FILED OF THE INVENTION 
     This invention relates to a structural combination of a tool box with a fuel tank, mainly comprising a tool box structure and a fuel tank structure, a simple and robust correlative combination for consolidated storage. 
     BACKGROUND OF THE INVENTION 
     It is a well-known fact that the automobile trunk is generally used for storing assorted materials, such as the battery rescue cable, the pressure gauge, the tire hand pump, any tool box, even the empty fuel tank for an emergent purchase of fuel when it runs short. However, the tool box and the fuel tank are generally in separate form, never in a combined structure in the market. It requires a larger space to store two items than one. 
     The inventor has been working for years on the design of the tool box case and was inspired to shift attention to the research, design and fabrication of such a combination of a tool box with a fuel tank. 
     The main object of the invention is to provide a structural combination of a tool box with a fuel tank which is easy and simple to integrate into the tool box to become an integral storage device without occupying too much space. 
     Another object of the invention is to provide a structural combination of a tool box with a fuel tank in which the tool box permits ease for opening and closing while taking off the tool out of the tool box. The tool box stands firmly with practical application. 
     Another object of the invention is to provide a structural combination of a tool box with a fuel tank in which the fuel tank permits to be separated from the tool box for independent use. 
     SUMMARY OF INVENTION 
     The invention concerns a structural combination of a tool box with a fuel tank, mainly comprising a fuel tank which is sandwiched between the open space of a split tool box for the consolidated storage. In application, the fuel tank can be taken off from the tool box when it is necessary to fill it with fuel reserved as a stand-by fuel. The tool box stands upright for opening and closing, expedient to take off and put back the tool. 
     The design utilizes two half tool box casings, the left half box casing and the right half box casing with an upright panel standing between them. The upright panel works to hold on the fuel tank. When two half box casings are closed, the fuel tank is resolutely sandwiched between to form an integral part for consolidated storage space. The fuel tank allows to be taken off for separate use. When the tool box is opened, it stands uprightly on the ground, convenient for accessing to the tool. 
     This invention mainly comprises a tool box structure and a fuel tank structure, a simple and robust correlative combination for consolidated storage. The tool box stands independently in opening and closing operation, which is easy for the operator to take off and put back the tool, and the fuel tank permits to be separated from the combination for independent use. 
     The technical applications, features and efficiency of the invention will be explained in great detail with the aid of embodiments as illustrated in the drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     As shown in the figures, the combination of a tool box with a fuel tank of the invention mainly constitutes a tool box structure  10  and a fuel tank structure  20  incorporated into a consolidate storage, wherein: 
     The tool box  10  comprises a pair of symmetrically arranged left half casing  11 L a right half casing  11 R and an upright panel  12 . The storage space  111  contained in the left and right casings  11 L and  11 R is molded in diverse shapes for storing assorted tools (which is a general feature, so it not presented in the figures.) The half casings  11 L and  11 R provide a 90° bent side panel  112 . One of the side panels  112  outfits with two buckles  115  and other side panel  112  with two buckle slots  116 . On the bottom rim of the half casings  11 L and  11 R, there is a set-in slotted rim  113 . Both inner sides of the half casing  11 L and  11 R furnish a hinging joint  114 ; the upright panel  12  has a thin panel  121  on the top to connect to a moveable part  122  and a buckle slot  123 . The upright panel has two hinging joints  124  which are staggered corresponding to the hinging joints  114  on the left and right half casings  11 L and  11 R, and a pivot pin unites the joints together to form reliable hinges among the left half casing  11 L, the partition panel  12  and the right half casing  11 R for easy opening and closing operation. The partition panel  12  further provides slots  125  with the clamps  126  mounted within the slots. 
     The fuel tank  20  is a popular one. The top  21  of the fuel tank  20  yields an handle  211 , an inlet  212  and an outlet  213  with covers. The tank body  22  and the tank top  21  are designed with reduced size. On the periphery of the tank body  22 , there is a flange  23  with three T-shape joint blocks  24  and one buckle block  25  to the top. 
     As shown in the FIGS. 1 through 8, the upright panel  12  is linked together with the left and right half casings  11 L and  11 R by inserting a pivot pin through the joints  114  and  124 . The side panels  112  of the left casing  11 L and the right casing  11 R are in the face to face contact while in the close position and contain a space  22  sufficient enough to receive the fuel tank  20  when incorporated with the upright panel  12 . 
     As shown in FIGS. 7 and 8, when the left and right half casings  11 L and  11 R are opened at a certain angle against the upright panel  12 , the three T-shape joint block  24  will enter three slots  125  on the upright panel  12 . While the T-shape joint blocks  24  move upward, being held firmly in place by the clamp  126  within the slots  125  to prevent the joint blocks  24  from disengagement. Upon completion of union of joint blocks within the slots, the moveable part  122  of the thin panel  121  on the top of the upright panel  12  moves close to the tank body  22 . The slot  123  of the moveable part  22  will accept the buckle bloc  25  on the top of the tank body  22 , the moveable part  122  exercises a pressing force to hold the tank body top  21  in a manner to confine the down slide the fuel tank  20  may take and hold the fuel tank  20  in place on the upright panel  12 . Reversibly, if it is intended to take the fuel tank  20  off for independent use, the moveable part  122  is pushed outward to disengage the buckle block  25  out of the slot  123 , the tank body  22  is allowed to slide down, the T-shape joint blocks  24  leave the clamp  126  in the slot  125 , the fuel tank  20  is thus allowed to be taken transversely off the upright panel  12 . 
     As shown in FIGS. 1,  2 ,  7  and  8 , when the fuel tank  20  is sandwiched in the tool box  10 , two half casings  11 L and  11 R are in the relatively close position, the buckle  115  enters the slot  116  to lock the casings resolutely, the top of the left and right half casings  11 L and  11 R and the upright panel press on the top rim  21  of the fuel tank  20 . The set-in slotted rim  113  of the half casings  11 L and  11 R will receive the crop-up bottom flange  23  on the tank body  22  for interlocking effect, plus the insertion of the T-shape joint block  25  of the tank body  22  into the slot  125  of the upright panel  12 , it is easy for the operator to grasp the handle  211  of the fuel tank  20  and carry along the tool box  10  even with heavy tool load. The tool box  10  is easy to open and close and access to the tool even with the fuel tank sandwiched thereon. 
     Viewing from above statement, it is understood that the combination of a tool box with the fuel tank described in the invention has in reality a simple and practical application. It is able to them together or separated for independent use so as to enhance its value.
