the trigger cover.

[0060] To adapt to different tool body sizes, thereby expanding the tool's application scenarios and compatibility, greatly increasing the tool's usage frequency, reducing resource reuse, making it more environmentally friendly, and improving product utilization; an adjustment hole is also provided at the structure that abuts against the tool body, and an adjustable base is provided inside the adjustment hole, with the adjustable base and the adjustment hole being engaged by threads or snaps; The structural part that is about to come into contact with the tool body is the part of the outer rod, adjusting part, or positioning part that is in contact with the tool body. The adjustable base changes the accommodating length of the tool body inside the outer rod or adjusting component by adjusting the positional relationship between the external adjusting tool and the adjusting hole. The external adjustment tool is also equipped with product-related scale lines or ordinary scale lines. The product-related scale lines refer to the fact that the external adjustment tool is specially designed for the tool body, and the handle is equipped with several commonly used length scale lines that are adapted to the tool body. By using these different scale lines, the tool can be rotated to be aligned with the bottom of the outer rod or adjustment part as needed, and the internal length will be adjusted to the internal length corresponding to that scale line. This allows consumers to adjust the tool directly according to their needs without having to remember the length parameters between different specifications.

[0061] In order to minimize the negative impact of gravity on the rotating parts, the adjusting part 4 is provided with a rotation stabilizing boss 45, and the rotation stabilizing boss 45 is also provided with a stabilizing abutment boss 451.

[0062] For ease of manufacturing, such as quick demolding of molds, the rotating stabilizing boss 45 can be disassembled into individual accessories and re-fixed to the adjusting part 4, outer rod 1 or positioning part 7 by means of installation. The installation method can be fastening with buckles, adhesive, magnets, screws or third-party tools.

[0063] When the press-to-extract and press-to-retract scheme is adopted, in order to prevent the pen lead from moving too far back and to ensure the stability of the overall shape, the aforementioned adjusting member 4 is also provided with an adjusting contact part 42.

[0064] In order to improve the overall stability of triggering the core retraction and ensure that the control component can remain in the limit state of being closest to the core exiting boss 713 in any non-triggering situation after each use, an auxiliary reset component 31 is provided between the control component 2 and the adjustment component 4.

[0065] As a further preferred embodiment of the present invention: the adjusting member is also provided with a side push part; the outer rod is provided with a side push groove to accommodate the sliding of the side push part; through the side push part, the adjusting member can be completely hidden inside the outer rod or partially exposed, so that the core can be released and retrieved at the same time by reverse lifting, and the adjusting member can be controlled to release and retrieve the core by the side push part.

[0066] As a further preferred embodiment of the present invention: the outer rod is further provided with a pressing groove; the pressing groove is further provided with a side pressing member, and the adjusting member is provided with a core-exit pressing auxiliary slope for use with the side pressing member; the side pressing member moves back and forth relative to the pressing groove, and when the side pressing member moves backward, it will squeeze the core-exit pressing auxiliary slope, thereby causing the adjusting member to move down and press the side pressing member to the bottom, which will cause the displacement member to move from the core-receiving point to the core-exiting point; the conversion ratio between the pressing stroke of the side pressing member and the downward movement of the adjusting member is affected by the slope of the core-exit pressing auxiliary slope. The smaller the slope of the core-exit pressing auxiliary slope, the higher the conversion ratio between the pressing stroke of the side pressing member and the downward movement of the adjusting member. The side pressing member moves a shorter distance, which can ensure that the adjusting member moves a greater distance, thereby meeting the minimum requirement of the core-exiting displacement of the adjusting member.

[0067] As a further preferred embodiment of the present invention: the side press member is provided with an inserting auxiliary latch protrusion, and the pressing groove is also provided with an inserting auxiliary groove that cooperates with the inserting auxiliary latch protrusion; when the side press member is pressed down to the bottom, causing the adjusting member to move down into place, so that after normal core ejection, because the position of the adjusting member has now achieved the core ejection fixed state through the reset member and the positioning member, the adjusting member will not apply a reset force to the side press member at this time. Therefore, the side press member will sway back and forth, which will affect the core ejection state. The writing process in this state causes unnecessary interference. Therefore, adding an auxiliary insert and an auxiliary groove can ensure that after the side press is pressed to the bottom, while the adjusting part controls the core output, the side press will be temporarily fixed to the outer rod. This temporary fixation is not reliable. When the automatic core retraction is triggered, the side press will be reset due to the force applied by the reset part to the adjusting part. Then the core output pressing auxiliary slope will cause the side press to disengage from the temporary fixation and reset, waiting for the next use.

[0068] When the side ejection or side pressing ejection method is used, the tail end of the tool body does not collide with the positioning component, but with the adjustment component, and the auxiliary reset component is also changed to be located between the control component and the positioning component.

[0069] The rotating component is also provided with a rotating auxiliary platform and / or a rotating mounting notch. The rotating auxiliary platform and the displacement component and / or the rotating abutment boss generate abutment. The rotating auxiliary platform can effectively help the rotating component counteract the interference of gravity. The rotating mounting notch can be used when the rotating boss is integrated between the rotating auxiliary platform and the displacement component, making it difficult to install the rotating component. In this case, the rotating component can be quickly, effectively and securely installed in place.

[0070] To ensure simpler and more convenient installation and facilitate automation, the aforementioned adjusting member is also provided with a movable opening; the movable opening is used to accommodate the positioning member. Although the positioning member itself does not move, the adjusting member will move up and down relative to the positioning member. In the case described in some embodiments, the positioning member needs to enter the adjusting member. Therefore, in certain situations, it is necessary to reserve a movable opening for the moving stroke of the adjusting member to accommodate the positioning member. To ensure that the outer rod and the adjusting component do not easily detach after assembly, the positioning component is also equipped with a positioning limiting platform. The positioning limiting platform can better abut against the tool body and can also limit the movement of the displacement component. Before assembly, the positioning limiting platform is inserted into the adjusting component from the side. After assembly, the adjusting component can only move up and down. Therefore, the positioning limiting component cannot detach from the adjusting component by moving up and down. Since the positioning component will cooperate with the outer rod, it can effectively prevent the adjusting component and the outer rod from separating.

[0071] As a further preferred embodiment of the present invention: the positioning groove is provided with an installation buffer groove; the installation buffer groove is mainly used in the actual installation process, when the displacement member 41 or other parts that replace the displacement member 41 and contact the positioning groove are made of plastic, and the insertion of the positioning member needs to be pushed in from bottom to top, because, considering that the displacement member 41 or other parts that replace the displacement member 41 and contact the positioning groove are made of plastic, this pushing process applies force to the adjusting member, and the adjusting member will apply force to the displacement member 41 or other parts that replace the displacement member 41 and contact the positioning groove, and the displacement member 41 will pass through the positioning groove, so that the positioning member and the outer rod or cover body apply force. This causes the positioning component to engage with the outer rod or cover. In this case, the requirements for the displacement component 41 are relatively high. Considering the stability of long-term use, it is best to avoid applying such strong force to the displacement component 41. Therefore, during installation, the optimal method is for the adjusting component to directly apply force to the positioning component, thereby causing the positioning component to engage with the outer rod or cover. However, this method requires high precision to ensure that the displacement component 41 can still move effectively within the positioning groove. By adding an installation buffer groove, the tolerance for this error can be improved, ensuring that during installation, the adjusting component applies force directly to the positioning component, rather than the displacement component 41 applying force to the positioning component. This prevents the displacement component 41 from being subjected to strong impacts, improving its service life and stability.

[0072] As a further preferred embodiment of the present invention: the positioning groove is provided with a core-gathering error groove; when the limiting of the core-gathering state does not need to be achieved by the restriction between the positioning groove and the displacement member 41 or other parts that are in contact with the positioning groove, the unnecessary contact between the displacement member 41 or other parts that are in contact with the positioning groove and the positioning groove should be avoided during core gathering, so as to better protect the displacement member 41 or other parts that are in contact with the positioning groove and the positioning groove.

[0073] As a further preferred embodiment of the present invention: the rotating component and / or the rotating abutment protrusion is further provided with a deformation groove. The deformation groove is mainly used to help the original part of the component to obtain a certain deformation capability, so as to better adapt to the engagement between the structures, and also to help the rotating component or displacement component overcome the interference of gravity.

[0074] A mechanical pen and its operating method include an outer rod, a reset component, a tool body, and an adjusting component. The outer rod is provided with a core ejector plate, an inner moving groove, and a positioning part; The adjusting component is provided with a displacement component, and the displacement component is also provided with a displacement locking protrusion. The displacement component moves between the core ejector plate and the inner moving groove.

[0075] As a preferred embodiment of the present invention, the adjusting member is prevented from detaching from the outer rod in the following two ways: The maximum movement distance of the displacement component is limited by the internal moving groove; The outer rod is also provided with a maximum limiting boss, and the adjusting member is also provided with a limiting ring platform. The maximum moving distance of the limiting ring platform is limited by the maximum limiting boss.

[0076] As a preferred embodiment of the present invention, the inner movable groove is implemented using two schemes: It does not penetrate the outer rod, but is located on the inner wall of the outer rod and directly connected to the core ejector plate; The outer rod and the underside of the core ejector plate have exposed through holes; When an exposed through hole is provided, in order to facilitate the entry of the displacement component into the core ejector stage, the displacement component is provided with an extension switching ramp and / or the exposed through hole is provided with an obstruction entry ramp.

[0077] As a preferred embodiment of the present invention: the outer rod triggering assembly.

[0078] As a further preferred embodiment of the present invention, the triggering component can be implemented in at least the following two ways: 1. The triggering assembly includes a trigger element, a trigger ring, and a rotating fastener; the trigger element passes through the rotating fastener and the trigger ring and is interconnected; the rotating fastener is fixed to the top of the outer rod; the trigger element has a rotating ring protrusion at its middle end and a trigger ring protrusion at its lower end; the trigger element can tilt and move downward relative to the rotating fastener 360 degrees through the rotating ring protrusion; the top of the control element has a downward moving ring protrusion; when the trigger ring protrusion moves towards the middle, it will squeeze the downward moving ring protrusion, indirectly causing the release auxiliary slope to move downward; the downward movement of the release auxiliary slope will cause the displacement element to disengage from the core ejector plate, and thus fall back into the inner moving slot under the influence of the reset element; 2. The outer rod is provided with a connecting body; the trigger assembly includes a limiting member, a trigger ring, and a trigger cover; the limiting member passes through the trigger cover and is connected to the connecting body, and the trigger cover passes through the connecting body and is connected to or abuts against the control member; when the trigger cover moves downward, the control member will also be pressed downward; the trigger ring is located between the limiting member and the trigger cover; a trigger auxiliary inclined ring is provided on the lower side of the limiting member, the upper side of the trigger ring, the lower side of the trigger ring, and / or the upper side of the trigger cover.

[0079] As a further preferred embodiment of the present invention: the outer rod is also provided with a non-switching ramp. By using the non-switching ramp, the core can be lifted and retracted. When core retraction is required, the adjusting member is moved further upward. By using the non-switching ramp, the displacement member is further deformed backward. When the deformation reaches a certain extent, it is released. The elastic force of the reset member makes the speed at which the displacement member falls back greater than the speed at which the displacement member recovers its deformation. Therefore, when the displacement member passes the core exiting platform, it will not be stuck back in the core exiting platform, but will fall back to the bottom, which is the core retraction limit.

[0080] As a further preferred embodiment of the present invention: a pressing rod is provided on the outer rod; a linkage channel is provided on the core ejector plate that passes through the outer rod, and the displacement component contacts the pressing rod through the linkage channel; the pressing rod is installed on the outer rod by means of a separate accessory or by integral molding.

[0081] As a further preferred embodiment of the present invention, the pressing rod can be installed in a fixed manner or in a flexible manner. If it is installed flexibly, the pressing rod can rotate relative to the outer rod.

[0082] As a further preferred embodiment of the present invention, the pressing rod is provided with a pressing protrusion.

[0083] As a further preferred embodiment of the present invention, the rear end of the displacement member is further provided with a displacement notch.

[0084] As a further preferred embodiment of the present invention, the push rod can also be used as a pen clip, and can realize the pen clip core retraction.

[0085] As a further preferred embodiment of the present invention: the cover can be removed from the outer rod to facilitate the installation of other components into the outer rod from top to bottom; after the cover is removed, the positioning part, the connecting body and the original outer rod structure without the switching ramp can be transferred to the cover depending on the actual application, so as to facilitate installation and use.

[0086] As a further preferred embodiment of the present invention: when the displacement component is not replaced by a sliding bead, a rotating component or a third-party accessory, the whole component is in the shape of a barb, which facilitates the engagement during core extraction.

[0087] Compared with existing technologies, the above technical solution has the following beneficial effects: 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.

[0088] 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.

[0089] Third, through structural integration and optimization of external components, better results can be achieved in reducing costs and assembly difficulty.

[0090] 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.

[0091] Fifth, it can transmit more external triggering force, thus achieving better triggering and core retraction.

[0092] VI. It greatly reduces costs and assembly difficulty.

[0093] VII. The triggering scheme for core retraction in this invention is more mature, and the actual triggering force required is several times less than that of Embodiment 5, resulting in more efficient triggering and a very good triggering effect. This is due to the innovative approach of this scheme, which uses the core-exiting protrusion to bear most of the elastic force of the reset component, while using a control component to restrict the adjustment component or displacement component from detaching from the core-exiting sliding wall. In this case, the control component is equivalent to a switch, bearing only a very small amount of pressure from the elastic force of the reset component. Simply pulling out the control component and releasing the return channel allows the displacement component to return to the core-retraction position through the core-exiting sliding wall and the reset component. Moreover, this scheme does not require consideration of the surface friction of the control component. Therefore, the smaller the surface friction of the control component, the smaller the triggering force required, and the more sensitive the triggering.

