Claim:
An assembly comprising: a) a frame having a plurality of guiding holes, each guiding hole including a horizontal guiding slit, a sideways bracing and a pair of bracing holes above and below the guiding slit; b) a side cover mountable onto the frame, the side cover including a bent edge having a C-shaped hole; c) a clamp including a clamping piece and a clamp socket, i. the clamping piece including a pair of rounded axles, disposed on upper and lower sides at a rear end thereof, a pushing piece on a front end thereof and a pressure piece on a side thereof, and ii. the clamp socket including a central slit for receiving the clamping piece, a pair of rounded axle sockets on upper and lower ends of the central slit for receiving the pair of rounded axles, upper and lower fastening hooks formed on a front side thereof for engaging the bracing holes, and a backward hook on a backside thereof for engaging the sideways bracing; and d) wherein after the clamp is mounted to the frame and the side cover is positioned onto the frame, pushing the pushing piece causes the clamping piece to pivot about axle sockets and engage within the C-shaped hole, thereby causing the pressure piece to exert pressure to the bent edge of the side cover and secure the side cover to the frame.
