When the balloon is deflated, the motor 90 rotates reversely to make the fifth gear 96 rotate reversely, the fifth gear 96 rotates reversely to drive the sixth gear 97 to rotate reversely, the sixth gear 97 rotates reversely to make the gear shaft 100 move forward along the gear shaft sliding groove 98, the gear shaft 100 moves forward to make the sixth gear 97 engage with the fourth gear 94, the sixth gear 97 rotates to drive the fourth gear 94 to rotate, the fourth gear 94 rotates to drive the eighth rotating shaft 85 to rotate, the eighth rotating shaft 85 rotates to drive the second belt pulley 84 to rotate, the second belt pulley 84 rotates to drive the first belt 15 to rotate, the first belt 15 rotates to drive the first rotating shaft 14 to rotate, the first rotating shaft 14 rotates to drive the light rope pulley 18 and the spoke wheel 20 to rotate, the light rope pulley 18 rotates to drive the light rope 19 to retract, the banner wheel 20 rotates to drive the advertisement banner 46 to retract, the light rope 19 and the advertisement banner 46 retract to drive the banner cross bar 45 to move downwards until the balloon is retracted into the banner cavity 47, the balloon descends into the banner cavity 47 to enable the left side air inlet and outlet seat 89 to be in butt joint with the air outlet rod 42, the left side hydraulic rod 86 extends to push the left side pressure rod 32 to rotate, the left side pressure rod 32 rotates to press the left side of the cross bar 40 to enable the left side air inlet and outlet seat 89 to be tightly pressed with the air outlet rod 42, the left side air inlet and outlet seat 89 is tightly pressed with the air outlet rod 42 to enable the air in the flying air ball 31 to be discharged through the air inlet and outlet seat 89, the rack 49 slowly retracts under the action of the support return spring 56, and the upper cover 29 cannot drive the ratchet 26 to reversely rotate due to the reverse rotation of the third rotating shaft 25, after the balloon is deflated, the upper cover 29 needs to be manually covered, the upper cover 29 rotates to drive the third rotating shaft 25 to rotate, the third rotating shaft 25 rotates to enable the rollover prevention mechanism 130 to be completely retracted through reverse transmission of the original transmission route, and the process of retracting the floating balloon is completed.