[0094] 8. The rotating boss adopts an eccentric design to further improve the utilization rate of internal space and ensure operational stability while further compressing the internal space.

[0095] 9. By adopting a rotating component and a rotating boss, the interference caused by gravity can be overcome. Therefore, the problem of rotation or translation of the displacement component can be perfectly solved. The integrity, durability and stability of the internal structure will be greatly improved, and the smoothness of the operation and the trigger sensitivity will also be greatly improved.

[0096] 10. The trigger ring has been modified with a trigger ramp to further improve the triggering effect; 11. Placing the positioning groove on the positioning component further reduces the difficulty of production and processing, and also reduces the difficulty of replacing parts. At the same time, it is also possible to produce flat positioning grooves. With current technology, flat surfaces are easier to produce than curved surfaces, and the accuracy and actual effect of flat surfaces are better than those of curved surfaces, which will further improve the smoothness and stability of operation.

[0097] 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.

[0098] Thirteen, improve product utilization and adaptability to various scenarios, save consumers' money and reduce the burden on the environment.

[0099] Fourteen, the triggering scheme of the present invention is more mature, and the actual triggering force required is several times less than that of embodiment 5, the triggering is more efficient and the triggering effect is very good. This is due to the fact that the present invention takes a different approach and chooses to use the core-exiting boss to bear most of the elastic force of the reset member, while using the control member to restrict the adjustment member or displacement member from leaving the core-exiting sliding wall. At this time, the control member is equivalent to a switch and only bears the pressure formed by the elastic force of the reset member. It is only necessary to pull out the control member and release the falling channel, so that the displacement member can return to the core-receiving position through the core-exiting sliding wall and the reset member. In the second trigger scheme, the friction between the displacement component and the core ejection stage is increased due to the force of the reset component. If the friction is reduced by decreasing the force of the reset component or by making the contact surfaces of the displacement component and the core ejection stage smoother, the core ejection state will become unstable. Therefore, the minimum trigger force of the second trigger scheme is limited, while the minimum trigger force of the first trigger scheme can be very, very low. This is why the trigger sensitivity of the second trigger scheme is not as good as that of the first trigger scheme.

[0100] 15. By adopting a scheme using movable grooves and sliding beads, the problem of rotation or translation of displacement components can be effectively solved. This greatly improves the integrity, durability, and stability of the internal structure, as well as the smoothness of the operation and the sensitivity of triggering. During sliding, there may be interference from gravity. However, this problem can be solved by increasing the friction between components, using a viscous liquid, adding a magnet to attract the sliding beads, using unidirectional limiting guidance to prevent the sliding beads from moving back, and / or using a multi-layered high-low staggered design to prevent the sliding beads from moving back.

[0101] Sixteen, by adopting a rotating component solution, the rotation and translation problems of the displacement component can be solved most stably. This greatly improves the integrity, durability, and stability of the internal structure, and also significantly enhances the smoothness of the operation and the trigger sensitivity. At the same time, it greatly improves the anti-interference ability against gravity interference, thus greatly improving the stability of operation. By applying pressure to the rotating component and / or increasing friction, excellent anti-interference ability against gravity interference can be achieved.

[0102] 17. More ejection methods: In addition to the existing trigger-and-retract mechanism, two new ejection systems, side-press and side-push, have been added to meet the needs of more users.

[0103] 18. When using the side-press and side-push lead-out method, the overall writing stability will be greatly improved. Attached Figure Description

[0150] The present invention will now be further described with reference to the accompanying drawings. Example 1

[0151] like Figures 1-7 The mechanical pen and its operating method are shown, including an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2, an adjustment component 4, and a positioning component 7.

[0152] The aforementioned positioning component 7 is installed inside the outer rod 1, and the aforementioned positioning component 7 is provided with a positioning groove 71; the aforementioned control component 2 is provided with a control rod 21.

[0153] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves movably within the positioning groove 71. The tail of the aforementioned tool body 5 abuts against the positioning member 7, the aforementioned tool body is placed within the adjusting member, and the aforementioned reset member is completely placed within the adjusting member.

[0154] The positioning groove 71 is provided with a core receiving switching wall 711, a switching elongated wall 71B, and a core exiting boss 713. The core exiting boss 713 is provided with a core exiting sliding wall 7131.

[0155] The bottom of the aforementioned core-gathering switching wall 711 is the core-gathering point A. At this time, the tool body 5 remains completely hidden inside the adjusting component 4, and this is the core-gathering state.

[0156] When the aforementioned displacement member 41 is located on the core ejection sliding wall 7131, it will move in the tilting direction of the core ejection sliding wall 7131 due to the influence of the core ejection sliding wall 7131 and the reset member 3. Before it completely detaches from the core ejection sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stop on the core ejection sliding wall 7131, and the position where the displacement member 41 stops at this time is the core ejection point B. This is the core ejection state.

[0157] The aforementioned control lever 21 enables an extended core-gathering method: the control lever 21 is equipped with a limiting boss 211 and a control switching wall 212. The limiting boss 211, instead of the control lever 21, restricts the displacement member 41. A core-gathering channel 214 is also provided between the limiting boss 211 and the control switching wall 212. During core gathering, the displacement member 41 moves upward, and through the core-gathering channel 214 and the core-gathering switching wall 211, the displacement member 41 is released from the restriction of the limiting boss 211, thus returning to the core-gathering point A.

[0158] The solution for the displacement member 41 to move left or right within the positioning groove 71 includes a rotating boss 412 on the displacement member 41, and a rotating member 82 on the rotating boss 412. One end of the rotating member 82 is sleeved on the rotating boss 412 and can rotate relative to the rotating boss 412. The other end of the rotating member 82 has a displacement part 821, which directly contacts the positioning groove 71 instead of the displacement member 41. Furthermore, the displacement member 41 does not need to rotate left or right; when left or right movement is required, the rotating member 82 rotates relative to the rotating boss 412.

[0159] The solution for the aforementioned displacement member 41 to move from the core receiving point A to the core exit point B within the positioning groove 71 includes a core exit guide wall 7132 on the side of the core receiving point A of the core exit boss 713. A core exit channel B2 is also provided between the aforementioned switching long wall 71B and the core exit boss 713. When the aforementioned displacement member 41 moves upward from the core receiving point A, it enters the core exit channel B2 under the influence of the core exit guide wall 7132, and then reaches above the core exit point B via the switching long wall 71B. At this point, releasing the external force will cause the displacement member 41 to fall back to the core exit point B.

[0160] To prevent human error, when the positioning groove 71 is equipped with a switching long wall 71B, a core-exit limiting wall 716 and a core-receiving auxiliary wall 717 can also be added. The core-exit limiting wall 716 is mainly used to limit the displacement member 41, preventing it from moving too far upwards and thus failing to stop at the core-exit point B. The core-receiving auxiliary wall 717 is used because the switching long wall 71B is blocked by the core-exit limiting wall 716, making it shorter and unable to continue to help the displacement member 41 to lift and retract the core. Therefore, the core-receiving auxiliary wall 717 can replace the original function of the switching long wall 71B and continue to help the displacement member 41 to retract the core by lifting.

[0161] To trigger the retraction of the core, the outer rod 1 is also equipped with a triggering component 6. This component 6 influences the movement of the control element 2, thereby changing the triggering form, direction, force, and range of the control element 2. The triggering component 6 includes a limiting member 61, a triggering ring 62, and a triggering cover 63. The limiting member 61 passes through the triggering cover 63 and is connected to the control element 2, which moves with the limiting member 61. The triggering cover 63 is connected to the outer rod 1. The triggering ring 62 is located between the limiting member 61 and the triggering cover 63. A triggering auxiliary oblique ring C is provided on the lower side of the limiting member 61, the upper side of the triggering ring 62, the lower side of the triggering ring 62, and / or the upper side of the triggering cover 63.

[0162] To enhance the overall stability of the triggering component and ensure stable and normal triggering even when the pen body is tilted, an auxiliary reset component 31 is provided between the aforementioned control component 2 and the outer rod 1.

[0163] To ensure easier triggering, the outer diameter of the trigger ring 62 is larger than that of the outer rod 1. A trigger ramp 621 is added to the lower end of the trigger ring 62. The lower the surface friction of the control rod and / or trigger ring, the better. The inclination angle of the trigger ramp is determined by a set trigger inclination angle. For example, if a 10° inclination is sufficient for triggering the core to retract, then the inclination angle of the ramp should be 10° or higher to improve the triggering effect.

[0164] To ensure that the control components can play a more stable control role, the aforementioned control component 2 and outer rod 1 can only move up and down, but cannot rotate left and right, and there is a maximum limit to downward movement.

[0165] To reduce unnecessary interference caused by production errors and further avoid unnecessary jamming, the aforementioned core receiving channel 214 is provided with a channel auxiliary slope 2141 on the B side near the core exit point.

[0166] To ensure stability during the descent, the aforementioned positioning groove 71 is also provided with an anti-detachment boss 719, and a descent channel 71A is also provided between the aforementioned limiting boss 211 and the anti-detachment boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211.

[0167] To ensure the control lever functions effectively, the positioning component 7 is also equipped with a control groove 715 to accommodate the vertical movement of the control lever 21. The control lever 21 passes through the control groove 715, thus preventing the displacement portion 821 of the rotating component 82 from detaching from the core-exit sliding wall 7131. Ideally, the control groove 715 and the control lever 21 should extend to the same horizontal line as the core-receiving point A. In this case, even if the control lever 21 moves upward due to the trigger component 6, when the displacement portion 821 releases the control lever 21 at the moment of triggering and enters the core-receiving switching wall 711, there will be no displacement gap between the control lever 21 and the core-receiving switching wall 711. This ensures greater stability of the entire operating system and prevents the displacement portion 821 from accidentally falling into the displacement gap of the control lever 21. The positioning groove 71 also includes a sliding ramp 718 to facilitate the sliding of the displacement component 41. Considering the relationship with the control groove 715, the displacement component 41 may experience jamming. Adding the sliding ramp 718 can solve the jamming problem during the descent. The aforementioned control groove 715 can also serve as a slide for loading the displacement part 821, facilitating overall assembly.

[0168] To enable the rotating component to counteract the negative interference caused by gravity, the displacement component 41 is further provided with a rotating abutment boss 413 for abutting and adjusting the rotating component 82, and / or the positioning component 7 is provided with an abutment boss for abutting and adjusting the rotating component 82. The outer rod 1 is provided with an internal abutment boss for abutting and adjusting the rotating component 82. The rotating abutment boss 413, the abutment boss, and the internal abutment boss are all used to apply a certain pressure to the rotating component 82, thereby enabling the rotating component 82 to counteract the negative interference caused by gravity. Alternatively, the length of the displacement part 821 can be increased so that the displacement part 821 abuts against the bottom of the displacement component 41 and the positioning groove 71; this mainly utilizes the deformation capability of the displacement component 41 and / or the rotating component 82 itself, and by applying pressure to the displacement component 41 and / or the rotating component 82, the friction and pressure between the rotating component 82 and the structure in contact with it are increased, thereby counteracting the negative interference caused by gravity.

[0169] To utilize the internal space more efficiently and improve space utilization while ensuring optimal stability, the aforementioned rotating boss 412 is offset towards the A side of the core-gathering point. When using the rotating component 82, the length of the rotating component 82 becomes an issue. Due to the limitations of the internal space, the length of the rotating component 82 cannot be too long. Therefore, it is necessary to ensure that even when the length of the rotating component 82 is relatively short, the position switching between the rotating component 82 and the positioning groove 71 can still be performed normally. The shorter the rotating component, the greater the rotation angle will be. As the rotation angle increases, the sliding column may experience some problems in adjusting the displacement of the inner groove, such as jamming and getting stuck. This is because when the rotating component contacts the switching long wall, the included angle between the two must be greater than 90 degrees to facilitate the rotating component's passage through the switching long wall; otherwise, it is easy to get stuck. Similarly, when the rotating component contacts the core-gathering auxiliary wall, the included angle between the two must also be greater than 90 degrees to facilitate the rotating component's passage through the core-gathering auxiliary wall or the switching long wall; otherwise, it is easy to get stuck. When the rotating component is shorter, increasing the rotation angle will reduce the angles between the rotating component and the switching long wall, as well as the angle between the rotating component and the core-collecting auxiliary wall. This is based on the assumption that the angles between the switching long wall, the core-collecting auxiliary wall, and the horizontal line remain unchanged. However, by shifting the rotating boss as far as possible towards the core-collecting side, the angles between the rotating component and the switching long wall, and between the rotating component and the core-collecting auxiliary wall, can be increased as much as possible without adjusting other parameters. This increases the fault tolerance and improves the overall operational efficiency and stability.

[0170] To further improve the fault tolerance rate: the lower end of the control switching wall 212 is higher than the upper end of the core receiving auxiliary wall 717, which can achieve better results.

[0171] To facilitate the main auxiliary reset component, the aforementioned control component 2 is also equipped with a reset ring platform 24.

[0172] To further improve the fault tolerance rate of the displacement component 41 falling back, the aforementioned limiting boss 211 is also provided with a limiting fall slope 2111.

