An extensive apparatus includes a shaft, a sensor, a display, a sleeve and a shell. The sensor is attached to the shaft so that the sensor detects torque exerted on the shaft. The display is electrically connected to the sensor so that the value of the torque detected by the sensor is shown on the display. The sleeve includes a tunnel through which the shaft extends. The sleeve is connected to the shaft so that they can only rotate together. The shell is rotationally provided around the sleeve. The display is connected to the shell so that the display is rotational relative to the shaft and easily observable regardless of the shaft. |
