[0002] The lubricating oil nozzle, also known as the injector, is a component in the lubricating oil system of an aircraft engine. The injector is a device that sprays oil into the engine. The lubricating oil is sprayed onto the lubricated parts through the nozzle to lubricate the parts, thereby reducing friction and wear on the mating surfaces and taking away the heat generated by friction. However, the flow rate value of the injector directly reflects the performance of the engine. When testing the flow rate of the injector, it is necessary to use testing equipment to test the injector to ensure its qualification.

[0003] At present, when using the detection equipment to detect the fuel injectors, the staff usually needs to remove the oil separator on the detection equipment, and then the staff needs to connect the fuel injectors to be detected to the various output ports of the oil separator in turn, and then install the oil separator with the fuel injectors on the equipment and fix it with threaded columns. After the installation is completed, the equipment is started to detect the flow rate. However, the current detection equipment is cumbersome to install and operate, and it is not convenient to install quickly, which makes it impossible for the staff to quickly detect the fuel injectors, thereby reducing the detection efficiency of the fuel injectors.
