When an adult needs to control the child car, the driving piece 55 drives the bayonet lock 51 to be separated from the low-position hole 53 and the first clamping hole 54, the handle bar 32 can be lifted upwards to reach a high-position gear, the bayonet lock 51 is clamped with the high-position hole 52 at the high-position gear, in the process, the clutch mechanism 4 is changed from a clamping state to a disengaging state, and the adult can conveniently control the direction of the child car without being interfered by the child holding the handle bar 32. When a child needs to control the child car by himself, the handle bar 32 is adjusted from the high gear to the low gear, when the handle bar 32 is in the low gear, the bayonet 51 is clamped with the low hole 53 and the first clamping hole 54, the clutch mechanism 4 is in a clamping state, and the child can drive the connecting cylinder 22 to rotate by rotating the handle bar 32, so that the wheel 23 is driven to turn.

As shown in fig. 5, the driving member 55 includes a cable 551 having one end connected to the upper portion of the handle bar 32 and the other end connected to the latch 51, the handle bar 32 is provided with an operating button 552 exposed and capable of moving in a lateral direction, the operating button 552 is provided with a pushing portion 553 capable of pushing the cable 551 to move the latch 51 by pulling the cable 551 when moving in the lateral direction, and a return spring 554 capable of returning the latch 51 is further provided between the handle bar 32 and the latch 51. When the operating button 552 is pressed, the pushing portion 553 of the operating button 552 pushes the cable 551, so that the cable 551 moves to pull the latch 51 to move laterally. Therefore, the movement of the detent 51 can be realized by pressing the operation knob 551, and the operation is very convenient.

As shown in fig. 3, the connecting tube 22 is provided with a first limiting hole 56, which can be penetrated by the latch 51 when the latch 51 is engaged with the high hole 52 and can be matched with the latch 51 to limit the rotation angle of the handle assembly 3. The arrangement of the first limiting hole 56 can limit the rotation angle range of the handle assembly 3, and ensure that the child can operate and turn more safely.

As shown in fig. 3 and 4, at least one middle hole 57 capable of engaging with the bayonet 51 is further provided between the high hole 52 and the low hole 53, a second engaging hole 58 capable of engaging with the bayonet 51 when the bayonet 51 is engaged with the middle hole 57 is provided on the connecting cylinder 22, and the clutch mechanism 4 is in an engaging state when the bayonet 51 is engaged with the middle hole 57. Therefore, the height of the handle bar 32 can be adjusted, which is convenient for children with different heights to operate and has wider applicability.

As shown in fig. 3, the clutch mechanism 4 includes a fixed shaft 41 transversely disposed to penetrate the connecting cylinder 22, an open groove 42 is formed at a lower end of the handle bar 32 to be engaged with or disengaged from the fixed shaft 41 when the handle bar 32 is lifted, the open groove 42 is disengaged from the fixed shaft 41 when the handle bar 32 is stopped at a high gear, and the open groove 42 is engaged with the fixed shaft 41 when the handle bar 32 is stopped at a low gear. When the open slot 42 is engaged with the fixed shaft 41, the clutch mechanism 4 is in an engaged state, at this time, the handle bar 32 rotates to drive the connecting cylinder 22 to rotate through the fixed shaft 41, and further control the steering of the baby carriage, when the handle bar 32 moves upwards to disengage the open slot 42 from the fixed shaft 41, the clutch mechanism 4 is in a disengaged state, at this time, the handle bar 32 rotates to not drive the connecting cylinder 22 to rotate, at this time, the handle bar 32 and the connecting sleeve 31 can rotate together relative to the connecting cylinder 22, and interference cannot be brought to the rotation of the adult operation connecting cylinder 22.

As shown in fig. 3, the connecting sleeve 31 is provided with a second limiting hole 59 through which the fixing shaft 41 transversely passes and which can limit the rotation angle of the handle assembly 3. The second position-limiting hole 59 and the first position-limiting hole 56 together limit the range of the rotation angle of the handle bar 32, ensuring the safety of the child operation.
