The first inclined plate 1 is fixedly mounted on the wall. The top of the first inclined plate 1 is evenly provided with upper connecting rods 2 along its length direction. The bottom of the second inclined plate 3 is evenly provided with lower connecting rods 4 corresponding to the upper connecting rods 2 along its length direction. The upper connecting rods 2 and the lower connecting rods 4 located at the same horizontal height are connected with tread steps 5 by hinges. The side of the second inclined plate 3 away from the first inclined plate 1 is evenly provided with mounting tubes 6 along its length direction, and vertical rods 9 are detachably connected thereto. A protective component is provided between the vertical rods 9.

[0019] Specifically, a threaded hole 7 is provided at the end of the mounting tube 6, and a notch 8 connected to the threaded hole 7 is provided at the top and bottom of the mounting tube 6. The bottom end of the vertical rod 9 passes through the notch 8 and the threaded hole 7, and the threaded hole 7 is threadedly connected to the stud 10 that presses the vertical rod 9.

[0020] In this embodiment, after the vertical rod 9 passes through the threaded hole 7 and the notch 8, the stud 10 is threadedly connected to the threaded hole 7. The stud 10 can press the vertical rod 9, making it easier to disassemble and assemble the vertical rod 9.
