Abstract:
1. A positioning device for fixing an interface card on a computer casing without using screws: a vertical wall board of a computer casing, which is provided with at least more than one long through-holes, with more than one side board surface being bended by approximate 90° along a rim of the long through-hole; at least more than one fixing seat which is fixedly connected on an interface of the vertical wall board, and is provided with a vertical shaft hole and at least more than one movable groove; more than one elastic member which is provided with a vertical shaft hole and a projected arc-shape spring leaf being emplaced into the movable groove, with a rear side of the spring leaf being formed with a poking part; a shaft, which is inserted into the shaft holes for connecting the fixing seats and the elastic members, with each of the elastic member rotating with the shaft as an axis of rotation; and an interface card, a side of which is connected with a metal cover; and an end of the cover being bended by approximate 90° with an outer board, and an inner surface of the outer board being abutted on the side board surface of the vertical wall board; the elastic member being subjected to force to rotate with the shaft as the axis of rotation, and the spring leaf being abutted on an outer surface of the outer board, such that the outer board is tightly positioned on a surface of the side board surface; on the other hand, the elastic member being subjected to force to rotate reversely with the shaft as the axis of rotation, and the spring leaf being escaped from the outer board, such that the cover and the interface card are removed from the vertical wall board simultaneously.
