pushing the connecting rod (6), the first connecting plate (8) and the limiting rod (9) to move downwards along the through groove (3) through the push-pull handle (7), and pushing the steel bars through the limiting rod (9) so that the bending angle of the frame-type steel member is increased; meanwhile, the first gear (12) rotates in the process of meshing with the rack (13), so that the first belt wheel (11), the transmission belt (18) and the second belt wheel (17) rotate; the second belt wheel (17) drives the first rotating shaft (15) and the second gear (16) to rotate;
step four, the third gear (2101) drives the hammering mechanism (21) to rotate in the rotating process of the second gear (16); the second part (2104) of the cam (2102) slides outwards under the action of centrifugal force and periodically hammers the bent part of the frame type steel component until the bent part of the steel component is broken, and the steel component is completely decomposed.
