[0049] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0050] As Figures 1-8 shown, the telescopic correction tape of the embodiment comprises a dispenser 1, and further comprises:

[0051] A shell 2, one end of the shell 2 is provided with a first opening 21, and the other end of the shell 2 is provided with a second opening 22;

[0052] A rotary driving module 3, the rotary driving module 3 comprises a rotary part 31 and a sliding part 32, the rotary part 31 is provided with a rotary driving part 311, the sliding part 32 is provided with a sliding driving part 321, and the rotary driving part 311 and the sliding driving part 321 abut together;

[0053] Wherein, the rotary part 31 is rotatably arranged in the second opening 22, the sliding part 32 and the dispenser 1 are connected, and the sliding part 32 and the dispenser 1 are slidably arranged in the shell 2 respectively, and the applicator 11 of the dispenser 1 is adjacent to the first opening 21;

[0054] The rotary part 31 is configured to rotate in the second opening 22 to push the sliding driving part 321 towards the first opening 21 direction through the rotary driving part 311, and the sliding part 32 is configured to drive the dispenser 1 to slide towards the first opening 21 direction at the same time.

[0055] Specifically, the telescopic correction tape provided by the embodiment meets the requirements of tape storage and use by adopting the dispenser 1, and the specific structure of the dispenser 1 can refer to conventional technology, which is not limited here.

[0056] In order to protect the dispenser 1 while meeting the design requirements of compact and miniaturized structure, the dispenser 1 is slidably disposed in the housing 2, and the applicator 11 of the dispenser 1 can extend out from the first opening 21 to meet the needs of use.

[0057] To ensure that the dispenser 1 can slide within the housing 2 while also meeting the overall miniaturization design requirements, a rotary drive module 3 is used to drive the dispenser 1 to slide within the housing 2. Specifically, the rotating component 31 can rotate within the second opening 22 of the housing 2. The rotary drive part 311 of the rotating component 31 cooperates with the sliding drive pump of the sliding component 32, converting the rotational motion of the rotating component 31 into the linear sliding motion of the sliding component 32, thereby driving the dispenser 1 to move within the housing 2 via the sliding component 32.

[0058] Because the rotating component 31 rotates, during use, the user only needs to rotate the rotating component 31 by hand to drive the dispenser 1 to move via the sliding component 32. Compared to the direct pressing method, the rotating component 31 makes the overall structure more compact.

[0059] To improve reliability and facilitate user disassembly and replacement of dispenser 1, the telescopic correction belt also includes a reset assembly 33. The reset assembly 33 includes a reset spring 331 and a reset mounting base 332. The reset mounting base 332 is provided with a through channel 3321 and is disposed in the housing 2.

[0060] The sliding component 32 is also provided with a stop part 322, the sliding component 32 passes through the through channel 3321, and the reset spring 331 is clamped between the stop part 322 and the reset mounting base 332.

[0061] Specifically, during the rotation of the rotating component 31 so that the sliding drive part 321 slides from the crest to the trough, the return spring 331 applies a spring force to the sliding component 32, so that the sliding drive part 321 can fit tightly against the rotating drive surface 312, improving the smoothness of use.

[0062] By using a reset mounting base to install the reset spring, the reset mounting base can be reliably assembled in the housing, ensuring that the spring can be securely and reliably assembled in the housing. Therefore, when replacing the distributor, since the reset spring is sandwiched between the reset mounting base and the stop of the sliding component, the reset spring can still obtain effective support from the reset mounting base when disassembling the distributor, thus avoiding the situation where the reset spring comes off, improving the reliability of the telescopic correction tape and the user experience.

[0063] Further, the shell 2 comprises a first shell 23 and a second shell 24, the first shell 23 is provided with a first opening 21, the second shell 24 is provided with a second opening 22, and the first shell 23 and the second shell 24 are detachably connected together.

[0064] The second shell 24 is further provided with a clamping portion 241, and the reset mounting seat 332 is clamped on the clamping portion 241.

[0065] Specifically, in order to facilitate the assembly of the reset mounting seat 332, so that the reset mounting seat 332 is fixed in the shell 2, the second shell 24 can be provided with a clamping portion 241, which can make the reset mounting seat 332 quickly clamped in the second shell 24, thereby meeting the requirement of installing the reset spring 331.

