A clamping apparatus for clamping and transporting secondary batteries, characterized in that, the clamping apparatus comprises: a base; a support plate, stacked with the base in a vertical direction; a locking assembly, by which the support plate is connected to the base, wherein the locking assembly comprises a first locking member disposed on the support plate and a second locking member disposed on the base, the support plate is movable in the vertical direction and is capable of being connected to or separated from the base by connection of the first locking member to the second locking member or separation of the first locking member from the second locking member, and a horizontal load is able to be transmitted between the support plate and the base via the first locking member and the second locking member locked to each other; a clamping assembly disposed on a surface of the support plate facing away from the base, and comprising a first clamping jaw and a second clamping jaw spaced apart in a first horizontal direction, wherein the first clamping jaw is connected to the support plate in a horizontally movable manner and is capable of moving toward or away from the second clamping jaw to switch between a clamping position and an opening position, wherein the clamping assembly is adapted to hold the secondary batteries between the first clamping jaw and the second clamping jaw; a clutch mechanism and a drive mechanism, wherein the drive mechanism is connected to the first clamping jaw via the clutch mechanism, and the clutch mechanism can transmit or disconnect a power generated by the drive mechanism, such that a power of the drive mechanism is transmitted or stopped from being transmitted to the first clamping jaw by the clutch mechanism, wherein the drive mechanism comprises a connector disposed below the base and a telescopic element connected to the connector, and the clutch mechanism comprises a first insertion portion disposed on the telescopic element and a second insertion portion disposed on the first clamping jaw, wherein the first insertion portion and the second insertion portion are capable of being connected together in an insertion manner or separated from each other in the vertical direction; and a telescopic energy storage mechanism disposed on the support plate, wherein the telescopic energy storage mechanism is connected to the first clamping jaw and is capable of applying a thrust force toward the second clamping jaw to the first clamping jaw when the first clamping jaw is switched from the opening position to the clamping position, and each of two opposite edges of the support plate that extend over the base is adapted to form one vertical lifting portion. a base;
