The invention provides a self-locking structure. The self-locking structure comprises a slide block, a limiting block, guide parts, a rotary part, a blocking part and a blocking strip, wherein the limiting block is arranged at one side of the slide block, can pass through the guide parts to slide relative to the slide block, and can block the rotary part while being closet to the slide block; the rotary part is in rotary connection to the slide block; the blocking part is also in rotary connection to the rotary part, but is not connected to the slide block; two rotary centers are not coaxial, so that the rotary part can drive the blocking part to rotate around the rotary center of the rotary part relative to the slide block; a first limiting part is arranged on the slide block; a second limiting part is arranged on the rotary part; the blocking strip is distributed at one side of the slide block, is parallel to the guide parts, and adopts an oblique-tooth structure for blocking the blocking part which is in c
