[0002] In recent years, with the development of science and technology at home and abroad, unmanned aerial vehicles (UAVs) have been widely used in various industries, gradually penetrating into the applications of various industries, and the market scale has also been expanding year by year. The wet multi-disc torque limiter of UAVs is a core component participating in transmission, which can play a good overload protection function for the UAV transmission system, prevent the power system of the transmission part from being damaged due to torque overload, and effectively avoid the occurrence of faults in the transmission system during the flight operation of the UAV.

[0003] In order to avoid faults in the torque limiter during operation, generally, a torque limiter bench test is first carried out on the torque limiter to ensure that the performance of the torque limiter can meet the usage standards of UAVs. Most of the existing torque limiter bench test devices need to be assisted by other tools for positioning during the installation and disassembly of the torque limiter, and cannot use an oil pump to achieve circulating cooling. During the test process, a large amount of oil fluid is required to complete the test operation;

[0004] Therefore, most of the existing torque limiter bench test devices need to be fixed with more tools and components to complete the fixation of the torque limiter, which is not convenient for alignment, disassembly and assembly. Moreover, if the installation is not in place, the test results of the torque limiter will also be affected. Content of the Utility Model
