Description

Technical Field

[0001] The present invention relates to the field of writing tools, and particularly to a push-button writing tool. Background Art

[0002] Currently, after a user finishes writing with a push-button pen and needs to retract the refill, the user has to press the push button of the push-button pen to retract the refill. This way of retracting the refill is relatively single, and the operation also results in a poor user experience, so that after writing, the user is prone to forgetting to retract the refill. Summary of the Invention

[0003] The purpose of the present invention is to provide a push-button writing tool to increase the ways for a user to choose to retract the refill during the writing process, thereby improving the user experience during writing.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: A push-button writing tool, which includes: a pen barrel extending axially and a refill radially received in the pen barrel; a first push body supported in the pen barrel in a manner of axially moving back and forth within a range between an initial position and a first position relative to the rear side of the pen barrel, and an end of the first push body is exposed outside the pen barrel for axial pressing operation; a second push body elastically supported in the pen barrel in a manner of radially moving within a range between a protruding position and a pressing position relative to the side surface of the pen barrel, and a side portion of the second push body is exposed outside the pen barrel for radial pressing operation; a telescopic spring acting between the pen barrel and the refill and used to act on the refill contrary to the axial pressing operation of the first push body; a runner connected to the refill and cooperating with the first push body and the second push body. When the first push body is axially pressed forward to the first position against the action of the telescopic spring and axially pushes the runner to rotate forward, the runner is locked in a locked state. In the locked state, the runner is axially positioned relative to the pen barrel, and the refill protrudes from the front end of the pen barrel. When the runner is in the locked state and the first push body is axially pressed again and moves forward to the first position and axially pushes the runner to rotate forward, the runner is released from the locked state and can axially move relative to the pen barrel, and the refill retracts into the pen barrel under the action of the telescopic spring; or, after the second push body moves radially inward to the pressing position, the runner is released from the locked state and can axially move relative to the pen barrel, and the refill retracts into the pen barrel under the action of the telescopic spring.

[0005] It can be understood that by setting the end of the first push body to be exposed outside the pen barrel, the first push body can be controlled to move within the range of the initial position and the first position of the pen barrel during use, thereby driving the rotation of the rotating wheel, so as to protrude the refill from the front end of the pen barrel or retract the refill into the pen barrel. And by setting the side of the second push body to be exposed outside the pen barrel, the second push body can be controlled to move within the range of the protruding position and the pressing position on the side of the pen barrel during use. Then, when the refill protrudes from the front end of the pen barrel, by moving the second push body radially inwards to the pressing position, the rotating wheel is released and the refill is retracted into the pen barrel. This push-type writing tool includes two types of push bodies, and each push body is set at different positions on the pen barrel, which is convenient for users to choose a suitable way to retract the refill into the pen barrel during the process of using this push-type writing tool for writing, thereby improving the user experience during writing.

[0006] Furthermore, the push-type writing tool further includes: a lining, sleeved on the radial outer side of the rotating wheel and fixed to the pen barrel; when the first push body moves forward to the first position and pushes the rotating wheel to rotate forward, the rotating wheel abuts against the lining to lock the rotating wheel in a locked state; when the rotating wheel is in the locked state, the second push body moves radially inwards to the pressing position to release the abutment between the rotating wheel and the lining and release the rotating wheel from the locked state.

[0007] It can be understood that by sleeving the lining on the outside of the rotating wheel, when the rotating wheel advances to the first position, it abuts against the lining, thereby locking the state of the rotating wheel, so that the refill maintains the state of protruding from the front end of the pen barrel, and improving the writing durability of this push-type writing tool.

[0008] Furthermore, the second push body includes a button holder provided at its bottom, and the button holder is adapted to radially pass through the lining to press the rotating wheel.

[0009] Furthermore, the push-type writing tool further includes an elastic member acting between the button holder and the lining; an elastic member positioning rib provided at the bottom of the second push body and surrounding the button holder for limiting the elastic member.

[0010] It can be understood that by setting the elastic member positioning rib at the bottom of the second push body and surrounding the button holder, the elastic member acting on the button holder and the lining can be in a state of abutting against the elastic positioning rib, positioning the position of the elastic member, and preventing the problem of damage to the push-type writing tool caused by the falling off of the elastic member during the assembly of the push-type writing tool.

