Abstract
A brake comprises a bed-frame and a braking mechanism positioned on the bed-frame. The braking mechanism comprises a braking piece which includes a block part and rubbing part, and a rear wheel positioned on the bed-frame. A take-in gap is formed between the one side surface of the block part and one side surface of the rubbing part. When the braking mechanism is in braking state, the rear wheel will be taken in the take-in gap; the block part will block off the rear wheel on the onward direction of the rear wheel which presses on the rubbing part; and the rubbing part is positioned at the bottom of the braking piece thereby increasing the resistance for progression of vehicles so as to achieve the purpose of braking quickly and safely. When the braking mechanism is in release state, the rear wheel and the braking part would be apart.
