[0025] In this embodiment, the six-part frame 1 includes a base assembly 11, a secondary core component 12, a main core component 13, an unlocking handle 14, a linkage rod 16, a backrest assembly 17, an armrest 18, a return spring 19, and two spiral springs 15. The linkage rod 16 passes through the two spiral springs 15, and one end of it engages with the secondary core component 12, while the other end is fixed to the shaft of the main core component 13. The unlocking handle 14 is fixed to the other end of the shaft of the main core component 13. One end of the return spring 19 is connected to the unlocking handle 14, and the other end of the return spring 19 is connected to the base assembly 11. The armrest 18 is mounted on the backrest assembly 17.

[0026] In this embodiment, the reset spring 19 helps the unlocking handle 14 to reset, and the pull strap (figure omitted) is inserted into the pull strap ring 114. One end of the pull strap is fixedly connected to the unlocking handle 14.

[0027] In this embodiment, the base assembly 11 includes a template 111, a child seat fixing ring 112, a reinforcing plate 113, a pull strap ring 114, a fixing hole 115, and a lower spiral spring bracket 116. The two ends of the template 111 are respectively connected to the fixing plates 110 on both sides. The reinforcing plate 113 is fixed on the fixing plate 110 on one side, and the child seat fixing ring 112 is installed on the template 111.
