The universal joint assembly comprises a main shaft, fork rods and a transmission shaft, four connecting shafts distributed in a cross shape are arranged on the outer side of the main shaft in a protruding mode, the two fork rods are fixed to the connecting shafts through bearings, rotating grooves are sequentially formed in the outer sides of the ends, away from the main shaft, of the fork rods, and connecting openings matched with the transmission shaft are formed in the opposite ends of the two fork rods. A limiting inserting hole penetrating through the fork rod and the connecting opening is formed in the outer side of the fork rod, a limiting column matched with the limiting inserting hole is arranged outside the limiting inserting hole, the limiting column penetrates through the transmission shaft, and the outer side of the rotating groove is sleeved with a limiting component extending to the two ends of the limiting column. During assembly, the limiting component is rotated, so that the limiting compon
