A
cantilever insulator sheath with an anti-bird function comprises a sheath body, the top of the sheath body is communicated with a
cantilever sleeve, an anti-bird umbrella skirt is arranged between the sheath body and the
cantilever sleeve, and the bottom of the sheath body is communicated with an insulator umbrella sleeve connecting
pipe. The sheath body, the cantilever sleeve, the anti-bird umbrella skirt and the insulator umbrella sleeve connecting
pipe are all made of
soft materials, a first through groove is formed in one side of the sheath body, a second through groove is formed in the position, corresponding to the first through groove, of the cantilever sleeve, a third through groove is formed in the position, corresponding to the first through groove, of the anti-bird umbrella skirt, and the third through groove is communicated with the third through groove. A fourth through groove is formed in the position, corresponding to the first through groove, of the insulator umbrella cover connecting
pipe, and the first through groove, the second through groove, the third through groove and the fourth through groove can be fixed through a fixing device. According to the utility model, the anti-bird umbrella skirts, the sheath body and the cantilever sleeve are integrally arranged, so that integral installation can be realized, the operation is simple, and the installation efficiency is effectively improved.
