[0036] Then, the support rod 9 is turned outward, and the support rod 9 and the mounting block 7 are rotated so that the support rod 9 and the mounting block 7 are in the shape of Figure 1 and Figure 4In the state shown, after the adjustment is completed, the pull ring 17 is directly released. At this time, the spring 13 restores its elastic deformation, pushing the movable plate 14 and the connecting rod 12 to slide, so that the auxiliary plate 15 is inserted into the fixed groove 16 at the corresponding position, thereby facilitating the limiting of the support rod 9 and the mounting block 7. Through the arrangement of the support rod 9 and the support column 10, the ladder can be auxiliary supported. The ladder does not need to lean on external objects when in use, which enriches the use scenarios of the ladder and greatly enhances its usability. In addition, the outer surface of the ladder is coated with insulating paint, which has a certain insulation effect. Then the power maintenance personnel climb to the lower crossbar 4 or the upper crossbar 2 to repair the power equipment. In addition, after use, by reversing the above operation, the lower side bar 3 slides upward and is stored. At the same time, the support rod 9 is stored in the middle of the support column 10, and the support rod 9 is flipped inward to a position close to or parallel to the upper side bar 1, which is convenient for folding and storing the ladder, thereby improving the portability of the system.
