[0023] Example
[0024] Please see Figure 1 and Figure 2 A safety fence includes two fences 1, each of which is fixedly equipped with a first leg 2 and a second leg 3.
[0025] Please see Figure 1-3 Two fences 1 are connected by two connecting mechanisms. One of the connecting mechanisms includes two rotating rods 4, which are rotatably connected to two second legs 3 respectively. A connecting plate 5 and a connecting block 6 are fixedly installed on the two rotating rods 4 respectively. The connecting plate 5 has a slot and a fixing plate 7 is fixedly installed on the connecting plate 5. One end of the fixing plate 7 and the connecting block 6 are connected by a plug rod 8. When the two fences 1 are moved to the working area and the two second legs 3 on the two fences 1 are brought close together, the corresponding rotating rods 4 are rotated to make the connecting plate 5 rotate, so that the slot of the connecting plate 5 is engaged with the other rotating rod 4. The connecting block 6 and the fixing plate 7 are connected by the plug rod 8, thus completing the connection of the two fences 1.
[0026] Please see Figure 1 , Figure 2 and Figure 4Both fences 1 are equipped with adjustment mechanisms. One adjustment mechanism includes a mounting plate 12. First adjustment plates 9 are slidably mounted on both the first leg 2 and the second leg 3. Each of the two first adjustment plates 9 has multiple first connection holes. Each of the first leg 2 and the second leg 3 has a second connection hole. The second connection holes on the first leg 2 are connected to the corresponding first connection holes on the first adjustment plates 9 by first bolts 10. The second connection holes on the second leg 3 are connected to the corresponding first connection holes on the first adjustment plates 9 by second bolts 11. The mounting plate 12 is fixedly connected to the top of the two first adjustment plates 9, and a second adjustment plate 1 is fixedly mounted on the bottom of the mounting plate 12. 3. The second adjusting plate 13 is slidably connected to the fence 1. When the height of the two fences 1 needs to be adjusted, the first bolt 10 and the second bolt 11 are released to limit the two first adjusting plates 9, and the mounting plate 12 is pulled, so that the second adjusting plate 13 slides on the fence 1, and the two first adjusting plates 9 slide on the first support leg 2 and the second support leg 3 respectively. The second adjusting plate 13 is moved to a suitable position, and the first bolt 10 and the second bolt 11 are rotated to limit the two first adjusting plates 9, and then the second adjusting plate 13 is limited, thus realizing the connection and adjustment of the fence 1 and improving its practicality.
[0027] Please see Figure 1 and Figure 2 Two movable wheels 14 are symmetrically fixed at the bottom ends of the two first legs 2 and the two second legs 3. The arrangement of multiple movable wheels 14 facilitates the movement of the fence 1.
[0028] Please see Figure 1 and Figure 2 Each fence 1 is equipped with a posting board 15, which facilitates the posting of warning signs.
[0029] Please see Figure 1 and Figure 2 It should also be noted that each fence 1 is equipped with multiple warning strips 16, which serve to warn vehicles traveling at night.

[0031] In summary, when using this safety fence, the two fences 1 are moved to the work area by the cooperation of multiple moving wheels 14. The two second legs 3 on the two fences 1 are brought close together. By rotating the corresponding rotating rod 4, the connecting plate 5 is rotated, and the slot of the connecting plate 5 is engaged with another rotating rod 4. The connecting block 6 and the fixing plate 7 are connected by the insertion rod 8, thus completing the connection of the two fences 1. When the height of the two fences 1 needs to be adjusted, the first bolt 10 and the second bolt 11 are released to limit the two first adjusting plates 9. The mounting plate 12 is pulled by the handle 17, so that the second adjusting plate 13 slides on the fence 1. The two first adjusting plates 9 slide on the first leg 2 and the second leg 3 respectively, moving the second adjusting plate 13 to the appropriate position. The first bolt 10 and the second bolt 11 are rotated to limit the two first adjusting plates 9, and then the second adjusting plate 13 is limited. This realizes the connection and adjustment of the fences 1, improving practicality.
