In particular, as shown in fig. 2, the frame 100 may have a frame structure with sufficient support and a certain installation space, in this embodiment, the frame 100 includes two parallel long side plates 110, which are approximately trapezoidal overall, and are connected by a set of connectors 120, where a mounting plate 130 is fixed to the middle of the top of each long side plate, and bearings (not shown) are coaxially disposed on the two mounting plates 130, and the carrier 200 is connected to the frame 100 by a rotating shaft 210 inserted into the inner holes of the two bearings and can rotate relative to the frame 100, where the rotating shaft 210 may be a long shaft or two coaxial and separated short shafts.
