A connecting groove 401 is opened at the top of the rear end of the connecting plate 4.

[0022] As the first embodiment of this utility model: A connecting post 3 is provided at the bottom of connecting post 1 2, and a cavity is provided inside connecting post 2 3. The cavity is connected to the outside of connecting post 3 at the bottom of connecting post 1 2, and the cavity extends from the top to the bottom of connecting post 2 3. This design allows connecting post 1 2 to extend upwards from the top of connecting post 2 3. An internal thread 1 is provided on the top side of connecting post 2 3, and a threaded post is provided on one side of adjusting head 301. The outside of the threaded post engages with the internal thread 1 on the top side of connecting post 2 3. This design provides a fixing function under the action of adjusting head 301. The overall width and length of sliding groove 601 are greater than the length and width of limiting plate 501. This design allows ladder 2 6 to slide downwards on the surface of ladder 1 5 to extend the length of ladder 1 5 and ladder 2 6. The diameter of positioning hole 1 502 is the same as the diameter of positioning hole 2 602. Equally, this design allows the positioning pin 603 to be inserted into the interior of positioning hole 502 and positioning hole 602. The interior of positioning hole 602 has internal thread 2, and one end of positioning pin 603 has external thread, which meshes with the internal thread 2 inside positioning hole 602. This design provides a fixing function under the action of positioning pin 603. The bottom ends of the left and right sides of ladder 26 have internal thread 3. The side of the front end of connecting plate 4 has a limit hole, and the interior of the limit hole allows the bolt to pass through and mesh with the internal thread 3 at the bottom end of ladder 26. This design provides a fixing function for connecting plate 4 and also provides a supporting function. The width and length of the connecting groove 401 at the rear end of connecting plate 4 are greater than the width and length of the bottom of connecting column 23. This design prevents swaying when construction personnel climb ladder 5 and ladder 26.

[0023] As a second embodiment of this utility model: First, manually rotate the positioning pins 603 installed on the top of the left and right sides of ladder 26, so that the threaded end of the positioning pin 603 separates from the positioning holes 502 of the limiting plates 501 installed on the left and right sides of ladder 26. Then, manually push ladder 15 upwards. Under the action of the sliding grooves 601 on the left and right sides of ladder 15, ladder 26 can slide up and down on the surface of ladder 15. Therefore, the height of ladder 15 and ladder 26 will be extended. Then, simply align the remaining positioning holes 502 of the limiting plates 501 with the positioning pins 603, and then proceed one by one. The positioning pins 603 on both sides of the rotating ladder 26 are fixed. Then, the adjusting head 301 installed on the side of the connecting column 23 is driven to separate the threaded post at one end of the adjusting head 301 from the surface of the connecting column 3 at the bottom of the connecting column 23. At this time, the connecting column 12 can be extended upward under the action of the cavity provided inside the connecting column 23. When the connecting column 23 forms a 90-degree right angle with the ground, the adjusting head 301 can be tightened to fix it. This design is simple and easy to use, and can extend the overall height of ladder 15 and ladder 26, which is convenient for working on taller buildings.
