Abstract: A retaining mechanism for holding a circuit board and a related electronic device include a supporter, a first fixing component, a second fixing component and a third fixing component. The first fixing component is disposed on a supporting wall of the supporter, to buckle an edge of the circuit board and to constrain a movement of the circuit board in a first direction. The second fixing component is disposed on another supporting wall of the supporter, to contact against another edge of the circuit board and to constrain a movement of the circuit board in a second direction. The third fixing component is disposed on a base of the supporter. A holding portion and a hooking unit of the third fixing component respectively holds a bottom of the circuit board and inserts into an opening on the circuit board, to prevent the circuit board and the holding portion from separation.

Abstract: A back cover with an anti-theft function is for containing a monitor body cooperatively with a front frame and includes a reinforcement rib structure and a cover body having an anti-theft hole. The reinforcement rib structure is formed on an inner side of the cover body facing the monitor body and includes a first ring-shaped rib disposed around the anti-theft hole, a second ring-shaped rib disposed around the first ring-shaped rib, two longitudinal ribs, and four transverse ribs. The two longitudinal ribs extend respectively from a top end and a bottom end of the first ring-shaped rib to the second ring-shaped rib along a center longitudinal axis of the first ring-shaped rib. The four transverse ribs extend respectively from two sides of the first ring-shaped rib to the second ring-shaped rib along a center transverse axis of the first ring-shaped rib in a symmetrical arrangement.
