[0002] A lightning tower is a common iron tower-type lightning protection device. A lightning tower built with a steel structure can have a more stable effect. High-strength bolts are made of high-strength steel, or bolts that require a larger pre-tightening force are generally used together with bolt caps, also known as nuts.

[0003] Lightning towers are mainly used for lightning protection projects of various buildings, especially in refineries, gas stations, chemical plants, coal mines, explosives depots and other places. Due to the height of lightning towers, they are generally required to be fastened with high-strength bolts to achieve the effect of stable fixation of the tower. When the bolts are used for a long time, the bolt caps need to be replaced in time to prevent them from being damaged or deformed after long-term use, affecting the stability of the connection. However, the existing replacement methods are to rotate the bolt caps from the side, which is inconvenient to use at high places on the lightning tower, and it will be inconvenient for the staff to exert force to rotate, affecting the convenience of disassembly and replacement of the bolt caps.
