Antenna posture adjusting device based on three branches two of no -coupling rotate parallel mechanism

Antenna posture adjusting device based on three branches two of no -coupling rotate parallel mechanism is including allocating the platform, moving three branches' motion chains that platform and connection allocated the platform and moved the platform, first branch motion chain includes that the first removal that the platform connected gradually is vice to moving from allocating the platform, second revolute pair I, third remove pair I and fourth universal joint I, second branch motion chain includes and removes vice, second revolute pair II, third and remove pairs II and fourth universal joint II to moving first arc that the platform connected gradually from allocating the platform, third branch motion chain includes first revolute pair and second revolute pair III that the axis intersected vertically, article three, branch motion chain end rotates the axis and is on a parallel with and moves the platform plane, and is parallel to each other. First branch motion chain and second branch motion chain are res
