Description

Technical Field

[0001] This utility model relates to the technical field of stationery, and more specifically to a rotating lead-out pen. Background Technology

[0002] Existing automatic ballpoint pens or automatic gel pens generally involve pressing the cap to automatically extend or retract the pen tip, but this lacks fun and fails to provide emotional value to users, resulting in low vitality for the automatic gel pen category. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotating pen with decorative parts and a pen tip at both ends of the pen barrel, and a rotating part connected to both the decorative parts and the pen tip in the middle of the pen barrel. By rotating the rotating part, the tips of the decorative parts and the pen tip can be extended out of the pen barrel or retracted into the pen barrel at the same time, which increases the fun and allows users to obtain emotional value during operation, thereby enhancing the vitality of the ballpoint pen category.

[0004] The technical solution of this utility model is to provide a rotating pen with a refill tip, including a pen barrel. A rotating component is disposed inside the pen barrel, and the pen barrel axially limits the rotating component. An operation window is disposed on the side wall of the pen barrel, and an operation part is disposed on the rotating component opposite to the operation window. The operation part can move left and right within the operation window to drive the rotating component to rotate left and right within the pen barrel. An upper guide and a lower guide are slidably connected to the upper and lower ends of the rotating component, respectively. The pen barrel circumferentially limits both the upper and lower guides. Rotation of the rotating component can cause the upper and lower guides to slide in opposite directions along the length of the pen barrel. A decorative component is disposed at the upper end of the upper guide and a pen refill is disposed at the lower end of the lower guide. The upper and lower guides can respectively drive the decorative component and the pen refill to move in opposite directions, so that the tips of the decorative component and the pen refill extend or retract simultaneously from the top and bottom ends of the pen barrel, respectively.

[0005] Compared with existing technologies, the rotating tip-out pen of this utility model has the following advantages: It changes the traditional method of automatic pens where the tip extends or retracts by pressing the cap. By moving the operating part left and right within the operating window, it drives the rotating component to rotate left and right within the pen barrel. This drives the upper and lower guide components to slide in opposite directions along the length of the pen barrel, allowing the decorative part and the tip of the tip to simultaneously extend or retract from the barrel, increasing the fun. The decorative part can be designed in the shape of a heart or other popular cartoon doll characters, or customized to a user's favorite doll character, providing emotional value during operation and enhancing the vitality of the automatic ballpoint pen category. The rotating component is axially limited, allowing only circumferential movement, preventing it from interfering with the vertical movement of the upper or lower guide components. The upper and lower guide components are also circumferentially limited, allowing only vertical movement, preventing interference with the rotation of the rotating component. This allows for effective operation of the operating part, enabling the decorative part and the tip of the tip to simultaneously extend or retract from the top and bottom of the pen barrel, respectively, avoiding ineffective operation.

[0006] Preferably, the lower part of the upper guide member is sleeved on the upper part of the rotating member, or the upper part of the rotating member is sleeved on the lower part of the upper guide member. An upper elastic member is provided between the upper guide member and the pen barrel, and the lower end of the upper elastic member is connected to the upper guide member. At least one spiral-shaped first guide step surface is provided on the side wall where the rotating member connects to the upper guide member. A first sliding protrusion corresponding to the first guide step surface is provided on the side wall where the upper guide member connects to the rotating member. The first sliding protrusion is slidably connected to the corresponding first guide step surface. When the rotating member rotates forward, it drives the first sliding protrusion to slide upward along the first guide step surface, causing the upper guide member to rise and the upper elastic member to be compressed. When the rotating member rotates in reverse, the upper elastic member rebounds and drives the first sliding protrusion to slide downward along the first guide step surface, causing the upper guide member to descend. This structure is simple and allows the rotation of the rotating member to smoothly cause the upper guide member to rise or fall.

