Mechanical pen and operating method thereof

Abstract

The present invention relates to a pen, and in particular to a mechanical pen and an operating method thereof. The positional relationship of a tool body is determined by the displacement of an adjusting member arranged in an outer rod, and the tool body has two position states of core collection and core extraction. The adjusting member realizes the relative stability of the two position states through a positioning member or a positioning groove, a reset member and a control member on the outer rod; the reset member is transmitted through the tool body to continuously provide a continuous force to the adjusting member, so that the state of the displacement member on the adjusting member when it is located at the core collection position is relatively stable; when the displacement member moves to the core extraction position in the positioning groove, the displacement member is restricted through the control member so that the core extraction position state is relatively stable.

Description

Technical Field

[0001] The present invention relates to a pen, and in particular to a mechanical pen and an operating method thereof. Background Art

[0002] Nowadays, with the rapid development of the times, trigger-retracting pens have begun to emerge on the market. However, the structure of some trigger pens is more complicated, or they only have the function of triggering the retraction, and they cannot achieve both the lifting and triggering retraction methods at the same time, such as: CN202011512192.6 A 360-degree trigger structure and a pen using the structure; this technology realizes the 360-degree trigger retraction function of the pen, achieving an excellent function that is close to automatic retraction. This retraction method has excellent effect, and can better reflect the rapid changes of the new era and the huge upgrade of the pen's operating methods, which greatly improves people's operating experience of the pen and realizes better intelligence with mechanical technology; however, the joint bearing used in this scheme, although the joint bearing is the most stable and common structure for 360-degree rotating mechanisms in today's society, but this mature technology is too costly and difficult to produce for the 360-degree trigger retraction of the pen.

[0003] Although the core collection methods described in the reference document can achieve multiple core collection methods, this pioneering structural design, although the effect is very good, the actual triggering force required to trigger the core collection is relatively large, and it is impossible to achieve true micro-trigger core collection while ensuring stability during use.

[0004] Then it is produced in a way that is more conducive to production; and it has both the pulling and triggering core-collecting methods, and it also needs a high fault tolerance rate and a relatively stable product structure, which is convenient for promotion and mass production while being practical and providing a better experience; this requires in-depth research and development of the product, in-depth thinking, so as to cleverly solve this problem, through artificial structural design, reuse all reusable structures and channels as much as possible, and solve this problem through some clever designs.

[0005] Then the coordination and utilization rate of the structure need to be very good, and the reusable parts need to be upgraded to achieve better results. This is simple to say, but it actually requires a lot of effort to overcome the technical difficulties and limitations of thinking; it also requires the spirit of craftsmanship of continuous improvement to make a new and huge breakthrough on the premise that the existing structure is already very perfect, and realize the functions of lifting and core collection at the same time. Summary of the invention

[0006] The purpose of the invention is to solve the problems that the triggering sensitivity and stability of the existing pen triggering technology are poor, it is difficult to achieve both sensitivity and stability, the quality requirements are too high, it is difficult to achieve a high yield rate during mass production, it is impossible to have both triggering and pulling the core to retract, and the structure is complex. A mechanical pen and its operation method are provided.

[0007] In order to achieve the above-mentioned object of the invention, the present invention adopts the following technical solutions:

[0008] A mechanical pen and an operating method thereof, wherein an adjusting member disposed in an outer rod moves on a positioning groove, thereby determining the positional relationship of a tool body; the positioning groove is provided with two positional stops, namely, a core-exiting position and a core-retracting position, and the tool body has two positional states, namely, a core-retracting position and a core-exiting position, according to the position where the displacement member stops; the adjusting member realizes the relative stability of the two positional states through the positioning member or the positioning groove, the reset member and the control member on the outer rod; the reset member is transmitted through the tool body to continuously provide a continuous force to the adjusting member, so that the state of the displacement member on the adjusting member when located at the core-retracting position and the core-exiting position is relatively stable; when the displacement member moves to the core-exiting position in the positioning groove, the displacement member is restricted by the control member so that the core-exiting position state is relatively stable;

[0009] By controlling the movement of the position adjusting member, the displacement member is allowed to pass over or bypass the restriction of the control member by switching the long wall, or by moving the control member, the restriction of the control member on the displacement member is released and the displacement member returns to the core collection position, thereby achieving core collection;

[0010] By controlling the movement of the positioning member, the displacement member is moved from the core receiving position to the core output position, thereby realizing the core output.

[0011] The core-out state switches to the core-recovery state; there are fourteen methods to achieve:

[0012] 1. Mobile control core collection: The movement of the control component is affected by external force, so that the displacement component is free from the restriction of the control component. Then the displacement component will be affected by the reset component and move, thereby realizing core collection;

[0013] 2. Triggering core collection scheme 1: Through the transmission of the trigger component, the control component moves, so that the displacement component is free from the restriction of the control component, and the displacement component is affected by the reset component to move, thereby realizing core collection;

[0014] 3. Lifting and core collection scheme 1: External force controls the adjustment member to move upward, and through the switching long wall and reset member on the positioning groove, the displacement member bypasses the restriction of the limit boss and returns to the core collection position;

[0015] Fourth, the second solution of lifting and collecting the core: the external force controls the adjustment part to move upward, and the long wall is switched to reach the space above the limit boss. The external force is released through the fall-back auxiliary slope and the reset part on the control rod, so that the displacement part passes the limit of the control part and returns to the core collecting position;

[0016] 5. Pressing and core collection scheme 1: The external force controls the adjustment member to move downward, and the displacement member bypasses the limitation of the limit boss through the switching long wall on the positioning groove, and then returns to the core collection position through the reset member;

[0017] 6. Pressing and core collection scheme 2: The external force controls the adjustment part to move downward, and the long wall is switched to reach the bottom of the limit boss. The external force is released through the fall-back auxiliary slope and the reset part on the control rod, so that the displacement part passes the limit of the control part and returns to the core collection position;

[0018] 7. Pressing rod core collection scheme 1: External force squeezes one end of the pressing rod that contacts the displacement member, so that the pressing rod squeezes the displacement member out of the core-out card platform; when the displacement member is out of the core-out card platform, it is affected by the reset member and moves down to the core collection position;

[0019] 8. Press rod core collection scheme 2: External force lifts one end of the press rod away from the displacement member, so that the other end of the press rod is affected by linkage to squeeze the displacement member out of the core card platform; when the displacement member is out of the core card platform, it is affected by the reset member and moves down to the core collection position;

[0020] IX. Triggering core collection scheme 2: By triggering the transmission of the component, the control component moves, so that the displacement component is freed from the restriction of the core output card platform, and the displacement component is affected by the reset component to move, thereby realizing core collection;

[0021] 10. Lifting and core collection scheme 3: External force controls the upward movement of the adjustment member, and by not using the switching slope, the displacement member is deformed backward. When the deformation reaches a certain degree, the external force is released. Under the influence of the reset member, the displacement member will pass through the core card table, but will not cooperate with the core card table, but will directly fall into the core collection position;

[0022] 11. Reverse push core collection scheme: keep the outer rod stationary, and use external force to pull the adjustment member downward or upward. By reverse pushing the auxiliary slope, the displacement member is freed from the restriction of the core output clamping table or the core output boss, and thus returns to the core collection position;

[0023] 12. Pressing and core collecting scheme three: Pressing the trigger ring by external force makes the trigger ring squeeze the trigger cover or the trigger member, thereby making the trigger cover or the trigger member squeeze the control member, and the control member makes the displacement member move inward, thereby the displacement member and the core output card table are disengaged, and the displacement member is returned to the core collecting position through the reset member.

[0024] 13. Side-push core collection scheme 1: The side-push part is controlled to move downward by external force, and the displacement member will continue to move downward, and then pass through the core collection auxiliary wall on the positioning groove, so that the displacement member bypasses the restriction of the limit boss and returns to the core collection position through the reset member;

[0025] 14. Side-push core collection scheme 2: External force controls the side-push part to move downward, and it reaches the bottom of the limit boss through the core collection auxiliary wall. Release the external force through the return auxiliary slope and the reset part on the control rod, so that the displacement part passes the limit of the control part and returns to the core collection position.

[0026] The above-mentioned lifting core collection scheme 3, one of the two rod pressing core collection schemes, reverse push core collection scheme, pressing core collection scheme 3 and trigger core collection scheme 2 can coexist;

[0027] The above-mentioned lifting and core collecting scheme 1, lifting and core collecting scheme 2, moving control core collecting, reverse thrust core collecting scheme and trigger core collecting scheme 1 can coexist;

[0028] The above-mentioned pressing core collection scheme 1, pressing core collection scheme 2, moving control core collection, reverse push core collection scheme and trigger core collection scheme 1 can coexist.

[0029] The above-mentioned side-pushing core collection scheme 1, mobile control core collection scheme and trigger core collection scheme 1 can coexist.

[0030] Or the side-push core collection scheme 2, the mobile control core collection scheme and the trigger core collection scheme 1 can coexist.

[0031] The core receiving state is switched to the core output state by at least the following fourteen methods:

[0032] 1. Core-pulling scheme 1: The external force controls the positioning member to move upward, and through the switching long wall on the positioning groove, it moves to between the core-pulling boss and the control member and stops at the core-pulling position;

[0033] 2. Core-pulling scheme 2: Keep the outer rod stationary, and use external force to control the positioning member to move upward. When the displacement member passes through the core-pulling boss, it passes through the core-pulling auxiliary slope and the deformation and bending capacity of the displacement member, and crosses the core-pulling boss to reach the core-pulling position;

[0034] 3. Core-pulling scheme 3: External force controls the upward movement of the positioning member. When the displacement member moves from the core receiving position, it is affected by the core-outlet guide wall and enters the core-outlet channel. Then, it reaches the top of the core-outlet position by switching the long wall. At this time, when the external force is released, the displacement member will fall back to the core-outlet position.

[0035] 4. Pressing core-out scheme 1: The external force controls the positioning member to move downward, and through the switching long wall on the positioning groove, it moves to between the core-out boss and the control member and stops at the core-out position;

[0036] 5. Pressing the core out scheme 2: Keep the outer rod stationary, and use external force to control the positioning member to move downward. When the displacement member passes through the core out boss, it passes through the core out auxiliary slope and the deformation and bending capacity of the displacement member, and crosses the core out boss to reach the core out position;

[0037] 6. Pressing core-out scheme 3: External force controls the downward movement of the adjustment member. When the displacement member moves from the core receiving position, it is affected by the core-out guide wall and enters the core-out channel. Then, it reaches the top of the core-out position by switching the long wall. At this time, release the external force and the displacement member will fall back to the core-out position.

[0038] 7. Core pulling scheme 4: External force controls the adjustment member to move upward, and the displacement member moves directly from the core receiving position to the core output card table, and forms a card engagement with the core output card table, and the core output is completed;

[0039] 8. Core pulling scheme 5: External force controls the upward movement of the positioning member, and the displacement member moves upward from the core receiving position, reaches the core output card table through the extended switching slope and / or the blocking entry slope, and forms a card engagement with the core output card table, and the core output is completed.

[0040] IX. Side core ejection scheme 1: External force controls the side pusher to move downward, and through the switching long wall on the positioning groove, it moves to between the core ejection boss and the control member and stops at the core ejection position;

[0041] 10. Side core ejection scheme 2: External force controls the side pusher to move downward, and when the displacement member passes through the core ejection boss, it passes through the core ejection auxiliary slope and / or the deformation bending capacity of the displacement member, and crosses the core ejection boss to reach the core ejection position;

[0042] 11. Side core ejection scheme 3: External force controls the side pusher to move downward. When the displacement member moves from the core receiving position, it is affected by the core exiting guide wall and enters the core exiting channel. Then, it reaches the top of the core exiting position by switching the long wall. At this time, when the external force is released, the displacement member will fall back to the core exiting position.

[0043] 12. Side-pressing core-out scheme 1: When the side-pressing piece is controlled by external force to move backward, the positioning piece will move downward with the displacement piece, and thus move between the core-out boss and the control piece through the switching long wall on the positioning groove, and stop at the core-out position;

[0044] 13. Side-pressing core-out scheme 2: When the side-pressing member is controlled by external force to move backward, the positioning member will move downward with the displacement member, so that when the displacement member passes through the core-out boss, the core-out auxiliary slope and / or the deformation and bending capacity of the displacement member, it will pass over the core-out boss and reach the core-out position;

[0045] 14. Side-press core-out scheme three: When the side-pressing piece is controlled by external force to move backward, the positioning piece will move downward with the displacement piece, so that when the displacement piece moves from the core receiving position, it will be affected by the core-out guide wall and enter the core-out channel, and then reach the bottom of the core-out position by switching the long wall. At this time, release the external force and the displacement piece will fall back to the core-out position.

[0046] Among the above fourteen core-collecting methods, the core-collecting by pulling and the core-collecting by pressing cannot exist at the same time under normal circumstances, but the core-collecting by pulling or pressing can exist on the same product at the same time as the core-collecting by moving control and triggering. Two different core-collecting by pulling schemes can exist at the same time, and two different core-collecting by pressing schemes can also exist at the same time. However, under normal circumstances, only one of the core-collecting by pulling or pressing schemes needs to be adopted.

[0047] Among the above fourteen core-out methods, core-pulling and core-pressing cannot exist at the same time under normal circumstances, but core-pulling scheme 1 or core-pulling scheme 3 can exist at the same time with core-pulling scheme 2, and core-pressing scheme 1 or core-pressing scheme 3 can exist at the same time with core-pressing scheme 2. However, under normal circumstances, only one of the six core-out schemes can be selected.

[0048] The above-mentioned lifting and core collecting method can be realized in at least two ways. One is that after the control member and the auxiliary slope on the positioning groove are moved into place, the external force disappears. At this time, the displacement member will fall under the influence of the reset member and return to the core collecting position. The second way is that after the auxiliary slope on the positioning groove is moved into place, the external force disappears. At this time, the displacement member will fall under the influence of the reset member, and then pass through the auxiliary slope on the control member to cross the control member and return to the core collecting position. The positions of the auxiliary slopes of method one and method two are different, and the interference structures between the positioning member and the displacement member of method one and method two are also different, depending on the actual operating scenario. Method one is mainly used when the positioning groove is located on the positioning member or the positioning groove is located inside the outer rod, and method two is mainly used when the positioning groove is located on the outer rod.

[0049] The above-mentioned mobile control core collection and lifting core collection can be realized at the same time; the above-mentioned mobile control core collection method can be upgraded to trigger core collection by adding a trigger component. The trigger core collection is when the trigger component receives a 360-degree external force and transmits it to the control part, causing the control part to undergo corresponding displacement, thereby realizing the trigger core collection.

[0050] When the trigger core collection method is adopted, the trigger core collection and the lifting core collection can be realized at the same time.

[0051] The above-mentioned pulling out of the core, when the adjusting member is in the upper half of the outer rod as a whole, when the core is controlled by the adjusting member above the top of the outer rod, it becomes pressing the core, and the original pulling and core collection is also changed to pressing the core collection. The operation method is changed to: keep the outer rod stationary, control the adjusting member to move downward by external force, and realize pressing the core out or pressing the core collection.

[0052] When the core is pressed out or pressed in, the adjusting member is further provided with a pressing member, and the adjusting member can be better controlled by the pressing member;

[0053] When the pressing core-out and pressing core-collecting methods are adopted, the above-mentioned mobile control core-collecting also becomes another form of pressing down core-collecting. However, the trigger stroke of this pressing down core-collecting is much lower than the original pressing core-collecting. Therefore, the pressing down core-collecting is much more sensitive than the pressing core-collecting. By upgrading the trigger component, the pressing down core-collecting can also be upgraded to the trigger core-collecting.

[0054] When the pressing core is used, the pressing core and the pressing core can be realized at the same time; when the pressing core is upgraded to the trigger core, the pressing core and the trigger core can be realized at the same time.

[0055] The above simultaneous realization means that one product has these two different operating modes at the same time, thus bringing a more comprehensive and high-quality experience.

[0056] The core receiving state is switched to the core discharging state by pulling out the core: the outer rod is kept stationary, and the positioning member is controlled by external force to move the displacement member upward, thereby re-entering the restriction of the control member and the positioning groove.

[0057] A mechanical pen and an operating method thereof, comprising an outer rod, a reset member, a tool body and an adjustment module; the adjustment module comprises a control member, an adjustment member and a positioning member;

[0058] The positioning member is installed in the outer rod, and a positioning groove is provided on the positioning member;

[0059] The control member is provided with a control rod; the tail of the tool body and the tail of the positioning member are in conflict with each other;

[0060] The adjusting member is provided with a displacement member, and the displacement member is movable in the positioning groove;

[0061] The positioning groove is provided with a core receiving switching wall, a switching long wall and a core output boss; the core output boss is provided with a core output sliding wall;

[0062] The bottom of the core-collecting switching wall is the core-collecting position. At this time, the tool body remains completely hidden inside the adjusting member, which is the core-collecting state.

[0063] When the displacement member is located at the core-out sliding wall, it will be affected by the core-out sliding wall and the reset member and will move in the inclined direction of the core-out sliding wall. Before it completely leaves the core-out sliding wall, it will be limited by the control rod. Finally, the displacement member will stay on the core-out sliding wall. At this time, the position where the displacement member stays is the core-out position. At this time, it is in the core-out state.

[0064] The control rod realizes the extended core collection method of pulling and collecting the core by the following two schemes:

[0065] 1. A limiting boss is provided on the control rod, and the limiting boss replaces the control rod to limit the displacement member; when the core is collected, the displacement member moves upward, and the displacement member is freed from the limitation of the limiting boss by switching the long wall and the reset member, so as to return to the core collection position;

[0066] Second, the control rod is provided with a fall-back auxiliary slope. When collecting the core, the displacement member moves upward, leaves the space above the core-out boss by switching the long wall, and then jumps over the limit of the control rod through the reset member and the fall-back auxiliary slope.

[0067] A mechanical pen and an operating method thereof, comprising an outer rod, a reset member, a tool body and an adjustment module; the adjustment module comprises a control member and an adjustment member;

[0068] The outer rod is provided with a positioning groove and a positioning portion; the adjusting member is provided with a displacement member, and the displacement member is movable in the positioning groove;

[0069] The control member is provided with a control rod; a conflict is generated between the tail of the tool body and the positioning part;

[0070] The positioning groove is provided with a core receiving switching wall, a switching long wall and a core output boss; the core output boss is provided with a core output sliding wall;

[0071] The bottom of the core-collecting switching wall is the core-collecting position. At this time, the tool body remains completely hidden inside the adjusting member, which is the core-collecting state.

[0072] When the displacement member is located at the core-out sliding wall, it will be affected by the core-out sliding wall and the reset member and will move in the inclined direction of the core-out sliding wall. Before it completely leaves the core-out sliding wall, it will be limited by the control rod. Finally, the displacement member will stay on the core-out sliding wall. At this time, the position where the displacement member stays is the core-out position. At this time, it is in the core-out state.

[0073] The control rod realizes the extended core collection method of pulling and collecting the core by the following two schemes:

[0074] 1. A limiting boss is provided on the control rod, and the limiting boss replaces the control rod to limit the displacement member; when the core is collected, the displacement member moves upward, and the displacement member is freed from the limitation of the limiting boss by switching the long wall and the reset member, so as to return to the core collection position;

[0075] Second, the control rod is provided with a fall-back auxiliary slope. When collecting the core, the displacement member moves upward, leaves the space above the core-out boss by switching the long wall, and then jumps over the limit of the control rod through the reset member and the fall-back auxiliary slope.

[0076] A mechanical pen and an operating method thereof, comprising an outer rod, a reset member, a tool body and an adjustment module; the adjustment module comprises a control member and an adjustment member;

[0077] The control member is provided with a control rod;

[0078] The outer rod is provided with a positioning groove; the adjusting member is also provided with an adjusting conflicting portion; a conflict is generated between the tail of the tool body and the adjusting conflicting portion;

[0079] The adjusting member is provided with a displacement member, and the displacement member is movable in the positioning groove;

[0080] An auxiliary reset member is provided between the control member and the adjustment member;

[0081] The positioning groove is provided with a core receiving switching wall, a switching long wall and a core output boss; the core output boss is provided with a core output sliding wall;

[0082] The bottom of the core-collecting switching wall is the core-collecting position. At this time, the tool body remains completely hidden inside the adjusting member, which is the core-collecting state.

[0083] When the displacement member is located at the core-out sliding wall, it will be affected by the core-out sliding wall and the reset member and will move in the inclined direction of the core-out sliding wall. Before it completely leaves the core-out sliding wall, it will be limited by the control rod. Finally, the displacement member will stay on the core-out sliding wall. At this time, the position where the displacement member stays is the core-out position. At this time, it is in the core-out state.

[0084] The control rod realizes the extended core collection method of pulling and collecting the core by the following two schemes:

[0085] 1. A limiting boss is provided on the control rod, and the limiting boss replaces the control rod to limit the displacement member; when the core is collected, the displacement member moves upward, and the displacement member is freed from the limitation of the limiting boss by switching the long wall and the reset member, so as to return to the core collection position;

[0086] Second, the control rod is provided with a fall-back auxiliary slope. When collecting the core, the displacement member moves upward, leaves the space above the core-out boss by switching the long wall, and then jumps over the limit of the control rod through the reset member and the fall-back auxiliary slope.

