Detailed Description

The utility model is further described below with reference to examples. The following description is of some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The specific implementation mode is as follows:

the metal large Liang Yangji oxidation hanging tool comprises 1 hook 1,1 screw rod 2, a plurality of screws 3, a base body 4, a plurality of bolts 5, a plurality of pressing plates 6 and a plurality of bows 7.

The method is characterized in that: the anodic oxidation tool hook 1 is made of red copper; the screw 2, the base body 4 is made of aluminum alloy; the bolt 5, the pressing plate 6 and the shape frame 7 are made of splint bakelite; the screw 2 is made of stainless steel.

Firstly, 1 hook is connected with a base body by a screw, a bow-shaped frame is fixed on the base body by a screw, and the width of the bow-shaped frame is coordinated with the size of a girder. The pressing plate is connected by bolts, and is provided with an opening which is coordinated with the size of the matrix. The pressing plate is locally provided with a bulge which is contacted with the girder. The bow-shaped frame and the pressing plate are insulation objects. The height between the bow-shaped frame and the pressing plate is coordinated with the girder size. When the girder is used, the two sets of tools are matched for use, and the two ends of the girder form a height difference after being hung.
