A retainer device for attaching a heat sink (80) to a CPU (95) includes a retention module (10), a clamp (40), and a crank (70). The retention module has a rectangular base frame (12), and four posts (14, 16, 18, 20) extending upwardly from the base frame. The clamp has two spaced hinge portions (48) pivotably received in two rearmost posts of the retention module. A hook (52) depends from a front of the clamp. The crank has an offset pressing portion (72), two pivot arms (74) extending from opposite ends of the pressing portion, and an operation rod (76) extending perpendicularly from one end of one pivot arm. The pivot arms are pivotably received in two frontmost posts of the retention module. When the operation rod is rotated down toward the heat sink and locked at one rearmost post, the pressing portion resiliently presses the hook of the clamp.
