Description

Technical Field

[0001] This invention relates to the field of pen, specifically a multi-directional control retractor pen. Background Technology

[0002] Currently, most retractable pens on the market use a single control method, such as a press-type retractor. Users need to manually press the pen body to extend or retract the refill. While simple, this method can be inflexible or inconvenient in certain situations, especially when frequent refill switching is required. Furthermore, this single control method limits the product's application scenarios and user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-directional control retractor pen to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A multi-directional control retractable pen includes an inner rod assembly, an outer rod, a pen retractor, and a return spring.

[0005] The inner rod assembly is slidably telescopically sleeved on the inner side of the outer rod, and the return spring is sleeved between the front of the pen refill and the inner side of the inner rod assembly to provide the refill return force.

[0007] The inner side of the top rod is equipped with a trigger receiver, a trigger master control, and a lead feeding / retracting control mechanism; the lead feeding / retracting control mechanism is a switch that switches between lead feeding and retracting states in conjunction with the elastic force of a reset spring; the trigger receiver can move axially under the squeezing pressure of the trigger master control; the trigger master control can guide the direction of gravity to move the trigger receiver according to the pen's usage state.

[0008] A pressing component is fixedly installed on the inner side of the top rod. The trigger control is slidably installed on the pressing component. The relative displacement distance generated by the sliding of the trigger control and the pressing component controls the opening and closing of the core-collecting control mechanism.

[0009] Preferably, the core feeding and receiving control mechanism includes a control rod, a limiting member, and a core feeding guide member; a core feeding and receiving control channel is formed between the limiting member and the core feeding guide member; the control rod is movably installed at the extension end of the inner rod body, and the control head of the control rod is located within the core feeding and receiving control channel; the limiting member can move vertically closer to or further away from the core feeding guide member, and the passage switch of the control rod is opened by the distance from the core feeding guide member; when the distance between the limiting member and the core feeding guide member is too close to allow the limiting member to pass from top to bottom, the core feeding state is maintained; otherwise, core feeding is achieved.

[0010] Preferably, the limiting member is fixedly connected to the middle of the side wall of the trigger receiver, and an elastic member is fixedly connected to the upper end of the trigger receiver to provide vertical movement and reset force.

[0011] Preferably, the upper and lower ends of the trigger receiver are respectively designated as a trigger head and an abutment tail, and the limiting member is fixedly connected to the part of the trigger receiver located between the trigger head and the abutment tail, with the abutment tail located at the upper end of the impact rail.

[0012] Preferably, the upper part of the pressing member is provided with a trigger groove, and the core-out and core-retracting control channel is provided on the side of the lower part of the pressing member facing the control rod. A limit channel is provided between the trigger groove and the core-out and core-retracting control channel. The trigger head is installed in the trigger groove, the limit member slides and is restricted in the limit channel, and the abutting tail is located on the lower side of the bottom end of the pressing member and the inner side of the impact rail.

[0013] Preferably, the triggering main control includes a gravity component, which is movably placed within the impact track, and the gravity component can be located below or above the triggering control.

[0014] Preferably, the trigger control includes a trigger component, which includes a counterweight mounted annularly on the top of the pressing part, a connecting part, a trigger groove, and a corresponding mounting groove on the trigger head. The connecting part is inserted into the mounting groove, an elastic element is sleeved between the trigger head and the trigger groove on the outer periphery of the connecting part, and the counterweight is sleeved between the pressing part and the connecting part on the outer periphery of the connecting part.

[0015] Preferably, the trigger control includes a trigger component, which includes a ringless main component and a ringless groove formed on the top of the pressing component for mounting the ringless main component. A plug is fixedly installed at the top of the ringless groove. An impact component is movably arranged between the plug and the ringless main component. A connecting groove is correspondingly formed on the trigger groove and the trigger head. The lower end of the ringless main component is inserted into the connecting groove. An elastic component is sleeved between the ringless main component and the trigger head on the outside of the ringless main component. A small spring is fixedly connected between the trigger head and the trigger groove.

[0016] Preferably, the trigger main control includes a trigger acyclic assembly, which includes a counterweight mounted annularly on the top of the pressing component, a acyclic main component, and an acyclic groove formed on the top of the pressing component for mounting the acyclic main component. A plug is provided at the top of the acyclic groove. The plug and the acyclic groove are inserted and fixed to form several through grooves. Insert blocks are evenly distributed on the inner wall of the counterweight and are inserted into the through grooves.

[0017] Preferably, the plug and the annular groove wall are fixed by a number of insert plates inserted at intervals, and if the length of the insert plate of the annular groove wall is greater than the length of the insert plate at the lower end of the plug, a through groove is created between adjacent insert plates; or the plug and the annular groove wall are fixed by a number of slots and insert plates inserted, and if the length of the insert plate is greater than the length of the slot, a through groove is created between adjacent insert plates.

[0018] Preferably, the plug has a through hole in the middle and an auxiliary impact component is placed therein.

[0019] Preferably, elastic pressing blocks are provided on the outer wall of the front part of the inner rod body and at corresponding positions on the front part of the outer rod. The surface of the elastic pressing block on the outer wall of the inner rod body is provided with a guide step that contacts the elastic pressing block on the outer rod, so that when the outer elastic pressing block is pressed, the inner elastic pressing block can be driven to move through the inclined surface of the guide step.

[0020] Preferably, the inner rod body is composed of a front rod and a core rod that are slidably connected, and the front rod has a guide arc on the side away from the return spring. A guide block is provided on the core rod at the guide line. The inner wall of the outer rod has a limiting step, and the limiting step is in contact with the upper end of the front rod. When the front rod is rotated, the guide arc can press the guide block away from the return spring.

[0021] Preferably, a limiting structure is provided between the inner rod body and the top rod to restrict them to slide relative to each other only along a fixed distance and not to rotate relative to each other.

