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

Abstract: A wrench includes a driving head, an axle hole formed at an end of the driving head, an accommodating portion disposed in the axle hole for accommodating pawls, a control ring contained in the axle hole and having an end extended out of the axle hole and coupled to a wrench handle, and a ratchet section and a smooth section defined on an external periphery of the control ring, and the ratchet section is provided for latching the pawls to define a fixed state of latching the wrench handle with the driving head and can be rotated into a secured status, and the smooth section is provided for pushing the pawls to release the fixed state of latching the control ring, so as to allow the wrench handle to be turned with respect to the driving head for a quick rotation.

Abstract: A device for switching wrenching direction of a ratchet wheel of a ratchet tool. A ratchet wheel and a pawl are accommodated in a receiving cavity of the main body of the ratchet tool. The receiving cavity is covered by a cover board for hindering the ratchet wheel and the pawl from dropping out of the receiving cavity. A shift member is disposed on the pawl. The cover board is formed with a locating slot corresponding to the shift member. The locating slot has a first locating section and a second locating section. After the shift member is shifted to move the pawl and switch the wrenching direction, the shift member can be selectively located in the first locating section or the second locating section.
