Abstract
A lockable braking device comprises a controlling set having a cover fixed to a frame, a braking grip pivoted to the cover and partially protruded out of the cover, a connecting member pivoted to the cover and one end thereof being propelled by the braking grip, and a crank pivoted to the cover and being motivated by the braking grip. Whereby, the braking grip adjustably controls a braking state of a braking unit to attain a common stopping performance and a constant stopping effect. Accordingly, the structure of the braking device is simplified and the operation thereof is more easy and handy.
