Detailed Embodiment

[0020] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model includes an insulating board 2 installed on the iron cross arm 1, a wire tool switch 3 installed at one end of the insulating board 2, a lightning arrester 4 installed below the insulating board 2, and an insulating gripper for quickly clamping on the lightning arrester 4. A suspension bracket 11 and a disconnector 5 are arranged at the right end of the lightning arrester 4. A suspension pin 12 is arranged on the suspension bracket 11. A hook 10 for cooperating with the suspension pin 12 is arranged on the insulating board 2. A channel steel 7 is arranged on the bottom surface of the insulating board 2. A support plate 8 for supporting the left end of the lightning arrester 4 is fixedly installed on the web of the channel steel 7. A groove 8-1 matching the left end of the lightning arrester 4 is arranged on the side surface of the support plate 8 away from the web of the channel steel 7. A compression spring 9 is arranged between the web of the channel steel 7 and the support plate 8.

[0021] In this embodiment, by arranging the insulating board 2 on the iron cross arm 1 and installing both the wire tool switch 3 and the lightning arrester 4 on the insulating board 2, the insulating board 2 can play a role in supporting both the wire tool switch 3 and the lightning arrester 4 simultaneously, without the need to use multiple expensive insulating cross arms. The insulating board 2 has high strength and good corrosion resistance, which can improve the safety and stability of the installation of the wire tool switch 3 and the lightning arrester 4, and has good economy.

[0022] In this embodiment, by arranging the channel steel 7 on the bottom surface of the insulating board 2, fixedly installing the support plate 8 on the web of the channel steel 7, and arranging a compression spring 9 between the web of the channel steel 7 and the support plate 8. During actual installation, there are bosses on the web of the channel steel 7, and the groove 8-1 appears as a protrusion on the side surface close to the web of the channel steel 7. The two ends of the compression spring 9 are respectively sleeved on the boss and the protrusion. Therefore, when the suspension pin 12 is installed on the hook 10, under the action of the compression spring 9, the end of the left end of the lightning arrester 4 can always be clamped in the groove 8-1 of the support plate 8, thereby realizing the connection between the left end of the lightning arrester 4 and the support plate 8.

[0023] In this embodiment, by arranging an insulating gripper for quickly clamping on the lightning arrester 4, during actual use, the operator can remove the lightning arrester 4 live while standing on the utility pole without power-off operation, which will not affect the normal power consumption needs of residents.
