A tool fixing structure includes a snap ring, a fixing socket, an elastic member, a fixing rod, an outer socket, and a pressing socket. In such a manner, the screwdriver head is mounted on and detached from the tool fixing structure rapidly, easily and conveniently, thereby facilitating replacement of the screwdriver head, and thereby facilitating the user operating the screwdriver head. In addition, the pressing socket is modularized, and may be replaced according to the requirements, thereby enhancing the versatility of the tool fixing structure. Further, the snap ring, the outer socket and the pressing socket are made of an aluminum material, thereby decreasing the weight of the tool fixing structure.
