[0038] See also Figures 7 to 9 In one embodiment, the partition 211 is provided with a mounting groove 2110 . The fixing assembly 22 includes: a central gear 221 , a locking member 222 and a fixing ring 223 .

[0039] Specifically, the central gear 221 is disposed on the partition 221 at one side close to the rotating bracket 23, and is meshed with the transmission member 24. The locking member 222 is disposed in the mounting groove 2110, and a portion of the locking member 222 can extend out of the mounting groove 2110 to cooperate with the central gear 221, thereby locking the central gear 221.
