Abstract
A wrench includes: a main body having a tubular body and a head section, a rear end of the tubular body being formed with a first screwed section; a collapse mechanism disposed between the tubular body and the head section; a central rod disposed in the tubular body and formed with a first threaded section; a torque adjustment mechanism including at least one elastic member and an adjustment member, the adjustment member being formed with a second threaded section screwed with the first threaded section of the central rod; and a handle having a second screwed section screwed with the first screwed section of the tubular body. The handle is connected with the adjustment member. When rotating the handle, the adjustment is also rotated so that the torque of the wrench is easily adjustable.
