Description

Writing end movable volume closed marking tool Technical Field

[0001] The present invention relates to the structure of a marking tool, in particular to a marking tool with a movable roll-up type writing end that is free of pen caps and provides airtightness. Background Art

[0002] The current writing instrument market is generally divided into two categories: solid marking tools (such as pencils) and liquid marking tools. The chemical pigments used in liquid marking tools are generally divided into four types: oil-based, neutral, water-based, and volatile. With the exception of oil-based chemical pigments, which are relatively stable, the other three types will evaporate over time after contact with the atmosphere. Therefore, in order to maintain the chemical pigments for a longer period of time and prevent them from evaporating or drying out, liquid marking tools generally use pen caps to tightly seal the writing end or incorporate airtight structures inside the pen caps to prevent contact with the atmosphere outside the pen caps. However, pen caps are often lost, forgotten, damaged, or inconvenient to use, causing the nibs of writing instruments to dry out and clog, resulting in significant waste. For example, pens using volatile inks, such as markers, whiteboard markers, and paint pens, as well as water-based inks, such as signature pens, rollerball pens, colored pens, highlighters, gel pens, fountain pens, and writing brushes, can quickly become clogged and dry due to prolonged exposure to the atmosphere. To address the inconvenience of using caps for these liquid marking tools over a long period of time, as well as the nibs' clogging caused by the evaporation and drying of pigments due to exposure to the atmosphere, a new type of marking tool is highly desirable.

The mating structure 40 is primarily used to securely connect one end of the movable scroll 50. The mating structure 40, the positioning structure 30, and the ink tube 203 can be integrally formed. In one embodiment, they are three separate components.

[0109] A movable scroll 50 is a flexible ring-shaped structure 503 having two bendable ends 501 and 502. The movable scroll 50 is made of a flexible and elastic material. The material can be made of soft and stretchable rubber, rubber composite, plastic, plastic composite, latex, latex composite, or other flexible and stretchable materials.

[0110] A marker pen tip 60, which can be composed of a liquid writing pen tip (for example, a liquid writing pen tip such as a ballpoint pen tip, a fountain pen tip, a fiber pen tip, an animal hair pen tip, a fiber brush tip, and other pen tips capable of storing liquid pigments, etc.), and one embodiment uses a fiber pen tip 601 as an example;

[0111] Please refer to the assembly status shown in Figures 2 to 7. First, please refer to Figure 2, in which the hollow barrel-shaped 1013 of the upper rod 101 of the rod body assembly 10 and the hollow shape 1023 of the lower rod 102 have the built-in marking assembly 20, and are connected to each other by the connecting portion 304 at one end 301 of the positioning structure 30 and the fitting portion 1014 at one end of the upper rod 101. The fitting portion 1014 and the connecting portion 304 can be fitted with each other by tight fitting, snapping, locking, fitting, gluing, fusion and other structures, and this embodiment adopts locking as the fitting method of the two. An airtight rubber ring A can also be added between the two as needed, so that the upper rod 101 can be removed from the positioning structure 30 as needed to replace the ink tube 203, and the ink pigment can be locked in an airtight manner to prevent the volatilization of the ink.

[0112] The movable scroll 50 has one end 501 positioned at an appropriate position 1025 of the hollow 1023 near one end 1022 of the lower rod 102 by means of a tight ring Z, and the other end 502 is positioned on the positioning groove 402 of the engagement structure 40. The end 501 of the movable scroll 50 can be integrally formed with the tight ring Z or separated, and the present embodiment adopts a separated shape; in addition, the tight ring Z can also adopt a structure such as tight fit, snap fit, locking, sleeve fit, gluing, fusion or integral molding, and be placed on the lower rod 10 2 is located at an appropriate position 1025 of the hollow space 1023 near one end 1022. In this embodiment, the tightening ring Z adopts a separate tight fit and a buckle method to fix the one end 501 of the movable reel 50 to the appropriate position 1025 of the lower rod 102. In addition, the other end 502 of the movable reel 50 and the fitting structure 40 can also be placed at an appropriate position of the fitting structure 40 by a tight fit, buckle, lock, sleeve fit, glue, fusion or integral molding structure. However, in this embodiment, a separate tight fit method is adopted.