[0087] As a preferred embodiment of the present invention: when the first lifting and core collecting scheme is adopted, a control switching wall is also provided on the control member; a core collecting channel is also provided between the limiting boss and the switching long wall and / or a core collecting channel is also provided between the limiting boss and the control switching wall.

[0088] As a preferred embodiment of the present invention: when the second lifting and core collecting scheme is adopted, a core collecting channel is further provided between the control member and the switching long wall.

[0089] 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-collecting limiting wall;

[0090] When the positioning groove is arranged on the positioning member, the positioning groove is also provided with a core-collecting limiting wall or the inner wall of the outer rod has the same function as the core-collecting limiting wall and plays a limiting role.

[0091] As a preferred embodiment of the present invention: a control rod is provided on the control member; the displacement member realizes core collection through the following five schemes:

[0092] 1. Core collection scheme 1: The control rod is provided with a limit boss; the limit boss replaces the control rod to limit the displacement member; when the core is collected, the displacement member moves up or down, and the displacement member bypasses the limit of the limit boss by switching the long wall, so as to return to the core collection position;

[0093] 2. Core collection scheme 2: The control rod is provided with a limit boss; the limit boss replaces the control rod to limit the displacement member; the limit boss is provided with a fall-back auxiliary slope; the displacement member moves up or down, reaches the upper or lower part of the limit boss by switching the long wall, and then passes through the limit of the limit boss through the fall-back auxiliary slope, so as to return to the core collection position;

[0094] 3. Core collection scheme three: The control rod is also provided with a limit boss and a control return slope; the limit boss replaces the control rod to limit the displacement member; after the control rod moves downward, the displacement member is affected by the force of the reset member and moves upward, and the control return slope is used to assist the displacement member to return to the core collection position.

[0095] 4. Mobile control core collection: The control member is forced to move by external force, so that the displacement member is free from the restriction of the control member. Then the displacement member will be affected by the reset member to move downward or upward, thereby realizing core collection;

[0096] 5. Reverse push and core collection: The displacement member and / or the core-exiting boss are also provided with a reverse push auxiliary slope; the outer rod is kept stationary, and the external force pulls the adjustment member downward, and the displacement member is freed from the restriction of the core-exiting boss through the reverse push auxiliary slope, so as to return to the core collection position. The reverse push auxiliary slope has a slope between 1 and 40 degrees, and the reverse push auxiliary slope requires the displacement member itself to have the ability to deform forward and backward.

[0097] The above five schemes can be separated into two opposite schemes according to different operation directions;

[0098] The above-mentioned schemes 1, 2, 4 and 5 can exist simultaneously, separately or in any combination;

[0099] The above-mentioned schemes 3, 4 and 5 can exist simultaneously, separately or in any combination;

[0100] The reverse thrust auxiliary slope is also used as an important parameter for assisting in adjusting the actual contact engagement force and friction between the core output card platform and the displacement member in the second trigger core collection scheme; because the second trigger core collection scheme has a very important correlation with factors such as the friction force, engagement force, deformation force of the displacement member, elastic force of the reset member and / or auxiliary reset member, and the friction force between the core output card platform and the displacement member is mainly limited by the material, surface smoothness and specific slope of the reverse thrust auxiliary slope; therefore, the reverse thrust auxiliary slope should be set appropriately according to the actual conditions such as the elastic force of the reset member and / or auxiliary reset member, the deformation force of the displacement member, the material and surface smoothness of the core output card platform and the displacement member, so that the matching force between the core output card platform and the displacement member is greater than the elastic force of the reset member, and can be kept as small as possible under normal use. In this way, it is easier to trigger the core collection scheme two!

[0101] The reverse push auxiliary slope is not very useful for the trigger core collection scheme one. After adding it, an additional reverse push core collection method can be realized. However, for stability considerations, it is better not to add it. The original pulling core collection and trigger core collection or pressing core collection and trigger core collection can fully meet the use requirements. Therefore, stability is still the most important thing.

[0102] As a preferred embodiment of the present invention, a trigger assembly is further provided on the outer rod, and the movement of the control member is affected by the trigger assembly, thereby changing the trigger form, trigger direction, trigger force and trigger range of the control member.

[0103] As a preferred embodiment of the present invention, the trigger component can be implemented in at least the following three ways:

[0104] 1.

[0120] As a preferred embodiment of the present invention, the solution for the displacement member to move from the core receiving position to the core exiting position in the positioning groove may adopt at least the following three solutions:

[0121] 1. The core-outlet boss is provided with a core-outlet auxiliary slope near the core-collecting end and / or the displacement member is provided with a core-outlet end. The displacement member itself has the ability to deform and bend forward and backward. When the displacement member passes through the core-outlet boss, it can pass through the core-outlet auxiliary slope and the deformation and bending ability of the displacement member to cross the core-outlet boss and reach the core-outlet position; 2. The core-outlet boss is also provided with a core-outlet guide wall near the core-collecting end; a core-outlet channel is also provided between the switching long wall and the core-outlet boss; when the displacement member moves up from the core-collecting end, it is affected by the core-outlet guide wall and enters the core-outlet channel, and then reaches the top of the core-outlet position through the switching long wall.

[0122] 3. The core-outlet boss is also provided with a core-outlet channel near the core-collecting position; when the displacement member moves upward from the core-collecting position, it directly enters the core-outlet channel, and then reaches the top of the core-outlet position by switching the long wall.

[0124] The above three schemes can change their set directions according to the direction of the actual operation mode. Therefore, each of the above schemes has both positive and negative changes. After extension, at least six schemes can be obtained. By adding the design of auxiliary components such as side thrusters, the possibility of the scheme can be further extended.

[0125] As a preferred embodiment of the present invention: the positioning groove is also provided with a core-out limiting wall and a core-collecting auxiliary wall; the core-out limiting wall is mainly used to limit the displacement member to prevent the displacement member from moving too far up, thereby making it impossible for the displacement member to stay at the core-out position; and the core-collecting auxiliary wall is because the length of the switching long wall becomes shorter after being blocked by the core-out limiting wall, and it is unable to continue to help the displacement member to achieve core-collecting by lifting and core-collecting. Therefore, the core-collecting auxiliary wall can replace the original function of the switching long wall and continue to help the displacement member to collect the core by pulling and core-collecting.

[0126] As a preferred embodiment of the present invention: an auxiliary resetting member is provided between the control member and the outer rod.

[0132] As a further preferred embodiment of the present invention: the control member 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. Whether to use the maximum limit for upward movement or the maximum limit for downward movement is mainly determined by whether the positioning member adopts the method of pulling out the core or pressing out the core, which can be done by limiting.

[0133] As a further preferred embodiment of the present invention: a trigger slope is added to the lower end of the trigger ring.

[0134] 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 part, which is convenient for replacing the pen core and installing it.

[0135] As a further preference of the present invention: the surface friction of the control rod and / or the trigger ring is as small as possible; the core collecting channel is provided with a channel auxiliary slope on the core outlet side, and the channel auxiliary slope can increase unnecessary interference caused by production errors and further avoid unnecessary jamming.

[0136] As a further preference of the present invention: an anti-slip boss is also provided on the positioning groove, and a fall-back channel is also provided between the limiting boss and the anti-slip boss or between the inner wall of the outer rod and the limiting boss, and the outer diameters of the fall-back channel and the core-collecting channel are both larger than the outer diameters of the displacement boss, the sliding bead and the displacement part located in the positioning groove; the function of the anti-slip boss can also be directly achieved through the inner wall of the outer rod, and it does not have to be arranged on the positioning groove.

[0137] As a further preferred embodiment of the present invention: a multi-layer height offset design is provided in the positioning groove, and the multi-layer height offset design is to design the depth of the positioning groove to be different in depth according to the moving trajectory of the displacement part, and the specific depth, and which parts are high and which parts are low, are that the core receiving part A is the highest, and then, the process from the core receiving part A to the core outlet part B decreases all the way, and then, the process from the core outlet part B to the core receiving part A from the other side is first decreased and then increased. Specifically, within a certain distance after completely leaving the core outlet part B, it still keeps decreasing, and then the process of returning to the core receiving part A gradually increases.

[0138] As a further preferred embodiment of the present invention: when a positioning member and a trigger cover are used, the trigger cover and the positioning member can be produced in an integrated manner.

[0139] As a further preferred embodiment of the present invention: the reset member and the auxiliary reset member are made of elastic material, elastic structure, repulsion force of magnetically attractable objects, springs, springs, repulsion force of magnetically attractable materials, elastic materials and / or a combination or formed separately.

[0140] As a further preferred embodiment of the present invention: the reset member and the auxiliary reset member can also replace the continuous force required in the original position from the opposite position through the tensile elastic element or the magnetic suction force.

[0141] 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 for the tool body and / or the adjusting member.

[0142] As a further preferred embodiment of the present invention: the positioning member is also provided with a control groove for accommodating the control rod to move up and down. The control rod passes through the control groove to limit the displacement convex, sliding bead, rotating member or the displacement member part located in the positioning groove from being separated from the core-out sliding wall; the control groove and the control rod are preferably extended to the same horizontal line as the core-collecting position. At this time, even if the control rod is affected by the trigger component and moves upward, when the displacement convex, rotating member, sliding bead or the displacement member located in the positioning groove releases the control rod at the moment of triggering and enters the core-collecting switching wall, there will be no displacement gap of the control rod between the control rod and the core-collecting switching wall, thereby ensuring that the entire operating system is more stable and preventing the displacement convex, rotating member, sliding bead or the 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 auxiliary slope for facilitating the sliding of the displacement member. Considering the relationship with the control groove, the displacement member may have a jamming problem. By adding the sliding auxiliary slope, the jamming caused by the fall back can be solved; the control groove can also be used as a loading slideway for the displacement convex, sliding bead or the displacement member part located in the positioning groove, which is convenient for the overall assembly.

[0143] As a further preferred embodiment of the present invention: the displacement member is also provided with a rotational interference boss for interfering with the adjusting rotating member and / or the positioning member is provided with an interference boss for interfering with the adjusting rotating member. The outer rod is provided with a built-in interference boss for interfering with the adjusting rotating member; the rotational interference boss, the interference boss and the built-in interference boss are all used to give a certain pressure to the rotating member, so that the rotating member can offset the negative interference caused by gravity; the length of the displacement part can also be lengthened so that the displacement part is interfering between the displacement part and the bottom of the positioning groove, so that the rotating member can offset the negative interference caused by gravity.

[0144] As a further preferred embodiment of the present invention: in order to facilitate the cooperation with the fall-back auxiliary slope, the core-outlet boss is provided with a corresponding fall-back small slope; the slope area of ​​the fall-back small slope is small, which will not cause the core-outlet boss to be unable to effectively cooperate with the displacement member.

[0145] As a further preferred embodiment of the present invention: in order to facilitate better cooperation with the core-out auxiliary slope, a corresponding core-out small slope is provided on the core-out boss; the slope area of ​​the core-out small slope is small and will not affect the cooperation between the displacement member and the switching long wall.

[0146] As a further preferred embodiment of the present invention: the rotating boss is offset to the side of the core collection part. When the rotating part solution is adopted, the length of the rotating part will be the problem. Due to the limitation of the internal space, the length of the rotating part cannot be too long. Therefore, it is necessary to satisfy that when the length of the rotating part is shorter, the position switching between the rotating part and the positioning groove can be normally achieved. The shorter the rotating part, the greater the rotation angle will be. As the rotation angle increases, the sliding column will easily encounter some problems in adjusting the displacement of the inner groove. This is because when the rotating part contacts the switching long wall, the angle between the two must be greater than 90 degrees, which is conducive to the rotating part passing through the switching long wall. Otherwise, it is easy to get stuck. When the rotating part contacts the core collection auxiliary wall, The angle between the two must be greater than 90 degrees to facilitate the rotating part to pass through the core-collecting auxiliary wall or the switching long wall, otherwise it will easily get stuck; when the rotating part is shorter, the increase in the rotation angle will lead to a decrease in the angle between the rotating part and the switching long wall, the angle between the rotating part and the switching long wall, and the angle between the rotating part and the core-collecting auxiliary wall. By offsetting the rotating boss as close to the core-collecting side as possible, the angle between the rotating part and the switching long wall and the angle between the rotating part and the core-collecting auxiliary wall can be increased as much as possible without adjusting other parameters, thereby increasing the fault tolerance rate and improving the overall effect and stability of the operation.

[0147] When the trigger assembly is used, the auxiliary reset member is instead arranged between the control member and the trigger cover body.

[0148] In order to adapt to tool bodies of different specifications, thereby improving the application scenarios and adaptation specifications of the tool, greatly improving the use frequency of the tool, reducing the reuse of resources, being more environmentally friendly and improving the utilization rate of the product; the structure that conflicts with the tool body is also provided with an adjustment hole, and an adjustable base is also provided in the adjustment hole, and the adjustable base and the adjustment hole are matched by threads or snaps;

[0149] The structure that is in conflict with the tool body is the part of the outer rod, the adjusting member or the positioning member that contacts the tool body;

[0150] The adjustable base changes the accommodating length of the tool body in the outer rod or the adjusting member by adjusting the positional relationship between the external adjusting tool and the adjusting hole;

[0151] The external adjustment tool is also provided with product-related scale lines or ordinary scale lines. The product-related scale lines mean that the external adjustment tool is specially made for the tool body, and the handle is provided with several commonly used specifications and lengths of the tool body. Through these scale lines of different specifications, it can be rotated to be aligned with the lower end of the outer rod or the adjustment part according to needs, and the internal length is adjusted to the internal length corresponding to the scale lines of this specification, so that consumers can directly adjust according to their needs without having to specifically remember the length parameters between different specifications.

[0152] In order to minimize the negative impact of gravity on the rotating member, a rotation stabilizing boss 45 is provided on the adjusting member 4 , and a stabilizing abutting boss 451 is further provided on the rotation stabilizing boss 45 .

[0153] In order to facilitate manufacturing, such as rapid demolding of the mold, the rotating stabilizing boss 45 can be disassembled into separate accessories and re-fixed to the adjusting member 4, the outer rod 1 or the positioning member 7 by means of installation. The installation method can be fixed by snaps, glue, magnetism, screws or third-party tools.

[0154] When the scheme of pressing the lead out and pressing the lead in is adopted, in order to prevent the lead from excessively moving backward and ensure the stability of the overall shape, the adjusting member 4 is further provided with an adjusting resistance portion 42 .

[0155] In order to improve the overall stability of the trigger core collection and ensure that the control component can be maintained in a limited state at the closest distance to the core output boss 713 in any non-triggered situation after each use, an auxiliary reset component 31 is provided between the control component 2 and the adjustment component 4.

[0156] As a further preferred embodiment of the present invention: the adjusting member is also provided with a side push portion; the outer rod is provided with a side push groove for accommodating the sliding of the side push portion; through the side push portion, the positioning member can be completely hidden in the outer rod or partially exposed, so that the core can be taken out and collected by reverse pulling at the same time, and the core can be taken out and collected by controlling the positioning member through the side push portion.

[0157] As a further preferred embodiment of the present invention: a pressing groove is also provided on the outer rod; a side pressing piece is also provided in the pressing groove, and a core-out pressing auxiliary slope used in conjunction with the side pressing piece is provided on the adjusting piece; the side pressing piece moves forward and backward relative to the pressing groove, and when the side pressing piece moves backward, it will squeeze the core-out pressing auxiliary slope, thereby causing the adjusting piece to move downward, and pressing the side pressing piece to the bottom will cause the displacement piece to move from the core receiving position to the core output position; the conversion ratio between the pressing stroke of the side pressing piece and the downward movement of the adjusting piece is affected by the slope of the core-out pressing auxiliary slope, the smaller the slope of the core-out pressing auxiliary slope, the higher the conversion ratio between the pressing stroke of the side pressing piece and the downward movement of the adjusting piece, and the side pressing piece moves a shorter distance, which can ensure that the adjusting piece moves a greater distance, thereby meeting the minimum requirement for the core-out displacement of the adjusting piece.

[0158] As a further preferred embodiment of the present invention: the side pressing piece is provided with an auxiliary insertion protrusion, and the pressing groove is also provided with an auxiliary insertion groove matched with the auxiliary insertion protrusion; when the side pressing piece is pressed to the bottom, the adjusting piece is moved down to the position, so that the core is ejected normally. At this time, because the position of the adjusting piece has reached a core ejection fixed state through the reset piece and the positioning piece, the adjusting piece will not apply a reset force to the side pressing piece at this time, and the side pressing piece will rock back and forth at this time, which will affect the core ejection state. The automatic writing process will be disturbed, causing unnecessary interference. Therefore, adding auxiliary mounting protrusions and auxiliary mounting grooves can ensure that after the side press piece is pressed to the bottom, the side press piece and the outer rod will be temporarily fixed while the positioning piece controls the core ejection. This temporary fixation is not reliable. When the automatic core retraction is triggered, the side press piece will be reset due to the influence of the reset piece on the positioning piece. The core ejection pressing auxiliary slope will prompt the side press piece to break away from the temporary fixation and reset, waiting for the next use.

[0159] When the side core is pushed out or the side core is pressed out, the tail end of the tool body does not conflict with the positioning member, but conflicts with the adjustment member, and the auxiliary reset member is also changed to be arranged between the control member and the positioning member.

[0160] The rotating part is also provided with a rotating auxiliary platform and / or a rotating installation cutout. A conflict is generated between the rotating auxiliary platform and the displacement part and / or between the rotating interference bosses. The rotating auxiliary platform can effectively help the rotating part to offset the interference of gravity. The rotating installation cutout can be used when the rotating boss is integrated between the rotating auxiliary platform and the displacement part. When the rotating part is difficult to install, the rotating part can be installed in place quickly, effectively and stably through the rotating installation cutout.

[0161] In order to ensure that the installation is simpler and more convenient, and to facilitate automation, the above-mentioned 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 cases, it is necessary to reserve a movable opening for the positioning member to move the adjusting member.

[0162] In order to ensure that the outer rod and the adjusting member are not easily separated after the assembly is completed, a positioning limit platform is further provided on the positioning member; the positioning limit platform can better resist the tool body, and at the same time, it can also form a limit with the displacement member. Before assembly, the positioning limit platform is installed into the adjusting member from the side, and after the assembly is completed, the adjusting member can only move up and down. Therefore, the positioning limit member cannot be separated from the adjusting member by moving up and down, and the positioning member will cooperate with the outer rod, which can effectively prevent the adjusting member and the outer rod from separating.

[0163] As a further preferred embodiment of the present invention: an installation buffer groove is provided in the positioning 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 with the positioning groove are made of plastic, and the positioning member needs to be installed by pushing in from bottom to top, because, considering that the displacement member 41 or other parts that replace the displacement member 41 and contact with the positioning groove are made of plastic, and this pushing in process will apply force to the adjustment member, the adjustment member will apply force to the displacement member 41 or other parts that replace the displacement member 41 and contact with the positioning groove, and the displacement member 41 will pass through the positioning groove, so that the positioning member and the outer rod or the cover body will apply force, Thus, the positioning member is stuck in the outer rod or cover body; in this case, the requirements for the displacement member 41 are relatively high. Considering the stability of long-term use, it is best not to act on the displacement member 41 with such a strong operation. Therefore, during installation, the adjustment member directly applies force to the positioning member, so that the positioning member is stuck in the outer rod or cover body. This is the best way. In this way, because it is necessary to ensure that the displacement member 41 can still move effectively in the positioning groove, the accuracy requirement is relatively high; and by adding the installation buffer groove, the requirement for this error can be improved to ensure that during installation, the adjustment member directly applies force to the positioning member, rather than the displacement member 41. This prevents the displacement member 41 from being subjected to strong impact, and improves the service life and stability of the displacement member 41.

[0164] As a further preference of the present invention: a core-collecting error groove is provided in the positioning groove; when the limiting of the core-collecting state does not need to be achieved by the restriction between the displacement member 41 or other parts that replace the displacement member 41 and contact with the positioning groove and the positioning groove, it should be avoided that when the core is collected, the displacement member or other parts that replace the displacement member 41 and contact with the positioning groove will produce unnecessary interference with the positioning groove, so as to better protect the displacement member or other parts that replace the displacement member 41 and contact with the positioning groove and the positioning groove.

[0165] As a further preference of the present invention: the rotating part and / or the rotating interference boss is also provided with a deformation groove, and the deformation groove is mainly used to help the partial structure of the original component to obtain a certain deformation ability, so as to better adapt to the engagement between the structures, and also help the rotating part or the displacement part to overcome the interference of gravity.

