Abstract
A heat sink retention apparatus includes a frame having a first end and a second end. A rotatable shaft is mounted on the frame. A heat sink retention arm is provided on the shaft and is rotatable with the shaft between a lock position and an unlock position. A driven member is provided on the shaft. The driven member includes a slot and a plurality of grooves. A rotatable driving member is mounted on the frame adjacent the driven member. A tab on the driving member engages the slot for rotating the driven member in response to rotation of the driving member. A plurality of arcuate members on the driving member engage the grooves in response to rotation of the driving member. As a result, the retention arm is movable between the lock position and the unlock position.
