[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model adds structures such as brackets, reinforcement bars and footrests to the ladder, and replaces one side of the ladder with a bracket, which can reduce the overall weight of the ladder while ensuring the supporting stability of the ladder, thereby effectively reducing the labor intensity of the staff.

[0012] 2. The utility model adds structures such as a deflection frame, a triangular ground plug and an angle positioning mechanism to the ladder. During use, the conical ground plug under the bracket and the triangular ground plug under the ladder can be inserted into the ground, thereby making the use of the ladder more stable.
