Electronic device

An electronic device, comprising:

• a shell;
• a rotating frame rotatably provided outside a part of the shell, wherein the rotating frame is configured to rotate to at least two gears relative to the shell;
• in response to that the rotating frame rotates to any one of the gears, the rotating frame is snap-fitted with the shell for positioning through a gear limit mechanism;
• and in response to that the rotating frame is rotated out of the gears by an external force, the rotating frame is released from the shell;
• a guide limit mechanism comprising a guide limit groove and a guide limit protrusion slidably provided in the guide limit groove, wherein one of the guide limit groove and the guide limit protrusion is relatively fixed to the shell, and the other of the guide limit groove and the guide limit protrusion is provided on the rotating frame to limit a rotation range of the rotating frame;
• and
• a sensor and a controller, wherein the sensor is configured to sense a current rotation gear of the rotating frame;
• the sensor is connected to the controller, and the controller is configured to control and perform a corresponding function according to the current rotation gear.
