Abstract: A ratchet wrench comprises: a handle; a first member having an annular surface provided thereon with a plurality of teeth parallel to an axial direction thereof; a second member configured to rotate circumferentially with respect to the annular surface, the second member having at least two recesses arranged circumferentially around it; and at least two first drive transmission members disposed in the respective recesses of the second member, each of the first drive transmission members comprising at least one ratchet tooth, the first drive transmission members configured to be engaged with the teeth to transmit movement in a first direction between the first member and the second member, wherein each of the first drive transmission members is in a different engagement configuration with the teeth, wherein one of the first member and the second member is coupled to the handle and configured to be driven by the handle to rotate.

Abstract: A ratchet wrench comprises a handle defining a cavity including a plurality of teeth on an inner periphery thereof, a wheel, a biasing spring ring, and at least one tooth pawl mounted in recesses formed on the outer periphery of the wheel. The wheel is rotatably mounted inside the cavity and the pawls are biased by the spring ring to engage the plurality of teeth on the inner periphery of the cavity when rotated in a first direction, and to slide over the teeth engage the plurality of teeth on the inner periphery of the cavity when rotated in a direction opposite the first direction.
