Mounting apparatus for removable module

An assembly comprising:

• a chassis comprising a sidewall defining a locking slot;
• a removable module comprising a side plate and an end plate perpendicularly connected to the side plate, the side plate defining a through slot, the end plate defining a through hole adjacent to the side plate
• a mounting apparatus for mounting the removable module in the chassis, the mounting apparatus comprising
• a locking member comprising a mounting piece mounted to an inner side of the side plate near the end plate and a resilient piece extending slantingly from one end of the mounting piece away from the side plate, the resilient piece comprising a wedge formed on one end of the resilient piece away from the mounting piece and facing the through slot;
• and
• an operation member pivotably mounted to the inner side of the side plate, the operation member comprising a pressing portion, and a handle extendable through the through hole of the end plate, wherein the handle is manipulated to pivot the operation member around an axis perpendicular to the side plate such that the pressing portion presses the resilient piece to be deformed toward the side plate along a direction perpendicular to the side plate until the wedge extends through the through slot to engage in the locking slot.
