Abstract: A clutch capable of cushioning forward movement and guarding backward movement comprises a first mandrel, a second mandrel, a clutch sleeve, a driving stick, a clutch ring, a cushioning springs and a safety springs. The first mandrel further comprises an engagement gear surface formed on the section close to the second mandrel for the engagement with the clutch sleeve mounted on the second mandrel. The clutch sleeve is driven by the driving stick to shift longitudinally. The clutch ring is slidably mounted on the clutch sleeve, having a cushioning mechanism with the clutch sleeve. The safety springs and the cushioning springs are included in the cushioning mechanism for slowing down the engagement between the clutch ring and the engagement gear surface on the first mandrel when the driving stick drives the clutch sleeve but they are not precisely aligned.

Abstract: A bike brake has two stages of braking, including a brake drum, a drum cap, plural brake bands and a stopping structure in the brake drum and the drum cap. The stopping structure has a separator, an interactive device, plural springs, plural stopping devices able to be pushed upward and outward by the springs. In case the stopping structure is rotated to alter its angle, the stopping devices are moved upward and outward by the springs to move the stopping devices outward push the brake bands to contact and rub against the inner wall of the brake drum to perform a first stage of baking. If the stopping structure continues to alter the angle larger and larger, the springs shrink and the stopping devices also move down to rest on the stop plates to perform a second stage of strong braking.
