BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a technical filed of collecting and arranging documents. Specially, the present invention relates to an apparatus for synchronously adjusting the length needed to be cut and the external diameter of a spiral coil to drive the spiral coil into a document ring to enhance convenience of utility. 
         [0003]    2. Descriptions of the Related Art 
         [0004]    Generally, bulk papers, when collecting and arranging, are collected by paper binder, clipper, glue, blue strip, or spiral coil. But the paper binder, clipper, and glue are easy to be peeled off to miss documents. And the book tightly bound is not convenient for reading. Thus using the spiral coil for collecting the documents with holes drilled on the documents is good at difficult to be peeled, and convenient for reading. 
         [0005]    Conventionally, driving the spiral coil into the document is made by hands to drive the spiral coil ring by ring into the holes drilled on the document, and then to cut the extension ends of the spiral coil and to bend the spiral coil for preventing the spiral from departing from the document. However, the aforementioned manual operation is disadvantaged at low speed, low efficiency. After driving the spiral coil, the length needed to be cut varies with the external diameter of the spiral coil. When the length needed to be cut is too short, it cannot prevent the spiral coil from departing from the document, and when the length needed to be cut is too long, the bended portion is not convenient for later use. The manual operations cannot be done by one action and rely on experience of the operator to get better quality of work. Thus, how to drive the spiral coil with more convenient, and more efficient solution and enhance quality of work is a long-term need of users. 
         [0006]    The inventor of the present invention is experienced in RD and manufacturing of the related industry. In view of the operations relating to the spiral coil and the document, the inventor was inclined to improve it, and finally succeeded in developing An apparatus for driving a spiral coil into a document ring to enhance the convenience and efficiency of work.

         [0009]    a base; 
         [0010]    a winding bearing set, being set on the base, the winding bearing set comprising a driving shaft and an auxiliary shaft, wherein the driving shaft is driven by a driving device set on the base, and the auxiliary shaft is controlled by an adjustment module set on the base to adjust distance between the auxiliary shaft and the driving shaft to make the driving shaft and the auxiliary shaft synchronously prop up an external edge of the spiral coil;

         [0035]    Thereby, an apparatus for driving a spiral coil ( 65 ) into holes drilled on the document ( 60 ) is achieved. 
         [0036]    By the aforementioned configuration, operation of the present invention is illustrated in  FIGS. 1 ,  6 , and  12 - 14 . The user first adjusts the distance of the winding bearing set ( 20 ) according to the external diameter of the spiral coil ( 65 )( 65 A). Detailed, the user rotates the adjustment pole ( 32 ) of the adjustment module ( 30 ) to make the adjustment pole ( 32 ) drive the moving base ( 33 ) to move, then to rotate the rotation axial base ( 25 ) through the linking pole ( 34 ) to make the auxiliary shaft ( 27 ) on the rotation axial base ( 25 ) move opposite to the driving shaft ( 22 ).

When the documents ( 60 )( 60 A) with spiral coils ( 65 )( 65 A) are placed in the ditch ( 16 ) of the lid ( 15 ), the driving device ( 51 ) of the longitudinal cut module ( 40 ) is activated to rotate the cam ( 52 ) on the mechanic base ( 41 ), and synchronously operates the first and the second driving poles ( 55 )( 56 ) via the crank ( 54 ) eccentrically pivoted to the cam ( 52 ) to respectively operate the movable blade ( 452 ) of the longitudinal cut base ( 45 ), relative to the stationary blade ( 451 ), to cut the extension portion ( 66 ) of the spiral coils ( 65 )( 65 A), and to operate the movable jaw ( 442 ) of the bending base ( 44 ), relative to the stationary jaw ( 441 ), to bend the extension portion ( 66 ) of the spiral coils ( 65 )( 65 A) as a bended portion ( 67 ) to prevent the spiral coil ( 65 )( 65 A) from departing from the document ( 60 )( 60 A). 
         [0038]    The user can rotate the rotation pole ( 46 ) of the longitudinal cut module ( 40 ) to operate the bending base ( 44 ) screwed on the rotation pole ( 46 ) for fine tuning the distance between the bending base ( 44 ) and the longitudinal cut base ( 45 ) and fine tuning the length of the bended portion ( 67 ). 
         [0039]    The present invention is able to adjust the distance between the driving shaft ( 22 ) and the auxiliary shaft ( 27 ) of the winding bearing set ( 20 ) by the adjustment module ( 30 ) to meet the spiral coil ( 65 ) with different external diameter. The longitudinal cut module ( 40 ) changes the length needed to be cut according to the external diameter of the spiral coil to make the winding bearing set and the longitudinal cut module synchronously meet spiral coil with the same diameter. The spiral coil is convenient to be driven into the holes drilled on the document to enhance supplementary value of products and enhance competition superiority and economic benefit 
         [0040]    To conclude, the present invention is a very good creation, and it or similar products or publications in the same technical field cannot be found. The present invention also improves the performance. Thus, the present invention conforms to rules of novelty and non-obviousness of patent examination, and the present invention shall be allowed as soon as possible.
