Abstract

The utility model relates to an adjusting structure for a disc-shaped antenna support. Mainly, a rotary shaft pivoting to a motor is arranged in a rotating disk seat. A first worm and a second worm are sheathed on the rotary shaft, and a brake ring is arranged between the two worms. The brake ring is sheathed to an electromagnetic valve, and the first and the second worms are respectively engaged with a level driven gear fixedly locked on a base and a vertical driven gear fixedly locked on a disc-shaped antenna. When the motor is rotated, by the retention and the release of the electromagnetic valve, the level and the vertical driven gears are driven. Thus, an elevation angle and direction of the disc-shaped antenna are adjusted.
