The side surface of 25 is provided with a number of lines for ease of operation. In addition, in order to enable the 1271563 dial ring 2G to perform a larger degree of rotation, the mirror chamber 3 has a focal length adjustment range, and the 12-end of the socket 1 is appropriately cut off to provide a rotation space of the ring edge 25. And the blocking wall 121 is rotated on the other side to cooperate with the limiting protrusion 22 provided on the dial ring 2, and the rotation range of the dialing device 2 is limited to the two-column 12 Between the large circumferences. Thereby, the ring edge 25 can be toggled to rotate the mirror chamber relative to the ring seat u at a large angle, so that the focus distance adjustment of the mirror chamber 3 is larger, so that the photographic lens has a larger shooting range and better shooting. effect. In the lens structure disclosed in the above embodiment, the dialing device 2 is separately manufactured from the mirror chamber 3 and assembled in the mirror chamber 3. It should be understood that this embodiment is not a selection of the present invention. It is also an alternative embodiment to integrally manufacture the dialing device 2 with the mirror chamber 3. It can also be understood that the manner in which the internal thread of the ring seat used in the displacement guide is matched with the thread outside the mirror chamber is also not the only choice of the present invention, as long as a slip guide is provided between the shirt seat and the mirror chamber, for example The guide groove and the slider allow the mirror chamber to rotate relative to each other and produce axial displacement relative to the socket, both of which are optional embodiments of the present invention. As described above, the photographic lens having the adjusting mechanism of the present invention only needs to be provided with the mirror chamber 3 of the dialing device 2 and the elastic body #4, etc., so that the fine surface can be focused and turned to realize the functions of the distant view and the close-range shooting. The number of components is reduced and the structure is simpler, which can save the tree procurement cost and simplify the manufacturing cost of the process, and the number of the photographic elements on the side is reduced, and the structure is simplified, and the miniaturization is further improved. The sex is also more conducive to the miniaturization of mobile phones, personal digital assistants (PDAs) and digital cameras. In summary, the present invention complies with the requirements of the invention patent and makes a patent application according to law.
