Bending machine

A bending machine comprises a handle, a piece of short angle iron, a piece of long angle iron, a piece of folded plate angle iron, two hinges and two bolts, and all components of the bending machine are made of steel. The two hinges are fixedly connected to the two ends of the short angle iron and the two ends of the long angle iron so that the short angle iron and the long angle iron can be connected, and the short angle iron can turn over along hinge shafts in the middles of the hinges. The folding plate angle iron is connected with the long angle iron through bolts, the folding plate angleiron is located between the two hinges, the folding plate angle iron is reversely buckled on the long angle iron, gaps are reserved between the edges of the folding plate angle iron and the long angleiron, and the sizes of the gaps between the folding plate angle iron and the long angle iron can be adjusted by loosening and tightening nuts on the bolts. Through the turning and extruding principleof the hinge, bending of t
