A tool assembly is provided, which includes a primary body and a secondary body having a primary post and a secondary post respectively which are pivotally engaged with each other. An L-shaped primary flange is formed on an inner wall of the primary body and is located adjacent to the primary post, and a primary groove is defined in the primary post and is partially defined in the primary flange. An L-shaped secondary flange is formed on an inner wall of the secondary body and is located adjacent to the secondary post, and a secondary groove is defined in the secondary post and is partially defined in the secondary flange.

FIELD OF THE INVENTION 
The present invention relates to a multifunctional tool assembly. 
BACKGROUND OF THE INVENTION 
A conventional operating tool such as a pair of pliers contains a fixed 
structure and cannot be replaced by tools of an identical function when 
being worn out during long-term utilization, thereby greatly limiting the 
availability of the tool. 
The present invention has arisen to mitigate and/or obviate the 
disadvantage of the conventional tool. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a tool 
assembly with multifunctions. 
In accordance with one aspect of the present invention, there is provided a 
tool assembly comprising a primary body having a first end portion and a 
second end portion. A primary post extends from the first end portion of 
the primary body. An L-shaped primary flange is formed on an inner wall of 
the first end portion of the primary body and is located adjacent to the 
primary post. A primary groove is defined in the primary post and is 
partially defined in the primary flange. 
A secondary body has a first end portion and a second end portion. A 
secondary post extends from the first end portion of the secondary body 
and is pivotally engaged with the primary post. An L-shaped secondary 
flange is formed on an inner wall of the first end portion of the 
secondary body and is located adjacent to the secondary post. A secondary 
groove is defined in the secondary post and is partially defined in the 
secondary flange. 
A pair of pliers includes two plier bodies pivotally engaged with each 
other and each having a shank received in each of the primary and 
secondary grooves and stopped by means of associated primary and secondary 
flanges. 
Further features of the present invention will become apparent from a 
careful reading of the detailed description with reference to the 
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring to the drawings, and initially to FIGS. 2 and 3 with reference to 
FIG. 1, a multifunctional tool assembly in accordance with the present 
invention comprises primary body 10 having a first end portion and a 
second end portion. A primary post 11 extends from the first end portion 
of the primary body 10. An L-shaped primary flange 13 is formed on an 
inner wall of the first end portion of the primary body 10 and is located 
adjacent to the primary post 11. A primary groove 12 (FIG. 3) is defined 
in the primary post 11 and is partially defined in the primary flange 13. 
A secondary body 20 has a first end portion and a second end portion. A 
secondary post 21 extends from the first end portion of the secondary body 
20 and is pivotally engaged with the primary post 11. An L-shaped 
secondary flange 23 is formed on an inner wall of the first end portion of 
the secondary body 20 and is located adjacent to the secondary post 21. A 
secondary groove 22 is defined in the secondary post 21 and is partially 
defined in the secondary flange 23. 
A pair of pliers includes two plier bodies 40 pivotally engaged with each 
other and each having a shank 46 received in each of the primary and 
secondary grooves 12 and 22 and stopped by means of an associated primary 
flange 13 and a secondary flange 23 such that the two shanks 46 of the 
pair of pliers can be pivoted relative to each other by means of a 
relative pivot movement of the two posts 11 and 21. 
Each of the two plier bodies 40 preferably has a head 42 projecting outward 
of the two posts 11 and 21. Preferably, the pair of pliers may comprise 
different forms of plier bodies such as 40B and 40C as shown in phantom 
lines in FIG. 2. 
Referring to FIGS. 2 and 3 with reference to FIGS. 1 and 4, the primary 
post 11 includes two spaced primary ears 14 formed on a free end thereof 
and each having a primary hole 142 defined therein. 
The secondary post 21 includes two spaced secondary ears 24 formed on a 
free end thereof and each juxtaposed to a corresponding one of the two 
primary ears 14. Each of the two secondary ears 24 has a secondary hole 
242 defined therein and aligning with an associated primary hole 142. A 
lug 244 is laterally formed on one of the two secondary ears 24 and is 
received in the associated primary hole 142. 
A retaining axle 30 extends through the primary and secondary holes 142 and 
242 and through a bore 44 defined in the two plier bodies 40 such that the 
two posts 11 and 21 together with the two plier bodies 40 of the pair of 
pliers can be pivoted in concert and can be disengaged from each other 
easily. 
By such an arrangement, the plier bodies 40 of the pair of pliers can be 
removed from the two posts 11 and 21 easily and can be replaced by plier 
bodies 40B or 40C of different forms when being required. 
The retaining axle 30 preferably includes an enlarged head 31. A biasing 
member such as a spring 35 is mounted around the retaining axle 30 and is 
urged between one of the two primary ears 14 and the enlarged head 31. 
Particularly referring to FIGS. 2 and 4, the retaining axle 30 includes a 
slotted free end 32 projecting outwards to one of the two secondary ears 
24. A bore 322 is defined in the slotted free end 32. 
A pivot member 33 is pivotally received in the slotted free end 32 and is 
rested on the associated secondary ear 24. An elongate slot 332 is defined 
in the pivot member 33 and communicates with the bore 322. A pin 34 
extends through the bore 322 and the elongate slot 332 such that the pivot 
member 33 can be pivoted in the slotted free end 32. The pivot member 33 
preferably has an arcuate end 334 received in the slotted free end 32. 
In operation, the pivot member 33 can be urged to project outwards of the 
secondary post 24 by means of the retaining axle 30 as shown in phantom 
lines in FIG. 4 and can then be pivoted relative to the slotted end 32 to 
a position as shown in solid lines so as to abut against the secondary 
post 24. Then, the pivot member 33 can be pushed to move relative to the 
slotted end 32 with the pin 32 sliding in the elongate slot 332, thereby 
securing the pivot member 33 on the slotted end 32. 
Again referring to FIGS. 2 and 3, the primary body 10 has a chamber 18 
defined in the second end portion thereof. A cap 182 is mounted on the 
second end portion of the primary body 10 and has an insert 184 removably 
received in the chamber 18. 
The primary body 10 includes a block 16 formed on the second end portion 
thereof and located beneath the chamber 18. A cylindrical channel 164 is 
defined in a first end of the block 16, and a hexagonal channel 166 is 
defined in a second end of the block 16 and communicates with the 
cylindrical channel 164. 
A tubular sleeve 17 is received in the cylindrical channel 164, and a 
hexagonal rod 174 extends from the tubular sleeve 17 and is securely 
received in the hexagonal channel 166. 
The tubular sleeve 17 has a hexagonal recess 172 defined therein. A 
plurality of driver heads 60 are each removably mounted in the chamber 18 
and each have a hexagonal shank 62 which can be detachably mounted in the 
hexagonal recess 172. 
A clip 19 is pivotally mounted on the block 16 and has two inward-facing 
free ends 192 each mounted in a respective cavity 162 defined in the block 
16. 
The secondary body 20 has an opening 26 defined therein, and a knife 
assembly 70 is adjustably received in the opening 26 and has a knife 76 
slidably received in the opening 26. 
The primary body 10 has a primary recess 15 defined therein, and the 
secondary body 20 has a secondary recess 25 defined therein and aligning 
with the primary recess 15. Two wire strippers 50 are each mounted in a 
corresponding one of the primary and secondary recesses 15 and 25 and each 
have a plurality of notches 52 for stripping wires when the two wire 
strippers 50 are pivoted to be coupled together. 
It should be clear to those skilled in the art that further embodiments of 
the present invention may be made without departing from the scope and 
spirit of the present invention.
