Locking device for heat dissipating device

A combination comprising:

• an electronic component with at least two latching members provided thereabout;
• a heat sink placed on the electronic component;
• and
• a locking device mounting the heat sink on the electronic component, the locking device comprising:
• a supporting member supported on the heat sink;
• a pair of locking members discrete from and pivotably connected to the supporting member;
• a pressing member resting on the locking members;
• an operating member movably connected to the supporting member;
• and
• means for driving the locking members to interlock with the latching members when the operating member is moved from a first position at which the locking members are released from the latching members to a second position.

A locking device to mount a heat sink onto an electronic component having at least one latching member disposed next to the periphery of said electronic component, comprising:

• a supporting member having a locking member attached thereto, said locking member corresponding to said at least one latching member and capable of being complementarily engagable to said at least one latching member;
• an operating member being attached to said supporting member and moveable from a first position to a second position, said operating member having a first and a second driving portion, and said operating member being capable of staying in said first position to enable said first driving portion to drive said locking member of said supporting member and staying in said second position to enable said second driving portion to drive said supporting member;
• and
• enablement of said second driving portion to drive movement of said supporting member allowing engagement of said locking member and said at least one latching member, and enablement of said first driving portion to drive movement of said locking member allowing disengagement said locking member and said at least one latching member.
