     DETAILED DESCRIPTION OF THE PRESENT INVENTION  
     [0014] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
     [0015] Referring to FIGS. 1, 2, and  3 , there is shown a video photography device having moveable polarizer in accordance with the present invention. The photography device  1  comprises a seat body  10 , images signal transmission lines  20 , a flexible bellow tube  30  and a lens-photography box  40 . The top face of the seat body  10  is positioned to one end of the bellow tube  30  and the other end of the bellow tube  30  is connected to the lens-photography box  40 , and the transmission line  20  passes through the seat body  10  and the bellow tube  30  to the inner wall of the box  40 . The photography signal circuit (not shown) is corresponding to the connection point, and top face of the seat body  10  is provided with collection recess  11  of the box  40  and the bellow tube  30  such that the box  40  and the bellow tube  30  are collected to the collection recess  11 , as shown in FIG. 3, and the middle section of the side edge of the seat body  10  is provided with line collection recess  12  for collecting of transmission lines  20 .  
     [0016] As shown in FIG. 4, the seat body  10  includes a seat top housing  13 , a seat bottom housing  14  mounted to each other form top to bottom, and a circular recess  12  is formed between the two housings  13 ,  14  and the top housing  13  is provided with a through hole  15  for the passage of the transmission lines  20  to the bellow tube  30  to the inner wall of the lens-photography box  40  to connect to the corresponding connection point of the signal circuit  46 . The top face of the seat top housing  13  is connected to the image transmission line  20  at an appropriate position and is provided with initial switch  16  and a plurality of control switch  17 ,  18  to proceed with photography operation and control. Further, the housing of the photography box  40  is provided with a fixed rear cover  41  mounted with a fixing shaft  42 , and the end of the shaft  42  is a lens front cover  43 , and the bellow tube  30  at the bottom section of the fixed rear cover  41 , at the appropriate position of the lens front cover  43 , photography signal circuit  46 , a fixing block  47 , a laser module  48  and a cover plate  49  for mounting the front end of the rear cover  41  are provided, and the front cover  43  corresponding to the front end of the laser module  48 , is provided with a projection hole  43 A, and the wall at the other end of the fixed rear cover  41  connected to the lens front cover  43  is formed into ring shape, covering the focusing adjusting ring  44  of the lens  45 , and a LED module  49 A is provided between the cover plate  49  and the fixed covering plate  41 , and the cover plate  49  corresponding to the plate face of the LED module  49 A is formed into transparent or semi-transparent plate and the Laser module and LED module  49 A are directly obtained power from the lens-photography box via the transmission line  20 .  
     [0017] When in use, as shown in FIG. 5, the bellow tube  30  can be adjusted and the rear cover  43  of the lens-photography box  40  is position at a vertical such that photography shooting can be done within the scope of angle A degree and the sloping angle for shooting can be finely adjusted. When not in use, the device can be rolled and collected and the device in accordance with the present invention can be conveniently brought along.  
     [0018] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
