BACKGROUND OF INVENTION 
       [0001]    1. Field of the Invention The present invention relates generally to a golf bag, and more particularly to an innovative one which can reduce the transport space and facilitate disassembly. 
         [0002]    2. Description of Related Art 
         [0003]    The conventional golf bags are usually assembled in the factory and then transported to the merchants or distributors for sale; however, the fixed volume will take much space for transportation and packaging, but also cause higher freight; moreover, common consumers can only select their preferred or appropriate bags according to individual demands, but cannot assemble by themselves, which is an important factor for higher golf bag cost and sales price. 
         [0004]    For this reason, golf bags that can be assembled by merchants and distributors have been developed with smaller packing volume, more transportation capacity and less transportation cost (packaging and shipping by parts, not by finished products). Yet, the support bar connected between the upper frame and base of conventional self-assembly golf bag is designed into a long bar or plug-in type. The length of long bar type support bar is fixed but may also affect the reduction degree of packing volume, the plug-in type support bar can effectively reduce the packing volume, but it is likely to result in loosening and failure due to lack of strength. In fact, most of existing golf bag support bars are represented by abovementioned two types, and recently, a screwed type is designed, but the screwed portion must be made of metals to ensure the robustness with higher fabrication cost. 
       SUMMARY OF THE INVENTION 
       [0005]    The main purpose objective of the present invention is to provide a detachable golf bag, of which the support bars are incorporated into a multi-section structure via a coupling device, making it easy to disassemble and reduces the packing volume and transportation cost. 
         [0006]    To this end, the present invention provides a detachable golf bag, which comprising: an upper frame, a base, several support bars and a rack; each support bar contains a first bar body, a second bar body and a coupling device; the coupling device contains a first coupling block, a second coupling block and an moveable sleeve; of which the first and second coupling blocks are separately set at one end of the first and second bar bodies, and the moveable sleeve is movably set on the outer side of the second bar body and the second coupling block; a first clamping part is set at one end of the first coupling block, and a second clamping part set at one end of the moveable sleeve.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0017]    Firstly, referring to  FIGS. 1-5 , the detachable golf bag  10  comprises: an upper frame  12 , a base  14 , three support bars  16  that can be detachably connected with the upper frame  12  and base  14 , as well as a rack  18  that can be detachably connected with the upper frame  12  and base  14  to position the golf bag  10  vertically on the ground (e.g. bag body, strap); the abovementioned upper frame  12 , base  14 , support bar  16  and rack  18  are assembled almost the same way as conventional golf bag. But, the golf bag  10  of the present invention is characterized by that: 
         [0018]    The support bar  16 , plugged detachably in the socket  21  between the upper frame  12  and base  14 ; it comprises of a first bar body  22 , a second bar body  24  and a coupling device  26 ; the coupling device  26  contains a first coupling block  28 , a second coupling block  30  and an moveable sleeve  32 ; the first and second coupling blocks  28 ,  30  are sleeve-shaped with one open end, and set securely at ends of the first and second bar bodies  22 ,  24 ; a first abutment portion  34  and a second abutment portion  36  are separately set at corresponding ends of the first and second coupling blocks  28 ,  30 ; the first abutment portion  34  is of a convex surface and the second abutment portion  36  is of a concave surface mated with the first abutment portion  34 ; convex first clamping parts  38  are separately set at two ends of the first coupling block  28  correspondingly to the first bar body  22 ; the moveable sleeve  32  is of a tubular shape with two open ends, and movably set on the outer side of the second bar body  24  and the second coupling block  30 ; and second clamping parts  40  are separately set at two ends correspondingly to the second coupling block  30 ; the second clamping part contains a guide slot  42 , a caulking groove  44  and a clamping block  46 ; the guide slot  42  is set into the inner wall at one end of the moveable sleeve  32  and extended to the other end; the caulking groove  44  is set through the moveable sleeve  32  to the guide slot  42 , and the clamping block  46  is set convexly at one side of the inner wall of the caulking groove  44 . 
         [0019]    Moreover, the rack  18  comprises of two support rods  48  pivoted to the upper frame  12 , an elastic frame  50  connected with two metal wires, and one end is movably connected with two support rods  48 , a plug-in unit  52 , set at the other end of the elastic frame  50  and detachably set in a slot  54  set at one side of the base  14 . 
         [0020]    With this design, the golf bag  10  of the present invention is used in the same way as the conventional one; and its features and efficacy are as follow: 
         [0021]    Based on the detachable structure of support bars  16 , rack  18 , upper frame  12  and base  14 , the golf bag  10  has efficacy of reducing the packing volume and the transport cost (not assembled into finished products). 
         [0022]    Particularly when it is intended for assembly of the support bars  16 , the first and second bar bodies  22 ,  24  are separately inserted into the socket  12  between the upper frame  12  and base  14 , then the first and second abutment portions  34 ,  36  of the first and second coupling blocks  28 ,  30  are abutted as shown in  FIG. 6 . Next, the moveable sleeve  32  is moved to cover the first and second coupling blocks  28 ,  30 , such that the first clamping parts  38  could slide into the guide slot  42  to enter into one end of the caulking groove  44 , as shown in FIGS.? and  8 . Thus, the moveable sleeve  32  is rotated such that the first clamping part  38  is abutted to the other end of the caulking groove  44 ; moreover, the moveable sleeve  32  is pulled backwards a little, so the first clamping part  38  is abutted to the clamping block  46  to prevent the first clamping part  38  disengaging from the caulking groove  44 ; this could complete the assembly of support bars  16  more easily and quickly. Certainly, the support bars  16  could be disassembled in reverse steps. 
         [0023]    The support bars of the golf bag of the present invention are incorporated into a multi-section structure via a coupling device, so it has efficacy of reducing the packing volume and transport cost of the golf bag, but also enables easy and quick assembly; besides, the abutting of the first and second coupling blocks can be fixed by the moveable sleeve with robust state; therefore, there is need to use metal material for the first and second coupling blocks and the moveable sleeve. Compared to the conventional multi-section or screwed support bars, the present invention has obvious efficacy. 
         [0024]    Referring to  FIG. 9 , the first and second coupling blocks  28 ,  30  of the support bars  16  in the present invention can also be designed to be pivotally connected by a pivot seat  58  and a pivot lug  60 . Based on this, the first and second bar bodies of the support bars  16  are connected for quicker assembly. 
         [0025]    Referring also to  FIG. 10 , the plug-in unit  52  of the rack  18  can also be detachably inserted into a slot  64  of a drive plate  62  on the base  14 .
