Description

Technical Field

[0001] This invention relates to the field of correction tape technology, and more specifically to a retractable correction tape. Background Technology

[0002] Correction tape is a common school and office supply. It generally consists of a housing, a correction head, and a core assembly. The core assembly has a membrane tape attached to cover the area to be corrected. The membrane tape wraps around the correction head and covers the area. To prevent the correction head and part of the membrane tape from being exposed and getting dirty, a protective cap is usually fitted onto the correction head. However, correction tape requires repeated opening and closing operations, which is cumbersome and the protective cap is easily lost. Therefore, a technical solution has been proposed: correction tape with a retractable correction head, such as... The invention patent with patent number CN104773016B discloses a soft membrane push nozzle correction tape, including a housing, a correction tape body and a nozzle disposed within the housing; the correction tape body and the nozzle are jointly disposed on a sliding member, the housing is provided with a nozzle opening for the nozzle to extend and retract, and the housing is also provided with an arc-shaped track that extends around the edge of the nozzle opening; a soft membrane is movably mounted within the arc-shaped track, and the soft membrane has two connection points on both sides of its center, one connection point being connected to the sliding member, and the other connection point being connected to an operating part that extends out of the housing for manual operation. In this technical solution, the correction tape body and the nozzle are mounted together on a sliding member. The sliding member moves the nozzle and correction tape body to extend out of the housing or retract into the housing to protect the nozzle (i.e., the correction head). However, this structure requires space to be reserved inside the housing for the extension and retraction of the correction tape body (i.e., the core assembly), resulting in a larger housing volume and affecting the user experience. However, if only the nozzle (i.e., the correction head) is extended and retracted, the synchronous extension and retraction of the film tape must be considered. Otherwise, the film tape wrapped around the nozzle is easily contaminated or broken due to being exposed, affecting normal use. Therefore, there is a need for a telescopic correction tape that does not increase the size of the correction tape and allows the film tape to be extended and retracted synchronously. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a telescopic correction tape, which controls only the extension and retraction of the correction head through a drive component, and by setting a swingable guide belt component, the film tape exposed outside the housing can be extended and retracted synchronously when the correction head extends and retracts, which has the advantages of reducing the volume of the telescopic correction tape and not affecting the use of the film tape.

[0004] This invention provides a telescopic correction tape, comprising a housing, a correction head and a core assembly mounted on the housing, and an opening for the correction head to extend and retract. The core assembly includes a film roll, a core coil, and a take-up coil. The film roll passes over the correction head and is wound around the take-up coil. A drive assembly is slidably mounted on the housing and connected to the correction head. The drive assembly drives the correction head to extend and retract by sliding. A guide member is rotatably connected to the core assembly. The film roll passes over the correction head after passing through the guide member. One side of the guide member is connected to the drive assembly via a transmission assembly. When the drive assembly drives the correction head to extend, part of the film roll is pushed out by the correction head, and the guide member rotates closer to the drive assembly due to the tightening force of the film roll. When the drive assembly drives the correction head to retract, the drive assembly acts on the guide member via the transmission assembly, causing the guide member to rotate away from the drive assembly and retract the film roll exposed outside the housing.

[0005] In this technical solution, a sliding drive assembly is installed in the housing, and the drive assembly is connected to the correction head. The user applies force to the drive assembly, which in turn drives the correction head, causing it to extend and retract relative to the housing through an opening. Since the drive assembly only moves the correction head, and the core assembly remains stationary within the housing, there is no need to reserve space for the core assembly to slide within the housing. Therefore, the housing volume does not need to be large, allowing for a smaller telescopic correction tape. Considering that when only the correction head retracts, a portion of the film tape wrapped around it remains exposed, this solution prevents damage to this portion. The core assembly is rotatably connected to a guide belt member. The film tape first passes through the guide belt member and then around the correction head. The guide belt member rotates within the housing, changing the path length of the film tape to the correction head. When the user applies force to the drive assembly, causing the correction head to extend through the opening... The film strip on the correction head is pushed out by the correction head. At this time, the film strip has an inward tightening force. The guide belt is rotated closer to the drive component due to the tightening force of the film strip, which shortens the path of the film strip to the correction head. This ensures that the length of the film strip is sufficient for the correction head to push out, without having to release more film strip from the core assembly. When the user applies force to the drive assembly to make the correction head retract through the opening, the drive assembly drives the correction head to slide backward. One side of the guide belt is connected to the drive assembly via the transmission assembly. The guide belt is rotated away from the drive assembly due to the backward sliding force of the drive assembly, which lengthens the path of the film strip to the correction head. This allows the part of the film strip exposed outside the housing to be retracted due to the extended path, without having to retract excess film strip through the core assembly. This technical solution allows the film strip to be retracted and extended synchronously with the extension and retraction of the correction head through the guide belt, resulting in a simple structure and a good user experience.

