[0036] Turn the adjusting bolt 10 to move it outward until it disengages from the threaded hole 8, then pull the adjusting column 9 to lift it. The adjusting column 9 drives the mounting plate 11 to lift, and the mounting plate 11 drives the sensing column 12 to lift until the sensing column 12 contacts the left top surface of the detection lever 13. Then drive the vehicle through the other side of the detection lever 13. The road surface will sink after the wheel rolls over it.
