Problems solved by technology

[0003] In the installation process of the lightning protection device in the prior art, it is necessary to use external screws and other fasteners to install the lightning protection device on the open-air electronic product. The installation and disassembly process is extremely cumbersome, time-consuming and laborious, and extremely inconvenient to use.
In addition, due to the unreasonable structural design of the existing lightning protector, when the existing lightning protector is damaged, the operator often cannot know that the lightning protector has been damaged, that is, the user cannot monitor whether the lightning protector is damaged, so it will Due to the damage of the lightning protector, the open-air electronic products are damaged by lightning strikes. If the operators are arranged to inspect the lightning protector regularly, the labor cost will also increase greatly.