[0022] Preferably, the limiting structure includes at least one set of outer wall hooks and limiting grooves respectively disposed on the side wall of the inner rod assembly or the outer rod. The outer wall hooks are hooked into the limiting grooves so that the inner rod assembly and the outer rod can maintain relative sliding for a certain distance, making them less likely to rotate relative to each other and less likely to separate.

[0023] Preferably, the limiting structure includes at least one set of vertical grooves and bosses respectively provided on the inner rod body or the outer rod sidewall. The matching sliding connection of the bosses and vertical grooves enables the inner rod body and the outer rod to maintain relative sliding distance, making them less prone to relative rotation and separation.

[0024] Preferably, the inner rod body consists of a front rod and a core rod that are fixed in a detachable manner.

[0025] Standard procedure: The outer rod, top rod, and inner rod bodies, as well as the core-exit and retraction control mechanisms between them, need to be maintained and implemented: When the operator holds the outer rod and moves the top rod downward, the outer rod and the inner rod remain relatively stationary. The top rod drives the internal pen refill to move, and the pen refill control mechanism maintains the pen refill state.

[0026] When the operator holds the outer rod and simultaneously moves the inner rod body upward, the top rod, outer rod, and pen refill remain relatively stationary, while the inner rod body and outer rod are relatively compressed. The pen refill control mechanism causes the lower end of the pen refill to extend out and remain in the extended state.

[0027] Advanced operations: By utilizing the principles of gravity or triggering, the displacement of the triggered control can be directly or indirectly affected, thereby achieving automatic core retraction through gravity or triggering.

[0028] Specifically, this can be achieved through methods such as swinging, vibration, inversion, placement, and external impact.

[0029] Compared with the prior art, the beneficial effects of the present invention are: 1. It offers multiple control methods, including pull-out / press-out refills, and additional refill via gravity or trigger. Pulling represents bottom-up control, pressing represents top-down control, triggering represents all-around control, and gravity represents inside-out control. Users can choose the appropriate operation method based on their habits and scenarios. When quickly switching refill states is needed, gravity or impact can be used instead of manual pressing, improving convenience and efficiency.

[0030] 2. By coordinating the main trigger control and the triggered controlled control, the refill and ejection processes are automated. Users only need to perform simple actions, such as flicking the pen or pressing the pen body, to control the refill, reducing the tedium of manual operation.

[0031] 3. Through the ingenious cooperation of components such as the inner rod assembly, outer rod, trigger receiver, and trigger master controller, a clever control function is achieved. Furthermore, the various components are rationally arranged within a limited space, resulting in a compact and stable pen body.

[0032] 4. This invention is highly innovative. Its core lies in adding a third-party reference system—the outer rod—to solve the problem of simultaneously performing lifting and pressing operations at the lowest cost. It also cleverly integrates the main trigger control and the triggered controlled control, allowing for the addition of advanced trigger-based core winding and / or gravity-based core winding on the original basis. With the simplest approach, it achieves outstanding substantive features and significant progress, greatly enriching people's core winding selection methods and experience, and providing people with a more comprehensive range of choices.

[0033] 5. A return spring can be added between the upper rod and the outer rod, or between the lower rod and the outer rod, or the outer rod can be restrained to a certain extent by using the pen clip to prevent the outer rod from wobbling up and down when the core is ejected, thus making the product more robust.

[0034] 6. The essence of this invention is to completely open up the channels for the lower lever to move up and retract the core, and the upper lever to move down and retract the core. Compared with traditional pens, only one necessary component is added to achieve complete functionality. Moreover, this functionality is responsive; that is, the operation of moving the lower lever up to move the core can be reversed by moving the upper lever down. Both use a single system to switch between core locking and core retraction, allowing for seamless operation. In contrast, the bidirectional press-and-retract pen disclosed in the prior art document CN201910651869.5 achieves the same effect by using two sets of core locking structures, one upper and one lower. Even if the two sets of core locking structures use the same principle, they cannot achieve true connection and interaction. Although both sets of core locking structures can achieve a relatively self-locking effect when the core is retracted, making it easy to carry, the logic is not simple enough. If consumers do not pay attention to the previous operation status, they may make mistakes, thereby reducing the user experience. Furthermore, the component and manufacturing requirements brought about by the two sets of core locking structures are relatively more complex.

[0035] 7. More diverse operation methods can be achieved by adding third-party accessories or components. For example, the upper lever can be equipped with a pen clip or the outer lever can be slotted to add side operation parts that can be detachably installed inside the outer lever, thereby increasing the possibility of side sliding operation, side pressing operation, rotation operation and / or side linkage of the upper part of the pen; while the lower lever can be equipped with side pressing parts and rotating parts to increase the operation of the lower part of the pen, such as: side sliding or pressing to extend the lead, side sliding or pressing to retract the lead, pinching to extend the lead, pinching to retract the lead, rotating to extend the lead and / or rotating to retract the lead.

[0036] 8. While there is linkage, they are also independent of each other. Point 6 above describes the linkage between the release and retraction of the core brought about by the main lowering or raising of the lever in this invention. That is, while there is linkage, the external operational experience presented by the upper and lower levers is independent of each other. For example, when raising the lever, the lower lever and the outer lever can be considered as a relatively whole; and when lowering the lever, the upper lever and the outer lever can also be considered as a relatively whole. This means the external operational experience is independent. The lifting, pressing, side sliding, side pressing, rotating, and side linkage experiences provided to consumers are all extremely complete and relatively independent. The operational independence between the lifting and pressing experiences is particularly good. From an experiential perspective, it is excellent. It can maintain the traditional complete experience while simultaneously allowing them to coexist, and also achieving a linkage effect between core release locking and core retraction.

