A protective rail comprises a rail body (2) formed by at least three linkage rod assemblies (1) whose ends are hingedly connected to each other. The linkage rod assembly (1) comprises a first linkage rod (11) and a second linkage rod (12) whose middle parts are connected to each other. The linkage rod assembly (1) has an X-shaped structure. The rail body (2) and a protective cloth (5) connected thereto can be opened or folded up by controlling a locking apparatus (3) on the rail body (2). The rail is easy to operate and carry. |
