Adhesive tape coating and positioning pasting tool and adhesive tape coating and positioning pasting method

The invention discloses an adhesive tape coating and a positioning pasting tool. A cavity consistent with a pasting positioning plate in shape is formed in the top end face of a tool base, and a limiting step is formed on the edge of the top of the cavity in the circumferential direction. A narrow adhesive tape through groove is formed in the pasting positioning plate, the two sides of the front face of the narrow adhesive tape through groove expand outwards to form a wide adhesive tape groove, the narrow adhesive tape through groove and the wide adhesive tape groove share a same center line and are equal in length, and operation holes are formed in the two ends of the narrow adhesive tape through groove. Repeat use can be achieved, operation is convenient, rapid and reliable, the principle is simple, cost waste is reduced, and popularization and use are convenient. The invention further discloses a method. The method comprises the steps that the front face of the pasting positioning plate is positioned on th