[0179] 2. A connector is provided on the outer rod; the trigger assembly includes a limiter, a trigger ring and a trigger cover; the limiter passes through the trigger cover and the connector to be connected to each other, and the trigger cover passes through the connector and is connected or in contact with the control member; when the trigger cover moves downward, the control member is also pressed and moved downward; the trigger ring is located between the limiter and the trigger cover; a trigger auxiliary oblique ring is provided on the lower side of the limiter, the upper side of the trigger ring, the lower side of the trigger ring and / or the upper side of the trigger cover.

[0180] As a further preferred embodiment of the present invention: the outer rod is also provided with a non-using switching slope, by not using the switching slope, the core can be pulled up and collected. When the core needs to be collected, the adjusting member is further moved upward, and by not using the switching slope, the displacement member is further deformed backward. When the deformation reaches a certain degree, the hand is released, and the elastic force of the reset member makes the speed of the displacement member falling back greater than the speed of the displacement member restoring the deformation. Then, when the displacement member passes through the core output card platform, it will not be stuck in the core output card platform again, but will fall back to the bottom, which is the limit position of the core collection.

[0181] As a further preferred embodiment of the present invention: a push rod is provided on the outer rod; a linkage channel is provided on the core output clamp table and penetrates the outer rod, and the displacement member comes into contact with the push rod through the linkage channel; the push rod is installed on the outer rod by a separate accessory or in an integral molding manner.

[0182] As a further preferred embodiment of the present invention, the push rod can be installed in a fixed manner or in a flexible manner. If the flexible manner is used, the push rod can rotate relative to the outer rod.

[0183] As a further preferred embodiment of the present invention: a pressing protrusion is provided on the pressing rod.

[0184] As a further preferred embodiment of the present invention: a displacement notch is further provided at the rear end of the displacement member.

[0185] As a further preferred embodiment of the present invention, the push rod can also be used as a pen clip, and the pen clip can be retracted.

[0186] As a further preferred embodiment of the present invention: the cover body 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 body is removed, the original outer rod structure such as the positioning part, the connecting body and the switching slope that are not used can be transferred to the cover body according to the actual application situation to facilitate installation and use.

[0187] As a further preferred embodiment of the present invention, when the displacement member is not replaced by a sliding bead, a rotating member or a third-party accessory, the displacement member is in a barbed hook shape as a whole, so as to facilitate the cooperation when the core is removed.

[0188] Compared with the prior art, the above technical solution has the following beneficial effects:

[0189] 1. Comprehensive optimization and improvement have been made to the stability of the entire pen in the ejection state, the stability of the retraction state, the stability and smoothness of switching from the ejection state to the retraction state, the stability and smoothness of switching from the retraction state to the ejection state, the integrity and stability of the appearance, the compression and optimization of the overall internal space, and the adjustment of the trigger force conversion ratio.

[0190] Second, by optimizing the structure, the effect of removing foreign objects and resetting the trigger can be achieved, the minimum force required for triggering can be reduced, the triggering effect can be greatly improved, the actual use experience can be greatly improved, and the triggering core can be better realized.

[0191] 3. Through the optimization of structural integration and removal of foreign objects and resetting, better results of reducing costs and assembly difficulty can be achieved.

[0192] Fourth, by improving the reuse rate of the structure, both the pulling and triggering core collection methods can be realized. Both core collection methods have great market value and very good user experience, and also meet the needs of different customers.

[0193] 5. It can transmit more external trigger force to better trigger the core collection.

[0194] 6. Greatly reduces the cost and assembly difficulty.

[0195] 7. The scheme of triggering the core collection of the present invention is more mature, and the actual triggering force required is several times less than that of Example 5, the triggering is more efficient, and the triggering effect is very good. This is due to the present scheme, which takes a different approach and chooses to use the core-outlet boss to bear most of the elastic force of the reset member, and uses a control member to limit the adjustment member or the displacement member from separating from the core-outlet sliding wall. At this time, the control member is equivalent to a switch, and only bears the pressure formed by the very small 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 collection position through the core-outlet sliding wall and the reset member. Moreover, this scheme does not need to consider the surface friction of the control member. Therefore, the smaller the surface friction of the control member, the smaller the surface friction of the control member, the smaller the force required for triggering, and the more sensitive the triggering.

[0196] 8. The rotating boss adopts an eccentric method to further improve the utilization rate of the internal space and ensure the stability of operation while further compressing the internal space.

[0197] 9. The use of rotating parts and rotating bosses can overcome the interference caused by gravity. Therefore, the rotation or translation problem of the displacement parts can be perfectly solved. The integrity, durability and stability of the internal structure will be greatly improved, and the smoothness and trigger sensitivity of the entire operation can also be greatly improved.

[0198] 10. The trigger ring has a trigger slope to further improve the trigger effect;

[0199] 11. If the positioning groove is placed on the positioning part, the difficulty of production and processing will be further reduced, and the difficulty of replacing parts will also be reduced. At the same time, flat positioning grooves can also be produced. With the current technology, flat surfaces are easier to produce than curved surfaces, and the accuracy and actual effect of flat surfaces will be better than those of curved surfaces, so the smoothness and stability of operation will be further improved.

[0200] 12. Strict control is exercised over every detail of the core pulling and retracting process to reduce the need for precision, thereby greatly improving the fault tolerance rate and being more conducive to production and assembly.

[0201] 13. Improve product usage and adaptation scenarios to save consumers’ money and reduce the burden on the environment.

[0202] 14. Targeted external tool design to facilitate consumers to make precise specification adjustments;

[0203] 15. Through the optimization of joint bearings, although joint bearings are mature technology and very stable, after many tests, it is found that for the 360-degree triggering of the pen, the stability of the joint bearings brings high costs to the pen and kills some possibilities;

[0204] On the contrary, the 360-degree trigger structure adopted by the present invention can achieve better technical effects due to the instability of the 360-degree trigger, which not only greatly reduces the production cost and assembly difficulty, but also has a new breakthrough in the original technical effects that can be achieved by the spherical bearing:

[0205] A semicircular trigger effect can be achieved, that is, on the basis of 360 degrees, the top oblique 360 ​​degrees and the top trigger core collection are added; this breakthrough not only brings about an extreme expansion of the trigger range, but also can achieve a better trigger effect, because the stability brought by the joint bearing will inevitably absorb the trigger force generated outside the trigger range, and this part of the trigger force cannot be transmitted; and the existence scenes of pens in real life are very changeable, so in most cases, the trigger force beyond the trigger range of the joint bearing is inevitable; and the 360-degree trigger structure adopted by the present invention; its trigger range is larger, and a semicircular trigger core collection is realized, and the trigger force of the entire semicircular range can be transmitted, so the joint bearing will consume more external trigger force, and the 360-degree trigger structure adopted by the present invention can further reduce the external trigger force consumed by the structure itself, so that when the external trigger force is inconvenient, more external trigger force can be transmitted, and the trigger core collection can be better realized;

[0206] The advantages brought by the new breakthrough include at least the following three points:

[0207] 1. A semi-circular core collection is realized, and the trigger range is greatly increased, covering 360 degrees on the side, 360 degrees on the top and 360 degrees on the top;

[0208] 2. It can transmit more external trigger force and better realize the trigger core collection;

[0209] 3. Greatly reduces the cost and assembly difficulty.

[0210] 16. The transmission method of the trigger component has been optimized, and a direct contact transmission method has been adopted. In this way, the matching points between the automatic pen clip and the pen, whether it is a hinge connection, a joint bearing, a 360-degree rotation connection or other connection methods, can be disassembled into components and hidden in the pen, and assembled in the form of assembly, which reduces the difficulty and cost of assembly, and at the same time, improves the appearance and stability of the pen.

[0211] 17. The central extrusion method is adopted to better realize the downward movement of the pressing piece; when the distance between the rotating rod and the pressing piece remains unchanged, the pressing distance of the pressing piece can be greatly expanded, which greatly improves the pressing efficiency. Fig.13 The 360° inclined downward movement adopted in the solution of switching from core output to core collection is an extrusion from the inside out. This extrusion method is more laborious, and rotates from the inside to the outside with the joint bearing as the origin. The horizontal height of the contact point between the trigger part and the internal trigger part is in a gradually rising process, and the main purpose of the inclination of the trigger part is to press the internal trigger part downward. The solution in the comparison document will have a mutual offset of the downward movement distance, resulting in a smaller final downward movement distance, so it is not efficient; and the inclined downward movement method adopts an extrusion process from the outside to the inside, which is more labor-saving, and the horizontal height of the contact point between the trigger part and the control part is gradually decreasing, so the final downward movement distance will be greater; one gains and the other loses, and the downward movement distance of this solution itself is relatively small, and the relatively increased downward movement distance appears to be quite large, making it easier to trigger the core collection.

[0212] 18. The triggering core collection scheme 1 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 this scheme takes a different approach and chooses to use the core-outlet boss to bear most of the elastic force of the reset member, and uses a control member to limit the adjustment member or the displacement member from separating from the core-outlet sliding wall. At this time, the control member is equivalent to a switch, and only bears the pressure formed by the very small 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 collection position through the core-outlet sliding wall and the reset member;

[0213] As for the triggering core collection scheme 2, the displacement part and the core output card table will be affected by the force of the reset part, which will increase the friction of the cooperation. If the friction is reduced too much by reducing the force of the reset part or making the contact surface between the displacement part and the core output card table smoother, the core output state will be unstable. Therefore, the minimum triggering force of the triggering core collection scheme 2 is limited, while the minimum triggering force of the triggering core collection scheme 1 can be very, very low. This is the reason why the triggering sensitivity of the triggering core collection scheme 2 is not as good as that of the triggering core collection scheme 1.

[0214] 19. The use of movable grooves and sliding beads can effectively solve the problem of rotation or translation of the displacement parts, and the integrity, durability and stability of the internal structure will be greatly improved, and the smoothness and trigger sensitivity of the entire operation can also be greatly improved; when sliding, it may be disturbed by gravity, but this problem can be solved by increasing the friction between parts, increasing the viscosity of the liquid, adding magnets to attract the sliding beads, using one-way limit guides to prevent the sliding beads from moving back, and / or using a multi-layer high and low offset design to prevent the sliding beads from moving back.

[0215] 20. The use of a rotating part solution can solve the rotation and translation problems of the displacement parts in the most stable way, thereby greatly improving the integrity, durability and stability of the internal structure, and greatly improving the smoothness and trigger sensitivity of the entire operation. At the same time, the anti-interference ability of the operation against gravity interference can be greatly improved, which can greatly improve the stability of the operation; by applying pressure to the rotating part and / or increasing the friction, good anti-interference ability against gravity interference can be achieved.

[0216] 21. More core ejection methods. On the basis of triggering the core collection, two new core ejection systems, side pressing and side pushing, are added to meet the needs of more users.

[0217] 22. When the side pressing and side pushing core method is adopted, the overall writing stability will be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0276] The present invention is further described below in conjunction with the accompanying drawings.

[0277] Embodiment 1:

[0278] like Figures 1 to 7 The mechanical pen and the operating method thereof shown in the figure include an outer rod 1, a reset member 3, a tool body 5 and an adjustment module. The adjustment module includes a control member 2, an adjustment member 4 and a positioning member 7.

[0279] The positioning member 7 is installed in the outer rod 1 , and a positioning groove 71 is provided on the positioning member 7 ; the control member 2 is provided with a control rod 21 .

[0280] The adjusting member 4 is provided with a displacement member 41, which is movable in the positioning groove 71. The tail of the tool body 5 is in conflict with the positioning member 7, the tool body is partially placed in the adjusting member, and the reset member is completely placed in the adjusting member.

[0281] The positioning groove 71 is provided with a core receiving switching wall 711, a switching long wall 71B and a core output boss 713. The core output boss 713 is provided with a core output sliding wall 7131.

[0282] The bottom of the core-collecting switching wall 711 is the core-collecting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-collecting state.

[0283] When the displacement member 41 is located at the core-outlet sliding wall 7131, it will be affected by the core-outlet sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-outlet sliding wall 7131. Before it completely leaves the core-outlet sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stay on the core-outlet sliding wall 7131. At this time, the position where the displacement member 41 stays is the core-outlet position B. This is the core-outlet state.

[0284] The control rod 21 realizes the extended core collection mode of lifting and collecting the core: the control rod 21 is provided with a limit boss 211 and a control switching wall 212, and the limit boss 211 replaces the control rod 21 to limit the displacement member 41. A core collection channel 214 is also provided between the limit boss 211 and the control switching wall 212. When collecting the core, the displacement member 41 moves upward, and the displacement member 41 is freed from the limit of the limit boss 211 through the core collection channel 214 and the core collection switching wall 711, so as to return to the core collection position A.

[0285] The solution for the displacement member 41 to move left or right in the positioning groove 71 is that the displacement member 41 is further provided with a rotating boss 412, and the rotating boss 412 is further provided with a rotating member 82, one end of the rotating member 82 is sleeved on the rotating boss 412, and the rotating member 82 can rotate relative to the rotating boss 412, and the other end of the rotating member 82 is provided with a displacement portion 821, and the displacement portion 821 directly contacts the positioning groove 71 instead of the displacement member 41. In addition, the displacement member 41 does not need to rotate left or right, and when it needs to move left or right, it can be rotated by the rotating member 82 relative to the rotating boss 412.

[0286] The solution for the displacement member 41 to move from the core receiving position A to the core outlet position B in the positioning groove 71 is that the core outlet boss 713 is further provided with a core outlet guide wall 7132 on the side close to the core receiving position A. A core outlet channel B2 is further provided between the switching long wall 71B and the core outlet boss 713. When the displacement member 41 moves upward from the core receiving position A, it is affected by the core outlet guide wall 7132 and enters the core outlet channel B2, and then reaches the top of the core outlet position B through the switching long wall 71B. At this time, if the external force is released, the displacement member 41 will fall back to the core outlet position B.

[0287] In order to avoid human misoperation, when the positioning groove 71 is provided with a switching long wall 71B, a core-out limiting wall 716 and a core-collecting auxiliary wall 717 may be further provided. The core-out limiting wall 716 is mainly used to limit the displacement member 41 to prevent the displacement member 41 from moving up too far, thereby making it impossible for the displacement member 41 to stay at the core-out position B. The core-collecting auxiliary wall 717 is because the switching long wall 71B is blocked by the core-out limiting wall 716, and its length becomes shorter, and it can no longer help the displacement member 41 to pull and collect the core. Therefore, the core-collecting auxiliary wall 717 can replace the original function of the switching long wall 71B and continue to help the displacement member 41 collect the core by pulling and collecting the core.

[0288] In order to trigger the core retraction, a trigger assembly 6 is also provided on the outer rod 1, which affects the movement of the control member 2 through the trigger assembly 6, thereby changing the trigger form, trigger direction, trigger force and trigger range of the control member 2. The trigger assembly 6 includes a limit member 61, a trigger ring 62 and a trigger cover 63. The limit member 61 passes through the trigger cover 63 and is connected to the control member 2, and the control member 2 moves with the limit member 61. The trigger cover 63 and the outer rod 1 are connected to each other. The trigger ring 62 is located between the limit member 61 and the trigger cover 63. A trigger auxiliary oblique ring C is provided on the lower side of the limit 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.

[0289] In order to make the trigger assembly more stable as a whole and to enable normal and stable triggering when the pen body is tilted, an auxiliary reset member 31 is provided between the control member 2 and the outer rod 1 .

[0290] In order to ensure that the trigger is easier to trigger, the outer diameter of the trigger ring 62 is larger than the outer diameter of the outer rod 1. A trigger slope 621 is added to the lower end of the trigger ring 62. The surface friction of the control rod and / or the trigger ring is as small as possible. The inclination angle of the trigger slope is determined by the set trigger inclination angle. For example, when the inclination is 10°, the trigger core can be completed. The inclination angle of the slope is more than 10°, which is convenient for improving the trigger effect.

[0291] In order to ensure that the control member can play a more stable control role, the control member 2 and the outer rod 1 can only move up and down but cannot rotate left and right, and there is a maximum limit for downward movement.

[0292] In order to improve unnecessary interference caused by production errors and further avoid unnecessary jamming, the core collecting channel 214 is provided with a channel auxiliary slope 2141 on the side B of the core outlet.

[0293] In order to ensure the stability of the fall back, an anti-slip boss 719 is further provided on the positioning groove 71 , and a fall back channel 71A is further provided between the limiting boss 211 and the anti-slip boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211 .

[0294] In order to ensure that the control rod can play a better role, the positioning member 7 is also provided with a control groove 715 for accommodating the up and down movement of the control rod 21. The control rod 21 passes through the control groove 715 to limit the displacement part 821 of the rotating member 82 from being separated from the core-out sliding wall 7131. It is better that the control groove 715 and the control rod 21 are extended to the same horizontal line as the core-collecting position A. At this time, even if the control rod 21 is affected by the trigger assembly 6 and moves upward, when the displacement part 821 releases the control rod 21 at the moment of triggering and enters the core-collecting switching wall 711, there will be no displacement gap of the control rod 21 between the control rod 21 and the core-collecting switching wall 711, thereby ensuring that the entire operating system is more stable and preventing the displacement part 821 from accidentally falling into the displacement gap of the control rod 21. The positioning groove 71 is also provided with a sliding auxiliary slope 718 for facilitating the sliding of the displacement member 41. Considering the relationship with the control groove 715, the displacement member 41 may have a jamming problem. By adding the sliding auxiliary slope 718, the jamming caused by the fall back can be solved. The control groove 715 can also be used as a slideway for the displacement portion 821 to facilitate overall assembly.

[0295] In order to enable the rotating member to offset the negative interference caused by gravity, the displacement member 41 is also provided with a rotational interference boss 413 for interfering with the adjusting rotating member 82 and / or the positioning member 7 is provided with an interference boss for interfering with the adjusting rotating member 82. The outer rod 1 is provided with a built-in interference boss for interfering with the adjusting rotating member 82. The rotational interference boss 413, the interference boss and the built-in interference boss are all used to give a certain pressure to the rotating member 82, so that the rotating member 82 offsets the negative interference caused by gravity. The length of the displacement part 821 can also be lengthened so that the displacement part 821 is between the displacement member 41 and the bottom of the positioning groove 71; the main method is to rely on the deformation ability of the displacement member 41 and / or the rotating member 82 itself, and by applying pressure to the displacement member 41 and / or the rotating member 82, the friction and pressure between the rotating member 82 and the structure in contact with the rotating member 82 are increased, so that the negative interference caused by gravity is offset.

[0296] In order to utilize the internal space more efficiently, improve the utilization rate of the space, and ensure the best stability, the above-mentioned rotating boss 412 is offset to the side A of the core receiving portion. When the rotating member 82 solution is adopted, the length problem of the rotating member 82 will be faced. Due to the limitation of the internal space, the length of the rotating member 82 cannot be too long. It is necessary to meet the requirement that when the length of the rotating member 82 is shorter, the position switching between the rotating member 82 and the positioning groove 71 can be normally achieved. The shorter the rotating member, the greater the rotation angle will be. As the rotation angle increases, the sliding column will easily encounter some problems in adjusting the displacement of the inner groove, such as jamming and stuck, because when the rotating member contacts the switching long wall, the angle between the two must be greater than 90 degrees, which is conducive to the rotating member passing through the switching long wall, otherwise it is easy to get stuck. When the rotating member contacts the core receiving auxiliary wall, the angle between the two must also be greater than 90 degrees, which is conducive to the rotating member passing through the core receiving auxiliary wall or the switching long wall, otherwise it is easy to get stuck. When the rotating part is shorter, the increase in the rotation angle will lead to a decrease in the angle between the rotating part and the switching long wall, the angle between the rotating part and the switching long wall, and the angle between the rotating part and the core-collecting auxiliary wall. Based on the situation that the inclination angles of the switching long wall, the switching long wall, the core-collecting auxiliary wall and the horizontal line remain unchanged, and by offsetting the rotating boss as close to the core-collecting side as possible, the angle between the rotating part and the switching long wall, and the angle between the rotating part and the core-collecting auxiliary wall can be increased as much as possible without adjusting other parameters, thereby increasing the fault tolerance rate and improving the overall effect and stability of the operation.

[0297] In order to further improve the fault tolerance rate: the lower end point of the control switching wall 212 is higher than the upper end point of the core collecting auxiliary wall 717, which can achieve better effect.

[0298] In order to facilitate the auxiliary reset of the card holder, a reset ring 24 is also provided on the control member 2.

[0299] In order to further improve the tolerance of the displacement member 41 falling back, a limiting falling back slope 2111 is further provided on the limiting boss 211 .

