[0034] Example 2:
[0035] Please see Figure 1-11 As shown, based on Embodiment 1, the present invention provides a technical solution: the position adjustment mechanism 2 7 includes a connecting frame 18 and an adjusting rod 20. The connecting frame 18 is fixed to the front end of the adjusting block 17, and the rear end of the adjusting rod 20 extends into the connecting frame 18. The upper and lower ends of the adjusting rod 20 are rotatably connected to the upper and lower inner walls of the connecting frame 18, respectively. A sliding frame 22 is slidably connected to the adjusting rod 20. A fixing bolt 23 is provided on the right side of the sliding frame 22. The left end of the fixing bolt 23 penetrates the right side wall of the sliding frame 22 and abuts against the right end of the adjusting rod 20. The left end of the sliding frame 22 is fixedly connected to the right end of the abutting screw 24.
[0036] Two position holes 21 are provided on the connecting frame 18, and a threaded connection groove 34 is provided on the adjusting rod 20.

The two position holes 21 enable the position adjustment mechanism 7 and the detection abutment mechanism 8 to be adjusted, thereby further improving the adaptability of the device.
[0037] In this embodiment, during use, the position of the sliding frame 22 in the front-to-back direction can be adjusted by loosening the fixing bolt 23. After adjusting to the appropriate position, the fixing bolt 23 can be tightened. When it is necessary to adjust the position of the position adjustment mechanism 7 and the detection abutment mechanism 8, the limiting bolt 19 is separated from the threaded connection groove 34, the adjusting rod 20 is rotated, and after the threaded connection groove 34 is adjusted to the position of the other position hole 21, the limiting bolt 19 is then passed through the other position hole 21 and engaged with the threaded connection groove 34.
[0038] Working principle: In use, pull out the clamping screw 5 and place the fixed frame 1 and lower clamping plate 4 on the outside of the steel structure. Then, pass the clamping screw 5 through the upper side wall of the fixed frame 1 and thread it into the lower clamping plate 4. By rotating the clamping screw 5, the steel structure is clamped by the cooperation of the lower clamping plate 4 and the fixed frame 1, thereby fixing the position of the device. The position of the detection abutment mechanism 8 is adjusted according to the position to be detected. During adjustment, rotating the adjusting plate 15 drives the adjusting screw 16 to rotate. The adjusting screw 16 cooperates with the adjusting block 17, thereby driving the detection abutment mechanism 8 and the position adjustment mechanism 2 7 to move in the vertical direction. Loosening the locking plate 12 allows the position adjustment mechanism 1 6 to rotate, thereby adjusting the position adjustment mechanism 1 6, the position adjustment mechanism 2 7, and the position adjustment mechanism 3 7. The position of the contact mechanism 8 is rotated to adjust the angle. After the position is adjusted, the locking plate 12 is tightened. Loosening the fixing bolt 23 adjusts the position of the sliding frame 22 in the front-back direction. After adjusting to the appropriate position, the fixing bolt 23 is tightened. The contact mechanism 8 is equipped with an internal threaded contact cylinder 25 and a contact screw 24 to adjust the position of the contact block 33. During testing, the internal threaded contact cylinder 25 is rotated to push the contact block 33 to the position to be tested. After the contact block 33 abuts against the position to be tested, the internal threaded contact cylinder 25 is rotated. When the position pointer 29 points to the zero mark of the testing scale 30, it can adapt to the stress changes of the steel structure in both left and right directions, thus completing the stress test.
