The back tube 4 supports the baby's back, so that the baby can sit with his back against the back tube 4.

[0025] See also Figure 2 , Figure 5 and Figure 6The front end of the safety lock assembly 7 is rotatably connected to a symmetrically arranged seat frame tube 5, and the upper ends of the two seat frame tubes 5 are respectively rotatably connected to one end of a pull rod, and the other ends of the pull rods are respectively rotatably connected to the two handlebar tubes 1, and the seat frame tube 5 is fixed by the pull rod, so that the back tube 4, the seat frame tube 5 and the bottom frame tube 6 form a placement area for the baby to sit, while ensuring the storage of the device, leaving a more comfortable placement area for the baby to sit, the two bottom frame tubes 6 are cross-intersected, and the two bottom frame tubes 6 are rotatably connected at the intersection, the two back tubes 4 are cross-intersected, and the two back tubes 4 are rotatably connected at the intersection, the handlebar tube 1, the front leg tube 2 and the rear leg tube 3 are connected through the two cross-intersecting back tubes 4 and the bottom frame tube 6, so that the connection forms a triangle, which ensures that sufficient support can be provided when the baby sits, and plays a guiding role when folding the device, so that the vehicle can be folded smaller.

[0026] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The safety lock assembly 7 includes a right folding rod 701, a left folding rod 702 and a locking rod 703. One end of the right folding rod 701 and the left folding rod 702 are respectively rotatably connected to the rear leg tube 3, and the other ends of the right folding rod 701 and the left folding rod 702 are rotatably connected. The upper end of the locking rod 703 is rotatably connected to the left folding rod 702. A limiting column 7031 is fixed on the side of the locking rod 703 opposite to the left folding rod 702. A through hole is opened on the left folding rod 702. The limiting column 7031 passes through the through hole. The right folding rod 701 and the left folding rod 702 A limit opening 7011 is provided at one end of the rotating connection, and a retaining edge 7012 is provided at the upper end of the right folding rod 701. When the device needs to be folded, the locking rod 703 is rotated with the foot or hand to rotate the locking rod 703, thereby driving the limit column 7031 to leave the limit opening 7011, and then releasing the limit between the right folding rod 701 and the left folding rod 702. At this time, the right folding rod 701 and the left folding rod 702 are folded, thereby driving the other rotating connection positions of the device to rotate, thereby realizing the overall folding of the device, reducing the overall area, and facilitating carrying.

[0027] When the utility model is used:

[0028] First, use your foot to kick the locking rod 703, and the locking rod 703 rotates, causing the locking rod 703 to rotate, driving the limiting column 7031 to leave the limiting opening 7011, thereby releasing the limit between the right folding rod 701 and the left folding rod 702, and then use your foot to kick the connection between the right folding rod 701 and the left folding rod 702 upward, at this time the right folding rod 701 and the left folding rod 702 are folded; then, use your foot to kick the connection between the right folding rod 701 and the left folding rod 702 upward while holding the handlebar 1 and pushing it forward; then, the handlebar 1 rotates around the rotating seat 10 2, the connection between the right folding rod 701 and the left folding rod 702 moves upward, and at the same time, the two ends of the back tube 4 and the bottom frame tube 6 are brought closer, so that the vehicle as a whole becomes narrower until the device is completely folded; finally, to open the device, lift the handlebar tube 1 upward and step on the connection between the right folding rod 701 and the left folding rod 702 until the right folding rod 701 and the left folding rod 702 are in the same straight line, kick the locking rod 703 to rotate, so that the limiting column 7031 is engaged in the limiting opening 7011 for locking and limiting, and the device is fully unfolded at this time.