[0113] The movable scroll 50 operates as shown in FIG3 and FIG4 , by utilizing a flexible annular structure 503 having two ends 501 and 502 that can be bent and stretched elastically. One end 501 of the movable scroll 50 is placed around the outer periphery of the tight ring Z, and then the other end 502 is placed on the appropriate portion 402 of the engagement structure 40 for positioning. The engagement structure 40 is engaged with one end 302 of the positioning structure 30 to position the one end 501 of the movable scroll 50. The engagement of the engagement structure 40 with the one end 302 of the positioning structure 30 can be achieved by tight fitting, snap-fitting, locking, fitting, gluing, fusion, or integral molding. However, in this embodiment, a separate tight fitting method is used for fixation. The edges of the two ends 501 and 502 of the movable scroll 50 can be designed as geometric flanges 504 to facilitate positioning.

[0114] Referring to FIG. 5 , the lower rod 102 and the positioning structure 30 are capable of relative movement and rotation S1 , and the movable roll 50 is capable of bending and elastically stretching, thereby forming a rolled-up, enclosed space B. This allows the writing tip 60 to be enclosed within the airtight space B, or the movable roll 50 to be unrolled to open the airtight space B.

[0115] 6 and 7 , the movable mechanism design enables the marker tip 60 of the present invention to have a roll-up function that can be sealed or extended to open, thereby preventing the liquid ink from evaporating and drying up without the need for a pen cap seal. This is the main purpose of this embodiment for recording purposes after long-term storage.

[0116] Please refer to Figure 8, which shows a second embodiment of a marking tool with a movable roll-up end provided by the present invention. The lower rod 102 of the rod assembly 10 and the positioning structure 30 can be moved relative to each other by pulling the lower rod 102 straight to a specific position of the positioning structure 30, and then tightening the screw 305 on the screw 1026 provided at one end 1021 of the lower rod 102. During the tightening process, the lower rod 102 and the positioning structure 30 will twist the movable roll 50 to cover the writing pen tip 60 to form a rolled closed space B, thereby creating an airtight effect there and preventing the ink in the writing pen tip 60 from evaporating and drying up.

[0117] In the third embodiment shown in Figures 9 and 10, the lower rod 102 of the rod assembly 10 and the positioning structure 30 can be moved relative to each other by mutually providing spiral tracks. The spiral tracks can be designed as concave or convex spiral tracks. In this embodiment, a convex spiral track D is designed to rotate in conjunction with the concave spiral track D1 of the lower rod 102. By means of the convex spiral track D, when the lower rod 102 is rotated on the positioning structure 30 toward the writing tip 60, the movable coil 50 is twisted to form a coiled, enclosed space B that can cover the writing tip 60, creating an airtight effect therein, thereby preventing the ink in the writing tip 60 from evaporating and drying out.

[0118] In addition, in order to allow the lower rod 102 to have the function of being positioned at a specific position of the positioning structure 30, specially designed concave and convex snap groups E1 and E2 are respectively arranged at the two ends 301 and 302 near the positioning structure 30 and the matching position of the lower rod 102. When the lower rod 102 is moved to the position of the concave and convex snap group E1, the lower rod 102 will be stuck on the convex snap group E1 (as shown in Figure 9). At this time, the movable scroll 50 has not yet been rolled out of the enclosed space B and is in an open state; and when the lower rod 102 is rotated downward toward the writing pen tip 60 and moved to the position of the convex snap group E2 (as shown in Figure 10), the movable scroll 50 will be stretched and twisted out of the rolled-up enclosed space B and cover the writing pen tip 60, creating an airtight effect there, thereby preventing the liquid ink in the writing pen tip 60 from evaporating and drying up from there.

