A multi-stage fastening structure comprises an extension rod, a plurality of locking devices, and two fastening devices. A lateral retaining plate is formed at each end of the extension rod. A first flange and a second flange having different outer diameters from each other are formed on each of the locking devices. Each of the fastening devices comprises a sliding plate and a fastener. The sliding plate comprises: a locking part formed by bending the sliding plate; a trench formed on the sliding plate; a track mounted on each side of the trench; and a plurality of through holes formed on the sliding plate in front of the trench. The fastener comprises: a slideway on each side; an inward retaining plate on one edge of the fastener; a fingerboard on the other edge of the fastener; and a locking pawl formed on the bottom of the fastener near the fingerboard.

Multi-stage fastening structure

A rotary-type fastening structure for fixedly coupling an extension rod with a coupling plate, having a rotatable fastening device in the form of a main body with an off-center shaft hole. The rotatable fastening device can be rotated off-center so as to lean its lateral edge on the coupling plate and selectively secure the extension bar to the coupling plate.

Rotary-type fastening structure

A hard diskdrive rack assembly is constructed to include a rack and hard diskdrive boxes detachably installed in respective receiving chambers in the rack. The rack has a base frame, the base frame having hooks and locating holes respectively provided at upright sidewalls and partition plates thereof, and a cover covering the base frame, the cover having locating holes and hooks respectively forced into engagement with the hooks and locating holes of the base frame. Each hard diskdrive box has a pivoted pull handle turned between an open position where can move a hard diskdrive in and out of the respective hard diskdrive box, and a close position where the respective hard diskdrive box is locked in the corresponding receiving chamber in the rack.