[0007] Preferably, a first locking position is provided at the upper end of the first guide step surface. The first locking position is a groove structure with the slot facing upward. When the rotating component rotates forward, it drives the first sliding protrusion to slide upward along the corresponding first guide step surface into the first locking position, thereby locking the upper guide component at its highest height. When the rotating component rotates in reverse, the upper elastic rebound drives the first sliding protrusion to move downward and disengage from the first locking position, unlocking the upper guide component. With this structure and the first locking position, it is beneficial to keep the decorative component stationary after it extends out of the pen barrel, avoiding accidental force on the decorative component that could cause the rotating component to reverse, and preventing accidental force on the decorative component that could cause it to retract into the pen barrel.

[0008] Preferably, a first limiting stop is provided at the upper end of any one of the first guide step surfaces on the rotating component. When there is only one first guide step surface, the two side walls of the first limiting stop are the upper and lower end stops of the first guide step surface, respectively. When there are two or more first guide step surfaces, any one of the first limiting stops is located between two adjacent first guide step surfaces, with one side wall of the first limiting stop serving as the upper end stop of one of the first guide step surfaces and the other side wall serving as the lower end stop of the other first guide step surface. The side walls of the first limiting stops, acting as stops, are used to limit the movement of the first sliding protrusion. This structure helps to prevent the first sliding protrusion from disengaging from the first guide step surface due to excessive rotation of the rotating component.

[0009] Preferably, the upper part of the lower guide member is sleeved on the lower part of the rotating member, or the lower part of the rotating member is sleeved on the upper part of the lower guide member. A lower elastic member is provided between the lower guide member or the pen refill and the pen barrel, and the upper end of the lower elastic member is connected to the lower guide member or the pen refill. At least one spiral second guide step surface is provided on the side wall where the rotating member connects to the lower guide member, and a second sliding protrusion corresponding to the second guide step surface is provided on the side wall where the lower guide member connects to the rotating member. The second sliding protrusion is slidably connected to the corresponding second guide step surface. When the rotating member rotates forward, it drives the second sliding protrusion to slide downward along the second guide step surface, causing the lower guide member to descend and the lower elastic member to be compressed. When the rotating member rotates in reverse, the lower elastic member rebounds and drives the second sliding protrusion to slide upward along the second guide step surface, causing the lower guide member to rise. This structure is simple and allows the rotation of the rotating member to smoothly raise or lower the lower guide member.

[0010] Preferably, a second locking position is provided at the lower end of the second guide step surface. The second locking position is a groove structure with the slot facing downwards. When the rotating component rotates forward, it drives the second sliding protrusion to slide downwards along the corresponding second guide step surface into the second locking position, which is used to lock the lower guide component at its lowest height. When the rotating component rotates in reverse, the lower elastic rebound drives the second sliding protrusion to move upwards and disengage from the second locking position, unlocking the lower guide component. With this structure and the second locking position, it is beneficial to keep the position of the pen tip stationary during writing, preventing the pen tip from transmitting the force from the lower guide component to the rotating component due to the writing force, thus preventing the rotating component from reversing, and preventing the pen tip from retracting into the pen barrel during writing.

[0011] Preferably, a second limiting stop is provided at the lower end of any second guide step surface on the rotating component. When there is only one second guide step surface, the two side walls of the second limiting stop are the lower and upper end stops of the second guide step surface, respectively. When there are two or more second guide step surfaces, any one second limiting stop is located between two adjacent second guide step surfaces, with one side wall of the second limiting stop serving as the lower end stop of one of the second guide step surfaces and the other side wall serving as the upper end stop of another second guide step surface. The side walls of the second limiting stop serve as stops to limit the second sliding protrusion. This structure helps to prevent the second sliding protrusion from disengaging from the second guide step surface due to excessive rotation of the rotating component.

[0012] Preferably, the operating part is a pusher located in the middle of the rotating component. The rotating component has a insertion hole, one end of the pusher is inserted into the insertion hole, and the other end extends out of the operating window. The pusher can slide left and right along the operating window to drive the rotating component to rotate forward or backward. This structure, with the pusher extending out of the operating window, facilitates the operation of the rotating component and also limits its axial movement; the insertion of the pusher into the rotating component facilitates assembly.

