Description

[Name of invention established by ISA according to Rule 37.2] 　A repetitive reset pen

Technical field

The invention relates to a pen, in particular to a repetitive position pen.

Background technique

At present, there are many kinds of pens on the market, and their appearances are different. People mainly use pens with caps and pressing pens. The main reason is that their structure is stable and easy to use. Although other new pens have been designed, they are more convenient. Performance; comfort and stability are still not as good as these two main pen types; although the current operation method of pressing pen is very simple, and the operation is stable; however, even if we choose the current operation method, the fastest pressing is As far as the pen is concerned, its operation method still requires two or three actions, as follows:

If the holding posture is writing, then: 1. You need to rotate the pen so that your thumb is facing the button; 2. Then press down; 3. Rotate the pen again to change back to the normal writing posture; if you hold it up In the pressed state, then: 1. Press directly; 2. Rotate the pen to return to the normal writing posture; first of all, the above methods are inseparable from the rotating pen, and the time required to rotate the pen is about 1 to 2 seconds. Normal operation speed requires at least 2 seconds or more; secondly, picking up is directly pressing, which requires high pen placement; in the process of picking up, the fingers need to adjust the posture several times. At the same time, the current pen does not have a self-locking function. Long-distance and long-term carrying is easy to contaminate the backpack with ink; and it is inconvenient to replace the refill, requiring a lot of rotations before replacement.

Then the assembly of the rotating inner core and the pusher is completed; at this time, the assembled rotating pusher is projected upward with the closed ring of the inner sleeve, and inserted into the inner sleeve from bottom to top;

When not in use, the switching boss is located in the movable straight groove; by squeezing the propelling piece, the propelling guide slope will continue to interfere with the use of the guide slope. At this time, the use of the guide slope and the propulsion guide slope are in a semi-contact state, and Forcing the rotating inner core to move up continuously, when the switching boss is out of the matching range of the movable straight groove, the use of the guide slope will fully cooperate with the advancing guide slope, and the rotating inner core will be forced to rotate to a certain extent, which makes the use of the guide slope again It has half contact with the conversion slope. When the pusher is released, the force of the return spring will cause the rotating inner core to reset, but at this time the use of the guide slope has already had half contact with the conversion slope, so it will It directly causes the rotating inner core to spin further, so that the switching boss is stuck on the top of the supporting boss. At this time, it is in the short-fitting state, that is, the in-use state, and the tip of the pen core remains exposed to the front rod.

At this time, if the propelling piece is pressed again, the advancing guide slope at this moment will continue to interfere with the de-locking guide slope. At this time, the propelling guide slope and the de-locking guide slope are in a semi-contact state, and the rotating inner core is forced to continue. Move up, when the switching boss is out of the matching range of the movable straight groove, the de-engagement guide slope is fully matched with the propulsion guide slope, and the rotating inner core is forced to rotate to a certain extent, so that the use of the guide slope is separated from the conversion slope. When the pusher is loosened, the force of the return spring will cause the pusher to reset, but at this time the pull-off guide slope is already in contact with the transition slope. Half contact occurs, so it will directly cause the rotating inner core to spin further, so that the switching boss breaks away from the conflict with the support boss, and slides into the movable straight groove again, then the long fit state is at this time, that is, it is not. In use, the tip of the pen core remains retracted in the front rod.

As a further preference: a push spring is also provided between the inner sleeve and the adjusting inner rotating part; the push spring is used to separate the rear penholder assembly from the positive pressure elastic return pen; because when the switching boss is stuck on the top of the supporting boss At this time, the propelling member is in any up and down movable state in the movable straight groove, and the propelling member is the connecting link between the rear penholder assembly and the positive pressure elastic reset pen. When the propelling member is in any up and down movable state, the rear penholder The component and the positive pressure elastic return pen will shake up and down randomly. The addition of a push spring can prevent the rear penholder assembly and the positive pressure elastic return pen from swaying up and down, making it more stable in use and meeting people's needs.

