[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention. Example

[0019] Please refer to Figure 1 - Figure 4 As shown, the utility model provides a bicycle with an expandable basket, including a basket body 1, a socket 15 corresponding to the position of the limit rod 12 is opened on the upper surface of the basket body 1 at the right side, and another group of sockets 15 symmetrically opened on the upper surface of the insertion rod 5 above the front side of the extension frame 4, the sockets 15 are distributed at the left and right ends of the insertion rod 5, after the extension frame 4 and the insertion rod 5 are pulled out, the sockets 15 on the left side of the upper surface of the insertion rod 5 correspond to the positions of the sockets 15 on the basket body 1, and when stored, the sockets 15 on the right side of the upper surface of the insertion rod 5 correspond to the positions of the sockets 15 on the basket body 1, and a mounting frame 7 with a rectangular through groove is formed on the lower surface of the basket body 1, a connecting plate 8 is arranged inside the mounting frame 7, and a mounting hole 9 is opened on the connecting plate 8, and a gap is left between the connecting plate 8 and the basket body 1 and the extension frame 4 through the mounting frame 7, which does not affect the movement of the extension frame 4;

[0020] During installation, the mounting frame 7 is placed on the seat body at the rear of the bicycle, and the mounting frame 7 is fixed by bolts passing through the mounting holes 9;

[0021] like Figure 1 - Figure 4 As shown, the front and rear plates of the basket body 1 and both sides of the bottom plate are provided with card slots 2, and the inside of the card slots 2 is provided with through slots 3, and the two card slots 2 on each plate are connected through the through slots 3, and the card slots 2 inside the front and rear plates of the basket body 1 and the bottom plate are provided with insertion rods 5, and the card slots 2 outside the front and rear plates of the basket body 1 and the bottom plate are provided with card blocks 6, and the card block 6 is T-shaped as a whole, one end of which is provided in the external card slot 2, and the other end is in contact with the insertion rod 5, the card block 6 is connected to the outer side of the insertion rod 5, and the right end of the insertion rod 5 is connected to the extension frame 4, A positioning assembly is arranged on the upper surface of the basket body 1, and the positioning assembly includes a fixing frame 10, a pull plate 11, a limiting rod 12, a retaining ring 13, and a spring 14. A fixing frame 10 is arranged on the upper surface of the basket body 1, and a limiting rod 12 with its head downward is passed through the fixing frame 10. A retaining ring 13 is formed near the lower end of the limiting rod 12. A spring 14 is arranged above the retaining ring 13. The retaining ring 13 can prevent the spring 14 from falling off. The upper end of the spring 14 contacts the lower surface of the top plate of the fixing frame 10, and a pull plate 11 is formed on the upper end of the limiting rod 12.

[0022] When it is necessary to expand the use space of the basket, the pull plate 11 is pulled upward to withdraw the limiting rod 12 from the insertion hole 15 on the right side of the upper surface of the insertion rod 5, and the extension frame 4 is pulled to the right, and the extension frame 4 drives the insertion rod 5 and the card block 6 to slide along the card slot 2 until the insertion hole 15 above the insertion rod 5 corresponds to the position of the insertion hole 15 on the basket body 1. At this time, the limiting rod 12 is pushed by the spring 14, so that the limiting rod 12 passes through the insertion hole 15 on the basket body 1 and is inserted into the insertion hole 15 above the insertion rod 5, so as to limit the insertion rod 5 and the extension frame 4. If it is necessary to adjust the basket to a normal size, the pull plate 11 is pulled upward to drive the limiting rod 12 to move upward, and the spring 14 contracts under the action of the retaining ring 13, so that the limiting rod 12 is withdrawn from the insertion hole 15 above the insertion rod 5, and then the extension frame 4 is pushed to the left until the limiting rod 12 passes through the insertion hole 15 on the basket body 1 and is inserted into the insertion hole 15 on the right side above the insertion rod 5;