[0013] Preferably, a locking protrusion is provided on the side wall of the operating window. The pushing member slides along the operating window toward the locking protrusion, causing the rotating member to rotate clockwise, raising the upper guide member and lowering the lower guide member. When the decorative member and the pen refill extend simultaneously from the top and bottom of the pen barrel, respectively, the pushing member can slide to the locking protrusion. The locking protrusion is used to abut and limit the pushing member to lock the rotating member. With this structure, the locking protrusion abuts and limits the pushing member to lock the rotating member, which helps to keep the pen tip in a fixed position during writing, prevents the pen tip from transferring the force from the lower guide member to the rotating member due to the writing force, and prevents the pen tip from retracting into the pen barrel during writing. It also prevents the decorative member from accidentally retracting into the pen barrel.

[0014] Preferably, the pen barrel includes an upper pen barrel and a lower pen barrel connected by threads, with an upper guide member located inside the upper pen barrel. The top of the upper pen barrel has an upper opening for assembling the upper guide member and decorative parts. An axially extending first limiting groove is provided on the inner side wall of the upper pen barrel, communicating with the upper opening. A first limiting protrusion, which mates with the first limiting groove, is provided on the outer side wall of the upper guide member, allowing it to slide up and down along the first limiting groove. A rear seal is provided on the outer side of the upper opening, used to axially limit the movement of the upper guide member. This structure facilitates the assembly of the upper guide member. The mate between the first limiting protrusion and the first limiting groove facilitates circumferential limiting of the upper guide member, preventing interference with the rotation of the rotating parts. The ability of the first limiting protrusion to slide up and down along the first limiting groove facilitates the vertical movement of the upper guide member.

[0015] Preferably, the rotating component is located inside the upper pen barrel, and the bottom end of the upper pen barrel has a lower opening for assembling the rotating component. A first limiting protrusion is provided on the inner side wall of the upper pen barrel, and an upward-facing annular limiting step surface is provided on the outer side wall of the rotating component. The annular limiting step surface fits below the first limiting protrusion. A second limiting protrusion is provided on the inner side wall of the upper pen barrel. The inner side wall of the second limiting protrusion is an arc surface. An annular limiting block is provided inside the upper pen barrel. The inner side wall of the second limiting protrusion can be interference-fitted with the outer side wall of the limiting block. The second limiting protrusion is below the limiting block and is used to axially limit the limiting block. The rotating component is located above the limiting block, and the limiting block is used to support the rotating component. The first limiting protrusion and the limiting block together axially limit the rotating component. This structure facilitates the assembly of rotating parts. The inner wall of the second limiting protrusion is an arc surface, and the inner wall of the second limiting protrusion can be interference-fitted with the outer wall of the limiting block. This makes it convenient for the limiting block to be assembled from the lower opening to the upper part of the second limiting protrusion, thus facilitating axial limiting of the rotating parts in both the vertical and horizontal directions.

[0016] Preferably, the lower guide member is located inside the upper pen barrel. The lower opening is used to assemble the lower guide member. An axially extending third limiting groove is provided on the inner side wall of the upper pen barrel, communicating with the lower opening. A third limiting protrusion is provided on the outer side wall of the lower guide member, engaging with the third limiting groove. The third limiting protrusion can slide up and down along the third limiting groove. This structure facilitates the assembly of the lower guide member. The engagement between the third limiting protrusion and the third limiting groove facilitates circumferential positioning of the lower guide member, preventing it from interfering with the rotation of the rotating component. The ability of the third limiting protrusion to slide up and down along the third limiting groove facilitates the vertical movement of the lower guide member.

[0017] Preferably, the third limiting groove passes through the inner wall of the second limiting protrusion, and a second limiting protrusion that mates with the third limiting groove is provided on the outer wall of the limiting block. This structure facilitates circumferential limiting of the limiting block and prevents the limiting block from interfering with the rotation of the rotating component.

