[0025] In this embodiment: when in use, the welded steel pipe can be passed through the vertical plate 4 and the fixing seat 1, and can be inspected after being inserted and fixed. Before the inspection, the height of the guide wheel 36 and the probe 37 can be adjusted, and the operation of the hydraulic cylinder 34 will drive the adjustment plate 35 to move downward.
