a rotating shaft, where the rotating shaft is rotatably disposed in the second housing, the flexible display screen is in rolling contact with the rotating shaft, and the first housing can drive the flexible display screen to move around the rotating shaft. ## Claims ### Claim 1 An electronic device, comprising: a first housing (100); a second housing (200), wherein the second housing (200) is slidably connected to the first housing (100); a first elastic piece (300), wherein a first end of the first elastic piece (300) is connected to the second housing (200); a flexible display screen (400), wherein a first end of the flexible display screen (400) is connected to a second end of the first elastic piece (300), a second end of the flexible display screen (400) is connected to the first housing (100), and the first housing (100) is capable of driving the second end of the flexible display screen (400) to move; and a rotating shaft (500), wherein the rotating shaft (500) is rotatably disposed in the second housing (200), and the flexible display screen (400) is in rolling contact with the rotating shaft (500); wherein in a case that the first housing (100) slides in a direction away from the second housing (200), the first housing (100) drives the flexible display screen (400) to move around the rotating shaft (500), and a part of the flexible display screen (400) moves from a first side to a second side; and in a case that the first housing (100) slides in a direction close to the second housing (200), the first elastic piece (300) drives the flexible display screen (400) to move around the rotating shaft (500), and the part of the flexible display screen (400) moves from the second side to the first side, wherein the first side and the second side are two sides of the rotating shaft (500) that are opposite each other; and the first housing (100) is provided with a first mounting portion (130), and the second housing (200) is provided with a second mounting portion (230), wherein in a case that the first housing (100) detaches from the second housing (200), the first mounting portion (130) is in limiting fit with the second mounting portion (230);