As a further preference: a tail cover and a hook can be added to the tail of the rear penholder assembly.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Example 1:

As shown in Figures 1-9, a barrel repositioning pen includes a front rod 1, a rear penholder assembly, a pen core 4, a return spring 41, an adjusting inner rotation member 47 and a reset movement. The return spring 41 and the pen core 4 are both located in the rod body of the front rod 1, and the return spring 41 is specifically clamped between the pen core 4 and the front rod 1. The return spring 41, the refill 4 and the reset movement are sequentially installed in the front rod 1, and the tail end of the refill 4 conflicts with the reset movement. The above-mentioned reset movement is engaged with the front rod 1 so that it is not easy to get out of the front rod 1, thereby forming a positive pressure elastic force reset pen. The positive pressure elastic reset pen has two forms, namely the in-use state and the non-in-use state. The specific differences, the process of form transformation and the principle of form change are as follows:

The specific difference is that: in the state of use, the tip of the pen core 4 remains exposed at this time. In the unused state, the tip of the pen core 4 is hidden in the front rod 1 at this time. The principle of morphological change is mainly determined by the reset movement, and the principle of the reset movement is as follows: the reset movement is composed of at least a fixed shell and an internal displacement device, and there are at least two morphological changes with a stable positional relationship between the internal displacement device and the fixed shell. . The specific position and form change into a short fit and a long fit. The difference between the distance between the bottom end of the fixed case of the reset movement and the top of the internal displacement device in the above-mentioned short fit and the distance between the bottom end of the fixed case of the reset movement and the top of the internal displacement device in the long fit The value is equal to the difference between the exposure of the refill 4 and the retracted front rod 1.

Transformation process: 1. When in use, the reset movement is in a short-fitting state. At this time, the internal displacement device is closer to the core hole of the front rod 1. The specific distance is the total length of the refill 4 minus the use state The distance of the core hole exposed outside the refill 4. 2. When not in use, the reset movement is in a long fit state. At this time, the internal displacement device is closer to the core hole of the front rod 1. The specific distance is the total length of the refill 4 plus the refill in the unused state. 4 When the pen tip is hidden in the front rod 1, the distance from the core hole.

The other end of the above-mentioned reset movement is screwed into the adjusting inner rotating member 47. The front rod 1 is partially sleeved in the rear penholder assembly. The inner adjusting member 47 is screwed to the inner end of the rear penholder assembly. Then, the rear penholder assembly is assembled by adjusting the inner rotation member 47 and the positive pressure elastic force reset pen, so that it can be operated in reverse. The rear penholder assembly can be clamped by the tiger's mouth part of the hand, and then the index finger and middle finger clamp the front end of the front rod 1 to move it closer to the tiger's mouth, so that the length of the reset movement can be switched, thereby switching its correctness. Squeeze the elastic force to reset the matching form of the pen.

In order to enable the writing instrument to meet the requirements for carrying out, and to face the complex and changeable environment when carrying out, it is more stable; the front rod 1 is provided with a self-locking groove 11. The self-locking groove 11 is composed of an installation groove area 111, a self-locking groove area 113 and a straight sliding groove 114. The above-mentioned rear penholder assembly is also provided with a self-locking point 31. The above-mentioned self-locking clamping point 31 quickly enters the self-locking groove 11 through the installation groove area 111. The end of the straight sliding groove 114 close to the self-locking groove area 113 is the end, and the other end is the front end. When in use, the self-locking point 31 is located close to the front end of the straight chute 114, but there is still a sufficient distance from the front end to reset the movement switching state, so as to reset the movement state switching. When not in use, the self-locking point 31 is located close to the end of the straight chute 114, but the distance from the end is still 0.1-2 mm. Prevent the self-locking card point 31 from entering the self-locking slot area 113 by mistake.

In order to make its appearance more scientific and technological, and correct the grip posture, so that people’s grip posture is more scientific; the above-mentioned rear penholder assembly is composed of a rotating middle rod 2 and a rear pen holder 3, and the above-mentioned rear pen holder 3 and the rotating middle rod 2 are integrated with each other , Make it inseparable, but can rotate freely. The above-mentioned self-locking point 31 is specifically located on the rear pen barrel 3 of the rear pen barrel assembly. The front rod 1 is provided with a plurality of bamboo joint outer rods 12. A sliding gap is left between the above-mentioned bamboo outer rods 12. The front end of the rotating middle rod 2 is extended with the inner bamboo rods 21 in the same number as the outer bamboo rods 12, and the inner bamboo rods 21 slide in the sliding gap to make them contact with the outer rods 12 in staggered arrangement. . And it is ensured that the rear pen holder 3 can still rotate freely relative to the front rod 1, so that the self-locking point 31 can still be rotated to enter and exit the self-locking groove area 113 on the front rod 1.

