[0002] During the assembly stage of an aircraft, a large number of support plate nuts are often used. Since the support plate nuts are small and used frequently, it is inconvenient for an operator to pick them up. When adjusting the position of the support plate nuts and tightening the process screws, the adjustment process is time-consuming and labor-intensive. Using the support plate nuts in the usual way often has the following main problems:

[0003] (1) The support plate nuts are inconvenient to pick up, and each is picked up once for use. Frequent use is time-consuming and labor-intensive.

[0004] (2) The labor intensity of workers is high. When adjusting the position of the support plate nuts and tightening the process screws, the position needs to be carefully adjusted and fixed with other auxiliary tools to prevent the position of the support plate nuts from shifting when the process screws are tightened. This is relatively energy-consuming and lacks standardized and specialized tools.
