Abstract:
A rotating shaft apparatus and an electronic device. The rotating shaft apparatus comprises a first rotating mechanism (10) and a second rotating mechanism (30). The first rotating mechanism comprises a first ratchet (12) and a first tooth (14) engaged with the first ratchet. The first tooth can rotate with respect to the first ratchet in a first rotation direction. The engagement structure between the first tooth and the first ratchet makes the first tooth stop rotating with respect to the first ratchet in a second rotation direction, wherein the second rotation direction is opposite to the first rotation direction. The second rotating mechanism is disposed coaxially with the first rotating mechanism, and comprises a second ratchet (32) and a second tooth (34) engaged with the second ratchet. The second ratchet is in rotation stop connection with the first tooth. The second tooth can rotate with respect to the second ratchet along the second rotation direction. The engagement structure between the second tooth and the second ratchet makes the second tooth stop rotating with respect to the second ratchet in the first rotation direction. The rotating shaft apparatus can implement in-place maintenance at a plurality of angles in a rotation direction, and the engagement structure is not easy to wear and implements stable engagement.
