Abstract: A pull/latch type fixing device for head-radiating fin body, including a heat-radiating fin body and two fastener units. Two sides of top end of the heat-radiating fin body are respectively formed with two latch grooves. Each fastener unit is inserted in the latch groove, including a locating frame, a latch frame and a pull lever. Two lateral walls downward extend from two ends of the locating frame. The latch frame is bridged between the latch groove and the locating frame. Two latch arms respectively downward extend from two ends of the latch frame. The pull lever is pivotally mounted on the latch frame and has a pair of cam plates. By means of turning the pull lever, the latch arms of the latch frame are biased inward by the lateral walls of the locating frame to tightly hook the latch seat beside the chip.
