The invention discloses an electromagnetic type torque wrench. The electromagnetic type torque wrench comprises a handle rod and an external ring shell, wherein the handle rod and the external ring shell are of an integrated structure. The handle rod is internally provided with an iron core sleeved with a coil, a compression chamber and an air storing chamber. The handle rod is internally provided with an air inlet through-hole structure communicating with the outside world and the compression chamber and an air inlet through-hole structure communicating with the compression chamber and the air storing chamber. A single chip microcomputer (51) is installed on the side face of the handle rod, a permanent magnet is arranged at the end, located at the iron core, in the compression chamber, and a valve element plate is fixed to one end of the permanent magnet. The centers of the valve element plate and the permanent magnet are each of a through-hole structure. According to the electromagnetic type torque wrench, a twisted bolt can be effectively controlled at a largest intensity; in addition, the electromagnetic type torque wrench utilizes electromagnetism for controlling, and controllability is achieved; and according to the electric current size, the electromagnetic type torque wrench can control the twisted bolt to be effectively adjusted at a largest intensity, and the adjusting range is wide.
