Zusammenfassung:	The combined type non-loosening nut can effectively prevent mechanical parts from loosening when the mechanical parts are vibrated due to high-strength stress. A gap exists between the nut and the screw, and the gap can be increased along with the increase of stress, which is the main reason of nut loosening and wire drawing. The nut is characterized by comprising an inner nut and an outer nut, a power arm of the outer nut is larger than that of the inner nut, only a screw rotates when stressed, and the outer nut can reduce a gap between the nut and a screw rod to the minimum under the stressed condition by utilizing the counter-acting force of a connected object and the characteristics of a cone, so that the friction force between the nuts is increased, and the service life of the nut is prolonged. And nut loosening and wire drawing are effectively prevented. The locknut is characterized by being a substantial progress of all locknuts. The combined type non-loosening nut is widely applied to high-speed rails