[0011] Furthermore, the lining is provided with a through hole, the through hole is aligned with the second push body, and there are a plurality of limiting members at the through hole for limiting the pressing position of the button holder on the rotating wheel.

[0012] It can be understood that by providing a plurality of limiting members at the through holes of the inner liner to limit the pressing position of the button holder passing through the through holes, the accuracy of the second pressing member in pressing the pressing position is improved.

[0013] Furthermore, the push-type writing tool further includes: a plurality of bosses provided on the inner surface of the inner liner; a plurality of elastic hangers circumferentially arranged on the outer surface of the runner; when the first pressing body moves forward to the first position and pushes the runner to rotate forward, the bosses and the elastic hangers abut against each other, thereby locking the runner in a locked state; when the second pressing body moves radially inward to the pressing position, the button holder pushes the runner, so that the elastic hanger is disengaged from abutting against the boss, and the runner is released from the locked state.

[0014] It can be understood that by cooperating the bosses provided on the inner surface of the inner liner with the elastic hangers provided on the outer surface of the runner, when the runner rotates forward, the bosses and the elastic hooks abut against each other to prevent the runner from advancing excessively, thereby improving the durability of the push-type writing tool.

[0015] Furthermore, the plurality of bosses include three bevel bosses and one right-angle boss, and the bevel bosses and the right-angle boss are circumferentially arranged on the inner surface of the inner liner at equal intervals together; the plurality of elastic hangers include four elastic hooks and four first jumping ribs, and the elastic hooks and the first jumping ribs are circumferentially arranged on the outer surface of the runner at equal intervals respectively, and the elastic hooks and the first jumping ribs are axially corresponding in position; when the first pressing body moves forward to the first position and pushes the runner to rotate forward, one of the four elastic hooks abuts against the right-angle boss to prevent the runner from axially moving, and the first jumping rib abuts against the bevel boss to limit the rotation of the runner in the first direction; when the second pressing body moves radially inward to the pressing position, the elastic hook is driven by the second pressing body to be disengaged from abutting against the right-angle boss and can thus axially move.

[0016] It can be understood that the bevel bosses and the right-angle boss cooperate with the elastic hooks and the first elastic ribs. When pushing the runner to rotate forward, the right-angle boss abuts against the elastic hook, and the bevel boss abuts against the first jumping rib, cooperating with each other to stabilize the position of the runner and improve the durability of the push-type writing tool.

[0017] Furthermore, four first guide grooves and four second guide grooves are provided on the inner surface of the pen barrel near the first pressing body; four first guide ribs and four second guide ribs are provided on the outer surface of the first pressing body, and the first guide grooves and the second guide grooves, and the first guide ribs and the second guide ribs are circumferentially staggered and evenly distributed respectively, the first guide ribs correspond to the first guide grooves, the second guide ribs correspond to the second guide grooves, and the first guide ribs and the second guide ribs are adapted to cooperate with the first guide grooves and the second guide grooves to limit the axial rotation of the first pressing body.

[0018] It can be understood that by providing at least one first guiding groove and at least one second guiding groove on the inner surface of the pen barrel, it is convenient for the first pressing body to be assembled into the pen barrel along the corresponding guiding grooves through the first guiding ribs and the second guiding ribs on the outer surface, thereby improving the convenience of installing the push-type writing tool. At the same time, the guiding ribs and the guiding grooves correspond to each other, which can fix the first pressing body and reduce the problem of malfunctions of the push-type writing tool caused by the movement of the first pressing body during the use of the push-type writing tool.

[0019] Further, the end of the first pressing body close to the runner has eight guide rails; on the surface of the runner close to the first pressing body, there are four second jumping ribs, and the second jumping ribs correspond to the first guiding groove. The second jumping ribs have inclined surfaces at the ends close to the first pressing body, and the inclined surfaces are adapted to cooperate with the guide rails so that the runner rotates relative to the first pressing body during the process of the first pressing body pushing the runner forward. And the first guiding groove and the second guiding groove have guiding groove inclined surfaces at the top ends close to the runner, and the inclined surface of the first pressing body is also adapted to cooperate with the guiding groove inclined surfaces of the first guiding groove or the second guiding groove so that the runner rotates relative to the pen barrel during the process of the runner retracting.

