Insulating sheath of isolating switch

The invention relates to the field of isolating switch insulating sheaths, in particular to an isolating switch insulating sheath which comprises a first insulating sheath body installed on an isolating switch, a switch through hole and a wire through hole are formed in the first insulating sheath body, the isolating switch penetrates through the switch through hole, a wire penetrates through the wire through hole, and the isolating switch penetrates through the wire through hole. The switch through hole and the wire through hole are provided with a plurality of snap fasteners, the snap fasteners are used for locking the switch through hole and the wire through hole, and the middle of the first insulating sheath is of a telescopic structure. The first insulating sheath integrates all sheath functions of an existing isolating switch into a whole, the first insulating sheath has the advantages of being capable of comprehensively shielding the isolating switch and saving time and labor in installation, and the m
