The utility model discloses an assistor is maintained to rural power, include to press close to the ground panel that ground set up, ground panel bottom surface front end has can be from pasting panel bottom surface swing back and forth's a preceding swing arm forward tightly through preceding hinge is articulated, and swing arm and ground panel kept stopper before the vertically before the hinged end of preceding swing arm had set firmly and has made with the ground spacing cooperation of panel front end, and ground panel top surface rear end has can be from pasting panel top surface swing back and forth's a back swing arm backward tightly through the back hinge is articulated, after the hinged end of back swing arm has set firmly and has made with the ground spacing cooperation in panel rear end the swing arm and the panel keep vertically rear stop block. It is rational in infrastructure, can make ladder lower extreme and ground fixed integrative, effectively prevent to skid, need not other people staircase, small in size, convenient to carry, the collapsible occupation space of depositing is little, also can open fast when using, and is simple to use, and helps improving work efficiency.
