A sliding groove 10 is provided on the support member 5, and the ends of the connecting rods 9 are clamped in the sliding groove 10 and slide along the sliding groove 10. In this embodiment, the cooperation between the connecting rod 9 and the sliding groove 10 can be achieved by using a convex block to cooperate with the sliding groove 10, so that it can be limited and can also slide.

[0022] In this embodiment, when the staff needs to lean the maintenance ladder against the utility pole to repair the wires on the utility pole, the maintenance ladder can be deformed and unfolded to press the pressing piece 8 on the utility pole, so that the pressing piece 8 drives the insertion rod 7 to slide relative to the limiting rod 6 on the maintenance ladder under the limit of the utility pole. At the same time, the insertion rod 7 slides in the pressing piece 8, and the two limiting rods 6 are pulled closer to each other by the insertion rod 7. In the process of approaching, the pressing piece 8 presses the connecting rod 9, which then slides inside the support member 5, so that the two limiting rods 6 can be clamped and fixed on the utility pole in contact with the pressing piece 8, so as to achieve the effect of clamping the maintenance ladder on the utility pole through the limiting rod 6, thereby preventing the maintenance ladder from slipping sideways on the utility pole, causing the staff on the maintenance ladder to fall from a height and get injured.
