Shape.
Preferably, the holding hoop has 2, is respectively sleeved on 2 wheel hubs, and the holding bar is away from pull bar side
It is disposed through provided with 2 terminations in 2 through holes held tightly on hoop.
It is able to brake force being evenly distributed on each tire braked by setting 2 sets to hold hoop tightly, braking force distribution
Uniformly, it is not easy to turn on one's side.
In summary, the utility model has advantages below：
The utility model is simple in construction, optimizes the overall work mode of brake by the setting of transmission parts, improves
Braking moment, enhance braking effect.And do not allow to be also easy to produce maloperation, while brake force is evenly distributed to each braked
Tire on, braking force distribution is uniform, is not easy to turn on one's side.
