Hardware waste collection device

The invention relates to the technical field of waste collection, and discloses a hardware waste collection device which comprises a machine body and a rack, wherein the bottom of the rack is fixedly connected to the rear portion of the top of the machine body, a machining cutter is fixedly connected to the upper surface of the rack, and a fixed supporting rod is fixedly connected to the front portion of the top of the machine body. By arranging a waste cutter, a large gear, a small gear, a longitudinal toothed bar I and a vertical toothed bar, a pressing plate at the top of a machined part is used for pressing and fixing the machined part, a sliding structure at the top of a supporting stand column slides downwards along with the machined part under the action of gravity; and meanwhile, the vertical toothed bar is driven to vertically slide downwards, and the small gear and the large gear are driven to rotate anticlockwise; the large gear rotates to enable the two longitudinal toothed bars I to oppositely mo
