A gear wrench allowing easy force application, having: a head, formed with a receiving compartment thereon for receiving a gear ring, the head extending along a first plane; a tail, extending along a second plane; and a neck, provided between and integrally formed with the head and the tail; characterized in that: the first plane is parallel to the second plane, and the neck obliquely extends from the head towards the tail to form a height difference between thee head and the tail. As such, the vertical component of force may be eliminated or minimized so as to effectively reduce occupational hazards; the horizontal component of force may also be increased such that the operator only requires a lower force to effectively tighten or loosen up a fastener.

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.