[0020] When the first pressing body moves forward to the first position and pushes the runner to rotate forward, while one of the four elastic hooks abuts against the right-angle boss, the second jumping rib abuts against the side surface of the first guiding groove to limit the runner from rotating in the second direction opposite to the first direction.

[0021] When the first pressing body moves forward to the first position again and pushes the runner to rotate forward, one of the four elastic hooks disengages from the abutment with the right-angle boss, the first jumping rib disengages from the abutment with the beveled boss, the second jumping rib disengages from the abutment with the side surface of the first guiding groove, and during the process of the runner retracting, the inclined surface of the second jumping rib cooperates with the guiding groove inclined surfaces of the first guiding groove or the second guiding groove to make the runner rotate relative to the pen barrel, and the refill is retracted into the pen barrel.

[0022] Further, when the runner is in the locked state, when the first pressing body is axially pressed again and moves forward to the second position closer to the initial position than the first position and axially pushes the runner to rotate forward, releasing the first pressing body will cause the runner to rotate under the combined action of the elastic restoring force of the telescopic spring and the guiding of the beveled surface of the beveled boss on the first jumping rib, so that the runner is released from the locked state and can axially move relative to the pen barrel, thereby retracting the refill into the pen barrel.

[0069] As Figure 1As shown, the push-type writing tool 100 includes: a pen barrel 10, a refill 20, a first push body 30, a second push body 40, a telescopic spring 80, and a rotating wheel 50. Among them, the pen barrel 10 has a traditional axially extending hollow structure, the refill 20 is radially received in the pen barrel 10, the first push body 30 is supported in the pen barrel 10 in such a way that it moves axially back and forth within a range between an initial position and a first position relative to the rear side of the pen barrel 10, and the end of the first push body 30 is exposed outside the pen barrel 10 for axial pressing operation. The second push body 40 is elastically supported in the pen barrel 10 in such a way that it moves radially within a range between a protruding position and a pressing position relative to the side surface of the pen barrel 10, and the side portion of the second push body 40 is exposed outside the pen barrel 10 for radial pressing operation. The telescopic spring 80 acts between the pen barrel 10 and the refill 20 and acts on the refill 20 contrary to the axial pressing operation of the first push body 30. The rotating wheel 50 (for example, at the front end portion) is connected to the refill 20.

[0070] In one embodiment, the pen barrel 10 may have a structure assembled from multiple components. For example, the pen barrel 10 may include two parts, a pen body 11 and a pen neck 12. The pen body 11 and the pen neck 12 may be connected and installed to each other through a threaded groove at the end or other (such as magnetic attraction) means. The present application is not limited thereto.

[0071] In one embodiment, when the first push body 30 is in the initial position, the degree of exposure of the first push body 30 outside the pen barrel 10 is greater than the degree of exposure of the first push body 30 outside the pen barrel 10 when the first push body 30 is in the first position.

[0072] The shape of the part of the first push body 30 exposed outside the pen barrel 10 may be arched or square, and the shape of the part of the second push body 40 protruding from the side surface of the pen barrel 10 may also be arched, square, etc. By setting the parts of the first push body 30 and the second push body 40 exposed outside the pen barrel 10 to be arched or square, it is convenient for the user to press the first push body 30 and the second push body 40.

[0073] Preferably, the sizes of the first push body 30 and the second push body 40 can also be set according to the size of the user's palm.

[0074] Exemplarily, the sizes of the first push body 30 and the second push body 40 can be divided into three sizes: large, medium, and small to correspond to the palm sizes of adults, teenagers, and children.

[0075] Furthermore, the position where the second push body 40 protrudes from the side surface of the pen barrel 10 can be at the middle position of the pen barrel 10 or at the position of the pen barrel 10 close to the first push body 30. Considering that when the user uses the push-type writing tool 100, the hand is usually held at the position near the pen tip at the front end of the pen barrel 10, this setting can prevent the user from accidentally touching the second push body 40 when using the push-type writing tool 100, thus avoiding the problem of inconvenient use and improving the smoothness of the user using the writing tool for writing.

