[0063] After the inspection of the liquefied gas cylinder body 3 is completed, the staff places the inspected liquefied gas cylinder body 3 on the right support mechanism 2, and then starts the servo motor B603. When the servo motor B603 works, the circular driving rod B602 drives a row of rubber driving wheels B604 to rotate, thereby realizing the automatic rotation of the inspected liquefied gas cylinder body 3, which is convenient for drying different positions of the inspected liquefied gas cylinder body 3; when the two linkage cams 605 rotate, the active booster plate 607 moves between the two linkage cams 605 and the two complex cams 605. It reciprocates up and down under the action of the positioning spring 610; when the movable booster plate 607 moves downward, the gas in the rectangular hollow cover 606 is discharged through two rows of drying elbows 608, which increases the air flow rate outside the liquefied gas cylinder body 3, which is beneficial to the drying of the liquefied gas cylinder body 3 after detection; when the movable booster plate 607 moves upward, the external gas enters the rectangular hollow cover 606 through two rows of drying elbows 608, which can also increase the air flow rate outside the liquefied gas cylinder body 3, which is beneficial to the drying of the liquefied gas cylinder body 3 after detection.
