Anti-jamming guide rail of annular motion manipulator

The utility model relates to the technical field of tracks, in particular to an anti-jamming guide rail of an annular motion manipulator, which comprises an annular track and a manipulator moving seat used for driving the manipulator to operate annularly. A first sliding groove is formed in the middle of the inner side wall of the annular rail, second sliding grooves are formed in the top and the bottom of the annular rail, the manipulator moving seat comprises a first sliding block, parallel second sliding seats are arranged at the top and the bottom of the first sliding block, and the two second sliding seats are connected with the first sliding block in a U-shaped mode. The sliding grooves are formed in the top face and the bottom of the annular rail, the multiple sets of sliding blocks are arranged on the mechanical arm moving base, multi-point stress sliding of the mechanical arm moving base is increased, the sliding area is wider, stress is more uniform, and blocking in the sliding process is reduced; a
