The invention provides a three-rocker-arm test device for composite motion microgravity expansion of a spatial mechanism. The three-rocker-arm test device comprises a rocker arm support, a first main shaft support, a second main shaft support, a first rocker arm assembly, a second rocker arm assembly, a third rocker arm assembly, a first main shaft body, a second main shaft body, a double-rotating-shaft assembly and a single-rotating-shaft assembly. The rocker arm support is installed on the truss, the first main shaft supports are installed at the top end and the bottom end of one side of the rocker arm support respectively, the first main shaft body is installed between the two first main shaft supports, the second main shaft supports are installed at the top end and the middle of the other side of the rocker arm support respectively, and the second main shaft body is installed between the two second main shaft supports. The first rocker arm assembly and the second rocker arm assembly are connected to the first spindle body through the double-rotating-shaft assembly, and the third rocker arm assembly is connected to the second spindle body through the single-rotating-shaft assembly. The invention always provides a device which is unfolded in a microgravity environment, and reliably verifies the feasibility of the ground unfolding test of the unfolding mechanism.
