For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0030] In the first embodiment of the present utility model, a tearable tape is provided. Refer to Figures 1 - 3 , which includes a fixing ring 1 and an adhesive tape 2; the fixing ring 1 has a circular contour. If it is set as an annular shape, it is convenient for the adhesive tape 2 to be wound to fix the adhesive tape 2; the fixing ring 1 can be made of hard paper or plastic.

[0031] Furthermore, the adhesive tape 2 is wound around the outer peripheral side of the fixing ring 1; the adhesive tape 2 is set as a single-sided adhesive tape 2 or a double-sided adhesive tape 2. When it is set as a single-sided adhesive tape 2, the adhesive side faces the winding direction of the adhesive tape 2, that is, towards the center of the fixing ring 1.

[0032] Furthermore, a tear guiding strip 3 is provided on the side edge of the adhesive tape 2; the side face of the tear guiding strip 3 facing the fixing ring 1 is set as a smooth layer 32 without adhesiveness. When the adhesive tape 2 is adhered to the surface of an article, the tear guiding strip 3 will not adhere to the article.

[0033] Furthermore, a plurality of first ribs 31 are arranged at intervals along the length direction of the tear guiding strip 3, and the hardness of the first ribs 31 is greater than that of the tear guiding strip 3; it should be noted that the hardness of the first ribs 31 can be increased by increasing the thickness or using a hardening agent.

When applying force to the first rib 31, the first rib 31 is convenient for driving the tearing tape 3 to move away from the surface of the adhered object together.

[0037] Furthermore, one end of the first rib 31 extends to the side of the tearing tape 3 away from the adhesive tape 2 to form a holding end 311, and the holding end 311 is used for the user to conveniently hold the first rib 31, so as to apply force to the first rib 31.

[0038] In another embodiment of the present utility model, the distance between the two first ribs 31 is less than 10 cm.

[0039] In another embodiment of the present utility model, the width of the tearing tape 3 is less than or equal to one-third of the width of the adhesive tape 2. The specific width of the tearing tape 3 is determined according to the width of the adhesive tape 2. For example, when the width of the adhesive tape 2 is less than 10 cm, the width of the tearing tape 3 is preferably set to 1 cm - 3 cm; when the width of the adhesive tape 2 is greater than or equal to 10 cm, the width of the tearing tape 3 is preferably set to 3 cm or more, so as to increase the pulling force of the tearing tape 3, make the tearing tape 3 not easily break, and be convenient for holding and applying force.

[0040] In another embodiment of the present utility model, refer to Figure 1 , the adhesive tape 2 is provided with a plurality of second ribs 21 corresponding to the first ribs 31 one by one; the second ribs 21 are used to guide the tearing direction of the adhesive tape 2, so as to facilitate the adhesive tape 2 to move away from the surface of the adhered object; the hardness of the second ribs 21 is greater than that of the adhesive tape 2, which is convenient for using the second ribs 21 to locate the adhesion position of the adhesive tape 2; the hardness of the second ribs 21 is less than or equal to the hardness of the first ribs 31, so as to facilitate the second ribs 21 to adapt to the surface shapes of different objects and facilitate the adhesion of the adhesive tape 2; the second ribs 21 are set in a long strip shape perpendicular to the length direction of the adhesive tape 2, which is convenient for the adhesive tape 2 to separate from the surface of the adhered object along its width direction.

[0041] Furthermore, refer to Figure 3, the adhesive tape 2 includes a first base layer 231 and a second base layer 232; the first base layer 231 covers the upper surface of the second base layer 232; an adhesive layer 24 is provided on the lower surface of the second base layer 232; the second rib 21 is provided between the first base layer 231 and the second base layer 232; the first base layer 231 and the second base layer 232 can be adhered together by glue or melting; both the first base layer 231 and the second base layer 232 are made of plastic film, and the adhesive layer 24 is made of EVA hot melt adhesive.

[0042] Further, referring to Figure 3 , in the embodiment of the single-sided adhesive tape 2, a non-stick layer 22 is provided on the upper surface of the first base layer 231 so that the adhesive layers are not easily adhered to each other when the adhesive tape is wound; the non-stick layer 22 is made of polypropylene material.

[0043] Further, referring to Figure 2 , the first base layer 231 and the second base layer 232 form a matrix layer 23, and the two side edges of the matrix layer 23 respectively extend outwards to form the whole of the tearing strip 3, so that the tearing strip 3 and the adhesive tape 2 are integrally connected and not easily separated; a smooth layer 32 is provided on the lower surface of the second base layer 232 at the tearing strip 3; the first rib 31 is provided between the first base layer 231 and the second base layer 232.
