[0027] Detailed implementation mode one: Refer to Figures 1 - 3Specifically describe this embodiment. The damping rotary steering wheel used in a flight simulator described in this embodiment specifically includes a handle 1, an upper mounting plate 4, a main shaft 6, a lower mounting plate 13, a damper 15, and a return-to-center structure.

[0028] The turntable is an M-shaped structure; one side edge of the turntable is an M-shaped structure formed by the intersection of two arcs. At the initial position of the main shaft 6, the push rod shaft 22 contacts the turntable under the pulling force of the tension spring 9 and stays at the central depression of the M-shaped arc edge of the turntable; when the handle 1 is rotated, the handle 1 drives the main shaft 6 to rotate, the main shaft 6 drives the turntable to rotate, and the push rod shaft 22 slides on the upper mounting plate 4 and the lower mounting plate 13 under the push of the upper and lower half arc edge structures of the turntable.