[0173] To ensure simpler and more convenient installation and facilitate automation, the aforementioned adjusting member 4 is also provided with a movable opening 43; the movable opening 43 is also provided with a clamping extension 431, which is adapted to the positioning member 7. After the positioning member 7 is engaged with the clamping extension 431, it can slide up and down relative to the adjusting member 4. Even when the outer rod 1 is not installed, it is not easy to disengage from the adjustment member 4; the movable opening 43 is used to accommodate the positioning member 7. Although the positioning member 7 itself does not move, the adjusting member 4 will move up and down relative to the positioning member 7. In the case described in some embodiments, the positioning member 7 needs to enter the adjusting member 4. Therefore, in certain cases, it is necessary to reserve the movable opening 43 for the moving stroke of the adjusting member 4 for the positioning member 7. To ensure that the outer rod and the adjusting component do not easily detach after assembly, the positioning component 7 is also provided with a positioning limit platform 7B. The positioning limit platform 7B can better abut against the tool body 5, and at the same time, it can also form a limit with the displacement component 41. Before assembly, the positioning limit platform 7B is inserted into the adjusting component 4 from the side. After assembly, the adjusting component 4 can only move up and down. Therefore, the positioning limit platform 7B cannot detach from the adjusting component 4 by moving up and down. The positioning component 7 will cooperate with the outer rod, which can effectively prevent the adjusting component 4 and the outer rod 1 from separating.

[0174] To better secure the rotating component 82, the displacement component 41 is further provided with a rotating fastener 4121 for abutting the rotating component 82. The rotating fastener 4121 is divided into a clamping part 4131 and a snap-fit ​​part 4132. The rotating fastener 4121 snaps into the side of the displacement component 41 in a snap-fit ​​manner through the snap-fit ​​part 4132. The displacement component 41 is also provided with a corresponding clamping groove 41Y. After the snap-fit ​​part 4132 snaps into the clamping groove 41Y, the clamping part 4131 continuously applies a clamping force to the rotating component 82, thereby giving the rotating component 82 a certain damping effect when rotating left and right, thus overcoming the interference of gravity.

[0175] Installation method: 1. First, assemble the positioning component, rotating component, and adjusting component into an adjusting assembly. One end of the rotating component is fitted onto the rotating boss located on the adjusting component. Insert the positioning component into the adjusting component, and then insert the displacement part of the other end into the positioning groove. At this point, the adjusting assembly is complete. 2. Then, install the adjustment component into the outer rod from top to bottom. The adjustment component will not be able to move down too much due to the limit between the positioning part and the outer rod. After the positioning part stops in the installation position, install the control part, auxiliary reset part and trigger cover into the outer rod from top to bottom in sequence. 3. Next, place the trigger ring on the trigger cover, pass the limiting component through the trigger ring and the trigger cover, and assemble it with the control component; then the assembly of the pen is roughly complete. 4. Finally, insert the tool body, reset piece, and pen changer into the adjustment unit from bottom to top, and then install the pen changer and adjustment piece into place.

[0176] Core extraction method: The third method of core extraction is adopted: the external force control adjustment component 4 moves upward. When the above displacement component 41 moves from the core receiving point A, it enters the core extraction channel B2 under the influence of the core extraction guide wall 7132. Then, by switching the long wall 71B, it reaches the top of the core extraction point B. At this time, the external force is released, and the displacement component 41 will fall back to the core extraction point B.

[0177] It has both of the following core-collecting methods: 1. Triggering the retraction scheme one: 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 limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement part 821 loses the restriction of the control member 2 and will slide down along the lead-out sliding wall 7131 to the retraction point A. At this time, the main body of the tool will be completely hidden in the pen changing part D. 2. Lifting and core-gathering scheme one: The external force control adjustment component 4 moves upward, and through the core-gathering auxiliary wall 717 on the positioning groove 71 and the control switching wall 212 on the control component 2, the displacement component 41 bypasses the limitation of the limiting boss 211 and falls back to the core-gathering point A under the influence of the reset component 3. Example 2

[0178] like Figures 8-13 The mechanical pen and its operating method are shown, including an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2 and an adjustment component 4.

[0179] The aforementioned control component 2 is provided with a control rod 21; the aforementioned outer rod 1 is provided with a positioning groove 71.

[0180] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves movably within the positioning groove 71.

[0181] When the lead-out and lead-retracting scheme is adopted, in order to prevent the lead from moving too far back and to ensure the stability of the overall shape, the aforementioned adjusting member 4 is also provided with an adjusting abutment part 42. The tail of the aforementioned tool body 5 abuts against the adjusting abutment part 42, and the aforementioned tool body 5 and the reset member are completely placed inside the outer rod.

[0182] In order to improve the overall stability of triggering the core retraction and ensure that the control component can remain in the limit state of being closest to the core exiting boss 713 in any non-triggering situation after each use, an auxiliary reset component 31 is provided between the control component 2 and the adjustment component 4.

[0183] The positioning groove 71 is provided with a core receiving switching wall 711, a switching elongated wall 71B, and a core exiting boss 713. The core exiting boss 713 is provided with a core exiting sliding wall 7131.

[0184] The bottom of the aforementioned core-gathering switching wall 711 is the core-gathering point A. At this time, the tool body 5 remains completely hidden inside the adjusting component 4, and this is the core-gathering state.

[0185] When the aforementioned displacement member 41 is located on the core ejection sliding wall 7131, it will move in the tilting direction of the core ejection sliding wall 7131 due to the influence of the core ejection sliding wall 7131 and the reset member 3. Before it completely detaches from the core ejection sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stop on the core ejection sliding wall 7131, and the position where the displacement member 41 stops at this time is the core ejection point B. This is the core ejection state.

[0186] The aforementioned control lever 21 realizes an extended core-retrieving method: the aforementioned control lever 21 is provided with a fall-back auxiliary slope 213. When retrieving the core, the aforementioned displacement member 41 moves upward and leaves the space above the core-exiting boss 713 by switching the long wall 71B. Subsequently, it jumps over the restriction of the control lever 21 by the reset member 3 and the fall-back auxiliary slope 213.

[0187] The solution for the displacement member 41 to move left or right within the positioning groove 71 includes a displacement locking protrusion 411 on the displacement member 41. The displacement locking protrusion 411 directly contacts the positioning groove 71 instead of the displacement member 41. Furthermore, the displacement member 41 possesses a certain lateral deformation and bending capability, allowing it to bend to a certain extent, thus satisfying the requirement that the displacement member 41 will move left or right while moving within the positioning groove 71, provided that the adjusting member 4 itself remains stationary.

[0188] The solution for moving the aforementioned displacement member 41 from the core receiving point A to the core exit point B within the positioning groove 71 is provided with a core exiting boss 713 near the core receiving point A and / or a core exiting member 41 near the core exit point B. The aforementioned displacement member 41 has the ability to deform and bend forward and backward. When the displacement member 41 passes the core exiting boss 713, it can cross the core exiting boss 713 and reach the core exit point B through the core exiting auxiliary slope B1 and the deformation and bending ability of the displacement member 41.

[0189] To achieve triggering of the core retraction, the outer rod 1 is also equipped with a triggering component 6. The triggering component 6 influences the movement of the control element 2, thereby changing the triggering form, triggering direction, triggering force, and triggering range of the control element 2. The outer rod 1 is equipped with a connecting body 11. The triggering component 6 includes a limiting member 61, a triggering ring 62, and a triggering cover 63. The limiting member 61 passes through the triggering cover 63 and is connected to the connecting body 11. The triggering cover 63 passes through the connecting body 11 and is connected to or abuts against the control element 2. When the triggering cover 63 moves downward, the control element 2 is also pressed downward. The triggering ring 62 is located between the limiting member 61 and the triggering cover 63. A triggering auxiliary inclined ring C is provided on the lower side of the limiting member 61, the upper side of the triggering ring 62, the lower side of the triggering ring 62, and / or the upper side of the triggering cover 63.

[0190] To enhance the overall stability of the triggering component and ensure stable and normal triggering even when the pen body is tilted, an auxiliary reset component 31 is provided between the aforementioned control component 2 and the outer rod 1.

[0191] To ensure easier triggering, the outer diameter of the trigger ring 62 is larger than the outer diameter of the outer rod 1. The lower the surface friction of the control rod and / or trigger ring, the better.

[0192] To ensure that the control components can play a more stable control role, the aforementioned control component 2 and outer rod 1 can only move up and down, but cannot rotate left and right, and there is a maximum limit to the upward movement.

[0193] Switching from core-receiving state to core-exiting state: With external force, while keeping the outer rod 1 stationary, move the adjusting member 4 to move the displacement member 41 from the core-receiving point A to below the core-exiting boss 713. Then release the external force, and the displacement member 41 falls back under the influence of the reset member 3. After contacting the core-exiting sliding wall 7131 and the control rod 21, it stops at the core-exiting point B.

[0194] For better pressing, a pressing element 43 is also provided, which cooperates with the adjusting element.

[0195] To facilitate the main auxiliary reset component, the aforementioned control component 2 is also equipped with a reset ring platform 24.

[0196] To adapt to different tool body sizes, thereby expanding the tool's application scenarios and compatibility, significantly increasing its usage frequency, reducing resource reuse, and making it more environmentally friendly and improving product utilization, an adjustment hole E1 is provided at the structure that abuts against the tool body 5. An adjustable base E is also provided within the adjustment hole E1, and the adjustable base E and the adjustment hole E1 are connected by threads or snap-fit. The structure that abuts against the tool body 5 is the part of the outer rod 1, the adjusting component 4, or the positioning component 7 that contacts the tool body 5. The adjustable base E adjusts the positional relationship between the tool and the adjustment hole E1 externally, thereby... The external adjustment tool can be adjusted to accommodate different lengths of the tool body 5 within the outer rod 1 or adjusting component 4. The external adjustment tool also features product-related or standard scale lines. These product-related scale lines indicate that the external adjustment tool is specifically designed for the tool body 5. The handle has scale lines of several commonly used lengths to fit the tool body 5. By rotating the tool to align with the bottom of the outer rod 1 or adjusting component 4 according to requirements, the internal length is adjusted to the corresponding internal length of that scale line. This allows consumers to adjust the tool directly according to their needs without needing to memorize the length parameters between different specifications.

[0197] Installation method: 1. First, install the trigger cover, trigger ring, and limiting component into the outer rod in sequence from top to bottom. The limiting component passes through the trigger ring, trigger cover, and connecting body to cooperate. 2. Insert the positioning component, auxiliary reset component, adjustment component, pen refill, reset component, and pen replacement part into the outer rod in sequence from bottom to top, and mate the pen replacement part with the outer rod; 3. Finally, assemble the pressing and adjusting parts.

[0198] The core ejection method adopts the second pressing core ejection scheme: keep the outer rod 1 still, and the external force controls the adjustment component 4 to move down. When the displacement component 41 passes the core ejection boss 713, it passes the core ejection auxiliary slope B1 and the deformation and bending ability of the displacement component 41, and reaches the core ejection point B.

[0199] It has both of the following core-collecting methods: 1. Triggering the retraction scheme one: 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 cover 63, and the trigger cover 63 will move down, thereby driving the control member 2 to move down. When the control member 2 moves down, the displacement boss 411 loses the restriction of the control member 2 and will slide down along the lead-out sliding wall 7131 to the retraction point A. At this time, the main body of the tool will be completely hidden in the pen changing part D. 2. Pressing and retracting scheme two: The external force control adjustment component 4 moves down and reaches below the limiting boss 211 by switching the long wall 71B. The external force is released and the return auxiliary slope 213 on the control rod 21 and the reset component 3 are used to make the displacement component 41 cross the limit of the control component 2 and return to the retracting point A. Example 3

[0200] like Figures 14-18 The mechanical pen and its operating method are shown, including an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2 and an adjustment component 4.

[0201] The outer rod 1 is provided with a positioning groove 71 and a positioning part 72. The adjusting member 4 is provided with a displacement member 41, which moves movably within the positioning groove 71.

[0202] The aforementioned control component 2 is equipped with a control lever 21. The tail of the aforementioned tool body 5 abuts against the positioning part 72, the aforementioned tool body 5 is partially placed within the adjusting component 4, and the aforementioned reset component 3 is completely placed within the adjusting component 4. The positioning groove 71 is provided with a core receiving switching wall 711, a switching elongated wall 71B, and a core exiting boss 713. The core exiting boss 713 is provided with a core exiting sliding wall 7131.

[0203] The bottom of the aforementioned core-gathering switching wall 711 is the core-gathering point A. At this time, the tool body 5 remains completely hidden inside the adjusting component 4, and this is the core-gathering state.

[0204] When the aforementioned displacement member 41 is located on the core ejection sliding wall 7131, it will move in the tilting direction of the core ejection sliding wall 7131 due to the influence of the core ejection sliding wall 7131 and the reset member 3. Before it completely detaches from the core ejection sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stop on the core ejection sliding wall 7131, and the position where the displacement member 41 stops at this time is the core ejection point B. This is the core ejection state.

[0205] The aforementioned control lever 21 realizes an extended core-retrieving method: the aforementioned control lever 21 is provided with a fall-back auxiliary slope 213. When retrieving the core, the aforementioned displacement member 41 moves upward and leaves the space above the core-exiting boss 713 by switching the long wall 71B. Subsequently, it jumps over the restriction of the control lever 21 by the reset member 3 and the fall-back auxiliary slope 213.

[0206] The solution for the displacement member 41 to move left or right within the positioning groove 71 includes a displacement locking protrusion 411 on the displacement member 41. The displacement locking protrusion 411 directly contacts the positioning groove 71 instead of the displacement member 41. Furthermore, the displacement member 41 possesses a certain lateral deformation and bending capability, allowing it to bend to a certain extent, thus satisfying the requirement that the displacement member 41 will move left or right while moving within the positioning groove 71, provided that the adjusting member 4 itself remains stationary.

