Abstract
A one-way torque tool includes a head, a rotor placed in the head, a number of ratchets formed on the head, two pawls pivotally connected to the rotor and detachably engaged with the ratchets. The ratchets are separated from one another by a first angle α identical to 360 degrees divided by the number of the ratchets. The pawls are separated from each other by a second angle β identical to a multiple of the first angle α plus a third angle θ that is smaller than the first angle α.
