As shown in fig. 1 to 6, a child tricycle comprises a frame 1, the frame 1 comprises a frame main body 11 and a seat 12 arranged on the frame main body 11, the front side of the frame main body 11 is connected with a steering assembly 2 of the child tricycle as described above, the frame main body 11 is connected with a connecting seat 21, the rear side of the frame main body 11 is provided with a back support assembly 6, the back support assembly 6 comprises a left back leg 61 and a right back leg 62 arranged on two sides of the frame main body 11, the lower ends of the left back leg 61 and the right back leg 62 are provided with rear wheels 63, and the frame main body 11 is also connected with a push rod assembly 7 for pushing the child tricycle. When a child sits on the tricycle, feet can be placed on the pedals 31, and the feet do not need to bend back and forth, so that the child sits comfortably. When the child wishes to ride alone, the pedal 31 and the curved shaft 32 are pushed inwardly and the latch edge 43 snaps into the first annular groove 33, whereupon the child can push the pedal 31 to drive the child's tricycle.

As shown in fig. 5 to 7, the push rod assembly 7 includes a lower push rod 71 connected to the frame body 11 and an upper push rod 72 that can extend and retract in the lower push rod 71, a push handle 73 is disposed at the upper end of the upper push rod 72, and a locking mechanism 74 for locking the relative positions of the upper push rod 72 and the lower push rod 71 is further disposed between them. When a person needs to push, the upper push rod 72 is pulled upwards, so that the person can push comfortably, and when the child wants to ride alone, the upper push rod 72 is slid downwards and retracted into the lower push rod 71, so that the height of the push rod assembly 7 is reduced, and the riding of the child is more stable and comfortable.

As shown in fig. 7, the locking mechanism 74 includes a locking hole 741 provided on the lower push rod 71, a fixed seat 742 is provided at the lower end of the upper push rod 72, a locking block 743 capable of sliding transversely in the fixed seat 742 to engage with or disengage from the locking hole 741 is provided in the fixed seat 742, a sliding block 744 capable of sliding up and down in the fixed seat 742 is provided in the fixed seat 744, a driving portion 745 capable of pushing the locking block 743 to disengage from the locking hole 741 when the sliding block 744 slides up is provided on the sliding block 744, a sliding sleeve 746 capable of sliding relative to the sliding block is provided on the outer side of the upper push rod 72, a pull rope 747 for connecting the sliding sleeve 746 and the sliding block 744 is provided in the upper push rod 72, a first elastic reset member 748 capable of pushing the sliding block 744 to slide and reset is provided between the fixed seat 742 and the sliding block 744, and a second elastic reset member 749 capable of pushing the sliding and resetting the locking block 743 is provided between the fixed seat 742 and the fixed seat 742. When the position of the upper push rod 72 needs to be adjusted, the sliding sleeve 746 is slid upwards, the sliding sleeve 746 pulls the sliding block 744 to slide through the pull rope 747 in the sliding process, the driving portion 745 on the sliding block 744 drives the locking block 743 to disengage from the locking hole 741 on the lower push rod 71, and at this time, the position of the upper push rod 72 can be adjusted, so that the operation is very convenient and quick.
