[0031] The working principle and use process of the utility model are as follows:

[0032] When paper products need to be cut, the operator first adjusts the position of the limiting component 5 according to the required cutting length by loosening the positioning bolt 503. Then, the position of the limiting plate 501 is adjusted, and the positioning bolt 503 is tightened after the position of the limiting plate 501 is adjusted. Next, the paper product to be cut is placed above the support platform 1, with one end of the paper product resting against the right side of the limiting plate 501. Then, the control switch of the electric telescopic rod 408 is activated. The electric telescopic rod 408 drives the support plate 409 to move vertically upwards. At this time, the support plate 409 will press the right end of the rotating plate 303 upwards, while the left end of the rotating plate 303 will rotate downwards. The strip-shaped top plate 206 is compressed, causing the cutting blade 205 to move vertically downwards, thereby completing the cutting of the paper product. Since the fixed support 302 is located on the left side of the rotating plate 303, according to the lever principle, the electric telescopic rod 408 can achieve the cutting of the paper product by the cutting blade 205 without using a large force. In addition, when the electric telescopic rod 408 cannot work, the drive motor 406 is started. The drive motor 406 drives the threaded screw 405 to rotate, thereby causing the moving slider 407, the electric telescopic rod 408 and the support plate 409 to move backwards, thereby causing the support plate 409 to disengage from the right end of the rotating plate 303. At this time, cutting can also be achieved by manually driving the right end of the rotating plate 303.
