[0040] Correction tape is a stationery item with correction and error-correcting functions, typically used to correct errors on paper. It typically consists of a housing, a rotating assembly, and a tape core. The core is wound around the rotating assembly, which rotates to release the tape. The tape core has a dressing that adheres to the paper or item being corrected, partially covering it.

[0041] The correction tape's rotating assembly consists of a waste pulley and a main pulley, both of which are connected by a transmission mechanism. The main pulley is equipped with a belt core, and the waste pulley is used to reel in the used belt core. In related technologies, to prevent the main pulley from rotating backward and causing the belt core to backslide, a cantilever hook structure is usually installed on the main pulley. The cantilever hook structure cooperates with a ratchet to limit the rotation direction of the main pulley. However, this limiting structure generates significant resistance to the belt core's movement and produces a loud noise, which affects the user's experience.

[0042] Based on this, the embodiment of the present disclosure provides a correction tape, such as Figure 1 、 Figure 2 As shown, the correction tape 10 includes a housing and a rotating assembly 200 .

[0044] The correction tape 10 provided by the present disclosure provides rotation damping for the first gear 210 by setting a protruding structure 211 on the inner hole of the first gear 210 of the rotating assembly 200, and provides pre-tightening force for the tape core 300 by the mutual abutment of the protruding structure 211 and the outer surface of the first support column 110, so as to prevent the tape core 300 from loosening when the correction tape 10 is subjected to external vibration and the like, and improve the user's use experience; the correction tape 10 provided by the present disclosure avoids the structure of preventing the tape core 300 from being reversed by setting cantilever hooks and ratchets on the second gear 220, reduces the noise generated when the correction tape 10 is used, reduces the running resistance, and simplifies the structure of the correction tape 10, and reduces the weight of the correction tape 10.

[0045] The various parts of the correction tape provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings:

[0046] The tape core 300 of the correction tape provided by the present disclosure can be a white non-transparent correction tape with the function of covering paper errors and allowing rewriting, can be a decorative tape with patterns with the function of decoration, or can be a covering tape with the function of covering, and the like. The coating on the tape core 300 can be white paint, double-sided tape, dot-shaped double-sided tape, or 2B pencil powder, and the like. The tape core 300 and the coating on the tape core 300 can be adaptively adjusted according to the actual use of the correction tape 10, and the correction tape protected by the present disclosure should be understood in a broad sense, and is not limited by the correction function.

[0047] The tape core 300 can include a tape body, and the tape body can include a double-layer structure. For example, the tape body can include a coating part and a release part arranged in a stack, the coating part adheres to one side of the release part, and the release part protects the coating part during storage, transportation and use of the correction tape.

The release part can be a flexible substrate such as a release paper tape or a PET plastic tape with a smooth surface, and the coating part can be white paint, double-sided tape, dot-shaped double-sided tape, or 2B pencil powder, and the like. The tape body can be made of materials and processes in the prior art, which will not be described in detail here.

[0048] In the embodiments provided by the present disclosure, as shown in Figure 8 , in combination with Figure 1 and Figure 11The correction tape 10 comprises a shell 100, which can be divided into an upper shell 101 and a lower shell 102, and the upper shell 101 and the lower shell 102 constitute a cavity, the cavity of the shell 100 is used for accommodating the rotating assembly 200, the tape core 300 and other structures, and the shell 100 provides protection and fixed support for the components inside it. The upper shell 101 and the lower shell 102 are provided with connecting structures, so that the upper shell 101 and the lower shell 102 can be connected to form a cavity structure. In the present disclosure, the specific form of the connecting structure is not limited, and it can be understood as a commonly used connecting method in the art.

[0049] As shown in Figure 10 , in combination with Figure 1 and Figure 11 , a protective sleeve 130 can also be provided outside the shell 100, the protective sleeve 130 is sleeved on the outer surface of the shell 100 and covers at least part of the surface of the shell 100, the protective sleeve 130 provides a protection function for the shell 100, and the strength of the shell 100 can be improved through the protective sleeve 130. Due to the protection function of the protective sleeve 130, the thickness of the shell 100 can be appropriately reduced during the manufacturing process of the shell 100, so as to reduce the overall weight of the correction tape 10. Of course, in the correction tape 10 provided in the present disclosure, the protective sleeve 130 can also not be provided, and the selection can be made according to the actual design requirements.

