The moving block 5010 drives the corresponding plug 5011 to plug both ends of the elbow, sealing and fixing the elbow. No manual operation is required, which saves time and improves testing efficiency. After fixing is completed... Air is pumped into the air pipe 5012 via an external air pump. The air pipe 5012 pressurizes the elbow through one of the plugs 5011. Then, the third servo motor 601 drives the sliding block 603 to move via the bidirectional threaded rod 602. The sliding block 603 drives the corresponding push rod 605 to move via the first moving frame 604. The push rod 605 drives the moving plate 2 to move downward via the second moving frame 606, so that the water in the reservoir submerges the elbow, making it easier for staff to observe whether there are air bubbles. Pulling the sliding rod 702 causes the locking post 703 to move, so that the locking post 703 disengages from the locking hole. Then the locking block is removed, making it easier for staff to replace the severely worn rubber gasket.