[0075] Please see Figures 1-28 This invention provides a multi-directional control retractable pen technology solution: A multi-directional control pen for retracting the lead includes an inner rod assembly 1, an outer rod 2, a lead 3, and a return spring 4. The inner rod assembly 1 is slidably and telescopically sleeved inside the outer rod 2. The return spring 4 is sleeved between the front part of the lead 3 and the inner side of the inner rod assembly 1 to provide a retracting force. The inner rod assembly 1 is composed of a front rod 1a, a core rod 1b, and a top rod 1c. The front rod 1a and the core rod 1b together form the main body of the inner rod. Elastic outer wall hooks 71 are fixedly provided on both sides of the outer wall of the core rod 1b and the top rod 1c, and the two outer wall hooks 71 are distributed along the axial direction of the inner rod assembly 1. Limiting grooves 72 are formed on both sides of the inner wall of the outer rod 2. The outer wall hooks 71 can elastically deform under internal pressure and then be inserted into the limiting grooves 72 for sliding restriction. The cooperation between the inner rod assembly 1 and the limiting groove 72 allows the inner rod assembly 1 and the outer rod 2 to maintain relative sliding distance, making them less prone to relative rotation and separation. The outer wall hook 71 extends a vertical groove 710 near the front rod 1a. The outer rod 2 has a boss 720 corresponding to the vertical groove 710. The boss 720 and the vertical groove 710 are matched and slidably connected for further anti-rotation limiting. The lower end of the top rod 1c extends into the core rod 1b and abuts against the tail end of the pen refill 3. The upper end of the core rod 1b extends into the top rod 1c and is slidably connected to it. The lower extension end 1c0 of the top rod 1c and the upper extension end 1b0 of the core rod 1b are staggered. An impact rail Q is vertically provided in the middle of the extension end 1c0. The extension ends 1c0 can be set as a pair.

[0076] The dual-control retractable pen also includes a pressing component 6. The top of the core rod 1b is provided with a mounting groove 11, and a control rod 1-0 is movably connected through the mounting groove 11. The pressing component 6 is installed on the top of the top rod 1c, and the top rod 1c is fixedly installed with the pressing component 6. The upper part of the pressing component 6 is provided with a trigger groove 61, and the lower part facing the control rod 1-0 is provided with a retractable control channel 62. The control head end of the control rod 1-0 is restricted to move only along the retractable control channel 63. A limit channel 63 is provided between the trigger groove 61 and the retractable control channel 62. A retractable guide component 6-0 is fixedly provided in the retractable control channel 62. The retractable guide component 6-0 is divided into an upper guide platform 6-01 and a lower guide platform 6-02.

[0077] The dual-control retracting pen also includes a trigger receiver 5, which is installed at the top of the top rod 1c. The upper and lower ends of the trigger receiver 5 are respectively set as a trigger head 51 and an abutment tail 52. An elastic element 53 is fixedly connected to the upper end of the trigger receiver 5. The elastic element 53 can be an elastic material such as a spring. When the trigger head 51 is placed in the trigger groove 61, the elastic element 53 elastically presses against the top wall of the trigger groove 61. A limit element 5-0 is fixedly connected to the side wall of the trigger receiver 5 facing the control rod 1-0, located between the trigger head 51 and the abutment tail 52. The limit element 5-0 slides within the limit channel 63, and the extension and retraction of the elastic element 53 can control the limit element 5-0 to move up and down along the limit channel 63, thereby cooperating with the core guide 6-0 to form a control head end access switch. The abutment tail 52 is located below the pressing member 6 and leaves a gap with the bottom end of the pressing member 6. The abutment tail 52 extends into the upper part of the impact rail Q.

[0078] The aforementioned control lever 1-0, limit member 5-0, and core guide member 6-0 constitute the core feeding and receiving control mechanism.

[0079] The trigger control 8 is installed inside the top rod 1c. The trigger control 8 can guide the direction of gravity to move the trigger control 5 according to the pen's usage status.

[0080] When performing the core-pulling or core-retracting action, keep the outer rod 2 stationary and control the front rod 1a and core rod 1b to move upward. Then, the top rod 1c is affected by the cooperation of the outer wall hook 71 and the limiting groove 72 and cannot continue to move upward. It is also stationary relative to the outer rod 2. At this time, the outer rod 2 and the top rod 1c are regarded as a whole.

[0081] When pressing out or pressing back the core, keep the outer rod 2 still and control the top rod 1c to move down. Then, the front rod 1a and the core rod 1b are affected by the cooperation of the outer wall hook 71 and the limiting groove 72 and cannot continue to move down. They are also stationary relative to the outer rod 2. At this time, the outer rod 2, the front rod 1a and the core rod 1b are regarded as a whole. Example 1

[0082] Please see Figures 1-10 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger control 8 is a gravity component 81, which is movably set inside the impact rail Q and located on the lower side of the abutment tail 52. In this example, the gravity component 81 is spherical.

[0083] When retracting the lead, hold the front lever 1a and swing the pen out horizontally or upside down. The gravity component 81 moves away from the lead 3 in the impact track Q and impacts the tail 52. Due to the gap, the trigger control 5 first moves upward to squeeze the elastic component 53. Then the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lead guide component 6-0. This opens the control head switch. The head of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the elastic force of the return spring 4, the push rod 1c moves away from the front lever 1a and the lead rod 1b. The push rod 1c reaches the maximum distance away from the front lever 1a through the cooperation of its outer wall hook 71 and the limiting groove 72, thus realizing the retraction of the lead.

[0084] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will move downwards under the force of the return spring 4 to achieve core retrieval.

[0085] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0086] When the core is ejected, hold the outer rod 2 and pull the front rod 1a up. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0087] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 2

[0088] Please see Figures 11-12 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger control 8 includes a gravity component 81 and a trigger assembly 82. The gravity component 81 is movably disposed inside the impact rail Q and is located on the lower side of the abutting tail 52. In this example, the gravity component 81 is spherical.

