Since both ends of the fixing plate 45 are respectively connected to the side walls of the second groove 102, and the second ends of the two eighth rotating rods 411 are respectively hinged to the top of the same fixing plate 45, the connection between the seventh rotating rod 49 and the eighth rotating rod 411 moves outwards to drive the clamping plate 4 to move upwards. The clamping plate 4 moves upwards and cooperates with the top wall of the second groove 102 to clamp and fix the warning slogan board, thereby improving safety warning, further improving warning effect, and facilitating replacement of warning slogan boards for different civil construction projects. When the safety isolation fence is used, the staff rotates the driving member 21 in the reverse direction, and then rotates the first rotating rod 29 to straighten the first isolation plate 2 and make it parallel to the horizontal plate of the U-shaped bottom plate 1, and then rotates the first isolation plate 2 to store it, thereby reducing the overall occupied space and realizing the storage of the civil construction safety isolation fence; At the same time, the second isolation plate 3 moves downward and then shrinks into the first isolation plate 2, further shrinking and storing the entire safety isolation fence, preventing the occurrence of a situation where the size is large after use and it is inconvenient to carry and move, thereby improving the practicality and use effect of the isolation fence; At the same time, the clamping plate 4 moves downward to release the clamping fixation of the warning sign board; At the same time, the locking of the U-shaped bottom plate 1 as a whole and the ground by the ground-inserting bolts or the counterweight blocks is released, and at this time, the staff can recover, carry and transport the safety isolation fence.

[0021] The present invention realizes the rotation and storage of the first isolation plate by setting a first storage mechanism, thereby reducing the overall occupied space and realizing the storage of the civil construction safety isolation fence; by setting a second storage mechanism, the first isolation plate is rotated and stored while the second isolation plate moves downward and then shrinks into the first isolation plate, further shrinking and storing the entire safety isolation fence to prevent the situation where the fence becomes large in size after use and is inconvenient to recover, carry and move, thereby improving the practicality and use effect of the isolation fence; by setting a clamping mechanism, the first isolation plate is rotated and stored while the second isolation plate moves downward and then shrinks into the first isolation plate, and the clamping plate moves downward to release the clamping and fixation of the warning slogan board; the present invention has a simple and reliable structure, good civil construction safety isolation effect, is easy to control, and is suitable for promotion.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
