I have plotted separately two graphics, and I cannot use show to combine them together because this would disturb the moving pattern. I don't know How to do this. By the way, how to draw another ball rotating the opposite direction in the same picture so that there are two oppositely rotating balls?

Graphics3D[{Sphere[{0, 0, 0}, 1],
  Red, Arrowheads[0.02], Arrow[Tube[{{0, 0, 1.5}, {0, 0, 2}}, 0.04]],
  Blue, Arrowheads[0.01], 
  Arrow[Tube[{{0.3, 0, -1.2}, {0.8, 0, -1.7}}, 0.003]],
  Blue, Arrowheads[0.01], 
  Arrow[Tube[{{-0.3, 0, -1.2}, {-0.8, 0, -1.7}}, 0.003]],
  Blue, Arrowheads[0.01], 
  Arrow[Tube[{{0, 0.3, -1.2}, {0, 0.8, -1.7}}, 0.003]],
  Blue, Arrowheads[0.01], 
  Arrow[Tube[{{0, -0.3, -1.2}, {0, -0.8, -1.7}}, 0.003]],
  Blue, Arrowheads[0.01],

  Blue, Arrowheads[0.01], 
  Arrow[Tube[{{-0.3 Sqrt[2]/2, 0.3 Sqrt[2]/2, -1.2}, {-0.8 Sqrt[2]/2, 
      0.8 Sqrt[2]/2, -1.7}}, 0.003]],

  Dynamic[RotationTransform[Clock[{2 \[Pi], 0}, 5], {0, 0, 1}][{1, 0, 
     0}]], PlotRange -> 5, SphericalRegion -> True]

ParametricPlot3D[{x = 1.5 Cos[10 t], y = 1.5 Sin[10 t], 
  z = t}, {t, -1.2, 1.2}]

Following is the one that I don't want. I don't want the spiral curve to move anyway.

Show[Graphics3D[{Sphere[{0, 0, 0}, 1],
   Red, Arrowheads[0.02], Arrow[Tube[{{0, 0, 1.5}, {0, 0, 2}}, 0.04]],

   Arrow[Tube[{{0.3, 0, -1.2}, {0.8, 0, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{-0.3, 0, -1.2}, {-0.8, 0, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{0, 0.3, -1.2}, {0, 0.8, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{0, -0.3, -1.2}, {0, -0.8, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01],

       0.8 Sqrt[2]/2, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{-0.3 Sqrt[2]/2, 0.3 Sqrt[2]/2, -1.2}, {-0.8 Sqrt[2]/2,
        0.8 Sqrt[2]/2, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{0.3 Sqrt[2]/2, -0.3 Sqrt[2]/2, -1.2}, {0.8 Sqrt[2]/
        2, -0.8 Sqrt[2]/2, -1.7}}, 0.003]],
   Blue, Arrowheads[0.01], 
   Arrow[Tube[{{-0.3 Sqrt[2]/2, -0.3 Sqrt[2]/2, -1.2}, {-0.8 Sqrt[2]/
        2, -0.8 Sqrt[2]/2, -1.7}}, 0.003]]}, 
  Lighting -> {{"Directional", 
     RGBColor[0., 0.1, 0.01], {1, 0, 0}}, {"Directional", 
     RGBColor[0.605, 0.2, 0.1], {0.5, 0.5, 0}}, {"Directional",

     RGBColor[0.62, 0.215, 0.1], {0, -1, 0}}, {"Directional", 
     RGBColor[0.625, 0.22, 0.1], {-0.5, -0.5, 0}}, {"Directional", 
     RGBColor[0.63, 0.225, 0.1], {0, -1, 0}}, {"Directional", 
     RGBColor[0.635, 0.23, 0.1], {0.5, -0.5, 0}}}, Boxed -> False, 
  ViewPoint -> 
   Dynamic[RotationTransform[Clock[{2 \[Pi], 0}, 5], {0, 0, 1}][{1, 0,
       0}]], PlotRange -> 5, SphericalRegion -> True], 
 ParametricPlot3D[{x = 1.5 Cos[10 t], y = 1.5 Sin[10 t], 
   z = t}, {t, -1.2, 1.2}]]

enter image description here I want a static spiral curve and a rotating ball on the left with static arrows and an oppositely rotating ball on the right.
