In the releasing status, the fastening base 320 can be rotated to another locking position, so as to switch using modes of the stroller frame 1.

The operational principle of the seat adjusting mechanism 30 is introduced as follows. When the seat member 20 is in in the reclined mode, the seat member 20 and the frame member 10 are substantially parallel with each other, and an acute angle is included between the fastening base 320 and the engaging base 310. At this time, an end of the locking component 340 abuts against the flat portion 332 of the driving component 330, and another end of the locking component 340 passes through the corresponding locking component receiving hole 322 and inserts into the corresponding first locking hole 312. When it is desired to switch the seat member 20 from the reclined mode to the horizontal mode, the user can operate the operating portion 350 to pull the linking component 360 so as to drive the driving component 330 to move along the seat member 20 upwardly, so that the locking component 340 enters into the groove portion 333 of the driving component 330 and the another end of the locking component 340 disengages from the corresponding first locking hole 312, to be in the releasing status. At this time, the fastening base 320 can be rotated to a position that the fastening base 320 and the engaging base 310 are substantially perpendicular to each other, so as to align the locking component 340 with the corresponding second locking hole 313 and insert the locking component 340 into the corresponding second locking hole 313, which leads the seat member 20 in the horizontal mode. Similarly, the seat member 20 also can be switched from the horizontal mode to the reclined mode by operating the operating portion 350 to release the driving component 340 and switch the locking pcsitions.

Please refer to FIG. 10 and FIG. 11. FIG. 10 is a diagram of another seat adjusting mechanism in the locking status according to another embodiment of the present application.
