Abstract

The utility model relates to a folding structure for stems of a bicycle. The folding structure comprises an upper stem, a lower stem and a folder, wherein the folder comprises an upper casing and a lower casing which are connected via a pivot shaft; the upper stem is connected with the upper casing of the folder; the lower stem is connected with the lower casing of the folder; an elastic pin is arranged in the junction surface between the upper casing and the lower casing of the folder; a pin hole corresponding to the elastic pin is formed in the junction surface between the upper casing and the lower casing; when the elastic pin is inserted in the pin hole, the stems are unfolded; and when the elastic pin is separated form the pin hole, the stems are folded. Since the folder is additionally arranged in the stem structure of the bicycle, the folding effect of the bicycle is favorable for enhancement, the portability of the bicycle is enhanced, and the elastic pin and the pin hole of the folder are designed in a built-in manner, therefore, the use is convenient, the structure is artistic, and the flexural strength of the folding positions of the stems is favorable for being further enhanced by matching the dual-protection of the sliding locking block.
