Zusammenfassung:	The utility model discloses a manhole isolator. The manhole isolator comprises a first strip plate, a second strip plate, a disc, a bolt and a nut. The bolt penetrates through the middle of the first strip plate, the middle of the second strip plate and the center of the disc, and is fixedly connected with the middle of the first strip plate, the middle of the second strip plate and the center of the disc through the nut. Through holes coinciding with each other are formed in the bolt and the nut. Installation holes are formed in the two ends of the first strip plate respectively. The manhole isolator is reasonable in design, simple in structure, easy to manufacture and safe and convenient to use. The phenomenon that external maintainers or non-specialized people enter a manhole privately in the state without any protection can be effectively prevented, and smooth and safe production is ensured.
