The invention relates to the technical field of crane trunnions, and discloses a safe and stable crane trunnion which comprises a fixed inner shaft, a first inner cavity is formed in the fixed inner shaft, a fixed inner rod is installed at one end in the first inner cavity, and a sliding disc is installed outside the fixed inner rod. Outer grooves are formed in the upper end and the lower end of the exterior of the fixed inner shaft, fixed screw rods are installed in the outer grooves, sliding rods are installed outside the fixed screw rods, adjusting nuts are installed on the two sides, opposite to the exterior of the fixed screw rods, of the exterior of the sliding rods, and one ends of the sliding rods penetrate through the outer grooves and extend to the exterior of the sliding disc; second inner cavities are formed in the upper side and the lower side of the front end in the fixed inner shaft correspondingly, and pull rods are installed in the second inner cavities. Through movement of the sliding disc and linkage of the transmission structure, stretching and retracting of the pull rod are more convenient, and therefore connection of the fixed inner shaft and the fixed outer shaft is faster.
