In some embodiments, the first bearing 6 and the second bearing 7 are respectively arranged at two ends of the planet carrier 31 for supporting, so that the automatic displacement is not easy to occur, and the operation of the inflation movement is stable. The operation process of the inflating movement is as follows: the driver 2 drives the sun gear 33 to rotate, and since the outer ring gear 32 is fixed, each planetary gear in the planetary gear set 34 rotates around its central axis and revolves around the central axis of the sun gear 33, so that the planet carrier 31 also rotates around the central axis of the sun gear 33 as a rotating axis. The carrier 31 transmits power to the piston 5 through the transmission shaft 311 so that the cylinder 4 can be inflated outward.

As shown in fig. 5 and 6, the planet carrier 31 includes a first carrier body 313 and a second carrier body 314 connected to the first carrier body 313, the planetary gear set 34 is located between the first carrier body 313 and the second carrier body 314, and can ensure that the planet carrier 31 and the planetary gear set 34 both stably operate, the second carrier body 314 is provided with a yielding hole 315, the output shaft of the driving member 2 passes through the yielding hole 315 and then is connected to the sun gear 33, the transmission shaft 311 is located at the first carrier body 313, and the connection shaft 312 is located at the second carrier body 314, so as to prevent the second carrier body 314 from obstructing the transmission between the driving member 2 and the sun gear 33.
