In order to achieve the above purpose, the technical solution of the present invention is as follows:
a linkage structure of a rear wheel is arranged on a main frame of a single-foot vehicle and comprises a mandrel, the rear wheel and a brake device, wherein the number of the rear wheels is two, the mandrel is arranged at the rear end of the main frame and is parallel to the ground, a connecting piece is sleeved on the mandrel, an axial tangent plane is formed at the end part of the mandrel, a connecting hole is formed in the center of the connecting piece, and a filling surface matched with the tangent plane is arranged in the connecting hole to enable the connecting piece to be matched with the end part of the mandrel; the connecting piece is provided with a lug, the rear wheel is provided with a groove for the lug to be inserted, the connecting piece is connected with the rear wheel through the lug inserted into the groove, the mandrel is connected with the rear wheel through the connecting piece, and the brake device is arranged on the mandrel to brake the mandrel, so that the rear wheel is braked.
Furthermore, the tail end of the mandrel is provided with a positioning screw, the end face of the mandrel is provided with a positioning screw hole, the positioning screw is matched with the positioning screw hole, the positioning screw is provided with an annular flange, and the annular flange is abutted against the rear wheel to limit the rear wheel from falling off the mandrel.
Further, the length of the lug is equal to the depth of the groove, so that the tail end of the lug abuts against the bottom of the groove, and the rear wheel is prevented from moving.
After the scheme is adopted, the mandrel has an original tangent plane, and the tangent plane is axial, and the filling surface of the connecting hole is matched with the tangent plane, so the mandrel skillfully limits the inward movement of the connecting piece by means of the intersection of the tangent plane and the tangent-free plane; secondly, being connected through the connecting piece cooperation between dabber and two rear wheels, consequently two rear wheels just can carry out coaxial transmission through the dabber, and overall structure is reliable, the dismouting of being convenient for, secondly, dabber accessible tangent plane biography power to connecting piece, and the connecting piece passes power to rear wheel through the lug again, passes power simply, and brake sensitivity is high, consequently only needs a brake equipment braking dabber just can brake two rear wheels simultaneously for the bicycle is more practical.

Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without inventive labor, please refer to fig. 1 to 5.
A linkage structure of a rear wheel is arranged on a main frame 1 of a single-foot vehicle, the linkage structure 2 comprises a mandrel 21, a rear wheel 22 and a brake device 23, please refer to fig. 3-5, the rear wheel 22 has two, the mandrel 21 is arranged at the rear end of the main frame 1 and is parallel to the ground, a connecting piece 24 is sleeved on the mandrel 21, an axial tangent plane 211 is formed at the end part of the mandrel 21, a connecting hole 241 is arranged at the center of the connecting piece 24, and a filling surface 242 matched with the tangent plane 211 is arranged on the connecting hole 241, so that the connecting piece 24 is matched with the end part of the mandrel 21; the connecting piece 24 is provided with a protruding piece 243, the rear wheel 22 is provided with a groove 221 for inserting the protruding piece 243, the connecting piece 24 is connected with the rear wheel 22 through inserting the protruding piece 243 into the groove 221, and the spindle 21 is connected with the rear wheel 22 through matching the connecting piece 24, so that the two rear wheels 22 can be coaxially driven through the spindle 21, the whole structure is reliable, and the assembly and disassembly are convenient. The mandrel 21 can transmit force to the connecting piece 24 through the tangent plane 211, the connecting piece 24 transmits force to the rear wheel 22 through the convex piece 243, the force transmission is simple, the brake device 23 is installed on the mandrel 21 to brake the mandrel 21, so that the rear wheel 22 is braked, only one brake device 23 is needed to brake the mandrel 21, the two rear wheels 22 can be braked simultaneously, the brake sensitivity is high, and the practicability of the bicycle is improved.
