Abstract
A rotating shaft configured to connect two screen-brackets includes two axle structures arranged symmetrically. One of the two axle structures includes an axle, a motion conversion structure, a screen bracket connection structure, and a supporting bracket. The axle includes a worm groove at a surface of the axle. The motion conversion structure cooperates with the worm groove to form a worm drive. The screen bracket connection structure is movably connected to the motion conversion structure and includes mounting holes, which are configured to mount the screen-brackets. The supporting bracket is sleeved at the axle, rotates around an axis of the axle, and is movably connected to the motion conversion structure and the screen bracket connection structure. The motion conversion structure is movable along an axis direction of the axle on a first surface relative to the supporting bracket.