[0300] In order to ensure that the installation is simpler, more convenient and easier to automate, the above-mentioned adjusting member 4 is further provided with an active opening 43; the above-mentioned active opening 43 is further provided with a clamping extension 431, and the above-mentioned clamping extension 431 is adapted to the positioning member 7. After the above-mentioned positioning member 7 is clamped into the clamping extension 431, it can slide up and down relative to the adjusting member 4, and it is not easy to be separated from the cooperation with the adjusting member 4 even when the outer rod 1 is not installed; the above-mentioned active 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 terms of the situation described in some embodiments, the positioning member 7 needs to enter the adjusting member 4. Therefore, in certain cases, it is necessary to reserve an active opening 43 of the moving stroke of the adjusting member 4 for the positioning member 7;

[0301] In order to ensure that the outer rod and the adjusting member are not easily separated after the assembly is completed, a positioning limit platform 7B is further provided on the positioning member 7; the positioning limit platform 7B can better resist the tool body 5, and at the same time, it can also form a limit with the displacement member 41. Before assembly, the positioning limit platform 7B is installed into the adjusting member 4 from the side, and after the assembly is completed, the adjusting member 4 can only move up and down. Therefore, the positioning limit member 7B cannot be separated from the adjusting member 4 by moving up and down, and the positioning member 7 will cooperate with the outer rod, which can effectively prevent the adjusting member 4 and the outer rod 1 from separating.

[0302] In order to better fix the rotating member 82, the displacement member 41 is further provided with a rotating fastener 4121 for contacting the rotating member 82, and the rotating fastener 4121 is divided into a clamping portion 4131 and a snap-in portion 4132. The rotating fastener 4121 is snap-fitted into the side of the displacement member 41 through the snap-in portion 4132, and the displacement member 41 is also provided with a corresponding clamping slot 41Y. After the snap-in portion 4132 is snapped into the clamping slot 41Y, the clamping portion 4131 continuously applies a clamping force to the rotating member 82, so that the rotating member 82 has a certain damping effect when rotating left and right, thereby overcoming the interference of gravity.

[0303] Installation method:

[0304] 1. First, assemble the positioning part, the rotating part and the adjusting part into an adjusting assembly. One end of the rotating part is sleeved on the rotating boss of the adjusting part. Insert the positioning part into the adjusting part, and then install the displacement part at the other end into the positioning groove. At this point, the adjusting assembly is completed.

[0305] 2. Then install the adjustment component into the outer rod from top to bottom. The adjustment component cannot be moved downward excessively due to the limit between the positioning piece and the outer rod. When the positioning piece stays at the installation position, the control piece, the auxiliary reset piece and the trigger cover body are installed into the outer rod from top to bottom in sequence;

[0306] 3. Then, place the trigger ring on the trigger cover, pass the limiter through the trigger ring and the trigger cover, and assemble it with the control part; then the whole assembly is roughly completed;

[0307] 4. Finally, install the tool body, reset part, and pen changer into the adjustment part from bottom to top, and then install the pen changer and adjustment part in place.

[0308] Core removal method:

[0309] The third core-pulling scheme is adopted: external force controls the upward movement of the adjusting member 4. When the displacement member 41 moves from the core receiving position A, it is affected by the core-outlet guide wall 7132 and enters the core-outlet channel B2. Then, it reaches the top of the core-outlet position B by switching the long wall 71B. At this time, the external force is released, and the displacement member 41 will fall back to the core-outlet position B.

[0310] There are two ways to collect the core:

[0311] 1. Triggering core collection scheme 1: The product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limiter 61, and the limiter 61 will move up, thereby driving the control member 2 to move up. When the control member 2 moves up, the displacement part 821 loses the restriction of the control member 2 and slides down along the core-outlet sliding wall 7131 to the core collection position A. At this time, the tool body will be completely hidden in the pen-changing part D;

[0312] 2. Lifting and core collection scheme 1: External force controls the adjustment member 4 to move upward, and through the core collection auxiliary wall 717 on the positioning groove 71 and the control switching wall 212 on the control member 2, the displacement member 41 bypasses the restriction of the limiting boss 211 and is affected by the reset member 3 to fall back to the core collection position A.

[0313] Embodiment 2:

[0314] like Figures 8 to 13 The mechanical pen and the operating method thereof shown in the figure include an outer rod 1, a reset member 3, a tool body 5 and an adjustment module. The adjustment module includes a control member 2 and an adjustment member 4.

[0315] The control member 2 is provided with a control rod 21 ; the outer rod 1 is provided with a positioning groove 71 .

[0316] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 is movable in the positioning groove 71 .

[0317] When the pressing-pushing-out and pressing-pushing-in schemes are adopted, in order to prevent the lead from excessively moving backward and ensure the stability of the overall shape, the adjusting member 4 is further provided with an adjusting abutment portion 42. The tail of the tool body 5 is in conflict with the adjusting abutment portion 42, and the tool body 5 and the reset member are completely placed in the outer rod.

[0318] In order to improve the overall stability of the trigger core collection and ensure that the control component can be maintained in a limited state at the closest distance to the core output boss 713 in any non-triggered situation after each use, an auxiliary reset component 31 is provided between the control component 2 and the adjustment component 4.

[0319] The positioning groove 71 is provided with a core receiving switching wall 711, a switching long wall 71B and a core output boss 713. The core output boss 713 is provided with a core output sliding wall 7131.

[0320] The bottom of the core-collecting switching wall 711 is the core-collecting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-collecting state.

[0321] When the displacement member 41 is located at the core-outlet sliding wall 7131, it will be affected by the core-outlet sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-outlet sliding wall 7131. Before it completely leaves the core-outlet sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stay on the core-outlet sliding wall 7131. At this time, the position where the displacement member 41 stays is the core-outlet position B. This is the core-outlet state.

[0322] The above-mentioned control rod 21 realizes an extended core-collecting method of lifting and collecting the core: the above-mentioned control rod 21 is provided with a fall-back auxiliary slope 213. When collecting the core, the above-mentioned displacement member 41 moves up, leaves the space above the core-outlet boss 713 by switching the long wall 71B, and then jumps over the limitation of the control rod 21 through the reset member 3 and the fall-back auxiliary slope 213.

[0323] The solution for the displacement member 41 to move leftward or rightward in the positioning groove 71 is that the displacement member 41 is further provided with a displacement cam 411. The displacement cam 411 directly contacts the positioning groove 71 instead of the displacement member 41. The displacement member 41 itself has a certain left-right deformation bending ability and can bend to a certain extent, so as to meet the situation that the displacement member 41 will move leftward or rightward when moving in the positioning groove 71, under the premise that the adjustment member 4 itself does not move.

[0324] The solution for the displacement member 41 to move from the core receiving position A to the core exiting position B in the positioning groove 71 is that the core exiting boss 713 is provided with a core exiting auxiliary slope B1 near the core receiving position A end and / or the displacement member 41 is provided with a core exiting auxiliary slope B1 near the core exiting position B end. The displacement member 41 itself has the ability to deform and bend forwards and backwards. When the displacement member 41 passes through the core exiting boss 713, it can pass through the core exiting auxiliary slope B1 and the deformation and bending ability of the displacement member 41 to cross the core exiting boss 713 and reach the core exiting position B.

[0325] In order to achieve the trigger core retraction, a trigger assembly 6 is also provided on the outer rod 1, and the movement of the control member 2 is affected by the trigger assembly 6, thereby changing the trigger form, trigger direction, trigger force and trigger range of the control member 2. A connector 11 is provided on the outer rod 1. The trigger assembly 6 includes a limiter 61, a trigger ring 62 and a trigger cover 63. The limiter 61 passes through the trigger cover 63 and is connected to the connector 11, and the trigger cover 63 passes through the connector 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 limiter 61 and the trigger cover 63. A trigger auxiliary oblique ring C is provided on the lower side of the limiter 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.

[0326] In order to make the trigger assembly more stable as a whole and to enable normal and stable triggering when the pen body is tilted, an auxiliary reset member 31 is provided between the control member 2 and the outer rod 1 .

[0327] In order to ensure that the trigger is easier to trigger, the outer diameter of the trigger ring 62 is greater than the outer diameter of the outer rod 1. The smaller the surface friction of the control rod and / or the trigger ring, the better.

[0328] In order to ensure that the control member can play a more stable control role, the control member 2 and the outer rod 1 can only move up and down but cannot rotate left and right, and there is a maximum limit for upward movement.

[0329] The core-collecting state is switched to the core-exiting state: by using external force, while keeping the outer rod 1 stationary, the adjusting member 4 is moved to move the displacement member 41 from the core-collecting position A to the bottom of the core-exiting boss 713, and then the external force is released, and the displacement member 41 falls back under the influence of the reset member 3, contacts the core-exiting sliding wall 7131 and the control rod 21, and stays at the core-exiting position B.

[0330] In order to achieve better pressing, a pressing piece 43 is provided, and the pressing piece 43 cooperates with the adjusting piece.

[0331] In order to facilitate the auxiliary reset of the card holder, a reset ring 24 is also provided on the control member 2.

[0332] In order to adapt to tool bodies of different specifications, thereby improving the application scenarios and adaptation specifications of the tool, greatly improving the use frequency of the tool, reducing the reuse of resources, being more environmentally friendly and improving the utilization rate of the product; the structure that conflicts with the tool body 5 is also provided with an adjustment hole E1, and an adjustable base E is also provided in the adjustment hole E1, and the adjustable base E and the adjustment hole E1 are matched by threads or snaps; the structure that conflicts with the tool body 5 is the part of the outer rod 1, the adjustment member 4 or the positioning member 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 Change the accommodating length of the tool body 5 inside the outer rod 1 or the adjusting member 4; the above-mentioned external adjustment tool is also provided with product-related scale lines or ordinary scale lines. The above-mentioned product-related scale lines mean that the external adjustment tool is specially made for the tool body 5, and the handle is provided with scale lines of several commonly used lengths of the tool body 5. Through these scale lines of different specifications, it can be rotated to be aligned with the lower end of the outer rod 1 or the adjusting member 4 according to needs, and the internal length is adjusted to the internal length corresponding to the scale lines of this specification, which is convenient for consumers to adjust directly according to needs without having to specially remember the length parameters between different specifications.

[0333] Installation method:

[0334] 1. First, install the trigger cover, trigger ring and limiter into the outer rod from top to bottom in sequence. The limiter passes through the trigger ring, trigger cover and connector to cooperate.

[0335] 2. Install the positioning piece, auxiliary reset piece, adjustment piece, refill, reset piece and pen changing part into the outer rod from bottom to top, and match the pen changing part with the outer rod;

[0336] 3. Finally, match the pressing piece and the adjusting piece.

[0337] The core-out method adopts the second pressing core-out scheme: keep the outer rod 1 stationary, and control the positioning member 4 to move downward by external force. When the displacement member 41 passes through the core-out boss 713, it passes through the core-out auxiliary slope B1 and the deformation and bending ability of the displacement member 41, and crosses the core-out boss 713 to reach the core-out position B.

[0338] There are two ways to collect the core:

[0339] 1. Triggering core collection scheme 1: The product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and 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 downward, thereby driving the control member 2 to move downward. When the control member 2 moves downward, the displacement boss 411 loses the restriction of the control member 2 and slides down along the core-outlet sliding wall 7131 to the core collection position A. At this time, the tool body will be completely hidden in the pen-changing portion D;

[0340] 2. Press and hold core collection scheme 2: external force controls the adjustment member 4 to move downward, and reaches the bottom of the limit boss 211 by switching the long wall 71B. Release the external force through the return auxiliary slope 213 and the reset member 3 on the control rod 21, so that the displacement member 41 passes the limit of the control member 2 and returns to the core collection position A.

[0341] Embodiment 3:

[0342] like Figures 14 to 18 The mechanical pen and the operating method thereof shown in the figure include an outer rod 1, a reset member 3, a tool body 5 and an adjustment module. The adjustment module includes a control member 2 and an adjustment member 4.

[0343] The outer rod 1 is provided with a positioning groove 71 and a positioning portion 72. The adjusting member 4 is provided with a displacement member 41, and the displacement member 41 is movable in the positioning groove 71.

[0344] The control member 2 is provided with a control rod 21. The tail of the tool body 5 is in conflict with the positioning portion 72, the tool body 5 is partially placed in the adjustment member 4, and the reset member 3 is completely placed in the adjustment member 4. The positioning groove 71 is provided with a core receiving switching wall 711, a switching long wall 71B and a core output boss 713. The core output boss 713 is provided with a core output sliding wall 7131.

[0345] The bottom of the core-collecting switching wall 711 is the core-collecting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-collecting state.

[0346] When the displacement member 41 is located at the core-outlet sliding wall 7131, it will be affected by the core-outlet sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-outlet sliding wall 7131. Before it completely leaves the core-outlet sliding wall 7131, it will be limited by the control rod 21. Finally, the displacement member 41 will stay on the core-outlet sliding wall 7131. At this time, the position where the displacement member 41 stays is the core-outlet position B. This is the core-outlet state.

[0347] The above-mentioned control rod 21 realizes an extended core-collecting method of lifting and collecting the core: the above-mentioned control rod 21 is provided with a fall-back auxiliary slope 213. When collecting the core, the above-mentioned displacement member 41 moves up, leaves the space above the core-outlet boss 713 by switching the long wall 71B, and then jumps over the limitation of the control rod 21 through the reset member 3 and the fall-back auxiliary slope 213.

[0348] The solution for the displacement member 41 to move leftward or rightward in the positioning groove 71 is that the displacement member 41 is further provided with a displacement cam 411. The displacement cam 411 directly contacts the positioning groove 71 instead of the displacement member 41. The displacement member 41 itself has a certain left-right deformation bending ability and can bend to a certain extent, so as to meet the situation that the displacement member 41 will move leftward or rightward when moving in the positioning groove 71, under the premise that the adjustment member 4 itself does not move.

[0349] The solution for the displacement member 41 to move from the core receiving position A to the core exiting position B in the positioning groove 71 is that the core exiting boss 713 is provided with a core exiting auxiliary slope B1 near the core receiving position A end and / or the displacement member 41 is provided with a core exiting auxiliary slope B1 near the core exiting position B end. The displacement member 41 itself has the ability to deform and bend forwards and backwards. When the displacement member 41 passes through the core exiting boss 713, it can pass through the core exiting auxiliary slope B1 and the deformation and bending ability of the displacement member 41 to cross the core exiting boss 713 and reach the core exiting position B.

[0350] In order to trigger the core retraction, a trigger assembly 6 is also provided on the outer rod 1, which affects the movement of the control member 2 through the trigger assembly 6, thereby changing the trigger form, trigger direction, trigger force and trigger range of the control member 2. The trigger assembly 6 includes a limit member 61, a trigger ring 62 and a trigger cover 63. The limit member 61 passes through the trigger cover 63 and is connected to the control member 2, and the control member 2 moves with the limit member 61. The trigger cover 63 and the outer rod 1 are connected to each other. The trigger ring 62 is located between the limit member 61 and the trigger cover 63. A trigger auxiliary oblique ring C is provided on the lower side of the limit 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.

[0351] In order to ensure that the trigger is easier to trigger, the outer diameter of the trigger ring 62 is greater than the outer diameter of the outer rod 1. The smaller the surface friction of the control rod and / or the trigger ring, the better.

[0352] In order to ensure that the control member can play a more stable control role, the control member 2 and the outer rod 1 can only move up and down but cannot rotate left and right, and there is a maximum limit for downward movement.

[0353] The core-collecting state is switched to the core-exiting state: by means of external force, while keeping the outer rod 1 stationary, the adjusting member 4 is moved to move the displacement member 41 from the core-collecting position A to above the core-exiting boss 713, and then the external force is released, and the displacement member 41 falls back under the influence of the reset member 3, contacts the core-exiting sliding wall 7131 and the control rod 21, and stays at the core-exiting position B.

[0354] In order to better prevent the adjusting member 4 from being separated from the outer rod, the displacement boss 411 can be separated independently, and after the adjusting member is installed in the outer rod, the adjusting member 4 is installed separately; then the adjusting member 4 is not easy to be separated from the outer rod.

[0355] In order to adapt to tool bodies of different specifications, thereby improving the application scenarios and adaptation specifications of the tool, greatly improving the use frequency of the tool, reducing the reuse of resources, being more environmentally friendly and improving the utilization rate of the product; the structure that conflicts with the tool body 5 is also provided with an adjustment hole E1, and an adjustable base E is also provided in the adjustment hole E1, and the adjustable base E and the adjustment hole E1 are matched by threads or snaps; the structure that conflicts with the tool body 5 is the part of the outer rod 1, the adjustment member 4 or the positioning member 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 Change the accommodating length of the tool body 5 inside the outer rod 1 or the adjusting member 4; the above-mentioned external adjustment tool is also provided with product-related scale lines or ordinary scale lines. The above-mentioned product-related scale lines mean that the external adjustment tool is specially made for the tool body 5, and the handle is provided with scale lines of several commonly used lengths of the tool body 5. Through these scale lines of different specifications, it can be rotated to be aligned with the lower end of the outer rod 1 or the adjusting member 4 according to needs, and the internal length is adjusted to the internal length corresponding to the scale lines of this specification, which is convenient for consumers to adjust directly according to needs without having to specially remember the length parameters between different specifications.

[0356] In order to enable the adjusting member to rotate better and thus facilitate switching of the position state, a pen-changing part D is further provided under the adjusting member 4, and two magnetically attractive objects H are further provided between the adjusting member 4 and the pen-changing part D. The magnetic attraction between the two magnetically attractive objects H is utilized to enable the adjusting member 4 and the pen-changing part D to cooperate with each other, and at the same time, it can also ensure that the adjusting member 4 can rotate relative to the pen-changing part D.

[0357] Installation method:

[0358] 1. Install the control part, trigger cover, trigger ring and limiter into the outer rod from top to bottom in sequence, the trigger cover and the outer rod are matched, and the limiter passes through the trigger ring, trigger cover and control part to match;

[0359] 2. Install the adjustable base E into the outer rod through the external adjustment tool and adjust it into place according to the actual required size of the tool body;

[0360] 3. Then install the adjusting part, tool body, reset part and pen changing part into the outer rod from bottom to top, and the pen changing part and adjusting part are matched;

[0361] 4. At this time, it can be checked whether the lower displacement boss 411 is located in the positioning groove 71. If not, adjust the position of the adjustment member to ensure that the displacement boss 411 is placed in the positioning groove 71.

[0362] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the entire pen should be erected before the core is ejected, which can ensure the success rate of core ejection. Of course, an auxiliary reset component can also be directly added between the control component and the trigger cover to improve the operating experience.

[0363] Core-out method: adopt the second core-out scheme: keep the outer rod 1 stationary, and use external force to control the positioning member 4 to move upward. When the displacement member 41 passes through the core-out boss 713, it passes through the core-out auxiliary slope B1 and the deformation and bending ability of the displacement member 41, and crosses the core-out boss 713 to reach the core-out position B;

[0364] There are two ways to collect the core:

[0365] 1. Triggering core collection scheme 1: The product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limiter 61, and the limiter 61 will move up, thereby driving the control member 2 to move up. When the control member 2 moves up, the displacement boss 411 loses the restriction of the control member 2 and slides down along the core-outlet sliding wall 7131 to the core collection position A. At this time, the tool body will be completely hidden in the pen-changing part D;

[0366] 2. Lifting and core collection scheme 2: External force controls the adjustment member 4 to move upward, and reaches the space above the limiting boss 211 by switching the long wall 71B. Release the external force through the return auxiliary slope 213 and the reset member 3 on the control rod 21, so that the displacement member 41 passes the limit of the control member 2 and returns to the core collection position A.

[0367] Embodiment 4:

[0368] like Figures 19 to 23A mechanical pen and an operating method thereof are shown, wherein the positional relationship of the tool body is determined by the displacement of an adjusting member disposed in an outer rod, and the tool body has two position states of core collection and core extraction. The adjusting member realizes the relative stability of the two position states through a positioning member or a positioning groove, a reset member and a control member on the outer rod; the reset member is transmitted through the tool body to continuously provide a continuous force to the adjusting member, so that the state of the displacement member on the adjusting member when it is located at the core collection position is relatively stable; when the displacement member moves from the positioning groove to the core extraction position, the displacement member is restricted through the control member so that the core extraction position state is relatively stable;

[0369] The above core-out state switches to the core-recovery state; there are three ways to achieve this:

[0370] 1. Mobile control core collection: through external force to affect the upward or downward movement of the control member, so that the displacement member is free from the restriction of the control member, the displacement member will be affected by the reset member to move downward, thereby achieving core collection;

[0371] 2. Lift and retract the core: Keep the outer rod stationary, and use external force to control the adjustment part to move upward. Through the switching long wall on the positioning groove, the control switching wall on the control part and the reset part, the displacement part bypasses the restriction of the control part and returns to the core retracting position;

[0372] 3. Lifting and core collection plan 2: Keep the outer rod stationary, and use external force to control the adjustment part to move up. Through the switching long wall and reset part on the positioning groove, the displacement part passes the limit of the control part and returns to the core collection position.

[0373] The solution for the displacement member 41 to move left or right in the positioning groove 71 is that the displacement member 41 is further provided with a rotating boss 412, and the rotating boss 412 is further provided with a rotating member 82, one end of the rotating member 82 is sleeved on the rotating boss 412, and the rotating member 82 can rotate relative to the rotating boss 412, and the other end of the rotating member 82 is provided with a displacement portion 821, and the displacement portion 821 directly contacts the positioning groove 71 instead of the displacement member 41. In addition, the displacement member 41 does not need to rotate left or right, and when it needs to move left or right, it can be rotated by the rotating member 82 relative to the rotating boss 412.

