[0003] For example, a device for detecting the sealing properties of seamless steel cylinders is recorded in the patent with patent announcement number CN215414236 U. The scheme recorded therein clamps and fixes the seamless steel cylinder after the clamping mechanism is started by a controller, and the controller controls the telescopic cylinder to start. After the telescopic cylinder drives the clamping mechanism to move downward a set distance, the clamping mechanism is located in the water in an open water tank, and the seamless steel cylinder is located in the water in the open water tank at the same time. The controller controls the telescopic cylinder to self-lock, and the seamless steel cylinder is left standing in the water for a set time to see if bubbles are generated. The seamless steel cylinder can be fully detected without omissions.

A bidirectional screw rod 606 is rotatably connected inside the support frame 604. The threads at both ends of the bidirectional screw rod 606 are both threadedly connected to the inside of the clamping block 605. An adjustment assembly for adjusting the movable column 602 is provided on one side of the U-shaped block 601. By rotating the bidirectional screw rod 606, it drives the two clamping blocks 605 to move closer to or away from each other in the support frame 604.
