In other embodiments, the main stand may be non-detachably mounted on the base, and the main stand is only arranged to reduce the carrying capacity of the fixed tool when the fixed tool is transferred because of the arrangement of the main stand.

In the above embodiment, four transition pieces are provided. In other embodiments, the number of the transition pieces may be increased or decreased according to actual situations, but at least two transition pieces are ensured, for example, three transition pieces, five transition pieces, and the like are ensured.

In the above embodiment, the avoidance passage is provided in the main stand. In other embodiments, the escape passage may also be provided on the secondary stand.

In the above embodiment, the main stand and the auxiliary stand are both plate-shaped structures. In other embodiments, the frame structure can be used as the main stand frame and the auxiliary stand frame without affecting the installation of the contact box, the insulating sleeve and the insulating support column.
