Abstract

The invention discloses a measuring structure of a hand tool. A fillister is set between a holding portion and a pulling portion of a wrench main portion, and a gap portion is formed at the front end and the rear end of the fillister. By the design of the gap portion, the fillister becomes a stress concentration position. Therefore, a strain gauge which is set in the fillister having results of deformation easily. When the strain gauge is deformed, the changing of the resistance value is calculated by an integration element and convert to a torsion value that the tool is borne, and it displays the torsion value for a user's reference. By the setting of the gap portion, the integration element can detect the torsion value sensitively by the strain gauge. It prevents from the inaccuracy between the real torsion value and the measured torsion value to cause unnecessary damage or breakdown when using it.
