High-voltage protection insulating sleeve

The utility model relates to the technical field of insulating sleeves, and discloses a high-voltage protection insulating sleeve, which comprises an insulating sleeve body, a connecting mechanism is arranged at the end part of the insulating sleeve body, and the connecting mechanism comprises a first connecting sleeve, a first limiting ring, a blocking ring and a threaded sleeve shaft. The high-voltage protection insulating sleeve effectively solves the problems that in the actual use process, two or more sections of sleeves are connected in a hot melting mode, although the connection is firm in the mode, the sleeves cannot be conveniently and effectively disconnected when cables in the sleeves are overhauled or replaced, and the cables cannot be damaged. According to the sleeve, the problem that the sleeve is low in convenience in use due to the fact that the sleeve is arranged in the sleeve is solved, connection between the sleeves can be effectively completed in the whole operation process, and the connec
