## Abstract

A hard disk fixing mechanism implemented in a chasses includes a fixing frame, at least one mounting frame, and at least one fixing mechanism. The fixing frame includes a base plate and a first fixing plate arranged on the base plate. The first fixing plate defines at least one through slot. The base plate bears the mounting frame. The mounting frame mounts a hard disk. The mounting frame includes a projecting portion. The projecting portion defines a through hole. The projecting portion extends from the through slot to an opposite side of the first fixing plate. The fixing mechanism includes a sliding block. The sliding block is movably arranged on the first fixing plate and extends into the through hole to lock the mounting frame.