[0089] The trigger assembly 82 includes a counterweight 821 annularly mounted on the top of the pressing member 6, a connecting part 822, and a corresponding mounting groove 820 on the upper top wall of the trigger groove 61 and the top of the trigger head 51. The connecting part 822 is inserted into the mounting groove 820 and a gap is left between its bottom end and the trigger head 51. The elastic member 53 is sleeved between the trigger head 51 and the upper top wall of the trigger groove 61 on the outer periphery of the connecting part 822. The counterweight 821 is sleeved between the pressing member 6 on the outer periphery of the connecting part 822 and the top of the connecting part 822. The side of the pressing member 6 and the top of the connecting part 822 that is close to the counterweight 821 is set with an angle to prevent the counterweight 821 from falling off after being sleeved.

[0090] When retracting the pen, hold the front lever 1a and swing the pen out horizontally or upside down. The gravity component 81 moves away from the pen core 3 within the impact track Q, impacting and abutting the tail 52. Due to the gap, the trigger control 5 first moves upward, squeezing the elastic component 53. Then, the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front lever 1a and the core rod 1b. The push rod 1c reaches the maximum distance away from the front lever 1a through the cooperation of its outer wall hook 71 and the limiting groove 72. Thus, the pen is retracted.

[0091] Alternatively, when the counterweight 821 hits the table, the impact force of the counterweight 821 can cause the connecting part 822 to move away from the pen refill 3, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. Then, the limit element 5-0 moves upward as described above, thus controlling the head switch to open. By adding the trigger component 82, the triggering effect is improved, thereby achieving the refill state.

[0092] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0093] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will move downwards under the force of the return spring 4 to achieve core retrieval.

[0094] When the core is ejected, hold the outer rod 2 and pull the front rod 1a up. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0095] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 3

[0096] Please see Figures 13-14 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger control 8 is a trigger assembly 82, which includes a counterweight 821 annularly mounted on the top of the pressing member 6, a connecting part 822, an upper top wall of the trigger groove 61 and a corresponding mounting groove 820 on the top of the trigger head 51, the connecting part 822 being inserted into the mounting groove 820 and leaving a gap between its bottom end and the trigger head 51, the elastic member 53 being sleeved between the trigger head 51 and the upper top wall of the trigger groove 61 on the outer periphery of the connecting part 822, the counterweight 821 being sleeved between the pressing member 6 and the top of the connecting part 822 on the outer periphery of the connecting part 822, and the side of the pressing member 6 and the top of the connecting part 822 near the counterweight 821 being set at an angle to prevent the counterweight 821 from falling off after being sleeved.

[0097] When retracting the core, the pen is placed on the table. When the counterweight 821 impacts the table, the impact force causes the connecting part 822 to move outward, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. The limiting element 5-0 then moves upward along the limiting channel 63, increasing the distance between it and the lower guide platform 6-02, thus opening the control head switch. Under the elastic force of the return spring 4, the head end of the control rod 1-0 can pass over the limiting element 5-0. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front rod 1a and the core rod 1b. The push rod 1c, through its outer wall hook 71 and the limiting groove 72, reaches its maximum distance away from the front rod 1a, thus achieving core retraction.

[0098] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0099] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will be retrieved by moving downwards under the force of the reset spring 4.

[0100] When the core is ejected, hold the outer rod 2 and pull the front rod 1a upwards. At the same time, the counterweight 821 presses down the top rod 1c, so that the head of the control rod 1-0 moves upwards past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0101] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 4

[0102] Please see Figures 15-17 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger main control 8 includes a gravity component 81 and a ringless component 83. The gravity component 81 is movably disposed inside the impact rail Q and is located on the lower side of the abutting tail 52. In this example, the gravity component 81 is spherical.

[0103] The ringless assembly 83 includes a ringless main component 831 and a ringless groove 830 formed on the top of the pressing component 6 for mounting the ringless main component 831. A plug 832 is fixedly installed at the top of the ringless groove 830. An impact component 833 is movably arranged between the plug 832 and the ringless main component 831. In this example, the impact component 833 is spherical. A connecting groove is formed on the upper top wall of the trigger groove 61 and the trigger head 51. The lower end of the ringless main component 831 is inserted and fixed in the connecting groove. An elastic component 53 is sleeved between the ringless main component 831 and the upper top wall of the trigger head 51 on the outside of the ringless main component 831. A small spring 834 is fixedly connected between the trigger head 51 and the lower bottom wall of the trigger groove 61.

[0104] When retracting the core, hold the front lever 1a and invert the pen. The gravity component 81 moves away from the pen core 3 within the impact track Q and impacts the tail 52. Due to the gap, the trigger control 5 first moves upward to squeeze the elastic component 53. Then the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the elastic force of the return spring 4, the push rod 1c moves away from the front lever 1a and the core rod 1b, and the push rod 1c pulls the outer rod 2 upward through its outer wall hook 71 to achieve core retraction.

[0105] Alternatively, the pen can be thrown out and placed horizontally. The impact component 833 will move in all directions under the influence of gravity and / or external forces, causing the ringless main component 831 to move downward, which will drive the trigger control component 5 to move downward. This will cause the limiting component 5-0 to move downward along the limiting channel 63, reducing the distance with the lower guide platform 6-02. This will allow the restriction at the head of the control lever 1-0 to be opened, and the head of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the reset spring 4 to achieve core retraction.

[0106] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0107] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will be retrieved by moving downwards under the force of the reset spring 4.

[0108] When the core is ejected, hold the outer rod 2 and pull the front rod 1a up. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0109] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 5

[0110] Please see Figure 18-21 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger main control 8 includes a trigger ringless assembly 84, which includes a counterweight 821 ring-mounted on the top of the pressing part 6, a ringless main part 831, and a ringless groove 830 opened on the top of the pressing part 6 for the ringless main part 831 to be installed. The top of the ringless groove 830 is provided with a plug 832, and the plug 832 and the groove wall of the ringless groove 830 are fixed by several slots and insert plates. If the length of the insert plate is greater than that of the slot, a through groove 841 is generated between adjacent insert plates. Insert blocks 8210 are evenly distributed on the inner wall of the counterweight 821. The insert blocks 8210 are inserted into the through groove 841 and built into the top upper side of the ringless main part 831. The side of the insert block 8210 away from the plug 832 is a slope, so that the counterweight 821 will not fall off after being sleeved.