[0119] As shown in the fourth embodiment of FIG11 , a segmented tooth rail D2 may be used to reduce the friction of the spiral rail D provided in the positioning structure 30 , so that the positioning structure 30 is smoother during rotation and twisting, wherein the number of segments of the segmented tooth rail D2 may be one or more as needed.

[0120] Please refer to FIG12, which shows a fifth embodiment of a marking tool with a movable winding end provided by the present invention. In order to allow the winding closed space B formed by the movable winding body 50 to stably cover the writing pen tip 60, in addition to designing the concave and convex buckle groups E1 and E2, a set of snap assembly F can also be used to position the lower rod 102 relative to the positioning structure 30. The snap assembly F is composed of a pressure piece F1 and an elastic body F2. The pressure piece F1 has two ends F11 and F12, and is provided with a locking protrusion F13 at one end F12 and a fixed position. The fixed position can be By one or more holes, grooves, recesses, notches and other conventional technologies, and the present embodiment is implemented with a positioning hole F14, the positioning hole F14 borrows a bolt G, respectively penetrates in the positioning hole F14 and the lower rod 102 near one end thereof provided for a positioning protrusion 1027 of an axis hole, and by a spring F2 disposed between the pressure piece F1 and the outer wall of the lower rod 102, so that the pressure piece F1 produces a lever effect, so that the positioning protrusion F13 can be stuck into the position of the trapezoidal recess 305 of the positioning mechanism 30 and then positioned. When the positioning of the lower rod 102 and the positioning mechanism 30 is to be unlocked, one end F11 of the pressure piece F1 can be pressed;

[0121] The snap fastener assembly F may also adopt other conventional hands-free snap fastener technologies (such as a spring convex buckle assembly F15 and a convex buckle F16 similar to the concave-convex buckle assembly E1, E1 of the third embodiment) to achieve the same locking purpose, which is within the scope of this embodiment.

[0126] Referring to Figures 21 to 26, FIG. 21 shows a thirteenth embodiment of the present invention, which provides a movable roll-closed marking tool with a writing end. The marking tool includes a rod assembly A10 comprising an upper rod A101, a lower rod A102, a positioning structure A30, a mating structure A40, a movable roll body A50, a middle joint A70, and a rotating mechanism A80.

[0127] A rod assembly A10, consisting of an upper rod A101 and a lower rod A102;

[0128] An upper rod A101 having two ends A1011 and A1012 in a hollow shape A1013. At least one slide rail or a spiral rail may or may not be provided in the hollow shape A1013. The slide rail and the spiral rail may be designed as concave or convex spiral rails. In this embodiment, the concave spiral rail AD3 is designed. A mating portion A1014 and A1015 are provided at each end of the upper rod A101. The mating portions A1014 and A1015 may be mated with related components by tight fit, snap fit, locking, sleeve fit, gluing, fusion or integrally formed structures. In this embodiment, a locking method is used to engage with a positioning cap X and a middle joint A70. A slot 1016 and A1017 are provided at each proximal end of the upper rod A101.

[0129] A lower rod A102 also has two ends A1021 and A1022 in a hollow A1023 shape. At least one slide rail or one spiral rail may or may not be provided in the hollow A1023. The slide rail and the spiral rail may be designed as a concave or convex spiral rail, and the present embodiment is designed as a concave spiral rail AD4. In addition, a connecting portion A1024 is provided at one end A1021 of the lower rod A102. The connecting portion A1024 may be connected to related components by a tight fit, a snap fit, a locking fit, a gluing fit, a fusion fit or an integrally formed structure, and the present embodiment adopts a snap fit method with the middle connection A70. The snap fit method may utilize a U-shaped groove to form a snap fit group AU1 in the shape of an inverted hook, and on the lower rod A102 At least one buckle assembly AU1 is provided at one end A1021, and in this embodiment, four inverted hook buckle assemblies AU1 are provided. The inverted hook portion AU11 of the inverted hook buckle assembly AU1 can generate elasticity due to the shape of the U-shaped groove. Therefore, when one end A1021 of the lower rod A102 is inserted into the corresponding hook groove A704 of the middle connection A70 through the buckle assembly AU1, it can be locked into place. This design is mainly to provide the upper rod A101 or the lower rod A102 with a mutually non-detachable movable rotation on the middle connection A70. The buckle assembly AU1 can also be provided at the two ends A1011 and A1012 of the upper rod A101, one end A1021 of the lower rod A102, or the two ends A701 and A702 of the middle connection A70, etc., as needed.