[0018] Preferably, the lower part of the upper guide member is sleeved on the upper part of the rotating member, or the upper part of the rotating member is sleeved on the lower part of the upper guide member. At least one spiral-shaped first guide groove is provided on the side wall connecting the rotating member and the upper guide member, and a first sliding protrusion corresponding to the first guide groove is provided on the side wall connecting the upper guide member and the rotating member. The first sliding protrusion is slidably connected within the corresponding first guide groove. When the rotating member rotates clockwise, the lower groove wall of the first guide groove drives the first sliding protrusion to slide upwards along the first guide groove, causing the upper guide member to rise. When the rotating member rotates counterclockwise, the upper groove wall of the first guide groove drives the first sliding protrusion to slide downwards along the first guide groove, causing the upper guide member to descend. This structure is simple, allows the rotation of the rotating member to smoothly raise or lower the upper guide member, and eliminates the need for an elastic element.

[0019] Preferably, the upper part of the lower guide member is sleeved on the lower part of the rotating member, or the lower part of the rotating member is sleeved on the upper part of the lower guide member. At least one spiral-shaped second guide groove is provided on the side wall connecting the rotating member and the lower guide member, and a second sliding protrusion corresponding to the second guide groove is provided on the side wall connecting the lower guide member and the rotating member. The second sliding protrusion is slidably connected within the corresponding second guide groove. When the rotating member rotates clockwise, the upper groove wall of the second guide groove drives the second sliding protrusion to slide downwards along the second guide groove, causing the lower guide member to descend. When the rotating member rotates counterclockwise, the lower groove wall of the second guide groove drives the second sliding protrusion to slide upwards along the second guide groove, causing the lower guide member to rise. This structure is simple, allows the rotation of the rotating member to smoothly raise or lower the lower guide member, and eliminates the need for an elastic element. Attached Figure Description

[0031] Example 1:

[0032] like Figure 1 and Figure 2 As shown, the rotating lead-out pen of this utility model includes a pen barrel, which includes an upper pen barrel 5 and a lower pen barrel 11 connected by threads. An upper guide member 4, a rotating member 6, and a lower guide member 9 are arranged sequentially inside the upper pen barrel 5. An operation window 5-4 is provided on the side wall of the upper pen barrel 5. A push member 7 is provided in the middle of the rotating member 6. An insertion hole 6-7 is provided on the rotating member 6. One end of the push member 7 is inserted into the insertion hole 6-7, and the other end extends out of the operation window 5-4. The push member 7 can slide left and right along the operation window 5-4 to drive the rotating member 6 to rotate forward or backward inside the upper pen barrel 5. A decorative member 1 is provided at the upper end of the upper guide member 4, and a pen lead 10 is provided at the lower end of the lower guide member 9.

[0033] like Figure 3 As shown, the top of the upper pen barrel 5 has an upper opening for assembling the upper guide 4 and the decorative part 1. The inner sidewall of the upper pen barrel 5 has an axially extending first limiting groove 5-1, which communicates with the upper opening. Figure 6 As shown, the outer side wall of the upper guide member 4 is provided with a first limiting protrusion 4-1 that engages with the first limiting groove 5-1. The upper guide member 4 is circumferentially limited by the upper pen barrel 5, and the upper guide member 4 can slide up and down along the first limiting groove 5-1. An annular rear seal 2 is provided on the outer side of the upper opening. The rear seal 2 is used to axially limit the upper guide member 4, and the decorative member 1 can extend and retract in the inner ring of the rear seal 2.

