Through the third stopper that is equipped with, realized the spacing function of buckle, avoid it to break away from and accomodate the groove, improved this structural stability.

In a further technical scheme, the buckle and the clamping groove are provided with a plurality of buckles and clamping grooves, and are respectively and correspondingly arranged.

Because the buckle and the draw-in groove are equipped with a plurality of, make two casings more stable after the installation, be difficult for appearing the crack, improved the life of this structure.

The beneficial effects of the utility model are as follows:

1. by adopting the lightning arrester with the composite shell structure, the installation of the two shells is realized through the plugboard, the storage groove, the spring, the buckle and the clamping groove, the operation is simple and convenient, the convenience is provided for maintenance personnel, the problem that part of defects exist in the existing lightning arrester is solved, most of lightning arrester bodies and the shells are integral, the disassembly and the installation are troublesome, and when the lightning arrester bodies are required to be overhauled, great difficulty is brought to the maintenance personnel.

2. By adopting the lightning arrester with the composite shell structure, the lightning arrester body and the shell are fixed through the first limiting block and the second limiting block, and the stability after installation is improved.
