[0029] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, a moving seat 2 is provided on the top surface of the workbench 1. A rotating assembly is provided inside the moving seat 2. A rotating ring 13 is provided on one side of the moving seat 2, and the rotating ring 13 is connected to the rotating assembly. The rotating assembly is composed of a worm gear 21, a worm 22 and a rotating rod 20. One end of the rotating rod 20 is fixedly connected to the rotating ring 13, and the other end of the rotating rod 20 is fixedly connected to the worm gear 21. A worm 22 is meshed and connected to one side of the worm gear 21. A rotating motor 16 is provided on the top surface of the moving seat 2, and the output end of the rotating motor 16 is connected to the worm 22. Thus, the worm 22 can be driven to rotate by the rotating motor 16. An adjusting assembly is provided on the top surface of the moving seat 2, and the adjusting assembly is composed of a screw rod 23, a moving block 24, a guide rod 25 and a guide block 26. The guide block 26 and the moving block 24 are fixedly connected to the top surface of the moving seat 2. The screw rod 23 passes through the inside of the moving block 24, and the screw rod 23 is threadedly connected to the moving block 24. The guide rod 25 passes through the inside of the guide block 26, and the guide rod 25 is slidably connected to the guide block 26. Thus, when the screw rod 23 rotates, the moving block 24 can be driven to move on the screw rod 23. When the moving block 24 moves, the guide block 26 can be driven to move on the guide rod 25 by the moving seat 2. Thus, the directivity and stability of the moving seat 2 during movement can be ensured. Two adjusting grooves 9 are opened on the top surface of the workbench 1, and the screw rod 23 and the guide rod 25 are respectively placed inside the two adjusting grooves 9. Thus, when the moving seat 2 moves, it can move along the opening direction of the adjusting groove 9. An adjusting motor 17 is fixedly installed on one side of the workbench 1 through a fixing frame, and the output end of the adjusting motor 17 is connected to the screw rod 23. Thus, the screw rod 23 can be driven to rotate by the adjusting motor 17. A second bolt 18 passes through the surface of the rotating ring 13, and the connection between the second bolt 18 and the rotating ring 13 is threadedly connected. Therefore, by rotating the second bolt 18, the length extending into the inner side of the rotating ring 13 can be adjusted by the second bolt 18. The bottom end of the second bolt 18 is movably connected to an arc-shaped plate 19, and the arc-shaped plate 19 is placed inside the rotating ring 13. A bearing 11 is fixedly installed on one side of the workbench 1. A positioning ring 12 is installed at the rotating end of the bearing 11. A first bolt 14 passes through the surface of the positioning ring 12, and the connection between the first bolt 14 and the positioning ring 12 is threadedly connected. Therefore, by rotating the first bolt 14, the length extending into the inner side of the positioning ring 12 can be adjusted by the first bolt 14. The bottom end of the first bolt 14 is movably connected to a lower pressing plate 15, and the lower pressing plate 15 is placed inside the positioning ring 12, and the bottom surface of the lower pressing plate 15 is arc-shaped. During use, the two ends of the steel pipe can be respectively placed inside the positioning ring 12 and the rotating ring 13, and then the first bolt 14 and the second bolt 18 are rotated to drive the lower pressing plate 15 and the arc-shaped plate 19 to be in full contact with the two ends of the steel pipe respectively. Thus, the two ends of the steel pipe can be fixed inside the positioning ring 12 and the rotating ring 13. When the rotating assembly drives the rotating ring 13 to rotate, the rotating ring 13 can drive the positioning ring 12 to rotate at the rotating end of the bearing 11 through the clamped and fixed steel pipe. When the positioning ring 12 and the rotating ring 13 rotate,It can drive the clamped and fixed steel pipe to rotate smoothly. The rotatable steel pipe is convenient for detecting the pressure resistance performance at different positions, and the steel pipe does not need to be detached from the fixed state during the detection process, increasing the convenience of detection;

[0030] It should be noted that the positions of the positioning ring 12 and the rotating ring 13 of this device are on the same horizontal line as the positions of the two arc grooves 4. And because their surfaces are both arc-shaped, when the two ends of the steel pipe are placed inside the positioning ring 12 and the rotating ring 13, the middle part can also be vertically placed flat inside the arc groove 4. The total length of the first bolt 14 and the second bolt 18 of this device is less than the distance from the bottom surfaces of the positioning ring 12 and the rotating ring 13 to the top surface of the workbench 1. Therefore, when the rotating ring 13 and the positioning ring 12 rotate, the first bolt 14 and the second bolt 18 will not contact the top surface of the workbench 1;