[0066] The performance entity of the clamping portion 241 can have various forms, for example: two clamping protrusions can be formed on the inner wall of the second shell 24, a clamping space is formed between the two clamping protrusions, and the reset mounting seat 332 can be clamped between the two clamping protrusions.

[0067] Alternatively, a clamping groove can be formed on the inner wall of the second shell 24, and the reset mounting seat 332 is clamped in the clamping groove.

[0068] Further, the reset mounting seat 332 is further provided with a support pipe 3322, and the support pipe 3322 communicates with the through channel 3321;

[0069] The sliding component 32 is inserted in the support pipe 3322;

[0070] The rotating component 31 is sleeved outside the support pipe 3322 or inserted in the support pipe 3322.

[0071] Specifically, since the rotating component 31 needs to rotate in the second opening 22, in order to enable the rotating component 31 to rotate smoothly when the user rotates the rotating component 31 to ensure smooth driving of the sliding component 32, the rotating component 31 is supported between the support pipe 3322 and the second opening 22. The two ends of the rotating component 31 are supported by the support pipe 3322 and the second opening 22 respectively, so that the rotating component 31 can rotate smoothly.

[0072] Further, the outer wall of the sliding component 32 is provided with a guide rib 323, the inner wall of the support pipe is provided with a guide groove 3323, and the guide rib 323 is slidably arranged in the guide groove 3323.

[0073] Specifically, in order to further guide the sliding of the sliding part 32, the guiding groove 3323 formed by the through channel 3321 can be used to guide the sliding of the sliding part 32 in the shell 2 by cooperating with the guide rib 323 on the sliding part 32. On the one hand, the sliding part 32 can slide smoothly, and on the other hand, the sliding part 32 can only slide in the shell 2 without rotating.

[0074] The guide rib 323 extends along the sliding direction of the sliding part 32 to meet the sliding guiding requirements of the sliding part 32.

[0075] Further, the rotating driving part 311 forms a rotating driving curved surface 312, and the sliding driving part 321 abuts against the rotating driving curved surface 312.

[0076] During the rotation of the rotating part 31 to drive the sliding part 32 to move towards the first opening 21, the distance between the position where the sliding driving part 321 contacts the rotating driving curved surface 312 and the first opening 21 gradually decreases.

[0077] Specifically, during the rotation of the rotating part 31 by the user, the rotating driving curved surface 312 abuts against the sliding driving part 321 by virtue of its curved surface structure, and the sliding driving part 321 can realize the sliding of the sliding part 32 in the shell 2 under the curved surface structure of the rotating driving curved surface 312.

[0078] During the movement of the dispenser 1 driven by the sliding part 32 to make the applicator 11 extend out of the first opening 21, the distance between the position where the sliding driving part 321 contacts the rotating driving curved surface 312 and the first opening 21 gradually decreases. Conversely, during the retraction of the applicator 11 into the inside of the first opening 21, the distance between the position where the sliding driving part 321 contacts the rotating driving curved surface 312 and the first opening 21 gradually increases.

[0079] Further, the rotating driving curved surface 312 is annular and is distributed around the axis of the rotating part 31.

[0080] The rotating driving curved surface 312 is a wave surface.

[0081] When the sliding driving part 321 abuts against the wave peak of the rotating driving curved surface 312, the applicator 11 of the dispenser 1 extends to the outside of the first opening 21.

[0082] When the sliding driving part 321 abuts against the wave valley of the rotating driving curved surface 312, the applicator 11 of the dispenser 1 retracts to the inside of the first opening 21.

[0083] Specifically, in order to facilitate the user to use 360 degrees, for the rotating drive curved surface 312, the rotating drive curved surface 312 is annular as a whole and is distributed around the axis of the rotating part 31. At the same time, in order to meet the requirement of the sliding part 32 reciprocating sliding, the rotating drive curved surface 312 is a wave surface. That is, along the axis of the rotating part 31, the sliding drive part 321 alternately contacts the wave peak part and the wave valley part of the rotating drive curved surface 312 in the rotating process of the rotating part 31. In this way, the requirement of the dispenser 1 to reciprocate in the shell 2 can be met.