[0130] A middle joint A70 has two hollow ends A701, each end of which is provided with a fitting portion A702, A703. The fitting portions A702, A703 can be fitted with the upper rod A101 and the lower rod A102 by means of a tight fit, snap fit, locking, sleeve fit, gluing, fusion, or integrally formed structure. In this embodiment, a snap fit is used as the fitting method. The snap fit is provided with a hook groove A704 to provide a fitting connection for one end of the upper rod A101 or the lower rod A102. In this embodiment, a snap fit is provided with a snap fit assembly AU1 on one end A102 of the lower rod A102.

[0131] A positioning structure A30 is an axially penetrating shape A303 with two ends A301 and A302. The axial aperture of the penetrating shape A303 can be the same or multiple different sizes. In this embodiment, two sizes are designed to form a T-shaped hole A306, so that a writing ink tube can be placed there and limited. The periphery of the positioning structure A30 may or may not be provided with one or more spiral rails. The spiral rails can be designed as concave or convex spiral rails. In this embodiment, a convex spiral rail AD5 is designed to rotate in conjunction with the concave spiral rail AD4 of the lower rod A102. In addition, a mating portion A307 is provided at one end A302 of the positioning structure A30. The mating portion A307 can be connected to the relevant components by a tight fit, snap fit, locking, sleeve fit, gluing, fusion, or integral molding structure. In this embodiment, locking is used as the mating method.

[0132] A keying structure A40, which is generally geometric in shape and has at least one slot A401 and a positioning ladder groove A402;

[0133] A movable scroll A50, in the form of a flexible ring-shaped structure A503 having two elastically stretchable ends A501 and A502. The movable scroll A50 is made of an elastic, stretchable, and bendable material, such as rubber or a rubber composite, plastic or a plastic composite, latex or a latex composite, silicone or a silicone composite, or other bendable, stretchable, and extendable materials.

[0134] A turning mechanism A80 is in the shape of a hollow groove A803 with two ends A801 ​​and A802. At least one spiral track may be provided or not provided on its outer edge. The spiral track can be designed as a concave or convex spiral track. In this embodiment, a convex spiral track AD6 is designed to rotate in conjunction with the concave spiral track AD3 of the upper rod A101. The turning mechanism A80 may or may not be provided with positioning structures A804 and A805 at appropriate locations of the two ends A801 ​​and A802. The positioning structures A804 and A805 are composed of at least one concave or convex ring, point, or The structure is composed of grooves and other geometric shapes, and this embodiment uses multiple protrusions A806 and A807 to surround the edges of the two ends A801 ​​and A802, and the open ends of the two ends A801 ​​and A802 are provided with elastic grooves A808 and A809, which provide the protrusions A806 and A807 with a retracted space when they are snapped with the upper rod A101, so that they can be firmly positioned or moved after jumping off. The elastic grooves A808 and A809 can also be provided with a notch Y on the periphery of the protrusions A806 and A807 to replace or change the elastic force.

[0135] Referring to the assembly method shown in Figures 22 and 23, first, one end A502 of the movable reel A50 is positioned on one end A302 of the positioning structure A30 via the engagement structure A40. Then, one end A501 of the movable reel A50 is placed outside the tight ring Z and inserted together into the hollow A1023 near the end A1022 of the lower rod A102. At this time, the movable reel A50 can be fixed in position via the tight ring Z, while the positioning structure A30 can be spirally moved relative to each other via the concave and convex spiral rails AD4 and AD5.

