Therefore, many commuters or students gradually choose bicycles as commuter vehicles; use bicycles to go to work or go to school, in addition to being able to strengthen the body. 'It can save a lot of transportation costs for yourself. Therefore, there are many bicycles that are easy to fold on the market. After the bicycle is folded, it is not only small in size but also light in weight, so it is convenient for commuters to carry when commuting or traffic jam, but even if the bicycle is small and light, the advantages are 'But when moving, it is still a burden for women or children with less strength. Therefore, in order to reduce the negative ## when women or children carry bicycles, or to facilitate the movement of folding bicycles, There is still considerable room for improvement in the structure of a folding bicycle. [New content] The main purpose of the present invention is to provide a folding bicycle having an auxiliary wheel, which can be moved in a sliding manner after the bicycle is folded, thereby burdening the folding bicycle. The technical means of folding is to have the main frame of the auxiliary wheel 4 M353868; a wheel carrier is arranged at the front end of the main frame, the front wheel frame is pivoted - the front wheel, and the front wheel frame and the main frame are arranged a first dismounting device is provided, and the front wheel frame has a first pivoting device for folding the front wheel frame; a rear wheel frame is disposed at the rear end of the main frame, and the rear wheel frame is pivoted a rear wheel, and a second disconnecting device between the rear wheel frame and the main frame, and a second pivoting device on the rear wheel frame for folding the rear wheel frame; and an auxiliary wheel frame, The system is pivotally disposed at the rear end of the main frame, and a support wheel is pivoted thereon. With the above structure, when the front and rear wheel frames are folded toward the inner side of the main frame, the «Xi auxiliary wheel frame will also be bent downward with the folding of the rear wheel frame, so that the auxiliary wheel on the auxiliary wheel frame Landing 'moving the bicycle by means of sliding, has the advantages of labor saving and convenient movement. [Embodiment] Referring to the first figure, the present invention is a folding bicycle with an auxiliary wheel, including a main frame (1〇), a front wheel frame (20), and a rear wheel frame (30). And an auxiliary wheel carrier (40); wherein the front wheel carrier (2〇) is connected to the front end of the main frame (1〇), the front wheel carrier (2Q) is pivoted 1 wheel (21), and the wheel carrier ( 20) Connecting with the main frame (10) - the first disconnecting device (called ^: the front wheel carrier (20) has a first pivoting device (23) for the front wheel carrier (20) toward the main vehicle The frame is pivoted for folding. "The rear wheel frame is mounted on the rear end of the main frame (1"), and the rear wheel is provided with a rear wheel (31), and the rear wheel frame (3G) and the main frame (10) The connection is set to 5 M353868 - the second disconnecting device (32)' and the rear wheel carrier (3) has a second habitat (10) for the rear wheel frame (30) toward the main frame (10) side (10) Please refer to the second and third figures. The auxiliary wheel carrier (4〇) frame is placed at the rear end of the main frame (1〇) and the corresponding rear wheel frame (30); In this embodiment, the auxiliary wheel carrier (40) is JL ancient 3^, and has a rectangular frame. The frame is composed of two straight rods (41) and a plurality of cross rods (42). One end of the straight rod (41) is pivoted at the rear end of the main frame (10), and the chanting (41) is at the other end. The crossbar (42) is pivotally provided with an auxiliary wheel (43), and two yokes (42) adjacent to the main frame (10) are provided with two supporting rods (44) connected to the rear wheel carrier (3Q). For the support of the auxiliary wheel frame (40). Please refer to the fourth figure to the seventh figure. When the bicycle is folded, the rear wheel frame state can be made by the first: disconnecting device (32). The main frame (10) is separated from the rear wheel frame (30), and the rear wheel (31) is placed under the main frame (10) by a second pivoting device (33) on the rear wheel carrier (3Q). (4) During the stacking process, the rear wheel carrier (30) will also drive the auxiliary wheel carrier state to pivot downward by the support rod (44), and the auxiliary wheel (43) on the auxiliary wheel carrier (4Q) And the front wheel carrier (20) separates the main frame (1q) from the front wheel frame (20) from the first dismounting device (22) by the first dismounting device (22), and borrows The front wheel (21) is folded inwardly under the main frame by the first pivoting device (23) on the front wheel frame (4) Since the auxiliary wheel (43) on the auxiliary wheel carrier (40) is in contact with the ground, it is convenient for the carrier to shift the bicycle, thereby making it easier to move the folding bicycle. The present invention has been in the foregoing embodiment. The specific practices of this creation have been revealed, but it is not limited to the scope mentioned in the previous examples. Any modifications and changes made in the absence of 6 M353868 belong to the spirit and scope of this creation.
