As shown in fig. 1 to 3, the front wheel assembly 2 includes a front wheel seat 21 fixedly connected to the frame 1, and a front wheel 22 rotatably connected to a bottom of the front wheel seat 21 through a front wheel axle 23, and specifically, the front wheel seat 21 is a universal wheel seat. The rear wheel assembly 3 includes a rear joint base 31, and a rear wheel 32 rotatably connected to the rear joint base 31 by a rear wheel axle 33. The seat pocket 4 includes a seat 42 on which a child sits, and a backrest 41 rotatably connected to a rear portion of the seat 42 by a rotation shaft n, and the seat pocket 4 is detachably provided on the frame 1.

As shown in fig. 1 to 3, the vehicle body frame 1 includes a front wheel bracket 11, a rear wheel bracket 12, a lower slider 13, a push rod frame 14, a stay 15, a driving rod 16, a support seat 17, an upper slider 18, and a link 19.

As shown in fig. 1 to 3, when the frame 1 is in the unfolded state, the front wheel bracket 11 includes a bottom bar 111 extending in the front-rear direction, and a cross bar 112 fixedly provided in front of the bottom bar 111 and extending in the left-right direction, the front wheel assemblies 2 have two sets, and the front wheel seats 21 of the two sets of front wheel assemblies 2 are fixedly mounted on the left and right ends of the cross bar 112, respectively.

As shown in fig. 1 and fig. 6, the lower sliding member 13 is slidably disposed on the bottom rod 111 along the front-back direction, and in this embodiment, the lower sliding member 13 is specifically a sliding sleeve sleeved on the bottom rod 111.

As shown in fig. 1 to 3, the rear wheel support 12 has two sets disposed on the left and right sides of the bottom bar 111, and in the unfolded state, the rear wheel support 12 extends in the front-rear direction, and the two sets of rear wheel supports 12 extend obliquely outward from the front to the rear, and the rear portion of each set of rear wheel supports 12 is provided with the rear wheel assembly 3.
