The invention belongs to the technical field of single-nail double-shear test of aircraft composite laminates, and particularly relates to a single-nail double-shear test structure of an aircraft composite laminate, which is characterized in that two bushings are designed to transfer load between a pull plate and the composite laminate, and when the bushings are deformed or the aperture of a loading hole is changed, the pull plate and the composite laminate are connected with each other; in addition, the jackscrews are arranged on the two pulling plates to be matched with the base plate, the distance between the ends, connected with the chuck of the testing machine, of the two pulling plates can be easily adjusted by screwing the jackscrews to be consistent with the thickness of the composite laminated plate, and therefore the loading effect of the composite laminated plate can be guaranteed. Therefore, the dispersity of a test result is reduced. 本申请属于飞机复合材料层合板单钉双剪试验技术领域，具体涉及一种飞机复合材料层合板单钉双剪试验结构，设计利用两个衬套在拉板、复合