[0006] As an improvement, the transmission assembly includes a protrusion disposed on the guide belt and a drive wall disposed on the drive assembly, the protrusion and the drive wall abutting against each other.

[0007] In this technical solution, the transmission component is formed by the cooperation of a protrusion and a drive wall. The protrusion abuts against the drive wall. When the drive component is subjected to force, it drives the correction head to slide backward. The drive component, through the transmission cooperation between the drive wall and the protrusion, causes the guide belt to rotate away from the drive component, resulting in higher transmission efficiency. On the other hand, the protrusion is set on the guide belt and the drive wall is set on the drive component, resulting in a compact structure that does not increase the size of the correction belt and provides a better user experience.

[0008] Furthermore, the drive assembly is provided with a relief portion adapted to the protrusion. The relief portion is located on the rear side of the drive wall. When the drive assembly drives the correction head to extend, the drive assembly slides forward relative to the protrusion, causing the protrusion to enter the relief portion.

[0009] In this technical solution, by setting a relief part on the drive component that can accommodate the protrusion, when the user applies force to the drive component to drive the correction head to slide forward, the drive component slides forward relative to the guide belt. Under the tightening force of the film belt, the guide belt rotates close to the drive component. At this time, the protrusion of the guide belt can enter the relief part, so that the overall structure is more compact and saves space.

[0010] As an improvement, this solution can also provide another specific structure of the transmission component, which includes a protrusion disposed on the drive component and a drive wall disposed on the guide belt, wherein the protrusion and the drive wall abut against each other.

[0011] In this technical solution, the protrusion is set on the drive assembly and the drive wall is set on the guide belt. The protrusion abuts against the drive wall. When the drive assembly is subjected to force, it drives the correction head to slide backward. The drive assembly makes the guide belt rotate away from the drive assembly through the transmission cooperation between the protrusion and the drive wall. The principle is the same as the specific structure of the previous transmission assembly, and the transmission efficiency is high.

[0012] Furthermore, the guide belt is provided with a relief portion that is adapted to the protrusion. The relief portion is located on the rear side of the drive wall. When the drive assembly drives the correction head to extend, the drive assembly slides forward relative to the protrusion so that the protrusion enters the relief portion.

[0013] In this technical solution, the protrusion is provided on the drive assembly, and the clearance part is provided on the guide belt. When the user applies force to the drive assembly to drive the correction head to slide forward, the drive assembly slides forward relative to the guide belt. Under the tightening force of the film belt, the guide belt rotates close to the drive assembly. At this time, the protrusion of the drive assembly can enter the clearance part to make the overall structure more compact and save space.

[0014] As an improvement, the protrusion is semi-circular or triangular. In this technical solution, the protrusion is set to be semi-circular or triangular, which increases the angle at which the guide belt can be rotated and opened, thereby allowing the guide belt to be reduced in size and saving installation space.

[0015] As an improvement, this solution can provide at least three specific structures for the clearance portion:

[0016] Firstly, the clearance portion has a hollow structure. When the drive assembly and the guide belt rotate relative to each other and approach each other, the clearance portion accommodates the protrusion through the hollow structure. In this technical solution, by setting the clearance portion as a hollow structure, that is, setting the part of the drive assembly located on the rear side of the drive wall as a cavity, and accommodating the protrusion through this cavity, the drive wall can fit against the side wall of the guide belt when the drive assembly and the guide belt rotate relative to each other and approach each other, so that the film strip on the guide belt can be released, the structure inside the correction belt is more compact, and the hollow structure saves materials and can reduce the production cost of the drive assembly.

[0017] Secondly, the clearance portion has an inclined structure, which is engaged with the drive wall. When the drive assembly and the guide belt rotate relative to each other and approach each other, the protrusion enters the clearance portion through the guiding effect of the inclined structure. In this technical solution, the clearance portion is set as an inclined structure engaged with the drive wall. The inclined structure has a guiding effect, which makes the protrusion enter the clearance portion more smoothly, avoids problems such as jamming, and is less labor-intensive and more reliable.

[0018] Thirdly, the relief portion is a hollow structure, and the sidewall of the hollow structure that mates with the protrusion is an inclined surface; this technical solution combines the above two specific structures of the relief portion, so that the setting of the relief portion can not only save materials and reduce costs, but also avoid problems such as jamming, and the use effect is better.

