In the existing battery fixing device, the stability of the battery cannot be guaranteed, and the battery cannot be replaced after assembly, which affects the use efficiency. When assembling the battery, the batteries need to be separated to prevent friction between the batteries and external collisions from causing damage to the battery and improve safety.
