Preferably, the bearing comprises an inner ring and an outer ring, the protrusions overlap the outer ring, and the inner ring overlaps the lower gasket.

Preferably, the lower gasket is disposed between the aluminum plate and the cross beam.

Compared with the prior art, the utility model has the advantages and positive effects that,

according to the utility model, the bearing is positioned through the bolts, the aluminum plate rotates by taking the bearing as a fulcrum, the aluminum plate is not required to be dismounted through dismounting the bolts, the sliding of the front supporting plate close to the iron can be prevented from being influenced by only rotating the aluminum plate, and the aluminum plate rotates by taking the bearing as a fulcrum, so that the friction force is small, and the aluminum plate is convenient to rotate. The bolt compresses tightly the upper gasket, and then presses the bulge on the bearing, has realized location aluminum plate. The utility model has simple structure, easy manufacture and suitability for popularization and use.
