[0045] like Figure 3 As shown, a three-axis G-force simulator provided by the present invention is provided, wherein the driving assembly 5 includes a No. 1 motor 51 and a gear transmission pair 52 , wherein the No. 1 motor 51 is fixedly connected to the No. 2 sliding seat 10 , and a gear transmission pair 52 is arranged between the output shaft of the No. 1 motor 51 and the horizontal rotating seat 12 .

At the same time, the push rod 68 pushes the rotating handle 67 to rotate, and the rotating handle 67 extends to the outside of the support frame 61, so as to facilitate the hand to grasp the rotating handle 67 and increase the supporting force of the body.
