[0069] In one embodiment, a waste box with an open top is provided on one side of the first clamping assembly close to the second clamping assembly. After the cutting assembly cuts the tape, the second jaw is loosened so that the wound tape automatically falls into the waste box.

[0070] Through the cooperation of the second jaw and the waste box, the storage of the cut and wound tape is realized, avoiding the tape from being scattered in the working environment and helping to keep the inside of the mechanism clean.
