[0009] The method further comprises: one end of the first passage is fixedly connected to the first air inlet connector, and the other end of the first passage is fixedly connected to the first air return connector;

[0010] One end of the second passage is fixedly connected to the second air inlet connector, and the other end of the second passage is fixedly connected to the second air return connector.

[0011] The plug connection holes on the front side of the first base block are arranged in a row, and a front positioning hole is respectively provided at both ends of the row of plug connection holes;

[0012] The socket holes on the rear side surface of the second base block are arranged in a row, and a rear positioning hole is respectively provided at both ends of a row of socket holes.

[0013] The upper and lower side surfaces of the first base block and the second base block are both provided with connection holes for connecting to a workbench.

[0014] Both ends of the first passage and the second passage are respectively provided with flange holes for connecting corresponding joints.

[0015] One end of the positioning piece is fixedly connected to the front positioning hole, and the other end of the positioning piece is plug-fittingly connected to the rear positioning hole.

[0016] The positioning member includes a positioning pin, one end of which is provided with an external thread; the front positioning hole is a threaded hole, the end of the positioning pin with the external thread is fixed in the front positioning hole, and the other end of the positioning pin is inserted into the rear positioning hole in a clearance fit manner.

[0017] A limiting nut is installed on the threaded section of the positioning pin.

[0018] The beneficial effects of the present invention are:

[0019] The two separate first and second base blocks enable simultaneous bidirectional testing of the fluid connector plug and socket, significantly improving the comprehensiveness and efficiency of testing. This allows a single test to cover more test scenarios, reducing the number of tests and test time, and optimizing the test process.

[0020] The tooling can test multiple plugs and sockets simultaneously, thus significantly saving time during large-scale testing. By controlling the various air inlet and return air connectors, testing can be performed flexibly, further improving test efficiency. The plug and socket connectors on the tooling facilitate the connection of the test pieces. Additional positioning parts ensure that the plugs and sockets correspond one-to-one when the first and second base blocks are docked, thereby simplifying the test operation process.