[0076] Furthermore, the push-type writing tool 100 further includes a telescopic spring 80. The outer surface of the front end of the refill 20 has a flange extending outward. The two ends of the telescopic spring 80 respectively act on the flange and the inner surface of the pen barrel 10 near the front end. The rotating wheel 50 has a abutting surface (not shown) for abutting against the rear end of the refill 20 to connect with the refill 20.

[0077] It can be understood that by arranging the telescopic spring 80 to act between the flange of the refill 20 and the inner surface of the pen barrel 10 near the front end, when the rotating wheel 50 is pushed to rotate forward, the rotating wheel 50 can push the refill 20 through its abutting surface to protrude from the front end of the pen barrel 10 against the elastic force of the telescopic spring 80. When the rotating wheel 50 is released, the refill 20 loses the abutment of the rotating wheel 50, and thus the refill 20 is retracted into the pen barrel 10 under the elastic force of the telescopic spring 80.

[0078] When the first push body 30 moves forward to the first position and axially pushes the rotating wheel 50 to rotate forward, the rotating wheel 50 will be locked in a locked state. In this locked state, the rotating wheel 50 remains positioned relative to the pen barrel 10, and the refill 20 protrudes from the front end of the pen barrel 10 for writing. When the rotating wheel 50 is in the locked state, by axially pressing the first push body 30 to move it forward to the first position again and pushing the rotating wheel 50 to rotate forward, the rotating wheel 50 will be released from the locked state and can axially move relative to the pen barrel 10, and the refill 20 is retracted into the pen barrel 10 under the action of the telescopic spring 80. Or, by radially pressing the second push body 40 to move it radially inward to the pressing position, the rotating wheel 50 can also be released from the locked state and can axially move relative to the pen barrel 10, and the refill 20 is retracted into the pen barrel 10 under the action of the telescopic spring 80.

[0079] It can be understood that by setting the end of the first pressing body 30 to be exposed outside the pen barrel 10, the first pressing body 30 can be controlled to move within the range of the initial position and the first position of the pen barrel 10 during use, thereby driving the rotation of the rotating wheel 50, so as to protrude the refill 20 from the front end of the pen barrel 10 or retract the refill 20 into the pen barrel 10. And by setting the side part of the second pressing body 40 to be exposed outside the pen barrel 10, the second pressing body 40 can be controlled to move within the range of the protruding position and the pressing position on the side of the pen barrel 10 during use. Further, when the refill 20 protrudes from the front end of the pen barrel 10, by moving the second pressing body 40 radially inwards to the pressing position, the rotating wheel 50 is released and the refill 20 is retracted into the pen barrel 10. The push-type writing tool 100 includes two types of pressing bodies, and each pressing body is arranged at different positions of the pen barrel 10, which is convenient for the user to select a suitable way to retract the refill 20 into the pen barrel 10 during the process of using the push-type writing tool 100, thereby improving the user experience during writing.

[0080] Please refer to Figures 2 to 5 , in the embodiment of the present application, the push-type writing tool 100 further includes a lining 60, and the lining 60 is sleeved outside the rotating wheel 50 and fixed to the pen barrel 10.

[0081] When the first pressing body 30 moves forward to the first position and pushes the rotating wheel 50 to rotate forward, the rotating wheel 50 abuts against the lining 60 to lock the rotating wheel 50 in the locked state. When the rotating wheel 50 is in the locked state, the second pressing body 40 moves radially inwards to the pressing position to release the abutment between the rotating wheel 50 and the lining 60 and release the rotating wheel 50 from the locked state.

[0082] It can be understood that the lining 60 is sleeved outside the rotating wheel 50, so that when the rotating wheel 50 advances to the first position, it abuts against the lining 60, thereby locking the rotating wheel 50 to keep the refill 20 in the state of protruding from the front end of the pen barrel 10, and improving the writing durability of the push-type writing tool 100.

[0083] Further, please refer to Figures 6 to 9 , a positioning groove 104 can be formed on the inner surface of the pen barrel 10, and the positioning groove 104 is used to fix the lining 60.

