FIG. 1 is a general schematic view of the present invention;

FIG. 2 is a schematic view of the utility model after being torn integrally;

fig. 3 is a schematic view of the present invention taken apart as a whole.

In the figure: 1-substrate, 2-first release layer, 3-second release layer, 4-kneading sheet, 5-connecting sheet, 6-groove, 7-convex tooth, 8-first bonding layer and 9-second bonding layer.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1 to 3, an easy-to-tear double-sided adhesive tape structure comprises a substrate 1, a second adhesive layer 9 is arranged at the lower end of the substrate 1, first adhesive layers 8 are uniformly arranged on the front side and the rear side of the upper end of the substrate 1, first release layers 2 are bonded to the upper ends of the first adhesive layers 8, second release layers 3 are connected between the first release layers 2, a connecting sheet 5 is connected to the left end of each second release layer 3, the front end and the rear end of the connecting sheet 5 are respectively connected with the first release layers 2, a pinching sheet 4 is connected to the right end of each second release layer 3, the left end of each pinching sheet 4 is attached to the first release layer 2, the lower ends of the second release layers 3, the pinching sheets 4 and the connecting sheet 5 are attached to the substrate 1, tear lines are arranged between the second release layers 3 and the first release layers 2, the first adhesive layers 8 and the second adhesive layers 9, and the first adhesive layers 8 and the second adhesive layers 9 are, the first release layer 2, the second release layer 3, the kneading sheet 4 and the connecting sheet 5 are release paper, the first bonding layer 8 and the first release layer 2 are equal in length, the length of the first adhesive layer 8 is shorter than that of the base material 1, the width of the pinch sheet 4 is equal to the length difference between the base material 1 and the first adhesive layer 8, and by pinching the pinch sheet 4, then the first release layer 2 is pressed to tear the second release layer 3, so that the second release layer 3 is torn from the space between the first release layer 2 along the tearing line, and the second release layer 3, the pinching piece 4 and the connecting piece 5 are not stuck by the first bonding layer 8, so that when the second release layer 3 is torn to the connecting piece 5, the first release layer 2 is loosened, can tear around through connection piece 5 around two from type layer 2 from tie coat 8 and tear, just so can the tie coat 8 bond article to be convenient for tear and tear from type layer 2 and from type layer two 3.