[0374] The solution for the displacement member 41 to move from the core receiving position A to the core outlet position B in the positioning groove 71 is that the core outlet boss 713 is further provided with a core outlet guide wall 7132 on the side close to the core receiving position A. A core outlet channel B2 is further provided between the switching long wall 71B and the core outlet boss 713. When the displacement member 41 moves upward from the core receiving position A, it is affected by the core outlet guide wall 7132 and enters the core outlet channel B2, and then reaches the top of the core outlet position B through the switching long wall 71B. At this time, if the external force is released, the displacement member 41 will fall back to the core outlet position B.

[0375] In order to avoid human misoperation, the positioning groove 71 is also provided with a core-exit limiting wall 716 and a core-collecting auxiliary wall 717. The core-exit limiting wall 716 is mainly used to limit the displacement member 41 to prevent the displacement member 41 from moving too far upward, thereby making it impossible for the displacement member 41 to stay at the core-exit position B. The core-collecting auxiliary wall 717 is because the length of the switching long wall 71B becomes shorter after being blocked by the core-exit limiting wall 716, and it can no longer help the displacement member 41 to pull and collect the core. Therefore, the core-collecting auxiliary wall 717 can replace the original function of the switching long wall 71B and continue to help the displacement member 41 collect the core by pulling and collecting the core.

[0376] In order to ensure that the control member can play a more stable control role, the control member 2 and the outer rod 1 can only move up and down but cannot rotate left and right, and there is a maximum limit for downward movement.

[0377] In order to improve unnecessary interference caused by production errors and further avoid unnecessary jamming, the core collecting channel 214 is provided with a channel auxiliary slope 2141 on the side B of the core outlet.

[0378] In order to ensure the stability of the fall back, an anti-slip boss 719 is further provided on the positioning groove 71 , and a fall back channel 71A is further provided between the limiting boss 211 and the anti-slip boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211 .

[0379] In order to ensure that the control rod can play a better role, the positioning member 7 is also provided with a control groove 715 for accommodating the up and down movement of the control rod 21. The control rod 21 passes through the control groove 715 to limit the displacement part 821 of the rotating member 82 from being separated from the core-out sliding wall 7131. It is better that the control groove 715 and the control rod 21 are extended to the same horizontal line as the core-collecting position A. At this time, even if the control rod 21 is affected by the trigger assembly 6 and moves upward, when the displacement part 821 releases the control rod 21 at the moment of triggering and enters the core-collecting switching wall 711, there will be no displacement gap of the control rod 21 between the control rod 21 and the core-collecting switching wall 711, thereby ensuring that the entire operating system is more stable and preventing the displacement part 821 from accidentally falling into the displacement gap of the control rod 21. The positioning groove 71 is also provided with a sliding auxiliary slope 718 for facilitating the sliding of the displacement member 41. Considering the relationship with the control groove 715, the displacement member 41 may have a jamming problem. By adding the sliding auxiliary slope 718, the jamming caused by the fall back can be solved. The control groove 715 can also be used as a slideway for the displacement portion 821 to facilitate overall assembly.

[0380] In order to enable the rotating member to offset the negative interference caused by gravity, the displacement member 41 is also provided with a rotational interference boss 413 for interfering with the adjusting rotating member 82 and / or the positioning member 7 is provided with an interference boss for interfering with the adjusting rotating member 82. The outer rod 1 is provided with a built-in interference boss for interfering with the adjusting rotating member 82. The rotational interference boss 413, the interference boss and the built-in interference boss are all used to give a certain pressure to the rotating member 82, so that the rotating member 82 offsets the negative interference caused by gravity. The displacement portion 821 can also be made to contact between the displacement member 41 and the bottom of the positioning groove 71 by lengthening the length of the displacement portion 821.

[0381] In order to utilize the internal space more efficiently, improve the utilization rate of the space, and ensure the best stability, the above-mentioned rotating boss 412 is offset to the side A of the core receiving portion. When the rotating member 82 solution is adopted, the length problem of the rotating member 82 will be faced. Due to the limitation of the internal space, the length of the rotating member 82 cannot be too long. It is necessary to meet the requirement that when the length of the rotating member 82 is shorter, the position switching between the rotating member 82 and the positioning groove 71 can be normally achieved. The shorter the rotating member, the greater the rotation angle will be. As the rotation angle increases, the sliding column will easily encounter some problems in adjusting the displacement of the inner groove, such as jamming and stuck, because when the rotating member contacts the switching long wall, the angle between the two must be greater than 90 degrees, which is conducive to the rotating member passing through the switching long wall, otherwise it is easy to get stuck. When the rotating member contacts the core receiving auxiliary wall, the angle between the two must also be greater than 90 degrees, which is conducive to the rotating member passing through the core receiving auxiliary wall or the switching long wall, otherwise it is easy to get stuck. When the rotating part is shorter, the increase in the rotation angle will lead to a decrease in the angle between the rotating part and the switching long wall, the angle between the rotating part and the switching long wall, and the angle between the rotating part and the core-collecting auxiliary wall. Based on the situation that the inclination angles of the switching long wall, the switching long wall, the core-collecting auxiliary wall and the horizontal line remain unchanged, and by offsetting the rotating boss as close to the core-collecting side as possible, the angle between the rotating part and the switching long wall, and the angle between the rotating part and the core-collecting auxiliary wall can be increased as much as possible without adjusting other parameters, thereby increasing the fault tolerance rate and improving the overall effect and stability of the operation.

[0382] The core-collecting state is switched to the core-exiting state: by means of external force, while keeping the outer rod 1 stationary, the adjusting member 4 is moved to move the displacement member 41 from the core-collecting position A to above the core-exiting boss 713, and then the external force is released, and the displacement member 41 falls back under the influence of the reset member 3, contacts the core-exiting sliding wall 7131 and the control rod 21, and stays at the core-exiting position B.

[0383] In order to further improve the fault tolerance rate: the lower end point of the control switching wall 212 is higher than the upper end point of the core collecting auxiliary wall 717, which can achieve better effect.

[0384] In order to facilitate installation and maintenance, a cover body 14 is further provided on the outer rod, and the cover body 14 and the outer rod cooperate with each other.

[0385] In order to facilitate the installation of the adjustment component into the outer rod from bottom to top, the positioning member 7 needs to cooperate with the cover body 14. The present embodiment adopts a snap-fitting method, so the positioning member 7 is also provided with a snap-fitting portion 74; and the cover body 14 is provided with a cover body snap 141; and the cover body snap 141 is distributed in sections and is bent inward to a certain extent, so as to facilitate the snap-fitting portion 74 to be installed into the cover body 14; after the snap-fitting portion 74 is installed into the cover body 14, it is not easy to be pulled out.

[0386] In order to facilitate the auxiliary reset of the card holder, a reset ring 24 is also provided on the control member 2.

[0387] In order to minimize the negative impact of gravity on the rotating member, a rotation stabilizing boss 45 is provided on the adjusting member 4 , and a stabilizing abutting boss 451 is further provided on the rotation stabilizing boss 45 .

[0388] In order to facilitate manufacturing, such as rapid demolding of the mold, the above-mentioned rotating stabilizing boss 45 can be disassembled into separate accessories and re-fixed to the adjusting member 4, the outer rod 1 or the positioning member 7 by means of installation. The installation method can be fixed by snaps, glue, magnetism, screws or third-party tools.

[0389] In order to avoid unnecessary impact on the rotating member 82 during installation, an installation buffer groove 7D is provided in the positioning groove 71;

[0390] In order to better protect the rotating member 82 and the positioning groove, a positioning limit platform 7B is also provided on the above-mentioned positioning member 7, and a core-collecting error groove 7F is provided in the above-mentioned positioning groove 71; by limiting the positioning limit platform 7B and the displacement member 41, it is not necessary to limit the rotating member 82 and the positioning groove, so unnecessary interference between the rotating member 82 and the positioning groove should be avoided in the core-collecting state, and a larger error size can be provided through the core-collecting error groove 7F to ensure that there will be no impact on the rotating member 82 and the positioning groove in the core-collecting state.

[0391] Installation method:

[0392] First, assemble the positioning member, the rotating member and the adjusting member into an adjusting assembly. One end of the rotating member is sleeved on the rotating boss of the adjusting member. The positioning member is installed into a part of the adjusting member, and then the displacement part at the other end is installed into the positioning groove.

[0393] , the adjustment component is completed;

[0394] The cover 14 is installed into the outer rod from top to bottom, and the cover and the outer rod cooperate with each other.

[0395] Then install the auxiliary reset part, control part and adjustment assembly into the outer rod from bottom to top; fit the card part and the cover body on the positioning part into place; finally, install the tool body, reset part and pen changing part into the adjustment part from bottom to top in sequence, and then install the pen changing part and adjustment part into place.

[0396] The cover body 14 may also be installed last.

[0397] The core-out method adopts the third core-out method of pulling out: the external force controls the adjustment member 4 to move upward. When the displacement member 41 moves from the core receiving position A, it is affected by the core-out guide wall 7132 and enters the core-out channel B2. Then, it reaches the top of the core-out position B by switching the long wall 71B. At this time, release the external force and the displacement member 41 will fall back to the core-out position B.

[0398] There are three ways to collect the core:

[0399] 1. Move and control the core collection: the control member 2 is moved upward by external force, so that the displacement member 41 is free from the restriction of the control member 2, and the displacement member 41 is moved under the influence of the reset member 3, thereby realizing the core collection;

[0400] 2. Lifting and core collection scheme 1: External force controls the positioning member 4 to move upward, and through the core collection auxiliary wall 717 on the positioning groove 71, the displacement member 41 bypasses the restriction of the limiting boss 211 and is affected by the reset member 3 to fall back to the core collection position A.

[0401] Embodiment 5:

[0402] like Figures 24 to 25 The mechanical pen and the operating method thereof shown in the figure include an outer rod 1, a reset member 3, a tool body 5 and an adjustment module. The adjustment module includes a control member 2, an adjustment member 4 and a trigger assembly 6.

[0403] The control member 2 is provided with a control rod 21 .

[0404] The outer rod 1 is provided with a positioning groove 71 and a positioning portion 72. The positioning groove 71 is provided with a core-collecting switching wall 711, a core-collecting 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 thrust auxiliary slope 417. The tail of the tool body 5 is in conflict with the positioning portion 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.

[0405] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 moves in the positioning groove 71 .

[0406] The tool body 5 and the reset member 3 are placed in the adjusting member 4 , and the reset member 3 is 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 portion 72 .

[0407] The control member 2 and the adjustment member 4 are slidably sleeved in the outer rod 1:

[0408] The angle between the core collecting switching wall 711 and the core collecting limiting wall 712 forms a core collecting location A. The core discharging sliding wall 7131 is a core discharging location B.

[0409] The trigger assembly 6 is used to collect external trigger force and transmit it to the control member 2 , thereby controlling the movement of the control rod 21 .

[0410] The displacement member 41 is located at the core-retracting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-retracting state.

[0411] When the displacement member 41 is located at the core-out sliding wall 7131, it will be affected by the core-out sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-out sliding wall 7131. Before it completely leaves the core-out sliding wall 7131, it will be limited by the control rod 21 on the displacement member 41 and / or the adjustment member 4, so that the displacement member 41 cannot completely leave the core-out sliding wall 7131 normally. At this time, the core-out sliding wall 7131 determines the height position relationship of the displacement member 41. Finally, the displacement member 41 will stay on the core-out sliding wall 7131, and the position where the displacement member 41 stays at this time is the core-out position B. At this time, the writing part of the tool body 5 will expose the adjustment member 4, and it is in the core-out state.

[0412] At this time, the writing part of the tool body 5 will expose the adjusting member 4, which is the core-out state.

[0413] The control rod 21 can only move up and down or forward and backward relative to the positioning slot 71 , but cannot move left and right.

[0414] The above-mentioned displacement member 41 is also provided with a displacement protrusion 411 or a sliding bead groove, and the above-mentioned displacement member 41 itself does not produce the shape of the core A of the above-mentioned positioning groove 71, and 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.

[0415] The core-out boss 713 is provided with a core-out auxiliary slope B1 at the end near the core-collecting position A and / or the end near the core-out position B of the displacement member 41. The displacement member 41 itself has the ability to deform and bend forward and backward. When the displacement member 41 passes through the core-out boss 713, it can pass through the core-out auxiliary slope B1 and the deformation and bending ability of the displacement member 41 to cross the core-out boss 713 and reach the core-out position B. In this scheme, it is necessary to ensure that after the displacement member 41 reaches the core-out position B, it cannot use the deformation and bending ability to return to the core-collecting position A, such as adding a barb to the core-out boss 713, adding a rough texture, increasing the friction force and / or increasing the matching contact surface.

[0416] The trigger assembly 6 includes a limiter 61, a trigger ring 62 and a trigger cover 63. The limiter 61 passes through the trigger cover 63 and is connected to the control member 2, and the control member 2 moves with the limiter 61. The trigger cover 63 and the outer rod 1 are connected to each other, and the trigger cover 63 does not move relative to the outer rod 1. The trigger ring 62 is located between the limiter 61 and the trigger cover 63. A trigger auxiliary bevel ring C is provided on the lower side of the limiter 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 control member 2 can be moved upward relative to the positioning groove 71 through the trigger auxiliary bevel ring C, thereby moving the control rod 21 upward, so that the displacement member 21 slides from the core outlet B to the core collection A.

[0417] This embodiment can additionally realize reverse push to collect the core: keep the outer rod 1 stationary, pull the adjustment member 4 upward by external force, and through the reverse push auxiliary slope 417, the above-mentioned displacement member 41 is freed from the restriction of the core-exiting boss 713, so as to return to the core collection position A.

[0418] Installation method:

[0420] 2. Then install the adjusting part, tool body, reset part and pen changing part into the outer rod from bottom to top, and the pen changing part and adjusting part are matched;

[0421] 3. At this point, the installation is complete, and you can check whether the lower displacement boss 411 is located in the positioning groove 71. If not, adjust the position of the adjustment member to ensure that the displacement boss 411 is placed in the positioning groove 71.

[0422] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the entire pen should be erected before the core is ejected, which can ensure the success rate of core ejection. Of course, an auxiliary reset component can also be directly added between the control component and the trigger cover to improve the operating experience.

[0423] The core-out method adopts the second core-out scheme: keep the outer rod 1 stationary, and control the positioning member 4 to move upward with external force. When the displacement member 41 passes through the core-out boss 713, it passes through the core-out auxiliary slope B1 and the deformation and bending ability of the displacement member 41, and crosses the core-out boss 713 to reach the core-out position B;

[0424] There are two ways to collect the core:

[0425] 1. Triggering core collection scheme 1: The product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limiter 61, and the limiter 61 will move up, thereby driving the control member 2 to move up. When the control member 2 moves up, the displacement boss 411 loses the restriction of the control member 2 and slides down along the core-outlet sliding wall 7131 to the core collection position A. At this time, the tool body will be completely hidden in the pen-changing part D;

[0426] 2. Back-pushing core collection scheme 2: Keep the outer rod 1 stationary, and pull the adjustment member 4 downward by external force. Through the back-pushing auxiliary slope 417, the displacement member 41 is freed from the restriction of the core-exiting boss 713, and thus returns to the core collection position A.

[0437] The displacement member 41 is located at the core-retracting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-retracting state.

[0438] When the displacement member 41 is located at the core-out sliding wall 7131, it will be affected by the core-out sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-out sliding wall 7131. Before it completely leaves the core-out sliding wall 7131, it will be limited by the control rod 21 on the displacement member 41 and / or the adjustment member 4, so that the displacement member 41 cannot completely leave the core-out sliding wall 7131 normally. At this time, the core-out sliding wall 7131 determines the height position relationship of the displacement member 41. Finally, the displacement member 41 will stay on the core-out sliding wall 7131, and the position where the displacement member 41 stays at this time is the core-out position B. At this time, the writing part of the tool body 5 will expose the adjustment member 4, and it is in the core-out state.

[0445] Triggering scheme 1 indirectly controls the control member 2 to move upward through the trigger component 6. Triggering scheme 2 indirectly controls the control member 2 to move downward through the trigger component 6. The triggering scheme is mainly determined based on the direction in which the control member to be triggered needs to move.

[0446] Installation method:

[0447] 1. First, install the trigger cover, trigger ring and limiter into the outer rod from top to bottom in sequence. The limiter passes through the trigger ring, trigger cover and connector to cooperate.

[0459] The core collecting location A is formed at an angle between the core collecting switching wall 711 and the core collecting limiting wall 712 .

[0460] The displacement member 41 is located at the core-retracting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-retracting state.

[0461] When the displacement member 41 is located at the core-out sliding wall 7131, it will be affected by the core-out sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-out sliding wall 7131. Before it completely leaves the core-out sliding wall 7131, it will be limited by the control rod 21 on the positioning member 7, the displacement member 41 and / or the adjustment member 4, so that the displacement member 41 cannot completely leave the core-out sliding wall 7131 normally.

The trigger cover 63 and the outer rod 1 are connected to each other, and the trigger cover 63 does not move relative to the outer rod 1. The trigger ring 62 is located between the limiter 61 and the trigger cover 63. A trigger auxiliary bevel ring C is provided on the lower side of the limiter 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 control member 2 can be moved upward relative to the positioning groove 71 through the trigger auxiliary bevel ring C, thereby moving the control rod 21 upward, so that the displacement member 21 slides from the core outlet B to the core collection A.

[0469] In order to facilitate the loading of the sliding bead into the movable groove, a sliding bead loading groove is also provided on the above-mentioned positioning groove. The depth of the above-mentioned sliding bead loading groove is deeper than the other parts of the positioning groove. At the same time, a loading slope is also provided between the sliding bead loading groove and the other parts of the positioning groove. The above-mentioned loading slope is used to buffer the loading of the sliding bead and facilitate the transition of the sliding bead from the sliding bead loading groove into the positioning groove.

[0470] Installation method:

[0471] 1. First, assemble the positioning piece, sliding bead and adjusting piece into an adjusting assembly, insert the positioning piece into the adjusting piece, and then insert the sliding bead into the position slot and between the positioning slot and the movable slot through the sliding bead inserting slot; at this point, the adjusting assembly is completed;

[0472] 2. Then install the adjustment component into the outer rod from top to bottom. The adjustment component cannot be moved downward excessively due to the limit between the positioning piece and the outer rod. When the positioning piece stays at the installation position, the control piece, the auxiliary reset piece and the trigger cover body are installed into the outer rod from top to bottom in sequence;

[0473] 3. Then, place the trigger ring on the trigger cover, pass the limiter through the trigger ring and the trigger cover, and assemble it with the control part; then the whole assembly is roughly completed;

[0474] 4. Finally, install the tool body, reset part, and pen changer into the adjustment part from bottom to top, and then install the pen changer and adjustment part in place.

[0475] The core-out method adopts the core-out scheme 1: the external force controls the positioning member 4 to move upward, and through the switching long wall 71B on the positioning groove 71, it moves to between the core-out boss 713 and the control member 2, and stops at the core-out position B;

[0476] The core collecting method adopts trigger core collecting scheme 1: the product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limit member 61, and the limit member 61 will move up, thereby driving the control member 2 to move up. When the control member 2 moves up, the displacement part 821 loses the restriction of the control member 2 and will slide along the core outlet sliding wall 7131 to the core collecting position A. At this time, the tool body will be completely hidden in the pen changing part D.

[0477] Embodiment 8:

[0478] like Figures 33-36 A mechanical pen and its operation method are shown, comprising an outer rod 1, a reset member 3, a tool body 5 and an adjustment module. The adjustment module comprises a control member 2, an adjustment member 4, a trigger assembly 6 and a positioning member 7.

[0479] The control member 2 is provided with a control rod 21 .

[0480] The positioning member 7 is installed in the outer rod 1 and cannot move up and down significantly, and it is best not to move up and down. The positioning member 7 is provided with a positioning groove 71. The positioning groove 71 is provided with a core-collecting switching wall 711, a core-collecting limiting wall 712 and a core-exiting boss 713. The core-exiting boss 713 is provided with a core-exiting sliding wall 7131. The tail of the tool body 5 is in conflict with the positioning member 7, 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.

[0481] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 moves in the positioning groove 71 .

[0482] The tool body 5 and the reset member 3 are placed in the adjusting member 4, and the reset member 3 is 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.

[0483] The control member 2 and the adjustment member 4 are slidably sleeved in the outer rod 1:

[0484] The core collecting location A is formed at an angle between the core collecting switching wall 711 and the core collecting limiting wall 712 .

[0485] The displacement member 41 is located at the core-retracting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-retracting state.

[0486] When the displacement member 41 is located at the core-out sliding wall 7131, it will be affected by the core-out sliding wall 7131 and the reset member 3 and will move in the inclination direction of the core-out sliding wall 7131. Before it completely leaves the core-out sliding wall 7131, it will be limited by the control rod 21 on the positioning member 7, the displacement member 41 and / or the adjustment member 4, so that the displacement member 41 cannot completely leave the core-out sliding wall 7131 normally. At this time, the core-out sliding wall 7131 determines the height position relationship of the displacement member 41. Finally, the displacement member 41 will stay on the core-out sliding wall 7131, and the position where the displacement member 41 stays at this time is the core-out position B. At this time, the writing part of the tool body 5 will expose the adjustment member 4, and it is in the core-out state.

