A socket drive head structure includes a drive head, an actuating rod, an actuating knob, a positioning ball, and an elastic member. Thus, the socket drive head structure is mounted on and detached from a socket rapidly, easily and conveniently, so that the user needs not to exert a large force to remove the socket from the socket drive head structure. Further, the outer threaded portion of the actuating knob is directly screwed into and locked in the threaded knob hole of the actuating rod, so that the actuating knob is actually fixed on the actuating rod easily and conveniently, thereby facilitating assembly and maintenance of the socket drive head structure.