[0084] The style of the positioning groove 104 can be determined according to the styles of the pen barrel 10 and the lining 60. Preferably, when both the pen barrel 10 and the lining 60 are cylindrical, the positioning groove 104 can be a V-shaped positioning groove 104, and the lining 60 can have a V-shaped positioning rib 63 matching the V-shaped positioning groove 104. The lining 60 is fixed to the pen barrel 10 by embedding the V-shaped positioning rib 63 into the V-shaped positioning groove 104 of the pen barrel 10.

[0085] It can be understood that the inner liner 60 is installed through the positioning groove 104 on the inner surface of the pen barrel 10 to fix the position of the inner liner 60 within the pen barrel 10, facilitating the installation of the push-type writing tool 100, and at the same time improving the durability of the push-type writing tool 100, avoiding damage caused by the movement of the inner liner 60 within the pen barrel 10.

[0086] Please refer to Figure 10 , the second push body 40 includes a button holder 41 provided at its bottom, and the button holder 41 is adapted to pass through the inner liner 60 to press the rotating wheel 50.

[0087] Preferably, the button holder 41 can be a button holder structure with a square through hole on the side.

[0088] In one embodiment, the push-type writing tool 100 further includes an elastic member 70 and an elastic member positioning rib 71. The elastic member 70 acts on the button holder 41 and the inner liner 60 respectively, and the elastic member positioning rib 71 is provided at the bottom of the second push body 40 and surrounds the button holder 41 for limiting the elastic member 70.

[0089] Furthermore, the elastic member 70 can be a return spring, and the elastic member positioning rib 71 can be an open-type positioning rib or a non-open-type positioning rib, such as a C-type positioning rib and an O-type positioning rib, etc. The elastic member positioning rib 71 is provided between the button holder 41 and the elastic member 70. Among them, the outer surface shape of the elastic member positioning rib 71 is adapted to the inner surface shape of the elastic member 70, and one end of the elastic member 70 close to the elastic member positioning rib 71 abuts against the elastic member positioning rib 71.

[0090] It can be understood that by arranging the elastic member positioning rib 71 at the bottom of the second push body 40 and surrounding the button holder 41, the elastic member 70 acting on the button holder 41 and the inner liner 60 can be in a state of mutual abutment with the elastic member positioning rib 71, positioning the position of the elastic member 70, and preventing damage to the push-type writing tool 100 caused by the detachment of the elastic member 70 during the assembly of the push-type writing tool 100.

[0091] In one embodiment, the longitudinal width of the bottom of the button holder 41 is smaller than the longitudinal width of the body of the button holder 41.

[0092] Preferably, the bottom of the button holder 41 can be a trapezoidal structure or the like.

[0093] It can be understood that by setting the bottom of the button holder 41 to have a longitudinal width smaller than that of the body of the button holder 41, the force required to press the second push body 40 is reduced, facilitating the passage of the second push body 40 through the inner liner 60 to press the rotating wheel 50 and release the rotating wheel 50.

[0094] Furthermore, please refer to again Figures 2 to 7, the inner lining 60 is provided with through holes which are aligned with the second pressing body 40, and there are a plurality of limiting components 61 at the through holes for limiting the pressing position of the button holder 41 pressing the rotating wheel 50.

[0095] Furthermore, the through holes on the inner lining 60 can be H-shaped through holes, and the limiting components 61 can be elastic sheets. By arranging the elastic sheets at the H-shaped through holes, the pressing position of the H-shaped through holes for the button holder 41 to press the rotating wheel 50 is further improved. At the same time, since the limiting components 61 are elastic sheets, compared with non-elastic limiting components, the wear generated when the button holder 41 contacts the limiting components 61 can be reduced.

[0096] It can be understood that by arranging a plurality of limiting components 61 at the through holes of the inner lining 60 to limit the pressing position of the button holder 41 passing through the through holes, the accuracy of the second pressing body 40 pressing the pressing position is further improved.

[0097] Please refer to again Figures 2 to 5 and Figure 11 and Figure 12 , the push-type writing tool 100 further includes a plurality of bosses 62 and elastic hanging parts 51. Each boss 62 is arranged on the inner surface of the inner lining 60, and the elastic hanging parts 51 are arranged around the outer surface of the rotating wheel 50.

