Object of the present invention is achieved through the following technical solutions: for finely tuning the driven unit of optical element, comprise drive motor, bellows coupling, threaded rod and location-plate, one shaft coupling end of described bellows coupling is fixedly connected with the output shaft of described drive motor, another shaft coupling end of bellows coupling is fixedly connected with threaded rod, described location-plate is provided with the threaded hole running through location-plate, and described threaded rod is through threaded hole.In the present invention, drive motor acts on bellows coupling makes it rotate, threaded rod is driven to produce rotary motion by the power transmission effect of corrugated tube, cooperatively interacting again by threaded rod and location-plate upper screwed hole, make the termination relative positioning plate generation axial displacement of threaded rod, thus drive other structure generation change in location be connected with threaded rod termination.Meanwhile, corrugated tube in axial direction can extend with the performance guarantee shunk threaded rod also can realize double thread bar power transmission effect when there is axial displacement.
Improve Adjustment precision and cost-saving for reducing rotating speed, further, also comprise speed reduction unit, the input end of described speed reduction unit is connected to the output shaft of described drive motor, and the output terminal of described speed reduction unit is connected to a shaft coupling end of described bellows coupling.
Further, also comprise Flexible Connector, described Flexible Connector is fixedly connected on the outer face of location-plate.So, when the termination of threaded rod contacts with other structures or is flexibly connected, by the setting of Flexible Connector, the stability that can improve threaded rod termination and other form touch or be connected.
For protection driven unit, further, also comprise shell, described shell is provided with an openend, and described location-plate is fixedly connected with the openend of shell, and shell hollow is arranged, and described drive motor and bellows coupling are positioned at this hollow space.
For reaching good heat sinking function, improve serviceability, further, described shell is provided with window, and described window is positioned at the position corresponding to described bellows coupling.
For the stability improving this driven unit and other form touch or be connected, further, described threaded rod is provided with spherical termination.
Compared with existing type of drive, the present invention has following beneficial effect: in the present invention, drive motor acts on bellows coupling makes it rotate, threaded rod also produces rotary motion under the drive of corrugated tube power transmission effect, cooperatively interacting again by threaded rod and location-plate upper screwed hole, make threaded rod relative positioning plate generation axial displacement, thus drive other structures of being flexibly connected with threaded rod termination or drive other structure generation change in location be fixedly connected with this invention.There is provided motive power by drive motor, add the setting of speed reduction unit, this invention substantially increases speed and the precision of adjustment.Meanwhile, corrugated tube in axial direction can extend with the performance guarantee shunk threaded rod also can realize double thread torsion of bar power transmission effect when there is axial displacement, thus the stability of this invention is strong.
