However, the seismic support and hanger for ventilation and air conditioning water system, while solving the problem, has the following defects:

[0004] The clamp and the anti-seismic mechanism are set at a fixed position on the support rod, and the buffer mechanism is also located at a fixed position on the support rod. Therefore, when drilling a hole on the top of the wall for fixing the hinge seat, if the drilling is offset, the position of the clamp will not correspond to the position of the pipeline, resulting in the inability to connect to the pipeline later. Therefore, high drilling accuracy is required. If the drilling is misplaced, re-drilling is required, which will directly affect the construction efficiency. Utility Model Content
