Abstract

A focusing structure for whole groups comprises a lens cone with the track, a first lens group and a second lens group. The effects of changing focus can be produced by the motor driving the lens cone rotatablly, on the guided end of the track of the lens cone is formed simultaneous inclined parallel sections that corresponded to the pillar of the first and the second lens groups for focusing. This present invention is only needed a group of driving controlling system for zooming and focusing, so it is not only low costs, but also can reduce the volume of the products. Therefore, this invention is really of high quality and can meet the needs of the market.
