[0024] Specifically, the support assembly 11 includes a protective sleeve 111, the bottom of the protective sleeve 111 is fixedly connected to a support plate 112, the bottom of the support plate 112 is fixedly connected to a plurality of mounting blocks 113 in a circular array, a group of first limiting shafts 114 are fixedly connected to one side of the plurality of mounting blocks 113 close to the bottom, a group of second limiting shafts 115 are fixedly connected to the other side of the plurality of mounting blocks 113 close to the bottom, and a driven gear 116 is fixedly connected to the outside of the protective sleeve 111 away from the support plate 112.