[0207] The solution for moving the aforementioned displacement member 41 from the core receiving point A to the core exit point B within the positioning groove 71 is provided with a core exiting boss 713 near the core receiving point A and / or a core exiting member 41 near the core exit point B. The aforementioned displacement member 41 has the ability to deform and bend forward and backward. When the displacement member 41 passes the core exiting boss 713, it can cross the core exiting boss 713 and reach the core exit point B through the core exiting auxiliary slope B1 and the deformation and bending ability of the displacement member 41.

[0208] To trigger the retraction of the core, the outer rod 1 is also equipped with a triggering component 6. This component 6 influences the movement of the control element 2, thereby changing the triggering form, direction, force, and range of the control element 2. The triggering component 6 includes a limiting member 61, a triggering ring 62, and a triggering cover 63. The limiting member 61 passes through the triggering cover 63 and is connected to the control element 2, which moves with the limiting member 61. The triggering cover 63 is connected to the outer rod 1. The triggering ring 62 is located between the limiting member 61 and the triggering cover 63. A triggering auxiliary oblique ring C is provided on the lower side of the limiting member 61, the upper side of the triggering ring 62, the lower side of the triggering ring 62, and / or the upper side of the triggering cover 63.

[0209] To ensure easier triggering, the outer diameter of the trigger ring 62 is larger than the outer diameter of the outer rod 1. The lower the surface friction of the control rod and / or trigger ring, the better.

[0210] To ensure that the control components can play a more stable control role, the aforementioned control component 2 and outer rod 1 can only move up and down, but cannot rotate left and right, and there is a maximum limit to downward movement.

[0211] Switching from core-receiving state to core-exiting state: With external force, while keeping the outer rod 1 stationary, move the adjusting member 4 to move the displacement member 41 from the core-receiving point A to above the core-exiting boss 713. Then release the external force, and the displacement member 41 falls back under the influence of the reset member 3. After contacting the core-exiting sliding wall 7131 and the control rod 21, it stops at the core-exiting point B.

[0212] To better prevent the adjusting component 4 from detaching from the outer rod, the displacement boss 411 can be separated out. After the adjusting component is installed into the outer rod, the adjusting component 4 can be installed separately; then the adjusting component 4 will not easily detach from the outer rod.

[0213] To adapt to different tool body sizes, thereby expanding the tool's application scenarios and compatibility, significantly increasing its usage frequency, reducing resource reuse, and making it more environmentally friendly and improving product utilization, an adjustment hole E1 is provided at the structure that abuts against the tool body 5. An adjustable base E is also provided within the adjustment hole E1, and the adjustable base E and the adjustment hole E1 are connected by threads or snap-fit. The structure that abuts against the tool body 5 is the part of the outer rod 1, the adjusting component 4, or the positioning component 7 that contacts the tool body 5. The adjustable base E adjusts the positional relationship between the tool and the adjustment hole E1 externally, thereby... The external adjustment tool can be adjusted to accommodate different lengths of the tool body 5 within the outer rod 1 or adjusting component 4. The external adjustment tool also features product-related or standard scale lines. These product-related scale lines indicate that the external adjustment tool is specifically designed for the tool body 5. The handle has scale lines of several commonly used lengths to fit the tool body 5. By rotating the tool to align with the bottom of the outer rod 1 or adjusting component 4 according to requirements, the internal length is adjusted to the corresponding internal length of that scale line. This allows consumers to adjust the tool directly according to their needs without needing to memorize the length parameters between different specifications.

[0214] In order to enable the adjustment component to rotate better and thus facilitate the switching of position states, the adjustment component 4 is also provided with a pen changing part D. There are also two magnetic attraction objects H between the adjustment component 4 and the pen changing part D. The magnetic attraction between the two magnetic attraction objects H enables the adjustment component 4 and the pen changing part D to cooperate, and at the same time, it can also ensure that the adjustment component 4 can rotate relative to the pen changing part D.

[0215] Installation method: 1. Insert the control component, trigger cover, trigger ring, and limit component into the outer rod in sequence from top to bottom. The trigger cover and the outer rod should cooperate. The limit component should pass through the trigger ring, trigger cover, and control component to cooperate. 2. Insert the adjustable base E into the outer rod using the external adjustment tool, and adjust it into place according to the actual required size of the tool body; 3. Then, install the adjusting part, tool body, reset part and pen changing part into the outer rod in sequence from bottom to top, and make the pen changing part and adjusting part fit together; 4. At this point, check whether the displacement boss 411 is located in the positioning groove 71. If not, adjust the position of the adjusting component to ensure that the displacement boss 411 is placed in the positioning groove 71.

[0216] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the pen should be held upright before the lead can be ejected to ensure a high success rate. Alternatively, an auxiliary reset component can be added directly between the control component and the trigger cover to improve the user experience.

[0217] Core ejection method: adopt the second core ejection scheme: keep the outer rod 1 still, and use external force to control the adjustment component 4 to move upward. When the displacement component 41 passes the core ejection boss 713, it passes the core ejection auxiliary slope B1 and the deformation and bending ability of the displacement component 41, and reaches the core ejection point B. It has both of the following core-collecting methods: 1. Triggering the retraction scheme one: 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 limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement boss 411 loses the restriction of the control member 2 and will slide down along the lead-out sliding wall 7131 to the retraction point A. At this time, the main body of the tool will be completely hidden in the pen changing part D. 2. Lifting and core-gathering scheme two: The external force control adjustment component 4 moves upward, and reaches the upper part of the limit boss 211 by switching the long wall 71B. The external force is released and the return auxiliary slope 213 on the control rod 21 and the reset component 3 are used to make the displacement component 41 cross the limit of the control component 2 and return to the core-gathering point A. Example 4

[0218] like Figures 19-23The mechanical pen and its operating method are shown. The positional relationship of the tool body is determined by the displacement of an adjusting member configured in the outer rod. The tool body has two positional states: core retraction and core extension. The adjusting member achieves relative stability between these two positional states through a positioning member or a positioning groove, a reset member, and a control member on the outer rod. The reset member continuously provides a force to the adjusting member through the tool body transmission, so that the state of the displacement member on the adjusting member when it is in the core retraction position is relatively stable. When the displacement member moves to the core extension position in the positioning groove, the control member restricts the displacement member to make the core extension position relatively stable. The above-mentioned switching from the core output state to the core recovery state can be achieved in three ways: 1. Movement control for core retraction: By influencing the upward or downward movement of the control component through external force, the displacement component is freed from the constraint of the control component. Then, the displacement component will be affected by the reset component and move downward, thereby realizing core retraction. 2. Lifting and retracting the core: Keep the outer rod stationary, and use external force to control the adjustment component to move upward. Through the switching wall on the positioning groove, the control switching wall on the control component, and the reset component, the displacement component bypasses the restriction of the control component and returns to the core retracting position. 3. Lifting and core-gathering scheme 2: Keep the outer rod stationary, and move the external force control adjustment component upward. Through the switching long wall and reset component on the positioning groove, the displacement component passes the restriction of the control component and returns to the core-gathering position.

[0219] The solution for the displacement member 41 to move left or right within the positioning groove 71 includes a rotating boss 412 on the displacement member 41, and a rotating member 82 on the rotating boss 412. One end of the rotating member 82 is sleeved on the rotating boss 412 and can rotate relative to the rotating boss 412. The other end of the rotating member 82 has a displacement part 821, which directly contacts the positioning groove 71 instead of the displacement member 41. Furthermore, the displacement member 41 does not need to rotate left or right; when left or right movement is required, the rotating member 82 rotates relative to the rotating boss 412.

[0220] The solution for the aforementioned displacement member 41 to move from the core receiving point A to the core exit point B within the positioning groove 71 includes a core exit guide wall 7132 on the side of the core receiving point A of the core exit boss 713. A core exit channel B2 is also provided between the aforementioned switching long wall 71B and the core exit boss 713. When the aforementioned displacement member 41 moves upward from the core receiving point A, it enters the core exit channel B2 under the influence of the core exit guide wall 7132, and then reaches above the core exit point B via the switching long wall 71B. At this point, releasing the external force will cause the displacement member 41 to fall back to the core exit point B.

[0221] To prevent human error, the positioning groove 71 is also equipped with a core-exit limiting wall 716 and a core-receiving auxiliary wall 717. The core-exit limiting wall 716 is mainly used to limit the displacement member 41, preventing it from moving too far upwards and thus failing to stop at the core-exit point B. The core-receiving auxiliary wall 717 is used because after the switching long wall 71B is blocked by the core-exit limiting wall 716, its length becomes shorter and it can no longer help the displacement member 41 to lift and retract the core. Therefore, the core-receiving auxiliary wall 717 can replace the original function of the switching long wall 71B and continue to help the displacement member 41 to retract the core by lifting.

[0222] To ensure that the control components can play a more stable control role, the aforementioned control component 2 and outer rod 1 can only move up and down, but cannot rotate left and right, and there is a maximum limit to downward movement.

[0223] To reduce unnecessary interference caused by production errors and further avoid unnecessary jamming, the aforementioned core receiving channel 214 is provided with a channel auxiliary slope 2141 on the B side near the core exit point.

[0224] To ensure stability during the descent, the aforementioned positioning groove 71 is also provided with an anti-detachment boss 719, and a descent channel 71A is also provided between the aforementioned limiting boss 211 and the anti-detachment boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211.

[0225] To ensure the control lever functions effectively, the positioning component 7 is also equipped with a control groove 715 to accommodate the vertical movement of the control lever 21. The control lever 21 passes through the control groove 715, thus preventing the displacement portion 821 of the rotating component 82 from detaching from the core-exit sliding wall 7131. Ideally, the control groove 715 and the control lever 21 should extend to the same horizontal line as the core-receiving point A. In this case, even if the control lever 21 moves upward due to the trigger component 6, when the displacement portion 821 releases the control lever 21 at the moment of triggering and enters the core-receiving switching wall 711, there will be no displacement gap between the control lever 21 and the core-receiving switching wall 711. This ensures greater stability of the entire operating system and prevents the displacement portion 821 from accidentally falling into the displacement gap of the control lever 21. The positioning groove 71 also includes a sliding ramp 718 to facilitate the sliding of the displacement component 41. Considering the relationship with the control groove 715, the displacement component 41 may experience jamming. Adding the sliding ramp 718 can solve the jamming problem during the descent. The aforementioned control groove 715 can also serve as a slide for loading the displacement part 821, facilitating overall assembly.

[0226] To enable the rotating component to counteract the negative interference caused by gravity, the displacement component 41 is further provided with a rotating abutment boss 413 for abutting and adjusting the rotating component 82, and / or the positioning component 7 is provided with an abutment boss for abutting and adjusting the rotating component 82. The outer rod 1 is provided with an internal abutment boss for abutting and adjusting the rotating component 82. The rotating abutment boss 413, the abutment boss, and the internal abutment boss are all used to apply a certain pressure to the rotating component 82, thereby enabling the rotating component 82 to counteract the negative interference caused by gravity. Alternatively, the length of the displacement part 821 can be increased so that the displacement part 821 abuts against the bottom of the displacement component 41 and the positioning groove 71.

[0227] To utilize the internal space more efficiently and improve space utilization while ensuring optimal stability, the aforementioned rotating boss 412 is offset towards the A side of the core-gathering point. When using the rotating component 82, the length of the rotating component 82 becomes an issue. Due to the limitations of the internal space, the length of the rotating component 82 cannot be too long. Therefore, it is necessary to ensure that even when the length of the rotating component 82 is relatively short, the position switching between the rotating component 82 and the positioning groove 71 can still be performed normally. The shorter the rotating component, the greater the rotation angle will be. As the rotation angle increases, the sliding column may experience some problems in adjusting the displacement of the inner groove, such as jamming and getting stuck. This is because when the rotating component contacts the switching long wall, the included angle between the two must be greater than 90 degrees to facilitate the rotating component's passage through the switching long wall; otherwise, it is easy to get stuck. Similarly, when the rotating component contacts the core-gathering auxiliary wall, the included angle between the two must also be greater than 90 degrees to facilitate the rotating component's passage through the core-gathering auxiliary wall or the switching long wall; otherwise, it is easy to get stuck. When the rotating component is shorter, increasing the rotation angle will reduce the angles between the rotating component and the switching long wall, as well as the angle between the rotating component and the core-collecting auxiliary wall. This is based on the assumption that the angles between the switching long wall, the core-collecting auxiliary wall, and the horizontal line remain unchanged. However, by shifting the rotating boss as far as possible towards the core-collecting side, the angles between the rotating component and the switching long wall, and between the rotating component and the core-collecting auxiliary wall, can be increased as much as possible without adjusting other parameters. This increases the fault tolerance and improves the overall operational efficiency and stability.

[0228] Switching from core-receiving state to core-exiting state: With external force, while keeping the outer rod 1 stationary, move the adjusting member 4 to move the displacement member 41 from the core-receiving point A to above the core-exiting boss 713. Then release the external force, and the displacement member 41 falls back under the influence of the reset member 3. After contacting the core-exiting sliding wall 7131 and the control rod 21, it stops at the core-exiting point B.

[0229] To further improve the fault tolerance rate: the lower end of the control switching wall 212 is higher than the upper end of the core receiving auxiliary wall 717, which can achieve better results.

[0230] To facilitate installation and maintenance, the outer rod is also provided with a cover 14, which cooperates with the outer rod.