[0050] The outer surface of the protective sleeve 130 can be flush with the outer surface of the shell 100, and the position of the shell 100 sleeved on the protective sleeve 130 can be recessed towards the inside of the shell 100 to cooperate with the protective sleeve 130. When the shell 100 is sleeved on the protective sleeve 130, the outer surface of the protective sleeve 130 can be flush with the outer surface of the shell 100, improving the appearance and the user's holding comfort. Of course, the protective sleeve 130 can also be directly sleeved on the outer surface of the shell 100, and the protective sleeve 130 can protrude from the outer surface of the shell 100.

[0051] A non-slip part can be provided on the outer surface of the protective sleeve 130 or the shell 100, which facilitates the user to hold the protective sleeve 130 or the shell during use. The non-slip part can be a plurality of raised stripes provided on the protective sleeve 130 or the shell, or a plurality of protrusions, and different shapes, positions and other parameters of the non-slip part can be selected according to the actual use requirements or process requirements, and the present disclosure does not make specific limitations.

[0052] As shown in Figure 8 , in combination with Figure 1The housing 100 comprises a first support column 110 and a second support column 120 arranged inside the housing 100, and the first support column 110 and the second support column 120 have the same extension direction. The first support column 110 and the second support column 120 can be arranged on the upper housing 101 at the same time, or both can be arranged on the lower housing 102 at the same time. For example, the first support column 110 and the second support column 120 are arranged on the lower housing 102 at the same time, and both extend from the lower housing 102 to the upper housing 101 at the same time. The first support column 110 and the second support column 120 provide a mounting position for the rotating assembly 200, and can provide support for the correction tape 10. When the rotating shaft assembly rotates, the first support column 110 and the second support column 120 can limit the rotating assembly 200 to avoid movement of the rotating assembly 200, so that the rotation of the correction tape 10 is more stable and less likely to malfunction.

[0053] The first support column 110, the second support column 120 and the lower housing 102 can be integrally formed, or can be separately formed and connected. For example, the first support column 110, the second support column 120 and the lower housing 102 can be formed by integrally injection molding.

[0054] In the embodiments provided in the present disclosure, as shown in Figure 1 , in combination with Figure 2 , Figure 3 , Figure 4 and Figure 9 , the correction tape 10 comprises a rotating assembly 200 arranged inside the housing 100. The rotating assembly 200 comprises a first gear 210 and a second gear 220. The first gear 210 is arranged on the first support column 110 through an inner hole, and the second gear 220 is arranged on the second support column 120. In the present disclosure, the first gear 210 can be a waste tape wheel, which is used to wind the used tape core 300. The second gear 220 can be a tape feeding wheel, and the unused tape core 300 can be arranged on the second gear 220. The rotating assembly 200 is driven to rotate in a first direction by the second gear 220, so as to output the tape core 300. The first direction can be parallel to the main body of the tape head 400.

[0055] The rotating assembly 200 further comprises a third gear 230, the first gear 210 and the second gear 220 are engaged with the third gear 230 respectively, so that the third gear 230 is provided to ensure the good synchronization of the first gear 210 and the second gear 220 during use of the correction tape 10, the rotating assembly 200 runs stably and reliably, and the structure is compact; at the same time, the third gear 230 makes the rotational linear speed of the first gear 210 and the second gear 220 the same, ensures that the length of the tape core 300 is the same as the length of the first gear 210, and keeps the tape core 300 in a tight state, so as to facilitate the use of the tape core 300. In the present disclosure, the third gear 230 in the rotating assembly 200 can be one or more, the number and the setting position of the third gear 230 can be selected according to the actual structure and design requirements of the correction tape 10, of course, the third gear 230 can also not be provided in the correction tape 10, and other components with the same or similar effect can be used instead, and the present disclosure is not limited specifically.

