Further, the first support bar and second support bar bottom are hinged with anti-skid base, it is ensured that anti-skid base
Ground is adjustable to abutting parallel to the ground always.
Folding ladder in use, firstly, the folding ladder, which is put into, needs place to be used, rotates two terraced bodies in one
Determine angle, pull open two terraced bodies, roll connecting rope on fixed pulley, two terraced bodies are fixed using fixed ball, are rotated further by
Flexible foot-driven lever, and flexible foot-driven lever is stretched out, it reaches flexible foot-driven lever in corresponding card slot, flexible foot-driven lever is carried out
It is fixed, it then can use folding ladder and take the article of eminence, and be put into parcel shelf.After folding ladder use, by telescopic leg
Treadle is extracted, and the position parallel with first support bar is turned to, and second support bar is slided into along the chute close to first support bar
Position, two terraced bodies are withdrawn using the elastic force of spring, are stored.
Compared with prior art, the utility model has the following beneficial effects:
1, it is provided with parcel shelf, can be placed an article in parcel shelf, the convenience used is improved；
2, the sliding setting and the setting of flexible foot-driven lever of second support bar, facilitates the storage of folding ladder；
3, the design of fixed ball, facilitates the fixation of device, improves the stability of folding ladder.
