A quick-turn wrench includes a driving head 11 with an axle hole 13. One side of the axle hole 13 has a claw 15. A ratchet ring 21 is accommodated in the axle hole 13. One end of the ratchet ring 21 extends outside the axle hole 13 and connects to a wrench handle 31. The ratchet ring 21 is surrounded by a ratchet part 23 that correspondingly engages the claw 15. A transmission rod 41 is inserted into the ratchet ring 21, with one end having a transmission part 43. A bottom plate 51 is disposed at the bottom of the axle hole 13. The end surface of the bottom plate 51 facing the axle hole 13 has a sliding groove 52. A pushing element 53 is disposed in the sliding groove 52 corresponding to the claw 15. The transmission part 43 of the transmission rod 41 connects to the pushing element 53. As the transmission rod 41 rotates, the pushing element 53 is driven to push the claw 15 to release the fixing state between the claw 15 and the ratchet ring 21.
