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.