[0034] like Figure 3 As shown, the bottom end of the upper pen barrel 5 has a lower opening for assembling the rotating component 6 and the lower guide component 9; a first limiting protrusion ring is provided on the inner side wall of the upper pen barrel 5. Figure 4 As shown, the outer wall of the rotating component 6 is provided with an upward-facing annular limiting step surface, which fits below the first limiting protrusion ring. The inner wall of the upper pen barrel 5 is provided with a second limiting protrusion ring 5-2, the inner wall of which is an arc surface. An annular limiting block 8 is provided inside the upper pen barrel 5. The inner wall of the second limiting protrusion ring 5-2 can be interference-fitted with the outer wall of the limiting block 8. The limiting block 8 can enter the upper pen barrel 5 through the lower opening and be pushed upwards above the second limiting protrusion ring 5-2. The second limiting protrusion ring 5-2, located below the limiting block 8, is used to axially limit the limiting block 8. The rotating component 6 is located above the limiting block 8, and the limiting block 8 is used to support the rotating component 6. The first limiting protrusion ring and the limiting block 8 together axially limit the rotating component 6.

[0035] A third limiting groove 5-3 extending axially is provided on the inner side wall of the upper pen barrel 5. The third limiting groove 5-3 communicates with the lower opening, such as... Figure 7 As shown, the outer wall of the lower guide member 9 is provided with a third limiting protrusion 9-1 that mates with the third limiting groove 5-3. The lower guide member 9 is circumferentially limited by the upper pen barrel 5, and the lower guide member 9 can slide up and down along the third limiting groove 5-3. The third limiting groove 5-3 passes through the inner wall of the second limiting protrusion ring 5-2. The outer wall of the limiting block 8 is provided with a second limiting protrusion 8-1 that mates with the third limiting groove 5-3. The limiting block 8 is also circumferentially limited by the upper pen barrel 5.

[0036] like Figure 4As shown, two first guide step surfaces 6-1 are provided on the upper outer side wall of the rotating component 6. The two first guide step surfaces 6-1 are spirally arranged symmetrically around the outer side wall of the rotating component 6. A first limiting stop 6-3 is provided at the upper end of any one of the first guide step surfaces 6-1 on the rotating component 6. Each first limiting stop 6-3 is located between two first guide step surfaces 6-1. One side wall of the first limiting stop 6-3 is the upper end stop wall of one of the adjacent first guide step surfaces 6-1, and the other side wall of the first limiting stop 6-3 is the lower end stop wall of the other adjacent first guide step surface 6-1. A first locking position 6-2 is provided between the upper end of the first guide step surface 6-1 and the first limiting stop 6-3. The first locking position 6-2 is a groove structure with the slot facing upward.

[0037] like Figure 6 As shown, the lower part of the upper guide member 4 is provided with an inner cavity, which is used to fit onto the upper part of the rotating member 6. A first sliding protrusion 4-2 corresponding to the first guide step surface 6-1 is provided on the cavity wall of the inner cavity. The first sliding protrusion 4-2 is slidably connected to the corresponding first guide step surface 6-1. Rotation of the rotating member 6 causes the first sliding protrusion 4-2 to slide upwards or downwards along the first guide step surface 6-1, thereby raising or lowering the upper guide member 4. The first sliding protrusion 4-2 slides upwards along the corresponding first guide step surface 6-1 into the first locking position 6-2, locking the upper guide member 4 at its highest height. The side wall of the first limiting stop 6-3 acts as a stop to limit the first sliding protrusion 4-2 to the corresponding first guide step surface 6-1.

[0038] An upper spring 3 is provided between the upper guide 4 and the rear seal 2, with the lower end of the upper spring 3 connected to the upper guide 4. When the rotating part 6 rotates forward, it drives the first sliding protrusion 4-2 to slide upward along the first guide step surface 6-1, causing the upper guide 4 to rise and the upper spring 3 to be compressed until the first sliding protrusion 4-2 enters the first locking position 6-2, locking the upper guide 4. At this time, the decorative part 1 extends out from the inner ring of the rear seal 2. When the rotating part 6 rotates in the reverse direction, the upper spring 3 rebounds and drives the first sliding protrusion 4-2 to move downward and disengage from the first locking position 6-2, unlocking the upper guide 4. The upper guide 4 then descends, and the decorative part 1 retracts from the inner ring of the rear seal 2 into the upper pen barrel 5.

