Abstract: A tool holder includes a receiving unit for receiving a plurality of hexagon wrenches. The receiving unit includes a first receiving seat and a second receiving seat. The first receiving seat and the second receiving seat are provided with a plurality of closed oval receiving holes having different dimensions and arranged in a row, so that the hexagon wrenches can be inserted into the receiving holes respectively. An axial end of each receiving hole is provided with a tapered inclined surface. Each receiving hole is provided with two symmetrical buckling portions for positioning the hexagon wrench. The hexagon wrench is positioned in the receiving seat by the buckling portions. After the hexagon wrench is rotated by 60 degrees, the hexagon wrench can be pushed to abut against the inclined surface with its engaging surfaces leaving the buckling portions.
