[0002] As a key component of the rail transit system, the health of subway turnouts is directly related to the safety and efficiency of subway operations. In recent years, with the continuous expansion of urban rail transit networks and technological development, the technology for subway turnout rectification has also continued to improve. During turnout rectification operations, adjusting the track gauge is a key step. When adjusting the track gauge using the original rail support (which is usually installed on the outside of the base rail and enhances the overall stability of the track by connecting with the sleeper or other track components), the fixed supports on both sides of the rail support often fall off, seriously affecting operational efficiency. In order to improve operational efficiency, it is necessary to improve the original rail support and design a more convenient turnout gauge rectification tool. Summary of the Invention

[0003] The utility model provides a turnout gauge rectification tool for solving the technical problems existing in the known technology, which has the characteristics of being easy to use and not easy to fall off.
