Power sockets and plugs vary in appearance, grade, size and type depending on the country and region. Each country has its own government-developed standards. A power plug is also called a power cord plug. When a power plug is not practical, it is usually placed around an electrical appliance without any protective measures. Random placement may cause people to step on it, and dust may adhere to the surface, and moisture and water droplets may accumulate due to the humid environment, which may affect the subsequent use of the power plug.

[0003] Therefore, it is necessary to provide a new power plug protection device to solve the above-mentioned technical problems. Utility Model Content
