[0003] The prior art patent (patent name: 202320908859.7, patent name: a lightning arrester that is easy to install) realizes the quick disassembly and assembly function of the lightning arrester installed on the mounting bracket by setting a mounting groove, a fixing rod, a fixing frame, a threaded hole and a fixing shaft, thereby replacing the bolt installation method;

[0004] However, the above technical patent has the following defects: during installation, the fixing frames need to be flipped one by one so that the fixing grooves on the fixing frames are engaged with the fixing rods. When a large number of lightning arresters need to be installed, a large workload is also required. In addition, the fixing grooves and the fixing rods are in an engaged state, and the fixing rods can rotate freely. When vibration occurs, the fixing rods can easily separate from the fixing grooves, causing the lightning arresters to lose their limit positions, increasing the risk of the lightning arresters falling off. Therefore, an arrester that is easy to install is proposed to solve the above problems. Utility Model Content
