[0002] Tape cutters are commonly used tools in daily life and can be used to cut materials such as adhesive tape and water-based tape. To prevent the tape from falling off during cutting, existing tape cutters often use a closed fixed design or a snap-on design. However, these existing cutters have many shortcomings, such as being inconvenient to use and having an inconvenient snap-on design.

[0003] For example, patent number "CN214879016U" describes a tape cutter that includes a frame body, a cutting blade, and a baffle. The baffle is equipped with a retaining ring that receives a sleeve of tape to be cut. The retaining ring also includes a buckle that passes through one side of the sleeve and secures it to the other side. This utility model is low-cost, easy to use, and not prone to damage.

[0004] As shown in the above patents or the prior art, tape applicators are generally suitable for single-sided tape. Since both sides of double-sided tape are sticky, the tape will stick to the inner wall of the cutter when it rotates in the cutter, resulting in it being unable to rotate and unable to achieve the effect of discharging. However, in some cases, double-sided tape needs to be used frequently, and people need to manually tear off the stickers on both sides of the double-sided tape, which is a complicated operation. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that double-sided tape needs to be frequently used in some cases, and the double-sided tape needs to be torn off manually, which is a complicated operation.