[0136] The upper rod A101 is connected to the lower rod A102 via the middle joint A70. The end of the lower rod A102 connected to the middle joint A70 is provided with a hook snap assembly AU1, which allows the middle joint A70 to forcibly interlock with the hook groove A704 and the hook portion AU11, so that the middle joint A70 can be formed on the end A1022 of the lower rod A102 and rotate in place without being separated from the end. The middle joint A70 and the end A1022 of the lower rod A102 can also adopt a conventional structure of mutual movable connection without separation or an additional component assembly to achieve the same effect.

[0137] Select the desired ink cartridge A20 and install it into the rod assembly A10 and the middle joint A70. Insert the writing tip A60 through the end A302 of the positioning structure A30, the joint structure A40, and the core hole A1024 at the end A1022 of the lower rod A102, exposing it to the writing surface. Next, insert the transfer mechanism A80 into the end of the ink cartridge using the hollow groove A803 and position it. Finally, lock the transfer mechanism A80 onto the end A1011 of the upper rod A101 with the positioning cap X to prevent it from exiting the rod assembly A10.

[0138] Referring to the usage state shown in Figures 23 and 24, when the pen tip A60 of the present invention is stored in the rod assembly A10 and activated, the upper rod A101 only needs to be rotated (as indicated by the elliptical arrow). This rotation causes the rotation mechanism A80 mounted on the concave spiral track AD3 to begin rotating via the convex spiral track AD6. The rotation mechanism A80 will use the elastic groove A808 to cause the protrusion A806 to retract radially inward, leaving the groove A1016 of the upper rod A101, and continue to rotate toward the end A1022 of the lower rod A102. At the same time, the ink tube A20 is also pushed to move, and the movement of the ink tube A20 will in turn push the positioning structure A30 to move along with it. The positioning structure A30 will use its own convex spiral track AD5 to dock and move with the concave spiral track AD4 of the lower rod A102, causing the positioning structure A30 to rotate and move. At the same time, the movable coil A50, which has been bent, will be unscrewed from the enclosed space B, gradually releasing the sealed state of the pen tip A60 at one end of the ink tube A20 and extending it out of the core hole A1024 at one end of the lower rod A102 to provide writing.

[0139] To ensure that the extended end A1022 of the ink tube A20 is securely used, the end A802 of the rotating mechanism A80 serves the same function as the end A801. A protrusion A807 is provided. When the rotating mechanism A80 is rotated to the set position, the protrusion A807 engages with the groove A1017 of the end A1022 of the upper rod A101.

[0140] The elastic groove A808, protrusions A806, A807 of the turning mechanism A80 and the locking grooves A1016, A1017 of the upper rod A101, etc. may all be optional structures and may be provided or not provided as needed.

[0141] When the pen tip A60 is to be retracted into the rod assembly A10, the upper rod A101 is rotated in the opposite direction to rotate the hollow tube A803 tightly fitted in the rotating mechanism A80 and the ink tube A20 tightly fitted in the through-hole A303 of the positioning structure A30 into the rod assembly A10, thereby storing the pen tip A60 inside. As the positioning structure A30 retracts into the rod assembly A10, the movable coil A50 is curled to form a closed space B, thereby enclosing the pen tip A60. This isolates the pen tip A60 from the outside atmosphere, creating an airtight effect. As shown in Figures 23 and 24, the pen tip A60 can be used repeatedly, achieving the goal of eliminating the need for a pen cap and effectively avoiding waste by enclosing the pen tip A60 to prevent ink from drying up at the pen tip A60.