[0098] When the first pressing body 30 moves forward to the first position and pushes the rotating wheel 50 to rotate forward, the boss 62 and the elastic hanging part 51 abut against each other. When the second pressing body 40 moves radially inward to the pressing position, the button holder 41 pushes the rotating wheel 50 to disengage the elastic hanging part 51 from the boss 62.

[0099] It can be understood that by matching the boss 62 arranged on the inner surface of the inner lining 60 with the elastic hanging part 51 arranged on the outer surface of the rotating wheel 50, when the rotating wheel 50 rotates forward, the boss 62 and the elastic hanging part 51 cooperate with each other.

[0100] In the embodiment of the present application, the boss 62 includes three bevel bosses 621 and one right-angle boss 622, and the elastic hanging part 51 includes four elastic hooks 511 and four first jumping ribs 512. The bevel bosses 621 and the right-angle boss 622 are arranged around the inner surface of the inner lining 60 at equal intervals together, while the elastic hooks 511 and the first jumping ribs 512 are both arranged around the outer surface of the rotating wheel 50 at equal intervals together, and the elastic hooks 511 and the first jumping ribs 512 are axially corresponding. The bevel boss 621 has a bevel at its end close to the pen tip for guiding the first jumping rib 512 to rotate in the same direction as the guide rail 33 of the first pressing body 30.

[0101] When the first pressing body 30 moves forward to the first position and drives the rotating wheel 50 to rotate forward, the elastic hook 511 crosses the right-angled boss 622 and abuts against the right-angled boss 622 to prevent the rotating wheel 50 from axially moving backward. At this time, the first jumping rib 512 also abuts against the bevel boss 621 to prevent the rotating wheel 50 from rotating in the first direction.

[0102] When the second pressing body 40 moves radially inward to the pressing position, the elastic hook 511 is driven to disengage from the right-angled boss 622, and the rotating wheel 50 can axially move, so that the first jumping rib 512 can also disengage from the bevel boss 621.

[0103] Preferably, the right-angled boss 622 can be arranged in the inner surface of the inner liner 60 near the area penetrated by the button holder 41, and the bevel boss 621 can be arranged at the end of the inner liner 60 close to the first jumping rib 512.

[0104] It can be understood that the bevel boss 621 and the right-angled boss 622 respectively cooperate with the first jumping rib 512 and the elastic hook 511. After the rotating wheel 50 is driven to rotate forward, the right-angled boss 622 abuts against the elastic hook 511, and the bevel boss 621 abuts against the first jumping rib 512, and they cooperate with each other to stabilize the position of the rotating wheel 50.

[0105] In an embodiment, four first guiding grooves 101 and four second guiding grooves 102 are formed in the inner surface of the pen barrel 10 near the first pressing body 30, and four first guiding ribs 31 and four second guiding ribs 32 are formed on the outer surface of the first pressing body 30. These guiding grooves and guiding ribs are evenly distributed in the circumferential direction. Among them, the first guiding rib 31 corresponds to the first guiding groove 101, the second guiding rib 32 corresponds to the second guiding groove 102, and the first guiding rib 31 and the second guiding rib 32 cooperate with the first guiding groove 101 and the second guiding groove 102 to limit the rotation of the first pressing body 30.

[0106] Furthermore, the difference between the first guiding groove 101 and the second guiding groove 102 can be the inconsistent depth of the grooves. The widths of the grooves can also be inconsistent to avoid the first guiding groove 101 and the second guiding groove 102 from cooperating with the wrong first guiding rib 31 and second guiding rib 32 during assembly.

[0107] It can be understood that by axially arranging four first guide grooves 101 and four second guide grooves 102 on the inner surface of the pen barrel 10, it is convenient for the first pressing body 30 to be assembled into the pen barrel 10 along the corresponding guide grooves through the first guide ribs 31 and the second guide ribs 32 on the outer surface, thereby improving the convenience of installing the push-type writing tool 100. At the same time, the guide ribs and the guide grooves correspond to each other, which can circumferentially fix the first pressing body 30 and reduce the problem of the failure of the push-type writing tool 100 caused by the movement of the first pressing body 30 during the use of the push-type writing tool 100. Moreover, the number of the first guide grooves 101 and the second guide grooves 102 can be adjusted according to needs. However, it should be noted that the guide rails 33 and the guide ribs 31 / 32 on the first pressing body 30, the elastic hanging parts 51 and the second jumping ribs 52 on the runner 50 may also need to be adjusted accordingly, which is clear to those skilled in the art.

