A positioning groove 23 is provided on the surface of the connecting plate 22, and a first movable groove 24 is provided on the inner side of the connecting plate 22. A pull rod 25 is movably connected to the inner side of the first movable groove 24, and an insert block 26 is fixedly connected to the surface of the pull rod 25. A slot 27 is provided on the surface of the positioning block 21. The pull rod 25 is movable on the inner side of the first movable groove 24 to realize the insertion and separation of the insert block 26 and the slot 27, thereby facilitating the fixing and disassembly of the mounting sleeve 2 and the connecting plate 22, so that the installation and removal of the disconnector are relatively convenient, and there is no need to repeatedly operate the bolts.

[0024] Furthermore, the installation mechanism also includes a fixing rod 28, which is fixedly connected to the inner wall of the first movable groove 24, and the inner wall of the first movable groove 24 is fixedly connected with a spring 29. Through the setting of the fixing rod 28, it is convenient for the pull rod 25 to move stably on the inner side of the first movable groove 24, thereby realizing the insertion and separation of the plug block 26 and the slot 27.

[0025] Furthermore, the positioning blocks 21 are formed into four groups and fixedly connected to the mounting sleeve 2, and the positioning grooves 23 are formed into four groups and opened on the upper surface of the connecting plate 22. By setting the positioning blocks 21 and opening the positioning grooves 23, the mounting sleeve 2 can be positioned on the pole 1, thereby avoiding misalignment during installation and enabling the mounting base 11 to be better installed and fixed.

[0026] Furthermore, the pull rod 25 and the fixed rod 28 are movably connected, one end of the spring 29 is fixedly connected to the first movable groove 24, and the other end of the spring 29 is fixedly connected to the pull rod 25.

At this time, the spring 29 is in a contracted state, and then the positioning block 21 on the installation sleeve 2 is positioned and inserted into the positioning groove 23 on the connecting plate 22, and then the pull rod 25 is released. The pull rod 25 will be reset under the rebound action of the spring 29, and then the plug block 26 and the slot 27 can be plugged in, and the installation sleeve 2 can be fixed, so that the installation can be completed; when maintenance and removal are required, the pull rod 25 is pulled to separate the plug block 26 and the slot 27, and the positioning block 21 can be released;