In order to quickly replace the pen core and ensure sufficient stability, the structure is not easy to separate, and it can also be better shock-absorbing; an assembly ring 48 and a fixing ring 49 are also provided between the reset movement and the front rod 1. The above-mentioned assembling ring 48 is fixed to the rear part of the front rod 1. The fixing ring 49 is fixed to one end of the reset movement. One of the above-mentioned assembling ring 48 and fixing ring 49 must be made of a permanent magnet or a substance with magnetism, and if the other is not made of a permanent magnet or a substance with magnetism, it is made of a substance that can be magnetically attracted. And after the assembly ring 48 and the fixed ring 49 are adsorbed and assembled, the assembly ring 48 and the fixed ring 49 are mutually adsorbed, and the upper and lower separation requires external force, so that the entire reset movement rotates more smoothly with respect to the front rod.

In order to improve its better comfort and protect the hands; the front rod 1 is also provided with the same number of latching bamboo joints 13 as the number of bamboo joint outer rods 12. The above-mentioned card position bamboo joint 13 and the bamboo joint outer rod 12 are kept on the same horizontal line. A writing sleeve 4c is also provided between the above-mentioned card position bamboo joint 13 and the bamboo joint outer rod 12.

The upper end of the inner bamboo rod 2 of the above-mentioned rotating middle rod 2 is also provided with a tiger-mouth sleeve 44. A clamping sleeve 43 is also provided at the front end of the locking bamboo joint 13 of the front rod 1.

The above-mentioned reset movement includes a sliding reset cylinder 51 and a reset telescopic rod 52. The sliding reset cylinder 51 is equal to the fixed shell. The above-mentioned reset telescopic rod 52 is equal to the above-mentioned internal displacement device.

Both sides of the sliding reset cylinder 51 are provided with a used slot 512 and an unused slot 511, and a matching inner cylinder 514 is also provided in the cylinder. A reset triangular boss 513 is also provided between the used slot 512 and the unused slot 511 on the sliding reset cylinder 51. The unused slot 511 is also provided with a switching slope 5111 near the end of the used slot 512. The above-mentioned use slot 512 is also provided with a switching matching slope 5121 near the end of the matching inner cylinder 514.

The rear end of the reset telescopic rod 52 is provided with an external thread, and the external thread is matched with the internal thread of the adjusting inner rotating member 47, and two matching rods 521 and a plurality of pen core support rods 522 are respectively extended at the front end. The end of the mating rod 521 is also provided with an engaging hook base 5211. One of the two engaging hook bases 5211 is provided with a mating groove 5212, and the other is provided with a mating clamping point 5213.

When the above-mentioned engagement hook base 5211 is located in the unused slot 511, it is in an unused state. When the rear penholder assembly and the front rod 1 are squeezed by an external force to engage the hook base 5211, it enters the use slot 512 by switching the use slope 5111 When, it is in use. When the rear penholder assembly and the front rod 1 are squeezed by an external force. When the engaging hook base 5211 enters the mating groove 5212, the above-mentioned mating groove 5212 and the mating clamping point 5213 enter the mating inner cylinder 514 at the same time, and they will engage with each other. When the external force disappears, the engaging hook platform 5211 will be engaged. When the slot 512 is used, it will not engage with it. After using the slot 512 and then passing through the reset triangular boss 513, the engagement of the above-mentioned fitting groove 5212 and the mating engagement point 5213 is separated by the reset triangular boss 513. At this time, the separated engagement hook platform 5211 Then, you can enter the unused slot 511 to restore it to the unused state.

