A rectangular sleeve plate is fixedly connected to the output end of the electric push rod. Rectangular plates are slidably connected to both ends of the rectangular sleeve plate. Two rotating motors are fixedly connected to one side of the outer wall of the rectangular sleeve plate, and the two rotating motors are arranged opposite each other. A lead screw is fixedly connected to the output end of each of the two rotating motors. Two strip-shaped holes are opened on the outer wall of the rectangular sleeve plate near the rotating motors. The advantage of this utility model is that the mounting box is fixed below the supported object by several fixed holes. The electric push rod drives the rectangular sleeve plate to move up and down, raising the rectangular sleeve plate to support the supported object, thus completing the support work of this bracket. The installation method is convenient and the operation is simple, increasing efficiency.
