1. An apparatus for locking one or more circuit boards in position between a pair of guide rails, the apparatus comprising:
a slider attached to a sidewall of one guide rail, wherein the slider is allowed to slide along the guide rail within a predetermined range; and
one or more plunger-and-spring assemblies, wherein a respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, wherein the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider; and
wherein sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.
