The invention discloses a low-temperature rotation connector. The low-temperature rotation connector comprises a rotation connector body. The rotation connector body comprises an outer ring and an inner ring which are connected through a roller path ball bearing structure. A first flange is arranged at a lower port of the outer ring, and a second flange is arranged at an upper port of the inner ring. The low-temperature rotation connector further comprises hydraulic drive devices, first connecting devices and second connecting devices. One end of each first connecting device is fixedly connected with the outer ring, and the other end of each first connecting device is connected with a cylinder body of the corresponding hydraulic drive device. One end of each second connecting device is fixedly connected with the inner ring, and the other end of each second connecting device is connected with a piston rod of the corresponding hydraulic drive device. The hydraulic drive devices are used for driving the outer ri
