摘要： A semi-trailer leg loading nut includes a screwed hole provided on a nut column and connecting two ends of the nut. Said nut is a two-layered structure formed of a top layer and an under layer or a three-layered structure formed of a top layer, an intermediate layer and an under layer. The outer outline of at least two layers of the nut is a square with the same cutting angle. The side length of the two layers of squares is equal. The outer outline projection of the two layers of squares overlap with each other along the column axis direction. The outer outline projection of the other layer is within the overlapped projection of the two layers along the column axis direction. A funneled oil cup or an oil groove is provided on the top layer of the nut and communicates with the screwed hole. A bottom of the under layer of the nut is plane and is pressed on a loading plate in a quadrate pipe to transfer load.