[0019] As an improvement, the guide belt has a triangular structure, with one end rotatably connected to the belt core assembly. In this technical solution, the guide belt is triangular in structure, with the end rotatably connected to the belt core assembly serving as the fulcrum, and the end furthest from the fulcrum serving as the pivot point. For the membrane belt to pass around the correction head, it must first pass through the end furthest from the fulcrum. This end furthest from the fulcrum changes its position by rotating around the fulcrum, thus altering the path of the membrane belt. This allows the membrane belt to expand and contract synchronously with the extension and retraction of the correction head. Furthermore, the ends of the housing with openings are mostly trapezoidal, ensuring that the correction head's extension through the opening is not affected by the housing. The triangular guide belt is more compatible with the ends of the housing with openings and does not affect the dimensions of the housing.

[0020] As an improvement, the drive assembly includes a drive seat and a push button. The drive seat is connected to the correction head and has a linkage part. The housing has a sliding groove that slides with the linkage part. The linkage part passes through the sliding groove and is connected to the push button. When the push button is subjected to force, it drives the drive seat to slide through the linkage part.

[0021] In this technical solution, the drive seat is connected to the push button via a linkage part. By setting the linkage part to slide in a sliding engagement with the slide groove, when the user applies force to the push button, the push button acts on the linkage part, causing the linkage part to slide within the slide groove, thereby driving the drive seat to slide on the housing. By setting the drive seat to connect with the correction head, the sliding of the drive seat drives the correction head to extend and retract, resulting in a good sliding engagement.

[0022] Furthermore, the slide groove is provided with a locking part, the linkage part is installed with an elastic element, and the elastic element is formed with a positioning part adapted to the locking part. The positioning part engages with the locking part to make the drive seat slide and lock. The push button is provided with an unlocking part adapted to the positioning part. When the push button is subjected to force, it acts on the positioning part through the unlocking part. When the positioning part is subjected to force, it undergoes elastic deformation and disengages from the locking part, thus making the drive seat slide and unlock.

[0023] In this technical solution, a locking part is provided on the slide groove and a positioning part is provided on the elastic element. When the linkage part slides in the slide groove, the drive seat is locked by engaging with the positioning part and the locking part. An unlocking part is provided on the push button. When the user applies force to the push button, the unlocking part is subjected to force, causing the positioning part to elastically deform and disengage from the locking part, thereby unlocking the drive seat. The sliding locking and unlocking eliminate the need for the user to constantly apply force to the push button to keep the drive seat and correction head in an extended or retracted state when using correction tape, making it more labor-saving and convenient to use, and providing a better user experience.

[0024] Furthermore, the push button and the linkage part slide together, the push button is provided with a limit post, and the linkage part is provided with a limit part adapted to the limit post. When the push button slides on the linkage part, the end of the limit post and the limit part abut against each other to drive the drive seat to slide.

[0025] In this technical solution, a push button and a linkage part are slidably engaged. The push button can slide on the linkage part, and the force applied to the push button on the linkage part causes the unlocking part to act on the positioning part, thereby enabling the positioning part to disengage from the locking part and achieve sliding unlocking. By setting a limiting post on the push button and a limiting part on the linkage part, the push button, when subjected to force and sliding, first disengages the positioning part from the locking part to achieve sliding unlocking. The push button continues to slide until the ends of the limiting post and the limiting part abut against each other, allowing the push button to drive the drive seat to slide, thereby enabling the correction head to extend and retract. The structure is simple and the use is labor-saving.

[0026] As an improvement, this solution can also provide another specific structure of the drive component, which includes a drive seat and a push button. The drive seat is connected to the correction head, and a linkage part is provided on the drive seat. The housing is provided with a sliding groove that slides with the linkage part. The linkage part passes through the sliding groove and is connected to the push button. When the push button is subjected to force, it drives the drive seat to slide through the linkage part.

[0027] The slide groove is provided with a locking part, and the linkage part is provided with a positioning part adapted to the locking part. The positioning part engages with the locking part to achieve sliding locking, and the positioning part disengages from the locking part to achieve sliding unlocking. The locking part and / or the positioning part are elastic structures.

[0028] In this technical solution, by setting an elastic locking part and / or an elastic positioning part, the push button is forced to drive the drive seat to slide. The positioning part engages with the locking part through sliding to lock the drive seat. When the push button is forced again, it drives the drive seat to slide. The positioning part and the locking part are forced to disengage through elastic deformation to unlock the drive seat. The structure is simpler and easier to manufacture and install.

[0029] As an improvement, this solution can also provide another specific structure of the drive component, which includes a drive base and a push button disposed on the drive base. The drive base is connected to the correction head, and the housing is provided with a slide groove that slides with the push button. The push button extends through the slide groove, and the push button is forced to drive the drive base to slide.

[0030] In this technical solution, the structure is simpler by setting the drive seat to slide on the housing via a push button. When the user applies force to the push button, the push button slides in the groove under force, and the push button drives the drive seat to slide on the housing. By setting the drive seat to connect with the correction head, the sliding of the drive seat drives the correction head to extend and retract. The sliding fit is better and the use is more labor-saving.

