[0021] It should be noted that the third gear 805 is driven to rotate by the motor, the third gear 805 drives the second gear 804 to rotate, the second gear 804 drives the rotating shaft 802 to rotate, the rotating shaft 802 drives the first gear 803 to rotate, and the first gear 803 drives the rack 806 to move, thereby moving the first mounting bracket 6 and the second mounting bracket 7 to adjust the height of the second guardrail 3.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, a plug-in slot is provided at the other end of the bottom of the second guardrail 3, and sockets 13 are provided on both sides of the plug-in slot. A fixing mechanism 4 is provided through the top of the first mounting frame 6, and the fixing mechanism 4 includes a connecting shell 401 that is fixed to the inner wall of the top of the first mounting frame 6, and the connecting shell 401 is adapted to the plug-in slot. A moving plate 402 is slidably connected to the inner wall of the connecting shell 401, and two slide grooves 403 are provided at the top of the moving plate 402. The two slide grooves 403 are in an eight-shaped shape, and a connecting block is slidably connected in the slide groove 403.

[0023] It should be noted that by pulling the mounting plate outward, the mounting plate drives the insertion rod 406 to move, so that the movable plate 402 moves, so that the connecting block moves in the direction of approaching each other in the sliding groove 403, so that the two limit blocks 404 move in the direction of approaching each other, so that they move out of the socket 13 and no longer limit the second guardrail 3. When pulling the mounting plate, the second guardrail 3 is pulled outward, and the bottom ends of the second guardrail 3 are respectively moved out of the first mounting bracket 6 and the second mounting bracket 7, and then the bottom end of the second guardrail 3 is rotated to make the second guardrail 3 move out of the first mounting bracket 6 and the second mounting bracket 7. The second guardrail 3 and the limiting plate 12 can be rotated, so that the second guardrail 3 can be rotated to one side and the guardrail can be opened, which is convenient for taking the baby out or performing other operations. When the second guardrail 3 needs to be fixed, it is only necessary to press the second guardrail 3 downward while rotating and pulling the mounting plate in the opposite direction, so that the two ends of the bottom of the second guardrail 3 are respectively inserted into the first mounting frame 6 and the second mounting frame 7, and then the mounting plate is released. The spring 405 drives the moving plate 402 to move, so that the connecting blocks move away from each other, and the limiting block 404 is inserted into the socket 13.

[0024] Working principle: When the height of the second guardrail 3 needs to be adjusted, the third gear 805 is driven to rotate by the motor, the third gear 805 drives the second gear 804 to rotate, the second gear 804 drives the rotating shaft 802 to rotate, the rotating shaft 802 drives the first gear 803 to rotate, the first gear 803 drives the rack 806 to move, thereby moving the first mounting bracket 6 and the second mounting bracket 7 to adjust the height of the second guardrail 3.