[0231] To facilitate the insertion of the adjustment component into the outer rod from bottom to top, the positioning member 7 needs to cooperate with the cover 14. In this embodiment, a snap-fit ​​method is used, so the positioning member 7 is also provided with a snap-fit ​​part 74; while the cover 14 is provided with a cover buckle 141; and the cover buckle 141 is distributed in segments and is curved inward to facilitate the insertion of the snap-fit ​​part 74 into the cover 14; after the snap-fit ​​part 74 is inserted into the cover 14, it is not easy to pull it out.

[0232] To facilitate the main auxiliary reset component, the aforementioned control component 2 is also equipped with a reset ring platform 24.

[0233] In order to minimize the negative impact of gravity on the rotating parts, the aforementioned adjusting part 4 is provided with a rotation stabilizing boss 45, and the aforementioned rotation stabilizing boss 45 is also provided with a stabilizing abutment boss 451.

[0234] For ease of manufacturing, such as quick demolding of molds, the aforementioned rotating stabilizing boss 45 can be disassembled into individual accessories and re-fixed to the adjusting part 4, outer rod 1 or positioning part 7 by means of installation. The installation method can be fastening with clips, adhesive, magnets, screws or third-party tools.

[0235] To avoid unnecessary impact on the rotating part 82 during installation, the positioning groove 71 is provided with an installation buffer groove 7D. To better protect the rotating component 82 and the positioning groove, the positioning component 7 is also provided with a positioning limiting platform 7B, and the positioning groove 71 is provided with a core-gathering error groove 7F. When the limiting between the positioning limiting platform 7B and the displacement component 41 is achieved, it is not necessary to achieve the limitation between the rotating component 82 and the positioning groove. In this case, unnecessary contact between the rotating component 82 and the positioning groove should be avoided when the core is being gathered. The core-gathering error groove 7F can provide a larger error size to ensure that the rotating component 82 and the positioning groove will not be impacted when the core is being gathered.

[0236] Installation method: First, assemble the positioning component, rotating component, and adjusting component into an adjusting assembly. One end of the rotating component is fitted onto the rotating boss located on the adjusting component. Then, insert the positioning component into a portion of the adjusting component, and finally, insert the displacement portion at the other end into the positioning groove. The adjustment components are now complete; Insert the cover 14 into the outer rod from top to bottom, so that the cover and the outer rod fit together. Then, the auxiliary reset component, control component, and adjustment component are installed into the outer rod from bottom to top; the clips on the positioning component and the cover are then engaged in place. Finally, insert the tool body, reset piece, and pen changer into the adjustment unit from bottom to top, and then install the pen changer and adjustment piece into place.

[0237] The cover 14 mentioned above can also be installed last.

[0238] The core ejection method adopts the third lifting core ejection scheme: the external force control adjustment component 4 moves upward. When the above displacement component 41 moves from the core receiving point A, it is affected by the core ejection guide wall 7132 and enters the core ejection channel B2. Then, by switching the long wall 71B, it reaches above the core ejection point B. At this time, the external force is released, and the displacement component 41 will fall back to the core ejection point B.

[0239] It simultaneously supports the following three core-collecting methods: 1. Movement control for core retraction: By using external force to move the control component 2 upward, the displacement component 41 is freed from the restriction of the control component 2. Then, the displacement component 41 will move under the influence of the reset component 3, thereby realizing core retraction. 2. Lifting and core-gathering scheme one: The external force control adjustment component 4 moves upward, and through the core-gathering auxiliary wall 717 on the positioning groove 71, the displacement component 41 bypasses the limitation of the limiting boss 211 and falls back to the core-gathering point A under the influence of the reset component 3. Example 5

[0240] like Figures 24 to 25 The mechanical pen and its operating method are shown, including an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2, an adjustment component 4, and a trigger assembly 6.

[0241] The aforementioned control component 2 is equipped with a control lever 21.

[0242] The outer rod 1 is provided with a positioning groove 71 and a positioning part 72. The positioning groove 71 is provided with a core-receiving switching wall 711, a core-receiving limiting wall 712, and a core-exiting boss 713. The core-exiting boss 713 is provided with a core-exiting sliding wall 7131. The core-exiting boss 713 and / or the displacement member 41 are also provided with a reverse-pushing auxiliary slope 417. The tail of the tool body 5 abuts against the positioning part 72, the tool body 5 is partially placed in the adjusting member 4, and the reset member 3 is completely placed in the adjusting member 4.

[0243] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves within the positioning groove 71.

[0244] 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.

[0245] The aforementioned control component 2 and adjusting component 4 are slidably sleeved inside the outer rod 1: The core-receiving point A is formed at the angle between the core-receiving switching wall 711 and the core-receiving limiting wall 712. The core-exiting point B is located on the core-exiting sliding wall 7131.

[0246] 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 control lever 21.

[0247] 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.

[0248] When the aforementioned displacement member 41 is located on the core-exit sliding wall 7131, it will move in the tilting direction of the core-exit sliding wall 7131 due to the influence of the core-exit sliding wall 7131 and the reset member 3. Before it completely detaches from the core-exit sliding wall 7131, it will be limited by the control rod 21 on the displacement member 41 and / or the adjusting member 4, preventing the displacement member 41 from completely detaching from the core-exit sliding wall 7131. At this time, the core-exit sliding wall 7131 determines the height position of the displacement member 41. Finally, the displacement member 41 will stop on the core-exit sliding wall 7131, and the position where the displacement member 41 stops at this time is the core-exit point B. At this time, the writing part of the tool body 5 will expose the adjusting member 4, and this is the core-exit state.

[0249] At this time, the writing part of the tool body 5 will expose the adjustment part 4, which is the core-out state.

[0250] 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.

[0251] The aforementioned displacement member 41 is also provided with a displacement catch protrusion 411 or a sliding bead groove, and the aforementioned displacement member 41 itself does not generate The shape of the core-receiving part A of the positioning groove 71 can be adaptively adjusted according to the shape of the displacement protrusion 411, the sliding bead 8 and / or the displacement member 41 sliding in the positioning groove 71.

[0252] The aforementioned core-ejecting boss 713 has a core-ejecting auxiliary slope B1 near the core-receiving end A and / or the displacement member 41 has a core-ejecting auxiliary slope B1 near the core-ejecting end B. The displacement member 41 itself has the ability to deform and bend forward and backward. When the displacement member 41 passes the core-ejecting boss 713, it can cross the core-ejecting boss 713 and reach the core-ejecting end B through the core-ejecting auxiliary slope B1 and the deformation and bending ability of the displacement member 41. With this solution, it must be ensured that after the displacement member 41 reaches the core-ejecting end B, it cannot use its deformation and bending ability to return to the core-receiving end A. For example, barbs, rough textures, increased friction, and / or increased mating contact surfaces can be added to the core-ejecting boss 713.

[0253] The aforementioned trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63. The limiting member 61 passes through the trigger cover 63 and is interconnected with the control member 2, and the control member 2 moves with the limiting member 61. The trigger cover 63 is interconnected with the outer rod 1, and the trigger cover 63 does not move relative to the outer rod 1. 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. When the trigger ring 62 is squeezed by an external force, the trigger auxiliary inclined ring C causes the control member 2 to move upward relative to the positioning groove 71, thereby causing the control rod 21 to move upward, and causing the displacement member 21 to slide from the core exit point B to the core retraction point A.

[0254] This embodiment can additionally achieve reverse push core recovery: keeping the outer rod 1 stationary, the external force pulls the adjusting component 4 upward, and through the reverse push auxiliary slope 417, the above-mentioned displacement component 41 is freed from the restriction of the core exiting boss 713, thereby returning to the core recovery point A.

[0255] Installation method: 1. Insert the control component, trigger cover, trigger ring, and limit component into the outer rod in sequence from top to bottom. The trigger cover and the outer rod should cooperate. The limit component should pass through the trigger ring, trigger cover, and control component to cooperate. 2. Then, install the adjusting part, tool body, reset part and pen changing part into the outer rod in sequence from bottom to top, and make the pen changing part and adjusting part fit together; 3. At this point, the installation is complete. You can check whether the displacement boss 411 is located in the positioning groove 71. If not, adjust the position of the adjusting component to ensure that the displacement boss 411 is placed in the positioning groove 71.

[0256] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the pen should be held upright before the lead can be ejected to ensure a high success rate. Alternatively, an auxiliary reset component can be added directly between the control component and the trigger cover to improve the user experience.

[0257] The core extraction method adopts the second lifting core extraction scheme: keep the outer rod 1 stationary, and use external force to control the adjustment component 4 to move upward. When the displacement component 41 passes the core extraction boss 713, it passes the core extraction auxiliary slope B1 and the deformation and bending ability of the displacement component 41, and reaches the core extraction point B.

[0258] It has both of the following core-collecting methods: 1. Triggering the retraction scheme one: 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 limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement boss 411 loses the restriction of the control member 2 and will slide down along the lead-out sliding wall 7131 to the retraction point A. At this time, the main body of the tool will be completely hidden in the pen changing part D. 2. Reverse push core collection scheme two: Keep the outer rod 1 stationary, pull the adjusting component 4 downward by external force, and through the reverse push auxiliary slope 417, the above displacement component 41 is freed from the restriction of the core exiting boss 713, and thus returns to the core collection point A. Example 6

[0259] like Figures 26 to 27 The mechanical pen and its operating method are shown, including an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2, an adjustment component 4, and a trigger assembly 6.

[0260] The aforementioned control component 2 is equipped with a control lever 21.

[0261] The outer rod 1 is provided with a positioning groove 71. The positioning groove 71 is provided with a core-receiving switching wall 711, a core-receiving limiting wall 712, and a core-exiting boss 713. The core-exiting boss 713 is provided with a core-exiting sliding wall 7131.

[0262] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves within the positioning groove 71.

[0263] The aforementioned adjusting member 4 is further provided with an adjusting abutment portion 42 and an adjusting pressing portion 43. The aforementioned tool body 5 and the resetting member 3 are placed inside the outer rod 1, with the resetting member 3 specifically located between the tool body 5 and the outer rod 1. The tail end of the aforementioned tool body 5 abuts against the lower end of the adjusting abutment portion 42. The tail end of the aforementioned tool body 5 abuts against the adjusting abutment portion 42, and the aforementioned tool body 5 and the resetting member 3 are completely placed within the outer rod.

[0264] The aforementioned control component 2 and adjusting component 4 are slidably sleeved inside the outer rod 1: The core-receiving point A is formed at the angle between the core-receiving switching wall 711 and the core-receiving limiting wall 712. The core-exiting point B is located on the core-exiting sliding wall 7131.

[0265] 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 control lever 21.

[0266] An auxiliary reset component 31 may be provided between the control component 2 and the adjustment component 4. The elastic force of the auxiliary reset component 31 is less than that of the reset component 3.

[0267] 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.

[0268] When the displacement member 41 is located on the core-exit sliding wall 7131, it will move in the tilting direction of the core-exit sliding wall 7131 due to the influence of the core-exit sliding wall 7131 and the reset member 3. Before it completely detaches from the core-exit sliding wall 7131, it will be limited by the control rod 21 on the displacement member 41 and / or the adjusting member 4, so that the displacement member 41 cannot completely detach from the core-exit sliding wall 7131 normally. At this time, the core-exit sliding wall 7131 determines the height position of the displacement member 41. Finally, the displacement member 41 will stop on the core-exit sliding wall 7131, and the position where the displacement member 41 stops at this time is the core-exit point B. At this time, the writing part of the tool body 5 will expose the adjusting member 4, and this is the core-exit state.

[0269] 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.

[0270] The aforementioned displacement member 41 is also provided with a displacement latch 411, and the aforementioned displacement member 41 itself will not deform or bend to the left or right. When it is necessary to move to the left or right, the adjusting member 4 as a whole will move to the left or right.

[0271] The shape of the core-receiving part A of the positioning groove 71 can be adaptively adjusted according to the shape of the displacement protrusion 411, the sliding bead 8 and / or the displacement member 41 sliding in the positioning groove 71.

[0272] The aforementioned core-ejecting boss 713 has a core-ejecting auxiliary slope B1 near the core-receiving end A and / or the displacement member 41 has a core-ejecting auxiliary slope B1 near the core-ejecting end B. The displacement member 41 itself has the ability to deform and bend forward and backward. When the displacement member 41 passes the core-ejecting boss 713, it can cross the core-ejecting boss 713 and reach the core-ejecting end B through the core-ejecting auxiliary slope B1 and the deformation and bending ability of the displacement member 41. With this solution, it must be ensured that after the displacement member 41 reaches the core-ejecting end B, it cannot use its deformation and bending ability to return to the core-receiving end A. For example, barbs, rough textures, increased friction, and / or increased mating contact surfaces can be added to the core-ejecting boss 713.

[0273] An auxiliary reset component 31 is provided between the aforementioned control component 2 and trigger component 6.

[0274] The outer rod 1 is provided with a connecting body 11. The trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63. The limiting member 61 passes through the trigger cover 63 and is connected to the connecting body 11. 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. When the trigger ring 62 is squeezed by an external force, the trigger auxiliary inclined ring C can cause the control member 2 to move downward relative to the positioning groove 71, thereby causing the control rod 21 to move downward, and causing the displacement member 21 to slide from the core exit point B to the core retraction point A.

[0275] Triggering method scheme one involves indirectly controlling the upward movement of control component 2 via triggering component 6. Triggering method scheme two involves indirectly controlling the downward movement of control component 2 via triggering component 6. The choice of triggering method depends primarily on the direction in which the control component needs to move.

