The left-right direction shown in fig. 2, 4, and 6 is the front-rear direction of the vehicle frame 10, wherein the first side refers to the left side of the vehicle frame 10 in fig. 2, 4, and 6, and the second side refers to the right side of the vehicle frame 10 in fig. 2, 4, and 6.

The children trailer also comprises a push-pull rod 1 and a stay rod 2 which respectively extend along the up-down direction, a first rotation center line a of the lower part of the push-pull rod 1 extending along the horizontal left-right direction is rotationally connected with the frame 10, a second rotation center line b of the lower part of the stay rod 2 extending along the horizontal left-right direction is rotationally connected with the frame 10, the upper part of the stay rod 2 can be arranged with the push-pull rod 1 in a relative rotation mode and a relative sliding mode along the length extension direction of the push-pull rod 1, and the first rotation center line a and the second rotation center line b are parallel to each other and do not extend in a collinear mode.

The push-pull rod 1 has a first working state and a second working state on the frame 10, when the push-pull rod 1 is in the first working state, as shown in fig. 1 and 2, the upper portion of the push-pull rod 1 is suspended from the first side of the frame 10, and the length of the push-pull rod 1 extending out of the first side is L1; when the push-pull rod 1 is turned back and forth around the first rotation center line a and turned at a certain angle toward the other side of the frame 10, as shown in fig. 5 and 6, the upper portion of the push-pull rod 1 overhangs the second side of the frame 10, and the length of the push-pull rod 1 extending out of the second side is L2, where L1 < L2. The children's trailer also comprises a locking mechanism for locking the push-pull rod 1 relative to the frame 10 so as to lock the push-pull rod 1 in a first working state, wherein in the first working state of the push-pull rod 1, the locking mechanism is locked, so that the push-pull rod 1 is fixed relative to the frame 10, and a user can operate the upper part of the push-pull rod 1 on a first side of the frame 10 to push the children's trailer; in the second working state of the push-pull rod 1, the locking mechanism is unlocked, so that the push-pull rod 1 can rotate relative to the frame 10, and the user can operate the push-pull rod 1 at the second side of the frame 10 to tow the child trailer.

Referring to the drawings, in the present embodiment, a sliding member 3 is rotatably provided on an upper portion of the stay 2 about a third rotation center line c extending in the horizontal left-right direction, the sliding member 3 is relatively slidably provided on the push-pull rod 1 in the direction in which the length of the push-pull rod 1 extends, and a locking mechanism is provided between the push-pull rod 1 and the sliding member 3 for locking the two, thereby locking the push-pull rod 1 with respect to the vehicle frame 10.

Specifically, the push-pull rod 1 has two

side rods

1A and 1B respectively disposed on the left and right sides, and a cross rod 1C fixedly disposed between the upper portions of the

side rods

1A and 1B, the lower portions of the two

side rods

1A and 1B are respectively rotatably connected to the frame 10 about a first rotation center line a, the stay rod 2 has two side rods respectively disposed on the left and right sides, and the upper portion of each side stay rod 2 is rotatably connected to a sliding member 3, where the sliding member 3 is specifically a sliding sleeve, and the sliding member 3 is slidably fitted over the

side rod

1A or 1B on the corresponding side.

The two

side rods

1A and 1B are respectively arranged on the outer side parts of the frame 10 in the left-right direction, namely the distance between the two

side rods

1A and 1B in the left-right direction is larger than the width of the frame 10 in the left-right direction, so that the push-pull rod 1 can not interfere with a rod part of the frame 10 when being overturned back and forth around the first rotation center line a, and the switching between the first working state and the second working state is more convenient. The two

side rods

1A and 1B each have an upper rod 11 and a lower rod 12 which can be folded in the longitudinal direction, and the slider 3 is slidably disposed on the lower rod 12.

The lock mechanism is provided between the slider 3 and the lower bar 12 on each side.