[0031] Furthermore, both ends of the slide are provided with limiting holes adapted to the push button. The limiting holes are C-shaped. The push button slides into the limiting hole under force to achieve sliding lock, and the push button slides out of the limiting hole under force to achieve sliding unlock.

[0032] In this technical solution, by setting a limiting hole on the slide, the push button slides into the limiting hole and locks with the limiting hole to achieve sliding lock. The user can slide the push button out of the limiting hole to achieve sliding unlock by applying a large force. The structure is simple.

[0033] Furthermore, the drive seat and the push button are integrally molded, and the push button is cylindrical.

[0034] As an improvement, one end of the drive seat is provided with a mounting part, one end of the correction head is fixed to the mounting part, and one side of the mounting part abuts against one side of the guide belt.

[0035] In this technical solution, by setting a mounting part adapted to the correction head at one end of the drive seat, the correction head is fixed by the mounting part, making the structure of the drive seat sliding to drive the correction head to extend and retract more reliable, and the structure of fixing the correction head is simpler. The drive seat is set to abut against the guide belt through the mounting part, so that when the drive seat slides, the guide belt is controlled to rotate in a direction away from the mounting part through the mounting part. The cooperation between the mounting part and the guide belt is reliable, and the size of the mounting part is small, so it will not affect the rotation of the guide belt, and the rotation efficiency is higher.

[0051] Example 1

[0052] like Figures 1 to 8 As shown, this application discloses a telescopic correction tape, including a housing 1. The housing 1 is equipped with a correction head 2 and a core assembly 3. The housing 1 is provided with an opening 11 for the correction head 2 to extend and retract. The core assembly 3 includes a film roll 31, a core coil 32, and a take-up coil 35. The film roll 31 passes around the correction head 2 and is wound on the take-up coil 35. A drive assembly 4 is slidably installed on the housing 1. The drive assembly 4 is connected to the correction head 2. The drive assembly 4 drives the correction head 2 to extend and retract by sliding. By providing a drive assembly 4 that can slide relative to the housing 1 and is connected to the correction head 2, the user applies force to the drive assembly 4, and the drive assembly 4 drives the correction head 2. The correction head 2 extends and retracts relative to the housing 1 through the opening 11. The drive assembly 4 is set to only drive the correction head 2 to extend and retract, and the core assembly 3 is installed in the housing 1 without moving. This eliminates the need to reserve space for the core assembly 3 to slide in the housing 1. Therefore, the volume of the housing 1 does not need to be large, and the size of the telescopic correction tape can be reduced.

[0053] like Figure 3 and Figure 4 As shown, the core assembly 3 is rotatably connected to a guide belt member 33. The membrane belt first passes through the guide belt member 33 and then around the correction head 2. One side of the guide belt member 33 is connected to the drive assembly 4 via a transmission assembly. The guide belt member 33 can change the length of the path of the membrane belt to the correction head 2 by rotating within the housing 1. When the user applies force to the drive assembly 4, causing the correction head 2 to extend through the opening 11, the membrane belt on the correction head 2 is pushed out by the correction head 2. At this time, the membrane belt has an inward tightening force. The guide belt member 33 is subjected to the tightening force of the membrane belt and rotates closer to the drive assembly 4, which shortens the path of the membrane belt to the correction head 2, so that the length of the membrane belt is sufficient to be pushed out by the correction head 2 without having to exit from the core assembly 3. More film strip is released. When the user applies force to the drive component 4 to make the correction head 2 retract through the opening 11, the drive component 4 drives the correction head 2 to slide backward. One side of the guide belt 33 is connected to the drive component 4 via the transmission component. The guide belt 33 is rotated away from the drive component 4 by the backward sliding force of the drive component 4, which extends the path of the film strip to the correction head 2. Thus, the part of the film strip exposed outside the housing 1 can be retracted due to the extended path. There is no need to retract the excess film strip through the belt core component 3. This technical solution can make the film strip be retracted and extended synchronously with the extension and retraction of the correction head 2 through the guide belt 33. The structure is simple and the user experience is good.

[0054] More specifically, in this embodiment, the retraction of the correction head 2 is 10mm, and the rotation angle of the guide belt 33 is 47°.

[0055] More specifically, such as Figure 3 and Figure 4 As shown, the guide belt 33 has a triangular structure. One end of the guide belt 33 is rotatably connected to the belt core assembly 3. The end of the guide belt 33 that is rotatably connected to the belt core assembly 3 is the fulcrum, while the end farthest from the fulcrum is the pivot point. The membrane belt needs to pass through the end farthest from the fulcrum before it can go around the correction head 2. This end farthest from the fulcrum changes its position by rotating around the fulcrum, thereby changing the path of the membrane belt. This allows the membrane belt to expand and contract synchronously with the extension and retraction of the correction head 2. On the other hand, the ends of the housing 1 with openings 11 are mostly trapezoidal, so that the correction head 2 can be used without being affected by the housing 1 after it extends through the openings 11. The triangular guide belt 33 is more compatible with the ends of the housing 1 with openings 11 and will not affect the size of the housing 1.

