[0002] Currently, most of the integrated systems inside the aircraft are embeddedly assembled after the structure is assembled into a barrel. With the continuous improvement of aircraft assembly efficiency, in order to meet the installation quality of the aircraft, for the installation of the aircraft integrated system, the traditional method simply relies on manual handling, pushing and pulling for installation, which not only takes time and effort and affects the product production progress, but also easily causes damage to the integrated system and the surrounding structure during the handling and installation process. Therefore, it is necessary to design a device with hoisting and squeezing clamping functions to ensure the installation quality of the integrated system. Summary of the Invention
