BACKGROUND OF THE INVENTION  
       [0001]     (a) Technical Field of the Invention  
         [0002]     The present invention relates to a winding mechanism, and in particular, to a press-button type winding mechanism which can secure wire at a desired length and portion, and retract the wire to its original position.  
         [0003]     (b) Description of the Prior Art  
         [0004]     Cable and wirings are to be wound at a distance and clipped with a device so as to provide an appropriate length to the user. In order to provide a mechanism which can appropriately deliver a desired length and secured automatically at that length, and release the wire from the secured position by just pressing the button, the conventional winding mechanism employs a steel beads and spiral spring to control the wire so that a desired wire length can be secured after it is retracted. The drawback of the conventional winding mechanism is that a rail positioning structure is needed. Therefore, a single winding operation will fully retract the wire. In other words, the wire cannot be subsequently wound or retracted. Another drawback of the conventional winding mechanism is that the pulled out length of the wire cannot be precisely controlled.  
         [0005]     Accordingly, it is an object of the present invention is to provide a press-button type multi-stage winding mechanism which mitigates the above mentioned drawbacks.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0018]     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.  
         [0019]     Referring to  FIGS. 1 and 2 , there is shown a press-button type multi-stage winding mechanism comprising a top cover  1 , a button  2 , a spiral spring  3 , a sliding disc  4 , wire  5 , a winding disc  6 , a bottom disc  7  and a bottom cover  8 . The spiral spring  3  is placed within the edge seat  41  of the sliding disc  4 , and the center shaft  71  of the bottom disc  7  is provided with a through hole  42 , and the inner end  31  of the spiral spring  3  is secured at the center shaft  71  of the bottom disc. The outer end of the spiral spring  3  is a hook section  32  engaged at the inner wall of a clipping plate  411  of the edge seat  41  of the sliding disc such that the inner end  31  and the hook section  32  are respectively restricted by the bottom disc  7  and the sliding disc  4 . Thus, no matter the sliding disc  4  rotates in a positive or a negative direction, the spiral spring  3  can be urged to a tightening or a releasing state.  
         [0020]     The sliding disc  4  and the winding disc  6  are connected and the center shaft  71  passes through the winding disc  6  to the sliding disc  4  for the engagement of the spiral spring  3 . The space of the edge seat  41  is used for the holding of the spiral spring  3 , and the external circumferential face of the edge seat  41  is provided with one or more than one positioning block  43 . The number of the positioning blocks  43  will decide the location and the positioning distance of the winding disc  6  at each rotation. Thus, the wire can be precisely controlled.  
         [0021]     Referring to  FIGS. 2, 3 ,  4 ,  5  and  8 , the winding disc  6  has a positive direction edge seat face  61  and a negative edge seat face  62 , wherein the positive direction edge seat  61  is engaged by the plurality of the engaging button  612  on the winding seat  611  and the engaging hole  44  of the sliding disc  4 , and the positive wire  5  surrounds the external circumferential face of the winding seat  611  such that the positive direction wire  5  is wound between the sliding disc  4  and the winding disc  6 . Next, the positive direction wire  5  passes through the through hole  613  of the winding seat  611  to the negative direction edge seat  62  and is wound at the fastening plate  614  of the reverse face of the edge seat  62 , and then passes through the bottom slot  711  and is positioned by the bottom engaging slot  72  at the bottom disc  7  so that the end head is secured. Thus, the intersecting point of the positive direction wire and the negative direction wire is fastened such that when the positive direction wire  5  is extended, the negative direction wire  5  is not affected. Thus, a single pulling function of the wire is precisely achieved.  
         [0022]     When the positive direction wire  5  is pulled, the negative direction wire  5  is at a releasing state. When the positive direction wire  5  is restored to its original position, the negative direction wire  5  is rotated tightly. The positive direction wire  5  is wound based on the winding seat  611 , and the negative direction wire  5  is wound based on the center shaft  71 , wherein their rotating shaft direction of a winding are different, therefore the total length of the positive direction wire  5  shall longer than the negative direction wire  5 .  
         [0023]     As shown in  FIG. 6 , the positioning function is depending on the position of the sliding disc  4  and that of the button  2 . The button  2  is pivotally mounted at the pivot hole  21  on the top cover  1 , and the front direction of the top cover  1  has a blocking plate  11  engaging a spring  111  so that the button  2  has a restoring. function by pressing the button  2 .  
         [0024]     An urging rod  22  is provided at the front of the button  2  and the position is corresponding to the positioning block  43  at the circumferential face of the sliding disc  4 . As shown in  FIG. 7 , when the button  2  is depressed, depending on the depressing force of the button  2 , the urging rod  22  is slightly swung this will cause either a positioning function. or releasing from a positioned state. Thus, when the winding disc  6  is pulled out in a clockwise direction, the relationship between the urging rod  22  and the positioning block  43  is that the pushing away of the urging rod  22  will not cause a positioning state. When the wire  5  is pulled to a desired length and is then released, the action of the spiral spring  3  will cause the winding disc  6  to rotate in a reverse direction. At this instance, the urging rod  22  of the button will urge the positioning block  43  which is first restored back to the original direction. Thus, this wire  5  is positioned. To allow the pulled wire  5  to return to its original position, the button  2  is depressed. This will cause the urging rod  22  to swing to release from at urging position and the winding disc  6  will rotate to pull back the wire  5 . In addition, while in the course by pulling the wire  5 , the button  2  can be used to control precisely to subsequently wind the traction line.  
         [0025]     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.  
         [0026]     While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