[0111] An impact member 833 is movably disposed between the plug 832 and the ringless main component 831. In this example, the impact member 833 is spherical. A through hole is opened in the middle of the plug 832 and a spherical auxiliary impact member 835 is placed therein. The upper top wall of the trigger groove 61 and the trigger head 51 are respectively provided with connecting grooves. The lower end of the ringless main component 831 passes through the connecting groove. The elastic member 53 is sleeved between the lower end of the trigger head 51 on the outside of the ringless main component 831 and the lower bottom wall of the trigger groove 61.

[0112] When the pen is retracted, the pen is thrown out and placed horizontally. The impactor 833 moves in all directions under the influence of gravity and / or external force, causing the ringless main component 831 to move downward, which in turn causes the triggering control 5 to move downward. This causes the limiting component 5-0 to move downward along the limiting channel 63, reducing the distance with the lower guide platform 6-02. This allows the restriction at the head of the control lever 1-0 to be released. Under the elastic force of the return spring 4, the head of the control lever 1-0 can pass over the limiting component 5-0 to retract the pen. At the same time, under the action of external force, the auxiliary impactor 835 impacts the impactor 833, making the effect of the impactor 833's movement triggering better.

[0113] When retracting the core, the pen is placed on the table. When the counterweight 821 impacts the table, the impact force causes the connecting part 822 to move outward, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. The limiting element 5-0 then moves upward along the limiting channel 63, increasing the distance between it and the lower guide platform 6-02, thus opening the control head switch. Under the elastic force of the return spring 4, the head end of the control rod 1-0 can pass over the limiting element 5-0. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front rod 1a and the core rod 1b. The push rod 1c, through its outer wall hook 71 and the limiting groove 72, reaches its maximum distance away from the front rod 1a, thus achieving core retraction.

[0114] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will move downwards under the force of the return spring 4 to achieve core retrieval.

[0115] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0116] When the core is ejected, hold the outer rod 2 and pull the front rod 1a up. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0117] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 6

[0118] Please see Figure 22-24 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are threaded together; the trigger control 8 includes a gravity component 81, a trigger assembly 82 and a ringless assembly 83. The gravity component 81 is movably set inside the impact rail Q. In this example, the gravity component 81 is spherical.

[0119] The trigger main control 8 includes a gravity component 81 and a trigger ringless assembly 84. The gravity component 81 is movably disposed inside the impact track Q and is located on the lower side of the abutment tail 52. In this example, the gravity component 81 is spherical.

[0120] The triggering ringless assembly 84 includes a counterweight 821 ring-mounted on the top of the pressing member 6, a ringless main member 831, and a ringless groove 830 opened on the top of the pressing member 6 for mounting the ringless main member 831. The top of the ringless groove 830 is provided with a plug 832, and the plug 832 and the groove wall of the ringless groove 830 are fixed by several insert plates inserted at intervals. If the length of the insert plate on the groove wall of the ringless groove 830 is greater than the length of the insert plate at the lower end of the plug 832, a through groove 841 is generated between adjacent insert plates. Insert blocks 8210 are evenly distributed on the inner wall of the counterweight 821. The insert blocks 8210 are inserted into the through groove 841 and built into the lower side of the top of the ringless main member 831. The side of the insert block 8210 near the plug 832 is inclined to prevent the counterweight 821 from falling off after being fitted.

[0121] An impact member 833 is movably disposed between the plug 832 and the ringless main component 831. In this example, the impact member 833 is spherical. The upper top wall of the trigger groove 61 and the trigger head 51 are respectively provided with connecting grooves. The lower end of the ringless main component 831 passes through the connecting groove. The elastic member 53 is sleeved between the upper end of the trigger head 51 on the outside of the ringless main component 831 and the upper bottom wall of the trigger groove 61. A small spring 834 is fixedly connected between the trigger head 51 and the lower bottom wall of the trigger groove 61.

[0122] The plug 832 and the ringless main component 831 are also provided with an impact trigger slope.

[0123] The following are at least some of the following methods for core recovery: 1. When the pen is inverted, the gravity component 81 moves away from the pen refill 3 within the impact track Q and impacts the tail 52. Due to the gap, the trigger receiver 5 first moves upward to squeeze the elastic component 53. Then, the limit component 5-0 moves upward along the limit channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control rod 1-0 can pass over the limit component 5-0 under the elastic force of the return spring 4. Due to the elastic force of the return spring 4, the push rod 1c moves away from the front rod 1a and the core rod 1b. The push rod 1c pulls the outer rod 2 upward through its outer wall hook 71 to achieve core retraction. At the same time, when the counterweight 821 hits the table, the impact force of the counterweight 821 can cause the connecting part 822 to move away from the pen refill 3, thereby squeezing the elastic component 53 and pulling the trigger receiver 5 upward, ultimately causing the limit component 5-0 to move upward, thus achieving core retraction under the elastic force of the return spring 4.

[0124] 2. Hold the front lever 1a and swing the pen horizontally. At the same time, the impact component 833 impacts the stopper 832 and / or the impact trigger slope of the ringless main component 831 in all directions. This forces the ringless main component 831 to move down. This causes the trigger control 5 to move down, which in turn causes the limit component 5-0 to move down, thereby achieving the core retraction under the elastic force of the reset spring 4.

[0125] 3. Manually hold the outer rod 2 and pull down the front rod 1a, so that the head of the control rod 1-0 moves down past the limit piece 5-0 and the lower guide plate 6-02, and the core is retracted under the elastic force of the reset spring 4.

[0126] When the core is ejected, hold the outer rod 2 and pull the front rod 1a up. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide table 6-02 to achieve core ejection. After releasing the hand, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection. Example 7

[0127] Please see Figure 25 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are an integral structure; the trigger control 8 includes a gravity component 81 and a trigger assembly 82. The gravity component 81 is movably disposed inside the impact rail Q and is located on the lower side of the abutting tail 52. In this example, the gravity component 81 is spherical.

