[0031] Working principle:

[0032] When in use, the cover plate 12 in the protection component 2 is opened and placed horizontally. At this time, the bottom end of the fixed rod 19 in the stabilizing component 21 is placed between the fixed blocks 17. The rotating rod 18 is rotated to be inserted into the insertion hole 20 of the fixed rod 19, and the position of the cover plate 12 is fixed. Then the user can pull out the bottom rod 7 and the grading rod 5 in the detection component 1. The bottom rod 7 and the grading rod 5 that are not in contact with the handle 3 slide in the retraction cavity 6 and contact the protrusion 8. Since the outer diameters of the grading rod 5 and the bottom rod 7 are the same as the inner diameter of the retraction cavity 6, the protrusion 8 can greatly increase the grading capacity. The friction between the rod 5 and the bottom rod 7 and the inner wall of the retraction chamber 6 means that the user can fix the positions of the grading rod 5 and the bottom rod 7 at will when pulling, and when the groove 9 cooperates with the protrusion 8, the length of the detection component 1 is relatively stable, and the grading rod 5 sliding in the recovery chamber 4 of the handle 3 is operated in the same way, and the outer diameters of the grading rod 5 and the bottom rod 7 are reduced step by step by the same amount. After the length of the detection component 1 is determined, the user can rotate the shell 10 on the handle 3 to increase the distance between the top end of the shell 10 and the bottom end of the handle 3, thereby expanding the detection range of the detection component 1.

[0033] When detecting the width of the gap on the ground, the user inserts the detection component 1 into the gap. When the detection component 1 stops moving downward, that is, the two sides of the gap are completely in contact with the outer surface of the grading rod 5 or the bottom rod 7, the width of the gap can be known. After using the detection component 1, the user forcefully retracts the bottom rod 7 and the grading rod 5 into the retraction chamber 6 and the recovery chamber 4, rotates the shell 10 so that its bottom end is lower than the bottom end of the bottom rod 7, rotates the rotating rod 18 to separate it from the fixing rod 19, and the user rotates the cover plate 12 around the rotating shaft 11 to seal the bottom end of the shell 10, and at the same time bends the insertion rod 13 toward the center of the shell 10 so that it can be inserted into the card slot 14.
