In this embodiment, it is fixedly installed at the top of the support rod 3. Of course, it can also be designed to be hingedly installed at the top of the support rod 3, and then when the support rod 3 swings, it will drive the external equipment support 4 to swing together. The external equipment support 4 is used to support and fix the external equipment 6. The external equipment 6 can be a roof gift rack, a roof gift box, a roof photovoltaic panel, etc., without specific limitation. The external equipment support 4 can be fixed to the external equipment 6 by any fixing method such as screw connection, bonding or clamping, without specific limitation; Therefore, no matter it is a flat position on the roof or a position with an arc or an inclined surface, it is only necessary to fix the fixing plate 2 at the position, then swing the support rod 3 to a suitable angle, and adjust the support rod 3 to a suitable length, and then connect and fix the external equipment 6 through the external equipment support 4 at the top of the support rod 3. In this way, the external equipment 6 can be fixed at a position with an arc or an inclined surface, thereby making it more convenient to install the external equipment on the roof with an arc or inclined surface design.
