Abstract: A latch device is provided, which is used for a server. The latch device comprises: a positioning post fixed on a case of the server; a containing shelf fixed on a top cover of the server; a shifting plate fixed in the containing shelf through at least one fixing parts, wherein the fixing part permits the shifting plate moved along an opening thereof; and a rotating handle jointed with the shifting plate through two rotating axles and able to be moved between a first rotating position and a second rotating position. When the positioning post is inserted into an insertion hole of the shifting plate inside the containing shelf, the rotating handle can drive the containing shelf to be moved backward and forward, so that the top cover is driven to be moved backward and forward with the containing shelf, and the shifting plate is moved therewith.

Abstract: A latch device is provided herein, which includes a base fixedly disposed on a chassis and having an abutting side, an accommodating frame fixedly disposed on a top cover and having two bumped spring tabs on two inner sides thereof, and a rotatable handle hinged with the accommodating frame by a hinge. The rotatable handle has two openings at an end thereof near to the hinge and two holes at another end thereof far from the hinge. The rotatable handle is rotated to engage and interact the opening with the abutment side, so that the top cover engagedly covers or is separated from the chassis. The bumped spring tab is snapped into the hole after engagedly covering or before separated.
