Locking device for heat dissipating device

摘要

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.
