The side of the first return spring 11 away from the lifting plate 10 is fixedly connected to the inner wall of the sliding groove. Symmetric first inserting rods 5 are fixedly arranged at the top and bottom of the side surface of the fence main body 1. The first limiting rod 9 penetrates through the sliding groove into the first inserting rod 5. A first limiting groove adapted to the first limiting rod 9 is arranged on the outer side of the first inserting rod 5. The first limiting rod 9 is slidably connected to the first inserting rod 5 through the first limiting groove. A plurality of second inserting rods 6 are fixedly arranged on the side of the fence main body 1 close to the first inserting rod 5. A slot 7 adapted to the first inserting rod 5 and the second inserting rod 6 is arranged on the side surface of the U-shaped connecting piece 2. The first inserting rod 5 and the second inserting rod 6 are respectively slidably connected to the U-shaped connecting piece 2 through the slot 7. At the same time, when the second handle 4 is pulled outwards, the first pulling plate 8, the first limiting rod 9 and the lifting plate 10 are pulled outwards, and the first return spring 11 is stretched until the first limiting rod 9 is separated from the first inserting rod 5. The adjacent fence main bodies 1 are brought close to the U-shaped connecting piece 2 and the first inserting rod 5 and the second inserting rod 6 are engaged into the slot 7. Then, when the hand is released, the first return spring 11 pulls the lifting plate 10 to move inwards.
