Patent ID: 8837158

Claim:
A blocking mechanism comprising: a chassis configured to secure a circuit board, the chassis comprising a locking structure and a bottom plate configured to support the circuit board; wherein the locking structure comprises a locking post on the bottom plate; a blocking member configured to abut the circuit board for preventing the circuit board from sliding towards the blocking member, the blocking member comprising a positioning structure slidably engaged with the locking structure; and a resilient member secured to the blocking member and comprising a mounting portion, the resilient member being engaged with the locking structure for preventing the blocking member from sliding relative to the locking structure; wherein the mounting portion defines a mounting hole, and the locking post is engaged in the mounting hole and abuts the mounting portion; the resilient member is resiliently deformable; when the resilient member is disengaged from the locking structure, the blocking member is slidable relative to the chassis to disengage the locking structure from the positioning structure.
