The a pair of upper and lower tooth of amounting to that is installed on the mechanism shell inwall centre hole, said upper and lower top of amounting to tooth all is with joint, and all there is perforate the center, and all there is the screens mouth bottom;

Two big or small identical gears that are installed on the mechanism shell inwall knock hole, there is perforate at the center of said two gears, the mutual interlock of its profile of tooth, and amount to the interlock of tooth profile of tooth with adjacent respectively;

The upper and lower tooth of amounting to rotates the tip, and

Two gears rotate the tip.

The mechanism of returning the vehicle to the garage and knock off of aforesaid a kind of baby stroller is characterized in that: there is the upper and lower tooth rotation slot of amounting to of twice at said mechanism shell edge, and a centre hole, two knock holees and a sliding tray are arranged on its inwall.

The mechanism of returning the vehicle to the garage and knock off of aforesaid a kind of baby stroller is characterized in that: said two roads lock comprises that also one is fixed on two roads lock shell and on the mechanism shell and vertically is placed on the spring between the groove of spring fixed groove and lock button bottom surface, two roads on the mechanism shell handle.

The mechanism of returning the vehicle to the garage and knock off of aforesaid a kind of baby stroller; It is characterized in that: the said mechanism upper end of returning the vehicle to the garage and knock off is connected fixingly with the handle of baby stroller respectively through the upper and lower toe joint head of amounting to a front foot pipe, the lower end is connected with baby stroller one back leg pipe through mechanism shell to be fixed

The beneficial effect of the utility model is:

At first, the utility model has adopted the twice kep to insure, and only handle is upspring pressing two road lock-switch buttons, just can carry out the operation of returning the vehicle to the garage and knock off in second step, thus the safety that has improved perambulator;

Secondly, the utility model is installed in perambulator one side, only needs when returning the vehicle to the garage and knock off singlehandedly do two simple actions in a side of perambulator: one by two roads lock button, and handle can be upspring automatically, hank handle upwards again, and perambulator moment is simple and convenient with regard to collapsible gathering;

Its three, the utility model upper end through upper and lowerly amount to the toe joint head, the lower end can join with other part of car body through mechanism shell, becomes an organic connector of perambulator, makes the perambulator integral structure more succinct.
