Description

Push-pull dual-purpose twin folding frame Technical Field The invention relates to a folding frame technology, in particular to a twin folding frame for pushing and pulling. Background The child cart is a toy used before the child walks, and the object to be used is a child before the child walks without autonomous ability, so that the primary attention is safety during purchasing, and besides the structure of the whole cart is firm, the primary attention is provided with a locking safety device of a locking mechanism or not; In the prior art, the child cart can only be carried by one child in the use process, has smaller applicability to twins families, is more economical, occupies larger space and is inconvenient to move when a parent is out to play, and the child cart is moved in a pushing mode when the child cart is used, so that the child cart is pushed to be pushed to move in a rugged environment, so that the user is easy to feel tired, and is difficult to drag due to limitation of the inclination angle of the cart frame when the child cart is dragged in a reverse dragging mode; the application provides a solution to the technical problem. Disclosure of Invention The invention aims to prevent the situation of large occupied space and inconvenient movement from occurring when the cart is used by placing one child in the cart and placing the other child at the pedal position of the cart, so that the economic expense of a user is saved; the user can contact the connection of snap ring between telescopic link and the bracing piece, makes the whole accessible of telescopic link and telescopic link both rotate the rotation of connecting piece and carries out inclination's regulation, and when making the user carry out children's shallow dragging through the whole of traction telescopic link and telescopic link both, inclination can be adjusted at will, solves children's shallow and only can carry single children, drags the more difficult problem, and proposes a push-and-drag dual-purpose twin folding frame.
