ABSTRACT:
A latch structure disposed in a casing having a first opening and a second opening includes a pressing member, an elastic member, a hook member and a guiding member. The pressing member is disposed in the first opening. The elastic member has one side connected with the casing and the other side connected with the pressing member. The hook member pivoted with the pressing member has a hook portion and a protrusion. The guiding member has a multi-route circle groove, which has a first route, a second route, a third route, and a fourth route in turn. A step exists between two adjacent routes. The moved pressing member moves the protrusion along the first route, the second route, the third route and the fourth route such that the hook portion passes through the second opening to be exposed from the casing or be hidden inside the casing.
