Isolating switch and its operating mechanism

The invention relates to an isolating switch and an operating mechanism thereof in the field of high-voltage switches. The isolating switch comprises an isolating switch operating mechanism, wherein the isolating switch operating mechanism comprises a rotating shaft and an insulator mounting seat; a universal joint driving structure is arranged between the rotating shaft and the insulator mountingseat; and a limit structure for limiting the swing amplitude of the insulator mounting seat within the misalignment range between the insulator mounting seat and the rotating shaft is also provided.Compared with the prior art, while solving the problem of poor transmission effect between the actuating mechanism and the support insulator, the support insulator is positioned by a limit structure,and no other support structure is required for the support insulator, so that the manufacturing is simple, the use is convenient, and the cost is low. 本发明涉及高压开关领域中的隔离开关及其操动机构；隔离开关包括隔离开关操动机构，隔离开关操动机构包括转轴和绝缘子安装座，所述的转轴和绝缘子安装座之间设有万
