ABSTRACT:
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.
