When the traditional lifting structure is not lifting, the lifting device will interfere with the battery pack, reducing the application space of the battery pack. During lifting, there is a safety hazard due to the insufficient strength of the fixing screws of the fixed lifting device. This results in a small installation space for the battery pack box, slow installation and replacement, and a waste of manpower, material and financial resources. Summary of the Invention
