Abstract
Disclosed in the invention is a measuring instrument of bolt torque stress. The measuring instrument comprises a measuring instrument body, a bolt fixer, a torque stress sensor, and a force value display. The bolt fixer is installed in the measuring instrument body; and a thread slot channel is formed in the upper end of the bolt fixer, wherein the thread slot channel protrudes from the upper end of the bolt fixer. The bottom of the torque stress sensor is fixed on the measuring instrument body; and the upper end of the torque stress sensor is connected and fixed with the bolt fixer by a screw. The force value display is arranged on the outer end surface of the measuring instrument body; and the force value display and the torque stress sensor are connected by a lead. According to the technical scheme, the bolt can be installed and fixed on the measuring instrument body to carry out torque stress testing; and the testing result can be displayed directly by the force value display and recording data can be observed visually.
