The pedal 35 will remain horizontal due to the support of the support plate 16, and its bearing capacity will be increased. As the pedal 35 opens, the adjusting arm 1 32 and the adjusting arm 2 33 will again increase the bearing capacity of the pedal 35 while serving as a protective railing to prevent the construction worker from falling. When the pedal 35 is not opened, the pedal 35 will serve as a baffle to prevent the construction worker from falling during the climbing process. Example

[0029] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the stair mechanism 2 includes a ladder 21, the ladder 21 is fixedly connected to the top surface of the base plate 11, the top surface of the ladder 21 is fixedly connected to the working platform 22, one end of the side of the working platform 22 is fixedly connected to a ladder 2 24, the bottom surface of the working platform 22 is movably connected to a diagonal brace 23, the side of the diagonal brace 23 is movably connected to a bolt 25, one end of the bolt 25 passes through the side of the diagonal brace 23 and is threadedly connected to the side of the side support frame 181, and the working platform 22 is fixedly connected to the side of the side support frame 181.

[0032] like Figure 1-5 As shown, by clamping the limit column 183 inside the limit block 185, multiple devices can be stacked together to facilitate operations at high places. Under the action of pressure, the limit column 183 at the bottom will be inserted into the ground due to the existence of the guide block 184, so that the entire device remains stable during the operation. When the connection is completed, the constructor removes the turning guard plate 13 of the baffle 14 from the bottom to enter.
