[0031] Specifically, what is described above is a quick-release and quick-install structure of the tail structure of the brake structure, and usually the car needs to be folded in conjunction with a part of the main structure of the car to reduce its volume for better transportation or carrying. Here, the car body 100 also includes a bottom support tube 7, a front wheel 140 tube 110, a main support tube 120 and a handle 130, wherein one end of the front wheel 140 tube 110 is installed with the front wheel 140, and one end of the rear wheel tube 1 is installed with the rear wheel 150, one side of the bottom support tube 7 is fixedly connected to the front wheel 140 tube 110, and the other end is connected to the rear wheel tube 1 through a quick-release joint mechanism, the lower end of the main support tube 120 is fixedly connected to the bottom support tube 7, and the upper end extends upward to form a handle 130, specifically, the quick-release joint mechanism includes a spring piece 8, a third locking hole 105 and a fourth locking hole 106, wherein one side of the bottom support tube 7 is provided with a joint inner cavity 71, A third locking hole 105 is provided on one side of the connecting inner cavity 71, and the rear wheel tube 1 is sleeved in the movable inner cavity 71. A fourth locking hole 106 is provided at a position corresponding to the third locking hole 105 on the rear wheel tube 1. The spring piece 8 is located on the inner side of the tube cavity of the rear wheel tube 1 and the spring piece column 81 at its output end can simultaneously pass through the third locking hole 105 and the fourth locking hole 106 to lock the rear wheel tube 1 and the bottom support tube 7. The rear wheel tube 1 can be separated from the vehicle body 100 through the quick-release movable joint mechanism, and then the rear wheel tube 1 together with the rear wheel 150 and the brake line 2 are folded to one side of the body. In this way, the volume of the entire vehicle can be reduced to half of the original size. When it is needed later, it only needs to be unfolded, and the rear wheel tube 1 is inserted into the position of the movable inner cavity 71. When the spring piece column 81 of the spring piece 8 simultaneously passes through the third locking hole 105 and the fourth locking hole 106, the locking is completed. The whole process does not require any tools, so it is very convenient to use.

[0032] As a subsequent improved embodiment, refer to Figure 6 and Figure 7 The wire tail fixing member 4 is an embracing structure, which is sleeved on the rear wheel tube 1 and has a locking hole. The rear wheel tube 1 also has a locking hole, and another spring piece is provided in the tube cavity of the rear wheel tube at a position corresponding to the locking hole. The spring piece can pass through the two locking holes to fix the wire tail fixing member 4 on the rear wheel tube 1. The other structures are consistent with the aforementioned embodiments. According to the technical scheme of this embodiment, when folding daily, it is only necessary to press the two spring pieces at the same time, and then pull the rear wheel tube 1 out of the bottom support tube 7. When unfolding, it is only necessary to align the rear wheel tube with the tube cavity of the bottom support tube 7 and insert it. Then, when the two spring pieces reach the designated locking hole position, the plug-in installation is completed, which is very convenient.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
