A support mechanism includes a fixed body, a rotating unit, a moving unit and a driving unit. The rotating unit is rotationally mounted to the fixed body. The moving unit, disposed at the fixed body, includes a ball screw spline shaft, a ball screw nut and a ball spline nut. The ball screw nut and the ball spline nut are both rotatably disposed at the ball screw spline shaft moved together with the rotating unit. The driving unit, disposed at the fixed body, includes a first driving member and a second driving member to rotate the ball screw nut and the ball spline nut, respectively. With different rotation pairs of the ball screw nut and the ball spline nut to the ball screw spline shaft, the ball screw spline shaft is driven to move, and the ball screw spline shaft is further to move the rotating unit.
