The working platform and the opposite platform contact to each other via at least two bumps reversely protruded between the working platform and the opposite platform. The driving unit is coupled to the working platform or the opposite platform to drive the working platform or the opposite platform to move in a horizontal direction, and the working platform generates a vibration in a vertical direction.