Both sides of the reset triangular boss 513 are provided with slopes 5131 that gradually decrease from bottom to top. It can better help the engagement of the mating groove 5212 and the mating clamping point 5213 to be separated by the reset triangular boss 513. The specific separation positions of the above-mentioned mating groove 5212 and the mating clamping point 5213 are preferably located between the used slot 512 and the unused slot 511. There is a triangular boss sliding gap between the refill support rods 522 to prevent the resetting triangular boss 513 from affecting the resetting telescopic rod 52 to slide in the slideway resetting cylinder 51. The length of the pen core support rod 522 is longer than the mating rod 521, so that it can pass through the switching mating slope 5121 and conflict with the end of the pen core 4. Provide support for refill 4. One of the two engaging hook bases 5211 is provided with a first magnetic fitting 4a, and the other is provided with a second magnetic fitting 4b. One of the above-mentioned first magnetic fitting 4a and second magnetic fitting 4b must be made of a permanent magnet or a material with magnetism. If the other is not made of a permanent magnet or a material with magnetism, it is made of a material that can be magnetically attracted. to make. When the engaging hook platform 5211 enters the mating inner cylinder 514, the first magnetic fitting 4a and the second magnetic fitting 4b will have a magnetic fit, and will not engage with the first magnetic fitting 4a and the second magnetic fitting 4b when they fall through the use slot 512. After the slot 512 is used, it will be separated when it passes through the reset triangular boss 513 and enters the unused slot 511.

Example 2:

A barrel repositioning pen as shown in Figures 1 to 4 and 10 to 15 includes a front rod 1, a rear pen rod assembly, a pen core 4, a return spring 41, an adjusting inner rotation member 47 and a reset movement. The return spring 41 and the pen core 4 are both located in the rod body of the front rod 1, and the return spring 41 is specifically clamped between the pen core 4 and the front rod 1. The return spring 41, the refill 4 and the reset movement are sequentially installed in the front rod 1, and the tail end of the refill 4 conflicts with the reset movement. The above-mentioned reset movement is engaged with the front rod 1 so that it is not easy to get out of the front rod 1, thereby forming a positive pressure elastic force reset pen. The above-mentioned positive pressure elastic force reset pen has two forms, namely the in-use state and the non-in-use state. The specific differences, the process of form transformation and the principle of form change are as follows:

Transformation process: When in use, the reset movement is in a short-fitting state. At this time, the internal displacement device is closer to the core hole of the front rod 1. The specific distance is the total length of the refill 4 minus the refill in the use state. 4 The distance of the exposed core hole. When not in use, the reset movement is in a long fit state. At this time, the internal displacement device is closer to the core hole of the front rod 1. The specific distance is the total length of the refill 4 plus the tip of the refill 4 in the unused state. When hidden in the front rod 1, the distance from the core hole. The other end of the above-mentioned reset movement is screwed into the adjusting inner rotating member 47. The front rod 1 is partially sleeved in the rear penholder assembly. The inner adjusting member 47 is screwed to the inner end of the rear penholder assembly. Then, the rear penholder assembly is assembled by adjusting the inner rotation member 47 and the positive pressure elastic force reset pen, so that it can be operated in reverse. The rear penholder assembly can be clamped by the tiger's mouth part of the hand, and then the index finger and middle finger clamp the front end of the front rod 1 to move it closer to the tiger's mouth, so that the length of the reset movement can be switched, thereby switching its correctness. Squeeze the elastic force to reset the matching form of the pen.

The upper end of the inner bamboo rod 2 of the above-mentioned rotating middle rod 2 is also provided with a tiger-mouth sleeve 44.

A clamping sleeve 43 is also provided at the front end of the locking bamboo joint 13 of the front rod 1.

The above-mentioned reset movement includes an outer collar 61, an inner rotating member 62, a locking member 63 and a central shaft body 64. The outer collar 61 is equal to the fixed shell. The inner rotation member 62, the locking member 63, and the central shaft body 64 are combined to form an inner rotation shaft member, and the inner rotation shaft member is equal to the above internal displacement device.

The end of the central shaft body 64 is provided with an external thread, and the external thread is matched with the internal thread of the adjusting inner rotating member 47. The front end is provided with a pen core abutment table 643 with an outer diameter equal to the outer diameter of the locking member 63, and a fitting is provided in the middle. The ring platform 641, the above-mentioned fitting ring platform 641 is divided into multiple parts by a plurality of cutting gaps 642. After being cut, the fitting ring platform 641 has a certain deformability and can pass through the inner rotation member 62. The above-mentioned fitting ring platform 641 is provided with an installation auxiliary slope 6411 at its upper end. In order to pass through the inner rotation member 62. Both the outer collar 61 and the inner rotating member 62 are hollow sleeves. One to more inner clamping stations 611 are provided in the inner cylinder of the outer collar 61. The surface of the inner rotation member 62 is provided with matching grooves 621 with the same number as the inner clamping platform 611, and a use boss 622 is also provided in the matching groove 621. The front end of the mating groove 621 is provided with a locking cut-in groove 6211. The above-mentioned locking member 63 is provided with extended locking bosses 63 having the same number as the locking cut-in groove 6211. After the above-mentioned locking member 63 enters the mating groove 621 through the locking cut-in groove 6211 through the inner clamping platform 611, the locking projection 63 closes the locking cut-in groove 6211. Preventing the inner clamping platform 611 from disengaging from the mating groove 621 also prevents the inner rotating member 62 from disengaging from the outer collar 61. When the locking member 63 is clamped into the inner rotating member 62, the end of the locking member 63 passes through the central shaft 64 and passes through the inner rotating member 62 combined with the locking member 63 from the bottom to the top, and when it fits with the ring platform 641 When passing through the inner rotation member 62, it will return to its original state and form a engagement with the inner rotation member 62. At this time, the entire reset movement is assembled.

