The connecting rod 34 drives the connecting column 30 to move synchronously along the groove 31. The connecting column 30 drives the limiting block 29 to move. The moving limiting block 29 disengages from the knob 28. Then, the knob 28 is rotated clockwise. The rotation of the knob 28 drives the rotating rod 27 to rotate synchronously. The rotating rod 27 drives the second bevel gear 26 to rotate. The second bevel gear 26 engages and drives the first bevel gear 25 to rotate. The rotation of the first bevel gear 25 drives... Rotating shaft 24 rotates, driving the fifth gear 22 to rotate. The fifth gear 22 meshes with and drives the eighth rack 23 to move. The movement of the eighth rack 23 drives the fourth connecting block 17 to move synchronously. Furthermore, the fourth gear 18 meshes with the seventh rack 20 to rotate. The rotation of the fourth gear 18 further meshes with and drives the sixth rack 19 to move. The movement of the sixth rack 19 drives the third connecting block 13 to move synchronously. Furthermore, the third gear 14 meshes with the fifth rack 16 to rotate. The rotation of the third gear 14 further meshes with and drives... The fourth rack 15 moves, causing the second connecting block 9 to move synchronously. Further, the second gear 10 meshes with the third rack 12, causing it to rotate. The rotation of the second gear 10 further meshes with and causes the second rack 11 to move. The movement of the second rack 11 causes the first connecting block 6 to move synchronously, which in turn causes the car head 1 to move synchronously. This movement of the car head 1 achieves the effect of changing the length of the toy car, increasing its variety and satisfying children's needs for toy diversity and fun. After the car body length is adjusted, the handle 35 is released. Under the action of the spring 33, the connecting column 30 is pushed to move. The connecting column 30 causes the limiting block 29 to move synchronously. The limiting block 29 further meshes with the knob 28 to fix it, preventing the knob 28 from rotating and further preventing changes in the car body length, ensuring the stability of the car body structure. By setting a locking device for the knob 28, the length adjustment of the car body can be fixed, improving the stability of the toy, increasing the diversity of toy forms, meeting the needs of different scenarios, and improving the toy's playability.
