ABSTRACT:
A wrench with visually recognizable mechanism comprises a main body as a handle and wrench heads that are separately connected to two ends of the main body. The wrench heads are capable of tightening or loosening fastening parts with corresponding dimensions. The visually recognizable mechanisms are provided on the main body or the wrench heads, whose appearances assist in distinguishing classification and properties of the wrenches.