[0056] In the structure of the correction tape 10, the unused tape core 300 and the used tape core 300 are integrated, and the unused tape core 300 and the used tape core 300 form a closed loop structure inside the shell 100 by being wound on the first gear 210 and the second gear 220.

[0057] The embodiments of the present disclosure take the first gear 210 as the waste tape wheel and the second gear 220 as the tape releasing wheel as an example for description, but the functions of the first gear 210 and the second gear 220 are not limited, and in actual use, adaptive changes and adjustments can be made according to the specific structure and use scene of the correction tape 10.

[0058] In the embodiments provided in the present disclosure, the tape core 300 is detachably arranged on the rotating assembly 200, and after use of the tape core 300, the used tape core 300 can be removed from the rotating assembly 200 to replace a new tape core. In the present disclosure, the first gear 210 and the second gear 220 can be suitable for various types of tape cores.

[0059] In the embodiments provided in the present disclosure, as shown in Figure 2 , Figure 3 and Figure 4 , in combination with Figure 1The hole wall of the inner hole of the first gear 210 is provided with at least one protruding structure 211, the protruding structure 211 abuts against the outer wall of the first supporting column 110, and the protruding structure 211 is used to provide pre-tightening force for the band core 300 to prevent the band core 300 from loosening. Since the protruding structure 211 and the first supporting column 110 form an abutting fit relationship, when the first gear 210 rotates, the protruding structure 211 can give the first supporting column 110 a certain rotational damping. Before the first use of the correction tape, especially during the transportation of the correction tape, this rotational damping can prevent the band core 300 from loosening and improve the initial use experience of the user. Of course, the above use scenario of the protruding structure 211 is only exemplary, and in other use environments, the protruding structure 211 can also prevent the band core 300 from loosening, which will not be described in detail here.

[0060] In an embodiment provided by the present disclosure, the number of protruding structures 211 can be one. One protruding structure 211 is arranged in the circumferential direction of the hole wall of the inner hole of the first gear 210, and the protruding structure 211 can surround the hole wall of the inner hole or can be partially arranged on the hole wall of the inner hole. For example, the protruding structure 211 can be a strip structure protruding from the hole wall of the inner hole. The protruding structure 211 can be arranged at the upper part, the middle part or the lower part of the inner hole of the first gear 210, and preferably, the protruding structure 211 is arranged at the middle part of the inner hole to increase the abutting area between the protruding structure 211 and the first supporting column 110, so that the rotational damping provided by the protruding structure 211 can meet the preset requirements.

[0061] In another embodiment provided by the present disclosure, the number of protruding structures 211 can be multiple, and multiple protruding structures 211 are arranged on the hole wall of the inner hole of the first gear 210 in a spaced manner. The multiple protruding structures 211 can be uniformly distributed along the circumferential direction of the hole wall of the inner hole. Each protruding structure 211 can be a strip structure protruding from the hole wall of the inner hole, or can be a point structure protruding from the hole wall of the inner hole, or can be another shape such as a rectangular structure, a triangular structure or a circular structure. The shapes and sizes of the protruding structures 211 can be the same or different. In the present disclosure, in order to ensure the uniformity of the rotational damping provided by the protruding structures 211 along the circumferential direction and avoid the first gear 210 from being stuck, preferably, the shapes and sizes of the protruding structures 211 are the same and are uniformly distributed on the hole wall of the inner hole of the first gear 210.

[0062] The height of the protruding structure 211 in the direction perpendicular to the inner hole wall of the first gear 210 and pointing to the center of the inner hole should not be too large to avoid excessive rotation damping and cause the first gear 210 to be stuck; the height of the protruding structure 211 should also not be too small to avoid providing insufficient rotation damping and failing to provide sufficient pre-tightening force for the band core 300. In the present disclosure, the height h of the protruding structure 211 can be 5mm≤h≤10mm, for example, the height h of the protruding structure 211 can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, etc. The normal rotation of the rotating assembly 200 is ensured, and sufficient pre-tightening force can be provided for the band core 300 to avoid loosening of the band core 300.

