The vertical pole 1 is provided with a connecting tenon plate 3 through welding. The connecting tenon plate 3 is provided with a connecting hole 31 and a protruding tenon 32; the end of the crossbar 2 is provided with a buckle knuckle 4, and the buckle knuckle 4 is provided with a transverse socket 41, a vertical socket 42 and a recessed knuckle. 43. The vertical socket 42 penetrates the transverse socket 41 and the mortise groove 43. The horizontal bar 2 forms a mortise and tenon structure by snapping the mortise head 4 and the connecting tenon plate 3. The latch 5 passes through the vertical socket 42 and the connecting hole 31 to snap the mortise joint. The head 4 is tightly locked with the connecting tenon plate 3 to achieve a tight connection between the vertical pole 1 and the horizontal pole 2.
