Meanwhile, the structure is widely used in the brake, throttle and gear shifting of automobiles, motorcycles and ships. The aircraft engine control system transmission cable works around the aircraft engine in an extremely high temperature environment. When working, the transmission cable moves back and forth in the metal sheath, and a large amount of metal chips are generated by the friction between the two, which are accumulated at the bending deformation part. If not cleaned in time, the control rod may be stuck, which seriously endangers the flight safety. According to the aircraft operation procedures, the engine control system transmission cable must be cleaned and lubricated regularly.
