Multi-functional telescopic maintaining platform for leaf margin

The invention relates to a multi-functional telescopic maintaining platform for a leaf margin. The multi-functional telescopic maintaining platform comprises a tower body; an upper suspension hoistingpoint is mounted at the upper part of one side surface of the tower body (according to different structures, the suspension hoisting point can be mounted in an electric generator cabin); a winding device is mounted at the ground position at the lower part of the other side surface of the tower body (a windlass is connected with the tower body by adopting a hoop way); a climbing bracket is mountedon the side surface of the tower body positioned on the same side of the suspension hoisting point, and moves along a fa ade of the tower body; three suspension points are arranged on a basic boom ofthe climbing bracket, and are correspondingly connected with the upper suspension point through steel wire ropes; and a telescopic boom moving along the direction perpendicular to the tower body is arranged in the climbing bra
