By turning the third adjusting bolt, the supporting angle block rises and is clamped to the bottom of the bridge, thereby supporting the bridge, helping to adjust the heights of the new and old bridges to be consistent, further reducing the wear and tear on the bridge caused by vehicle driving, and overcoming the deficiencies of the prior art.

The lower end faces of the two bridges are fixed with seat plates, and the lower end faces of the two seat plates are welded with a clamping seat. The vertical sections on both sides of the U-shaped limit plate are respectively inserted in the middle part of the two seat plates, and adjustment frames are installed at both ends of the upper end face of the U-shaped support plate.

[0008] As a further solution of the present invention: both ends of the top horizontal section of the rectangular frame are screwed with third adjusting bolts, and the upper ends of the two third adjusting bolts are rotatably connected to the supporting angle blocks through bearings.

[0009] As a further solution of the present invention: both ends of the horizontal section of the U-shaped support plate are connected to U-shaped guide rods, and two sliders are symmetrically fixed to the lower end surfaces of the two rectangular frames, and the sliders on the two rectangular frames are respectively slidably sleeved on the two U-shaped guide rods.

[0010] As a further solution of the present invention: the supporting corner block is L-shaped, and the supporting corner block is clamped with the bridge at the corner at the bottom end of the bridge.
