[0033] There are two hanging holes 126, two positioning holes 127, and two fixing pins 128; the fixing pins are installed on both sides of the hook respectively. Two fixing pins 128 are installed on both sides of the hook to ensure a more secure connection between the hanging plate 124 and the hanging fixing block 121, reducing loosening and slippage that may occur due to single-point fixing. The two fixing pins 128 can better distribute the stress generated during installation and use, making the force on each part of the hanging assembly 120 more even, improving the overall stability and reliability. The structure of the two fixing pins 128 and the corresponding hanging holes 126 and positioning holes 127 provides multi-point support, enhancing the structural strength of the hanging assembly 120 and making it more robust when subjected to external impact. Multiple fixing points can effectively prevent the hanging plate 124 from deforming due to uneven force during long-term use, extending the service life of the socket. The structure of the two fixing pins 128 and the corresponding hanging holes 126 and positioning holes 127 allows users to quickly align the components during installation, ensuring accurate connection between the hanging plate 124 and the hanging fixing block 121. If the socket needs to be moved or disassembled, the hanging plate 124 can be easily removed simply by taking out the two fixing pins 128, making the operation simple and convenient.

[0034] Please refer to Figures 1 to 3The power distribution socket structure with overload protection also includes a power cord 130 disposed on the upper cover 20, a plug 140 connected to the free end of the power cord 130, and a cable tie 150 installed on the power cord 130. The plug 140 connects directly to the free end of the power cord 130, allowing users to quickly insert the power cord 130 into a wall socket without additional connectors, simplifying installation. If the plug 140 is damaged, users can easily replace it without replacing the entire power cord 130, reducing costs. The cable tie 150 keeps the power cord 130 neatly organized, preventing it from becoming tangled and knotted during use. The cable tie 150's structure makes the power cord 130 look cleaner and more aesthetically pleasing, enhancing the overall visual appeal and making it suitable for homes, offices, and other locations. The cable tie 150 also reduces damage to the power cord 130 caused by dragging, stepping on, or contact with sharp objects, extending its lifespan. A neatly organized power cord 130 reduces the risk of tripping, especially for families with children or pets, increasing safety. Furthermore, the organized management of the power cord 130 reduces the risk of fire caused by short circuits or overheating, improving overall safety.

[0035] The power distribution socket with overload protection also includes an indicator light 160 located on the upper cover 20. The indicator light 160 displays the real-time operating status of the power distribution socket, such as whether the power is on and whether current is flowing, allowing users to easily understand the socket's operation.