[0056] More specifically, such as Figure 2As shown, the core assembly 3 also includes a core seat 34 and a take-up coil 35. The take-up coil 32 is used to wind up unused film tape, while the take-up coil 35 is used to wind up and collect used film tape. Both the take-up coil 35 and the take-up coil 32 are mounted on the core seat 34. The core seat 34 is provided with a first connecting rod and a second connecting rod. The take-up coil 32 is fitted onto the first connecting rod, and the take-up coil 35 is fitted onto the second connecting rod. The core seat 34 is mounted on the housing 1, and both the take-up coil 35 and the take-up coil 32 are mounted inside the housing 1 through the core seat 34. After the film tape is used up, it can be reused by replacing the core assembly 3 inside the housing 1, thereby reducing the cost of use. The core seat 34 is rotatably connected to the guide belt 33, making the installation of the guide belt 33 more stable and reliable.

[0057] More specifically, such as Figure 2 and Figure 3 As shown, a winding and unwinding assembly 5 is installed inside the housing 1. The winding and unwinding assembly 5 utilizes the principle of gear meshing rotation to enable the film belt to be wound and unwound normally during use. The winding and unwinding assembly 5 includes a gear seat 51, a large gear 52, and a waste pulley 53. Both the large gear 52 and the waste pulley 53 are mounted on the gear seat 51. A third connecting rod and a fourth connecting rod are provided on the gear seat 51. The large gear 52 is fitted onto the third connecting rod, and the waste pulley 53 is fitted onto the fourth connecting rod. The large gear 52 and the waste pulley 53 are connected through gear meshing. The winding and unwinding mechanism uses the gear seat 51 to install the large gear 52 and the waste pulley 53. The installation structure is simple and reliable. The large gear 52 is connected to the take-up ring 35, and the waste pulley 53 is connected to the take-up ring 35, enabling the winding and unwinding mechanism to drive the core assembly 3 to wind and unwind the film belt, making it labor-saving and convenient to use.

[0058] More specifically, such as Figures 2 to 4 As shown, a rotating shaft 332 is provided at one end of the guide belt 33. One end of the rotating shaft 332 is rotatably connected to the belt core seat 34, and the other end of the rotating shaft 332 is rotatably connected to the gear seat 51. The guide belt 33 is installed between the belt core seat 34 and the gear seat 51. The rotating shaft 332 is provided on the guide belt 33. The guide belt 33 rotatably connects the belt core seat 34 and the gear seat 51 through the rotating shaft 332. The rotating structure is more stable and reliable, and the rotation efficiency is higher.

[0059] Example 2

[0060] This embodiment provides a retractable correction tape based on Embodiment 1, such as... Figures 2 to 4As shown, the transmission assembly includes a protrusion 331 disposed on the guide belt 33 and a drive wall 413 disposed on the drive assembly 4. The transmission assembly is formed by the cooperation of the protrusion 331 and the drive wall 413. The protrusion 331 and the drive wall 413 abut against each other. When the drive assembly 4 is subjected to force, it drives the correction head 2 to slide backward. The drive assembly 4, through the transmission cooperation between the drive wall 413 and the protrusion 331, causes the guide belt 33 to rotate away from the drive assembly 4, resulting in higher transmission efficiency. On the other hand, the protrusion 331 is disposed on the guide belt 33 and the drive wall 413 is disposed on the drive assembly 4, resulting in a compact structure that does not increase the size of the correction belt and provides a better user experience.

[0061] More specifically, such as Figures 2 to 4 As shown, the drive assembly 4 is provided with a clearance portion 414 that is adapted to the protrusion 331. The clearance portion 414 is located on the rear side of the drive wall 413. When the drive assembly 4 drives the correction head 2 to extend, the drive assembly 4 slides forward relative to the protrusion 331, causing the protrusion 331 to enter the clearance portion 414. When the user applies force to the drive assembly 4 to drive the correction head 2 to slide forward, the drive assembly 4 slides forward relative to the guide belt 33. Under the tightening force of the film belt, the guide belt 33 rotates close to the drive assembly 4. At this time, the protrusion 331 of the guide belt 33 can enter the clearance portion 414 to make the overall structure more compact and save space.

