[0004] In the above scheme, in order to adjust the height of the fixing bracket, the screw rod and the support rod are threadedly connected. However, in actual use, it is found that due to the setting of the screw rods on both sides, the screw rods on both sides need to be rotated simultaneously during adjustment. If the screw rods on both sides do not rotate synchronously, it will lead to failure to adjust, thereby affecting the efficiency of installation. Therefore, an adjustable fixing bracket for HVAC pipes is proposed. Utility Model Content
