For the convenience of assembly, a large assembly gap 5 shown in fig. 3 exists between the first rod 1 and the second rod 2 in the prior art. However, the existence of the assembly gap 5 also allows the second rod 2 to have a larger moving space relative to the cross section of the first rod 1, so that the movement track of the second rod 2 is uncertain and the second rod is swayed or jammed when the second rod extends or retracts relative to the first rod 1. After long-term use, partial abrasion can be generated even, and abrasion debris blocks other movable parts, thereby causing influence on the normal use of the baby carrier.

This application is through increasing gap filler 4 on the second body of rod 2, and gap filler 4 has filled assembly gap 5 to a certain extent, makes the second body of rod 2 can stretch out and draw back in the first passageway 11 of the first body of rod 1 along relatively fixed orbit, has reduced the relative rocking between the first body of rod 1 and the second body of rod 2, makes the flexible operation of bassinet can keep smooth and easy degree for a long time, and the result of use is better.

After adding the gap filler 4 to the second rod 2, the second rod 2 is mainly in frictional contact with the first rod 1 through the gap filler 4. The part of the periphery of the gap filler 4, which can contact and rub with the first rod body 1, is a working surface, and one part of the periphery or the whole periphery of the gap filler 4 is in contact with the first rod body 1, so that the second rod body 2 can be guided and positioned, and the working surfaces can be distributed continuously or at intervals in the circumferential direction of the second rod body.

In order to further improve the stretching effect, in one embodiment, the gap filling member 4 is made of rubber or plastic. Rubber and plastics have certain flexibility, can keep better laminating degree between the inner wall of the first body of rod 1, have certain compensation ability to the shape error of the first body of rod 1 inner wall that production and processing caused. When the second rod 2 is extended along the length direction of the first rod 1, the gap filler 4 will not be jammed due to the slight deviation of the cross-sectional shape of the inner wall of the first rod 1 along the length direction.

The gap filler 4 may be mounted on the second rod 2 in various ways. In one embodiment, the gap filling member and the second rod body are integrated. After the second rod body is processed, in a section of the second rod body, one part of the outer periphery of the second rod body or the whole outer periphery of the second rod body protrudes outwards to be used as a gap filling piece. The gap filling piece and the second rod body are not detachable. In another embodiment, the gap filling member and the second rod body are of a split structure, the gap filling member may be made of a material different from that of the second rod body, and the gap filling member and the second rod body may be connected in a manner of clamping, welding, bonding, threaded connection, interference fit, or the like.
