     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     With reference to  FIGS. 1 to 4 , a first preferred embodiment of a tool box in accordance with the present invention has two bodies  10 , two inner boxes  20 , four positioning devices  30 , two positioning blocks  40 , a connecting unit  50 , and a buckle unit  60 . 
     With reference to  FIGS. 1 and 2 , the structures of the bodies  10  may be same with each other. Each body  10  has a side wall  11 , a body space  12 , a collision-resistant space  13  and two engaging portions  14 . The side wall  11  is annular. The body space  12  is formed in the body  10  and has an opening  121  located at a side of the body  10 . The collision-resistant space  13  is formed in a part of the side wall  11 , such that the part of the side wall  11  provided with the collision-resistant space  13  is hollow. The body spaces  12  of the bodies  10  selectively communicate with each other. The engaging portions  14  are formed on an inner side of the body  10 . The inner boxes  20  are respectively mounted in the bodies  10  and are detachably engaged with the engaging portions  14 . 
     With reference to  FIGS. 3 to 5 , the positioning devices  30  are mounted on a side of one of the inner boxes  20 . Each positioning device  30  has a fixing base  31  and a fixing elastic plate  32 . The fixing base  31  is mounted on the side of said one of the inner boxes  20  and has a combining portion  311 , two hooking portions  312 , two hook spaces  313  and two recesses  314 . The combining portion  311  is combined with the inner box  20 . The hooking portions  312  are bent, are respectively connected with two ends of the combining portion  311 , and are opposite to each other. The hook spaces  313  are respectively formed between the hooking portions  312  and the inner box  20  since the hooking portions  312  are bent. The recesses  314  are respectively formed in two ends of the hooking portions  312 . The fixing elastic plate  32  is detachably mounted on the fixing base  31  and has an inserting portion  321  and two hooking portions  322 . The inserting portion  321  is curved. The hooking portions  322  are hooked, are respectively connected with two ends of the inserting portion  321 , and are respectively engaged with the recesses  314 . 
     With reference to  FIGS. 2, 4 and 5 , the positioning blocks  40  are mounted on the positioning devices  30 . Each positioning block  40  has two fixing recesses  41  and multiple tool recesses  42 . The fixing recesses  41  are formed in a side of the positioning block  40 . The two fixing recesses  41  of one of the positioning blocks  40  are respectively engaged with the inserting portions  321  of two of the positioning devices  30 . The two fixing recesses  41  of the other positioning block  40  are respectively engaged with the inserting portions  321  of the other two of the positioning devices  30 . The tool recesses  42  are formed in a side of the positioning block  40  at a position opposite to the fixing recesses  41 . The tool recesses  42  can be used for holding different tool heads. 
     The connecting unit  50  is connected between the bodies  10 , such that the bodies  10  are connected with each other by the connecting unit  50 . The buckle unit  60  is mounted on sides of the bodies  10  at a position opposite to the connecting unit  50 . The buckle unit  60  is detachably engaged with the bodies  10 . 
     With reference to  FIGS. 3 and 6 , in assembling, the inner boxes  20  are respectively mounted in the bodies  10  and are engaged with the engaging portions  14  to be fixed in the bodies  10 . The fixing elastic plate  32  is hooked on the hooking portions  312  of the combining portion  311  by the hooking portions  322 . Then the fixing elastic plate  32  is slid along the hooking portions  312 . When the hooking portions  322  are slid into the recesses  314 , the hooking portions  322  will be engaged with the recesses  314 , such that the fixing elastic plate  32  can be mounted on the fixing base  31 . Then, the fixing recesses  41  of the positioning block  40  are aligned with the inserting portions  321  of the fixing elastic plate  32 , and then the positioning block  40  is pressed. Therefore, the inserting portions  321  can be inserted into the fixing recesses  41 , and the positioning block  40  can be mounted on the positioning device  30 . 
     For replacement, the original positioning block  40  is first pulled to detach from the positioning device  30 . Then, a new positioning block  40  is mounted on the positioning device  30  according to the afore-motioned processes. Therefore, it is convenient for a user to replace different positioning blocks  40 . 
     From the above description, it is noted that the present invention has the following advantages: 
     1. The positioning block  40  is mounted on the positioning device  30  by the fixing recesses  41  and the inserting portion  321 , such that the positioning block  40  can be detached from the positioning device  30  easily. For replacement, the original positioning block  40  is pulled from the positioning device  30 , and then a new positioning block  40  is mounted. The replacing process is easy for the user. 
     2. The engaging portions  14  can fix the inner boxes  20  in the bodies  10 . The collision-resistant spaces  13  are provided as a buffer space, such that the bodies  10  are not broken easily upon a collision. 
     Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
