Indoor overhead water supply and drainage pipeline positioning support

The indoor overhead water supply and drainage pipeline positioning support comprises a top seat, supporting stand columns are fixedly connected to the two sides of the upper surface of the top seat, a first mounting plate is fixedly connected to the top ends of the supporting stand columns, and a two-way screw is rotationally connected to the inner side wall of the first mounting plate; and one end of the two-way screw rod is fixedly connected with a rocker. According to the indoor overhead water supply and drainage pipeline positioning support, through the arrangement of the bidirectional screw, the first sliding blocks, the supporting arms, the second sliding blocks, the supporting rod and the base, the bidirectional screw rotates, the two first sliding blocks on the outer surface of the bidirectional screw get close to each other or are separated, the supporting arms drive the second sliding blocks at the bottom ends to move on the outer surface of the supporting rod, and the height of the base is adjusted
