A connection assembly comprises a bracket, a linkage element, a first elastic element, a trigger element, and a second elastic element. The first elastic element is connected with the bracket and the linkage element. One end of the trigger element is fixed on the bracket. The second elastic element is connected to the trigger element and the bracket. When the electronic apparatus is not connected to the dock, the linkage element is located at a first position of the trigger element, and the first elastic element stores a first elastic force. When the electronic apparatus is connected to the dock, the trigger element receives an external force so that the second elastic element stores a second elastic force, and the first elastic element releases the first elastic force to move the linkage element to a second position of the trigger element.
