The invention discloses a parallel vector thruster which comprises a movable platform, a static platform, a propeller driver and two PRS driving branch chains, and the propeller driver is fixed to the movable platform; a PRS motion branch chain is also comprised. The PRS motion branch chain and the two PRS driving branch chains are connected between the movable platform and the static platform in parallel; the PRS motion branch chain comprises a spherical pair connected with the movable platform, a revolute pair connected with the static platform and a connecting shaft connected with the spherical pair and the revolute pair; each PRS driving branch chain comprises a spherical pair connected with the movable platform, a rotating pair connected with the static platform, a lead screw pair connected with the rotating pair and the spherical pair, a waterproof flexible shaft assembly connected with the lead screw pair, and a driving motor driving the waterproof flexible shaft assembly to control the working posture of the movable platform, and a nut of the lead screw pair is fixedly connected with the rotating pair. The two ends of a lead screw of the lead screw pair are connected with the spherical pair and the waterproof flexible shaft assembly respectively, and an output shaft of the driving motor is connected with the waterproof flexible shaft assembly. The thruster is stable in movement and can realize long-distance transmission.
