  4. 根据权利要求3所述搅拌机，其特征在于：输出轴支架(2)和内齿圈(4)内分别设有用于和行星齿轮组(3)啮合的内齿。
  5. 根据权利要求4所述搅拌机，其特征在于：输出轴支架(2)、内齿圈(4)的内齿分别呈圆周式设置。
  6. 根据权利要求3所述搅拌机，其特征在于：凹凸配合组件包括设置在内齿 圈(4)上的凸筋(4.2)或凹陷，以及设置在下盖(8)内的凸筋或凹陷(8.1)，凸筋(4.2)嵌入凹陷(8.1)内。
  7. 根据权利要求1所述搅拌机，其特征在于：箱体包括上盖(7)和下盖(8)，下盖(8)内设有用于形成凹凸配合组件的凸筋或凹陷(8.1)，下盖(8)和上盖(7)内还分别设有用于形成滑轮组件起伏的波浪槽。
  8. 根据权利要求1所述搅拌机，其特征在于：中心轮(5)内表面设有用于和输出轴(1)、输入轴(6)啮合的花键。
  9. 根据权利要求1所述搅拌机，其特征在于：输出轴(1)和中心轮(5)或行星齿轮组(3)之间用螺钉轴向固定；或者，输出轴(1)和中心轮(5)或行星齿轮组(3)以内外螺纹形式紧固。