The closed ring groove formed between the mating groove 621, the using boss 622, and the locking member 63 is divided into an unused resting area 6212, a sliding groove 6215, a state switching groove 6213, and a recovery curved groove 6214 through different functions. The above-mentioned use boss 622 is provided with a switching landslide 6221 and an anti-falling boss 6222. A stationary groove 6223 is formed between the switching landslide 6221 and the anti-falling boss 6222. The above-mentioned inner rotation member 62 is also provided with a switching slope 623 and a switching slope 624 that are not used. A stop limit platform 625 is also provided between the switching slope 623 and the switching slope 624 described above.

When the above-mentioned inner card table 611 is located in the unused resting area 6212, it is in an unused state. When the rear penholder assembly and the front rod 1 are squeezed by external force, the inner card table 611 enters by using the chute 6215 and using the switching slope 623 After the state switching slot 6213, it is blocked by the stop limiter 625 and cannot continue to move. At this time, if the external force disappears, the return spring 41 will force the inner chuck 611 to fall back, and when it falls, it cannot return to the use chute 6215, but enters the use rest slot 6223 by switching the landslide 6221. When the inner card table 611 is located in the use stationary slot 6223, it is in the use state at this time. When the rear penholder assembly and the front rod 1 are squeezed by an external force, the inner chuck 611 enters the state switching groove 6213 again, and enters the recovery curved groove 6214 by not using the switching slope 624. At this time, if the external force disappears, the return spring 41 will force the inner chuck 611 to fall again, and when it falls, it cannot return to the state switching groove 6213, but returns to the unused resting area 6212 through the recovery curved groove 6214. When the external force is generated again, repeat the above operation.

Example 3:

As shown in Figures 1 to 4 and 16 to 19, a barrel repositioning pen includes a front rod 1, a rear pen rod assembly, a pen core 4, a return spring 41, an adjusting inner rotation member 47 and a reset movement. The return spring 41 and the pen core 4 are both located in the rod body of the front rod 1, and the return spring 41 is specifically clamped between the pen core 4 and the front rod 1. The return spring 41, the refill 4 and the reset movement are sequentially installed in the front rod 1, and the tail end of the refill 4 conflicts with the reset movement. The above-mentioned reset movement is engaged with the front rod 1 so that it is not easy to get out of the front rod 1, thereby forming a positive pressure elastic force reset pen.

The above-mentioned positive pressure elastic force reset pen has two forms, namely the in-use state and the non-in-use state. The specific differences, the process of form transformation and the principle of form change are as follows:

The specific difference is that: in the state of use, the tip of the pen core 4 remains exposed at this time. In the unused state, the tip of the pen core 4 is hidden in the front rod 1 at this time.

The principle of shape change is mainly determined by the reset movement, and the principle of the reset movement is as follows:

The reset movement is at least composed of a fixed shell and an internal displacement device, and there are at least two morphological changes with a stable positional relationship between the internal displacement device and the fixed shell. The specific position and form change into a short fit and a long fit. The difference between the distance between the bottom end of the fixed case of the reset movement and the top of the internal displacement device in the above-mentioned short fit and the distance between the bottom end of the fixed case of the reset movement and the top of the internal displacement device in the long fit The value is equal to the difference between the exposure of the refill 4 and the retracted front rod 1.

Morphological transformation process:

1. When in use, the reset movement is in a short fit state. At this time, the internal displacement device is closer to the core hole of the front rod 1, and the specific distance is the total length of the refill 4 minus the total length of the refill 4 in the use state. The distance to expose the core hole.

