The invention discloses an automatic retracting and releasing trolley for a floating balloon advertisement banner. The trolley comprises a box body, wherein a side cavity, a banner cavity and a transmission cavity are formed in the box body; a balloon inflating and deflating mechanism and an advertisement banner retracting and releasing mechanism are arranged in the banner cavity; the trolley is simple in structure and easy and convenient to operate, hydrogen with certain danger, which is frequently used by the floating air ball, is replaced by a nitrogen cylinder for inflating; retracting andreleasing of the floating air ball are automatically controlled through forward and reverse rotation of the motor, manual operation is not needed, nitrogen in the balloon can be directly exhausted into the atmosphere during deflation, safety and harmlessness are achieved, meanwhile, the floating balloon can move in the using process, the potential safety hazard that the device may roll over whenthe floating balloon suddenly encounters strong wind is effectively prevented through the anti-overturning mechanism, the high integration degree is achieved, and the balloon retracting and releasingefficiency is effectively improved.
