The invention discloses a one-stop type disassembling process for a small-sized automobile. The one-stop type disassembling process for the small-sized automobile comprises slide rails; the number ofthe slide rails is two; and slide grooves are formed in the tops of the slide rails. According to the one-stop type disassembling process for the small-sized automobile, through coordination of a cutting frame, a cutting device, an adjusting frame, rolling wheel carriers, rolling wheels, a motor, a rotating shaft, a rotating disc, a first electric telescopic rod, a first fixing disc, a treatment box, a compression box, a supporting frame, a second motor, a threaded rod, a threaded sleeve, first hydraulic rods, second fixing discs, a second hydraulic rod, a first extrusion plate, a third hydraulic rod, a second extrusion plate, driving mechanisms, crushing rollers, discharging inclined plates, a screening box, a magnetic separator, a fan, an article storage box and a material fetching device, the problem that the disassembling efficiency of the traditional one-stop type disassembling process for the small-sized automobile is low is solved; and the one-stop type disassembling process forthe small-sized automobile has the advantages that the disassembling is efficient, time and labor are both saved during disassembling, the disassembling effect is good, and the disassembling efficiency is greatly enhanced.
