The toy can also be a natural object, namely, a non-artificial object such as sand, stone, mud, branches and the like, and the toy is not limited to a toy sold on the street for people to play, but can be called as a toy in all things which can be played, watched, listened and touched. The toy is suitable for children, more suitable for young people and middle-aged and elderly people. It is the instrument of opening wisdom skylight, lets people machine wisdom clever.

Currently, the drifting structure of the existing children toy car (patent number: CN 215663787U) comprises: the left side and the right side of the steering seat are both provided with front wheels; the front wheel seat is rotationally arranged between the front part of the front wheel seat and the steering seat around a first rotating axis, and the first rotating axis extends along the vertical direction; the steering limiting mechanism is arranged between the front wheel seat and the steering seat and is used for limiting the relative rotation angle between the front wheel seat and the steering seat; the front part of the rear wheel seat and the rear part of the front wheel seat are rotationally arranged around a second rotating axis, the second rotating axis is parallel to the first rotating axis, and the bottom rear part of the rear wheel seat is provided with a universal wheel; reset, reset and can set up between front wheel seat and rear wheel seat along the fore-and-aft direction with stretching out and drawing back, and be used for providing the elastic force along self length extending direction, carry out the reciprocating swing motion in the left and right direction through inertia, realize the drift effect.

However, in the implementation process of the above technical scheme, at least the following technical problems are found:

can not be freely adjusted: present children toy car drift structure when using, can only carry out single operation, if the children toy car that has the function of normally traveling, just can only carry out the translation, can't drift (when needs drift, just need reform transform the device, not only the process is strong, but also damage the toy car easily), and the toy car that can drift is in the same reason, when turning, because inertia effect, can't carry out normal steering, this use that just leads to the device brings very big influence, seriously influences the suitability of toy car, for this reason, we provide a children toy sports car drift wheel connection structure.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Not enough to prior art, the utility model provides a children's toys sports car drift wheel connection structure solves current children's toys car drift structure when using, can't freely switch over the technical problem of drift mode and normal mode of traveling as required.
