The upper and lower case grooves are formed at the center of the upper and lower side faces, respectively. The upper and lower case grooves are recessed inwardly in the longitudinal direction. A wire in-place operation box is formed on the right side of the front end of the wire, which has a winding roll which coaxially and wound around the wire is unwound through a wire entry hole and rewound by a spiral spring to reposition the wire. And a plurality of insertion holes are formed in the sliding guide groove grooves at predetermined intervals in the sliding guide groove grooves. The slide fastener according to any one of the preceding claims, wherein the slide fastener comprises a sliding protrusion formed on a rear surface of the sliding plate, A plurality of fastening pins each having a fastening bar to be inserted and fixed are formed so as to protrude outward and are folded and folded in multiple stages, and a hooking bar having a fastening bar to which a hook of a hooking force is fastened and fixed is formed on the center side. And the upper and lower side guide protrusions are respectively inserted into the upper and lower case grooves and are slidably guided, respectively. On the left and right sides of the front side, the left and right pins And a storage case for storing the multi-discontinuity movement fixture formed with balls. The present invention is applied to a floor or a bottom wall of a building to prevent a serious space erosion and aesthetics from occurring, thereby avoiding the influence of the interior finishing material on the upper surface of a veranda of a multi- Can be installed, anyone can easily and comfortably ride the rope or cable hanging on the stiffener to evacuate the person to the ground. It can be moved to the left and right as needed during use. When not in use, it can be folded on the wall and kept in close contact. The structure is simple and the strength is high, so that the cost is reduced, and the structure is robust, so there is no fear of breakage or fixing, and maintenance cost is greatly reduced.
