Preferably, an inclined main cutting edge is arranged at the edge of the lower side of the upper cutter, and the limiting barrier strip is positioned at the lower end of the main cutting edge of the upper cutter. The limiting barrier strips limit the upper cutter on one hand, and limit one side of the water adhesive tape on the other hand to prevent the water adhesive tape from deviating.

Preferably, both ends of the upper cutter holder are provided with connecting holes, the upper end of the cutter support is provided with a rotating shaft penetrating through the connecting holes, and the connecting holes are rotatably connected with the rotating shaft.

Therefore, the water-stop adhesive tape cutting device has the advantages of being compact and stable in structure and capable of smoothly cutting off the water-stop adhesive tape.
