The utility model relates to a coaxially overlapped and multi-layered arbitrary angle rotating limiting device, which belongs to the mechanical equipment technology field. The limiting device comprises a rotating axle, a servo shifting ring, limiting blocking rings and a machine seat; the servo shifting ring, the limiting blocking rings and the machine seat are penetrated through the rotating axle in sequence, the servo shifting ring is fixedly connected with the rotating axle, the limiting blocking rings and the machine seat are sleeved on the rotating axle, the device is provided with at least a blocking ring, the limiting blocking ring close to the machine seat is fixedly connected with the machine seat, and angle rotating limiting devices are respectively arranged between the servo shifting ring and the limiting blocking rings and between adjacent limiting blocking rings; the arbitrary rotating angle of the overall system in one direction can be adjusted through adjusting the numbers of the limiting blocking rings and the rotating angles of the angle rotating limiting devices; therefore, the limiting device has the advantages of simple structure, multi-angled and flexible limiting, convenient operation and extensive adaptation scope.
