Embodiments of this application provide a foldable electronic device, including: a shaft cap, a body, a first cam component, and a second cam component. The first cam component and the second cam component come into pressure contact. The first cam component is configured to be rotatable around a central shaft of the first cam component. The second cam component is configured to be slidable along a direction of the central shaft. A contact surface of the first cam component and the second cam component includes a locking section, an angle between a normal direction of the locking section and the central shaft is less than or equal to a preset value, and a resultant force of a cam driving member in a rotation direction of the cam driving member is o, so that the body is not automatically unfolded or folded, thereby implementing the freestop characteristic.
