Abstract: A buffering mechanism for a gas circuit breaker includes a center piece which includes two protrusions extending from two ends thereof and two match surfaces are defined in two opposite sides of the center piece. Two side boards each have a pivot hole and a slot defined therethrough, the two protrusions of each end of the center piece are pivotably engaged with the pivot hole and the slot respectively. A plurality of impact plates are engaged with the two match surfaces of the center piece. When the impact plates are hit by the two links of the Y-shaped link mechanism of the gas circuit breaker at different times, the center piece is pivoted along the slots to absorb impact forces from the two links.

Abstract: A water bottle carrier for bicycles is fixed onto a frame of a bicycle by an axial base, and the axial base axially contains a handle of the water bottle. A transversal second connecting section is disposed at the bottom of the handle, and a first, a second and a third hole passages are interconnected to the axial wall of the axial base. The handle is turned clockwise to drive the second connecting section to turn from the first hole passage into the third hole passage through the second hole passage and fix the water bottle into the axial base. On the other hand, the handle is turned counterclockwise to turn the second connecting section form the third hole passage to the first hole passage to take out the water bottle.