[0108] Further, please refer to Figure 13 and Figure 14 , the end of the first pressing body 30 close to the runner 50 has eight guide rails 33, and four second jumping ribs 52 are provided on the surface of the runner 50 close to the first pressing body 30.

[0109] Further, the end face of the second jumping rib 52 close to the first pressing body 30 is an inclined surface, which is used to contact the guide rail 33 of the first pressing body 30 and the guide groove inclined surface 103 at the top close to the runner 50 of the first guide groove 101 and the second guide groove 102 on the pen barrel 10 respectively, so as to make the runner 50 rotate when the runner 50 moves axially relative to the first pressing body 30 and the pen barrel 10.

[0110] When the first pressing body 30 moves forward to the first position and pushes the runner 50 to rotate forward, the second jumping rib 52 abuts against the side surface of the first guide groove 101 to limit the rotation of the runner 50 in the second direction opposite to the first direction. That is to say, the runner 50 is axially positioned by the right-angle boss 622 and circumferentially positioned by the bevel boss 621 and the side surface of the first guide groove 101, so that the runner 50 is stably locked in the locked state, and the user can write in this state. When the first pressing body 30 moves forward to the first position again and pushes the runner 50 to rotate forward, one of the four elastic hooks 511 is disengaged from the right-angle boss 622, the first jumping rib 512 is disengaged from the bevel boss 621, the second jumping rib 52 is disengaged from the side surface of the first guide groove 101 or the second guide groove 102, and the end inclined surface of the second jumping rib 52 cooperates with the guide groove inclined surface 103 of the first guide groove 101 or the second guide groove 102 during the backward movement of the runner 50 to make the runner 50 rotate relative to the pen barrel 10, and the refill 20 is retracted into the pen barrel 10.

[0111] Further, each guide rail 33 of the first pressing body 30 has an inclined surface extending generally circumferentially, and the guide rails 33 together form an annular ratchet-like structure.

[0112] In a preferred embodiment, the tops of the first guide groove 101 and the second guide groove 102 in the pen barrel 10 have inclined surfaces in the same direction as the guide rails 33, that is, the guide groove inclined surfaces 103, for causing the runner 50 to rotate by contacting the inclined surfaces of the second jumping ribs 52.

[0113] The following will fully describe the process of the push-type writing tool 100 extending the refill 20 from the front end of the pen barrel 10 and retracting the refill 20 into the pen barrel 10 through the first pressing body 30.

[0114] Please refer to Figure 14 and Figure 15 When the first pressing body 30 is pressed from the initial position to the first position, since the telescopic spring at the front end of the pen barrel 10 abuts against the boss 62 on the refill 20, the refill 20 is limited at the front end of the pen barrel 10 and the first pressing body 30 cannot be further pressed. During this process, the second jumping rib 52 on the original runner 50 and the first guide groove 101 or the second guide groove 102 on the pen barrel 10 are displaced. At this time, the inclined surface on the second jumping rib 52 on the runner 50 is stressed by the guide rail 33 on the first pressing body 30, causing the guide rail 33 to rotate axially, and the second jumping rib 52 of the runner 50 is caught in the lowest point of the inclined surface of each guide rail 33 of the first pressing body 30.

[0115] At this time, the pressing of the first pressing body 30 is stopped. Under the action of the telescopic spring 80, the first pressing body 30 starts to retract. During the retraction process, the end inclined surface of the second jumping rib 52 contacts the guide groove inclined surface 103 of the first guide groove 101 or the second guide groove 102 of the pen barrel 10, causing the runner 50 to start to rotate axially.

[0116] Further, the side of the second jumping rib 52 on the runner 50 is adapted to abut against the side of the first guide groove 101 or the second guide groove 102 of the pen barrel 10 to prevent the runner 50 from rotating in the second direction (for example, counterclockwise compared to itself). At the same time, the side of the first jumping rib 512 on the runner 50 is adapted to abut against the side of the beveled boss 621 on the inner liner 60 to prevent the runner 50 from rotating in the first direction opposite to the second direction (for example, clockwise compared to itself), thereby realizing the rotational locking of the runner 50. At this time, the push-type writing tool 100 is in a writing state, and the elastic hook 511 on the runner 50 abuts against the right-angle boss 622 on the inner liner 60.

