Abstract (en)
A multi-mode one-way wrench includes a handle, a toothed wheel, two pawls and a switch. The handle is formed with a head and two grooves. The toothed wheel is rotationally placed in the head and formed with teeth. The first pawl is movably placed in the first groove for engagement with the toothed wheel. The second pawl is movably placed in the second groove for engagement with the toothed wheel when the first pawl is disengaged from the first pawl. The switch is operable for moving the second pawl between a first mode for engagement with the toothed wheel and a second mode kept from engagement with the toothed wheel. The first groove is biased from the second groove by an angle of 360°×(M+1/2)÷N, wherein N is an integer that represents the number of the teeth and M is any proper integer.