[0031] When further using this device, place the two ends of the steel pipe inside the positioning ring 12 and the rotating ring 13 respectively. Since the positions of the positioning ring 12 and the rotating ring 13 are on the same horizontal line as the positions of the two arc grooves 4, the steel pipe can be vertically placed inside the arc groove 4. By rotating the first bolt 14 and the second bolt 18, the lower pressing plate 15 and the arc-shaped plate 19 are respectively driven to move downward, making the lower pressing plate 15 and the arc-shaped plate 19 fully contact the surface of the steel pipe, so as to fix the steel pipe, and then it is convenient to detect its pressure resistance performance. When detecting different positions of the steel pipe, start the rotating motor 16. The rotating motor 16 drives the worm 22 to rotate, the worm 22 drives the worm wheel 21 to rotate, the worm wheel 21 drives the rotating rod 20 to rotate, the rotating rod 20 drives the rotating ring 13 to rotate, and the rotating ring 13 drives the positioning ring 12 to rotate inside the bearing 11 through the clamped and fixed steel pipe. When the rotating ring 13 and the positioning ring 12 rotate synchronously, the steel pipe can be driven to rotate smoothly. Therefore, different positions of the steel pipe can be detected, and it is no longer necessary to frequently release the fixed state of the steel pipe during this process, improving the detection efficiency. By starting the adjusting motor 17, the adjusting motor 17 drives the screw rod 23 to rotate, the screw rod 23 drives the moving block 24 to move along the adjusting groove 9, the moving block 24 drives the moving seat 2 to move. When the moving seat 2 moves, the distance between the positioning ring 12 and the rotating ring 13 can be adjusted, so as to fix and detect steel pipes of different lengths;

[0032] Specific working principle: Place this device at the designated position, and place the two ends of the stainless steel steel pipe inside the positioning ring 12 and the rotating ring 13 respectively. At this time, a part of the middle end of the steel pipe is placed vertically and flat inside the arc groove 4. By rotating the first bolt 14 and the second bolt 18, the first bolt 14 and the second bolt 18 drive the lower pressing plate 15 and the arc-shaped plate 19 to move downward respectively, so that the lower pressing plate 15 and the arc-shaped plate 19 are in full contact with the two ends of the steel pipe, and thus the steel pipe can be fixed. By starting the hydraulic rod 5, the hydraulic rod 5 drives the pressure plate 6 to move downward, and controlling the downward pressure of the hydraulic rod 5, the pressure plate 6 can detect the pressure resistance performance of the steel pipe. By retracting the hydraulic rod 5, the steel pipe is disengaged from the detection state. By pulling the sliding seat 3 along the sliding groove 8 with the handle 7, the position of the detection component can be changed, and thus different positions of the steel pipe can be detected. When further detecting different positions of the steel pipe, start the rotating motor 16, the rotating motor 16 drives the worm 22 to rotate, the worm 22 drives the worm wheel 21 to rotate, the worm wheel 21 drives the rotating rod 20 to rotate, the rotating rod 20 drives the non-rotating ring 13 to rotate, and the rotating ring 13 drives the positioning ring 12 to rotate inside the bearing 11 through the clamped and fixed steel pipe. When the positioning ring 12 and the rotating ring 13 rotate synchronously, the clamped and fixed steel pipe can be driven to rotate stably, and thus different surfaces of the steel pipe can be opposite to the lower pressing plate 15, and further different positions of the steel pipe can be detected. Moreover, this process can be realized without frequently releasing the fixed state of the steel pipe, which greatly improves the detection efficiency. By starting the adjusting motor 17, the adjusting motor 17 drives the screw rod 23 to rotate, the screw rod 23 drives the moving block 24 to move, and the moving block 24 drives the moving seat 2 to move. When the moving seat 2 moves, the distance between the seat positioning ring 12 and the rotating ring 13 can be adjusted, so as to facilitate the positioning and detection of steel pipes of different lengths.
