The electric push rod 10 is started, which drives the push plate 11 to move. The push plate 11 moves the mounting plate 13 and moves the positioning component 17. The fabric fixed on the positioning component 17 is in contact with the air permeability testing device body 7. The air permeability testing device body 7 performs air permeability testing on the fabric. While testing, the other tested fabrics can be removed and replaced with the fabric to be tested. Multiple sets of fabrics can be tested continuously without the need for frequent manual replacement of fabric positions, which greatly improves the testing efficiency.

[0035] Place the fabric above the connecting plate 171, press the control button 172 to start the second motor 1711.
