[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Referring to Figures 1-3 , an embodiment provided by the present utility model: A residue-free tape includes a film layer 4. A wear-resistant layer 5 is fixedly connected to the upper part of the film layer 4. The wear-resistant layer 5 can improve the wear resistance of the film layer 4 and is very convenient to use. The thickness of the wear-resistant layer 5 is half of the thickness of the film layer 4. A plurality of grooves 401 are provided in the lower part of the film layer 4. The longitudinal cross-sectional shape of the grooves 401 is rectangular. An adhesive layer 3 is provided below the film layer 4. A bump 301 is fixedly connected to the upper part of the adhesive layer 3. The cross-sectional shape of the bump 301 is long strip-shaped. The adhesive layer 3 adheres to the film layer 4. The bump 301 is adapted to the groove 401. A stress layer 2 is bonded below the adhesive layer 3. The lower part of the adhesive layer 3 can pass through the stress layer 2. The stress layer 2 includes a horizontal stress piece 201, a vertical stress piece 202 and a vertical stress column 203.

[0019] During use, peel off the release paper layer 1, and the adhesive layer 3 can be attached to an object to play an adhesive role. When tearing is needed, the wear-resistant layer 5 and the film layer 4 can drive the stress-bearing layer 2 to move. The stress-bearing layer 2 can provide an upward force to the adhesive layer 3, and under the mutual adhesion of the convex block 301 and the groove 401, another upward force is provided, thereby increasing the tearing tensile force. Moreover, the transverse stress-bearing piece 201 and the longitudinal stress-bearing piece 202 can reduce the attachment area of the adhesive layer 3 and the adhesion force of the adhesive layer 3, so that no adhesive remains, and it is convenient to use.

[0020] By providing the stress-bearing layer 2, the convex block 301 and the groove 401, the attachment area of the adhesive layer 3 can be reduced, the adhesion force of the adhesive layer 3 can be decreased, the tearing tensile force can be increased, and the connection strength between the film layer 4 and the adhesive layer 3 can be improved, so that no adhesive remains and it is convenient to use.

[0021] Working principle: During use, peel off the release paper layer 1, and the adhesive layer 3 can be attached to an object to play an adhesive role. When tearing is needed, the wear-resistant layer 5 and the film layer 4 can drive the stress-bearing layer 2 to move. The stress-bearing layer 2 can provide an upward force to the adhesive layer 3, and under the mutual adhesion of the convex block 301 and the groove 401, another upward force is provided, thereby increasing the tearing tensile force. Moreover, the transverse stress-bearing piece 201 and the longitudinal stress-bearing piece 202 can reduce the attachment area of the adhesive layer 3 and the adhesion force of the adhesive layer 3, so that no adhesive remains, and it is convenient to use.
