Abstract

A measuring device for measuring the torque of a torsion spring, includes a base, an electronic scale secured to the base, a supporting plate fixed to the base, and a holding mechanism slidably secured to the supporting plate. The holding mechanism includes a screw slidably secured to the supporting plate, two nuts engaging with the screw and arranged at opposite sides of the screw, and a holding portion for holding the torsion spring. The nuts are operated to adjust the height of the screw relative to the supporting plate, to drive the torsion spring to depress the electronic scale. The electronic scale displays a weight value for calculating the torque of the torsion spring when depressed by the torsion spring.
