As a most convenient tool for riding instead of walk, in our life, the body shadow of a bicycle can be seen everywhere, shared bicycles are regularly arranged beside streets, and bicycles can be seen everywhere in part of college campuses. In addition, the concept of 'low carbon emission reduction and green trip' advocated by the nation is provided, and all the concepts lay a foundation for the market of bicycles. The bicycle basket is a complementary product of the bicycle, and the demand profit is also large. The bicycle basket is used as an inseparable part of the bicycle, can be used for placing articles to be carried about, and has a good market prospect. Whether sharing a bicycle or using a bicycle for private use, their baskets are of fixed capacity. When a small-volume article such as a key or a large-volume article such as a milk box is put in the container, embarrassment is caused. Small-volume articles can bump the wall at four positions due to unstable vehicle body, and large-volume articles can fall out of the basket due to small space of the basket. The bicycle basket is made of solid material which is prepared by processing, molding or cross-linking and curing polymer as basic component and additive at certain temperature and pressure, and the outer surface of the solid material is ABS which is plastic with large dosage at present. Due to the poor stability of the plastic, the bicycle basket can be deformed or directly damaged as soon as it falls onto the ground or hits a hard object like a wall. Thereby causing the basket to lose the function of placing small-volume articles and also influencing the aesthetic property of the bicycle to a great extent.

In addition, because the bicycle basket is fixed in size, the size of articles contained in the bicycle basket is limited, articles with small size can be placed in the bicycle basket in a collision mode due to surplus space, articles with large size cannot be placed successfully, and the articles can fall off due to vibration in the riding process even after being placed in the bicycle basket in a reluctant mode, so that great trouble is caused to the riding of the bicycle.
