The stress sensor 5 is installed on the inner side of the rotating plate 7. The rotating plate 7 structure allows the sensor to be adjusted along with the mounting surface, thereby improving the fit between the sensor and the surface of the steel structure, thereby enhancing the accuracy of stress conduction; rotating shafts are installed at the central positions of the upper and lower ends of the rotating plate 7, and the rotating plate 7 rotates with the left unit fixed plate structure 1 through the rotating shaft, and the upper and lower sides of the left unit fixed plate structure 1 are equipped with center-aligned The fixing bolt 8 is provided, and one end of the fixing bolt 8 is spirally connected to the rotating plate 7. This arrangement can better fix the rotating plate 7, thereby facilitating subsequent stable measurement and use; the fixing device 6 includes a symmetrically arranged fixing block 61, one side of the fixing block 61 is arranged in an arc shape, and a slider is installed on the other side of the fixing block 61.

[0026] Working process: When the device is actually used, first rotate the rotating plate 7 and select the front and back of the right unit fixing plate structure 2 according to the shape of the object to be tested. When the object to be tested is a tubular object, the fixing device 6 can be faced inward, and the stress sensor 5 can be rotated to the inside. Then, the left unit fixing plate structure 1 and the right unit fixing plate structure 2 are fixed to the outside of the object to be tested by the threaded rod 3 and the nut 4; then, by rotating the rotary valve 626 of the positioning structure 62, the screw 622 is driven to rotate through the transmission chain 625 and the transmission wheel 623, and then the fixing block 61 is driven to move through the fixing cylinder 621, thereby ensuring a stable fixing effect. Finally, the stress data can be detected by the stress sensor 5; when the object to be tested is a planar structure, the rotating plate 7 is reversed, and the side of the right unit fixing plate structure 2 with the support block 9 is turned inward. Finally, the position of the stress sensor 5 is adjusted by rotation, and the device can be installed by the threaded rod 3 and the nut 4.
