[0034] Adopting the above solution: By setting the lower end of the cutter head 432 to be serrated, it has the function of more easily rubbing and breaking the tape 1 when pressing down the cutter head 432 for shearing.

[0035] The working principle of the present utility model:

[0036] During use, the tension spring 414 will pull the pressing plate 413 downward, and the pressing plate 413 moves downward on the surface of the moving rod 412. According to the thickness of the tape 1 on the reel 2, the surface of the roller 423 is always kept in pressing contact with the upper surface of the tape 1. When the tape 1 is pulled out of the reel 2 and rotates on the fixed shaft 3, the roller 423 will also be driven to rotate on the surface of the rotating shaft 422, and rotate in cooperation with pulling out the tape 1. When the pulled tape 1 needs to be cut off during use, by pressing the top plate 433 downward, the top plate 433 moves downward on the surface of the slide bar 4341, compresses the spring 4342, and at the same time drives the slide plate 431 to move downward. The downward movement of the slide plate 431 drives the cutter head 432 to move downward to cut off the tape 1, and then release the top plate 433, and the spring 4342 will rebound, push the top plate 433 upward, and the top plate 433 drives the cutter head 432 to move upward and reset through the slide plate 431, thereby completing the cutting.

[0037] In summary, for the tape with a shearing structure, by the combined use of the tape 1, the reel 2, the fixed shaft 3, the auxiliary cutting device 4, the pressing component 41, the support plate 411, the moving rod 412, the pressing plate 413, the tension spring 414, the rolling component 42, the support seat 421, the rotating shaft 422, the roller 423, the cutting component 43, the sliding plate 431, the cutter head 432, the top plate 433, the reset component 434, the sliding rod 4341, the spring 4342, the limiting plate 4343 and the threaded sleeve 5, it solves the problem that in the daily use of the existing tape, usually the tape pulled out needs to be cut according to the length required for use, but it is very difficult to cut the tape only by manual tearing, thus affecting the convenience of use and resulting in more trouble and lower efficiency in use.
