The outer peripheral surface of the directional column 20 is slidably mounted with a driving rack plate 18. The top of the driving rack plate 18 is fixedly connected to the driven rack plate 19 by screws. One side of the driving rack plate 18 is slidably mounted with two tooth blocks 24. Both sides of the tooth blocks 24 are fixedly connected to movable blocks 27 by screws. Both sides of the driving rack plate 18 are welded with fixed blocks 25. One side of the fixed block 25 is welded with a fixed rod 26. The movable block 27 is slidably mounted on the fixed rod On the outer peripheral surface of 26, the top of the protective box 7 is fixedly connected to the supporting plate 9 by screws, the top of the supporting plate 9 is slidably equipped with two clamping plates 10, and the detector body 11 is installed on the top of the supporting plate 9.
