Structure for mounting hidden lines of case of computer

The invention provides a structure for mounting hidden lines of a case of a computer. The structure comprises a fixed plate and a plurality of elastic metal sheets, wherein the fixed plate is fixed on the inner wall of the case, and comprises a main body part, a plurality of lug parts and a slot; the lug parts are rectangular and inwardly protrude toward the center of the case; the slot is formed in the connection part of the lug parts and the main body part; the slot is located at the sides of the upper and lower ends of the lug parts; a containing cavity communicated with the slot is formed between the lug parts and the inner wall of the case; each elastic metal sheet comprises an arc-shaped wire containing part and metal sheet mounting parts at two ends of the wire containing part; the metal sheet mounting parts straightly extend along the up-down direction, and are inserted in from the slot of the fixed plate and then put in the containing cavity; and a through hole for containing wires is formed at the inner circumferential side of the wire containing part. According to the structure, the arrangement of the wires in the case is regular and ordered, but not disordered and unsystematic, so that using safety of a host of the computer is ensured.