[0128] The trigger assembly 82 includes a counterweight 821 annularly mounted on the top of the pressing member 6, a connecting part 822, and a corresponding mounting groove 820 on the upper top wall of the trigger groove 61 and the top of the trigger head 51. The connecting part 822 is inserted into the mounting groove 820, with a gap between its bottom end and the trigger head 51. An elastic member 53 is sleeved between the trigger head 51 and the trigger groove 61 on the outer periphery of the connecting part 822. The counterweight 821 is also sleeved between the pressing member 6 on the outer periphery of the connecting part 822 and the top of the connecting part 822, and is pressed... The top of component 6 and the connecting part 822 near the counterweight 821 is set with an inclined surface to prevent the counterweight 821 from falling off after being fitted. The counterweight 821, the connecting part 822, the upper top wall of the trigger groove 61 and the top of the trigger head 51 are provided with corresponding mounting grooves 820. The connecting part 822 is inserted into the mounting groove 820 and a gap is left between its bottom end and the trigger head 51. The elastic element 53 is fitted between the connecting part 822 and the trigger groove 61, and the counterweight 821 is also fitted on the outside of the connecting part 822.

[0129] Elastic pressing blocks 91 are provided on the outer wall of the front part of the inner rod body and at the corresponding position of the front part of the outer rod 2. The surface of the elastic pressing block 91 on the outer wall of the inner rod body is provided with a guide step that contacts the elastic pressing block 91 on the outer rod 2. This allows the inner elastic pressing block 91 to move through the inclined surface of the guide step when the outer elastic pressing block 91 is pressed, thereby enabling the inner rod body to move relative to the outer rod 2.

[0130] When retracting the pen, hold the front lever 1a and swing the pen out horizontally or upside down. The gravity component 81 moves away from the pen core 3 within the impact track Q, impacting and abutting the tail 52. Due to the gap, the trigger control 5 first moves upward, squeezing the elastic component 53. Then, the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front lever 1a and the core rod 1b. The push rod 1c reaches the maximum distance away from the front lever 1a through the cooperation of its outer wall hook 71 and the limiting groove 72. Thus, the pen is retracted.

[0131] Alternatively, when the counterweight 821 hits the table, the impact force of the counterweight 821 can cause the connecting part 822 to move away from the pen refill 3, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. Then, the limit element 5-0 moves upward as described above, thus controlling the head switch to open. By adding the trigger component 82, the triggering effect is improved, thereby achieving the refill state.

[0132] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0133] Alternatively, one can manually grasp the outer rod 2 and pull the front rod 1a upwards. Guided by the upper guide plate 6-01, the head of the control rod 1-0 will pass the limit of the limit piece 5-0 and the lower guide plate 6-02, reaching the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing the hand, the core will move downwards under the force of the return spring 4 to achieve core retrieval.

[0134] When ejecting the core, hold the outer rod 2 and pull the inner rod body upward or press the elastic pressing block 91 on the outside to make the inner rod body displace relative to the outer rod 2. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide platform 6-02 to achieve core ejection. After releasing, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide platform 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0135] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 8

[0136] Please see Figure 26 This invention provides a multi-directional control retractable pen technology solution: The front rod 1a and the core rod 1b are an integral structure; the trigger control 8 includes a gravity component 81 and a trigger assembly 82. The gravity component 81 is movably disposed inside the impact rail Q and is located on the lower side of the abutting tail 52. In this example, the gravity component 81 is spherical.

[0137] The trigger assembly 82 includes a counterweight 821 annularly mounted on the top of the pressing member 6, a connecting part 822, and a corresponding mounting groove 820 on the upper top wall of the trigger groove 61 and the top of the trigger head 51. The connecting part 822 is inserted into the mounting groove 820, with a gap between its bottom end and the trigger head 51. An elastic member 53 is sleeved between the trigger head 51 and the trigger groove 61 on the outer periphery of the connecting part 822. The counterweight 821 is also sleeved between the pressing member 6 on the outer periphery of the connecting part 822 and the top of the connecting part 822, and is pressed... The top of component 6 and the connecting part 822 near the counterweight 821 is set with a slope to prevent the counterweight 821 from falling off after being fitted. The counterweight 821 and the connecting part 822 at the top of the pressing component 6, the upper top wall of the trigger groove 61 and the top of the trigger head 51 are provided with corresponding mounting grooves 820. The connecting part 822 is inserted into the mounting groove 820 and a gap is left between its bottom end and the trigger head 51. The elastic element 53 is fitted between the connecting part 822 and the trigger groove 61, and the counterweight 821 is also fitted on the outside of the connecting part 822.

[0138] Multiple elastic pressing blocks 91 are evenly provided circumferentially on the outer wall of the inner rod body and the corresponding position of the front of the outer rod 2. The surface of the elastic pressing block 91 located on the outer wall of the inner rod body has a guide step that contacts the elastic pressing block 91 on the outer rod 2. This allows the inner elastic pressing block 91 to move through the inclined surface of the guide step when the outer elastic pressing block 91 is pressed, thereby realizing the movement of the inner rod body relative to the outer rod 2.

[0139] When retracting the pen, hold the front lever 1a and swing the pen out horizontally or upside down. The gravity component 81 moves away from the pen core 3 within the impact track Q, impacting and abutting the tail 52. Due to the gap, the trigger control 5 first moves upward, squeezing the elastic component 53. Then, the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front lever 1a and the core rod 1b. The push rod 1c reaches the maximum distance away from the front lever 1a through the cooperation of its outer wall hook 71 and the limiting groove 72. Thus, the pen is retracted.

[0140] Alternatively, when the counterweight 821 hits the table, the impact force of the counterweight 821 can cause the connecting part 822 to move away from the pen refill 3, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. Then, the limit element 5-0 moves upward as described above, thus controlling the head switch to open. By adding the trigger component 82, the triggering effect is improved, thereby achieving the refill state.

