Claim:
1. A torque wrench capable of correcting torque, comprising: a tubular body; a head section positioned at a front end of the tubular body; a flexible rod pivotally disposed at the front end of the tubular body, the flexible rod being swingable, a rear end of the flexible rod being positioned in the tubular body, a front end of the flexible rod being fixedly connected with the head section; an abutment member and an elastic member disposed in the tubular body, the abutment member being positioned behind the flexible rod and movable within the tubular body; the elastic member elastically abutting against the abutment member; a trip mechanism disposed between the rear end of the flexible rod and the front end of the abutment member; the flexible rod and the abutment member being in contact with each other via the trip mechanism; an adjustment mechanism disposed at the rear end of the tubular body, the adjustment mechanism including a slide member disposed in the tubular body and movable within the tubular body; the adjustment mechanism being able to drive the slide member to move for adjusting the elastic force applied by the elastic member to the abutment member; a mechanical scale indication positioned on the tubular body for reading the set torque value of the wrench; at least one torque sensor disposed on one side of the flexible rod for detecting the strain of the flexible rod; and at least one display unit disposed on the tubular body for displaying the torque value detected by the torque sensor; wherein the tubular body is formed with a hollow section; a window is formed on the circumference of the tubular body; the mechanical scale indication including a scale plate, the scale plate being disposed on a circumference of the slide member and positioned between the window and the slide member; the scale plate being movable along with the slide member when it is mounted on the slide member; and a connection member being detachably fix the scale plate on the slide member, the connection member corresponding to the hollow section of the tubular body so that a user is able to unfasten the connection member for adjusting the position where the scale plate mounted on the slide member.
