PIVOT TRANSMISSION DEVICE

摘要

A pivot transmission device is compact and can be assembled easily and conveniently, and includes a pivot, a base frame having a guide hole, an actuator disposed on the pivot and movable in response to turning of the base frame, and a transmission arm connected with the actuator and the base frame. When the actuator is turned and displaced, the transmission arm drives the guide hole of the base frame to move relative to the pivot for the base frame to depart from (or approach) the actuator, conforming to the operation mode of an electronic apparatus and lowering the obstruction of heat dissipation for the electronic apparatus.
