The invention relates to the technical field of detection devices, in particular to an electronic expansion valve seat inner leakage detection device which comprises a box body and is characterized in that an electrical control cabinet is installed in the box body, a switch is installed on the electrical control cabinet, a collecting assembly is installed on the top of the electrical control cabinet, and a workbench is installed on the top of the box body. The device is simple in structure and high in practicability, the four functions of detection, fixing, recording and classification are arranged on one detection device, the working procedures are clear, compared with a traditional mechanical manual clamping fixture, pneumatic clamping is formed by providing an air source through an air pump, the clamping efficiency is greatly improved, and the working efficiency is improved. And the tensioning shell is fixed on the detection seat through the positioning pin, so that the position is more accurate, the measu
