Abstract: The present disclosure relates to an anti-falling mechanism for preventing an electronic component installed inside a casing from falling rapidly. The anti-falling mechanism includes at least one damping gear and at least one gear rack. The at least one damping gear is disposed on the electronic component. The at least one gear rack is disposed at a position corresponding to the at least one damping gear.
