A base board floating arm configured to carry a base board and comprising:

• a fixing base;
• at least one carrier board configured to carry the base board;
• each one of the at least one carrier board having:
• a connecting section and a buckling section respectively disposed at two ends of the carrier board;
• the connecting section connected to the fixing base;
• a carrier section connecting the connecting section and the buckling section, and an airflow channel formed in the carrier section;
• a carrier surface including a surface of the carrier board which faces upward, and the carrier surface configured to carry the base board;
• multiple airflow outlets formed on the carrier surface, the airflow outlets fluidly communicating with the airflow channel;
• at least one buckling set mounted at the buckling section of the carrier board, each one of the at least one buckling set having:
• a buckling unit movably mounted at the buckling section, and the buckling unit and the carrier board configured to selectively fix the base board.