[0117] Further, when the first push body 30 is pressed again, the inclined surface of the second jumping rib 52 on the rotating wheel 50 contacts the guide rail 33 on the first push body 30, and they are translated forward along the pen barrel 10 together under the pressure of the first push body 30. At this time, the side of the first jumping rib 512 on the rotating wheel 50 is separated from the side of the beveled boss 621 on the inner liner 60, and the rotating wheel 50 starts to rotate axially. At this time, the first jumping rib 512 does not contact other components, the inclined surface of the second jumping rib 52 on the rotating wheel 50 contacts the guide rail 33 of the first push body 30, and the rotating wheel 50 can rotate relative to the first push body 30. Furthermore, the second jumping rib 52 is snapped into the lowest point of the guide rail 33 of the first push body 30.

[0118] Further, when the inclined surface of the second jumping rib 52 on the rotating wheel 50 is stuck at the lowest point of the guide rail 33 of the first push body 30, during the backward movement of the rotating wheel, the second jumping rib 52 contacts the tops of the first guide groove 101 and the second guide groove 102 on the pen barrel 10. Under the action of the telescopic spring, the rotating wheel 50 will start to rotate axially. At this time, the elastic hook 511 on the rotating wheel 50 is separated from the right-angled boss 622 on the inner liner 60, and the rotating wheel 50 and the first push body 30 are reset.

[0119] It should be noted that the above process is the first way to press the first push body 30 to retract the refill 20 into the pen barrel 10. That is, by pressing the first push body 30 to move a relatively long distance (about 7-8 mm) to reach the first position, so that the second jumping rib 52 on the rotating wheel 50 fully cooperates with the guide rail 33 of the first push body 30 (that is, the second jumping rib 52 moves to the lowest point of the guide rail 33), the rotating wheel 50 rotates, and the rotating wheel 50 is released.

[0120] In another embodiment, the first push body 30 can be pressed to move a relatively short distance (about 2-3 mm) to reach the second position. That is, the second position is closer to the initial position than the first position, and the second jumping rib 52 does not fully cooperate with the guide rail 33 of the first push body 30 (that is, the second jumping rib 52 does not move to the lowest point of the guide rail 33). The rotating wheel 50 turns slightly so that the first jumping rib 512 on the rotating wheel 50 can contact the inclined surface of the beveled boss 621 on the inner liner 60. After releasing the first push body 30, the rotating wheel 50 rotates under the combined action of the elastic restoring force of the telescopic spring 80 and the guidance of the inclined surface of the beveled boss 621, thereby releasing the rotating wheel 50.

[0121] Next, the process of retracting the refill 20 into the pen barrel 10 by pressing the second push body 40 is described.

[0122] When the push-type writing instrument 100 is in a writable state, the elastic piece at the through-hole of the inner liner 60 is snapped into the through-hole of the button holder 41, and the elastic hook 511 on the runner 50 abuts against the right-angled boss 622 on the inner liner 60. At this time, when the second push body 40 is pressed and moves radially inwards to the pressing position, the bottom of the button holder 41 contacts the surface of the elastic hook 511 on the runner 50 and applies a force thereto, causing the elastic hook 511 on the runner 50 to disengage from the right-angled boss 622 on the inner liner 60, thereby directly releasing the runner 50 from the locked state and retracting the refill 20 into the pen barrel 10 to achieve the reset of the refill 20.

[0123] Specifically, when the second pressing body 40 is pressed, the elastic hook 511 on the runner 50 disengages from the right-angled boss 622 on the inner liner 60. At this time, the inclined surface on the second jumping rib 52 on the runner 50 contacts the guiding groove inclined surface 103 of the first guiding groove 101 or the second guiding groove 102 on the pen barrel 10, and the runner 50 starts to rotate axially. After the second jumping rib 52 on the runner 50 contacts the side surface of the first guiding groove 101, the runner 50 stops rotating. At this time, under the action of the telescopic spring 80, the runner 50, the first push body 30 and the refill 20 are pushed to complete the reset.