[0062] More specifically, such as Figures 2 to 4 As shown, the protrusion 331 is semi-circular, which allows the protrusion 331 to increase the angle at which the guide belt 33 can be rotated and opened, thereby reducing the size of the guide belt 33 and saving the installation space of the guide belt 33. In this embodiment, the protrusion 331 can also be triangular, conical, etc., but this embodiment does not limit it and will not elaborate further.

[0063] Example 3

[0064] This embodiment provides a telescopic correction belt based on Embodiment 1. The transmission component includes a protrusion 331 disposed on the drive component 4 and a drive wall 413 disposed on the guide belt member 33 (the specific structure of this embodiment is not shown in the accompanying drawings, which can be referred to in Embodiment 2). The protrusion 331 and the drive wall 413 in Embodiment 2 are interchanged, and the protrusion 331 and the drive wall 413 abut against each other. The protrusion 331 is disposed on the drive component 4 and the drive wall 413 is disposed on the guide belt member 33. Through the abutment between the protrusion 331 and the drive wall 413, when the drive component 4 is subjected to force, it drives the correction head 2 to slide backward. The drive component 4 rotates away from the drive component 4 through the transmission cooperation between the protrusion 331 and the drive wall 413. The principle is the same as that of Embodiment 2, and the transmission efficiency is high.

[0065] More specifically, the guide belt 33 is provided with a clearance portion that matches the protrusion 331. The clearance portion is located on the rear side of the drive wall 413. When the drive assembly 4 drives the correction head 2 to extend, the drive assembly 4 slides forward relative to the protrusion 331, causing the protrusion 331 to enter the clearance portion. The protrusion 331 is provided on the drive assembly 4, and the clearance portion is provided on the guide belt 33. When the user applies force to the drive assembly 4 to drive the correction head 2 to slide forward, the drive assembly 4 slides forward relative to the guide belt 33. Under the tightening force of the membrane belt, the guide belt 33 rotates close to the drive assembly 4. At this time, the protrusion 331 of the drive assembly 4 can enter the clearance portion to make the overall structure more compact and save space.

[0066] More specifically, the protrusion 331 is semi-circular, which increases the angle at which the guide belt 33 can rotate and open, thereby reducing the size of the guide belt 33 and saving installation space. In this embodiment, the protrusion 331 can also be triangular, conical, etc., but this embodiment does not limit it and will not elaborate further.

[0067] Example 4

[0068] This embodiment provides a telescopic correction tape based on embodiment 2 or 3, wherein the clearance portion 414 has a cavity structure, that is, the portion of the drive assembly 4 located on the rear side of the drive wall 413 is a cavity. When the drive assembly 4 and the guide belt 33 rotate relative to each other and approach each other, the cavity accommodates the protrusion 331, so that the drive wall 413 can fit against the side wall of the guide belt 33, so that the film tape on the guide belt 33 can be released. The structure inside the correction tape is more compact, and the cavity structure saves materials and can reduce the production cost of the drive assembly 4.

[0069] Example 4

[0070] This embodiment provides a telescopic correction belt based on embodiment 2 or 3, wherein the clearance portion 414 has an inclined structure, which engages with the drive wall 413. The inclined structure has a guiding effect, making it easier for the protrusion 331 to enter the clearance portion 414. When the drive assembly 4 and the guide belt member 33 rotate relative to each other and approach each other, the protrusion 331 enters the clearance portion 414 through the guiding effect of the inclined structure, avoiding problems such as jamming, and is less labor-intensive and more reliable.

[0071] Example 5

[0072] This embodiment provides a telescopic correction tape based on embodiment 2 or 3. The clearance portion 414 is a cavity structure, meaning the portion of the drive assembly 4 located behind the drive wall 413 is a cavity. The sidewall of this cavity structure that engages with the protrusion 331 is an inclined surface. This inclined surface engages with the drive wall 413 and has a guiding effect, allowing the protrusion 331 to enter the clearance portion 414 more smoothly. When the drive assembly 4 and the guide belt member 33 rotate relative to each other and approach, the protrusion 331 enters the clearance portion 414 through the guiding effect of the inclined surface structure, avoiding problems such as jamming. This makes it easier to use and improves reliability. Furthermore, by accommodating the protrusion 331 through the cavity, the drive wall 413 can fit snugly against the sidewall of the guide belt member 33, allowing all the film on the guide belt member 33 to be released. The structure within the correction tape is more compact, and the cavity structure saves material, reducing the production cost of the drive assembly 4.

