Three freedom degree reflector adjusting apparatus

The invention discloses a three-degree-of-freedom reflector adjusting device, which can achieve inclination and pitch adjustment of a reflector by using the multi-degree-of-freedom work principle of gimbal and achieve linear displacement adjustment of another degree of freedom by controlling the distance between an adjusting pedestal and a reflector frame. The adjusting device comprises the reflector frame and the adjusting pedestal, wherein the a reflector is arranged on one side of the reflector frame; the other side of the reflector frame is opposite to the adjusting pedestal; a linear displacement adjuster connected with the reflector frame and the adjusting pedestal, the linear displacement adjuster is universally connected with the side of the reflector frame opposite to the adjusting pedestal at one end and is axially connected with the adjusting pedestal at the other end; and the connection position of the linear displacement adjuster and the reflector frame corresponds to the geometric center of the reflector.
