Pulling handle rod;
Front-wheel support, the end of described front-wheel support and described pulling handle rod is by the setting that rotates of first turning cylinder;
Rear wheel support, the rearward end of described rear wheel support and described front-wheel support is by the setting that rotates of second turning cylinder;
The side stand of a described side also comprises
Trace, an end of described trace and the end of described pulling handle rod be by the setting that rotates of the 3rd turning cylinder, and the other end of described trace and described rear wheel support are by the setting that rotates of the 4th turning cylinder;
First cross bar, described first cross bar and described front-wheel support are by the setting that rotates of the 5th turning cylinder;
Second cross bar, an end of described second cross bar and the end of described first cross bar be by the setting that rotates of the 6th turning cylinder, and the other end of described second cross bar and described rear wheel support are by the setting that rotates of the 7th turning cylinder.
When described go-cart vehicle frame was in open mode, described the 4th turning cylinder was positioned at the top of described second turning cylinder.
Because the utility model has adopted above technical scheme, its advantage is: when the go-cart vehicle frame takes place to fold, pulling handle rod rotates forward downwards around first turning cylinder, then driving the 3rd turning cylinder rotates, and then trace also is moved, it is folding that the motion of trace drives rotating backward of rear wheel support downwards, first cross bar rotates with respect to front-wheel support simultaneously, second cross bar also rotates with respect to rear wheel support, realizes drawing front-wheel support and rear wheel support in, behind the go-cart vehicle frame folding, pulling handle rod, front-wheel support and rear wheel support all are folded, utilize connecting rod mechanism to come folding stand, simple in structure, cost is low.
