The inner side of the limiting block 742 is fixedly connected to the first spring 743. Through the above arrangement, the inclination angle of the anti-reverse pad 71 can be understood through the indicating needle 744. As a further technical solution of this solution, the indicator needle 744 is arranged on one side of the scale groove 64, the top of the indicator needle 744 is sharp, and the angle between the indicator needle 744 and the rotating shaft 741 is 90°.

During the connection process, the locking bolt 5 is connected to the expansion bolt 4 to achieve the positioning of the connecting frame 3. During the installation of the locking bolt 5, the anti-reverse pad 71 is squeezed.

After the inclination sensor 1 is fixed, the inclination is kept the same as that of the building wall, thereby ensuring the accuracy of the detection data; Later in the detection process, construction activities such as piling, tamping, blasting and vibration rolling at the construction site will generate strong vibrations. These vibrations will be transmitted through the soil and building structures, causing vibrations in the building walls. In addition, the operation of heavy machinery and equipment used in the construction process will also cause vibrations, which will cause the connecting frame 3 to loosen. At this time, tighten the control bolt 76. During the movement of the control bolt 76, the movement of the ring plate 753 is controlled by the inclined block 751, so that the adsorption hole 73 adsorbs the locking nut 5, which can effectively prevent the locking nut 5 from loosening due to vibration during use, thereby effectively improving the accuracy of the detection data of the inclination sensor 1.
