[0087] The present invention adjusts the turntable's various postures in three-dimensional space by providing three independently driven posture adjustment mechanisms, thereby enabling performance testing of a structural component mounted on the turntable in various postures. Specifically, the turntable's various spatial postures are adjusted by adjusting the relative positions of the three posture adjustment mechanisms. This not only meets various spatial posture requirements, but also prevents jamming through the provision of a ball-jointed motion mechanism and effectively connects the three posture adjustment mechanisms when there are height differences between them. After the posture is adjusted to the desired position, the adjustment drive can be used to lock the posture adjustment mechanisms, thereby locking the turntable's position and posture.