[0487] The trigger assembly 6 is used to collect external trigger force and transmit it to the control member 2, thereby controlling the movement of the control rod 21. When the control rod 21 is out of contact with the displacement member 41, the displacement member 41 will move from the core exit B to the core collection A.

[0488] The control rod 21 can only move up and down or forward and backward relative to the positioning member 7, but cannot move left and right.

[0489] The above-mentioned displacement member 41 is also provided with a rotating through hole 41F and a rotating fastener 4121. The above-mentioned rotating through hole 41F is also provided with a rotating member 82. The above-mentioned rotating member 82 is also provided with a rotating boss 412, a displacement portion 821 and three rotating contact bosses 82H. After the above-mentioned 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 portion 821. The above-mentioned displacement portion 821 directly contacts the positioning groove 71 instead of the displacement member 41; the above-mentioned rotating fastener 4121 is divided into a clamping portion 4131, a deformation notch 713K and a snap-in portion 4132. The above-mentioned rotating fastener 4121 is snapped into the side of the displacement member 41 through the snap-in portion 4132, and the displacement member 41 is also provided with a corresponding clamping slot 41Y. After the above-mentioned snap-in portion 4132 is snapped into the clamping slot 41Y, the clamping force is continuously applied to the rotating member 82 through the clamping portion 4131 and the deformation notch 713K, so that the rotating member 82 has a certain damping effect when rotating left and right, thereby overcoming the interference of gravity.

[0490] The rotating contact boss 82H can effectively reduce the friction between the rotating member 82 and the displacement member 41, thereby ensuring that the interference of gravity is overcome while having sensitive adjustable capabilities, thereby improving the actual operating experience.

[0491] A certain amount of space needs to be reserved at the rear side of the clamping portion 4131 to allow the clamping portion 4131 to deform backwards.

[0492] The present embodiment adopts a solution that the rotating boss is placed on the rotating member, and the rotating boss is arranged at a position higher than the displacement portion 821, which fully utilizes the internal space, reduces the overall length, and thus has a larger design space for the appearance, and can accommodate more refills. Also, because the main body of the displacement member 41 is installed at the middle side of the upper end, a rotating opening 4K is further provided between the displacement member 41 and the adjusting member 4, and the displacement portion 821 of the rotating member 82 enters the positioning groove 71 through the rotating opening 4K and moves.

[0493] The core-outlet boss 713 is also provided with a core-outlet guide wall 7132 on the side of the core-collecting position A. The positioning groove 71 is also provided with a core-outlet switching wall 714. A core-outlet channel B2 is also provided between the core-outlet switching wall 714 and the core-outlet boss 713. When the displacement member 41 moves upward from the core-collecting position A, it is affected by the core-outlet guide wall 7132 and enters the core-outlet channel B2, and then passes through the core-outlet switching wall 714 to reach the top of the core-outlet position B. At this time, if the external force is released, the displacement member 41 will fall back to the core-outlet position B.

[0494] The trigger assembly 6 includes a limiter 61, a trigger ring 62 and a trigger cover 63. The limiter 61 passes through the trigger cover 63 and is connected to the control member 2, and the control member 2 moves with the limiter 61. The trigger cover 63 and the outer rod 1 are connected to each other, and the trigger cover 63 does not move relative to the outer rod 1. The trigger ring 62 is located between the limiter 61 and the trigger cover 63. A trigger auxiliary bevel ring C is provided on the lower side of the limiter 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 control member 2 can be moved upward relative to the positioning groove 71 through the trigger auxiliary bevel ring C, thereby moving the control rod 21 upward, so that the displacement member 21 slides from the core outlet B to the core collection A.

[0495] The positioning groove 71 is provided with a multi-layer high-low misalignment design. A smooth slope D3 is provided between the bottom layer D2 and the top layer D1 of the multi-layer high-low misalignment design. For example, the area related to the core receiving part A forms the top layer, and the area related to the core outlet B forms the bottom layer, which is lower than the core receiving part A. Then, after the displacement member 41 enters the core outlet B from the core receiving part A, it is not easy to return to the core receiving part A by the original route, forming a loop similar to a one-way valve. The smooth slope can facilitate the displacement member 41 to return from the end of the bottom layer to the starting point of the top layer.

[0496] Installation method:

[0497] 1. First, assemble the positioning part, the rotating part and the adjusting part into an adjusting assembly. One end of the rotating part is sleeved on the rotating boss of the adjusting part. Insert the positioning part into the adjusting part, and then install the displacement part at the other end into the positioning groove. At this point, the adjusting assembly is completed.

[0498] 2. Then install the adjustment component into the outer rod from top to bottom. The adjustment component cannot be moved downward excessively due to the limit between the positioning piece and the outer rod. When the positioning piece stays at the installation position, continue to install the control piece and the trigger cover into the outer rod from top to bottom in sequence;

[0499] 3. Then, place the trigger ring on the trigger cover, pass the limiter through the trigger ring and the trigger cover, and assemble it with the control part; then the whole assembly is roughly completed;

[0500] 4. Finally, install the tool body, reset part, and pen changer into the adjustment part from bottom to top, and then install the pen changer and adjustment part in place.

[0501] This embodiment does not include an auxiliary reset component. Therefore, the control component needs to be reset by gravity. Before use, the entire pen should be erected before the core is ejected, which can ensure the success rate of core ejection. Of course, an auxiliary reset component can also be directly added between the control component and the trigger cover to improve the operating experience.

[0502] The core-out method adopts the core-out scheme 1: the external force controls the positioning member 4 to move upward, and through the switching long wall 71B on the positioning groove 71, it moves to between the core-out boss 713 and the control member 2, and stops at the core-out position B;

[0503] The core collecting method adopts trigger core collecting scheme 1: the product of the present invention is directly placed on a storage item such as a desktop, a school bag, a pencil case or a pocket, and the trigger ring 62 will be touched by the storage item. The force generated by the touch will be transmitted to the limit member 61, and the limit member 61 will move up, thereby driving the control member 2 to move up. When the control member 2 moves up, the displacement part 821 loses the restriction of the control member 2 and will slide along the core outlet sliding wall 7131 to the core collecting position A. At this time, the tool body will be completely hidden in the pen changing part D.

[0504] Embodiment 9:

[0505] like Figures 37-39 The tool shown includes an outer rod 1, a reset member 3, a tool body 5 and an adjustment member 4;

[0506] The outer rod 1 is provided with a core-out clamping platform 73, an inner moving groove 74 and a positioning portion 72;

[0507] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 moves between the core-outlet clamping platform 73 and the inner movable groove 74 ; the core-outlet clamping platform 73 and / or the displacement member 41 are also provided with a reverse thrust auxiliary slope 417 .

[0508] The control member 2 is provided with a release auxiliary slope 24 .

[0509] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 is movable between the core-exiting clamping platform 73 and the core-receiving clamping platform 74 .

[0510] The tool body 5 and the reset member 3 are placed in the adjusting member 4 , and the reset member 3 is 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 portion 72 .

[0511] The core receiving card platform 74 is a core receiving position A. The core output card platform 73 is a core output position B.

[0512] The trigger assembly 6 is used to collect external trigger force and transmit it to the control member 2 , thereby controlling the movement of the release auxiliary slope 24 .

[0513] The control member 2 and the adjustment member 4 are slidably sleeved in the outer rod 1:

[0514] The displacement member 41 is located at the core-retracting position A. At this time, the tool body 5 remains completely hidden inside the adjusting member 4, which is in the core-retracting state.

[0515] When the displacement member 41 is located at the core-out position B, the writing portion of the tool body 5 will expose the adjustment member 4, which is the core-out state.

[0516] The trigger assembly 6 includes a trigger member 64, a trigger ring 62 and a rotating fixture 65. The trigger member 64 passes through the rotating fixture 65 and the trigger ring 62 to be connected to each other. The rotating fixture 65 is fixed to the top of the outer rod 1. A rotating ring protrusion 641 is provided at the middle end of the trigger member 64, and a trigger ring protrusion 642 is provided at the lower end of the trigger member 64. The trigger member 64 can be tilted and / or moved downward 360 degrees relative to the rotating fixture 65 through the rotating ring protrusion 641. The rotating ring protrusion 641 cannot pass through the rotating fixture 65. A downward moving ring protrusion 22 is provided at the top of the control member 2. When the trigger ring protrusion 642 moves toward the middle, it will squeeze the downward moving ring protrusion 22, indirectly prompting the release auxiliary slope 24 to move downward. The downward movement of the release auxiliary slope 24 will cause the displacement member 41 to be out of cooperation with the core-out card platform 73, and thus fall back to the core-collecting card platform 74 under the influence of the reset member 3.

[0517] The trigger ring protrusion 642 directly contacts the control member 2. When the trigger member 64 rotates and / or moves downward, the control member 2 will move downward. When the control member 2 moves downward, the displacement member 41 will be controlled to move inward by releasing the auxiliary slope 24, thereby eliminating the matching relationship between the displacement member 41 and the core ejection card platform 73.

[0518] When the adjusting member 4 is installed into the outer rod 1 and the displacement member 41 enters the upper part of the core collecting boss 74 , it is restricted by the core collecting boss 74 and is not easy to be separated.

[0519] The reset member 3 and the auxiliary reset member 31 of this embodiment use the repulsive force between magnets to replace the spring solution in other embodiments.

[0520] This embodiment can also realize reverse push core collection: keep the outer rod 1 stationary, pull the adjustment member 4 downward by external force, and through the reverse push auxiliary slope 417, the displacement member 41 is freed from the restriction of the core output clamping platform 73, so as to return to the core collection position A.

[0521] Installation method:

[0522] 1. First, install the auxiliary reset part, control part, trigger part and rotating fixture into the outer rod from top to bottom, and match the rotating fixture with the outer rod;

[0523] 2. Then install the adjustment piece into the outer rod from bottom to top, and the displacement piece enters the inner moving groove to form a snap fit. At this time, the adjustment piece is not easy to separate from the outer rod;

[0524] 3. Install the tool body, reset part and pen-changing part into the adjusting rod in sequence, and match the pen-changing part with the adjusting rod.

[0525] 4. Finally, match the trigger ring and the trigger part together.

[0526] The core-out method adopts the fourth core-out method: Under the premise of keeping the outer rod 1 stationary, the adjusting member 4 is moved toward the trigger assembly end by external force, so that the displacement member 41 moves from the core receiving card platform 74 to the core-out card platform 73, and then the external force is released. Under the action of the reset member 3, the displacement member 41 will be engaged with the core-out card platform 73, thereby maintaining the core-out state.

[0527] There are three ways to collect the core:

[0528] 1. Pressing and core-collecting scheme 3: Pressing the trigger ring 62 by external force makes the trigger ring 62 squeeze the trigger cover 63 or the trigger member 64, so that the trigger cover 63 or the trigger member 64 squeezes the control member 2, and the control member 2 makes the displacement member 41 move inward, so that the displacement member 41 and the core-discharging clamping platform 73 are disengaged, and the displacement member 41 returns to the core-collecting position A through the reset member 3;

[0529] 2. Reverse push core collection scheme 1: Keep the outer rod 1 stationary, and pull the adjustment member 4 downward by external force. Through the reverse push auxiliary slope 417, the displacement member 41 is freed from the restriction of the core output clamping platform 73, and thus returns to the core collection position A;

[0530] 3. Trigger core collection scheme 2: Place the product of the present invention directly on a storage item such as a desktop, school bag, pencil case or pocket, then the trigger ring 62 will be touched by the storage item, and the force generated by the touch will be transmitted to the trigger ring 62, and the trigger ring 62 will tilt, causing the control member 2 to move downward. When the control member 2 moves downward, the control member 2 causes the displacement member 41 and the core output card platform 73 to be disengaged, so that the displacement 41 will be affected by the reset member 3 and slide to the core collection position A. At this time, the tool body will be completely hidden in the pen changing part D.

[0544] In order to better contact and cooperate with the push rod, the displacement member 41 is further provided with a displacement locking protrusion 411 .

[0545] Installation method:

[0546] 1. First, install the auxiliary reset part, control part, trigger part and rotating fixture into the outer rod from top to bottom, and match the rotating fixture with the outer rod;

[0547] 2. Then install the adjustment piece into the outer rod from bottom to top, and the displacement piece enters the inner moving groove to form a snap fit. At this time, the adjustment piece is not easy to separate from the outer rod;

[0548] 3. Install the tool body, reset part and pen-changing part into the adjusting rod in sequence, and match the pen-changing part with the adjusting rod.

[0549] The core-out method adopts the fourth core-out scheme: the external force controls the positioning member 4 to move upward, and the displacement member 41 moves directly from the core receiving position A to the core-out clamping platform 73, and forms a clamping engagement with the core-out clamping platform 73, and the core-out is completed;

[0550] At the same time, it has the following four core collection methods:

[0551] 1. Pressing and core-collecting scheme 3: Pressing the trigger ring 62 by external force makes the trigger ring 62 squeeze the trigger cover 63 or the trigger member 64, so that the trigger cover 63 or the trigger member 64 squeezes the control member 2, and the control member 2 makes the displacement member 41 move inward, so that the displacement member 41 and the core-discharging clamping platform 73 are disengaged, and the displacement member 41 returns to the core-collecting position A through the reset member 3;

When the deformation reaches a certain degree, the hand is released, and the elastic force of the reset member 3 makes the speed of the displacement member 41 falling back greater than the speed of the displacement member 41 restoring the deformation.

[0612] Core collection method:

[0613] 1. Press rod core collection scheme 1: External force squeezes the press rod 75 to contact one end of the displacement member 41, so that the press rod 75 squeezes the displacement member 41 away from the core output card platform 73; when the displacement member 41 is separated from the core output card platform 73, it is affected by the reset member 3 and moves downward to the core collection position A.

[0614] 2. Pressing rod core collection scheme 2: external force lifts the pressing rod 75 away from one end of the displacement member 41, so that the other end of the pressing rod 75 is affected by linkage to squeeze the displacement member 41 out of the core output card platform 73; when the displacement member 41 is out of the core output card platform 73, it is affected by the reset member 3, and the displacement member 41 moves down to the core collection position A;

By not using the switching slope 76, the displacement member 41 is further deformed backward. When the deformation reaches a certain degree, the user lets go. Then, through the elastic force of the reset member 3, the speed at which the displacement member 41 falls back is greater than the speed at which the displacement member 41 recovers its deformation. Then, when the displacement member 41 passes through the core-exiting clamping platform 73, it will not be re-stuck in the core-exiting clamping platform 73, but will fall back to the bottom, that is, the limit position of the core-collecting.

[0628] In order to better contact and cooperate with the push rod, the displacement member 41 is further provided with a displacement locking protrusion 411 .

[0629] Installation method:

[0630] 1. First, install the adjustment piece into the outer rod from bottom to top, and the displacement piece enters the inner moving groove to form a snap fit. At this time, the adjustment piece is not easy to separate from the outer rod;

[0631] 2. Install the push rod 75 at the tail of the outer rod 1;

[0632] 3. Finally, install the tool body, reset part and pen-changing part into the adjusting rod in sequence, and match the pen-changing part with the adjusting rod.

[0633] The core-out method adopts the core-out pulling scheme five: the external force controls the adjustment member 4 to move upward, and the displacement member 41 moves upward from the core receiving position A, reaches the core-out card platform 73 through the extended switching slope 415 and / or the blocking entry slope 171, and forms a card engagement with the core-out card platform 73, and the core-out is completed.

[0634] The core collection method uses the following two methods at the same time:

[0635] 1. Press rod core collection scheme 1: External force squeezes the press rod 75 to contact one end of the displacement member 41, so that the press rod 75 squeezes the displacement member 41 away from the core output card platform 73; when the displacement member 41 is separated from the core output card platform 73, it is affected by the reset member 3 and moves downward to the core collection position A.

[0636] 3. Lifting and core collection scheme three: external force controls the adjustment member 4 to move upward, and by not using the switching slope 76, the displacement member 41 is deformed backward. When the deformation reaches a certain degree, the external force is released. Under the influence of the reset member 3, the displacement member 41 will pass through the core output card platform 73, but will not cooperate with the core output card platform 73, but will directly fall into the core collection position A.

[0637] Embodiment 15:

[0645] The positioning groove 71 is also provided with a core-out limiting wall 716 and a core-in auxiliary wall 717 .

[0646] An auxiliary reset member 31 is provided between the control member 2 and the positioning member 7.

[0647] The displacement member 41 is further provided with a rotation abutment boss 413 for abutting against the adjustment rotation member 82 .

[0648] A core collection switching wall 711 is provided in the positioning groove 71; because the position of the core collection switching wall 711 is the falling position and the longest stroke area, the slope requirement is relatively low and it is very easy to fall back. This long-distance movement will have more variables for the core-out process. Therefore, the core collection location A is changed to be directly below or directly above the core-out boss 713 through the core collection switching wall 211, which is conducive to the stability of the core collection switching when the core is switched out.

[0649] The positioning member 7 is also provided with a control groove 715 for accommodating the up and down movement of the control rod 21;

[0650] The positioning groove 71 is also provided with an anti-slip boss 719, and a fall-back channel 71A is also provided between the limiting boss 211 and the anti-slip boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211;

[0654] The adjusting member 4 is provided with a rotating stabilizing boss 45; the displacement member 41 is also provided with a rotating abutting boss 413 for abutting against the adjusting rotating member 82;

[0655] Installation method:

[0656] 1. Assemble the adjusting part, rotating part and positioning part into an adjusting assembly, and then install them into the outer rod from top to bottom;

[0657] 2. Then, install the auxiliary reset part, the control part, the cover body, the trigger cover body, the trigger ring, and the limit rod into the outer rod in sequence from top to bottom; the cover body and the outer rod are threadedly matched, and the limit part and the connector on the cover body are threadedly matched for the second time;

[0658] 3. Pass the side pusher through the side of the outer rod and directly snap it into the adjustment piece.

[0659] 4. Finally, install the tool body, reset part, pen grip T and pen changer into the adjustment rod in sequence, and match the pen changer with the outer rod.

[0660] The core-out method adopts the side-pushing core scheme three: the external force controls the downward movement of the adjustment member 4 through the side pushing part, and the above-mentioned displacement member 41 moves downward from the core receiving position A, and enters the core-out channel B2 through the influence of the core-out guide wall 7132, and then reaches the top of the core-out position B by switching the long wall 71B. At this time, release the external force, and the displacement member 41 will fall back to the core-out position B, and the core-out is completed.

[0661] The following two methods are used at the same time:

[0662] 1. Side-push core collection scheme 1: The external force side-push part 1A controls the adjustment member 4 to move further downward, and the displacement member 41 will continue to move downward, and then pass through the core collection auxiliary wall 717 on the positioning groove 71, so that the displacement member 41 bypasses the restriction of the limiting boss 211, and returns to the core collection position A through the rebound force of the reset member 3.

[0663] 2. Trigger core collection scheme 1: The external forces around are collected by the trigger ring, and the force collected by the trigger ring is transmitted to the control part through the trigger cover, thereby causing the control part 2 to move, so that the displacement part 41 is free from the restriction of the control part 2, and the displacement part 41 will be affected by the reset part 3 to move, thereby realizing the core collection.

[0664] The core-out scheme adopted in the present embodiment is special in that, compared with the previous embodiments, the positioning member is operated neither through the tail end nor through the front end, but is operated from the side with the assistance of a side pusher, and the side pusher can be realized by integrally forming with the adjusting member or in the form of a separate accessory. When integrally formed, the side pusher needs to be deformed backward relative to the positioning member to facilitate installation, while the present embodiment adopts the form of a separate accessory snap-in.

[0665] Embodiment 16:

[0666] like Figures 54-58 The mechanical pen and the operating method thereof include an outer rod 1, a reset member 3, a tool body 5, a control member 2, an adjustment member 4 and a positioning member 7;

[0667] The positioning member 7 is provided with a positioning groove 71;

[0668] The adjusting member 4 is provided with a displacement member 41 , and the displacement member 41 is movable in the positioning groove 71 .

[0669] The outer rod 1 is also provided with a pressing groove 1B; a side pressing piece 1B1 is also provided in the pressing groove 1B, and the positioning member 4 is provided with a core pressing auxiliary slope 1B2 used in conjunction with the side pressing piece 1B1; the side pressing piece 1B1 moves forward and backward relative to the pressing groove 1B, and when the side pressing piece 1B1 moves backward, it squeezes the core pressing auxiliary slope 1B2, thereby causing the positioning member 4 to move downward, and pressing the side pressing piece 1B1 to the bottom will cause the displacement member 41 to move from the core receiving portion to the core receiving portion. The side press piece 1B1 moves from point A to point B for core exiting; the conversion ratio between the pressing stroke of the side press piece 1B1 and the downward movement of the adjusting piece 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 piece 1B1 and the downward movement of the adjusting piece 4, and the side press piece moves a shorter distance, which can ensure that the adjusting piece moves a greater distance, thereby meeting the minimum requirement for the core exiting displacement of the adjusting piece.

