An airtightness testing pressure head 5 is fixedly installed at the bottom of the cylinder 4. The base body 1 is composed of a rotating support assembly 6, a rotating support platform 7, several limiting support sleeves 1 8, and several limiting support sleeves 2 9. The rotating support platform 7 is fixedly connected to the top of the rotating support assembly 6, and the limiting support sleeves 1 8 and 2 limiting support sleeves 9 are symmetrically connected. The rotating support assembly 6, which is attached to both sides of the top of the rotating support platform 7, consists of a housing 10, a servo motor 11, a drive gear 12, a rotating shaft 13, an external gear ring 14, and a rotating disk 15. The servo motor 11 is fixedly connected to one side inside the housing 10, the drive gear 12 is fixedly connected to the output shaft of the servo motor 11, the rotating shaft 13 is rotatably connected to the inside of the housing 10, the external gear ring 14 is fixedly connected to the bottom end of the outer surface of the rotating shaft 13 and meshes with the drive gear 12, the rotating disk 15 is fixedly connected to the top of the rotating shaft 13, and the rotating support platform 7 is connected to the top of the rotating disk 15. In use, a set of items to be tested is placed inside the limiting support sleeve 8. The cylinder 4 drives the air tightness detection head 5 to move down and fit against the items to be tested, thus achieving air tightness detection. During this period, another set of items to be tested is placed inside the limiting support sleeve 9. After the first set of tests is completed, the rotating support assembly 6 drives the rotating support table 7, the limiting support sleeve 8, and the limiting support sleeve 9 to rotate 180 degrees, so that the second set of items enters the testing position. At this time, the staff can remove the first set of items and place the next set of items to be tested. The above steps are repeated to achieve continuous testing, improve testing efficiency, and reduce waiting time. When the rotating support assembly 6 is working, the servo motor 11 drives the drive gear 12 to rotate, the drive gear 12 drives the outer gear ring 14 to rotate, the outer gear ring 14 drives the rotating shaft 13 to rotate, the rotating shaft 13 drives the rotating disk 15 to rotate, and the rotating disk 15 drives the rotating support table 7 to rotate.
