[0038] In this embodiment, when the child crawls, the fifth rotating shaft 22 is driven to rotate. When the fifth rotating shaft 22 rotates, the one-way clutch 23 fixedly connected to the outside is driven to rotate. At this time, the one-way clutch 23 drives the threaded rod 14 fixedly connected to the outside to rotate. The one-way clutch 23 allows power to be transmitted from the fifth rotating shaft 22 to the threaded rod 14, so that the fifth rotating shaft 22 drives the threaded rod 14 to rotate in the same direction. When the threaded rod 14 tries to rotate in the opposite direction, the one-way clutch 23 will be disengaged from the threaded rod 14. At this time, the rotation of the threaded rod 14 will not be transmitted to the fifth rotating shaft 22, which is convenient for the threaded rod 14 to rotate in the opposite direction. When the threaded rod 14 rotates, the threaded sleeve 13 connected to the outside thread is driven to move downward, that is, the threaded sleeve 13 drives the threaded sleeve 13 fixedly connected to the outside to move downward.

[0039] That is, the hole 32 can be opened, which is convenient for children to observe the constantly changing color plates 11, and the child will drive the second rotating shaft 16 to rotate while crawling, and the second rotating shaft 16 will cause the first bevel gear set 18 fixedly connected to the outside to rotate, and the first bevel gear set 18 will drive the third rotating shaft 19 fixedly connected to the outside to rotate, that is, the third rotating shaft 19 will drive the disc 10 fixedly connected to the outside to rotate, so that the multiple different color plates 11 arranged outside the disc 10 can be continuously moved to the hole 32, thereby improving the interaction between the child and the crawling device, attracting the baby's attention, stimulating the child's interest and enthusiasm, and improving the crawling training effect.

[0042] The fourth rotating shaft 20 is externally rotatably connected with the fourth connecting plate 30, and the fourth connecting plate 30 and the main body 1 are fixedly connected. The fourth rotating shaft 20 is externally transmission-connected with the second belt 15, and the second belt 15 and the second rotating shaft 16 are transmission-connected. The fourth rotating shaft 20 is externally fixedly connected with the second bevel gear set 21, and the second bevel gear set 21 and the fifth rotating shaft 22 are fixedly connected. The threaded rod 14 is externally fixedly connected with the first gear 24, and the first gear 24 is externally meshedly connected with the rack 25, and the rack 25 is externally fixedly connected with the slide plate 26. A slide groove 27 is provided on the outside of the main body 1, and the slide groove 27 and the slide plate 26 are slidingly connected. The main body 1 is externally fixedly connected with the third connecting plate 29, and the third connecting plate 29 is externally fixedly connected with the spring 28, and the spring 28 and the slide plate 26 are fixedly connected.

[0043] In this embodiment, when a child crawls, the waist belt 6 is fixed to the child's waist. The child crawls and the waist belt 6 drives the traction rope 5 wound around the upper end of the first rotating shaft 2 to extend. The first rotating shaft 2 and the main body 1 are rotatably connected, that is, the traction rope 5 causes the first rotating shaft 2 to rotate. The rotation of the first rotating shaft 2 causes the first belt 12 of the external transmission connection to be transmitted.

When the threaded rod 14 rotates, it will drive the first gear 24 fixedly connected to the outside to rotate. At this time, the rotation of the first gear 24 will cause the rack 25 meshing with the outside to move to the side away from the third connecting plate 29, and the rack 25 will drive the skateboard 26 fixedly connected to the outside to slide in the slide groove 27. At this time, the skateboard 26 will drive the spring 28 fixedly connected to the outside to extend, and the third connecting plate 29 fixedly connected to the outside of the spring 28 is fixedly connected to the main body 1;

[0045] The spring 28 remains stable when it is extended and retracted. When the threaded rod 14 does not rotate, the elastic action of the spring 28 will drive the rack 25 to move in the opposite direction, that is, the first gear 24 will drive the threaded rod 14 to rotate in the opposite direction, and under the action of the one-way clutch 23, it will not affect the fifth rotating shaft 22. That is, at this time, the baffle plate 31 rises to block the hole 32, so that the child cannot see the color plate 11, which is convenient for stimulating the child's enthusiasm for crawling. The sponge baffle 8 fixedly connected to the outside of the fixed column 7 is convenient for protecting the child. The inclined climbing board 9 has a certain inclination angle, which can enhance the crawling ability of the child. The hanging frame 4 fixedly connected to the outside of the main body 1 is convenient for placing the belt 6 when the belt 6 is not needed.