[0670] The side pressing piece 1B1 is provided with an auxiliary insertion protrusion 1B2, and the pressing groove 1B is also provided with an auxiliary insertion groove 1B3 that matches the auxiliary insertion protrusion 1B4; when the side pressing piece 1B1 is pressed to the bottom, the adjusting piece 4 moves down to the position, so that the core is ejected normally. At this time, because the position of the adjusting piece 4 has reached a core-ejecting fixed state through the resetting piece 3 and the positioning piece, the adjusting piece 4 will not apply a resetting force to the side pressing piece 1B1 at this time, and the side pressing piece 1B1 will shake back and forth at this time, which will affect the writing process of the core-ejecting state. , causing unnecessary interference. Therefore, adding the auxiliary insertion protrusion 1B4 and the auxiliary insertion groove 1B3 can ensure that after the side press piece 1B1 is pressed to the bottom, the side press piece 1B1 will be temporarily fixed with the outer rod 1 while the adjusting piece 4 controls the core output. This temporary fixation is not reliable. When the automatic core collection is triggered, the side press piece 1B1 will be reset due to the force applied by the resetting piece 3 to the adjusting piece 4, and the core output pressing auxiliary slope 1B2 will prompt the side press piece 1B1 to break away from the temporary fixation, reset, and wait for the next use.

[0671] When the side core is pushed out or the side core is pressed out, the tail end of the tool body does not conflict with the positioning member, but conflicts with the adjustment member, and the auxiliary reset member is also changed to be arranged between the control member and the positioning member.

[0672] The outer rod 1 is also provided with a trigger assembly 6 .

[0673] The outer rod 1 is provided with a cover body 14, and the cover body 14 is provided with a connector 11; the trigger assembly 6 includes a limiter 61, a trigger ring 62 and a trigger cover body 63; the limiter 61 passes through the trigger cover body 63 and is connected to the connector 11, and the trigger cover body 63 passes through the connector 11 and is connected to or in contact with the control member 2; when the trigger cover body 63 moves downward, the control member 2 will also be pressed to move downward; the trigger ring 62 is located between the limiter 61 and the trigger cover body 63; a trigger auxiliary oblique ring C is provided on the lower side of the limiter 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 body 63;

[0675] The positioning groove 71 is also provided with a core-out limiting wall 716 and a core-in auxiliary wall 717 .

[0676] An auxiliary resetting member 31 is provided between the control member 2 and the positioning member 7 .

[0677] The displacement member 41 is further provided with a rotation abutment boss 413 for abutting against the adjustment rotation member 82 .

[0678] A core collection switching wall 711 is provided in the positioning groove 71; because the position of the core collection switching wall 711 is the falling position and is also the area with the longest stroke, the requirement for the slope is relatively low and it is very easy to fall back. This long-distance movement will have more variables for the core output process. Therefore, the core collection position A is changed to be directly below or directly above the core output boss 713 through the core collection switching wall 211, which is helpful for the stability of the core collection and core output switching.

[0679] The positioning member 7 is also provided with a control groove 715 for accommodating the up and down movement of the control rod 21;

[0680] The positioning groove 71 is also provided with an anti-slip boss 719, and a fall-back channel 71A is also provided between the limiting boss 211 and the anti-slip boss 719 or between the inner wall of the outer rod 1 and the limiting boss 211;

[0681] The adjusting member 4 is further provided with an adjusting abutment portion 42 ; the rear end of the tool body 5 abuts against the adjusting abutment portion 42 .

[0682] The rotating part is also provided with a rotating auxiliary platform and / or a rotating installation cutout. A conflict is generated between the rotating auxiliary platform and the displacement part and / or between the rotating interference bosses. The rotating auxiliary platform can effectively help the rotating part to offset the interference of gravity. The rotating installation cutout can be used when the rotating boss is integrated between the rotating auxiliary platform and the displacement part. At this time, when the rotating part is difficult to install, the rotating part can be quickly, effectively and stably installed in place through the rotating installation cutout.

[0683] The adjusting member 4 is provided with a rotational stabilizing boss 45; the displacement member 41 is also provided with a rotational abutting boss 413 for abutting against the adjusting rotating member 82, and the rotating member 82 is also provided with a rotational auxiliary platform 822 and / or a rotational mounting notch 823

[0684] The core-outlet boss 713 may be provided with a deformation notch 713K. The upper and lower sides of the core-outlet boss 713 only need one side and both sides to have a deformation notch 713K. In this way, the core-outlet boss 713 has a deformation capability, and the displacement member 41 can also pass over the core-outlet boss 713 without the need for a deformation capability.

[0685] Installation method:

[0686] 3. The adjusting part, rotating part and positioning part are assembled into an adjusting assembly, and then installed into the outer rod from top to bottom;

[0689] 4. Finally, install the tool body, reset part, pen grip T and pen changer into the adjustment rod in sequence, and match the pen changer with the outer rod.

[0690] The core-out method adopts the second side-press core-out scheme: the side-pressing member 1B1 is controlled by external force to move backward, and the positioning member 4 will move downward with the displacement member 41, so that when the displacement member 41 passes through the core-out boss 713 and the core-out auxiliary slope B1 and / or the deformation and bending ability of the displacement member 41, it crosses the core-out boss 713 and reaches the core-out point B, then the core-out is completed.

[0691] The core collection method adopts trigger core collection scheme 1: the external force around is collected by the trigger ring, and the force collected by the trigger ring is transmitted to the control part through the trigger cover, thereby causing the control part 2 to move, so that the displacement part 41 is free from the restriction of the control part 2, and the displacement part 41 will be affected by the reset part 3 to move, thereby realizing the core collection.

[0692] The core-out scheme adopted in this embodiment is special in that, compared with the previous embodiments, the positioning member is neither operated through the tail end nor through the front end, but is operated from the side with the assistance of the side pressing part, providing a new core-out operation mode, and also taking into account the optimal core-collecting mode of triggering the core collection.

[0693] The rotating part of the present embodiment is installed by side clipping, because the rotating boss of the present embodiment is formed integrally between the rotating stabilizing boss 45 and the displacement member 41. Therefore, the rotating part 82 cannot be installed into the rotating boss by front-to-back insertion. Therefore, the rotating boss is installed by side clipping.

[0694] The above embodiments 1 to 8, 15 and 16 all have additional supplementary points:

[0695] 1. The surfaces of the control rod 21 and the trigger ring should be as smooth as possible to reduce friction, thereby reducing the force required for triggering and further improving the triggering effect.

[0696] 2. In order to facilitate the cooperation with the auxiliary fall slope 213 in the above-mentioned embodiments 2 and 3, a corresponding small fall slope 7133 is provided on the above-mentioned core-outlet boss 713. 3. The slope area of ​​the above-mentioned small fall slope 7133 is small, which will not cause the core-outlet boss 713 to be unable to effectively cooperate with the displacement member 41.

[0697] 4. In order to facilitate better cooperation with the core-out auxiliary slope B1, the core-out boss 713 is provided with a corresponding core-out small slope 7134. The slope area of ​​the core-out small slope 7134 is small and will not affect the cooperation between the displacement member 41 and the switching long wall 71B.

[0698] 5. In order 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-collecting 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-collecting limiting wall 712 or the inner wall of the outer rod 1 is equal to the function of the core-collecting limiting wall 712, which plays a limiting role.

[0699] 6. The outer diameter of the trigger ring 62 is greater than the outer diameter of the outer rod 1. The lower end of the control member 2 may also be extended with an extension rod 23. A trigger slope 621 is added to the lower end of the trigger ring 62. The extension rod 23 can enrich the internal structure, prevent the adjustment member 4 from shaking and / or detaching from the outer rod 1, and prevent the control member 2 from shaking and rotating unnecessarily. It can also provide a limit for the control member 2, so as to better stabilize the internal structure. The inclination angle of the trigger slope is determined by the set trigger inclination angle. For example, when the inclination is 10°, the trigger core can be retracted, and the inclination angle of the slope is more than 10°, which is convenient for improving the trigger effect.

[0700] 7. The inner diameter of the core-discharging card platform 73 is reduced inwardly, so that the inner diameter of the core-discharging card platform 73 is smaller than the outer diameter of the core-collecting card platform 74. A card platform switching slope 731 is provided at the lower side of the core-discharging card platform 73.

[0701] The above embodiments 1 to 16 all have additional supplementary points:

[0702] 1. In order to facilitate the replacement and installation of the refill, the front end of the adjusting member or the outer rod can be disassembled into a refill part D.

[0703] 2. The tool body 5 is itself an internally contained tool, which is the basis of writing. However, there are many writing media, and their external structural shapes can be relatively unified. Therefore, the tool body includes ballpoint pen refills, gel pen refills, fountain pen writing refills and ink sacs, highlighter pen refills, rollerball pen refills, erasable pen refills, eyebrow pencils, screwdrivers, keys, hand knives, lipsticks, eternal pen refills and / or pencil refills.

[0704] 3. The essence of the above-mentioned reset member 3 is to provide a continuous force, so the above-mentioned reset member 3 and the auxiliary reset member 31 are elastic materials, magnetically absorbable objects, magnetically absorbable materials, elastic materials and / or reset springs in combination or formed separately.

[0705] 4. The elastic force of the auxiliary restoring member 31 is smaller than the elastic force of the restoring member 3 .

[0706] Special additional instructions:

[0707] 1. In the embodiment: "The control rod 21 can only move up and down or forward and backward relative to the positioning slot 71, and cannot move left and right." This is based on the actual situation in the embodiment. For the sake of stability during writing, it does not mean that it must be designed in this way. It is also possible to adopt a movement method of obliquely upward, obliquely downward, obliquely forward, obliquely backward, leftward and rightward. However, the operating experience will be worse, and an additional guide structure matching the operating orientation needs to be designed in the internal structure. Moreover, when the adjustment member is kept stationary, the positioning member needs to be rotatable. In this case, the positioning member 7 can rotate relative to the outer rod. Therefore, the solution in which the positioning member can rotate also falls within the protection scope of the present invention.

[0708] 2. Regarding the positional relationship between the control member 2, the adjustment member 4, the positioning member 7, and the trigger assembly, since these components have great extensibility and may undergo many changes, there are many possibilities for positional relationship combinations. There is no absolute positional relationship, and the main purpose is to realize the operating method and design concept expressed by the present invention.

[0709] 3. The design of the adjustment member 4 being difficult to separate after being installed in the outer rod 1 can be realized in many ways, such as the positioning groove 71, the positioning part 72, the positioning member 7 and / or the control member 2 structure itself limiting the position thereof and the derivative parts of these limiting the adjustment member 4. This method belongs to the technical personnel in the field, so similar problems are not described in detail. For example, in embodiment 1, the rotating member 82 is used to be inserted between the rotating boss on the displacement member 41 and the positioning groove 71 to ensure that the adjustment member 4 is separated from the outer rod 1.

[0710] 4. When the displacement member 41 is deformed, a certain deformation space needs to be reserved in the internal space for the displacement member 41. Such reservation of deformation for the displacement member can be based on actual conditions. Such a method can help those skilled in the art to solve the problem of backward movement caused by deformation. For example, in Example 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 boss 411 passes through the core output boss 713.

[0711] 5. As to the problem of preventing the control rod 21 from moving left and right, relevant convex blocks are set on the outer rod, and corresponding convex blocks are also set on the control rod 21, so as to prevent rotation. As to the maximum upper limit and the maximum lower limit of the control rod 21, it is only necessary to set relevant convex blocks inside the outer rod, so the specific positions of the maximum upper limit and the maximum lower limit can be determined according to the actual situation.

[0712] 6. When the control member 2 is released by moving upward, the control member 2 and the trigger assembly 6 can be used normally even without the auxiliary reset member 31. The gravity of the control member 2 can be used to reset the control member 2 downward. It is necessary to ensure that the friction of the part of the outer rod 1 related to the sliding of the control member 2 is small, and the control member 2 itself has a certain gravity, so the effect will be better. In order to make the operation more stable, it is better to use the auxiliary reset member 31. The elastic force of the auxiliary reset member 31 does not need to be too large, as long as it can reset the control member 2.

[0713] 7. There are two ways to pull out the core, and they can exist at the same time as the triggering of the core collection. When the internal structure is used for implementation, the solution of embodiment 1 is better, and when it needs to be exposed to consumers, the method of embodiment 3 can be used. When it is necessary to press the core out, embodiment 2 can be used. Of course, there are many specific combinations, and there are still details that can be optimized. However, several modifications and improvements made without departing from the design concept and principle of the present invention should also be regarded as the scope of protection of the present invention.

[0714] 8. In the description of the present invention, there are many concepts about positional relationships, and the same component also contains multiple positional relationships. It should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on different embodiments and orientations or positional relationships shown in different drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0715] 9. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a communication between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0716] 10. The positioning groove 71 includes not only the above-mentioned channels, for example, there is also a core-collecting and falling channel between the core-exiting boss 713 and the core-collecting switching wall 711. Such normalized channels will not be specifically described. What needs to be understood is that the channels in the positioning groove are configured by default to allow the displacement member 41 and its related deformation components to pass through.

[0717] 11. The related structures of the trigger components in the present invention are only exemplary structures of the present invention, and related structures that can achieve similar effects should also be regarded as within the protection scope of the present invention.

[0718] 12. The conflicting position of the pen core is also determined according to the actual needs of the structure. For example, in Example 1, the pen core conflicts with the bottom of the positioning member, while in Example 2, it conflicts with the adjusting conflicting portion 42 of the adjusting member, and in Example 3, it conflicts with the positioning portion 72.

[0719] 13. When the "trigger assembly" is not used and the control rod is operated alone, a component similar to the trigger cover 63 must be added to the outer rod to cooperate with the outer rod. This component similar to the trigger cover 63 can be integrated with the outer rod, so it does not need to be explained separately. A through hole is also provided in the middle of this component similar to the trigger cover 63. The above-mentioned control rod only needs to expose the through hole and be able to be touched by a person, as shown in Example 4.

[0720] 14. Regarding the angle between the core-collecting switching wall 711, the switching long wall 71B, the switching long wall 71B, the core-collecting limiting wall 712, the core-discharging sliding wall 7131, the control switching wall 212, the core-collecting auxiliary wall 717 and / or the core-discharging guide wall 7132 and the horizontal line, the angle is generally between 15° and 80°, and the core-collecting limiting wall 712 can be 90° or other degrees; generally speaking, a degree near 45° is more ideal, such as: 50°, 40°, 55°, 60°, 58°, 42°, 35° and / or 65° and so on will be more appropriate, and the specific angle limit is mainly determined by the core-discharging stroke and the core-collecting stroke of the pen, because the size of the angle will The vertical distance between the two end points of the wall determines the passing efficiency of the displacement member 41, and this vertical distance will directly affect the core-out stroke and the core-retracting stroke of the pen; therefore, the angle depends on whether the actual tool body itself is a fountain pen, pencil, gel pen or ballpoint pen, because each tool body requires the core-out stroke and core-retracting stroke, and the passing efficiency of the displacement member 41 will also change when facing different walls. Therefore, the size of the angle between all the above-mentioned walls and the horizontal line depends on the actual situation, so as to ensure that the displacement member 41 can pass smoothly during the entire operation while satisfying the core-out stroke and core-retracting stroke required by the tool body.

[0721] 15. The inventive concept of the present invention can be applied not only to the field of pen making, but also to the exposure and storage of the use parts of other small tools.

[0722] 16. Considering the convenience of practical operation, the operation method of the present invention is to keep the outer rod still and move the adjusting part or the positioning part to carry out the core extraction and collection. This is because the outer rod has the largest exposed area and is the easiest to fix. When using it, it can generally be clamped directly with the base of the palm. Conversely, keeping the adjusting part and the positioning part still and moving the outer rod to control the core extraction and collection is also possible.

[0723] 17. The order of installing components will be different in each embodiment, depending on the structure of the outer rod and whether a positioning member, a trigger assembly, etc. are used. Generally speaking, after the outer rod is added with a pen-changing part, no matter how the supporting structure of the upper part of the outer rod is installed, the tool body and the reset member are installed into the outer rod from bottom to top, and then the pen-changing part is installed. Of course, according to actual conditions, it is also possible to install from top to bottom. However, since most of the core structure is in the space at the tail, the bottom-up installation method is more suitable for replacing the tool body.

[0724] 18. Some structures can also be added to prevent the positioning member from rotating, such as adding an anti-rotation boss 13 to limit the positioning member from rotating left and right.

[0725] 19. After the positioning piece is installed, the positioning piece can be prevented from moving up and down by triggering the limit of the cover body and the limit ring 12 or the limit of the outer rod itself, thereby ensuring the accuracy of the operation.

[0726] 20. Regarding the length and positional relationship of the core-collecting switching wall 711, the core-collecting auxiliary wall 717, the switching long wall 71B, the switching long wall 71B, the core-collecting limiting wall 712, the core-outlet sliding wall 7131, the control switching wall 212 and / or the core-outlet guiding wall 7132 in the positioning groove, the main purpose is to ensure the efficiency and fault tolerance of the displacement member 41 passing through; for example, the horizontal distance between the end point of the core-outlet sliding wall 7131 close to the core-outlet B and the end point of the core-outlet limiting wall 716 close to the core-outlet sliding wall 7131 should be greater than the width of the displacement member, so as to ensure that the displacement member moves up or down. During the displacement process, it can stably contact the core-collecting auxiliary wall 717; the straight-line distance between the end point of the core-outlet sliding wall 7131 away from the core-outlet 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-outlet sliding wall 7131 away from the core-outlet point B and the end point of the core-outlet limiting wall 716 close to the core-outlet 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-outlet sliding wall 7131 during the process of moving up or down; and so on.

[0727] 21. In order to facilitate the replacement of the tool body, the front end of the outer rod can also be disassembled into the pen-changing part. If the outer rod is selected to be disassembled into the pen-changing part, then under normal circumstances, the adjusting part does not need to be disassembled into the pen-changing part, especially when the core is pressed out. At this time, the adjusting part is located inside the outer rod and is also responsible for resisting the tool body. Therefore, if the pen-changing part cannot be provided, it is more appropriate to disassemble it from the outer rod.

[0728] 22. Fitting instructions: Most parts can be matched with each other by means of threads, snap-fit, magnetism, adhesives, sockets and / or third-party accessories. Other new materials or technologies can also be used, such as welding, elastic object-assisted snap-fit, etc.

[0729] 23. There are many possibilities for the position of the above-mentioned adjustment hole, because the structural concept of the present invention is relatively flexible and is not limited to a certain scheme. As shown in Examples 1 to 4, the parts that the tail of the tool body contacts are 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; and the inventive concept of the adjustment hole and the adjustable base can also be applied to other similar products.

[0730] 24. The adjustable base requires a certain length of travel to provide ample space. When the adjustment hole is not large enough, a certain amount of space can be made available through the structure behind the adjustment hole. The structure behind the adjustment hole needs to provide sufficient adjustment through holes to facilitate the length adjustment of the adjustable base. For example, the positioning member in Example 3 provides the adjustable base with ample length space and also provides threaded fit to further improve stability.

[0731] 25. The length of the external adjustment tool is customized according to actual needs, so the scale lines of the commonly used length specifications are also customized according to actual needs. For example, in the field of pen refills, the commonly used specifications are G2 and G5. There are only two scale lines on the external adjustment tool, G2 and G5, and the scale lines of G2 and G5 on the external adjustment tool are not just the actual length dimensions of the original pen refills G2 and G5; because when using the external adjustment tool, the pen changing part is in a state of being separated from the outer rod or the adjustment part, then the internal space of the outer rod or the adjustment part at this time cannot completely accommodate the pen refill, then the part that the external adjustment tool scale line needs to refer to also becomes the bottom end of the outer rod or the adjustment part, then the length of the pen changing part should be deducted, and the internal structure state during adjustment needs to be unified, such as the state of the refill or the displacement part. 41 When it is pushed upward to the top of the positioning groove, the adjustment is performed, and the length of the scale line on the external adjustment tool should be the length of the required specification 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, such as: the pen core is installed in the outer rod and the pen changing part in the normal standard, and the core-out state is used as the unified internal structure state during adjustment. In the core-out state, it is necessary to keep the pen core exposed for a certain stroke, then the error length is equal to the exposed stroke of the pen core, then it is necessary to subtract this error length, then the error length at this time is a positive number, thereby ensuring the accuracy of the scale line, and if the set adjustment state is the core-in state, the pen core needs to be retracted in the pen changing part for a certain stroke, then the error length is equal to the retracted stroke, then it is necessary to add this error length at this time, then the error length at this time is a negative number;

[0732] It is also possible to directly mark the length scale of the ordinary actual distance, allowing users to calculate and adjust it by themselves; at the same time, it can improve the application scenarios of external adjustment tools. However, for targeted use, only more targeted scales such as G2 and G5 can satisfy consumers to accurately adjust the internal length.