2. When not in use, the reset movement is in a long fit state. At this time, the internal displacement device is closer to the core hole of the front rod 1. The specific distance is the total length of the refill 4 plus the refill in the unused state. 4 When the pen tip is hidden in the front rod 1, the distance from the core hole.

The other end of the above-mentioned reset movement is screwed into the adjusting inner rotating member 47. The front rod 1 is partially sleeved in the rear barrel assembly. The inner adjusting member 47 is screwed to the inner end of the rear penholder assembly. Then, the rear penholder assembly is assembled by adjusting the inner rotation member 47 and the positive pressure elastic force reset pen, so that it can be operated in reverse. The rear penholder assembly can be clamped by the tiger's mouth part of the hand, and then the index finger and middle finger clamp the front end of the front rod 1 to move it closer to the tiger's mouth, so that the length of the reset movement can be switched, thereby switching its correctness. Squeeze the elastic force to reset the matching form of the pen.

The above-mentioned reset movement includes an inner sleeve 71, a pusher 72 and a rotating inner core 73. The inner sleeve 71 is equal to the fixed shell. The above-mentioned rotating inner core 73 is equal to the above-mentioned internal displacement device.

The inner sleeve 71 is a hollow sleeve, and a plurality of supporting protrusion rods 711 are provided inside. The end of the supporting protrusion 711 is provided with a closed ring protrusion 74. A movable straight groove 713 is also provided between the supporting protrusion rods 711 and a conversion slope 7111 is provided at the front end of the supporting protrusion rod 711. The rear end of the propelling member 72 is provided with an external thread, the external thread is matched with the internal thread of the adjusting inner rotating member 47, and the front end is provided with a sliding block 721 and a propulsion guide protruding protrusion 722 in the same number as the support protruding rod 711. The propulsion guide Propelling guide slopes 7221 are provided on both sides of the pointed protrusion 722. The end of the rotating inner core 73 is provided with two fitting bosses 732 that are not in contact with each other and leave a gap. The top end of the engagement boss 732 is also provided with a card protrusion 7321, and the middle end is provided with a switching boss 731 of the same number as the supporting boss 711. There is a support gap between the switching bosses 731, and the supporting boss 711 slides on In the supporting gap, the above-mentioned switching boss 731 is provided with a use guide slope 7311 and a release guide slope 7312. A use card slot 733 is formed between the above use guide slope 7311 and the release guide slope 7312. The propelling member 72 is also provided with an anti-seizing protrusion 723. The front end of the rotating inner core 73 and the tail end of the pen core 41 conflict with each other.

The rotating inner core 73 is inserted into the pushing member 72 through the engagement boss 732 and the locking projection 7321. After the locking projection 7231 passes through the anti-separation locking projection 723, it is not easy to detach, and the assembly of the rotating inner core 73 and the pushing member 72 is completed. At this time, the assembled rotary propelling member is inserted into the inner sleeve 71 from bottom to top with the closed ring protrusion 74 of the inner sleeve 71 as the upper side.

When not in use, the above-mentioned switching boss 7311 is located in the movable straight groove 713. By squeezing the propelling member 72, the propelling guide slope 7221 will continue to interfere with the use of the guide slope 7311. At this time, the use of the guide slope 7311 and the propulsion guide slope 7221 are in a semi-contact state, and the rotating inner core 73 is forced to move up continuously. After the switching boss 731 is out of the mating range of the movable straight groove 713, the above-mentioned use guide slope 7311 fully cooperates with the propulsion guide slope 7221, which forces the rotating inner core 73 to rotate to a certain extent, so that the use guide slope 7311 and the conversion slope The 7111 has a half contact. When the pusher 72 is released, the force of the return spring 41 will cause the rotating inner core 73 to reset. At this time, the guide slope 7311 has already made half contact with the conversion slope 7111. Therefore, it will directly cause the rotating inner core 73 to spin further, so that the switching boss 731 is stuck on the top end of the supporting protrusion 711. At this time, it is in the short-fitting state, that is, the in-use state, and the nib of the pen core 4 remains exposed to the front rod 1. status,

