The left and right ends of the mounting shell 9 are fixedly connected with the spring, and the connecting rod 13 fixed at the upper end of the mounting shell 9 forms a rotating structure with the mounting frame 7. When using the detection device, first push the mounting frame 1 to the concrete road, then remove the limit bolt 4, and adjust the column 3 to expose the support tube 2 to a suitable height, then retighten the limit bolt 4 to make the impact plate 12 fit with the road surface.