[0073] Example 6

[0074] This embodiment provides a retractable correction tape based on embodiment 2 or 3, such as Figure 2 As shown, the drive assembly 4 includes a drive base 41 and a push button 42. The drive base 41 is connected to the correction head 2, and a linkage part 411 is provided on the drive base 41, such as... Figure 5 and Figure 6 As shown, the housing 1 is provided with a sliding groove 12 that slides with the linkage part 411. The linkage part 411 passes through the sliding groove 12 and is connected to the push button 42. When the push button 42 is subjected to force, it drives the drive seat 41 to slide through the linkage part 411. The drive seat 41 is connected to the push button 42 through the linkage part 411. By setting the linkage part 411 to slide with the sliding groove 12, when the user applies force to the push button 42, the push button 42 acts on the linkage part 411, causing the linkage part 411 to slide within the sliding groove 12, thereby driving the drive seat 41 to slide on the housing 1. By setting the drive seat 41 to connect with the correction head 2, the sliding of the drive seat 41 drives the correction head 2 to extend and retract, and the sliding fit is good.

[0075] More specifically, such as Figure 4 and Figure 7 As shown, a mounting part 412 is provided at one end of the drive seat 41, and one end of the correction head 2 is fixed on the mounting part 412. One side of the mounting part 412 abuts against one side of the guide belt 33. The correction head 2 is fixed by the mounting part 412, making the structure of the drive seat 41 sliding to drive the correction head 2 to extend and retract more reliable, and the structure of fixing the correction head 2 is simpler. The drive seat 41 is set to abut against the guide belt 33 through the mounting part 412, so that when the drive seat 41 slides, the guide belt 33 is controlled to rotate in a direction away from the mounting part 412 through the mounting part 412. The cooperation between the mounting part 412 and the guide belt 33 is reliable, and the size of the mounting part 412 is small, so it will not affect the rotation of the guide belt 33, and the rotation efficiency is higher.

[0076] More specifically, such as Figure 3 and Figure 4 As shown, the drive wall 413 is the side wall of the mounting part 412. By configuring the side wall of the mounting part 412 as the drive wall 413, when the drive seat 41 slides backward, the drive wall 413 acts on the protrusion 331. The protrusion 331 is subjected to force, causing the guide belt 33 to rotate in a direction away from the mounting part 412. This results in better fit, higher rotation efficiency, and a simpler structure.

[0077] More specifically, such as Figure 5 and Figure 6 As shown, a locking part 121 is provided on the slide 12, and an elastic element 43 is installed on the linkage part 411, such as... Figure 7 As shown, a positioning part 431 adapted to the locking part 121 is formed on the elastic member 43. When the linkage part 411 slides in the slide groove 12, the driving seat 41 is slidably locked by engaging the positioning part 431 with the locking part 121. Figure 8 As shown, the push button 42 is provided with an unlocking part 421 that is adapted to the positioning part 431. When the user applies force to the push button 42, the unlocking part 421 is subjected to force, causing the positioning part 431 to undergo elastic deformation and disengage from the locking part 121, thereby allowing the drive seat 41 to slide and unlock. The sliding locking and unlocking means that when using the correction tape, the user does not need to constantly apply force to the push button 42 to keep the drive seat 41 and the correction head 2 in an extended or retracted state, making it more labor-saving and convenient to use, and providing a better user experience.

[0078] More specifically, such as Figure 5 , Figure 7 and Figure 8 As shown, the push button 42 is slidably engaged with the linkage part 411. The push button 42 can slide on the linkage part 411, and the push button 42 is subjected to force on the linkage part 411. By sliding, the unlocking part 421 acts on the positioning part 431, thereby enabling the positioning part 431 to disengage from the locking part 121 to achieve sliding unlock. The push button 42 is provided with a limit post 422, and the linkage part 411 is provided with a limit part 4111 adapted to the limit post 422. When the push button 42 is subjected to force and slides, the positioning part 431 disengages from the locking part 121 to achieve sliding unlock. The push button 42 continues to slide until the end of the limit post 422 abuts against the end of the limit part 4111, so that the push button 42 can drive the drive seat 41 to slide, thereby enabling the correction head 2 to extend and retract. The structure is simple and the use is labor-saving.

[0079] Example 7

[0080] This embodiment provides a retractable correction tape based on embodiment 2 or 3, wherein, as Figure 2 As shown, the drive assembly 4 includes a drive base 41 and a push button 42. The drive base 41 is connected to the correction head 2, and a linkage part 411 is provided on the drive base 41, such as... Figure 5 and Figure 6As shown, the housing 1 is provided with a sliding groove 12 that slides with the linkage part 411. The linkage part 411 passes through the sliding groove 12 and is connected to the push button 42. When the push button 42 is subjected to force, it drives the drive seat 41 to slide through the linkage part 411. The drive seat 41 is connected to the push button 42 through the linkage part 411. By setting the linkage part 411 to slide with the sliding groove 12, when the user applies force to the push button 42, the push button 42 acts on the linkage part 411, causing the linkage part 411 to slide within the sliding groove 12, thereby driving the drive seat 41 to slide on the housing 1. By setting the drive seat 41 to connect with the correction head 2, the sliding of the drive seat 41 drives the correction head 2 to extend and retract, and the sliding fit is good.

