Abstract
A brake mechanism including a brake block, a positioning member, a bolt and a semi-circular portion. The positioning member is mounted to the brake block and the bolt is disposed between them. Then a rod of the bolt passes through a bore which is formed on the positioning member. The semi-circular portion has a radial serration formed on one side thereon to increase the friction force between the serrated side and a brake arm which the assembly device is fastened thereon. By means of those spherical surfaces in the same curvature between the means, the brake block is always in the desired condition to achieve the purpose of stopping the rolling wheel efficiently.