[0142] Please refer to the method of replacing the ink tube A20 shown in Figure 25. First, open the positioning cap X and then rotate the upper rod A101 to remove the transfer mechanism A80. Then, remove the ink tube A20 from the rod assembly A10 and replace it. The ink tube A20, the transfer mechanism A80, and the positioning structure A30 are all in a detachable tight fit. Because of the tight fit between the three parts, when the upper rod A101 is rotated, the transfer mechanism A80 and the positioning structure A30 can drive the ink tube 20 through the spiral track to provide replacement. The ink tube 20 and the transfer mechanism A80 are tightly fitted. The ink tube 20, the rotating mechanism A80, and the positioning structure A30 can be removably fitted together, and can be positioned by means of tight fitting, snapping, locking, sleeve fitting, gluing, bonding, magnetic attraction, or concave-convex structures. Alternatively, the ink tube 20, the rotating mechanism A80, and the positioning structure A30 can be integrally formed to reduce production costs. In this embodiment, a concave-convex positioning structure W is used with a removable tight fitting as a keying method. Alternatively, the upper rod A101 can be removed from the portion where it connects to A70 to replace the ink tube 20.

[0143] Regarding this embodiment, the concave spiral rails AD3 and AD4 of the upper rod A101 and the lower rod A102, and the convex spiral rail AD6 of the turning mechanism A80 and the convex spiral rail AD5 of the positioning structure A30 can be used in pairs or separately according to design requirements. For example, only the upper rod A101 and the turning mechanism A80 are equipped with the concave spiral rail AD3 and the convex spiral rail AD6, while the lower rod A102 and the positioning structure A30 do not need to be equipped with spiral rails; conversely, only the lower rod A102 and the positioning structure A30 are equipped with the concave spiral rail AD4 and the convex spiral rail AD5, while the upper rod A102 and the turning mechanism A80 do not need to be equipped with spiral rails; or the upper rod A101, the lower rod A102, the turning mechanism A80 and the positioning structure A30 are all equipped with spiral rails. This choice is conducive to the selection of multiple categories of products of the present invention.

[0144] Please refer to Figures 26 and 27. The fourteenth embodiment of the present invention provides a marking tool with a movable writing end and a closed type. Based on the thirteenth embodiment, in particular, the positioning structure A30 has a coarse diameter portion A308 and a thin strip diameter portion A309 of different diameters, wherein the thin strip diameter portion A309 faces the direction of one end A1022 of the lower rod A102, and a coil spring A90 is additionally provided on the thin strip diameter portion A309. The coil spring A90 has two ends A901 and A902, and one end A901 presses against the thin strip diameter portion A309. The other end A902 of the coil spring A90 rests on an edge Z1 of the tightening ring Z, forming a trapezoidal portion between the upper rod A101 and the larger diameter portion A308. The purpose of the coil spring A90 is to allow the positioning structure A30 to return to a specific position after being adjusted to the appropriate position toward the end A1022 of the lower rod A102. This facilitates replacement of the ink tube 20 during rotation of the upper rod A101, facilitates better resetting of the positioning structure A30 and the movable scroll A50, and also facilitates the design of the present invention as a basic reciprocating mechanism for automatic pressing.

[0145] Please refer to Figures 26 and 27 again, which show a writing end movable roll-closed marking tool provided by the fifteenth embodiment of the present invention, wherein in addition to the spiral rail, the mutual movement of the turning mechanism A80 and the upper rod A101 according to the thirteenth and fourteenth embodiments of the present invention can also adopt at least one straight rail on the inner wall of the hollow A1013 of the upper rod A101, and the present embodiment adopts two opposed straight rails, which can be designed as convex rails or concave rails, and the present embodiment adopts the concave rail AD7, and the turning mechanism A80 and the upper rod A101 can move relative to each other. The relative position of the matching rod is also provided with at least one slide rail or convex slider AD8, and the present embodiment adopts two convex sliders AD8, so that when the upper rod A101 is rotated by external force (as shown by arrow S), the turning mechanism A80 is rotated, and the positioning structure A30 in the lower rod A102 is rotated to drive the writing assembly to be rotated out or in the direction of the lower rod core, so that the movable scroll A50 opens the closed space B and exposes the pen tip A60 to provide writing (as shown in Figure 27), or the movable scroll A50 is curled into the closed space B to repeatedly wrap the pen tip A60 (as shown in Figure 26).

