[0032] The personnel place the ladder in the orchard, place the two ground claws 7 under the left leg 1 and the right leg 2 on the ground, and insert each bending plate into the soil. Since the bending plate is completely inserted into the soil, it will not slide during use, which improves safety. Then, the support tube 14 is rotated to a suitable angle and then stopped. The iron chain 22 is hung on the hook 21 to control the angle between the support tube 14 and the vertical support rod 3, which improves the stability of the ladder. Then, the support column 15 is moved downward to make the positioning hole 23 of the support tube 14 and the support rod 3 aligned. The positioning holes 23 on the column 15 overlap with each other, and then the pin 24 is inserted into the corresponding two positioning holes 23 to limit the support column 15, so that the adjustment of the ladder is completed, and the stability and safety of the ladder are improved. During use, the angle between the support tube 14 and the vertical support rod 3 may need to be adjusted to meet different needs, or the ladder may be folded to save storage space; when it is inconvenient for a person to step on the top footrest 6, the other foot may also step on the foot pad 18 at this time, which can improve the comfort and convenience of the person.
