[0002] In order to ensure the safe use of seamless gas cylinders, in accordance with national requirements, seamless gas cylinders must be strictly inspected before use. The existing technology generally uses an external measurement method water pressure test device to detect the elastic deformation and plastic deformation of the bottle body. The external measurement method water pressure test device requires a larger open space to place the seamless gas cylinder. The seamless gas cylinder is manually moved and connected to the rotary tightening device. The rotary tightening device and the seamless gas cylinder are then lifted by a lifting equipment and transferred together to the water jacket. The seamless gas cylinder is then manually sealed in the water jacket for testing. The above-mentioned single-bottle inspection work requires multiple operators to complete, resulting in the existing water pressure test device not only occupying a large space, but also being prone to shaking during the transfer of seamless gas cylinders. Not only does it pose a safety hazard to the operator, but it also has the defect of low production efficiency.

[0023] like Figure 1 , Figure 4 As shown, the clamping limit mechanism includes an upper clamping limit cylinder 11a and a lower clamping limit cylinder 11b located on one side of the seamless gas cylinder 4; the clamping mechanism is an upper clamping limit cylinder 13a and a lower clamping limit cylinder 13b located on the other side of the seamless gas cylinder 4; the upper clamping limit cylinder 11a and the upper clamping limit cylinder 13a are symmetrically arranged on the frame 1 on both sides of the upper part of the seamless gas cylinder 4 (the upper two sides refer to the two sides of the cylindrical surface close to the lower part of the top arc surface of the seamless gas cylinder 4); the lower clamping limit cylinder 11b and the lower clamping limit cylinder 13b are symmetrically arranged on the frame 1 on both sides of the lower part of the seamless gas cylinder 4 (the lower two sides refer to the two sides of the cylindrical surface close to the bottom of the seamless gas cylinder 4).
