ABSTRACT:
A pivotal device which is fixed onto a first body and a second body and enables the first body to make rotary and upward/downward movements against the second body is provided. The pivotal device includes a rotary spindle and a holder. The rotary spindle which has a sliding track disposed on the lateral side thereof is fixed onto the first body. The holder, which is fixed onto the second holder, has a second run-through hole for pivotally connecting the rotary spindle with at least a protrusion section which is inlaid into the sliding track being disposed at the second run-through hole. When the rotary spindle rotates, the protrusion section will slide along the sliding track enabling the rotary spindle to move closer to or farther from the holder.
