The first driving cylinder 2 is located on one side of the second driving cylinder 8. The output ends of the first driving cylinder 2 and the second driving cylinder 8 are both fixedly connected to a blade body 15 through a telescopic push rod 1. Buffer stabilizing mechanisms are installed at both ends of the blade body 15.

The blade body 15 slides vertically along the surfaces of the fixed sliding column 13 and the buffer guide column 11 via the sliding block 10. The buffer spring 12 is installed and fixed on the outer surface of the buffer guide column 11. By designing a sliding protection for both ends of the blade body 15 and providing a buffer stabilization mechanism, the sliding block 10 can drive the blade body 15 to slide stably along the surfaces of the fixed sliding column 13 and the buffer guide column 11. When the blade body 15 is performing downward cutting operations, the buffer guide column 11 and the buffer spring 12 provide a good buffer protection effect, further improving the safety and stability of the blade body 15 during cutting operations.

[0022] Furthermore, an installation plate 5 is welded and fixed to the upper end of the paper cutting frame 9. A drive air pump 7 is installed on the front surface of the installation plate 5. The output end of the drive air pump 7 is sealed to the first drive cylinder 2 and the second drive cylinder 8 through the air guide pipe 3. Both ends of the air guide pipe 3 are provided with sealing joints 4. The drive air pump 7 is turned on to drive and control the first drive cylinder 2 and the second drive cylinder 8 to operate. The sealing joints 4 can provide a good sealing protection effect at the connection part of the air guide pipe 3, preventing gas leakage and cylinder failure.
