Kite wheel with brake adjusting function

The utility model discloses a kite wheel with a brake adjusting function, which comprises a foldable bracket, an anti-inversion device, a main shaft, a wire coil and a brake device, the bracket and the anti-inversion device are sequentially arranged on the main shaft, so that the kite wheel is simpler in structure. The brake device comprises a brake driving assembly, a brake tightness adjusting assembly and a friction assembly, the brake tightness adjusting assembly is provided with a threaded structure, and the overall length of the brake tightness adjusting assembly is changed, so that the pressure of the brake driving assembly on the friction assembly is rapidly increased, and the friction force between the friction assembly and the wire coil is increased. According to the kite wheel with the brake adjusting function, all the components are connected in series through the main shaft, so that the kite wheel is simpler in structure and smaller in problem occurrence probability, the problem that brake adjustm
