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 ring and the inner ring to relatively rotate through the relative movement of the cylinder bodies and the piston rods. The low-temperature rotation connector has the beneficial effects of being simple in structure, good in sealing effect, high in anti-freezing capability and convenient and flexible to use, an initiative driving rotation function and a passive following rotation function can be achieved, and the purpose of accurate control can be achieved in an initiative driving rotation manner.
