As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Please refer to FIGS. 1 to 9 , an easily foldable baby stroller of the present invention includes a handle tube 10 , a locking rotating member 13 , a gear 14 , an elastic member 15 , a support rod 20 , a side armrest tube 30 , a rear leg tube 40 , a connection Tube 50 , front leg tube 60 , transmission piece 62 , connecting piece 63 and front wheel joint 70 .

The handle tube 10 is U-shaped as a whole. The handle tube 10 is provided with a switch 11 and two upper locking seats 12 . The two upper locking seats 12 are respectively located at the ends of the handle tube 10 . The switch 11 is located in the middle of the handle tube 10 .

The locking rotary member 13 is provided with a protrusion 130 . The elastic member 15 is any one of a spring, a shrapnel, and a disc spring. In this embodiment, the elastic member 15 adopts a spring. The end of the support rod 20 is provided with a lower locking seat 22 .

Two ends of the connecting pipe 50 are respectively provided with sliding pins 51, and the sliding pins 51 are cylindrical. The front leg tube 60 is provided with an installation groove 61, and the installation groove 61 is linear. The transmission piece 62 is provided with a chute 620 and a movable slot 621 . The chute 620 and the movable slot 621 are respectively located at opposite ends of the transmission piece 62 , and the chute 620 is linear. The connecting piece 63 is provided with an escape groove 630 . The front wheel joint 70 is provided with a locking pin 71 . The locking pin 71 has a cylindrical shape.

When assembling the easily foldable baby stroller, the locking rotating member 13 is rotatably mounted on the upper locking base 12 and the contact surface between the locking rotating member 13 and the upper locking base 12 is an inclined surface. The locking swivel 13 is connected to the switch 11 through a pull cord. One end of the elastic member 15 is in conflict with the lower locking seat 22 , and the other end is in conflict with the gear 14 , and the gear 14 is located between the lower locking seat 22 and the locking rotating member 13 .
