Abstract: A clamp device includes a frame including a supporting portion formed on one end thereof. The supporting portion is adapted for abutting against a handle tube. A clamping unit includes two clamping elements. Each clamping element has a connecting portion on one end, a coupling portion on the other end opposite to the connecting portion, and a curved portion between the connecting portion and the coupling portion. The clamping unit is pivotally moved between an open position and a clamping position. The clamping elements are detached from each other in the open position, and the clamping elements are close to each other in the clamping position.