[0733] 26. When the controlled switching wall is not used, the switching long wall or the core-collecting auxiliary wall should be extended upward or downward for a certain distance to ensure that it can cover the area directly above or below the limiting boss; thereby ensuring that the displacement member or the replacement part of the displacement member can successfully bypass the influence range of the limiting boss when passing through, thereby ensuring that the first pulling plan can be implemented normally; and the limiting return slope can reduce the coverage requirements for the switching long wall or the core-collecting auxiliary wall, because the limiting return slope can provide a certain slope guidance effect.

[0734] 27. In some embodiments, the positioning member 7 and the trigger cover 63 can be produced in an integrated manner according to actual conditions, thereby saving mold costs and installation procedures; similarly, the integrated production of other components can also be normally inferred and improved by those skilled in the art.

[0735] 28. It can be concluded from the embodiments of the present invention that the structure of the present invention is very flexible, and there is a huge space for change and design. At the same time, the technical effects that can be achieved are also huge, and the cost can be controlled, and it has the commercial value of mass production. Therefore, the present invention also protects the design ideas, operating ideas and operating methods of the present invention. Any modifications to the present invention that are similar to the deformation design and alternative design that are equivalent to the present invention should fall within the protection scope of the present invention.

[0736] 29. When the core is pulled up and retracted, because the maximum limit of downward movement is adopted, in most cases, if a positioning part is used, the positioning part is installed into the outer rod from top to bottom together with the control part; then it is restricted by the internal structure of the outer rod, for example: adding a limit ring 12 to limit the maximum limit of downward movement; and the installation method of the connecting part 11 itself is adopted, because the connecting part breaks the outer rod, some parts are installed into the outer rod from top to bottom: such as some parts related to the trigger assembly, and other parts are installed into the outer rod from bottom to top, such as adjusting parts, positioning parts and auxiliary reset parts.

[0737] 30. In order to enable the rotating part to offset the negative interference caused by gravity, it is best to adjust the structure of the part itself, such as adding a clamping structure to the adjusting part to clamp the rotating part from the front and back of the rotating part. Then the rotating part does not need to rely on the clamping between the adjusting part and the positioning part. The stability will be higher by clamping it alone through the adjusting part. In this way, the accuracy requirement for the displacement part 821 will be greatly reduced. There are many ways to better enable the rotating part to offset gravity, such as: 1. Add rough texture to the annular surface of the rotating boss 412, thereby increasing the friction between the rotating part 82 and the rotating boss 412, thereby offsetting the negative impact of gravity; 2. Add elastic components to limit the rotating part; 3. Provide magnetic attraction to the rotating part through magnets to counteract gravity interference; 4. Increase the friction of the positioning groove; 5. Use a multi-level structure on the positioning groove to prevent the rotating part from moving back; 6. Add stepped restrictions on the displacement part 41 to constrain the rotating part.

[0738] 31. Because the structure of the present invention can be turned upside down, it can be installed upright and the core can be pulled out by pulling, or it can be installed in reverse and the core can be collected by pressing the tail. Therefore, the upward or downward movement in the present invention is actually changed according to the main orientation of the specific scheme. It is not necessary for the adjustment part to move up to remove the core. When the tail is pressed to collect the core, the adjustment part takes the opposite downward movement to remove the core.

[0739] 32. The switching long wall 71B itself has two main functions, the first is to help with core ejection, and the second is to help with core collection; these two seemingly opposite functions can exist alone or at the same time, depending on the actual needs. Because, in order to be more stable and improve the fault tolerance rate, the function of the switching long wall 71B in helping with core collection in Example 4 is replaced by the core collection auxiliary wall 717, and the switching long wall 71B is only responsible for helping with core ejection; and because Example 5 does not need to help with core ejection, it only needs to provide the function of helping with core collection.

[0740] 33. In order to further improve the stability of the control member 2, the control groove specifically accommodating the control rod 21 can be extended downward or upward for a certain distance to form a control deep groove 7151, and the head of the control rod 21 is also extended. Then, even in the triggered state, when the control member 21 moves up or down to the maximum distance, the head of the control rod 21 remains partially located in the control deep groove 7151, so that when the displacement member 41 falls back, no cavity is formed in the positioning groove, thereby ensuring the stability of the overall operation.

[0741] 34. The above-mentioned 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, but the structure itself is of great significance and cannot be regarded as just a simple extension part of the control rod 21. Because the function of the entire invention has also undergone a significant upgrade due to the emergence of the limiting boss 211, and a plurality of different core-collecting methods have been expanded. It is a key technical point for realizing the core-collecting by pulling and pressing, and the falling auxiliary slope 213 further supplements and expands the limiting boss 211, making it more functional. Making the limiting boss 211 independent as a separate accessory or replacing it with a similar structure are both equivalent replacements. Equivalent replacements for other similar parts of the present invention should also be regarded as within the scope of protection of the present invention.

[0742] 35. The definition of "bypassing" mentioned above is to take the core outlet B as the starting point and circle around the limiting boss 211, such as: circle around the limiting boss 211 half a circle upward or downward, and circle to the other side of the limiting boss 211 corresponding to the core outlet B, thereby leaving the original core outlet B, thereby achieving core collection.

[0743] 36. The definition of "going over" mentioned above is to move over the main body of the limiting boss 211 starting from the core outlet B; because the limiting boss 211 itself serves to temporarily limit the limiting boss 211, the adjusting member can climb over the limiting boss 211 by auxiliary means such as a fall-back auxiliary slope; but for the sake of safety, it is better not to climb over the limiting boss 211 from the core outlet B, and it is better to climb over the upper or lower part of the core outlet limiting boss. Whether it is through the top or the bottom depends on the direction of the positioning groove of the adopted scheme, and the direction of the positioning groove is determined by whether the lifting scheme or the pressing scheme is adopted; such as: first go around from the core outlet B to the top or the bottom of the limiting boss 211, and then rebound up or down through the force of the reset member, and when it contacts the top or the bottom of the limiting boss 211, the displacement member 41 passes over the limiting boss 211 through the return auxiliary slope, thereby reaching the other side opposite to the return auxiliary slope, thereby realizing core collection.

[0744] 37. The external adjustment tool is also provided with scale lines related to the product, which 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 actual length of the tool body of different specifications; 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; and the distance between the exposed and retracted tool body can also be parameterized, and after setting, it is also a constant value;

[0745] When the adjusting member and the outer rod are in the retracted state, the actual length of the tool body + the distance of the tool body 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 the adjusting member after removing the pen-changing part and the bottom surface of the adjustable base;

[0746] When the adjusting member 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 the adjusting member after removing the pen-changing part and the bottom surface of the adjustable base;

[0747] When the external adjustment tool extends into the external rod or the adjustment rod and contacts the adjustable base, the distance between the head of the external adjustment tool and the bottom surface of the external rod or the adjustment member after the pen-changing portion is removed is equal to the distance between the bottom surface of the external rod or the adjustment member after the pen-changing portion is removed and the bottom surface of the adjustable base;

[0748] According to different states, different tool bodies can clearly correspond to the distance between the bottom surface of an outer rod or adjustment member after removing the pen-changing part and the bottom surface of the adjustable base. 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 member after removing the pen-changing part and the bottom surface of the adjustable base calculated by different tool bodies under different states;

[0749] In order to facilitate labeling and prevent consumer confusion, it is best to mark the scale lines of the length required for different tool bodies when the core is in the core-out state or the core-in state;

[0750] For example, the end of the external adjustment tool can be written with "please adjust in the core-out state" or "please adjust in the core-in state"; then the scale lines correspond to the scale lines of the different tool body product specifications, and the product specification abbreviation or number is directly written next to the scale lines. If the number is defined by the merchant, the corresponding instruction manual needs to be attached;

[0751] In this way, when consumers adjust the distance, they do not need to remember so many related parameters to calculate what distance should be adjusted, which greatly improves the practicality and convenience of adjustment.

[0752] The above is an explanation of the setting of the external adjustment tool based on the use of the pen-changing part. It can also be adjusted from the other end of the overall structure. The calculation method and principle are similar and the details are the same as above.

[0753] 38. The design structure of the present invention is ingenious and perfect, the design concept and ideas are clear, the functions are rich, and it has huge market potential. The above-mentioned tool body is not only suitable for various types of writing tools, but also for other products that require this function, such as: lipstick, hand knives, keys, screwdrivers, eyebrow pencils, ear spoons, medicine boxes, erasers, switches or headphones.

[0754] 39. The core function of the reset member is to provide a continuous unidirectional force to the outer rod and the adjusting member, and this force is usually achieved through a compressive elastic element, or through the repulsive force of magnetic attraction; because the fundamental purpose is to provide a continuous unidirectional force, a continuous unidirectional force can also be provided by using a tensile elastic element or a magnetic attraction force at the opposite position. Therefore, the reset member has great flexibility in changing, but no matter how it is changed, as long as the function is to provide a continuous force, it should be equivalent to the function of the reset member of the present invention.

[0755] 40. When the switching slope is not used as mentioned above and a cover body is added to the outer rod, it can be chosen whether to be changed to the cover body according to the situation. If it is changed to the cover body, it will be beneficial to production. Therefore, considering the actual production needs, other parts of the structure can also choose to add new accessories according to the situation, and some structures can be changed to the new accessories or other accessories.

[0756] 41. The explanation for the relative stability of the two position states achieved by the above-mentioned adjusting member through the positioning groove, the reset member and the control member is as follows: the reset member is transmitted through the tool body, thereby indirectly giving the adjusting member a continuous force, and there is a dynamic and static displacement fixed relationship between the positioning groove and the adjusting member. The adjusting member determines the state of core output or core collection by moving its position in the positioning groove, and the switching between the two position relationships requires the adjustment member to move and switch in the positioning groove; and the reason why it is said to be a dynamic or static displacement fixed relationship is that when the adjusting member is located at the core collection position of the positioning groove, it is static, and at this time it is just the positioning groove. And the coordination relationship between the positioning part and the adjusting part, and when the adjusting part is at the core outlet of the positioning groove, it belongs to a kind of dynamic position relationship, because the core outlet is composed of the control part and the core outlet boss in the positioning groove. Although the core outlet boss is relatively fixed, the control part is dynamically movable, and the existence of the core outlet can be dynamically determined by the control part; when the control part moves up or down, the core outlet will lose its original function and the adjusting part cannot be effectively fixed. At this time, the adjusting part will return to the core receiving part; and when the control part returns to its position, at this time, when the adjusting part moves to the core outlet again, it can ensure that it stays effectively at the core outlet.

[0757] 42. The main function of the positioning part 72 is to replace the positioning member 7 to contact the tool body 5, so that the tail end of the tool body 5 can be limited, and the core collection and core extraction can be accurately controlled only by the displacement of the adjustment member; therefore, the positioning part 72 can be integrally formed with the outer rod, or it can be separated into an independent accessory and installed in the outer rod in the form of an accessory;

[0758] 43. In order to facilitate production, the required rotating boss can be installed on the adjusting part in the form of a separate accessory.

[0759] 44. In certain circumstances, the height of the core-outlet boss 713 is lower than the depth of the positioning groove. This situation is generally used when an auxiliary structure such as a switching long wall is not used and the core-outlet position B is entered by crossing the core-outlet boss. In order to better cross the core-outlet boss and prevent the displacement member 41 from being separated from the positioning groove due to misoperation, the height of the core-outlet boss can be appropriately reduced to ensure an increase in the effect.

[0760] 45. The structural variation possibilities of the present invention are very large. Therefore, the matching relationship between the various components, the position relationship, the actual operation position, the position of the direct structural conflict, whether the pen-changing part is placed on the outer rod or the inner rod, and the different application scenarios of the cover body, the structural variation of the outer rod are all determined according to the actual situation. The following are some of the changes that need to be noted:

[0761] 1. The tail abutment part of the tool body can be the bottom of the positioning member, the adjusting abutment part of the adjusting member, or the positioning part of the outer rod; and this corresponds to when the tail of the tool body abuts the bottom of the positioning member or the positioning part of the outer rod, the movement of the adjusting member will directly determine the exposure and core collection of the tool body, and the reset member and the front end of the tool body are basically located in the adjusting member, and when the tail of the tool body abuts the adjusting abutment part of the adjusting member, the movement of the adjusting member will indirectly determine the exposure and core collection of the tool body, and at this time, the reset member and the front end of the tool body are basically located in the outer rod;

[0762] Second, the auxiliary reset member can be located between the control member and the cover body, or between the positioning member and the control member, between the control member and the outer rod, between the control member and the trigger cover body, or between the control member and the adjusting member; when located at different positions, many corresponding structures will also change accordingly;

[0763] 3. The operation 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 divided into many situations; some compatible relationships listed in the present invention are only preliminary classifications, and can be increased or decreased according to the changes in the actual structure;

[0764] Fourth, the position of the positioning groove is variable, and it can be placed on the positioning piece or on the outer rod, and the visual effect and actual production situation are also different;

[0765] 5. The shape and structure of the notch of the positioning groove are varied. The structure of the positioning groove has many variations according to the different operating functions that need to be realized. The embodiments of the present invention only list some application scenarios, and other application scenarios can be supplemented and adjusted according to actual conditions.

[0766] 6. The shape and structure of the control parts are also varied. The changes in the positioning grooves, the different operating methods required, the influence and interference of the installation direction and other factors determine the changes in the control parts. To a certain extent, the control parts can also improve the stability of the adjustment parts by adding some stable structures;

[0767] 7. The push rod can be changed. The push rod can be integrated production, fixed installation or rotating installation according to factors such as process, production, and the operating effect to be achieved. The rotating installation can be fixed at one end and rotated on one side or fixed in the middle and rotated at both ends;

[0768] 8. The trigger assembly is changeable. The trigger assembly can be selected to move the limiter or the cover body according to the needs, or it can be moved by the trigger rod. The triggering form of the present invention is very changeable, and the present invention only lists a part of it;

[0769] 9. The outer rod is changeable. The tail can be replaced by a cover body or a rotating fixture, or a connector, a push rod, a pen clip, a pen changing part and / or a positioning part can be added;

[0770] 10. The adjustment members are changeable and have a wide range of adjustment. The functions and effects achieved are also different. The upper end of the outer rod may be partially exposed, the lower end of the outer rod may be partially exposed, the side portion of the outer rod may be partially exposed, or the outer rod may be completely hidden in the outer rod. The shape and structure of the adjustment members also change accordingly. For example, the shapes of many positioning members in the embodiments do not look like the same member at all. Because the range of adjustment members is too wide, the functions and effects achieved are also very powerful. According to the variability of the positioning members, a large number of core-out and core-back operations can be achieved, and a variety of different core-out operations or a variety of different core-back operations can coexist. Although the positioning members are so changeable, they can all be summarized and expressed as the same member. The reason for their variability is the adaptive adjustment based on actual conditions and needs.

[0771] 46. ​​The rotating part is a swivel hook made of metal, or a special-shaped structure made of metal, or a special-shaped structure made of plastic. Its main function is to provide a matching component for left and right steering.

[0772] 47. The rotating boss 412 may also be provided with a rotating fastener 4121; the rotating fastener may be installed in the form of a separate accessory, and may be installed in the form of a fastener, and may be tighter or looser. If the rotating member is properly tighter while ensuring that the rotating member can rotate left and right normally, the interference of gravity may be overcome directly. The contact surface between the rotating fastener and the rotating member may also be properly designed and modified to improve the actual use effect; the rotating stabilizing boss 45 may also, to a certain extent, use the principle of the rotating fastener to apply pressure to the rotating member, thereby overcoming the interference of gravity; the rotating stabilizing boss 45 and the rotating fastener 4121 may exist at the same time. When the two exist at the same time, the rotating stabilizing boss 45 needs to ensure that the rotating fastener 4121 can be installed normally, such as bypassing the rotating fastener 4121 or providing a through hole to facilitate the installation of the rotating fastener 4121.

[0773] 48. The adjustment part and the pen changing part can be matched by magnetic attraction, snap fit or threaded fit. The displacement direction and the contact position of the control rod 21 by magnetic attraction and rotatable snap fit will also determine and affect the force required for triggering. For better triggering, although the control rod 21 will contact the displacement limiting part 41, the main load-bearing point should be designed on the core-out boss 713 in the positioning part groove. The core-out boss 713 mainly bears the action force of the reset part 3 to ensure that the force required to pull out the control rod 21 to release the limit and trigger the core collection is only a contact force.

[0774] 49. When the snap fit is performed, the adjustment member can be rotated relative to the pen-changing portion while ensuring the fit, thereby facilitating the fit between the adjustment member and the positioning groove.

[0775] 50. The function of the above-mentioned rotating fastener 4121 can also be directly integrated into the rotating boss. The rotating boss is provided with a pressure flap 41212. After the rotating member is directly inserted into the rotating boss, the pressure flap can achieve the clamping effect without a pressure column. However, when the rotating fastener is used as a separate accessory, the use of a pressure column can also save more materials, and the resilience will be better. Of course, when the rotating fastener is integrated into the rotating boss, it is also possible to use a pressure column at the same time.

[0776] 51. The displacement direction and the degree of the resistance force of the control member 21 will greatly affect the triggering force. The displacement direction is mainly because it will cause the principle and structure of the resistance to change, thus affecting the degree of the resistance force. The degree of the resistance force is proportional to the triggering force. The smaller the degree of the resistance force, the smaller the triggering force. Therefore, reducing the degree of the resistance force can also reduce the triggering force. The selection of the displacement direction is very important because the displacement direction will also determine the stability during writing. The displacement direction will have different effects according to the actual internal structure design. If the current internal structure is used as the standard, the resistance force will be relatively reduced when the control member 21 moves up and down or forward and backward. However, if the contact resistance is moved left and right, it will be difficult to implement and control due to the structural principle. Secondly, it will destroy the stability of the use state and / or increase the triggering force. Because when moving left and right, the use state must be considered first. In order to improve the stability of the state, and to increase the stability of the use state, it is necessary to increase the strength of the stable control member, and increasing the stabilizing strength of the control member will lead to an increase in the triggering force and a decrease in the triggering sensitivity; in this case, the stability of use and the triggering force are inversely proportional, so it will be very difficult to balance these two points accordingly, and there will be a situation where you cannot have your cake and eat it too much, and if you go with the flow and move up and down or back and forth, the stability of the use state and the triggering force will be separated, and they will not interfere with each other excessively and be directly related; it is possible to reduce the triggering force as much as possible while ensuring the stability of the use state, and achieve the effect of having both fish and bear's paw; because, at this time, whether the control rod moves up and down or back and forth, it will not affect the left and right movement of the displacement member 41, and the two will not be directly related; therefore, the optimal displacement orientation of the control member 21 depends on the movement trajectory of the displacement member 41, especially the movement trajectory of the core-out switching to the core-back process.

[0777] 52. The deformation slot 713K can make the structure have a certain deformation resilience. Therefore, it can be added to the core-out boss 713, the positioning member 7, the displacement member 41, the adjustment member, the control member 2, the outer rod 1, the rotating member 82 and / or the rotating abutment boss 413; provide better deformation space and deformation force for the required structure, and at the same time, reverse the structure that originally needs deformation force so that it does not need deformation force, and add deformation slots 713K to the corresponding structure that needs to cooperate with it, so that it has deformation force. This method can be better utilized according to different usage structures and internal structure space conditions. As shown in Example 16, the displacement member 41 is replaced by the rotating member 82. If the rotating member 82 is used for deformation, it is necessary to provide the rotating member 82 with deformation space. This is not difficult. The main thing is that if the rotating member 82 has deformation ability, it will cause the rotating member 82 to be easily separated from the positioning slot 71, which will cause the instability of the overall structure and increase a lot of uncertainty. factors; and if it is ensured that the rotating member 82 does not have too high a deformation capacity, the core-out boss 713 is used for deformation, so that the internal space can be better utilized, and at the same time, there is no need to worry about the rotating member 82 being out of the positioning groove; and for the installation of components, the deformation notch 713K can also provide convenience and stability. As shown in Example 15, the rotating snap-in portion 41211 on the rotating fastener 4121 is better fitted into the rotating boss 412 by adding a deformation notch 713K; while providing a larger production error, it ensures practical stability after installation; it can also provide a better resistance effect for the resistance of the components. For example, in Example 8, the clamping portion 4131 needs to resist the rotating member 82. At this time, if the clamping portion 4131 has the deformation capacity, it can better resist the rotating member 82. Therefore, by adding a deformation notch 713K near the clamping portion 4131 on the rotating fastener 4121, the resistance effect of the clamping portion 4131 can be greatly improved.

[0778] 53. It can also be seen from Example 8 that the matching methods of the rotating member 82 and the rotating boss 412 are also very diverse, and are not limited to a hole provided on the rotating member 82 to be sleeved on the rotating boss 412. It is also possible that a rotating boss 412 is provided on the rotating member 82, and a rotating through hole 41F is provided on the displacement member 41, and the rotating boss 412 on the rotating member 82 is installed in the rotating through hole 41F for use.
