Cutting device for steel structure machining

The cutting device for steel structure machining comprises a bottom plate, symmetrical sliding grooves are formed in the upper surface of the bottom plate, symmetrical sliding blocks are connected to the interiors of the two sliding grooves in a sliding mode, supporting plates are fixedly connected to the upper surfaces of the two sets of sliding blocks, and the supporting plates are fixedly connected to the upper surfaces of the two sets of sliding blocks. Supporting seats are fixedly connected to the upper surfaces of the two supporting plates, supporting plates are fixedly connected to the upper surfaces of the two supporting seats, symmetrical first electric push rods are fixedly connected to the upper surface of the bottom plate, and the output ends of the two first electric push rods are fixedly connected with the side faces, away from each other, of the two supporting plates correspondingly. According to the device, through cooperation of sliding grooves and sliding blocks, supporting plates can move m
