For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0031] At present, the influence of the road subsidence on the safety of the vehicles running at high speed has gradually been paid attention to. In the industry, the road subsidence is usually measured by professional surveyors operating the theodolite, level and other civil engineering surveying instruments in a manual operation mode to know and monitor the subsidence and the subsidence value of each road section.

[0032] In the related art, the convex block on one side of the clamping plate is inserted into the insertion hole on the range finder to complete the installation by rotating the threaded rod, screwing the threaded rod with the clamping plate, and driving the two threaded rods to approach each other. However, the existing device drives the convex block to be inserted into the hole in the form of adjusting the rotating bolt during use, which is inefficient and slow in driving speed. Therefore, the installation and disassembly of the range finder cannot be quickly realized in actual use.

[0033] To solve the problems in the related art to some extent, the embodiment of the present application provides a road subsidence measuring tool. When the measuring rod 13 needs to be installed, the pressing ring 25 at the top of the measuring rod 13 is directly inserted into the inside of the pipe body 21. During the insertion process, the top of the pressing ring 25 will contact the clamping block 24 and retract the clamping block 24 into the groove 22 while moving upward, and at the same time, the clamping block 24 will press the spring one 23 to compress. After the clamping block 24 is disengaged from the pressing ring 25, the spring one 23 will rebound to push the clamping block 24 out of the inside of the groove 22, so that the pressing ring 25 cannot be pulled out of the inside of the pipe body 21, thereby completing the installation of the measuring rod 13. Then, the support 11 is placed on both sides of the road, the threaded rods on both sides of the support 11 are used to adjust the level, the level on the support 11 is observed, after the level is adjusted, the driving mechanism 12 is used to drive the pipe body 21 to move to the appropriate position, the pipe body 21 drives the measuring rod 13 to move to the appropriate position to observe the data on the measuring rod 13 and record it. Finally, the measuring rod 13 needs to be disassembled. Only the top of the measuring rod 13 needs to be inserted into the inside of the pipe body 21, at which time the movable ring 26 will also contact the clamping block 24. After the movable ring 26 moves above the clamping block 24 and is disengaged from the clamping block 24, the measuring rod 13 can be pulled downward. At this time, the clamping block 24 will push the movable ring 26 to move upward until the top of the movable ring 26 closes with the bottom of the pressing ring 25. Because the outer side of the movable ring 26 is designed as a slope, the clamping block 24 can be retracted until the clamping block 24 is disengaged from the movable ring 26 and the top of the movable ring 26 contacts the slope of the pressing ring 25, so that the pressing ring 25 is not limited and can be pulled out of the inside of the pipe body 21 to complete the disassembly.
