The cam 13 is fixedly installed on the drive rod 12, and the protruding end of the cam 13 is overlapped on the top side of the base frame 7. When the protruding part of the cam 13 rotates and abuts on the base frame 7, the bottom The frame 7 generates a downward force, which indirectly realizes the downward movement of the two upper clamping seats 6; a mounting frame 14 is fixedly installed on the top side of the cutting frame body 1, and a cutting mechanism is arranged in the mounting frame 14, and the cutting mechanism includes a hydraulic rod 15 and a cutting blade 16.
