[0002] The traditional correction belt includes an outer shell, a belt nozzle, a feed wheel, a take-up wheel and a core belt. An opening is opened on the side of the outer shell, and the belt nozzle is exposed to the outside from the opening; the feed wheel and the take-up wheel can be rotatably installed in the inner cavity of the outer shell, and the feed wheel drives the take-up wheel to rotate through a gear set; the core belt is installed on the wheel shaft of the feed wheel; a first guide shaft and a second guide shaft are provided in the inner cavity of the outer shell, the first guide shaft is located on one side between the feed wheel and the take-up wheel, and the second guide shaft is located between the belt nozzle and the take-up wheel, the feed wheel rotates clockwise, and the take-up wheel rotates counterclockwise; the free end of the core belt is unwound from the feed wheel in a clockwise direction, passes around the first guide shaft, the belt nozzle, and the second guide shaft in turn, and is fixed on the take-up wheel.
[0003] When using correction tape, the core tape is adhered to the paper surface by applying force to the nozzle. However, students are prone to misoperation during use, causing the core tape, which is stretched tight on the nozzle, to become loose. This can cause the core tape to deflect on the nozzle, causing it to detach from the nozzle and become tangled or knotted, increasing wear and tear on the core tape and shortening the service life of the correction tape. Utility Model Content
[0004] The problem to be solved by the utility model is to provide a correction tape nozzle anti-slip device, which can prevent the core tape from detaching from the tape nozzle, reduce the loss of the core tape, and extend the service life of the correction tape.
[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:
[0006] A correction tape nozzle anti-slip device comprises a nozzle body, a tape guide plate extending along the forward direction of the correction tape core is provided on the nozzle body, the front end of the tape guide plate is a nozzle tip, and the left and right sides of the tape guide plate are respectively provided with guide side plates for guiding the correction tape core; it is characterized in that: the inner sides of the upper edges of the two guide side plates are respectively provided with blocking blocks, the two blocking blocks correspond to each other and are located above the tape guide plate.
[0007] The above-mentioned definitions of inside and outside are: with the center of the tape guide plate as the reference, the side close to the center of the tape guide plate is the inside, and the side away from the center of the tape guide plate is the outside.
[0008] During installation, the core tape of the correction tape passes through the tape guide plate, and the left and right sides of the core tape are restrained between the two guide side plates. The upper left edge of the core tape is blocked by the left blocking block, and the upper right edge of the core tape is blocked by the right blocking block. When the correction tape is in use, the core tape is prevented from deflecting between the two guide side plates by the two blocking blocks, thereby preventing the core tape from detaching from the tape nozzle, reducing core tape wear, and extending the service life of the correction tape.
[0009] In a preferred embodiment, the cross-sectional area of the two blocking blocks gradually increases from front to back. By this arrangement, the blocking effect of the blocking blocks on the core belt can be enhanced, further preventing the core belt from detaching from the belt mouth.
[0010] In a further preferred embodiment, the inner side surface of the blocking block is an inclined surface, which guides the core belt and enables the core belt to be easily guided between the blocking block and the belt guide plate during assembly.
[0011] In a preferred embodiment, the guide side plates include a rear side plate and a front oblique side plate connected sequentially from back to front. The upper side edges of the front oblique side plates gradually slope downward from back to front, and the outer sides of the blocking blocks are integrally connected to the upper sides of the corresponding front oblique side plates. This provides a more stable connection between the blocking blocks and the guide side plates, and the inclined design of the front oblique side plates helps guide the movement of the core belt and reduce the resistance of the core belt on the belt nozzle.
[0012] In a further preferred embodiment, the lower surface of the blocking block gradually slopes downward from the back to the front, and the lower surface of the blocking block corresponds to the upper surface of the belt guide plate. This arrangement allows the lower surface of the blocking block to better adapt to the movement trajectory of the core belt, allowing the core belt to pass through the belt nozzle more smoothly and reducing wear on the core belt.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] The core belt of the utility model is not easy to deflect between the two guide side plates when blocked by the two blocking blocks, and can prevent the core belt from being separated from the belt mouth, thereby reducing the loss of the core belt and extending the service life of the correction belt.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] like Figure 1-5 As shown, the correction tape nozzle anti-slip device in this embodiment includes a nozzle body 1, and the nozzle body 1 is provided with a guide plate 11 extending along the forward direction of the correction tape core 2, the front end of the guide plate 11 is a nozzle tip 111, and the left and right sides of the guide plate 11 are respectively provided with guide side plates 12 for guiding the correction tape core 2; the inner sides of the upper edges of the two guide side plates 12 are respectively provided with blocking blocks 13, and the two blocking blocks 13 correspond to each other and are located above the guide plate 11.
[0022] The above-mentioned definitions of inside and outside are: taking the center of the tape guide plate 11 as a reference, the side close to the center of the tape guide plate 11 is the inside, and the side away from the center of the tape guide plate 11 is the outside.
[0023] During installation, the core tape 2 of the correction tape passes over the tape guide plate 11, and the left and right sides of the core tape 2 are restrained between the two guide side plates 12. The upper left edge of the core tape 2 is blocked by the left blocking block 13, and the upper right edge of the core tape 2 is blocked by the right blocking block 13. When the correction tape is in use, the core tape 2 is prevented from deflecting between the two guide side plates 12 by the two blocking blocks 13, thereby preventing the core tape 2 from detaching from the tape nozzle, reducing the wear of the core tape 2, and extending the service life of the correction tape.
[0024] The cross-sectional area of two stoppers 13 gradually becomes larger from front to back. By this arrangement, the blocking effect of stoppers 13 to core band 2 can be strengthened, and core band 2 can be further prevented from breaking away from the belt mouth.
[0025] The inner side surface of the blocking block 13 is a bevel 131. The inner side surface of the blocking block 13 is designed as a bevel 131, which guides the core belt 2 and enables the core belt 2 to be easily introduced between the blocking block 13 and the belt guide plate 11 during assembly.
[0026] The guide side plates 12 include a rear side plate 121 and a front oblique side plate 122, which are connected in sequence from back to front. The upper side of the front oblique side plate 122 gradually slopes downward from back to front, and the outer side of the blocking block 13 is integrally connected to the upper side of the corresponding front oblique side plate 122. The connection between the blocking block 13 and the guide side plate 12 is more stable. At the same time, the inclined design of the front oblique side plate 122 helps guide the movement of the core belt 2 and reduce the resistance of the core belt 2 on the belt nozzle.
[0027] The lower surface of the blocking block 13 gradually slopes downward from the back to the front, and the lower surface of the blocking block 13 corresponds to the upper surface of the belt guide plate 11. Through this arrangement, the lower surface of the blocking block 13 can better adapt to the movement trajectory of the core belt 2, making the core belt 2 smoother when passing through the belt nozzle, reducing the wear of the core belt 2.
[0028] In addition, it should be noted that the names of the various parts of the specific embodiments described in this specification may be different. Any equivalent or simple changes made based on the structure, features, and principles described in the concept of this utility model patent are included in the scope of protection of this utility model patent.
