The invention discloses a vector propeller of a two-degree-of-freedom parallel mechanism, and relates to the technical field of vector propellers. The device comprises a lower platform, the lower platform is fixedly connected with a first base, the first base is provided with a first driving rod through a moving pair, one end of the first driving rod is rotatably connected with a first connecting rod, and one end of the first connecting rod is in spherical hinge connection with an upper platform; and the second base is fixedly connected to the lower platform, and a second driving rod is installed on the second base through a moving pair. The two-degree-of-freedom parallel mechanism is designed, transverse rolling and pitching of the upper platform are achieved, vector thrust is provided for the AUV, after the upper platform is connected with a propeller of the AUV in series, the operation range in the dominant direction can be effectively widened, rudder angle lifting of the propeller can be accurately adjusted, the purpose of efficient operation under the special environment is achieved, the structure is simple and reliable, and operation is convenient. The invention has the advantages of low manufacturing cost, high speed, low cost, light weight and the like.
