In addition, the airtight testing device also includes an elastic component 400, and the airtight joint 300 is elastically connected to the movable end through the elastic component 400, so that the airtight joint 300 can float relative to the movable end. In the present solution, the position of the airtight joint 300 in the X, Y and Z directions is adjusted by the position adjustment mechanism 200, so that the airtight joint 300 can be accurately docked with the product to be tested, thereby improving the accuracy of the airtight test. In addition, the setting of the elastic component 400 allows the airtight joint 300 to float.