[0063] In the embodiments provided in the present disclosure, as shown in Figure 2 , Figure 3 shown, in combination with Figure 1 , the first gear 210 further comprises a plurality of cantilever structures 212 arranged in the circumferential direction of the inner hole, and the protruding structure 211 is arranged on the side of the cantilever structure 212 close to the center of the inner hole. The side of each cantilever structure 212 and the hole wall of the inner hole of the first gear 210 have a gap, so that the cantilever structure 212 has elasticity, and when the cantilever structure 212 contacts the outer wall of the first support column 110, the cantilever structure 212 can generate a certain elastic force to avoid the phenomenon of the first gear 210 being stuck with the first support column 110.

[0064] The plurality of cantilever structures 212 can be arranged at intervals in the circumferential direction of the inner hole, and there is a gap between the two adjacent cantilever structures 212. In order to ensure the uniformity of the rotation damping, preferably, the plurality of cantilever structures 212 are uniformly distributed in the circumferential direction of the inner hole of the first gear 210.

[0065] In the present disclosure, the protruding structure 211 is arranged on the cantilever structure 212, and the same number of protruding structures 211 can be arranged on each cantilever structure 212, or the number of protruding structures 211 arranged on each cantilever structure 212 can be different, for example, the number of protruding structures 211 arranged on one cantilever structure 212 is one, and the number of protruding structures 211 arranged on the adjacent cantilever structure 212 can be two; or the number of protruding structures 211 on the two adjacent cantilever structures 212 is two. The present disclosure does not make specific limitation on the corresponding relationship between the cantilever structure 212 and the protruding structure 211, and in actual application, it is only necessary to ensure the uniformity of the rotation damping provided by the protruding structure 211.

[0066] In the specific embodiments provided in the present disclosure, the number of cantilever structures 212 is three, the three cantilever structures 212 are uniformly distributed along the circumferential direction of the inner hole, and each cantilever structure 212 is provided with a protruding structure 211 on the side surface thereof, the protruding structure 211 can be in the shape of a bump, and the three protruding structures 211 are also uniformly distributed along the circumferential direction of the inner hole. After the rotating structure is assembled with the outer shell and the tape core 300, the protruding structure 211 abuts against the outer wall surface of the first supporting column 110, and the protruding structure 211 provides rotational damping for the first supporting column 110, so as to ensure that the tape core 300 will not be loosened.

[0067] In the embodiments provided in the present disclosure, the modulus of the gear in the rotating assembly 200 can be less than or equal to 1. Specifically, the modulus of the first gear 210 and the second gear 220 in the rotating assembly 200 is less than or equal to 1, for example, the modulus of both can be 0.75, 0.5 or 0.25, etc. The smaller the modulus of the gear, the more accurate the displacement of the tape core 300 of the correction tape 10, in addition, the reduction of the modulus of the gear reduces the amount of retreat of the tape core 300 when the correction tape 10 leaves the paper surface or the surface of the object, thereby improving the user experience.

[0068] In the embodiments provided in the present disclosure, as shown in Figure 5 , Figure 6 and Figure 7 , the first gear 210 and the second gear 220 are arranged in the rotating assembly 200. Figure 1The correction tape 10 further comprises a tape head 400 provided at the opening of the shell 100 and protruding from the opening, and the tape core 300 is wound around the tape head 400. The tape head 400 comprises a main body portion, and at least one groove structure 410 is formed at one end of the main body portion away from the opening. The groove structure 410 penetrates the main body portion in a direction perpendicular to the main body portion. When the correction tape 10 is used, the tape core 300 is pressed by the tape head 400, so that the paint portion on the tape core 300 is separated from the form portion, and the paint portion covers the surface of the paper or the object. At the same time, the tape head 400 facilitates the application of pressure to the tape core 300, so that the paint portion covers more smoothly and firmly. The provision of the groove structure 410 on the tape head 400 can reduce the overall weight of the tape head 400, increase the elasticity, flexibility and compliance of the tape head 400, and make the tape core 300 more compliant with the surface of the paper or the object to prevent the tape core 300 from being warped and improve the correction effect of the correction tape 10. Thirdly, because the groove structure 410 is provided on the tape head 400, the tape head 400 can apply greater pressure to the surface of the paper or the object under the same force, so that the paint portion of the tape core 300 covers the surface of the paper or the object more effectively and avoids the tape core 300 from being warped on the surface of the paper or the object due to insufficient pressure. Fourthly, because the flexibility and elasticity of the tape head 400 are increased, the cut surface of the tape core 300 remains complete after being cut, the phenomenon of the tape core 300 being dragged after being cut is avoided, and the integrity of the cut tape core 300 is ensured.

