Locking concave plates 10 are fixedly installed at the ends of the two locking ropes 9. The control box 2 is a conventional device with a winding disc inside for winding the steel wire rope 8. During the hoisting process, as the base rod 1 is installed at the preset position, the steel wire rope 8 can be released through the control box 2 until the stair plate body 13 is locked and then the steel wire rope 8 is wound by the winding disc to achieve the hoisting operation;
