| 2002 | Invention patented by Wen-Chang Wu on May 30th, 2002. Abstract: A do-it-yourself ceiling fan with a ceiling lamp has a ceiling frame and a guide head. A control rod can pull a confining inserting rod backwards so as to compress a spring. Thereby, the confining inserting rod is separated from a ceiling frame. The guide head inserts into an inserting seat of the ceiling frame, thereby, the ceiling fan being conductive to the ceiling lamp. By the resilient force of the spring, the resisting ring of the confining inserting rod restores to the original position to prevent the guide head from falling down. When it is desired to package, transfer or store the ceiling fan, the guide head with the ceiling lamp is pulled out from the ceiling fan. In assembly, it is only necessary to insert the guide head of the ceiling lamp into the ceiling frame of the ceiling fan without needing studs, and other tools. |
