The invention relates to the field of space exploration, in particular to a single-driving multiple-output lifting mechanism. A driving device, a driving gear transmission device and a plurality of trapezoidal thread devices are installed on a base plate. A center transmission gear is installed on the base plate in a rotating mode and is further connected with the driving gear transmission device.The driving device drives the center transmission gear to rotate through the driving gear transmission device. The multiple trapezoidal thread devices are arranged around the center transmission gearand further comprise trapezoidal lead screws and trapezoidal nuts. The trapezoidal nuts are installed on the base plate in a rotating mode. One ends of the trapezoidal nuts are connected with outputgears, and the other ends of the trapezoidal nuts are in threaded connection with the trapezoidal lead screws. All the output gears are in engaged transmission with the center transmission gear. According to the single-driving-source multiple-output lifting mechanism provided by the invention, control is easy, the structure is compact, bearing capacity is high, synchronism is made higher, and thesingle-driving multiple-output lifting mechanism is suitable for the occasions with installation space being limited and multi-point output being required.
