[0017] The U-shaped frame 1 includes a bottom wall 102 and two side walls 101. A bottom plate 2 is arranged on the bottom wall 102 of each group of two U-shaped frames 1, and a detection device 5 is placed on the bottom plate 2. The upper ends of the two side walls 101 are provided with outward fixing plates 12, and the height of the side walls 101 is greater than the height of the detection device 5. The clamping device includes a clamping bolt 7 and an L-shaped clamping plate 6. The clamping plate 6 includes a horizontal plate 602 and a vertical plate 601. The horizontal plate 602 is arranged below the fixing plate 12 in parallel with the fixing plate 12. Two groups of third threaded holes are arranged on each vertical plate 601 at the same height. The third threaded holes are provided on the bottom of the two side walls 101. A limiting bolt 9 is provided in the hole, and a longitudinal strip hole is provided on the side wall 101 at a position corresponding to the limiting bolt 9.
