The invention provides a two-stage floating butt joint type on-orbit replaceable mechanism and a pallet device thereof. The on-orbit replaceable mechanism comprises an outer shell, a cargo carrying assembly, a mechanical active butt joint locking assembly and a two-stage floating electric appliance interface assembly. The two-stage floating electric appliance interface assembly comprises an active butt joint part and a passive butt joint part; the active butt joint part is arranged on the outer shell and a shell of the cargo carrying assembly, the passive butt joint part is arranged on a passive butt joint spacecraft, and the active butt joint part and the passive butt joint part are matched to achieve butt joint of electric appliance interfaces; a butt-joint locking mechanism of the mechanical active butt-joint locking assembly is installed on the outer shell and the cargo carrying assembly, and the mechanical active butt-joint locking assembly drives a lead screw nut structure through a motor to drive a connecting rod structure of the butt-joint locking mechanism to stretch out and draw back, so that butt-joint and locking of the butt-joint locking mechanism and an external device with a locking hole are achieved. The device has the characteristics of high docking precision, high docking rigidity, good carrying stability, convenience in on-orbit operation and the like.