[0141] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0142] Manually grasp the outer rod 2 and pull up the inner rod body or squeeze the elastic pressing block 91 on the outside to make the inner rod body displace relative to the outer rod 2. Guided by the upper guide platform 6-01, the head of the control rod 1-0 passes the limit of the limit piece 5-0 and the lower guide platform 6-02 and reaches the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing, it moves down under the force of the return spring 4 to achieve core-retrieving.

[0143] When ejecting the core, hold the outer rod 2 and pull the inner rod body upward or squeeze the elastic pressing block 91 on the outside to make the inner rod body displace relative to the outer rod 2. At the same time, the gravity member 81 presses down the top rod 1c, so that the head of the control rod 1-0 moves upward past the limit member 5-0 and the lower guide platform 6-02 to achieve core ejection. After releasing, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide platform 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0144] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection. Example 9

[0145] Please see Figures 27-28 This invention provides a multi-directional control retractable pen technology solution: The trigger control 8 includes a gravity component 81 and a trigger assembly 82. The gravity component 81 is movably disposed inside the impact track Q and is located on the lower side of the abutment tail 52. In this example, the gravity component 81 is spherical.

[0146] The trigger assembly 82 includes a counterweight 821 annularly mounted on the top of the pressing member 6, a connecting part 822, and a corresponding mounting groove 820 on the upper top wall of the trigger groove 61 and the top of the trigger head 51. The connecting part 822 is inserted into the mounting groove 820, with a gap between its bottom end and the trigger head 51. An elastic member 53 is sleeved between the trigger head 51 and the trigger groove 61 on the outer periphery of the connecting part 822. The counterweight 821 is also sleeved between the pressing member 6 on the outer periphery of the connecting part 822 and the top of the connecting part 822, and is pressed... The top of component 6 and the connecting part 822 near the counterweight 821 is set with an inclined surface to prevent the counterweight 821 from falling off after being fitted. The counterweight 821, the connecting part 822, the upper top wall of the trigger groove 61 and the top of the trigger head 51 are provided with corresponding mounting grooves 820. The connecting part 822 is inserted into the mounting groove 820 and a gap is left between its bottom end and the trigger head 51. The elastic element 53 is fitted between the connecting part 822 and the trigger groove 61, and the counterweight 821 is also fitted on the outside of the connecting part 822.

[0147] The front rod 1a and the core rod 1b of the inner rod body are slidably connected. The front rod 1a has a guide arc 92 on the side away from the return spring 4. The core rod 1b has a guide block 93 at the guide line. The inner wall of the outer rod 2 has a limiting step, and the limiting step is in contact with the upper end of the front rod 1a. When the front rod 1a is rotated, the guide arc 92 can press the guide block 93 away from the return spring 4, and the core rod 1b moves upward relative to the outer rod 2, exposing the front end of the pen lead 3 to achieve lead ejection.

[0148] When retracting the pen, hold the front lever 1a and swing the pen out horizontally or upside down. The gravity component 81 moves away from the pen core 3 within the impact track Q, impacting and abutting the tail 52. Due to the gap, the trigger control 5 first moves upward, squeezing the elastic component 53. Then, the limiting component 5-0 moves upward along the limiting channel 63, increasing the distance with the lower guide platform 6-02, thus opening the control head switch. The head end of the control lever 1-0 can pass over the limiting component 5-0 under the elastic force of the return spring 4. Due to the pushing action of the return spring 4, the push rod 1c moves away from the front lever 1a and the core rod 1b. The push rod 1c reaches the maximum distance away from the front lever 1a through the cooperation of its outer wall hook 71 and the limiting groove 72. Thus, the pen is retracted.

[0149] Alternatively, when the counterweight 821 hits the table, the impact force of the counterweight 821 can cause the connecting part 822 to move away from the pen refill 3, thereby squeezing the elastic element 53 and pulling the trigger control 5 upward. Then, the limit element 5-0 moves upward as described above, thus controlling the head switch to open. By adding the trigger component 82, the triggering effect is improved, thereby achieving the refill state.

[0150] Alternatively, by manually holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 can be moved down together, so that the control rod 1-0, guided by the upper guide plate 6-01, passes over the limit part 5-0 and the lower guide plate 6-02 and reaches the core-retracting area on the left side of the core-retracting control channel 62. After releasing the hand, the core-retracting state is achieved under the action of the return spring 4.

[0151] Manually grasp the outer rod 2 and pull up the inner rod body or squeeze the elastic pressing block 91 on the outside to make the inner rod body displace relative to the outer rod 2. Guided by the upper guide platform 6-01, the head of the control rod 1-0 passes the limit of the limit piece 5-0 and the lower guide platform 6-02 and reaches the core-retrieving area on the left side of the core-retrieving control channel 62. After releasing, it moves down under the force of the return spring 4 to achieve core-retrieving.

[0152] When the core is ejected, pulling up the inner rod body or rotating the front rod 1a presses the guide block 93 away from the reset spring 4 through the guide arc 92, causing the core rod 1b to move upward relative to the outer rod 2. At the same time, the gravity member 81 presses down the top rod 1c, thereby causing the head of the control rod 1-0 to move upward past the limit member 5-0 and the lower guide platform 6-02 to achieve core ejection. After releasing, under the action of the elastic member 53, the distance between the limit member 5-0 and the lower guide platform 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0153] Alternatively, by holding the outer rod 2 and pressing the pressing part 6, the top rod 1c and the receiving part 5 are indirectly controlled to move downward together, so that the control rod 1-0 reaches the cooperation restriction area of ​​the limiting part 5-0 and the lower guide table 6-02 under the guidance of the lower guide table 6-02. Under the action of the elastic part 53, the distance between the limiting part 5-0 and the lower guide table 6-02 is too close to allow the head of the control rod 1-0 to pass through, thus maintaining the core ejection.

