The utility model discloses a survivor of a murder attempt torque wrench, including spanner head, elastic torsion pole, unsettled pointer arm, pointer, calibrated scale and handle sleeve pipe, the lower level of spanner head has one section handle, unsettled pointer arm upper end and handle fixed connection, at unsettled pointer arm lower extreme connection pointer, the elastic torsion pole is connected between handle and handle sleeve pipe, the calibrated scale is fixed on the handle sleeve pipe or is fixed on the pointer, observes through the atress deformation of elastic torsion pole and warp the angle. The utility model discloses the easy manufacturing, the resistant striking of convenient to use, two positive and negative directions are used, but direct observation to torque values all, nature directly perceived is strong. Can reduce intensity of labour, improve the efficiency of construction, reduce construction cost.
