In this embodiment, a damper 404 is provided in the housing 401, and the lower end of the damper 404 is connected to the inertial member 402. The damper 404 has a certain stroke, the damper 404 can buffer the impact of the inertia element 402 when the road surface is a large hollow road surface, the damper 404 does not generate damping when the road surface is a general hollow road surface, so that the accuracy of the measurement result is ensured, and in the actual measurement process, the unevenness of the road is very small, the road surface is almost difficult to observe by naked eyes, the measurement of the large hollow road surface cannot occur, and therefore the design meets the actual requirement.