[0276] Installation method: 1. First, install the trigger cover, trigger ring, and limiting component into the outer rod in sequence from top to bottom. The limiting component passes through the trigger ring, trigger cover, and connecting body to cooperate. 2. Insert the positioning component, auxiliary reset component, adjustment component, pen refill, reset component, and pen replacement part into the outer rod in sequence from bottom to top, and mate the pen replacement part with the outer rod; 3. Finally, assemble the pressing and adjusting parts.

[0277] The core extraction method adopts the second core extraction scheme: keep the outer rod 1 still, and use external force to control the adjustment component 4 to move upward. When the displacement component 41 passes the core extraction boss 713, it passes the core extraction auxiliary slope B1 and the deformation and bending ability of the displacement component 41, and reaches the core extraction point B. The retraction method adopts the trigger retraction scheme one: when the product of this invention is placed directly on a storage item such as a desktop, school bag, 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 limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement boss 411 loses the restriction of the control member 2 and will slide down the lead-out sliding wall 7131 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 7

[0278] like Figures 28 to 32 The diagram illustrates a mechanical pen and its operating method. It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2, an adjustment component 4, a trigger assembly 6, and a positioning component 7.

[0279] The aforementioned control component 2 is equipped with a control lever 21. The tail of the aforementioned tool body 5 abuts against the positioning component 7. Part of the aforementioned tool body 5 is placed within the adjusting component 4, and the aforementioned reset component 3 is completely placed within the adjusting component 4. The aforementioned positioning component 7 is installed inside the outer rod 1 and should not move up or down significantly; ideally, it should not move up or down at all. The positioning component 7 is provided with a positioning groove 71. The positioning groove 71 is provided with a core-receiving switching wall 711, a core-receiving limiting wall 712, and a core-exiting boss 713. The core-exiting boss 713 is provided with a core-exiting sliding wall 7131.

[0280] The aforementioned adjusting member 4 is provided with a displacement member 41, which moves within the positioning groove 71.

[0281] 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 member 7.

[0282] The aforementioned control component 2 and adjusting component 4 are slidably sleeved inside the outer rod 1: The core-gathering point A is formed at the angle between the core-gathering switching wall 711 and the core-gathering limiting wall 712.

[0283] 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.

[0284] When the aforementioned displacement member 41 is located on the core-exit sliding wall 7131, it will move in the tilting direction of the core-exit sliding wall 7131 due to the influence of the core-exit sliding wall 7131 and the reset member 3. Before it completely detaches from the core-exit sliding wall 7131, it will be limited by the control rod 21 on the positioning member 7, displacement member 41 and / or adjusting member 4, so that the displacement member 41 cannot completely detach from the core-exit sliding wall 7131 normally. At this time, the core-exit sliding wall 7131 determines the height position of the displacement member 41. Finally, the displacement member 41 will stop on the core-exit sliding wall 7131, and the position where the displacement member 41 stops at this time is the core-exit point B. At this time, the writing part of the tool body 5 will expose the adjusting member 4, and this is the core-exit state.

[0285] 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 control lever 21. When the control lever 21 disengages from the displacement component 41, the displacement component 41 will move from the core exit point B to the core retraction point A.

[0286] The control lever 21 can only move up and down or forward and backward relative to the positioning component 7, but cannot move left and right.

[0287] The aforementioned displacement component 41 is provided with a movable groove 81, and a sliding ball 8 is provided between the movable groove 81 and the positioning groove 71. The sliding ball 8 directly contacts the displacement component 41 and the positioning groove 71 instead of the other component. This design eliminates the need for adjustment components to rotate or translate, resulting in greater stability, simpler manufacturing, easier installation, and smoother operation. The aforementioned movable groove 81 includes a movable straight groove, a movable arc groove, and a movable annular groove. The movable straight groove has a straight trajectory, suitable for planar positioning grooves; the movable arc groove has an arc trajectory, suitable for curved surface positioning grooves; and the movable annular groove has an annular trajectory, suitable for toroidal surface positioning grooves.

[0288] When the control lever 21 needs to restrict the displacement latch 411, the sliding bead 8, or the displacement member 41 located in the positioning groove 71, a control groove 715 is also provided in the positioning groove 71. The control lever 21 passes through the control groove 715 to restrict the displacement latch 411, the sliding bead 8, or the displacement member 41 located in the positioning groove 71 from disengaging from the core exit sliding wall 7131.

[0289] The aforementioned core-ejecting boss 713 is further provided with a core-ejecting guide wall 7132 on the side near the core-receiving point A. The aforementioned positioning groove 71 is also provided with a core-ejecting switching wall 714. A core-ejecting channel B2 is also provided between the aforementioned core-ejecting switching wall 714 and the core-ejecting boss 713. When the aforementioned displacement member 41 moves upward from the core-receiving point A, it is influenced by the core-ejecting guide wall 7132 and enters the core-ejecting channel B2. Subsequently, it passes through the core-ejecting switching wall 714 and reaches above the core-ejecting point B. At this point, if the external force is released, the displacement member 41 will fall back to the core-ejecting point B.

[0290] An auxiliary reset component 31 is provided between the aforementioned control component 2 and trigger component 6.

[0291] The aforementioned trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63. The limiting member 61 passes through the trigger cover 63 and is interconnected with the control member 2, and the control member 2 moves with the limiting member 61. The trigger cover 63 is interconnected with the outer rod 1, and the trigger cover 63 does not move relative to the outer rod 1. 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. When the trigger ring 62 is squeezed by an external force, the trigger auxiliary inclined ring C causes the control member 2 to move upward relative to the positioning groove 71, thereby causing the control rod 21 to move upward, and causing the displacement member 21 to slide from the core exit point B to the core retraction point A.

[0292] To facilitate the insertion of the sliding ball into the movable groove, the positioning groove is also provided with a sliding ball insertion groove. The depth of the sliding ball insertion groove is deeper than the other parts of the positioning groove. At the same time, an insertion slope is provided between the sliding ball insertion groove and the other parts of the positioning groove. The insertion slope is used to buffer the insertion of the sliding ball and facilitate the transition of the sliding ball from the sliding ball insertion groove into the positioning groove.

[0293] Installation method: 1. First, assemble the positioning component, sliding ball, and adjusting component into an adjusting assembly. Insert the positioning component into the adjusting component, and then insert the sliding ball into the positioning groove and the movable groove through the sliding ball insertion groove. At this point, the adjusting assembly is complete. 2. Then, install the adjustment component into the outer rod from top to bottom. The adjustment component will not be able to move down too much due to the limit between the positioning part and the outer rod. After the positioning part stops in the installation position, install the control part, auxiliary reset part and trigger cover into the outer rod from top to bottom in sequence. 3. Next, place the trigger ring on the trigger cover, pass the limiting component through the trigger ring and the trigger cover, and assemble it with the control component; then the assembly of the pen is roughly complete. 4. Finally, insert the tool body, reset piece, and pen changer into the adjustment unit from bottom to top, and then install the pen changer and adjustment piece into place.

[0294] The core ejection method adopts the lifting core ejection scheme one: the external force control adjustment component 4 moves upward, and through the switching long wall 71B on the positioning groove 71, it moves between the core ejection boss 713 and the control component 2, and stops at the core ejection point B; The retraction method adopts the trigger retraction scheme one: the product of this invention is placed directly on a storage item such as a desktop, school bag, pencil case or pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement part 821 loses the restriction of the control member 2 and will slide down the lead-out sliding wall 7131 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 8

[0295] like Figures 33-36 The diagram illustrates a mechanical pen and its operating method. It includes an outer rod 1, a reset component 3, a tool body 5, and an adjustment module. The adjustment module includes a control component 2, an adjustment component 4, a trigger assembly 6, and a positioning component 7.

[0296] The aforementioned control component 2 is equipped with a control lever 21.

[0297] The aforementioned positioning component 7 is installed inside the outer rod 1 and should not move up or down significantly; ideally, it should not move up or down at all. The positioning component 7 has a positioning groove 71. The positioning groove 71 has a core-receiving switching wall 711, a core-receiving limiting wall 712, and a core-exiting boss 713. The core-exiting boss 713 has a core-exiting sliding wall 7131. The tail of the tool body 5 abuts against the positioning component 7. The tool body 5 is partially placed within the adjusting component 4, and the reset component 3 is completely placed within the adjusting component 4. The aforementioned adjusting member 4 is provided with a displacement member 41, which moves within the positioning groove 71.

[0298] 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 member 7.

[0299] The aforementioned control component 2 and adjusting component 4 are slidably sleeved inside the outer rod 1: The core-gathering point A is formed at the angle between the core-gathering switching wall 711 and the core-gathering limiting wall 712.

[0300] 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.

[0301] When the aforementioned displacement member 41 is located on the core-exit sliding wall 7131, it will move in the tilting direction of the core-exit sliding wall 7131 due to the influence of the core-exit sliding wall 7131 and the reset member 3. Before it completely detaches from the core-exit sliding wall 7131, it will be limited by the control rod 21 on the positioning member 7, displacement member 41 and / or adjusting member 4, so that the displacement member 41 cannot completely detach from the core-exit sliding wall 7131 normally. At this time, the core-exit sliding wall 7131 determines the height position of the displacement member 41. Finally, the displacement member 41 will stop on the core-exit sliding wall 7131, and the position where the displacement member 41 stops at this time is the core-exit point B. At this time, the writing part of the tool body 5 will expose the adjusting member 4, and this is the core-exit state.

[0302] 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 control lever 21. When the control lever 21 disengages from the displacement component 41, the displacement component 41 will move from the core exit point B to the core retraction point A.

[0303] The control lever 21 can only move up and down or forward and backward relative to the positioning component 7, but cannot move left and right.

[0304] The aforementioned displacement member 41 is also provided with a rotating through hole 41F and a rotating fastener 4121. The aforementioned rotating through hole 41F is also provided with a rotating member 82. The aforementioned rotating member 82 is also provided with a rotating boss 412, a displacement part 821 and three rotating contact bosses 82H. After the aforementioned rotating boss 412 is pressed into the rotating through hole 41F, the rotating member 82 can rotate relative to the rotating through hole 41F. The other end of the rotating member 82 is provided with a displacement part 821. The aforementioned displacement part 821 replaces the displacement member 41 and directly contacts the positioning groove 71. The aforementioned rotating fastener 4121 is divided into a clamping part 4131, a deformation groove 713K and a snap-in part 4132. The aforementioned rotating fastener 4121 is snapped into the side of the displacement member 41 by the snap-in part 4132. The displacement member 41 is also provided with a corresponding clamping groove 41Y. After the snap-in part 4132 is snapped into the clamping groove 41Y, the clamping part 4131 and the deformation groove 713K continuously apply clamping force to the rotating member 82, thereby making the left and right rotation of the rotating member 82 have a certain damping effect, thus overcoming the interference of gravity.

[0305] The aforementioned rotating contact boss 82H can effectively reduce the friction between the rotating part 82 and the displacement part 41, thereby ensuring that it can overcome gravity interference while having sensitive adjustability and improving the actual operating experience.

[0306] A certain amount of space needs to be reserved on the rear side of the clamping part 4131 to allow the clamping part 4131 to deform backward.

[0307] This embodiment employs a design where the rotating boss is placed on the rotating component, and the rotating boss is positioned higher than the displacement part 821. This fully utilizes the internal space, reducing the overall length and allowing for greater design flexibility, enabling the inclusion of more pen refill sizes. Furthermore, because the main body of the displacement part 41 is mounted on the upper, middle side, a rotating opening 4K is provided between the displacement part 41 and the adjusting part 4. The displacement part 821 of the rotating component 82 moves into the positioning groove 71 through the rotating opening 4K.

[0308] The aforementioned core-ejecting boss 713 is further provided with a core-ejecting guide wall 7132 on the side near the core-receiving point A. The aforementioned positioning groove 71 is also provided with a core-ejecting switching wall 714. A core-ejecting channel B2 is also provided between the aforementioned core-ejecting switching wall 714 and the core-ejecting boss 713. When the aforementioned displacement member 41 moves upward from the core-receiving point A, it is influenced by the core-ejecting guide wall 7132 and enters the core-ejecting channel B2. Subsequently, it passes through the core-ejecting switching wall 714 and reaches above the core-ejecting point B. At this point, if the external force is released, the displacement member 41 will fall back to the core-ejecting point B.

[0309] The aforementioned trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63. The limiting member 61 passes through the trigger cover 63 and is interconnected with the control member 2, and the control member 2 moves with the limiting member 61. The trigger cover 63 is interconnected with the outer rod 1, and the trigger cover 63 does not move relative to the outer rod 1. 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. When the trigger ring 62 is squeezed by an external force, the trigger auxiliary inclined ring C causes the control member 2 to move upward relative to the positioning groove 71, thereby causing the control rod 21 to move upward, and causing the displacement member 21 to slide from the core exit point B to the core retraction point A.

[0310] The aforementioned positioning groove 71 features a multi-layered staggered design. A smooth slope D3 connects the bottom layer D2 to the top layer D1 in this multi-layered staggered design. For example, the area related to the core-receiving point A forms the top layer, while the area related to the core-exiting point B forms the bottom layer, which is lower than the core-receiving point A. Therefore, after the displacement member 41 enters the core-exiting point B from the core-receiving point A, it is difficult to return to the core-receiving point A via the same path, forming a loop similar to a one-way valve. The smooth slope, however, facilitates the return of the displacement member 41 from the end point of the bottom layer to the beginning point of the top layer.

