Abstract
A locking device (30) for mounting a heat sink (40) to a CPU (70), includes a supporting member (32), a pair of locking members (33) pivotably attached to the supporting member and each having a connecting portion (332) and a hook (333), a pressing member (34) resting on the connecting portions, a spring installed between the supporting member and the connecting portions, and an operating member (31) pivotably attached to the supporting member. The operating member is pivotable between a first position at which the operating member abuts against the pressing member and the locking members are located at a released position and a second position at which the abutting portion releases the pressing member to allow the elastic member to drive the locking members to interlock with a retention module around the CPU.
