ABSTRACT:
A hexagon spanner handle of the present invention includes a handle whose three edges are inwardly concaved respectively so as to form three shaft-like bodies at three triangle points. The handle has plural hexagonal apertures in different sizes arranged along the three shaft-like bodies. One plane surface of the handle has three position-limiting slots which are respectively located in three shaft-like bodies and outwardly extended along the shaft-like body and are communicating with the hexagonal apertures. The bottom of each position-limiting slot has plural indentations in different widths, and a magnetic body is located at the end of the position-limiting slot. Thereby, each hexagonal aperture can be inserted by the short leg of corresponding hexagon spanner, and the position-limiting slot can receive the long leg of the hexagon spanner with the magnetic body attracts thereof for fixing, so that the handle can be assembled with hexagon spanners in different standards.
