Abstract: A tool box includes a cover mounted to a base which receives a receiving member, an extension rod, a collapsible member and a light means therein which is actuated by a switch member disposed to the box. The receiving member receives a plurality of bits and is pivotally disposed to the base member, a spring member is disposed between the base member and an underside of the receiving member to pop up the receiving member when the cover is opened. The extension rod can be inserted into a polygonal passage defined in an end of the box so as to connect with a bit. The collapsible member has a magnetic member disposed to a distal end thereof so as to magnetically adhere bits.
