In order to improve the stability of the lower support supported on the ground, auxiliary frames are oppositely arranged on two sides of the lower support, and a pull rod is connected between the auxiliary frames.

The utility model discloses in outdoor, open-air electric power construction very much, insert the lower carriage with the upper bracket activity in, take-up stay cord makes the upper bracket promote suitable height in step and makes a certain horizontal pole I on the upper bracket and the horizontal pole II that is close to the round pin axle be in same height, and the board is moved the pull rod and is made horizontal pole I and horizontal pole II locked by the pull rod and be in the same place to with the bolt with the pull rod spacing fixed, thereby fix the upper bracket on the lower carriage. And the upper bracket can synchronously slide up and down on the lower bracket by pulling the pull rope with force.

The upper and lower brackets of the utility model are made of light high-strength materials such as aluminum alloy or titanium alloy, and can also be made of plastic steel materials. The utility model provides a not only use, installation, convenient to carry, sound construction moreover, stability is high, and the practicality is strong, the outdoor electric power construction of safe in utilization uses the flexible ladder.
