[0002] Power distribution is a link in the power system that is directly connected to users and distributes electric energy to users. The distribution switch belongs to an important part of the power distribution system. When the distribution switch is actually installed, it often needs to be hoisted by a hook in cooperation with a hoisting device. Since it is high-altitude operation, it is very inconvenient to adjust the position of the distribution switch after it is lifted to the specified height. Workers need to spend a lot of time for practical adjustment, and the installation is very difficult. Therefore, it is particularly important to design a lifting attachment for distribution switches to solve the above problems. Summary of the Invention