[0154] In the above embodiments 1-9, the pen's lead ejection method has at least the following three: 1. Pulling out the core: By keeping the outer rod 2 stationary, pull the front rod 1a and the core rod 1b upwards, so that the control rod 1-0 moves upwards to the upper end of the lower guide table 6-02. At this time, after releasing the hand, under the action of the elastic element 53 and the return spring 4, the distance between the limiting element 5-0 and the lower guide table 6-02 is very close and not enough for the head of the control rod 1-0 to pass through, thus keeping the core out.

[0155] 2. Pressing out the core: By keeping the outer rod 2 stationary, the top rod 1c is directly or indirectly controlled to move downward, so that the lower guide plate 6-02 moves down to the lower end of the control rod 1-0. At this time, after releasing the hand, under the action of the elastic element 53 and the return spring 4, the distance between the limiting element 5-0 and the lower guide plate 6-02 is very close and not enough for the head of the control rod 1-0 to pass through, thus maintaining the core ejection.

[0156] 3. Double-ended core ejection: This causes the control rod 1c and the front rod 1a to move closer together, and the lower guide plate 6-02 and the control rod 1-0 to move closer together, until the control rod 1-0 is located at the upper end of the lower guide plate 6-02. At this point, after releasing the handle, under the action of the elastic element 53 and the return spring 4, the distance between the limiting element 5-0 and the lower guide plate 6-02 is very close and not enough for the head of the control rod 1-0 to pass through, thus maintaining core ejection.

[0157] 4. Pressing out the core: By pressing the elastic pressing block 91 on the outer wall of the inner rod body, the inclined surface of the guide step drives the inner elastic pressing block 91 to move, which indirectly causes the outer rod 2 to move, thereby causing the control rod 1-0 to move to the upper end of the lower guide table 6-02, thus realizing pressing out the core.

[0158] 5. Core ejection by pressing: By simultaneously pressing the elastic pressing blocks 91 on the outer wall of the three inner rod bodies, the inclined surface of the guide step drives the inner elastic pressing blocks 91 to move; indirectly causing the outer rod 2 to move, thereby causing the control rod 1-0 to move to the upper end of the lower guide platform 6-02, thus realizing the core ejection by pressing.

[0159] 6. Rotation and core ejection: By rotating the front rod 1a, the guide arc 92 presses the guide block 93 away from the return spring 4, and the core rod 1b moves upward relative to the outer rod 2, thereby indirectly controlling the control rod 1-0 to move to the upper end of the lower guide table 6-02, thus realizing the rotation and core ejection.

[0160] The external force refers to the force of the pen hitting an external object, the force of an external object hitting the pen, or the force generated by human interference with the pen.

[0161] The pen has at least two of the following retraction methods: 1. Lifting and retracting the core: By keeping the outer rod 2 stationary, lift the front rod 1a and the core rod 1b upwards, causing the control rod 1-0 to move upwards. Guided by the upper guide plate 6-01, the control rod 1-0 passes the limit piece 5-0 and reaches the core retracting area on the left side of the core retracting control channel 62. After releasing, the core retracting state is achieved under the action of the return spring 4.

[0162] 2. Shaking and retracting the core: Shaking the pen causes the counterweight 821 and / or impact component 833 to be affected by gravity, thereby causing the trigger main control 8 to shift. This directly or indirectly causes the limit component 5-0 to move up or down, allowing the head of the control lever 1-0 to move down beyond the limits of the limit component 5-0 and the lower guide platform 6-02, and retracting the core under the elastic force of the reset spring 4.

[0163] 3. Tapping to retract the core: Tapping the pen against an external object or vice versa will cause the counterweight 821 and / or the impact component 833 to be affected by the impact force, thereby causing the trigger main control 8 to shift. This will directly or indirectly cause the limit component 5-0 to move up or down, allowing the head of the control lever 1-0 to move down beyond the limits of the limit component 5-0 and the lower guide platform 6-02, and retract the core under the elastic force of the reset spring 4.

[0164] 4. Triggering the retraction: When the pen's counterweight 821 touches another object or another object touches the counterweight 821, this process will cause the counterweight 821 to shift, thereby causing the trigger main control 8 to shift, directly or indirectly causing the limit piece 5-0 to move up or down, so that the head of the control lever 1-0 can move down beyond the limit piece 5-0 and the lower guide platform 6-02, and the retraction is achieved under the elastic force of the reset spring 4.

[0165] 5. Vibration core retraction: The pen is dropped freely from a certain distance. This process causes the counterweight 821 and / or impact component 833 to be affected by gravity, thereby causing the trigger main control 8 to shift. This directly or indirectly causes the limit component 5-0 to move up or down, allowing the head of the control lever 1-0 to move down beyond the limits of the limit component 5-0 and the lower guide platform 6-02, and the core is retracted under the elastic force of the reset spring 4.

[0166] 6. Manual core retraction: By touching the counterweight 821, the trigger main control 8 is displaced, which directly or indirectly causes the limiter 5-0 to move up or down, so that the head of the control rod 1-0 can move down beyond the limiter 5-0 and the lower guide table 6-02, and the core is retracted under the elastic force of the reset spring 4.

[0167] 7. Pressing to retract the core: By keeping the outer rod 2 stationary, the top rod 1c is directly or indirectly controlled to move downward, causing the pressing part 6 to move downward. The upper guide plate 6-01 guides the control rod 1-0 to pass the limit piece 5-0 and reach the core retraction area on the left side of the core retraction control channel 62. After releasing the hand, the core retraction state is achieved under the action of the return spring 4.

[0168] 8. Inverted core retraction: When the pen is inverted, the gravity component 81 moves away from the pen core 3 in the impact track Q, causing the impact trigger control 5 to move upward, which causes the limit component 5-0 to move upward, so that the head of the control rod 1-0 can move downward over the limit component 5-0 and the lower guide table 6-02, and the core is retracted under the elastic force of the reset spring 4.