[0069] The number of groove structures 410 is at least one, and the groove structure 410 can be arranged inside the main body portion of the tape head 400 or at the edge position of the tape head 400.

[0070] In a specific embodiment provided in the present disclosure, the groove structure 410 can be arranged inside the main body portion of the tape head 400. Taking one groove structure 410 as an example, the groove structure 410 can be a through-hole structure, such as a circular through-hole, an elliptical through-hole, an oblong through-hole, a square through-hole, a rectangular through-hole or a sector through-hole. One groove structure 410 can be arranged at the side of the main body portion of the tape head 400 that applies pressure to the tape core 300, so as to improve the flexibility of the force application side of the main body portion of the tape head 400, make the tape core 300 more compliant with the surface of the paper or the object, and prevent the tape core 300 from being warped. The above embodiment is only exemplary, and in the present disclosure, the number of groove structures 410 can be multiple. The shapes of the multiple groove structures 410 can be the same or different, and the multiple groove structures 410 can be arranged in an array inside the main body portion of the tape head 400.

[0071] In another specific embodiment provided by the present disclosure, the groove structure 410 can be arranged at the edge position of the main body portion of the strap head 400, the groove structure 410 is arranged at the edge position of the two side edges intersecting with the force application side of the strap head 400, and the opening of the groove structure 410 is located at the edge position of the strap head 400, so that the opening direction of the groove structure 410 is the direction from the inside of the main body portion of the strap head 400 to the edge. The number of groove structures 410 is at least one, when the number of groove structures 410 is multiple, the multiple groove structures 410 can be symmetrically distributed on both sides of the symmetry axis of the main body portion of the strap head 400, or the multiple groove structures 410 are asymmetrically distributed, and the distribution of the multiple groove structures 410 on the edge of the main body portion of the strap head 400 can be selected according to the actual structure requirement.

[0072] Preferably, when the number of groove structures 410 is two, the two groove structures 410 are symmetrically arranged along the symmetry axis of the main body portion of the strap head 400, the two groove structures 410 are respectively recessed in the direction of the inside of the main body portion, the two groove structures 410 are opened in the second direction and the directions of the two openings are opposite, wherein the second direction is perpendicular to the first direction, and the plane where the first direction and the second direction are located is parallel to the surface of the main body portion of the strap head 400.

[0073] In the above embodiment, based on the opening width of the groove structure 410, in the second direction, the area of the groove structure 410 accounts for 55% to 70% of the area of the main body portion of the strap head 400. For example, the area of the groove structure 410 can be 55%, 60%, 65% or 70% of the area of the main body portion of the strap head 400, which can not only ensure that the groove structure 410 arranged in the main body portion can improve the flexibility of the strap head 400, but also ensure the strength of the strap head 400, and avoid the phenomenon of breakage of the main body portion of the strap head 400. For example, based on the opening width of the groove structure 410 being 3mm, when the width of the main body portion of the strap head 400 is 8mm, the depth of the groove structure 410 can be 2.5mm to 3mm. Of course, for different sizes of the main body portion of the strap head 400, the area of the groove structure 410 in the main body portion will be adaptively changed.

[0074] In another specific embodiment provided by the present disclosure, the groove structure 410 can be arranged at the edge position of the main body portion of the strap head 400, the groove structure 410 is arranged at the edge position of the two side edges intersecting with the force application side of the strap head 400, and the opening of the groove structure 410 is located at the edge position of the strap head 400, so that the opening direction of the groove structure 410 is the direction from the inside of the main body portion of the strap head 400 to the edge. The number of groove structures 410 is at least one, when the number of groove structures 410 is multiple, the multiple groove structures 410 can be symmetrically distributed on both sides of the symmetry axis of the main body portion of the strap head 400, or the multiple groove structures 410 are asymmetrically distributed, and the distribution of the multiple groove structures 410 on the edge of the main body portion of the strap head 400 can be selected according to the actual structure requirement.