[0311] Installation method: 1. First, assemble the positioning component, rotating component, and adjusting component into an adjusting assembly. One end of the rotating component is fitted onto the rotating boss located on the adjusting component. Insert the positioning component into the adjusting component, and then insert the displacement part of the other end into the positioning groove. At this point, the adjusting assembly is complete. 2. Then, install the adjustment component into the outer rod from top to bottom. The adjustment component will not be able to move down too far due to the limit between the positioning part and the outer rod. After the positioning part stops in the installation position, continue to install the control part and the trigger cover into the outer rod from top to bottom. 3. Next, place the trigger ring on the trigger cover, pass the limiting component through the trigger ring and the trigger cover, and assemble it with the control component; then the assembly of the pen is roughly complete. 4. Finally, insert the tool body, reset piece, and pen changer into the adjustment unit from bottom to top, and then install the pen changer and adjustment piece into place.

[0312] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the pen should be held upright before the lead can be ejected to ensure a high success rate. Alternatively, an auxiliary reset component can be added directly between the control component and the trigger cover to improve the user experience.

[0313] The core ejection method adopts the lifting core ejection scheme one: the external force control adjustment component 4 moves upward, and through the switching long wall 71B on the positioning groove 71, it moves between the core ejection boss 713 and the control component 2, and stops at the core ejection point B; The retraction method adopts the trigger retraction scheme one: the product of this invention is placed directly on a storage item such as a desktop, school bag, pencil case or pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limiting member 61, and the limiting member 61 will move upward, thereby driving the control member 2 to move upward. When the control member 2 moves upward, the displacement part 821 loses the restriction of the control member 2 and will slide down the lead-out sliding wall 7131 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 9

[0314] like Figures 37-41 The aforementioned mechanical pen and its operating method include an outer rod 1, a reset component 3, a tool body 5, a control component 2, an adjustment component 4, and a positioning component 7; The aforementioned positioning component 7 is provided with a positioning groove 71; The aforementioned adjusting member 4 is provided with a displacement member 41, which moves movably within the positioning groove 71.

[0315] The aforementioned adjusting member 4 is also provided with a side push part 4A; the aforementioned outer rod 1 is provided with a side push groove 1A to accommodate the sliding of the side push part 4A; through the side push part 4A, the adjusting member can be completely hidden inside the outer rod or partially exposed, so that the core can be released and retrieved simultaneously by reverse lifting, and the adjusting member 4 can be controlled by the side push part 4A to release and retrieve the core.

[0316] The outer rod 1 is also equipped with a trigger component 6.

[0317] The outer rod 1 is provided with a cover 14, and the cover 14 is provided with a connecting body 11; the trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63; 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 in contact with 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; The aforementioned displacement member 41 is also provided with a displacement locking protrusion 411, a sliding bead groove, or a rotating boss 412. A sliding bead is also provided between the sliding bead groove and the positioning groove 71. The aforementioned rotating boss 412 is also provided with a rotating member 82. One end of the rotating member 82 is sleeved on the rotating boss 412. The rotating member 82 can rotate relative to the rotating boss 412. The other end of the rotating member 82 is provided with a displacement part 821. The displacement part 821, the sliding bead, or the displacement locking protrusion 411 directly contacts the positioning groove 71 in place of the displacement member 41. When it is necessary to move to the left or to the right, the adjusting member 4 as a whole moves to the left or to the right. The aforementioned positioning groove 71 is also provided with a core-exit limiting wall 716 and a core-receiving auxiliary wall 717.

[0318] An auxiliary reset component 31 is provided between the control component 2 and the positioning component 7. The aforementioned displacement member 41 is also provided with a rotating abutment boss 413 for abutting the adjusting rotating member 82.

[0319] The aforementioned positioning groove 71 is equipped with a core-receiving switching wall 711. Because the core-receiving switching wall 711 is located at the fallback position, which is also the area with the longest travel, the slope requirement is low, and it is very easy to fall back. However, this long-distance movement will introduce more variables for the core-exiting process. Therefore, by changing the core-receiving point A to be located directly below or near the core-exiting boss 713 through the core-receiving switching wall 711, the stability during core-receiving switching and core-exiting will be improved. The aforementioned positioning component 7 is also provided with a control groove 715 for accommodating the up-and-down movement of the control lever 21; The aforementioned positioning groove 71 is also provided with an anti-detachment boss 719, and a return channel 71A is provided between the aforementioned limiting boss 211 and the anti-detachment boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211. The aforementioned adjusting member 4 is also provided with an adjusting contact part 42; The aforementioned positioning component 7 is engaged between the maximum limiting boss 77 on the outer rod 1 and the cover 14; The rotating boss 412 may also be provided with a rotating fastener 4121; the rotating fastener 4121 is provided with a rotating locking part 41211, a pressure flap 41212 and a pressure column 41213; the pressure column 41213 abuts against the rotating member 82, while the pressure flap 41212 provides tough rebound, and the rotating locking part 41211 is locked into the rotating boss 412, so that the rotating fastener 4121 can be stably fixed on the rotating boss 412.

[0320] The aforementioned adjusting member 4 is provided with a rotating stabilizing boss 45; the aforementioned displacement member 41 is also provided with a rotating abutting boss 413 for abutting the adjusting rotating member 82; Installation method: 1. The adjusting component, rotating component, and positioning component are assembled into an adjusting assembly, which is then inserted into the outer rod from top to bottom; 2. Next, install the auxiliary reset component, control component, cover, trigger cover, trigger ring, and limit rod into the outer rod in sequence from top to bottom; the cover and the outer rod are threaded together, and the limit component and the connecting body on the cover are threaded together again. 3. Pass the side push part through the side of the outer rod and directly snap it into the adjusting part. 4. Finally, insert the main body of the tool, the reset piece, the pen grip T, and the pen changing part into the adjusting rod in sequence, and assemble the pen changing part with the outer rod.

[0321] The core ejection method adopts the third side-push core ejection scheme: the external force controls the adjustment component 4 to move downward through the side push part, and the aforementioned displacement component 41 moves downward from the core receiving point A. Under the influence of the core ejection guide wall 7132, it enters the core ejection channel B2, and then reaches above the core ejection point B by switching the long wall 71B. At this time, the external force is released, and the displacement component 41 will fall back to the core ejection point B, and the core ejection is completed.

[0322] The following two methods are used simultaneously for core winding: 1. Side-push core-gathering scheme one: When the external force side-push part 1A controls the adjustment part 4 to move further down, the displacement part 41 will continue to move down. Then, through the core-gathering auxiliary wall 717 on the positioning groove 71, the displacement part 41 bypasses the limitation of the limiting boss 211 and returns to the core-gathering point A through the rebound force of the reset part 3.

[0323] 2. Triggering Core Retraction Scheme 1: The trigger ring collects external forces from all around and transmits the collected forces to the control component through the trigger cover, thereby causing the control component 2 to move. This causes the displacement component 41 to break free from the restriction of the control component 2. The displacement component 41 will then be affected by the reset component 3 and move, thus achieving core retraction.

[0324] The core ejection scheme used in this embodiment is quite special. Compared with the previous embodiments, the adjustment component is not operated through the tail end or the front end, but is operated from the side using a side push part. The side push part can be integrated with the adjustment component or be a separate accessory. When integrated, the side push part needs to be able to deform backward relative to the adjustment component for easy installation. In this embodiment, a separate accessory snap-fit ​​method is used. Example 10

[0325] like Figures 42-46 The aforementioned mechanical pen and its operating method include an outer rod 1, a reset component 3, a tool body 5, a control component 2, an adjustment component 4, and a positioning component 7; The aforementioned positioning component 7 is provided with a positioning groove 71; The aforementioned adjusting member 4 is provided with a displacement member 41, which moves movably within the positioning groove 71.

[0326] The outer rod 1 is also provided with a pressing groove 1B; a side pressing member 1B1 is also provided in the pressing groove 1B; the adjusting member 4 is provided with a core-exit pressing auxiliary slope 1B2 that cooperates with the side pressing member 1B1; the side pressing member 1B1 moves back and forth relative to the pressing groove 1B, and when the side pressing member 1B1 moves backward, it will squeeze the core-exit pressing auxiliary slope 1B2, thereby causing the adjusting member 4 to move down and press the side pressing member 1B1 to the bottom, which will cause the displacement member 41 to move from the core-receiving position. Point A moves to point B where the core is exiting. The conversion ratio between the pressing stroke of the side press 1B1 and the downward movement of the adjusting member 4 is affected by the slope of the core exiting pressing auxiliary slope 1B2. The smaller the slope of the core exiting pressing auxiliary slope 1B2, the higher the conversion ratio between the pressing stroke of the side press 1B1 and the downward movement of the adjusting member 4. This means that the side press moves a shorter distance, which can ensure that the adjusting member moves a greater distance, thereby meeting the minimum requirement for the core exiting displacement of the adjusting member.

[0327] The aforementioned side press 1B1 is provided with an inserting auxiliary card protrusion 1B2, and the pressing groove 1B is also provided with an inserting auxiliary groove 1B3 that cooperates with the inserting auxiliary card protrusion 1B4. When the side press 1B1 is pressed all the way down, the adjusting member 4 moves down into place, so that after normal core ejection, because the position of the adjusting member 4 has been fixed in the core ejection state through the reset member 3 and the positioning member, the adjusting member 4 will not apply a reset force to the side press 1B1 at this time. Therefore, the side press 1B1 will sway back and forth, which will affect the writing process of the core ejection state. To avoid unnecessary interference, the addition of an auxiliary insert 1B4 and an auxiliary insert 1B3 ensures that when the side press 1B1 is pressed down to the bottom, while the adjusting member 4 controls the core ejection, the side press 1B1 will be temporarily fixed to the outer rod 1. This temporary fixation is not reliable. When the automatic core retraction is triggered, the side press 1B1 will be affected by the force applied to the adjusting member 4 by the reset member 3, causing the adjusting member 4 to reset. Then, the core ejection pressing auxiliary slope 1B2 will cause the side press 1B1 to disengage from the temporary fixation and reset, waiting for the next use.

[0328] When the side ejection or side pressing ejection method is used, the tail end of the tool body does not collide with the positioning component, but with the adjustment component, and the auxiliary reset component is also changed to be located between the control component and the positioning component.

[0329] The outer rod 1 is also equipped with a trigger component 6.

[0330] The outer rod 1 is provided with a cover 14, and the cover 14 is provided with a connecting body 11; the trigger assembly 6 includes a limiting member 61, a trigger ring 62, and a trigger cover 63; 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 in contact with 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; The aforementioned displacement member 41 is also provided with a displacement locking protrusion 411, a sliding bead groove, or a rotating boss 412. A sliding bead is also provided between the sliding bead groove and the positioning groove 71. The aforementioned rotating boss 412 is also provided with a rotating member 82. One end of the rotating member 82 is sleeved on the rotating boss 412. The rotating member 82 can rotate relative to the rotating boss 412. The other end of the rotating member 82 is provided with a displacement part 821. The displacement part 821, the sliding bead, or the displacement locking protrusion 411 directly contacts the positioning groove 71 in place of the displacement member 41. When it is necessary to move to the left or to the right, the adjusting member 4 as a whole moves to the left or to the right. The aforementioned positioning groove 71 is also provided with a core-exit limiting wall 716 and a core-receiving auxiliary wall 717.

[0331] An auxiliary reset component 31 is provided between the control component 2 and the positioning component 7.

[0332] The aforementioned displacement member 41 is also provided with a rotating abutment boss 413 for abutting the adjusting rotating member 82.

[0333] The aforementioned positioning groove 71 is provided with a core-receiving switching wall 711. Because the core-receiving switching wall 711 is located at the fall-off position, which is also the area with the longest travel, the slope requirement is low, and it is very easy to fall back. However, this long-distance movement will have more variables for the core-exiting process. Therefore, by changing the core-receiving point A to be directly below or near the core-exiting boss 713 through the core-receiving switching wall 211, it will help to improve the stability of core-receiving switching and core-exiting.

[0334] The aforementioned positioning component 7 is also provided with a control groove 715 for accommodating the up-and-down movement of the control lever 21; The aforementioned positioning groove 71 is also provided with an anti-detachment boss 719, and a return channel 71A is provided between the aforementioned limiting boss 211 and the anti-detachment boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211. The aforementioned adjusting member 4 is also provided with an adjusting contact part 42; the tail end of the aforementioned tool body 5 abuts against the adjusting contact part 42.

[0335] The aforementioned rotating component is also provided with a rotating auxiliary platform and / or a rotating mounting notch. The rotating auxiliary platform and the displacement component and / or the rotating abutment boss generate abutment. The rotating auxiliary platform can effectively help the rotating component counteract the interference of gravity. The rotating mounting notch can be used when the rotating boss is integrated between the rotating auxiliary platform and the displacement component, making it difficult to install the rotating component. In this case, the rotating component can be quickly, effectively and securely installed in place.

[0336] The aforementioned adjusting member 4 is provided with a rotating stabilizing boss 45; the aforementioned displacement member 41 is also provided with a rotating abutting boss 413 for abutting the adjusting rotating member 82, and the aforementioned rotating member 82 is also provided with a rotating auxiliary platform 822 and / or a rotating mounting notch 823. The aforementioned core-ejecting boss 713 may be provided with deformation slots 713K. Only one side and both sides of the core-ejecting boss 713 need to have deformation slots 713K, thus enabling the core-ejecting boss 713 to have deformation capability. Therefore, the displacement member 41 can pass over the core-ejecting boss 713 without requiring deformation capability. Installation method: 3. The adjusting parts, rotating parts, and positioning parts are assembled into an adjusting assembly, which is then inserted into the outer rod from top to bottom; 4. Next, install the auxiliary reset component, control component, cover, trigger cover, trigger ring, and limit rod into the outer rod in sequence from top to bottom; the cover and the outer rod are threaded together, and the limit component and the connecting body on the cover are threaded together again. 3. Pass the side pusher through the side of the outer rod and insert it directly into the outer rod. 4. Finally, insert the main body of the tool, the reset piece, the pen grip T, and the pen changing part into the adjusting rod in sequence, and assemble the pen changing part with the outer rod.

