Electric-adjustment antenna transmission device

The invention discloses an electric-adjustment antenna transmission device. The device is characterized by including a position-selecting transmission component connected with an electric-adjustment controller, screw rod transmission components and pulling rods. The screw rod transmission components include transmission screw rods and transmission screw rod gears disposed on the transmission screwrods. The screw rod transmission components are connected with phase shifters through the pulling rods. The position-selecting transmission component includes position-selecting connection shaft sleeves, a front chamber body, a position-selecting input shaft, a transmission connection shaft sleeve, a transmission input shaft, idler wheels, a transmission driven-wheel, a position-selecting memberand a rear chamber body. The electric-adjustment controller is connected with the position-selecting input shaft through the position-selecting connection shaft sleeves. Position-selecting input shaftgears are disposed at the
