The invention discloses a propeller arm connection assembly. Propeller arms are installed on a machine body of an aircraft. Each propeller arm comprises a propeller arm first segment and a propeller arm second segment. The propeller arm connection assembly comprises a first connecting base and a second connecting base fixedly connected with the first connecting base in a butting mode through electric connectors. The first connecting base is connected with the propeller arm first segments, and the second connecting base is connected with the propeller arm second segments. At least one of the first connecting base and the second connecting base is in non-fixed limiting connection with the corresponding propeller arm first segment or the corresponding propeller arm second segment. According to the propeller arm connection assembly, one connecting base can swing together with the other connecting base which joggles under the condition that the propeller arm segments provided with paddles joggle; deformation of the electric connectors is reduced or avoided; and therefore poor contact in the subsequent connection process is avoided, and stability and safety of the aircraft are greatly improved.
