Patent ID: 8550925

Claim:
A universal joint, comprising: a first rotating assembly, comprising: a rotating member comprising a main body and a pair of rotating portions extending from opposite ends of the main body; a pivotal member rotatably connected to the pair of the rotating portions, the pivotal member comprising a base body and a pair of pivotal portions extending outwardly from opposite ends of the base body, wherein each pivotal portion is substantially a stepped shaft and extends coaxially from the base body, each pivotal portion comprises a resisting end connected to the base body, and a shaft end connected to the resisting end, each shaft end is rotatably connected to one of the pair of rotating portions, correspondingly, a diameter of the shaft end is less than that of the resisting end, each pivotal portion axially defines a mounting hole therein extending through the shaft end and the resisting end; and a pair of locking members respectively engages with opposite ends of the pivotal member to prevent the pivotal member detaching from the rotating member, the pair of locking members engaging with the pair of mounting holes of the pivotal member to rotatably connect the pivotal member to the pair of rotating portions of the rotating member; a second rotating assembly being the same as the first rotating assembly; and a linking member extending into the pivotal member of the first rotating assembly and engaging with the pivotal member of the second rotating assembly to connect the two pivotal members together.
