[0033] The first component 100 is directly integrated with support column 600, and the top has the mounting steel plate fixed on the top surface of support column 600, the connecting plate 110 is vertically provided on the mounting steel plate, the connecting plate 110 extends out of the top of the first component 100, and the connecting plate 110 is vertically arranged with the mounting steel plate.
[0034] The second component 200 has the connecting groove 210 inserted with the connecting plate 110, specifically when installing, the connecting plate 110 is inserted into the connecting groove 210, i.e. the connecting groove 210 is set on the outside of the connecting plate 110.
[0035] The third component 300 is provided with the clamping groove 310 for the connecting plate 110 to pass through on at least one side wall. The height of the clamping groove 310 is matched with the height of the connecting groove 210, and the width of the clamping groove 310 is matched with the outside wall thickness of the connecting plate 110, so that the connecting plate 100 is inserted into the connecting groove 210 and is stably connected with the connecting groove 210.
