Moreover, the adjustable distance between the cutting knives 5 can also make the cutting device suitable for cutting iron sheets of different sizes. The first bidirectional threaded rod 9 is driven to rotate by the first motor 10, and the adjusting plate 6 drives the adjusting slot 7 to slide under the limiting action of the mounting seat 2. At the same time, the second motor 12 is started to drive the second bidirectional threaded rod 11 to rotate, and the adjusting slot 7 pushes the adjusting rod 20 to drive the cutting knife 5 to slide.
