[0022] In some embodiments, the rotating member 2 includes a first fixed ear seat 21 and a second fixed ear seat 22, and a rotating block 23 is hinged between the first fixed ear seat 21 and the second fixed ear seat 22.

[0023] In some embodiments, the rotating frame 3 includes a square fixed block 31, and a fixed cylinder 32 is provided on one side of the fixed block 31. The fixed block 31 is used to support and fix the fixed cylinder 32. A bracket body 4 is sleeved on the fixed cylinder 32, so that the bracket body 4 is rotatably connected to the fixed cylinder 32. The rotational connection is a prior art and will not be repeated here. It can realize the smooth rotation movement of the bracket body 4 on the rotating frame 3.
[0024] In some embodiments, the rotation drive unit 5 includes a fixed sleeve 51, a fixed plate 52, a rotating motor 53, a crank 54 and a driving rod 55. The fixed sleeve 51 is sleeved on the base 1, and a fixed plate 52 is provided on one side of the fixed sleeve 51. Two rotating motors 53 are symmetrically mounted on the fixed plate 52.

A crank 54 is provided on its output shaft, and the two ends of the driving rod 55 are respectively hinged to the crank 54 and the rotating frame 3. When the rotating motor 53 is started, the crank 54 rotates and drives the rotating frame 3 to rotate through the driving rod 55.

[0027] In some embodiments, a control system is also included, and the control system is electrically connected to the drive system. The control system may include receiving a motion signal and then controlling the drive system to perform corresponding movement according to the signal, thereby achieving precise control of the motion bracket.
[0028] The specific working principle is as follows:
[0029] When the three-axis motion bracket of the present invention is used, firstly, the control system controls the driving system to perform corresponding motion according to the signal.
[0030] The rotation motor 53 of the rotation drive unit 5 is controlled to start, the crank 54 is driven to rotate, and then the rotating frame 3 is driven to rotate through the driving rod 55. When the rotating frame 3 needs to rotate forward and backward, the two rotation motors 53 are controlled to drive synchronously, and when the rotating frame 3 needs to rotate left and right, the two rotation motors 53 are controlled to drive asynchronously. The rotation motor 61 of the rotation drive unit 6 is controlled to start, the rotating plate 62 is driven to rotate, and then the rotating ring 63 and the bracket body 4 are pulled to rotate through the connecting rod 64, so that the bracket body 4 can rotate on the plane.
