     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0018]    Referring  FIGS. 1 through 4 , a screwdriver kit in accordance with the preferred embodiment in the present invention includes a main body  10 , a linkage  20 , a bit storage member  30 , a cap member  40 , a locking member  50  and a chunk member  60 . 
         [0019]    The main body  10  includes a first end  11  and a second end  12 . The first end  11  is adapted for connecting to a tool such as a chunk or things like that. In this case, the chunk member  60  is detachably installed to the first end  11  and includes a bore  61  formed thereon and a magnetic portion  62  provided in the bore  61 . The bore  61  is adapted for receiving to a tool such as a screwdriver bit of things like that. The magnetic portion  62  is adapted for attaching with the tool which is received in the bore  61 . 
         [0020]    A column  13  longitudinally extends from the second end  12  of the main body  10  and includes an opening  131  longitudinally formed therein. The opening  131  communicates with the interior of the main body  10 . A transverse cross-section of the column  13  is preferably hexagon, and a transverse cross-section of the opening  131  is preferably hexagon. A slot  132  is formed on the outer periphery of the column  13  and adjacent to the extremity of the column  13  opposite to the second end  12  of the main body  10 . The slot  132  is preferably U-shaped and has two legs. The legs of the slot  132  and the opening  131  are in communication with each other. A U-shaped fastener  133  is received in the slot  132  and inserted into the opening  131 . 
         [0021]    An engaged portion  14  are provided around the column  13  and against the second end  12 . A diameter of the engaged portion  14  is smaller than that of the main body  10 . Numbers of engaged recesses  141  are longitudinally formed on the outer periphery of the engaged portion  14  and space from each other. A slide rail  142  and three notches  143  are transversely formed on the outer periphery of the engaged portion  14 . And the slide rail  142  and the notches  143  are closer to the second end  12  than the engaged recesses  141 . The slide rail  142  communicates with the opening  131 . A longitudinal cross-section area of the slider rail  142  is larger than the transverse cross-section area of the opening  131 . The length of the slider rail  142  is smaller than the diameter of the engaged portion  14 , and the slider rail  142  has one opening (not numbered) which is open to the periphery of the engaged portion  14 . 
         [0022]    The linkage  20  is slideably disposed in the opening  131 . The cross-section of the linkage  20  which is preferably hexagon corresponds to that of the opening  131  so that the linkage  20  cannot rotate with respect of the opening  131 . The linkage  20  has a first end and a second end. An annular groove  21  is provided on the first end of the linkage  20  adjacent to the main body  10 . A cross-section of the annular groove  21  is preferably circular. A first elastic element  22  is disposed in the opening  131  and sandwiched between the linkage  20  and the chunk member  60 . The fastener  133  is inserted into the opening  131  through the slot  132  and enables to grip on the annular groove  21  so that while the linkage  20  is pressed by the first elastic element  22  outwardly with respect of the opening  131 , the fastener  133  is provided to restrict the linkage  20  for preventing the linkage  20  from detaching from the opening  131 . 
         [0023]    The bit storage member  30  includes a hexagon coupled hole  31  formed on the center thereof. The bit storage member  30  is mounted on the column  13  via the coupled hole  31 . Numbers of first storage holes  32  and a second storage hole  33  are arranged on the bit storage member  30  around the coupled hole  31 . Each of the first storage holes  32  is preferably hexagon. The first storage holes  32  are adapted for receiving various bits, and the second storage hole  33  is adapted for receiving a bit shank (not shown). A receptacle  144  is formed on the engaged portion  14  and corresponds to the second storage hole  33  so that the bit shank can be inserted through the second storage hole  33  and the receptacle  144  into the interior of the main body  10 . A diameter of the bit storage member  30  is smaller than the diameter of the main body  10 . Numbers of engaged recesses  34  are formed on the outer periphery of the bit storage member  30  annularly and respectively correspond to and similar to the engaged recesses  141  of the main body  10 . At least one of longitudinal extensions  134  is formed on the outer periphery of the column  13  and adjacent to the second end  12  of the main body  10  as to prevent the bit storage member  30  from abutting against the main body  10 . 
         [0024]    The cap member  40  is able to be attached with the engaged portion  14  of the main body  10 , and the linkage  20  is received in the cap member  40 . A compartment  41  is defined in the cap member  40 , and a connected hole  411  is formed in the bottom of the compartment  41 . The second end of the linkage  20  is installed to the connected hole  411 . The cap member  40  is slideable along the linkage  20  between a first position and a second position. In the first position, the cap member  40  is attached with the main body  10 . In the second position, the cap member  40  is detached from the main body  10 . Furthermore, numbers of studs  412  are formed on the interior side of the compartment  41  and correspond to the engaged recesses  141  of the main body  10  as to couple the cap member  40  to the main body  10  as the cap member  40  is in the first position. Alternatively, the cap member  40  can be adapted for storing bits or a bit shank as to omit the bit storage member  30 . 
         [0025]    Referring to  FIGS. 2 and 5 , the locking member  50  is adapted for restricting the cap member  40  in the first position and includes a clip  51 , a detent  52  and a second elastic element  53 . The clip  51  is preferably C-clip and has a gap  511  and three notches  512 . The width of the gap  511  is same as the width of the slide rail  142 , and the notches  512  respectively correspond to the notches  143  as to couple the clip  51  on the outer periphery of the engaged portion  14  for preventing the engaged portion  14  from exposing outside. The detent  52  is slideably disposed in the slide rail  142  and has a first end and a second end. A through-hole  521  is defined on the detent  52  between the first and second ends of the detent  52  and corresponds to the opening  131 . The second elastic element  53  is provided between the second end of the detent  52  and the slide rail  142  as to engage the through-hole  521  of the detent  52  with the annular groove  21  of the linkage  20 . Hence, the cap member  40  is fixed to the first position and attached with the main body  10 . A restricting portion  522  is provided on the detent  52  adjacent to the second end of the detent  52  and engaged with a receiving hole  145  formed on the main body  10  as to prevent the detent  52  from detaching from the slide rail  142 . In addition, cooperation of the outer periphery of the second end of the detent  52  and the clip  51  exactly form a whole ring profile for aesthetic. 
         [0026]    Referring to  FIGS. 6 through 8 , after pressing the detent  52  toward the main body  10 , the through-hole  521  of the detent  52  is disengaged from the annular groove  21  and the linkage  20  is not restricted by the detent  52  any more. And then, the first elastic element  22  pushes the linkage  20  to detach from the main body  10  and the cap member  40  is driven to move to the second position from the first position till the fastener  133  is engaged with the annular groove  21 . Therefore, the fastener  133  is adapted for preventing the linkage  20  from detaching from the opening  131 , and in the same time, the bit storage member exposes outside so that it is easy and convenient to take the bits or the bit shank to connect with the chunk member  60  (as shown in  FIG. 6 ). 
         [0027]    Thus since the invention disclosed herein may be embodied in other specific forms with out departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiments described herein are to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come with the meaning and range of equivalency of the claims are intended to be embraced therein.
