Furthermore, the support is L-shaped structure, and includes vertical end and horizontal end, and wherein the top of vertical end is connected with the bottom of round pin axle, and the bottom of vertical end and the one end mutually perpendicular of horizontal end are connected.

Furthermore, the base is of a rectangular sheet structure and is integrally arranged on the upper surface of the horizontal end of the support, the vertical end of the support is vertical to the plane of the base, and the horizontal end of the support is positioned at the central axis of the base; the surface of the base is provided with anti-skid grains.

Compared with the prior art, the utility model has the advantages that:

1) the method has the advantages of high adjustment precision, high efficiency, safety and effectiveness, can avoid finish paint damage caused by flange adjustment, and effectively reduces maintenance cost;

2) the tool is simple in structure, easy to manufacture, suitable for portal frame assembling occasions of different models and suitable for large-area popularization and use.
