When the cutting die 7 needs to be replaced, the rotating handle 6 is rotated to drive the threaded rod 20 and the active bevel gear 12 to rotate, and at the same time drive the driven bevel gear 13 meshing therewith to rotate, and then drive the rotating rod 14 to rotate. At this time, the insert rod 16 slides backward in the slide groove 15, and the insert rod 16 moves away from the slot 19, releasing the fixed limit of the card block 17, and the cutting die 7 can be removed for replacement. When the cutting die 7 is reinstalled, the card block 17 is inserted into the card slot 18, the threaded rod 20 is rotated in the opposite direction, and the insert rod 16 is reinserted into the slot 19, and the card block 17 is fixed and limited, that is, the installation of the cutting die 7 is completed.
