Abstract
A wrench includes a handle and a set of driving members to be selected to be coupled to the handle. Each of the driving members has a connecting portion complementary to the connecting portion of the handle. A coupling device is disposed at the connecting portion of the handle to detachably coupling the connecting portion of the driving member and the connecting portion of the handle. The coupling device forms a rotation axis; of the driving member, such that the driving member can rotate.
As a result, the driving members can be replaced quickly to the handle to meet the specific work.
As a result, the driving members can be replaced quickly to the handle to meet the specific work.
