[0033] Reference Figures 3 to 5 When the limiting pin 8 is inserted into the limiting port 71, the rotating block 7 cannot rotate. Similarly, when the limiting pin 8 is disengaged from the limiting port 71, the rotating block 7 can rotate relative to the support base 1. The second spring 12 provides a buffering force for the rotating block 7 during rotation. In this embodiment, two of the second spring 12 and two of the spring sleeve 13 are provided.

[0034] Reference Figures 1 to 6The design principle of this utility model seat frame is as follows: The rotating seat 2 and the support frame 3 can be adjusted in angle to meet the different lying positions of the baby. When the support frame 3 needs to be adjusted, press the button 5 forward to disengage the position pin 51 from the original position slot 4. At this time, the rotating seat 2 and the support frame 3 can be rotated around the support base 1. When the support frame 3 is adjusted to the required angle, release the button 5 and let the position pin 51 re-insert into another position slot 4 to fix the rotating seat 2 and the support frame 3 relative to the support base 1. It should be noted that when the rotating seat 2 and the support frame 3 need to rotate, the limiting pin 8 is inserted into the limiting port 71. In addition, when the support frame 3 does not need to swing left and right, it can be manually swung up and down. When the support frame 3 needs to swing up and down, the limiting pin 8 is disengaged from the limiting port 71. At this time, the rotating block 7 is no longer fixed. When an external force is applied to the support frame 3, the rotating seat 2, the rotating block 7 and the support frame 3 can swing up and down around the support seat 1 at the same time, thereby realizing the up and down swing of the baby on the support frame 3.
