[0027] A chamber 18 is provided inside the lifting plate 11. Two installation slots 24 are provided at the top of the chamber 18. Both of the two installation slots 24 penetrate through the top of the chamber 18. The two installation slots 24 are symmetrically arranged based on the midpoint of the lifting plate 11. A connecting plate 15 is fixedly installed at the bottom of the seat 25. Two clamping plates 16 are fixedly installed at the bottom of the connecting plate 15. The two clamping plates 16 correspond to the positions of the two installation slots 24 respectively, and are symmetrically arranged based on the midpoint of the connecting plate 15 at the same time. The clamping plates 16 are adapted to the installation slots 24. Through holes 17 are provided on the outer walls of one sides of the two clamping plates 16.

[0029] The working principle of the portable multifunctional baby stroller provided by the present utility model is as follows:

[0030] During the assembly process of the baby stroller, first make the four traveling wheels contact the ground. At this time, the two support rods 1 are in a horizontal state. Then, the two support rods 2 can be rotated to make the two support rods 2 present a certain inclination angle, and the two rotating arms 4 are screwed out. At the same time, the two positioning rods 10 are pulled out to extend the two extension arms 5 to the maximum distance, and the two positioning rods 10 are inserted again to fix the position of the extension arms 5. Then, the two rotating rings 6 are adjusted to make the two rotating rings 6 correspond to the positions of the two threaded barrels 7, and the two threaded pin rods 8 are rotated to make the two threaded pin rods 8 screwed with the inner walls of the two threaded barrels 7, so as to fix the entire vehicle frame.

[0031] Then the seat 25 is installed. During installation, first press the two hand buttons 23 by hand to make the two hand buttons 23 approach each other, so that the two sliding plates 20 approach each other and gradually compress the two springs, so that the two springs are gradually in a compressed energy storage state, and then align the two holding plates 16 with the two installation slots 24 and put them in. After entering the chamber 18, the two holding plates 16 will gradually enter the two guide plates 19. After being placed firmly, the two through holes 17 just correspond to the two embedded rods 21. At this time, release the two hand buttons 23. Under the resetting effect of the two springs, the two embedded rods 21 move away from each other, and finally penetrate the two through holes 17 respectively to realize the positioning of the connecting plate 15 and the seat 25.

[0032] When the height of the seat 25 needs to be adjusted, the staff can rotate the adjusting cylinder 13. When the adjusting cylinder 13 rotates, the lifting plate 11 cannot rotate along with the adjusting cylinder 13 due to the limiting effect of the slide groove and the two lugs, and can only keep moving upward under the side effect of the thread. By rotating the adjusting cylinder 13, the threaded rod 14 is extended, thereby realizing the adjustment of the height of the workpiece 25.

[0033] Compared with the related art, the portable multifunctional baby stroller provided by the utility model has the following beneficial effects:

[0034] The utility model provides a portable multifunctional baby stroller. When in use, after the two support rods 2 are rotated and tilted to a certain angle, the two extension arms 5 are used to achieve positioning, so that the frame can be quickly formed. At the same time, the two retaining plates 16 are positioned by two embedding rods 21 to fix the seat 25. The whole splicing process is fast and convenient. At the same time, the height of the seat 25 can be adjusted when necessary, thereby improving the functionality of the baby seat.
