[0048] Further, if Figures 1-3 As shown, in this embodiment, the rotating assembly includes: a spline screw 421, four spline nuts 422 and four rotating shafts 423.

The second drive assembly is disposed on the second bearing seat 3 and is connected to the extended end of the spline screw 421. The first drive assembly is used to drive the first screw nut 411 and the second screw nut 412 to rotate. The second drive assembly is used to drive the spline screw 421 to rotate.

[0052] Further, if Figures 1-4 As shown, in this embodiment, the first drive assembly includes: a first motor 511, a first driving pulley 512, a first synchronous pulley 513, a second synchronous pulley 514, and a first belt (not shown).
