In a very long year of life, people conquer nature and have a desire to soar the sky and roam the universe. In an era with low productivity and low level of science and technology, this desire can only be held at the fantasy stage. Although the search and attempt of flying have been made for a long time, the desire to achieve this has started with the 18 th century of hot air balloon ascent. The ancient dream of humans flying in the atmosphere was really realized since the first powered, steerable aircraft completed a brief flight in the beginning of the 20 th century. Through the hard efforts of many outstanding figures, the aeronautical science and technology is rapidly developed, and the performance of airplanes is continuously improved. Human beings gradually gain freedom of movement in the atmosphere and also enhance the confidence of flying out of the atmosphere. By the middle of the 50 s, the first artificial earth satellite was successfully launched on the basis of the remarkable progress of scientific technologies such as rockets, electronics, automatic control and the like, and the new territory that human spaceflight begins to become human activities was created. The development of aerospace industry is the result of the leap progress of scientific technology in the 20 th century and the leap forward of social production. Aerospace efforts have focused on numerous new achievements in science and technology. Although the former few steps of the cradle are leaving the earth, the aerospace activity has been far beyond the scientific and technical field, and has a wide and profound impact on political, economic, military and even human social life. A large number of nuts are needed to be used for connecting and fastening equipment parts in the assembling process of the aerospace equipment, and due to the particularity of the aerospace equipment, the nuts used by the aerospace equipment need to be strictly detected to prevent accidents. In the nut monitoring process, the nut needs to be fixed by using a clamp, so that the nut is convenient to detect.
