The invention discloses a foldable manned bracket used for repair and maintenance of a power line. The bracket comprises support rods, wherein the adjacent support rods are connected through a support rod connecting piece group; movable hinges are arranged on connecting places of two ends of each support rod connecting piece of the support rod connecting piece group and the support rods, so that each support rod is limited and unfolded by the corresponding support rod connecting piece group to form a support frame; support rod anti-shrinkage devices are respectively arranged on two ends of each support frame; after the support rod anti-shrinkage devices are unfolded at the corresponding support frame, the support rod anti-shrinkage devices are fixedly sheathed on each support rod to prevent the support rods at the uppermost part and the lowermost part from shrinking and closing to the support rod at the middle. The bracket is simple in structure and convenient to produce, so that an operator can lie on the bracket, the distance between the operator and a lead is greatly reduced, a problem of a construction distance of the last few meters is solved, and the operator can operate electric equipment in a labor-saving manner; insulating layers coat outer surfaces of all components of the bracket, so that the bracket is safe and reliable to use.
