The driving sleeve 1512 drives the lock tongue 152 to be pulled out of the locking notch 23 through the driving rod 1511 and the connecting block 161. The first connecting arm 12 and the second connecting arm 13 are then turned closer to the third connecting arm 14. When the limiting rod 181 is clamped at one end of the limiting opening 19 and one end of the limiting frame 182, the folding of the handle, the front wheel and the rear wheel is completed. After the linkage unlocking structure is unfolded, the handle, the front wheel and the rear wheel can be rotated and folded, so that the folding pushing toy is convenient to store.

When it is desired to deploy the pushing toy, the first connecting arm 12 and the second connecting arm 13 are turned away from the third connecting arm 14. When the limiting rod 181 is clamped at the other ends of the limiting opening 19 and the limiting frame 182, the handle, the front wheel and the rear wheel are unfolded, and the locking openings 23 on the first rotating seat 1 and the second rotating seat 2 are mutually aligned and communicated. Then, the driving sleeve 1512 is pushed to move towards the second rotating seat 2, and the driving sleeve 1512 drives the lock tongue 152 to be inserted into the locking notch 23 through the driving rod 1511 and the connecting block 161. The lock tongue 152 is engaged with the inner wall of the locking opening 23, thereby restricting the mutual rotation among the first rotation seat 1, the second rotation seat 2 and the third rotation seat 3. The drive plate 202 is then pressed, and the drive plate 202 drives the insert 203 into the socket 4, thereby facilitating a reduction in the occurrence of false pushing of the drive sleeve 1512 sliding along the second connecting arm 13.
