The worm 33 is meshed with the turbine 32; in this embodiment, the connection method of the shaft 34, the turbine 32, and the worm 33 is as follows Figure 5 As shown, when in use, the first servo motor 31 is started to drive the worm 33 to rotate, and the turbine 32 engaged therewith rotates, thereby driving the rotating platform 2 to rotate.

[0025] like Figure 4 、 Figure 6 、 Figure 7 As shown, the fixing assembly includes a fixing seat 41, a second servo motor 42, a driving wheel 43, a fixing rod 44 and three driven wheels 45; the interior of the rotating table 2 is fixedly connected to the fixing seat 41, the fixing seat 41 is a hollow structure, the bottom of the fixing seat 41 is fixedly installed with the second servo motor 42, the output end of the second servo motor 42 passes through the bottom wall of the fixing seat 41 and extends to the interior of the fixing seat 41 and is connected to the driving wheel 43, the interior of the fixing seat 41 is rotatably connected to the three driven wheels 45, the three driven wheels 45 are all meshed with the driving wheel 43, and the tops of the three driven wheels 45 are fixedly connected to the driving wheel 43.