[0146] Referring to Figures 28, 29, and 30, a retractable writing end marking tool is provided. Based on the thirteenth, fourteenth, and fifteenth embodiments, the rod assembly A10 of the present invention has a minimalist, slender overall appearance (as shown in Figures 28 and 29). Furthermore, the same cap-free pen body, which prevents liquid ink from drying out, can be used with various types of pens that require isolation from atmospheric contact (as shown in Figure 30). The thirteenth and fourteenth embodiments can respectively use various ink cartridges N20 with matching ink and pen tips, such as gel pens and ballpoint pens (Series A), rollerball pens (Series B), signature fiber pens (Series C), markers and highlighters (Series D), and other liquid pens.

[0147] Referring to FIG. 31 , the sixteenth embodiment of the present invention provides a marking tool with a movable winding end. This embodiment employs a nib assembly A602. The nib assembly A602, including the nib and tongue, is assembled onto a positioning mechanism A30 to form an integral unit. The ink tube A20 utilizes a card-type refill ink tube A203. This card-type refill ink tube A203 can be a conventional ink tube for pens, such as a suction-type, card-type, or other ink tubes for pens. However, this embodiment utilizes a card-type ink tube from a common fountain pen. Furthermore, to prevent the nib S from contacting the movable winding body A50, a sleeve sheet A403 is added to the engagement structure A40. The sleeve sheet A403 is provided with a tongue-shaped sheet A404 extending toward the tip of the nib. The sleeve sheet A403 can be an independent part or integrally formed with some components of the nib assembly A602, and extend close to the nib. In this way, the movable scroll A50 can be prevented from contacting the sleeve sheet A403 and becoming an ink conductor, so that the airtight space B formed by the movable scroll A50 can avoid ink accumulation. This sleeve sheet A403 can be implemented around the writing nib in the above various implementations; the pressing ring Z can be tightly matched, snapped, locked, fitted, glued, adhered, magnetically attracted, and the concave and convex structures can be positioned with each other, and the present embodiment uses a locking method to position the movable scroll A50 in the hollow shape A1023 at one end A1022 of the lower rod A102.

[0148] Please refer to Figures 32 and 33. The seventeenth embodiment of the present invention provides a writing end movable roll-closed marking tool. In particular, the fourteenth embodiment of the present invention is used to design the present invention into an automatic pressing mechanism with a reciprocating mechanism. The rod assembly B10 is designed as a long rod B103 with two ends B1031 and B1032 in the shape of an axial hollow through-hole B1033, and is provided with a button B104. The button B104 also has two ends B1041 and B1042 and is provided with a hollow groove B1043. A coil spring B90 has two ends B901 and B902. The middle end B901 presses against the trapezoidal portion BT formed by the connection between the thin strip-shaped opening B309 and the thick opening B308 of the positioning structure B30, and the other end B902 of the coil spring B90 rests on an edge Z1 of the tight ring Z. Preferably, the end B902 of the spring B90 engages with the hole wall B1034 of the axial hollow through-hole B1033 in the proximal end B1032 of the long rod B103. Other methods of tight fit, snap fit, locking, sleeve fit, concave-convex structure, or using another part for positioning can also be used for mutual positioning. In this embodiment, another part, the tight ring Z, is used for positioning.

[0149] The purpose of spring B90 is to allow the positioning structure B30 to be rotated toward the end B1032 of the long rod B103 to move to the appropriate position. This allows the positioning structure B300 to be elastically reset to a specific position, thereby providing the present invention with a basic reciprocating mechanism for automatic pressing. The automatic pressing and locking mechanism of the present invention can be implemented using a conventional pen-pressing mechanism or a jumping structure, which will not be described in detail here.

