BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention generally relates to a reel, and more particularly, to an improved structure of a reel, which is used for control of reeling in and out the cords or wires of manifold devices such as electronic products, computers, phones, and communication equipment. 
         [0003]    2. Description of Related Art 
         [0004]    As the technology is progressed ceaselessly, the structures of computers, electric and communication equipment are developed to meet the requirements of the present market. However, it is always inconvenient to store the cords or wires of these devices. To solve the problem, various kinds of reels are provided to collect the cords or wires and control the length of cords or wires in use. 
         [0005]    Referring to  FIG. 1 , a reel  10  is utilized by pulling out the wires or cords  101  at two ends with hands, which is single-staged. That is, the reel  10  is not fixed until the cords thereof are completely drawn out. In order to roll up the cords  101 , users need to drag and release the cords  101  at two ends simultaneously, and thereby the cords  101  are collected automatically. Another kind of reel  10  belongs to a multi-staged reel, in which the cords  101  are drawn out and fixed in multiple stages. Though the cords  101  can be fixed in multiple stages while being pulled, it is difficult to define the length of the cords  101  and it is still unfavorable to reel out the cords  101  at two ends concurrently because the process needs to be repeated several times for entire collection of the cords  101 . 
         [0006]    In view of the aforesaid disadvantages, an improved structure of a reel that satisfies the concerns of convenience and utility is investigated and provided in the application. 
       SUMMARY OF THE INVENTION 
       [0007]    It is one object of the invention to provide a structure of a reel. The reel includes two cords or wires, one of which is reeled in or out concurrently as the other is drawn out. Additionally, the length of cords or wires is adjusted to a desired level in multiple stages if necessary, and the cords or wires of such reel are collected quickly and smoothly.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0014]      FIG. 2  is a perspective and exploded diagram illustrating various components of a reel structure according to an embodiment of the invention. As shown, the reel structure includes a base  20  with two openings  20   a.  An axial pillar  201  is disposed on the base  20 , and a column  202  is spaced apart from the axial pillar  201 . The base  20  further includes a plurality of plugs  203 , a support  204  with a groove disposed in the middle of the base  20 , and a bulged ring  204   a.    
         [0015]    A substantially V-shaped spring  30  is also provided. 
         [0016]    A movable arm assembly  40  includes a movable arm  401  equipped with an axial hole  401   a  in the lower portion thereof. A spring arm  402  and a stud  402   a  are disposed on one side of the movable arm  401 . 
         [0017]    A clasper  50  with a concave portion in the middle is provided. The clasper  50  further includes a plurality of fastening holes corresponding to the axial pillar  201 , the column  202  and the plugs  203 . 
         [0018]    A rotating disc  60  is provided with an axial hole  601  in its center. A surrounding wall  602  is disposed on the upper portion of the rotating disc  60 , and the wires or cords  70  are wedged therein. These two cords  70  are wound along the outside of the surrounding wall  602  in the same direction. A coil spring  80  is positioned in the middle of the surrounding wall  602 . Referring to  FIG. 3 , a bugled ring  603  and a bugled track assembly  604  are disposed at the middle bottom of the rotating disc  60 . The bugled track assembly  604  includes two cambered movable tracks  604   a,  two concave switchable tracks  604   b  and two bumps  604   c  connected therewith. The switchable track  604   b  further includes a counter surface  604   b   1  for pushing. 
         [0019]    In addition, there is a cap  90  with two openings  901 . 
         [0020]    The axial pillar  201  on the base  20  is inserted into the axial hole  401   a  of the movable arm assembly  40 . One end of the spring  30  is attached to the column  202  of the base  20 , and the other end is coupled to the stud  402   a  disposed on the spring arm  402  of the movable arm assembly  40 . The fastening holes of the clasper  50  respectively mate with the axial pillar  201 , the column  202  and the plugs  203 , so as to avoid the separation of the movable arm assembly  40  from the spring  30  and to allow some movement therebetween. The support  204  on the base  20  is inserted into the axial hole  601  of the rotating disc  60  correspondingly such that the rotating disc  60  is rotatable about the support  204 . The inner portion of the coil spring  80  disposed in the middle of the surrounding wall  602  on the rotating disc  60  is inset in the groove of the support  204 . The cap  90  then covers the present structure. As a result, the cords  70  protrude the openings  901  of the cap  90  and the openings  20   a  of the base  20  to constitute a reel  2000 . 
         [0021]    Referring to  FIG. 4 , while the rotating disc  60  is turned by pulling the cord  70  on one side of the reel  2000 , the cord  70  on the other side is reeling out synchronously. Because the movable tracks  604   a  and the bumps  604   c  of the track assembly  604  on the rotating disc  60  rub against and push each other constantly to move the tip of the movable arm  401  of the movable arm assembly  40  aside, the rotating disc  60  continues rotating smoothly. Therefore, the cords  70  can be drawn out in determined length. Meanwhile, the coil spring  80  disposed in the middle of the surrounding wall  602  on the rotating disc  60  is reeled in towards the center, so as to create a reversed tension. Now referring to  FIG. 5 , after the cords  70  with determined length are drawn out, the rotating disc  60  is turned again by pulling the cord  70  gently. The bumps  604   c  of the track assembly  604  thus pass the tip of the movable arm  401 . Thereafter, the cord  70  is set free to release the reversed tension from the coil spring  80  so that the rotating disc  60  is turned in an opposite direction, and the bump  604   c  leans against the tip of the movable arm  401  and then fixed. Referring to  FIG. 6 , in order to rolling up the cords  70 , the cord  70  is pulled to make the movable tracks  604   a  rub against the bumps  604   c  of the track assembly  604  on the rotating disc  60 . When the rotating disc  60  is rotated and the switchable track  604   b  is not blocked by the tip of the movable arm  401 , the friction between the tip of the movable arm  401  and the movable track  604   a  is converted to the counterforce force arising from the interaction between the movable arm  401  and the spring  30 . Thereby, the movable arm  401  springs into the switchable track  604   b.  Then, the cord  70  is set free to release the reversed tension from the coil spring  80  so that the rotating disc  60  is turned in an opposite direction. The counter surface  604   b   1  of the switchable track  604   b  of the track assembly  604  pushes the tip of the movable arm  401  to form a space for the smooth progress of the movable tracks  604   a  and the bumps  604   c  of the track assembly  604 . Accordingly, the rotating disc  60  is quickly rotated to wind the cords  70 . 
         [0022]    In accordance with the description above, the reel structure possesses the desirable benefits and effects. The structure is not known to the public, and has utility and novelty. It is appreciated if the application is examined and granted. 
         [0023]    The aforementioned embodiments of the present invention are intended to be illustrative only. Numerous alternative embodiments may be devised by those skilled in the art without departing from the scope of the following claims.
