The lower end of the anti-seismic mounting rod 2 is fixed to the support crossbeam 3. The position of the connecting side plate 8 is adjusted through the adjustment mechanism to meet the quantity requirements of the water supply and drainage pipeline body 26. When the position of the connecting side plate 8 is adjusted, the main support mechanism adjusts simultaneously with the connecting side plate 8.