[0039] like Figure 5As shown, the lower part of the rotating member 6 is provided with an inner cavity, which is used to fit onto the upper part of the lower guide member 9. Two second guide step surfaces 6-4 are provided on the cavity wall of the rotating member 6. The two second guide step surfaces 6-4 are spirally arranged symmetrically around the cavity wall of the rotating member 6. A second limiting stop 6-6 is provided at the lower end of any second guide step surface 6-4 on the rotating member 6. Each second limiting stop 6-6 is located between two adjacent second guide step surfaces 6-4. One side wall of the second limiting stop 6-6 is the lower end stop wall of one of the adjacent second guide step surfaces 6-4, and the other side wall of the second limiting stop 6-6 is the upper end stop wall of the other adjacent second guide step surface 6-4. A second locking position 6-5 is provided between the lower end of the second guide step surface 6-4 and the second limiting stop 6-6. The second locking position 6-5 is a groove structure with the slot facing downward.

[0040] like Figure 7 As shown, a second sliding protrusion 9-2 corresponding to the second guide step surface 6-4 is provided on the outer wall of the upper part of the lower guide member 9. The second sliding protrusion 9-2 is slidably connected to the corresponding second guide step surface 6-4. Rotation of the rotating member 6 can cause the second sliding protrusion 9-2 to slide upward or downward along the second guide step surface 6-4, thereby causing the lower guide member 9 to rise or fall. The second sliding protrusion 9-2 slides downward along the corresponding second guide step surface 6-4 into the second locking position 6-5, locking the lower guide member 9 at the lowest height. The side wall of the second limiting stop 6-6 acts as a stop to limit the second sliding protrusion 9-2 on the corresponding second guide step surface 6-4.

[0041] A lower spring 12 is provided between the pen refill 10 and the lower pen barrel 11, with the upper end of the lower spring 12 connected to the pen refill 10. When the rotating component 6 rotates forward, it drives the second sliding protrusion 9-2 to slide downward along the second guide step surface 6-4, causing the lower guide component 9 to descend and the lower spring 12 to be compressed until the second sliding protrusion 9-2 enters the second locking position 6-5, locking the lower guide component 9. At this time, the pen tip 10-1 of the pen refill 10 extends from the bottom end of the lower pen barrel 11. When the rotating component 6 rotates in reverse, the lower spring 12 rebounds, driving the second sliding protrusion 9-2 to move upward and disengage from the first locking position 6-2, unlocking the lower guide component 9. The lower guide component 9 then moves upward along the second guide step surface 6-4, causing the lower guide component 9 to rise and the pen tip 10-1 of the pen refill 10 to retract into the lower pen barrel 11.

[0042] As described above, the rotation of the rotating member 6 causes the upper guide member 4 and the lower guide member 9 to slide in opposite directions along the length of the pen barrel. The upper guide member 4 and the lower guide member 9 can respectively drive the decorative member 1 and the pen tip 10 to move in opposite directions. When the rotating member 6 rotates forward, it drives the upper guide member 4 and the lower guide member 9 to rise and fall respectively until the upper guide member 4 and the lower guide member 9 are locked at the same time. At this time, the pen tip 10-1 of the decorative member 1 and the pen tip 10 of the pen tip 10 extend from the top of the upper pen barrel 5 and the bottom of the lower pen barrel 11 at the same time. When the rotating member 6 rotates in reverse, the upper spring 3 drives the upper guide member 4 to fall and the lower spring 12 drives the lower guide member 9 to rise until the decorative member 1 retracts into the upper pen barrel 5. At the same time, the pen tip 10-1 of the pen tip 10 retracts into the lower pen barrel 11.

[0043] Example 2:

[0044] The difference between the rotating lead-ejecting pen in this embodiment and that in embodiment 1 is that the upper part of the rotating member 6 is provided with an inner cavity that fits onto the lower part of the upper guide member 4, instead of the lower part of the upper guide member 4 fitting onto the upper part of the rotating member 6. Correspondingly, the first guide step surface 6-1 is provided on the inner cavity wall of the upper part of the rotating member 6, and the first sliding protrusion 4-2 is provided on the outer wall of the lower part of the upper guide member 4. The upper part of the lower guide member 9 is provided with an inner cavity that fits onto the lower part of the rotating member 6, instead of the lower part of the rotating member 6 fitting onto the top of the lower guide member 9. Correspondingly, the second guide step surface 6-4 is provided on the outer wall of the lower part of the rotating member 6, and the second sliding protrusion 9-2 is provided on the inner cavity wall of the upper part of the lower guide member 9.