[0337] The core ejection method adopts the second side-press core ejection scheme: the external force controls the side-press component 1B1 to move backward, then the adjusting component 4 will move the displacement component 41 downward together. Thus, when the displacement component 41 passes the core ejection boss 713, it passes the core ejection auxiliary slope B1 and / or the deformation and bending ability of the displacement component 41, and reaches the core ejection point B, then the core ejection is completed.

[0338] The core-collecting method adopts the trigger-based core-collecting scheme one: the trigger ring collects the external force from all around, and the trigger cover transmits the force collected by the trigger ring to the control component, thereby causing the control component 2 to move, so that the displacement component 41 is freed from the restriction of the control component 2. Then the displacement component 41 will be affected by the reset component 3 to move, thereby realizing core collection.

[0339] The core ejection scheme used in this embodiment is quite unique. Compared with the previous embodiments, the adjustment component is not operated through the tail end or the front end, but is operated from the side with the assistance of the side pressing part. This provides a brand-new core ejection operation method, and also takes into account the optimal core retraction method of triggering core retraction.

[0340] In this embodiment, the rotating part is installed by side snapping. Because the rotating boss in this embodiment is integrally formed between the rotating stabilizing boss 45 and the displacement part 41, the rotating part 82 cannot be inserted into the rotating boss by front and rear fitting. Therefore, the rotating boss is inserted by side snapping.

[0341] Additional points included in all of the above embodiments 1-10: 1. The surfaces of the control lever 21 and the trigger ring should be as smooth as possible to reduce friction, which can reduce the force required for triggering and further improve the triggering effect.

[0342] 2. In order to facilitate the cooperation with the fall-off auxiliary slope 213, the core-exiting boss 713 is provided with a corresponding fall-off small slope 7133. 3. The slope area of ​​the fall-off small slope 7133 is small, so it will not cause the core-exiting boss 713 to fail to cooperate effectively with the displacement member 41.

[0343] 4. In order to facilitate better cooperation with the core-exiting auxiliary slope B1, the core-exiting boss 713 is provided with a corresponding core-exiting small slope 7134. The slope area of ​​the core-exiting small slope 7134 is small and will not affect the cooperation between the displacement member 41 and the switching long wall 71B.

[0344] 5. To ensure the stability of the entire structure, when the positioning groove 71 is provided on the outer rod 1, the outer rod 1 is also provided with a core-receiving limiting wall 712. When the positioning groove 71 is provided on the positioning member 7, the positioning groove 71 is also provided with a core-receiving limiting wall 712 or the inner wall of the outer rod 1 is equal to the core-receiving limiting wall 712, which serves as a limiting function.

[0345] 6. The outer diameter of the trigger ring 62 is larger than the outer diameter of the outer rod 1. An extension rod 23 may also be provided at the lower end of the control component 2. A trigger ramp 621 is added to the lower end of the trigger ring 62. The extension rod 23 can solidify the internal structure, prevent the adjusting component 4 from shaking and / or detaching from the outer rod 1, prevent unnecessary shaking and rotation of the control component 2 itself, and provide a limit for the control component 2, thereby better stabilizing the internal structure. The inclination angle of the trigger ramp is determined by the set trigger inclination angle. For example, if the inclination is 10°, triggering the core retraction can be completed, then the inclination angle of the ramp should be above 10° to improve the triggering effect.

[0346] 7. The inner diameter of the aforementioned core output chuck 73 is reduced inward, so that the inner diameter of the core output chuck 73 is smaller than the outer diameter of the core receiving chuck 74. A chuck switching ramp 731 is provided on the lower side of the aforementioned core output chuck 73.

[0347] Additional points included in all of the above embodiments 1-10: 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.

[0348] 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.

[0349] 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.

[0350] 4. The elastic force of the auxiliary reset component 31 is less than that of the reset component 3.

[0351] Special supplementary notes: 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.

[0352] 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.

[0353] 3. Regarding the design that prevents the adjusting member 4 from easily detaching 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 by 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.

[0354] 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.

[0355] 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.

[0356] 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.

[0357] 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.

[0358] 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.

[0359] 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.

[0360] 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.

[0361] 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.

[0362] 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.

[0363] 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.

[0364] 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.

[0365] 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.

[0366] 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.

[0367] 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.

[0368] 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.

[0369] 19. After the positioning component is installed, it can be prevented from moving up and down by the limiting mechanism of the trigger cover and the limiting ring platform 12 or by the limiting mechanism of the outer rod itself, thereby ensuring the accuracy of operation.

[0370] 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.

[0371] 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 adjustment part does not need to be separated into a pen-changing section, especially when the core is pressed out. At this time, the adjustment 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.

[0372] 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.

[0373] 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.

[0374] 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.

[0375] 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. 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.

[0376] 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.

[0377] 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.

[0378] 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.

[0379] 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.

[0380] 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.

[0381] 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.

[0382] 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.

[0383] 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.

[0384] 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.

[0385] 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.

[0386] 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 limiting boss, the adjusting component can cross over the limiting boss 211 using auxiliary methods such as a fall-back auxiliary ramp. However, for safety reasons, the adjusting component should 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 crosses over from above or below depends on the orientation of the positioning groove in the proposed solution, which is determined by whether a lifting or pressing solution is used. For example, first, move around from the core exit point B to above or below the limiting boss 211, and then use the force of the reset component to bounce up or down. When it contacts the upper or lower part of the limiting boss 211, the displacement component 41 crosses over the limiting boss 211 using the fall-back auxiliary ramp, thereby reaching the other side opposite to the fall-back auxiliary ramp, thus achieving core retraction.

[0387] 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. 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; 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; 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. 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. To facilitate labeling and prevent consumer confusion, it is best to label the scale lines indicating the required length of the different tool bodies in the core-out and core-retracting states. 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. 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. 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.

[0388] 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.

[0389] 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.

[0390] 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.

[0391] 41. The explanation for the relative stability of the two positional states achieved by the 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-out or core-receiving state by moving its position within the positioning groove. Switching between the two positional relationships requires the adjusting component to move 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-receiving 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 core exit point is as follows: 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 controlling component and the core exit boss in the positioning groove. Although the core exit boss is relatively fixed, the controlling component is dynamically movable. Thus, the existence of the core exit point can be dynamically determined by the controlling component. When the controlling 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 retraction point. When the controlling 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.

[0392] 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. 43. To facilitate production, the required rotating boss can be installed on the adjusting part as a separate accessory.

[0393] 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.

[0394] 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: 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, and the reset component and the front end of the tool body are 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, and in this case, the reset component and the front end of the tool body are basically located inside the outer rod. 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. 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. Fourth, the position of the positioning groove is variable; it can be placed on the positioning component or the outer rod, resulting in different visual effects and actual production conditions. V. The shape and structure of the positioning groove are varied. The structure of the positioning groove can also have many variations depending on the different operational functions to be achieved. The examples listed in the embodiments of this invention are only a part of the application. Other application scenarios can be supplemented and adjusted according to the actual situation. VI. 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 be improved by adding some stabilizing structures. VII. 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. 8. The triggering component is versatile. The triggering component can be selected to move the limiting member or the trigger cover as needed, or it can move through the trigger rod. The triggering forms of this invention are very diverse. This invention only lists a part of them. 9. 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. 10. The adjusting components are highly variable, with a very wide range of adjustments, achieving different functions and effects. They can be partially exposed at the top of the outer rod, partially exposed at the bottom, 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 adjusting components in the embodiments look completely different from the same part because the range of variations is so large, and the functions and effects achieved 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.

[0395] 46. ​​The rotating part is a metal hook, or it can be a metal irregular structure or a plastic irregular structure. Its main function is to provide a cooperating part for left and right turning.

[0396] 47. The aforementioned rotating boss 412 may also be provided with a rotating fastener 4121. The rotating fastener is installed as a separate accessory, allowing for a choice between a tighter or looser fit. A tighter fit, while ensuring the rotating component can rotate normally left and right, can directly overcome the interference of gravity. The contact surface between the rotating fastener and the rotating component can also be appropriately designed and modified to improve the actual performance. The rotating stabilizing boss 45 can also apply pressure to the rotating component to some extent using the principle of the rotating fastener, thereby overcoming the interference of gravity. The rotating stabilizing boss 45 and the rotating fastener 4121 can coexist. When both are present, the rotating stabilizing boss 45 needs to ensure the rotating fastener 4121 can be installed normally, such as by bypassing the rotating fastener 4121 or providing a through hole to facilitate its installation.

[0397] 48. The adjustment part and the pen changing part mentioned above can be connected by magnetic attraction, snap-fit, or threaded connection. The displacement direction and contact part of the control rod 21, which is connected by magnetic attraction and rotatable snap-fit, will also determine and affect the force required for triggering. In order to trigger better, although the control rod 21 will contact the displacement limiting part 41, the main bearing point should be designed on the core-exiting boss 713 in the positioning part groove. The core-exiting boss 713 mainly bears the force of the reset part 3, ensuring that when the control rod 21 is pulled out to release the limit and trigger the core retraction, the force required is only a contact force.

[0398] 49. 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.

[0399] 50. The function of the rotating fastener 4121 mentioned above can also be directly integrated into the rotating boss. The rotating boss is provided with pressure flaps 41212. After the rotating part is directly snapped into the rotating boss, the pressure flaps can achieve the clamping effect without pressure posts. However, when the rotating fastener is a separate accessory, using pressure posts can save more material and has better resilience. Of course, when the rotating fastener is integrated into the rotating boss, it is also possible to use pressure posts at the same time.

[0400] 51. The displacement direction and the degree of contact force of the control element 21 greatly affect the triggering force. The displacement direction mainly affects the principle and structure of contact, thus influencing the degree of contact force. The degree of contact force is directly proportional to the triggering force; the lower the contact force, the lower the triggering force. Therefore, reducing the contact force can also reduce the triggering force. The choice of displacement direction is crucial because it also determines the stability during writing. The displacement direction will have different effects depending on the actual internal structure design. Taking the current internal structure as a standard, when the control element 21 moves up and down or back and forth, the contact force will be relatively reduced. However, when moving left and right to contact the contact, due to the structural principle, firstly, it is not easy to implement and control; secondly, it will disrupt the stability of the usage state and / or lead to an increase in the triggering force. This is because when moving left and right, the usage state must be considered firstly. To improve the stability of the operating state, the force of the stabilizing control element needs to be increased. However, increasing the stabilizing force of the control element will lead to an increase in triggering force and a decrease in triggering sensitivity. In this case, the stability of the operating state and the triggering force are inversely proportional. Therefore, balancing these two points is very tricky, resulting in a situation where you can't have your cake and eat it too. However, if you go with the flow and move the lever up and down or forward and backward, the stability of the operating state and the triggering force are separated and will not interfere with each other excessively or be directly related. This allows you to reduce the triggering force as much as possible while ensuring the stability of the operating state, achieving the effect of having your cake and eating it too. Because, at this time, whether the control lever moves up and down or forward and backward, it does not affect the left and right movement of the displacement element 41, and the two are not directly related. Therefore, the optimal displacement position of the control element 21 should be determined according to the movement trajectory of the displacement element 41, especially the movement trajectory during the switching from core delivery to core retraction.

[0401] 52. The deformation slot 713K allows the structure to have a certain deformation resilience. Therefore, it can be added to the core-exit boss 713, positioning member 7, displacement member 41, adjusting member, control member 2, outer rod 1, rotating member 82 and / or rotating abutment boss 413; providing better deformation space and deformation force for the required structure. At the same time, it can reverse the original structure that requires deformation force, so that it does not need deformation force. By adding deformation slot 713K to the corresponding structure that needs to cooperate, it can be made to have deformation force. This method can be better utilized according to different usage structures and internal structure space conditions. As shown in embodiment 16, the displacement member 41 is replaced by the rotating member 82. If the rotating member 82 is used for deformation, deformation space needs to be provided for the rotating member 82. This is not difficult. The main problem is that if the rotating member 82 has deformation capability, it will also be easy for the rotating member 82 to detach from the positioning slot 71, which will lead to the instability of the overall structure and increase many uncertainties. The factors that determine the rotation are: 1) ensuring that the rotating part 82 does not have excessive deformation capacity; 2) using the core boss 713 for deformation, which can better utilize the internal space and also eliminate the worry of the rotating part 82 dislodging from the positioning groove; 3) for component installation, the deformation groove 713K can provide convenience and stability. As shown in Embodiment 15, the rotating locking part 41211 on the rotating fastener 4121 is equipped with a deformation groove 713K, allowing it to be better fitted into the rotating boss 412; 4) providing a larger production tolerance while ensuring practical stability after installation; 5) providing better contact for the component. For example, in Embodiment 8, the clamping part 4131 needs to contact the rotating part 82. If the clamping part 4131 has deformation capacity, it can better contact the rotating part 82. Therefore, by adding a deformation groove 713K near the clamping part 4131 on the rotating fastener 4121, the contact effect of the clamping part 4131 can be greatly improved.

[0402] 53. As can also be seen from Example 8, the matching methods of the rotating part 82 and the rotating boss 412 are also very diverse. It is not limited to the rotating part 82 having a hole to fit onto the rotating boss 412. Alternatively, the rotating part 82 may have a rotating boss 412, and the displacement part 41 may have a rotating through hole 41F. The rotating boss 412 on the rotating part 82 can be used by fitting it into the rotating through hole 41F.