[0084] At the same time, due to the adoption of the wave surface of the rotating drive curved surface 312, the rotating part 31 can smoothly drive the sliding part 32 to reciprocate in the process of converting the rotation into linear motion by the cooperation of the rotating drive curved surface 312 and the sliding drive part 321, so as to improve the use smoothness and convenience.

[0085] Further, the wave peak part of the rotating drive curved surface 312 is provided with a positioning gap 313;

[0086] After the applicator 11 of the dispenser 1 extends to the outside of the first opening 21, the sliding drive part 321 is located in the positioning gap 313.

[0087] Specifically, in order to position the sliding part 32 by cooperating the rotating part 31 and the sliding part 32 after the applicator 11 extends to the outside of the first opening 21 of the shell 2, the sliding drive part 321 will be located in the positioning gap 313 after sliding to the wave peak part of the rotating drive curved surface 312, so as to realize the positioning of the position of the sliding part 32; without rotating the rotating part 31, the sliding part 32 can keep the position unchanged, so as to ensure that the applicator 11 extending to the outside of the first opening 21 of the shell 2 keeps still, so as to improve the reliability of use.

[0088] Further, the rotating part 31 is in a tubular structure, and the rotating drive part 311 is a protruding structure formed on the inner tube wall of the rotating part 31;

[0089] The sliding part 32 is in a rod structure, and the sliding drive part 321 is protruding from the side wall of the sliding part 32.

[0090] Specifically, in order to facilitate assembly and improve the connection reliability between the rotating part 31 and the sliding part 32, the rotating part 31 is in a tubular structure as a whole, and the sliding part 32 is in a rod structure as a whole. The sliding part 32 is inserted into the rotating part 31, so that the sliding drive part 321 and the rotating drive part 311 on the inner tube wall of the rotating part 31 can reliably abut together.

[0091] The sliding driving part 321 can be a cylinder or a sliding block formed on the side wall of the sliding part 32 to meet the abutting contact with the rotating driving part 311 in the inner tube wall of the rotating part 31.

[0092] Further, the inside of the rotating part 31 is formed with a first inner tube segment 314 and a second inner tube segment 315, the diameter of the first inner tube segment 314 is larger than that of the second inner tube segment 315, and the rotating driving part 311 is formed on the first inner tube segment 314.

[0093] The sliding part 32 is inserted into the first inner tube segment 314, and the end of the sliding part 32 is located in the second inner tube segment 315.

[0094] Specifically, the rotating part 31 is formed with a stepped tube segment structure, the first inner tube segment 314 where the rotating driving part 311 is located has a larger diameter to meet the abutting connection of the sliding driving part 321 and the rotating driving part 311, and the second inner tube segment 315 has a smaller diameter to guide and support the end of the sliding part 32, so that the sliding part 32 can smoothly slide.

[0095] Further, the sliding part 32 can drive the dispenser 1 to move outward, and can also drive the dispenser 1 to move inward and reset under the action of the reset spring 331.

[0096] Therefore, the sliding part 32 is clamped with the dispenser 1. Specifically, the end of the sliding part 32 is provided with a clamping groove, and the dispenser 1 is provided with a mushroom head clamped in the clamping groove.

[0097] Alternatively, the sliding part 32 is threadedly connected with the dispenser 1. Specifically, the sliding part 32 is provided with an external thread part, the dispenser 1 is provided with an internal thread hole, and the external thread part is threadedly connected in the internal thread hole.

[0098] Compared with the prior art, the advantages and positive effects of the utility model are that: by increasing the rotating driving module 3 on the shell 2, the sliding part 32 of the rotating driving module 3 is connected with the dispenser 1 to drive the dispenser 1 to slide in the shell 2, so that the applicator 11 can be stretched out to the outside of the shell 2 for use, and for the sliding part 32, it is driven by the rotating part 31, in the rotating process, the rotating driving part 311 cooperates with the sliding driving part 321, so that the rotating operation of the rotating part 31 is converted into the linear motion of the sliding part 32, so that the overall structure is more compact, and the use convenience and user experience of the telescopic correction tape are improved.

[0099] Finally, it should be noted that: the above examples are used to illustrate the technical solutions of the present application, but not limited to; although the present application is described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still be modified to the technical solutions recorded in the foregoing examples, or part of the technical features are replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
