Abstract: A torque multiplier includes a main body, a torque input shaft, at least one torque sensor, an angle sensor, and an information transmission circuit. The main body contains therein at least one gear train. The gear train has upper and lower ends respectively forming a torque input port and a torque output shaft.

The torque input shaft has an end fit into the torque input port and an opposite end coupleable with a torque device, such as a hand tool, an electrical tool, or a pneumatic tool. The torque device applies a torque input to the torque input shaft that in turn rotates the gear train to provide a multiplied torque output to the torque output shaft. The torque sensor is mounted to a surface of the torque output shaft of the gear train of the main body to detect the torque value of the torque output shaft and provide a torque value signal.
