[0039] The working principle of the above embodiment is:

[0040] (1) When the staff uses the drop hammer deflectometer body 4 to detect the ground, it is necessary to keep the bottom plate 1 stable and rotate the handle 203, thereby driving the bidirectional threaded rod 202 to rotate. The rotation of the bidirectional threaded rod 202 drives the two movable plates 204 to move relative to each other. At this time, the upper movable plate 204 drives the support seat 205 to move downward, and the lower movable plate 204 drives the universal wheel 206 to move upward. When the upper movable plate 204 moves, the sliding rod fixed on its left side moves in the inner cavity of the sliding groove, thereby improving the stability of the movement of the upper movable plate 204. When the lower movable plate 204 moves upward, the telescopic rod will be shortened, which can limit the movement of the lower movable plate 204 until the support seat 205 contacts the ground and the turning handle 203 can be stopped.

[0041] (2) After using the portable PEWD and testing the load plate, it needs to be stored. First, press the pressure plate 306 upward to shorten the compression rod 304 and compress the spring 305. At this time, the tester can be placed in the inner cavity of the installation slot 303, and then release the pressure plate 306. The spring 305 rebounds and drives the compression rod 304 to extend, so that the pressure plate 306 moves downward and the tester can be stored. Then place the end of the portable PEWD with the display screen on the upper surface of the support plate 308, and make the other end fit between the limit blocks 307 at the upper and lower ends. The portable PEWD can be stored, and then close the box door and fasten the chain buckle.
