[0052] Working principle: Under the action of the wheels at the bottom of the outer frame 101, the device is pushed to the position of the road to be tested, and then the upper and lower driving modules 102 are opened to drive the punch 201 and the drill sleeve 202 to move downward, and then the punch 201 is opened to drive the drill sleeve 202 to sample the road surface. When the sampling is completed, the upper and lower driving modules 102 and the punch 201 are closed, and then the nut 306 is unscrewed, and the fixing screw 305 is taken out from the first through hole 303 and the second through hole 304, and then the receiving block 203 is removed from the slot 302, and then the drill sleeve 202 is removed, and then the screw rod 206 is taken out, and the rectangular rod 208 is held, and the screw rod 206 is rotated at the first threaded hole 204 and the second threaded hole 205. At this time, the screw rod 206 pushes the circular pad 207 to move downward, and then the sample is ejected from the drill sleeve 202;

[0053] This step allows the sample to be removed quickly and conveniently without damaging the components.
