The present invention relates to an adjusting structure which is configured to be disposed between a first element and a second element. The adjusting structure includes a connecting piece which has a first fastened portion and a second fastened portion formed on the first fastened portion. Through the first fastened portion and the second fastened portion, the connecting piece is combined between the first element and the second element. As a result, when the second element is positioned on the first element inaccurately, the connecting piece enables the second element to be adjusted in position on the first element, that prevents the second element from deviation in installation.
