Abstract
A pivot pin device provides a protection system. In operation/rotation, the pivot pin device achieves a height/position change effect. The pivot pin device includes a first component, a fixing shaft disposed on the first component and a second component assembled with the fixing shaft. The second component is formed with a slot for assembling with the fixing shaft. The fixing shaft is assembled with a rocking arm. A first head end of the rocking arm is pivotally connected with an eccentric shaft. A second head end of the rocking arm is pivotally connected with a subsidiary shaft assembled on the second component. When the slot of the second component is rotated around the fixing shaft to an opened position, the subsidiary shaft drives the rocking arm to swing with the eccentric shaft as a fulcrum, whereby a height/position change is achieved between the first and second components.
