[0024] EMBODIMENT

[0025] Please refer to Figures 1-5 , a whole foldable child trailer, comprising:

[0026] The bottom plate one 1 is rotatably connected with two bottom plate twos 2, and a plurality of self-locking rollers 3 are installed on the bottom plate one 1 and the two bottom plate twos 2. A limiting mechanism is arranged between the bottom plate one 1 and the two bottom plate twos 2, the limiting mechanism comprises four grooves and four sliding grooves, the four grooves are formed on the bottom plate one 1, the four sliding grooves are respectively formed on the two bottom plate twos 2, a sliding block 17 is slidably connected in the sliding groove, one end of the sliding block 17 is located in the groove, a spring is arranged between the sliding block 17 and the sliding groove, the control block 18 is fixedly connected on the sliding block 17, the control block 18 penetrates out of the sliding groove through the control port, the spring is used to provide elastic force to push against the sliding block 17, and the sliding block 17 is used to be clamped between the bottom plate one 1 and the bottom plate two 2, so as to avoid the bottom plate one 1 and the bottom plate two 2 from being rotatably combined together.

[0027] The adjusting mechanism comprises a cloth box 4 fixedly connected to the bottom plate one 1 and the bottom plate two 2, and four fixed grooves 5 fixedly connected to the two bottom plate two 2, a support cylinder 6 rotatably connected to the fixed groove 5, a limiting tube 7 slidably sleeved on the support cylinder 6 and the fixed groove 5, a connecting plate 8 fixedly connected between the support cylinder 6 and the cloth box 4, two groups of four support cylinders 6, a support frame 9 slidably connected to the two support cylinders 6, a plurality of limiting grooves formed in the support frame 9, a screw rod 10 threadedly connected to the support cylinder 6 and located in one of the limiting grooves, four clamping grooves one 11 fixedly connected to the support frame 9 through four fixed belts, a plurality of buttons 12 fixedly connected in the cloth box 4, two shielding cloths one 13 and two shielding cloths two 14 fixedly connected to the cloth box 4, a plurality of rope rings 15 fixedly connected to the shielding cloths one 13 and the shielding cloths two 14 and matched with the buttons 12, two buckles one 16 fixedly connected to the shielding cloths one 13 and the shielding cloths two 14 and clamped with the clamping grooves one 11, the support cylinder 6, the support frame 9 and the like for height adjustment, the screw rod 10 for limiting, the rope ring 15 for limiting on the button 12, and the shielding cloths one 13 and the shielding cloths two 14 for shielding, which facilitates people to adjust the shielding height according to the situation.

[0028] Two clamping grooves two 19 and two connecting belts 20 are fixedly connected to the two bottom plate two 2, a buckle two is fixedly connected to the connecting belt 20 and clamped with the clamping groove two 19, and the overall device is fixed and limited after being folded.
