A swivel-hinge assembly includes a main plate, a knuckle on the main plate, a first pivot shaft rotatably engaged in the knuckle, at least one end of the first pivot shaft exposed out of the knuckle and a peg positioned on the end of the first pivot shaft exposed out of the knuckle. The peg includes a limiting portion protruding out of the first pivot shaft and abutting an edge of the knuckle, wherein when the first pivot shaft is rotated and reaches a predetermined position the limiting portion of the peg abuts the main plate thereby preventing further rotation of the first pivot shaft.
