Abstract
A wrench combination includes a wrench and a drive member. An inner protrusion is formed on a polygonal inner periphery of a box end of the wrench. The drive member includes an engaging portion removably mounted in the box end and engaged with the polygonal inner periphery, with an end of the drive member being located outside the box end. The engaging portion includes a retaining section. A retaining member is mounted on the drive member. Each of the retaining section and the retaining member has an outer diameter greater than a diameter of a hole delimited by the inner protrusion. The retaining section and the retaining member respectively abut against two end faces of the inner protrusion to position the drive member. The retaining member is compressible to be smaller than the diameter of the hole delimited by the inner protrusion.
