Abstract:
A reversible ratchet wrench includes a driving member received in a receiving space of a body, rotatable about a rotational axis relative to the body, and having an annular toothed portion. First and second pawls are aligned with each other along an axis parallel to the rotational axis and are alternatively disposed. The first and second pawls are received in a compartment in the body. One of the first and second pawls selectively meshes with the driving member. Each of the first and second pawls includes a ratcheting portion. The ratcheting portions selectively mesh with the annular toothed portion. A control member is pivotably received in the compartment. An end of the control member presses against the first and second pawls when the reversible ratchet wrench is switched between first and second positions. The control member can be actuated to move the first and second pawls.
