Combination Including a Ratchet Wrench and a Driving Member

摘要

A combination includes a ratchet wrench and a driving member. The ratchet wrench includes a body and a ratchet wheel mounted in the body and rotatable relative to the body about a rotational axis. A driving hole extends through from a side through the other side of the body along the rotational axis and includes an inner periphery having a plurality of abutment surfaces. A corner is formed between each two adjacent abutment surfaces. At least one limiting portion protrudes from the inner periphery of the driving hole in a radial direction perpendicular to the rotational axis. The driving member includes at least one evasive portion and is coupled to the driving hole. The driving member is movable between a first coupling position and a second coupling position along the rotational axis when the at least one evasive portion is aligned with the at least one limiting portion.

1. A combination comprising a ratchet wrench and a driving member, with the ratchet wrench including:
a body; and a ratchet wheel mounted in the body and rotatable about a rotational axis relative to the body, with the ratchet wheel including a first side and a second side spaced from the first side along the rotational axis, with the ratchet wheel further including a driving hole extending from the first side through the second side, with the driving hole including an inner periphery having a plurality of abutment surfaces contiguous to each other and arranged along a circumferential direction about the rotational axis, with a first corner formed between each two adjacent abutment surfaces of the driving hole, with at least one limiting portion protruding from the inner periphery of the driving hole in a radial direction perpendicular to the rotational axis and formed in at least one of the first corners, with the driving member including a first end, a second end, and a connecting section, with the connecting section including an outer periphery having a plurality of abutment faces contiguous to each other, with a second corner formed between each two adjacent abutment faces of the connecting section, with the connecting section including at least one evasive portion between two adjacent abutment faces, with the at least one evasive portion including an evasive face having two sides respectively connected to the two adjacent abutment faces, with the connecting section adapted to be coupled with the driving hole of the ratchet wheel by extending along the rotational axis, with the plurality of abutment faces of the connecting section abutting the plurality of abutment surfaces of the driving hole, and with the connecting section located in one of a first coupling position and a second coupling position relative to the ratchet wheel, wherein when the driving member is in the first coupling position, the first end of the driving member abuts the at least one limiting portion of the ratchet wheel, and the at least one evasive portion is not aligned with the at least one limiting portion, and wherein when the driving member is in the second coupling position, the first end and the second end of the driving member are located on two sides of the ratchet wheel along the rotational axis, and the at least one evasive portion is aligned with the at least one limiting portion.
