1. A wrench easily adjustable in torque, comprising:
a main body having a tubular body, an outer circumference of a rear end of the tubular body being formed with a first screwed section, a head section being positioned at a front end of the tubular body; a collapse mechanism disposed between the tubular body and the head section, when the wrenching force of the wrench reaches a set torque, the collapse mechanism is collapsible; a central rod, a rear end of the central rod being formed with a first threaded section, the central rod being disposed in the tubular body of the main body, the head section being pivotally connected with a front end of the central rod; a torque adjustment mechanism including at least one elastic member and an adjustment member; a front end of the adjustment member being formed with a threaded hole, the thread of the threaded hole serving as a second threaded section, the second threaded section being screwed with the first threaded section of the central rod, whereby when the adjustment member is rotated, the adjustment member is also moved in an axial direction of the central rod; the elastic member being disposed in the tubular body, two ends of the elastic member respectively abutting against an inner side of the tubular body and the adjustment member; and a handle, a front end of the handle being inward recessed to form a screwed hole having a second screwed section, the second screwed section being screwed with the first screwed section of the tubular body, whereby when the handle is rotated, the handle is also moved in an axial direction of the tubular body, the handle being connected with the adjustment member; and the pitches of the first screwed section of the tubular body, the second screwed section of the handle, the first threaded section of the central rod and the second threaded section of the adjustment member being equal to each other. |
