[0026] Furthermore, in this embodiment, the compressed tension spring 405 drives the wedge-shaped clamping block 402 to move to its original position, so that the wedge-shaped clamping block 402 extends out of the sliding groove again and is correspondingly clamped with the clamping groove 403 opened in the installation groove, thereby restricting and fixing the lightning arrester 3, completing the fastening installation of the lightning arrester 3, and realizing the quick installation of the lightning arrester 3; by rotating the hand-twisting part 412 again, the wedge-shaped clamping block 402 retracts into the sliding groove again. At this time, the lightning arrester 3 has no connection with the installation box 1, so that the lightning arrester 3 can be removed, completing the quick disassembly of the lightning arrester 3. Embodiment 2

[0027] Refer to Figures 1 - 5, and on the basis of the first embodiment, it is further obtained that the winding part includes a winding wheel 409, a steel wire rope 407 is arranged on the surface of the winding wheel 409, and the steel wire rope 407 is wound around the surface of the winding wheel 409; a winding chamber is opened inside the fixed box 401, a rotating shaft 408 is arranged behind the winding wheel 409, the front of the rotating shaft 408 is fixedly connected to the back of the winding wheel 409, and the back of the rotating shaft 408 is rotatably connected to the inner wall of the winding chamber. A connecting shaft 410 is arranged in front of the winding wheel 409, and the back of the connecting shaft 410 is fixedly connected to the front of the winding wheel 409. A through hole is opened on the front of the fixed box 401, and the through hole is communicated with the winding chamber.

The two free ends of the steel wire rope 407 respectively penetrate through the winding chamber and are fixedly connected to the other connecting surface of the connecting block 406.

[0028] Furthermore, in this embodiment, by rotating the hand-twisting part 412, the hand-twisting part 412 drives the connecting shaft 410 to rotate, and the connecting shaft 410 drives the winding wheel 409 to rotate, so that the winding wheel 409 can wind the steel wire rope 407. The winding of the steel wire rope 407 will pull the wedge-shaped clamping block 402 to move into the chute, so that the wedge-shaped clamping block 402 can retract into the chute, thus facilitating the installation and disassembly of the lightning arrester 3.

[0029] During the actual operation process, when the lightning arrester 3 needs to be installed, first use bolts to fix the installation box 1 on the wall or the designated position by using the installation ears 2, and then rotate the two hand-twisting parts 412 on the front surface of the fixed box 401, so that the hand-twisting parts 412 drive the connecting shaft 410 to rotate, and the connecting shaft 410 drives the winding wheel 409 to rotate, so that the winding wheel 409 can wind the steel wire rope 407. The winding of the steel wire rope 407 will pull the wedge-shaped clamping block 402 to move into the chute, so that the wedge-shaped clamping block 402 can retract into the chute. At this time, the tension spring 405 is in a compressed state. Then, the lightning arrester 3 and the fixed box 401 are embedded into the installation groove of the installation box 1. At this time, release the hand-twisting part 412, so that the tension spring 405 is no longer extruded by external force, thereby releasing the elastic potential energy. The tension spring 405 will drive the wedge-shaped clamping block 402 to move back to its original position, so that the wedge-shaped clamping block 402 extends out of the chute again and is correspondingly clamped with the clamping groove 403 opened in the installation groove, so as to restrictively fix the lightning arrester 3 and complete the fastening installation of the lightning arrester 3, realizing the rapid installation of the lightning arrester 3;

[0030] When it is necessary to disassemble the lightning arrester 3, it is only necessary to rotate the hand-twisting part 412 again so that the wedge-shaped clamping block 402 retracts into the chute again. At this time, the lightning arrester 3 has no connection with the installation box 1, so that the lightning arrester 3 can be removed to complete the rapid disassembly of the lightning arrester 3.

[0031] Other parts not described in detail in the present utility model belong to the prior art and will not be elaborated here.

[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to the embodiments without departing from the principle and spirit of the present utility model.
