9. the method for a Pushchair as claimed in claim 1, is characterized in that, comprises the following steps:

1), in the time of need to regulating seat, can pull the seat folding pull rod, masterpiece is used in the folding lever of seat, seat folds lever clear off the seat gear dish draw-in groove, as long as before conter clockwise or clickwise seat, backrest or seat reclining are carried on the back gently, realize the adjusting of chair angle, seat is stretched, pull the seat reclining back of the body, seat reclining is upper motion dorsad, seat reclining is carried on the back backrest draw-in groove place motion before seat, and pull a front seats and back seats slide plate, the front seats and back seats slide plate travels forward, on the front seats and back seats slide plate, be snapped in the motion of lower seat plate draw-in groove place, when sliding, lower seat plate block blocks the front seats and back seats slide plate in lower seat plate, do not allow the front seats and back seats slide plate throw off,

2), when using tilt structure erecting device, the parasols strut inserts the parasols the inside, prop up in parasols, folding lower tooth inserts respectively the head of parasols strut in folding upper tooth, realize fixing, can carry out the anglec of rotation by the needs of folding lower tooth, folding upper tooth and folding middle tooth, the connecting chair bayonet lock sticks in seat, installs fixing;

3), when carrying out the operation of front-wheel fast assembling-disassembling shock absorption device, press the front-fork seat push-piece, front component can be thrown off, when throwing off front component, the front-fork seat push-piece relies on the spring on front component to automatically reset, when again pressing the front fork seat pin, be inserted into the Nose Wheel Steering axle of curved driving hack lever, the front-fork seat push-piece coordinates again in the Nose Wheel Steering axle, guarantee that front-wheel can not drop out, and the 3rd recessed pan head tapping screw plays the effect of dropping that prevents after the front-fork seat push-piece from flicking;

4), when the needs adjustable handrail, the handle adjusting of outwarding winding folder, handrail clamping block and flexible armrest easy fit, draw-in groove is arranged on flexible armrest, in handrail clamping block projection close-fitting, pull flexible armrest, the handrail clamping block is provided with the draw-in groove place with flexible armrest and is connected, and the handrail clamping block pops up, when snapping into next draw-in groove, rely on handrail clamping block spring to move down, the handrail clamping block connects in next draw-in groove, at the precession handle adjusting, and handrail clamping block and flexible armrest close-fitting co-clip, realize the purpose of elongation handrail, same shortening handrail is also in like manner;

5), when using trailing wheel braking shock absorption device, the footbrake pedal, inclined-plane on brake pedal, the pedal lock dog moves left and right respectively, promote the capable brake rod sway of Z, the capable brake rod of Z sticks in the trailing wheel draw-in groove and goes, and reaches the purpose of braking, a plane is arranged on the brake pedal inclined-plane, prevent braking failure; Pin lifts brake pedal gently again, and the pedal lock dog is thrown off Shang De plane, inclined-plane, utilizes the elastic force of z capable brake rod stop block spring and pedal lock dog spring, promotes the capable brake rod of Z and breaks away from trailing wheel;

6), when needs fold, press the fold latch button, pull fold latch to move to the handrail direction, power is transferred to the brake stay cord, again power is applied on folder fin, make folder fin indentation folder fin fixed block the inside, the vehicle frame cliding seat slides along the vehicle frame bar, effect by lower part folded spring, folded spring is among folding upper plate and folding lower plate, the vehicle frame cliding seat is slided along the vehicle frame bar, curved driving hack lever up is with, reach folding purpose, opposite when will strut vehicle frame, pull flexible armrest, the vehicle frame cliding seat is along vehicle frame bar down sliding, curved driving hack lever struts, when the vehicle frame cliding seat sticks in folder fin, form the vehicle frame of practical state.
