Abstract

The utility model relates to a novel folder which is composed of a main vehicle frame, an auxiliary vehicle frame, a folding convex block, a notch, a folding concave block and a connecting shaft. The novel folder further comprises a bearing frame, a safety block and a connecting rod. The folding concave block is connected with a bracket into one body, the bracket is flexibly connected with the connecting rod by a pin, and the connecting rod is also flexibly connected with a handle by the pin. The novel folder is characterized in that: a convex block is also arranged on the handle and is matched with the notch on the folding convex block, and the connecting rod on the handle is connected with the bearing frame; when the folding concave block and the folding convex block are clamped, under the function of a spring, the safety block of the handle is tightly locked by a safety hook on the handle and the safety block on the bracket or the safety hook on the connecting rod; therefore, the folder is tightly clamped and cannot be separated, and the handle can be opened or the folder can be separated due to any impact or foreign matters. The novel folder is fairly simple and the utilization is fairly convenient.
