Abstract: A detachable extension socket assembly includes an extension socket body and a frame. The frame is configured for fixing to an external component. The frame is provided with a perforating hole. The extension socket body is equipped with a position limiting part. The extension socket body at least partially passes through the perforating hole. The position limiting part abuts against the frame. In the present invention, the frame is configured for fixing to a table, and the extension socket body is detachably connected to the frame. Therefore, when the extension socket body is needed in other positions, the extension socket body can be separated from the frame, facilitating movement of the extension socket body, and solving the existing problems that installing the extension socket on a wooden table with screws can easily cause the table to crack around the screws and the installation is cumbersome.
