[0038] Furthermore, the support frame 1 includes a first support frame 11 and a second support frame 12;

[0039] Furthermore, the connecting rod is provided with a motor 26 for driving the connecting rod 2 to swing relative to the support frame 1, and the output end 261 of the motor 26 is connected to the connecting rod 2; when used as a cradle, the swinging frequency of the connecting rod 2 can be controlled by the motor 26 to reduce the manpower required by the caregiver.

[0040] As in the above-mentioned adjustable child seat, the locking mechanism 41 includes a first stopper 411 fixed to the support frame 1, and a second stopper 412 movably provided on the connecting rod 2 and movably cooperating with the first stopper 411 to lock or unlock the connecting rod 2 from swinging relative to the support frame 1;

[0041] When the seat 3 moves to the unlocking position 5, the second limiting member 412 is disengaged from the first limiting member 411, thereby releasing the lock on the connecting rod 2 and allowing the connecting rod 2 to swing relative to the supporting frame 1;

[0042] When the seat 3 leaves the unlocking position 5 , the second limiting member 412 contacts the first limiting member 411 to lock the connecting rod 2 , so that the position of the connecting rod 2 relative to the supporting frame 1 is fixed.

[0043] More specifically, the first stopper 411 is provided with a slot 4111; the second stopper 412 is provided with an inserting portion 4121 for inserting into the slot 4111;

[0044] When the inserting portion 4121 is inserted into the slot 4111, the connecting group 2 is fixed relative to the supporting frame 1;

[0045] When the inserting portion 4121 is disengaged from the slot 4111 , the connecting group 2 rotates relative to the supporting frame 1 .

[0046] As in the adjustable child seat mentioned above, a swing limit block 25 is provided on the connecting rod 2, and a swing limit slot 4112 is provided on the first limit member 411. When the insertion portion 4121 is disengaged from the locking slot 4111, the swing limit block 25 swings in the swing limit slot 4112 along with the connecting rod 2 to limit the swing angle of the connecting rod 2.

[0047] As in the adjustable child seat mentioned above, the second limiting member 412 is also provided with a regulating protrusion 4122. When the seat 3 moves to the unlocking position 5, the regulating protrusion 4122 contacts the seat 3 and moves in the direction of movement of the seat 3 until driving the insertion portion 4121 to insert into or disengage from the locking slot 4111.

[0048] Specifically, the regulating protrusion 4122 protrudes from the connection group 2. When the seat 3 descends along the connection group 2, it contacts the regulating protrusion 4122 and drives the second limiting member 412 to move along the movement direction of the seat 3, so that the insertion portion 4121 is disengaged from the slot 4111.

[0049] As in the adjustable child seat mentioned above, the connection group 2 has an upper limit protrusion 22, and the second limit member 412 is provided with a limit groove 4124 for the limit protrusion 22 to pass through, and the limit protrusion 22 and the limit groove 4124 cooperate with each other to limit the movable distance of the second limit member 412 on the connection group 2.

[0050] As in the adjustable child seat mentioned above, an elastic return member 4125 is provided in the limiting groove 4124; one end of the elastic return member 4125 contacts the inner wall of the limiting groove 4124, and the other end contacts the limiting protrusion 22 installed in the limiting groove 4124; the elastic return member 4125 is used to keep the inner wall of the groove 4124 away from the limiting protrusion 22.

[0052] When the insertion portion 4121 contacts the slot 4111 , the memory element 21 disengages from the positioning hole 4123 ; when the insertion portion 4121 disengages from the slot 4111 , the memory element 21 extends into the positioning hole 4123 to lock the position of the second limiting element 412 relative to the first limiting element 411 .

[0053] Specifically, the memory element 21 includes a concave platform 211 to connect a column 212, and a spring 213 is arranged in the cavity of the concave platform 211, and the spring 213 is used to keep the memory element 21 extending away from the seat 3;

[0054] More specifically, the connection group 2 further includes a separation groove 4124 which is communicated with the positioning hole 4123 and is arranged along the moving direction of the seat 3;

[0055] Specifically, the memory element 21 is provided with an inclined assisting surface 2111, which is arranged opposite to the inserting portion 4121. The assisting surface 2111 is used to assist the seat to move on the connecting group 2, thereby reducing the resistance brought by the memory element 21 to the seat resetting.

[0056] like Figure 8 As shown, when the second limiting member 412 is moved until the positioning hole 4123 is coaxial with the memory member 21, the spring stretches and pushes the memory member 21 so that the memory member 21 extends out of the positioning hole 4123 to lock the position of the second limiting member 412 relative to the first limiting member 411.
