An antenna detaching-proof rotation idling device having a metal connector with an electroplated inner bore to lock on an antenna-connecting seat of a mobile phone. The connector has its threaded section extended down from its main disk body. An insulating piece is mounted in the inner bore of the connector in a tight connecting mode. A central guiding needle is installed in a central bore in the insulating piece in a loose connecting mode. The top end of the needle gets above the disk body of the connector to mount an electric circuit board. The bottom of the needle is exposed a given length under the connector. The portion of the connector above the disk body is ejection shaped into a sleeve. The sleeve, the electric circuit board and the needle are connected and moved together. The connector being plated with a layer of white chrome, after the sleeve is mounted, it will be rotation idling when being rotated. Thus bad signal receiving and damage of the electric circuit board by users' random rotating can be prevented.
