A connecting rod of a boat paddle, comprising:

• a deflation apparatus disposed at a connecting portion of the connecting rod, wherein the connection portion is configured to connect a pulp board;
• wherein the deflation apparatus further comprises:
• a cylindrical deflation main body including a socket portion and an exhausting portion sequentially arranged along a longitudinal axis of the cylindrical deflation main body, wherein the socket portion includes an opening for receiving a spool of a valve and the opening is connected to an inner space, wherein the inner space extends through the socket portion and the exhausting portion, and an outer wall of the exhausting portion includes a plurality of exhausting holes connected to the inner space, wherein an exhausting direction of the plurality of exhausting holes is orthogonal to the longitudinal axis of the cylindrical deflation main body;
• and
• a flat stream leading portion disposed in the inner space and configured to separate the inner space to form at least two exhausting channels extended along the longitudinal axis of the cylindrical deflation main body, wherein each of the at least two exhausting channels is connected to at least one of the plurality of exhausting holes;
• wherein the flat stream leading portion has an abut side, wherein the abut side is extended toward the opening and abuts the spool of the valve.
