Reversible Ratchet Wrench with a Smaller Rotational Angle

摘要

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.

1. A reversible ratchet wrench with a smaller rotational angle comprising:
a body defining a rotational axis, with the body including a receiving space and a compartment intercommunicated with the receiving space, with the compartment located on a side of the receiving space in a radial direction perpendicular to the rotational axis; a driving member received in the receiving space of the body, with the driving member rotatable about the rotational axis relative to the body, with the driving member including an annular toothed portion surrounding the rotational axis; a ratcheting device including a first pawl and a second pawl, with the first pawl and the second pawl aligned with each other along an axis parallel to the rotational axis and alternatively disposed, with the first pawl and the second pawl received in the compartment, with one of the first pawl and the second pawl selectively meshed with the driving member, with the first pawl including a side facing the driving member and having a first ratcheting portion, with the second pawl including a side facing the driving member and having a second ratcheting portion, with the first ratcheting portion and the second ratcheting portion selectively meshed with the annular toothed portion of the driving member; a switching device defining a pivotal axis parallel to the rotational axis, with the pivotal axis spaced from the first pawl and the second pawl, with the switching device including a control member received in the compartment and pivotable about the pivotal axis, with an end of the control member pressing against the first pawl and the second pawl when the reversible ratchet wrench is switched between a first position and a second position, with the control member capable of moving the first pawl and the second pawl; and a push device mounted between the ratcheting device and the switching device, with the push device biasing the first pawl and the second pawl to mesh with the annular toothed portion.
