Simultaneously, a carbon fiber extension rod 6 is fixedly installed at the end of the adapter screw 5 away from the universal ball 4. The carbon fiber extension rod 6 has two sections, which increase the overall height of the device, making it easy to install and observe. Meanwhile, a level 11 is fixedly installed on the outside of the carbon fiber extension rod 6. When the carbon fiber extension rod 6 is fixedly connected to the adapter screw 5, the universal ball 4 and the universal joint gimbal 3 are rotated to adjust the angle of the carbon fiber extension rod 6. The level 11 determines whether the carbon fiber extension rod 6 is vertical. During the experiment, according to different loading stages, the level 11 and the barcode-labeled indium steel ruler 8 are used to detect the deflection of the tested component 2. The observation instrument 13 is used to observe and record the different stages, achieving improved detection accuracy and processing efficiency, eliminating the need for multiple dial gauges for testing.

[0042] Secondly, a knob 9 engages with the outer side of the mounting sleeve 7, and the knob 9 contacts the outer side of the barcode sticker steel ruler 8. When it is necessary to adjust the height of the barcode sticker steel ruler 8, the adjustment can be made by the sliding action between the mounting sleeve 7 and the barcode sticker steel ruler 8. At the same time, it is fixed by the engagement action between the knob 9 and the mounting sleeve 7, so as to facilitate the adjustment of the height of the top ball 10.

[0043] Finally, a groove 17 is provided inside the permanent magnet chuck switch magnet base 15, and a slider 18 is slidably connected inside the groove 17. A connecting block 19 is fixedly installed at the end of the slider 18 away from the groove 17, and an infrared rangefinder 20 is fixedly installed on the side of the connecting block 19 away from the slider 18. There are four infrared rangefinders 20, which are arranged at equal angles around the four directions of the permanent magnet chuck switch magnet base 15. When the device is installed, the distance between different devices can be detected by emitting lasers through the infrared rangefinders 20, so that the installation distance of the devices is equal, thereby maintaining the uniform installation of the devices and making the detected values ​​more accurate.