[0075] The groove structure 410 can be one or a combination of multiple shapes such as a U-shaped groove, a V-shaped groove, a square groove, an arc-shaped groove, or a wavy groove. Preferably, a U-shaped groove is selected for ease of manufacture. It should be noted that the size, shape, and position of the groove structure 410 can be adjusted as needed according to the actual design requirements of the correction tape 10, and the embodiments provided in the present disclosure are only exemplary and do not limit the specific structure of the tape head 400 of the correction tape.

[0076] In the embodiments provided in the present disclosure, as shown in Figure 6 and Figure 7 , in combination with Figure 1 , the tape head 400 of the correction tape further includes a baffle assembly 420, which is arranged on the side of the main body portion away from the groove structure 410. The baffle assembly 420 is used to prevent the tape core 300 from being drawn in the second direction. The baffle assembly 420 and the surface of the main body portion of the tape head 400 can be arranged perpendicular to each other. The baffle assembly 420 is arranged between the force application position of the tape head 400 and the groove structure 410. When the tape core 300 is drawn, the baffle assembly 420 can limit the displacement of the tape core 300 to prevent the tape core 300 from being displaced laterally and separated from the tape head 400. In addition, when the correction tape 10 is subjected to reverse force to draw the tape core 300 in reverse, due to the action of the baffle assembly 420, when the baffle assembly 420 touches the surface of the paper or the object, there is still a gap between the tape core 300 and the surface of the paper or the object at this time. At this time, the tape core 300 is limited and cannot be drawn in reverse. In the present disclosure, the arrangement of the baffle assembly 420 can prevent the tape core 300 from being drawn in reverse, and the use of a cantilever hook structure is avoided, the structure of the correction tape 10 is simplified, and the use noise is reduced, achieving the purpose of silence.

[0077] In a specific embodiment provided in the present disclosure, taking a correction tape with a tape core of a large length (at least 30 meters long) as an example, when the tape core 300 is drawn to a length (hereinafter referred to as the drawn length) of 1 m, the drawn force of the tape core 300 in the related art is 280 g to 300 g, while in the present disclosure, the drawn force of the tape head with the groove structure 410 is 230 g to 250 g. Specifically, it can be 230 g, 240 g, or 250 g. The correction tape provided in the present disclosure saves 10% to 20% of the force relative to the correction tape in the related art when the drawn length is 1 m.

[0078] In an embodiment of the present disclosure, taking the correction tape with a long tape core (the length of which is at least 30 m) as an example, when the length of the tape is 15 m, the tape force of the tape core 300 in the related art is 400 g to 470 g, while the tape force of the tape head with the groove structure 410 in the present disclosure is 300 g to 350 g, specifically, 300 g, 310 g, 320 g, 330 g, 340 g or 350 g. The correction tape provided in the present disclosure saves 30% to 35% of force relative to the correction tape in the related art when the length of the tape is 15 m.

[0079] In an embodiment of the present disclosure, taking the correction tape with a long tape core (the length of which is at least 30 m) as an example, when the length of the tape is 30 m, the tape force of the tape core 300 in the related art is 700 g to 900 g, while the tape force of the tape head with the groove structure 410 in the present disclosure is 400 g to 500 g, specifically, 400 g, 410 g, 420 g, 430 g, 440 g, 450 g, 460 g, 470 g, 480 g, 490 g or 500 g. The correction tape provided in the present disclosure saves 45% to 55% of force relative to the correction tape in the related art when the length of the tape is 30 m.

[0080] For the correction tape, the greater the length of the tape core, the greater the required pressure. In the present disclosure, the greater the length of the tape core 300, the more force is saved relative to the correction tape in the related art, thereby saving force and greatly improving the user's experience.

