Double ratchet structure and wrench

A double ratchet wrench comprising:

• a handle;
• a base disposed on the handle;
• a first directional member having a first pivot portion and a first claw, wherein the first claw is pivotally connected to the base via the first pivot portion;
• a second directional member having a second pivot portion and a second claw, wherein the second claw is pivotally connected to the base via the second pivot portion, and the second claw pivots oppositely to the first claw;
• two resetting members, wherein one of the resetting members is against and disposed between the first directional member and the base for protruding the first claw from the base, and the other resetting members is against and disposed between the second directional member and the base for protruding the second claw from the base;
• a choosing member coaxially and pivotally disposed on the base and covering the first directional member and the second directional member, the choosing member having a detent portion, wherein the detent portion is inwardly protruded from the choosing member to contact with the first claw or the second claw and to resist an elastic force applied to the first directional member or the second directional member thereby preventing the first claw or the second claw from being protruded from the base;
• a driving member coaxially disposed on the base and rotatably covering an outside of the first directional member and an outside of the second directional member, the driving member having an inner jaw portion for engaging with the first claw or the second claw;
• and
• a pivoting member coaxially disposed to the driving member and coaxially and pivotally disposed on the base, wherein the driving member is coaxially and pivotally disposed on the base via the pivoting member;
• wherein the choosing member comprises an annular portion having an inner surface, a top, a bottom and a rim portion which extends radially inwardly from the inner surface of the annular portion at a location between the too and the bottom of the annular portion;
• wherein the rim portion of the choosing member has a too surface which contacts the driving member, a bottom surface which contacts the base, and an innermost surface which defines the detent portion.
