It&#39;s convenient to implement the outward rotation of any tool to drive the nuts or screws; after use, the respective tool is collected toward the case for suitable portability. 
         [0003]    However, there is no position design in the conventional foldable tool kit. The in-use tool with poor positioning function is disadvantaged of coming adrift affects the implementation thereof. 
       SUMMARY OF THE INVENTION 
       [0004]    It is therefore a primary object of the present invention to provide a foldable tool kit, which is capable of positioning a tool at a specific angular position after rotation. 
         [0005]    To achieve the above and other objects, a foldable tool kit for positioning the tool in accordance with the present invention includes a case, which has two lateral sideboards paralleled to each other. At least one pivot shaft is arranged between the two sideboards. Plural of tools are pivotally connect to the pivot shaft between two sideboards via a pivot end thereof so as to meet the turn-free rotation. Each tool has at least one retaining portion formed on a lateral face of the pivot end thereof. Plural of orientation rings, each orientation rings has at least one engaging portion formed on at least one lateral face thereof; the orientation rings are disposed on the pivot shaft and arranged among the tools but fails to rotate on the pivot shaft. 
         [0006]    Therefore, the retaining portion of the tool mates with the engaging portion of the orientation ring while the tool in use and the tools are provided with a positing point of rotation. 
         [0007]    Preferably, each orientation ring is formed with a sleeve hole in order to sleeve onto the pivot shaft. An exterior perimeter of the pivot shaft and the sleeve hole of each orientation ring are non-circular shaped, and it enables the orientation rings engage with the pivot shaft.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0027]    Please refer to  FIGS. 1 and 2 , the foldable tool kit  10  for positioning the tool of a first embodiment in accordance with the present invention includes a case  20 , a plurality of tools  30  pivotally connected to an end or two ends of the case  20 , and a plurality of orientation rings  40 . In this embodiment, two ends of the case  20  are pivotally connected with several tools  30 . 
         [0028]    The case  20  could be configured of any shape and type, and at least include two sideboards  22  parallel to and distanced from each other. Two ends of each sideboard  22  is formed with a non-circular connection hole  24 , such as hexagonal, tetragon, polygon, specific forms or the likes, but not restrained. 
         [0029]    With respect to  FIG. 3 , two pivot shafts  25  are provided, and each includes a screw rod  26  with an inner screw hole  261 , and a screw member, such as a screw  27 . An exterior perimeter of each pivot shaft  25  (, the screw rod,) is of non-circular configuration in order to correspond to the shape of the connection hole  24  of the sideboard  22 . By fastening the screw rod  26  to the screw  27 , the two pivot shafts  25  dispose at the connection holes  24  of the two sideboards  22 , as illustrated in  FIG. 3 , a head of the screw rod  26  abuts against one sideboard while the screw  27  abuts against the other one. The exterior perimeter of each pivot shaft  25  engages with the hole wall of each connection hole  24  to block the pivot shaft  25  from rotation. 
         [0030]    Each tool  30  is rod-liked. An end of a rod body  31  of each tool  30  is defined as an operation end  32 , and the other end is defined as a pivot end  34  formed with a pivot hole  35 . The operation ends  32  of the tools  30  are shaped with various sizes and configurations, such as bits of hexagonal, crisscross, chisel or polygon forms, for meeting different screw members. The operation end  32  is not limited to bits but also other parts, such as a polygon sleeve hole for the screw nuts. The pivot end  32  of each tool  30  is annular and formed with quantity-predetermined, such as four, retaining portions  36  at a lateral face thereof. The retaining portions  36  are arranged in a circle order and spaced at a right angle, and to be in concentricity with the pivot hole  35 . The pivot ends  34  of the tools  30  respectively sleeve onto the pivot shaft  25  between the two sideboards  25 , and the tools are of turn-free rotation on the pivot shaft. 
         [0031]    A central of each orientation ring  40  is formed with a non-circular sleeve hole  42 , such as hexagonal or tetragon forms, in order to correspond to the exterior perimeter of the pivot shaft  25 . Each orientation ring  40  has a plurality of engaging portions  44  at a lateral face thereof, as in  FIG. 4 . The engaging portions  44  are in concentricity with the sleeve hole  42 . The orientation rings  40  are respectively sleeved onto the pivot shaft  25 , and the orientation rings are arranged with the tools  30  in a staggered order. The hole wall of the sleeve hole  42  fits to engage with the exterior perimeter of the pivot shaft  25 , as illustrated in  FIG. 5 , the orientation ring  40  thereby are blocked from rotating about the pivot shaft  25 . In the embodiment, the quantity of the orientation rings  40  are as same as that of the tools  40 , and the engaging portions  44  of each orientation ring  40  match the retaining portions  36  of the respective tool  30 . Referring to  FIG. 3 , the engaging portions  44  and the retaining portions  36  are convex-concave designed. The engaging portions  44  are convex while the retaining portions  36  are concave, vice versa. Therefore, the retaining portions  36  and the engaging portions  44  mate with each other for engagement, as in  FIG. 6 . It&#39;s reasonable that the quantity of the retaining portions  36  of each tool  30  is no need to be the same as that of the engaging portions  44  of each orientation ring  40 . 
