The present invention relates to a safety device used in a slide device comprising a fixed slide and at least one of subslides formed as foldable to vary the length in the upper part of the fixed slide. The present invention further comprises a body which is installed on the fixed slide and in which a receiving part is formed; an elastic spring which is installed on the receiving part and causes restoring force in a direction opposite to the body; and a fixing part fixing the subslide formed in the mounting part on the fixed slide where the body is attached by being moved to a mounting part formed in the subslide by the elastic spring. Even when hydraulic and pneumatic systems do not work in an elastic process of the subslides existing in the fixed slide by a pressure piston, the fixing part receives the restoring force of the elastic spring and then is mounted on the mounting part, thereby fixing the subslide without a slip. |