[0081] It should be noted that in the above embodiments, the tape force of the tape core is measured in grams, and the specific measurement method is to cover the paper on the electronic scale or other measurement tools, and then measure the weight of the force generated by the correction tape during the corresponding length of the tape on the paper. Of course, the tape force of different correction tapes (including the correction tape in the present disclosure and the correction tape in the related art) can also be measured by other measurement methods, and the measurement unit and specific data can be adapted according to different measurement methods. The converted data is within the data range provided in the above embodiments, and the data obtained by other tape force measurement is not described in detail in the present disclosure. In the embodiments of the present disclosure, as shown in FIG. 1, the tape core 300 is provided with a groove structure 410, and the groove structure 410 is provided with a plurality of grooves 420. Figure 1 、 Figure 11 and Figure 12As shown, the correction tape 10 further comprises a tape head cover 430, which is adapted to the tape head 400 and is arranged on the side of the tape head 400 away from the shell, and the tape head cover 430 can contain at least part of the tape head 400 or expose the tape head 400. The tape head cover 430 plays a protective role for the tape head 400 and the tape core 300 arranged on the tape head 400, preventing them from being damaged during transportation and storage, and can also prevent the tape core 300 from losing adhesion of the paint part due to exposure to air. The tape head cover 430 and the shell 100 can be arranged separately, and the tape head cover 430 can be directly plugged in or out during use of the correction tape 10, or the tape head cover 430 and the shell 100 have a connection part, and the tape head cover 430 is still connected to the shell 100 during use of the correction tape 10, avoiding loss of the tape head cover 430.

[0082] In the embodiments provided in the present disclosure, as shown in Figure 1 As shown, the correction tape 10 further comprises a buffer 202 and a damping shaft 201, the buffer 202 is arranged between the second gear 220 and the tape core 300, and the buffer 202 is used to drive the tape core 300 to rotate synchronously with the second gear 220. The damping shaft 201 is arranged through the second gear 220, the tape core 300 and the shell 100, and the buffer 202 is arranged between the second gear 220 and the tape core 300. By adjusting the fitting depth between the damping shaft 201 and the second gear 220, the buffer force value of the buffer 202 can be adjusted. The buffer 202 can apply pressure to the second gear 220 and form a rotational pre-tightening force of the second gear 220. By adjusting the length of the buffer 202 to adjust the size of the pre-tightening force, the transmission synchronization between the rotating assembly 200 is ensured. For example, the buffer 202 can be a buffer spring. In order to ensure the synchronization of the rotating assembly 200, and to ensure that the tape core 300 can normally draw the tape and will not drag the tape core 300, the buffer spring needs to have a spring value in a suitable range, for example, the spring value of the buffer spring can be 250 grams to 550 grams, wherein grams represents the size of the force received by an object with a mass of one gram.

[0083] In the embodiments provided in the present disclosure, as shown in Figure 1 As shown, the correction tape 10 further comprises an inner ring 203, the tape core 300 is arranged on the inner ring 203, and the inner ring 203 cooperates with the second gear 220. The structure of the inner ring 203 is the same as or similar to that of the conventional inner ring 203 of the correction tape 10, which will not be described in detail here. In the present disclosure, under the condition allowed by the cavity space of the shell 100, a larger diameter inner ring 203 can be selected, which is more labor-saving when the tape core 300 draws the tape and improves the user's experience. The specific size of the diameter of the inner ring 203 can be adjusted according to the size of the shell 100, the size of the rotating assembly 200 and other components.

[0084] The correction tape 10 provided by the present disclosure provides rotation damping for the first gear 210 by setting a protruding structure 211 on the inner hole of the rotating assembly 200, and provides pre-tightening force for the tape core 300 by the mutual abutment of the protruding structure 211 and the outer surface of the first support column 110, preventing the tape core 300 from loosening when the correction tape 10 is subjected to external shocks and the like, and improving the user's use experience; The correction tape 10 provided by the present disclosure avoids the structure of preventing the tape core 300 from being reversed by setting cantilever hooks and ratchets on the second gear 220, reduces the noise generated when the correction tape 10 is used, reduces the running resistance, and simplifies the structure of the correction tape 10, and reduces the weight of the correction tape 10.
