As shown in FIG. 7, the rotating holder 21 has an opening 213 in its side wall 212, and the rotating holder 21 has a resilient arm 214 extending from the side wall 212 at the opening 213. The resilient arm 214 has a protrusion 215 at its end. The protrusion 215 protrudes laterally from the side wall 212. When the locking member 40 is in the locked position P3 and engaged with one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12 to be locked, the opening 213 is aligned with the extension portion 43 and the protrusion 215 is pressed, whereby the elastic arm 214 is inclined from the opening 213 towards the extension portion 43 to block the blocking portion 44 and restrict the locking member 40 from being released from the locked position P3. For example, in the seat mode (shown in FIG. 1 ), when the vehicle seat (not shown) is bearings The vehicle seat may be fixed to the support 20. The vehicle seat presses the protrusion 215 (shown in FIG. 8) corresponding to the side wall surface A at the position where the protrusion 215 is located, and in this case, the elastic arm 214 blocks the blocking portion 44, and the seat is at the seat position P1. bearings The support 20 is locked. bearings After being pressed against the support 20, the blocking portion 44 can be prevented from disengaging from the locking position P3, so that the vehicle seat cannot be adjusted from the seat position P1 to the carrycot position P2 after being pressed against the support 20. In this way, back flipping of the vehicle seat caused by an incorrect use angle can be prevented, and as a result, the safety of the vehicle seat in use can be guaranteed, i.e. the vehicle seat can only be engaged in the seat position P1.

[0055] As shown in FIG. 3, the fixed holder 10 has a first side surface 13, and the rotating holder 21 has a second side surface 216. The first side surface 13 faces the second side surface 216 when the rotating holder 21 is rotatably arranged on the fixed holder 10. As shown in FIGS. 3 and 9, the fixed holder 10 has two convex limiting portions 14 on the first side surface 13, and the rotating holder 21 has concave groove portions 217 on the second side surface 216 that correspond to the limiting portions 14. The groove portions 217 are arc-shaped and have a predetermined arc length. The limiting portions 14 limit the rotatable angle of the rotating holder 21 by taking a predetermined arc length as the movable stroke of the groove portions 217. In this embodiment, the angle is 30 to 45 degrees, preferably 42.5 degrees, but is not limited to this angle.

[0056] In actual operation, bearings When the support 20 is in the seating position P1 on the main frame body 200 and in the seating mode (as shown in FIG. 1 ), bearings When the support body 20 is switchable to the carrycot position P2, the user can pull the operating member 60 to couple with the drive lever 50 via the pulling member 70 and drive the locking member 40 from the locked position P3 to the unlocked position P4 (as shown in Figures 10 and 11), thereby disengaging the locking member 40 from the seat mode positioning portion 11; bearings The support body 20 can be rotated to the carrycot position P2 (shown in Figure 12) and thus placed in the carrycot mode. In this case, the operating member 60 is released, and the locking member 40 is reset to the locking position P3 by the resetting elastic force of the resetting member 80, and is engaged with and locked into the carrycot mode positioning portion 12 (shown in Figure 13). bearings The support body 20 is locked in the carrycot position P2, and the protrusion 215 is pressed, causing the elastic arm 214 to tilt toward the extension portion 43, blocking the blocking portion 44 (shown in Figure 8), and preventing the locking member 40 from moving out of the locking position P3. bearingsWhen switching the support 20 from the carrycot mode to the seat mode, the difference from the above operation is that after the locking member 40 is disengaged from the seat mode positioning portion 11, bearings The only difference is that the support 20 swings from the carrycot position P2 back to the seat position P1, and the rest of the operation is the same, so it will not be described in detail here.
