Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1: The problem of ladder placement stability is solved by supporting the ladder through the cooperation of the first supporting leg 2 and the second supporting leg 3, which is beneficial to the protection of the construction workers. Figure 1-Figure 4 The utility model provides a technical solution: a construction ladder, comprising a pedal 1, a first support leg 2 is rotatably connected to the inner side of the left end of the pedal 1, and a second support leg 3 is rotatably connected to the inner side of the first support leg 2, and a vertical rod 4 is fixedly connected to the right end of the pedal 1;

[0031] First, manually rotate the first support leg 2 and the second support leg 3 located on the inner side of the left end of the pedal 1, so that the first support leg 2 and the second support leg 3 cooperate to form an inverted "V" shape, so that the first support leg 2 and the second support leg 3 cooperate to support, and the stability of the ladder is improved by using the principle that the triangle has stability;

[0032] At this time, the first rotating rod 6 and the second rotating rod 7 arranged on the inner sides of the first supporting leg 2 and the second supporting leg 3 will rotate, so that the first rotating rod 6 and the second rotating rod 7 will rotate to a parallel position. Since a limiting block 8 is fixedly installed on the upper right side of the second rotating rod 7, the limiting block 8 will limit the first rotating rod 6 and the second rotating rod 7, thereby improving the stability of the connection between the first supporting leg 2 and the second supporting leg 3, which is conducive to the storage, folding and use of the ladder;

[0033] Embodiment 2: In this embodiment, if Figure 1-Figure 4 As shown, based on the first embodiment, a structure for the storage box 11 to move up and down is also disclosed, and its specific contents are as follows;

[0038] Since the storage box 11 is opened at the top, items can be conveniently placed in the storage box 11. When the storage box 11 is moved to the horizontal position of the pedal 1, the construction workers can quickly and conveniently take out the items stored in the storage box 11, which is conducive to improving construction efficiency and reducing the workload of construction workers. The buffer pad 12 fixedly arranged under the storage box 11 can prevent the storage box 11 from directly contacting the ground and being damaged, which is conducive to the use of the storage box 11.

[0039] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
