High-strength high-precision lightweight constant-speed sliding end universal joint

The utility model relates to the technical field of universal joints, in particular to a high-strength high-precision light-weight constant-speed sliding end universal joint which comprises a universal joint body, and the universal joint body comprises a shell besides-star wheel. A star-shaped sleeve which is sleeved with the connecting shaft in a hollow mode is arranged in the shell besides-star wheel, the star-shaped sleeve slides at a constant speed along the interior of the shell besides-star wheel, the connecting shaft is sleeved with a reset piece which is connected with the shell besides-star wheel and is in an elastic return mode in a hollow mode, and the connecting shaft buffers the constant-speed sliding of the star-shaped sleeve through the reset piece. Through the matching arrangement of the connecting shaft and the reset piece, the structure can improve the connecting strength of the connecting shaft through the reset piece, so that the slippage amount of the starlike sleeve can be limited to a c
