Abstract (en)
A one-way torque tool includes a head (21), a rotor (30) placed in the head, a number of ratchets (51) formed on the head, two pawls (60) pivotally connected to the rotor and detachably engaged with the ratchets. The ratchets are separated from one another by a first angle (±) identical to 360 degrees divided by the number of the ratchets. The pawls are separated from each other by a second angle (²) identical to a multiple of the first angle plus a third angle (¸) that is smaller than the first angle (±).
