This application provides a rotating shaft connection mechanism. The rotating shaft connection mechanism includes two rotating shafts, two connection assemblies corresponding to the two rotating shafts, and one synchronous driving block, where each connection assembly includes a slide rail block and a drive sheet, a boss of the slide rail block is inserted into a slanting groove on the drive sheet, the synchronous driving block is connected to the two rotating shafts, and the synchronous driving block is disposed on two sides of a connecting piece on the drive sheet by using provided connecting pieces, and is inserted into a spiral groove by using a provided positioning protrusion part. In this way, through fitting connection between the two rotating shafts, the one synchronous driving block and the slide rail blocks and drive sheets of the two connection assemblies corresponding to the two rotating shafts, rotation of the rotating shaft is converted into sliding of the slide rail block. When the rotating shaft connection mechanism is disposed on a device with a flexible screen, the device is enabled to slide in a direction towards the rotating shaft or away from the rotating shaft, thereby effectively ensuring that a length of the flexible screen remains unchanged during folding or unfolding of the flexible screen.
