Pressing piece is pressed, the first bindiny mechanism the second state is switched into by first state so that upper boom and lower beam can
Overturn, then overturn upper boom to the front portion of baby's vehicle main body so that upper boom and lower beam close up with relative；
During upper boom is overturn, the second rotation seat pulls up drag-line, when upper boom is turned to close to the position of lower beam,
Drag-line pulls out fixture block 604 out of two necks 607, so that the second bindiny mechanism switches to the second shape by first state
State so that lower beam, foreleg and back leg can relative upsets；
Continue upper boom to the anterior upset of baby's vehicle main body until upper boom and lower beam close up, then by lower beam to perambulator
The rear portion of main body is overturn so that lower beam is gradually drawn close to back leg, and when lower beam is overturn, lower beam drives handle to rotate, when handle is rotated
The synchronous axial system of the 6th rotation seat 802 is driven, by the second fluted disc 804 to close to the 7th rotation seat 803 when the 6th rotation seat 802 is rotated
Direction promote；
After lower beam flips an angle, the 3rd bindiny mechanism is switched to the second state by handle by first state so that
7th rotation seat 803 unlocks mutually locking state with fixed seat 801, then due to the active force of torsion spring 806 so that the 7th rotates
Seat 803 is overturn to the rear portion of baby's vehicle main body, so as to drive guard block 5 to be overturn to the rear portion of baby's vehicle main body；
Then lower beam and foreleg are overturn to relative direction, to cause lower beam, back leg and foreleg to close up；
Complete the folding of perambulator.
