The shaking head mechanism is operated as follows: first, place the child's test finger in the position where it will be clamped. After the fan rotates to the position where the child's test finger is clamped, use a digital display tensile gauge to pull the child's test finger out along the axis perpendicular to the clamping force to determine the result - what is measured is the pulling force rather than the clamping force.
[0044] Implementation case 2:
