A socket ( 10 ) for electronic devices has a plurality of retainers ( 500 ). Each retainer ( 500 ) has a first member ( 501 ), a first shaft ( 507 ) for pivotably connecting a proximal portion of the first member with a lower frame ( 200 ) so the distal portion of the first member moves between an operative position in which the distal portion of the first member stays on the electronic device to make contact with an upper surface of the electronic device and an inoperative position in which the distal portion of the first member stays away from the electronic device, a second member ( 512 ) having a distal portion and a proximal portion, a second shaft ( 510 ) for pivotably connecting the distal portion of the second member with the intermediate portion of the first member; and a third shaft ( 517 ) for pivotably connecting the proximal portion of the second member with the upper frame.
