Abstract
A rotation shaft assembly includes first and second rotation shafts configured to be connected to first and second bodies, respectively, a synchronization mechanism disposed between and transmissively connected to the first and second rotation shafts, and a control mechanism including first and second followers sleeved at the first and second rotation shaft, respectively, and a lock member disposed between the first and second rotation shafts. In a first state of the first and second bodies flipping relative to each other, the lock member interacts with the first or second follower to fix the first or second rotation shaft. In a second state of the first and second bodies flipping relative to each other, action of the lock member on the first and second followers is released, and the first and second rotation shafts rotate synchronously through the synchronization mechanism.