[0150] When in use, one only needs to press the button B104 to allow the writing tip B60 of the ink tube B20 positioned in the slot B104 to cooperate with the positioning structure B30, and move through the spiral track of the axial hollow through-hole B1033 of the long rod B103, thereby turning open the airtight space B formed by the movable scroll B50, allowing the writing tip B60 to extend out of the core hole B1024 for use; in addition, the positioning cap BX on one end B1031 of the long rod B103 can be opened and the button B104 can be removed to replace the ink tube B20.

The connecting portion BH3 can be completed by a locking, perforation, or a conventional movable fitting structure. In this embodiment, a positioning bolt BH4 is used to pass through a perforation BH5 on the side of the connecting portion BH3 and a protrusion B1035 on the proximal end B1031 of the long rod B103 that cooperates with it, thereby positioning the locking pen clip BH in this position to generate a lever effect. A spring BH7 is provided in the groove BH6 at one end BH1 of the locking pen clip BH, and a locking protrusion BH8 is provided at the other end BH2. The locking protrusion BH8 can be inserted into the through groove B1036 provided for matching with the long rod B103, so that the locking protrusion BH8 is locked on the structure provided for matching with the internal parts of the long rod B103. The structure can be a protrusion, a groove, a ladder groove or a geometric structure. In this embodiment, the ladder groove B1045 provided on the button B104 is used as a matching mechanism. In addition to providing a positioning mechanism for the relevant components matching with it in the long rod B103, the above embodiment also allows the above embodiment to have the function of carrying the present invention on clothing.

[0153] Please refer to Figure 38 for a writing end movable roll-up marking tool provided in the twenty-second embodiment of the present invention. In order to provide appropriate protection for the peripheral edge B60A of the core outlet portion of the fiber pen tip in the above embodiments, an annular structure K is added to cover it. The annular structure K can be set independently or integrally formed with the ink tube B20, or integrally formed with the positioning structure B30 and placed; when the nib B60 of the ink tube B20 is extended out of the pen barrel for use, the annular structure K can protect the peripheral edge B60A of the core outlet portion of the nib B60 from being damaged by the force of the pen barrel core outlet B1024.

[0154] Please refer to Figures 39, 40, 41 and 42 for a writing end movable roll-closed marking tool provided by the twenty-third, twenty-fourth and twenty-fifth embodiments of the present invention. The movable roll bodies 50, A50 and B50 of the above embodiments are designed with several structural solutions to make the airtight space B formed by the movable roll bodies more conducive to storing the pen tip B60. The node L of the movable roll body X50 is adjusted to change the storage space B to accommodate pen tips with different writing functions.

[0155] As shown in the twenty-third embodiment of Figures 39 and 40, the movable scroll assembly X50 has two ends X501 and X502, one end X502 of which is provided with a tightening portion X5021, and the tightening portion X5021 is geometrically shaped. In this embodiment, a ring-shaped structure is used to be tightly sleeved on the groove X3021 near one end X302 of the positioning structure X30 of the writing assembly X20 (as shown in Figure 40), wherein the writing assembly X20 can be composed of an independent pen core, or a pen core formed integrally with the positioning structure X30; the other end X501 of the movable scroll assembly X50 can be positioned in the axial hollow through-hole B1033 at one end of the pen shaft assembly by a positioning ring Z (as shown in the above embodiments) or be integrally formed with the positioning ring Z, and one end X501 thereof is connected to any position of the positioning ring Z, and in this embodiment, it is connected to one edge Z11 of the positioning ring Z, and can also be connected to the other edge Z12 of the positioning ring Z (as shown in the twenty-fourth embodiment of Figure 41);

[0156] In addition, as shown in Figures 39 and 40, the wall thickness of the roll assembly X50 can also be designed to extend from thick to thin in the shape of X503. This is beneficial for the roll assembly X50 to be set to a preset position through the bendable material properties, thereby generating a volume change in the storage space B. Similarly, the tightening portion X5021 at one end X502 of the roll assembly X50 can also be designed as a geometric part, so that the one end X502 can use the structural bending to change the storage space B of the roll assembly X50 (as shown in the twenty-fifth embodiment of Figure 42).
