According to the replacement tool, a first clamp and a second clamp are connected through a transverse telescopic mechanism, a plug-in type bottle dragging frame is connected to the lower portion of the transverse telescopic mechanism through a connecting piece, and the whole replacement tool is formed. The calibers of the first clamp and the second clamp can be adjusted to be used for replacing strain insulators with different calibers, the first clamp and the second clamp are connected through the transverse telescopic mechanism, and the distance between the first clamp and the second clamp can be freely adjusted, so that the clamp is suitable for the strain insulators with different lengths, the replacement work of the strain insulators is facilitated, and the replacement efficiency of the strain insulators is improved. The universality is high, one replacing tool can be suitable for replacing different strain insulators, the tool does not need to be continuously replaced, and the maintenance ...