At this time, if the propelling member 72 is pressed again, the advancing guide slope 7221 at this moment will continue to interfere with the disengaging guide slope 7312. At this time, the advancing guide slope 7221 and the disengaging guide slope 7312 are in a semi-contact state, and Forcing the rotating inner core 73 to move up continuously, when the switching boss 731 is out of the mating range of the movable straight groove 713, the above-mentioned disengagement guide slope 7312 fully cooperates with the propulsion guide slope 7221, and the rotating inner core 73 is forced to undergo a certain range. It rotates, so that the use guide slope 7311 is out of the conflict of the conversion slope 7111, and the release guide slope 7312 has half contact with the conversion slope 7111. When the pusher 72 is released, it is affected by the return spring 41. The force will cause the propelling member 72 to reset, but at this time the release guide slope 7312 has already made half contact with the conversion slope 7111, so it will directly cause the rotating inner core 73 to spin further, so that the switching boss 731 separates from and supports the protruding rod. After the collision of 711, it slides into the movable straight groove 713 again, and it is in the long-fitting state at this time, that is, the state is not in use, and the pen tip remains retracted in the front rod 1.

As a further preference, a pushing spring 74 is further provided between the inner sleeve 71 and the adjusting inner rotating member 47. The above-mentioned pushing spring is used to separate the rear penholder assembly from the positive pressure elastic force reset pen. Because, when the switching boss 731 is stuck on the top end of the support protruding rod 711, at this time, the pusher 72 is in any up and down movable state in the movable straight groove 713, and the pusher 72 is one of the rear penholder assembly and the positive pressure elastic reset pen. When the pusher 72 is in any up and down movement state, the rear penholder assembly and the positive pressure elastic force reset pen will sway randomly. The addition of the push spring 74 can prevent the rear penholder assembly and the positive pressure elastic force reset pen. Shake up and down randomly to make it more stable in use and meet people's needs.

The specific differences between the embodiments are explained:

1. Due to the use of embodiment 3, the pusher will slide up and down at will. Although the push spring ensures the stability between the rear penholder assembly and the positive pressure elastic return pen, it also results in whether it is in use and In the unused state, the mating distance between the rear penholder assembly and the positive-pressure elastic reset pen remains unchanged; therefore, no matter whether it is in use or not, the pen of Example 3 does not look at the tip of the pen core from the appearance There is no change in appearance if it is exposed or not;

2. As in 1, the embodiment 3 is compared with the embodiment 1 and the embodiment 2, under the same structure, without a writing sleeve, the range that can be held during writing will be smaller than that of the embodiment 1 and the embodiment 2; because, the embodiment When 1 and Example 2 are in use, the reset mechanism is in a short-distance state, and the distance between the external rear penholder assembly and the positive pressure elastic force reset pen will also be shortened; then the rear penholder assembly and the positive pressure elastic force reset pen will be shorter. The matching degree between the two will be higher, and the matching degree between the bamboo joint outer rod and the bamboo joint inner rod will be higher, and the length that can be provided for the grip will be increased.

3. Both Embodiment 2 and Embodiment 3 must be disassembled and assembled in sequence; because their structures are all rigid designs, adopting the mode of ring-to-ring phase; while in embodiment 1, the sliding movement of the movement can be reset by pulling out. The reset cylinder and the reset telescopic rod are separated, so that the engagement bending platform can be separated from the unused slot.

Further additions:

In the above three embodiments, a tail cap 46 and a hook 45 can be added to the tail of the rear pen barrel assembly. The hook 45 and the rear pen barrel assembly are sleeved with each other. The tail cap 46 is inserted into the rear pen barrel assembly to cover the adjustment inner Rotating member 47. The above-mentioned adjusting inner rotating member 47 can be used to adjust the mating distance between the positive pressure elastic reset pen and the rear penholder assembly, that is, the total length of the two after mating; when there is no writing sleeve, it can be used to adjust the outer rod of the bamboo joint and The degree of fit of the inner rod of the bamboo joint is the length of the grip part; the appearance effect can also be adjusted.

For Example 3, there is also the adjustment of the elastic force value of the push spring between the positive pressure elastic force reset pen and the adjusting inner rotating member. The longer the length of the push spring, the squeezing of the positive pressure elastic force reset pen and the rear penholder assembly. The smaller the pressure required.

In addition, it should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for the sake of clarity, and those skilled in the art should regard the specification as a whole The technical solutions in the various embodiments can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
