A clamping apparatus includes a carrier portion formed on a regularly shaped panel, where a track slot is formed in a length direction in the carrier portion; a movable unit, mounted at an end of the carrier portion and capable of being separated from the carrier portion along a length direction of the track slot; and a clamping unit, mounted on a movable unit and configured to prevent, in at least four directions, a clamped object from being separated from the carrier portion. The problem that a size range of clamped objects applicable to the clamping apparatus is limited. The clamping unit is configured to prevent, in the at least four directions, the clamped object from being separated from the carrier portion, effectively preventing the clamped object from being separated from the carrier portion and allowing the clamped object to be protected even in a complex environment.
