The invention provides a multi-mode satellite antenna pan-tilt control device, comprising an antenna pan-tilt, a device box body is mounted on the side of the antenna pan-tilt, a plug socket is embedded in the inner side of the device box body, and a rubber strip is embedded in the inner side of the socket socket , The inner side of the socket is provided with a transmission mechanism that can automatically limit the position of the plug. The transmission mechanism includes a lever frame, a sliding frame, a swing frame, a track, a rotating shaft, a sealing frame, a baffle and a telescopic rod. When the turntable swings, the extension ring is driven to move Swing horizontally, the bump drives the limiter to swing as a whole through the tooth piece, so that the limiter can swing around the through shaft. When the limiter swings, it drives the limiter to limit and fix the two ends of the plug, so that the The device can automatically limit the plug when the plug is embedded inside, to avoid the situation that the plug is easy to fall off after long-term use, and can use the limiter as a whole to prevent dust from entering the interior of the socket through the gap between the plug and the socket. .
