As shown in fig. 2, in the present embodiment, a cutting blade 100 for adhesive tape is provided, which has a blade body 110, and a plurality of cutting teeth 120 are formed on one side D of the blade body 110.
As shown in fig. 2, each cutting tooth 120 protrudes from a side edge D of the blade body 110. The protrusion distance of the cutting tooth 120 protruding from the side edge D of the blade body 110 is defined as H, and H is 0.5mm to 1.5 mm.
As shown in fig. 2, each of the cutting teeth 120 has a cutting portion 121 for cutting the adhesive tape. The cutting part 121 has a length of 1mm to 2mm and is parallel to the side edge D of the blade. And, a spacing between two adjacent cutting teeth 120 is defined as S, which is a distance between adjacent end points of the cutting portions 121 of two adjacent cutting teeth 120, as shown in fig. 2. The range of the spacing S is 1.5 mm-3.5 mm.
