The driving wrench has two ends of its shank 30 respectively provided with right-handed threads 31 and left-handed threads 32 on the surface. A crosswise insert hole 33, 34 is respectively bored at an outer side of the threads. The shank has two ends respectively protruding outward to form a positioning rod 35, 36 to be inserted in the insert hole 21 of one of the actuating discs 2. Two positioning sleeves 4, 5 are respectively combined with the threads at the two ends of the shank.