         [0032]    Because the orientation ring  40  is unable to rotate, the tools  40  could be positioned at specific angular positions when the retaining portion  36  mates with the engaging portion  44 . 
         [0033]    With respect to  FIG. 7 , the tools are able to be folded and collected into the case  20 , stretched outwards raging a right angle as shown by the solid line, or stretched outwards raging a straight angle as shown by the imagination line. The retaining portion  36  mates with the engaging portion  44  so as to posit the respective tool  30 . Therefore, the tool is posited at specific/different angular positions while folding or stretching, and it&#39;s convenient for users. When the retaining portion  36  departs from the engaging portion  44  while the tool  40  rotates to get away from the positing position, a push resilient resistance between the tool  30  and the corresponding orientation ring  40  is created. When the retaining portion  36  fit to mate with the engaging portion  44  while the tool  40  rotates to meet the positing position, a steady positing between the tool  30  and the corresponding orientation ring  40  is created, and for user, the resilient positing implementation is offered thereby. 
         [0034]    In addition, each pivot shaft  25  could be further applied with a resilient member, such as a resilient washer  28 , to enable the tools  30  keep flexible contact with the orientation rings  30 . Nevertheless, the resilient washer  28  is not necessary but the elastics it provides could be substituted by sideboards, which is of flexibility. 
         [0035]    There are more than two tools  30  are provided to each end of the case  20  according to the present invention. By the mating design due to the incapability of rotation of the orientation ring  40 , the tool is able to position while rotating. According to the design of the invention, the position function for each single tool is provided; no matter how many tools are set. 
         [0036]    Referring to  FIGS. 8 and 9 , a foldable tool kit  50  of a second embodiment according to the present invention is disclosed. The tools  30  and the orientation rings  40  are as same as those in the first embodiment and continue to use their numerals. 
         [0037]    In the embodiment, an end of each pivot shaft  65  connects to a lateral face of a first sideboard  62 . Two ends of a second sideboard  62   a  are respectively formed with a connection hole  64 . A screw  66  is applied to screw to an inner screw hole  651  of a free end of each pivot shaft  65 ; to attach the free end of each pivot shaft  65  to the second sideboard  62   a;  and to assembly the sideboard and the pivot shaft to accomplish the embodiment. The tools  30  and the orientation rings  40  are similarly arranged to the two pivot shafts  65  so that the tools  30  are able to be positioned after rotation. Each connection hole  64  of the second sideboard  62   a  could be non-circular or circular shaped. Similarly, the connection hole  24  of a second sideboard  22   a  in the first embodiment is also non-circular or circular shaped. 
         [0038]    In the mentioned embodiments, the retaining portions of each tool are formed at the same lateral face, which means the retaining portions are set towards the same direction. Please refer to  FIG. 10 , a foldable tool kit  70  of a third embodiment according to the present invention is disclosed. Except the previous ones, the arrangement between the tools and the orientation rings could be implemented corresponding to this embodiment. There is one or two orientation rings  90  placed between two tools  80 ,  80 ′, which is in pair. The retaining portions  86  of the paired tools  80 ,  80 ′ face to each other; the engaging portions  94  of the orientation ring or rings  90 , that is/are positioned between the two tools  80 ,  80 ′, mate with the retaining portions of the paired tools. 
         [0039]    If only one orientation ring  90  is applied between the two tools  80 ,  80 ′, the two tools  80 ,  80 ′ are sharing the same orientation ring  90 , as illustrated in  FIG. 11 . Meanwhile, two lateral faces of the orientation ring  90  are arranged with the engaging portions  94  for mating the retaining portions  86  of the two tools  80 ,  80 ′. In the same manner, the engaging portions  94  are concave or convex. 
         [0040]    With respect to  FIGS. 12 to 14 , a foldable kit  100  of a fourth embodiment according to the present invention is disclosed, in which the designated numerals are continued. The foldable kit  100  includes a case  20 ′, a plurality of tools  30 ′, and plurality of orientation rings  40 ′. Each tool  30  are pivotally connected to a pivot shaft  25 ′ of the case  20 ′ via an annular pivot end  34 ′ thereof; the retaining portions  36 ′ of each tool  30 ′ mate with the engaging portions  44 ′ of each orientation ring  40 ′ in order to position the tool. 
         [0041]    The structure of this embodiment is substantially similarly to the tool kit  10  of the first embodiment; the difference is the configurations of the tools  30 ′ slightly differ from those of the tools  30 . 
         [0042]    With respect to  FIGS. 15 to 18 , a foldable kit  110  of a fifth embodiment according to the present invention is disclosed, in which the designated numerals are continued.