[0045] Example 3:

[0046] The difference between the rotating pen in this embodiment and that in Embodiment 1 is that a locking protrusion is provided on the side wall of the operating window 5-4. The pushing member 7 slides along the operating window 5-4 toward the locking protrusion, causing the rotating member 6 to rotate clockwise, causing the upper guide member 4 to rise and the lower guide member 9 to fall. When the decorative member 1 and the pen lead 10 extend simultaneously from the top and bottom of the pen barrel, the pushing member 7 can slide to the locking protrusion. The locking protrusion is used to abut and limit the pushing member 7 to lock the rotating member 6. The locking protrusion on the side wall of the operating window 5-4 to lock the pushing member 7 replaces the first locking position 6-2 at the upper end of the first guide step surface 6-1 to lock the upper guide member 4, and the second locking position 6-5 at the lower end of the second guide step surface 6-4 to lock the lower guide member 9.

[0047] Example 4:

[0048] The difference between the rotating pen in this embodiment and that in embodiment 1 is that the rotating component 6 can be provided with an operating hole opposite to the operating window 5-4. The rotating component 6 can be rotated left and right within the pen barrel by inserting a finger into the operating hole and moving it left and right within the operating window 5-4, thereby replacing the use of a pusher 7 on the rotating component 6.

[0049] Example 5:

[0050] The difference between the rotating lead-ejecting pen in this embodiment and that in Embodiment 1 is that a spiral-shaped first guide groove is provided on the side wall where the rotating member 6 connects to the upper guide member 4, and a first sliding protrusion corresponding to the first guide groove is provided on the side wall where the upper guide member 4 connects to the rotating member 6. The first sliding protrusion is slidably connected in the corresponding first guide groove. When the rotating member 6 rotates clockwise, the lower side wall of the first guide groove can drive the first sliding protrusion to slide upward along the first guide groove, and the upper guide member 4 rises. When the rotating member 6 rotates counterclockwise, the upper side wall of the first guide groove can drive the first sliding protrusion to slide downward along the first guide groove, and the upper guide member 4 descends.

[0051] A spiral-shaped second guide groove is provided on the side wall where the rotating member 6 connects to the lower guide member 9. A second sliding protrusion corresponding to the second guide groove is provided on the side wall where the lower guide member 9 connects to the rotating member 6. The second sliding protrusion is slidably connected in the corresponding second guide groove. When the rotating member 6 rotates clockwise, the upper groove wall of the second guide groove can drive the second sliding protrusion to slide downward along the second guide groove, and the lower guide member 9 descends. When the rotating member 6 rotates counterclockwise, the lower groove wall of the second guide groove can drive the second sliding protrusion to slide upward along the second guide groove, and the lower guide member 9 rises.

[0052] This embodiment eliminates the need for the upper spring 3 used to drive the upper guide 4 downward and the lower spring 12 used to drive the lower guide 9 upward.

[0053] In other embodiments, the upper part of the rotating member 6 can be threadedly connected to the lower part of the upper guide member 4, and the lower part of the rotating member 6 can also be threadedly connected to the upper part of the lower guide member 9. The threads of the upper and lower parts of the rotating member 6 rotate in opposite directions, so that the rotating member 6 can simultaneously drive the upper guide member 4 to rise and the lower guide member 9 to fall when rotating in the forward direction, and the rotating member 6 can simultaneously drive the upper guide member 4 to fall and the lower guide member 9 to rise when rotating in the reverse direction.

[0054] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope shall be covered within the protection scope of the claims of this utility model.
