[0027] Specifically, when the height of the upper beam 14 needs to be changed, the height of the connecting plate 13 and the connecting plate 2 15 is manually adjusted, and then the bolt 19 is tightened to lock the height of the connecting plate 13 and the connecting plate 2 15, thereby enabling detection of larger materials.

[0028] In one embodiment, a locking mechanism is provided on the connecting plate 13 , and the locking mechanism is used to fix the connecting plate 13 and the upper beam 14 together.

[0029] In one embodiment, the top end of the connecting plate 13 is arc-shaped to ensure that the connecting plate 13 can swing smoothly. A cavity 26 is opened on the side of the connecting plate 13, and a detachable closing plate 33 is installed on the front side of the cavity 26. The closing plate 33 is used to seal the cavity 26.
