Endoscope capsule controller and reducer bending-resisting device thereof

The invention discloses a reducer bending-resisting device, which comprises hollow rotating shafts which sleeve peripheral parts of reducer transmission shafts and are fixedly connected to reducer fixed ends, bearing bases which sleeve the peripheral parts of the hollow rotating shafts, and bearings which are arranged between the hollow rotating shafts and the bearing bases, wherein by virtue of the bearings, the bearing bases can rotate along the hollow rotating shaft. According to the reducer bending-resisting device provided by the invention, by virtue of anti-bending-moment structures composed of the bearings, the bearing bases and the hollow rotating shafts, a reducer, instead of bearing a high bending moment, is mainly in charge of transmitting a torque moment, so that the reducer just needs to select a proper model in accordance with the torque moment; therefore, the size of the reducer is effectively diminished, a space is saved and cost is reduced. The invention also discloses an endoscope capsule co