[0081] More specifically, such as Figure 4 and Figure 7 As shown, a mounting part 412 is provided at one end of the drive seat 41, and one end of the correction head 2 is fixed on the mounting part 412. One side of the mounting part 412 abuts against one side of the guide belt 33. The correction head 2 is fixed by the mounting part 412, making the structure of the drive seat 41 sliding to drive the correction head 2 to extend and retract more reliable, and the structure of fixing the correction head 2 is simpler. The drive seat 41 is set to abut against the guide belt 33 through the mounting part 412, so that when the drive seat 41 slides, the guide belt 33 is controlled to rotate in a direction away from the mounting part 412 through the mounting part 412. The cooperation between the mounting part 412 and the guide belt 33 is reliable, and the size of the mounting part 412 is small, so it will not affect the rotation of the guide belt 33, and the rotation efficiency is higher.

[0082] More specifically, such as Figure 3 and Figure 4 As shown, the drive wall 413 is the side wall of the mounting part 412. By configuring the side wall of the mounting part 412 as the drive wall 413, when the drive seat 41 slides backward, the drive wall 413 acts on the protrusion 331. The protrusion 331 is subjected to force, causing the guide belt 33 to rotate in a direction away from the mounting part 412. This results in better fit, higher rotation efficiency, and a simpler structure.

[0083] More specifically, such as Figure 9 As shown, a locking part 121 is provided on the slide groove 12, and a positioning part 431 adapted to the locking part 121 is provided on the linkage part 411. The positioning part 431 engages with the locking part 121 to achieve sliding locking, and the positioning part 431 disengages from the locking part 121 to achieve sliding unlocking. The locking part 121 is an elastic structure, or the positioning part 431 is an elastic structure, or both the locking part 121 and the positioning part 431 are elastic mechanisms. Figure 10As shown, in this embodiment, a strip groove 123 is provided on the side of the slide groove 12 near the locking part 121. The strip groove 123 makes the locking part 121 elastic. When the push button 42 is subjected to force, it drives the drive seat 41 to slide. The positioning part 431 engages with the locking part 121 through sliding to make the drive seat 41 slide and lock. When the push button 42 is subjected to force again, it drives the drive seat 41 to slide. The positioning part 431 and the locking part 121 are subjected to force and disengage from each other through elastic deformation, so that the drive seat 41 slides and unlocks. The structure is simpler and easier to manufacture and install.

[0084] More specifically, such as Figure 5 , Figure 7 and Figure 8 As shown, the push button 42 is slidably engaged with the linkage part 411. The push button 42 can slide on the linkage part 411, and the push button 42 is subjected to force on the linkage part 411. By sliding, the unlocking part 421 acts on the positioning part 431, thereby enabling the positioning part 431 to disengage from the locking part 121 to achieve sliding unlock. The push button 42 is provided with a limit post 422, and the linkage part 411 is provided with a limit part 4111 adapted to the limit post 422. When the push button 42 is subjected to force and slides, the positioning part 431 disengages from the locking part 121 to achieve sliding unlock. The push button 42 continues to slide until the end of the limit post 422 abuts against the end of the limit part 4111, so that the push button 42 can drive the drive seat 41 to slide, thereby enabling the correction head 2 to extend and retract. The structure is simple and the use is labor-saving.

[0085] Example 8

[0086] This embodiment provides a retractable correction tape based on embodiment 2 or 3, wherein, as Figure 11 As shown, the drive assembly 4 includes a drive base 41 and a push button 42 disposed on the drive base 41. The drive base 41 and the push button 42 are integrally formed. The push button 42 is cylindrical. The drive base 41 is connected to the correction head 2. The housing 1 is provided with a slide groove 12 that slides with the push button 42. The push button 42 extends through the slide groove 12. When the push button 42 is subjected to force, it drives the drive base 41 to slide. By setting the drive base 41 to slide with the housing 1 through the push button 42, the structure is simpler. When the user applies force to the push button 42, the push button 42 slides in the slide groove 12. The push button 42 drives the drive base 41 to slide on the housing 1. By setting the drive base 41 to be connected to the correction head 2, the sliding of the drive base 41 drives the correction head 2 to extend and retract. The sliding fit is better and the use is more labor-saving.

[0087] More specifically, both ends of the slide groove 12 are provided with limiting holes 122 that are adapted to the push button 42. The limiting holes 122 are C-shaped and have a certain amount of deformation. The push button 42 slides into the C-shaped limiting hole 122 under force and is locked with the limiting hole 122 to achieve sliding lock. The user can apply a large force to make the push button 41 disengage from the C-shaped limiting hole 122 to achieve sliding unlock.

However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
