BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a handle, and more particularly to a tool 
handle assembly. 
2. Description of the Prior Art 
Typical tool handles, particularly the ratchet screw driver handles 
comprise a cylindrical body for engaging with the hand of the user. 
However, the ratchet screw driver handles comprise a number of elements 
that are required to be assembled together by other tools. In addition, 
the tool handle normally includes a cylindrical shape. The hand of the 
user may feel hurt when using such a tool handle. 
The present invention has arisen to mitigate and/or obviate the 
afore-described disadvantages of the conventional tool handles. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a tool handle 
assembly which may be easily assembled without additional tools. 
The other objective of the present invention is to provide a tool handle 
assembly which may allow the user to grasp the tool handle comfortably. 
In accordance with one aspect of the invention, there is provided a tool 
handle assembly comprising a barrel including a bore and including a front 
portion and including a rear portion, a cap including a hole formed 
therein, a body including a front portion having a tube extended forward 
and extended through the bore of the barrel, the body including a rear 
portion having a protrusion formed thereon for engaging in the hole of the 
cap, and means for securing the barrel to the body and for allowing the 
barrel and the body and the cap to be assembled together without 
additional tool. 
The barrel includes an annular shoulder and a notch formed in the rear 
portion, the body includes an annular bulge formed in the front portion 
for engaging with the annular shoulder of the barrel and includes a key 
for engaging with the notch of the barrel and for preventing the barrel 
from rotating relative to the body. 
The cap includes a pair of lumps formed therein, the protrusion of the body 
includes two depressions for engaging with the lumps of the cap and for 
allowing the cap to be solidly secured to the body. 
The body includes a curved upper portion for engaging with a palm of a user 
and includes a curved bottom portion for engaging with fingers of the 
user, and includes a recess for engaging with a ring finger of the user. 
The body includes a chamber formed therein and includes two pairs of 
channels formed therein, the body further includes two partitions secured 
in the channels, a stem rotatably engaged in the partitions, at least one 
gear secured on the stem and located between the partitions, a pair of 
pawls engaged in the body for engaging with the gear, and a knob having an 
actuator for engaging with the pawls for controlling an engagement of the 
pawls with the gear. 
Further objectives and advantages of the present invention will become 
apparent from a careful reading of a detailed description provided 
hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, and initially to FIGS. 1 and 2, a tool handle 
assembly in accordance with the present invention comprises a barrel 20 
including a bore 21 and including a rear portion having an annular 
shoulder 22 and having a notch 23 formed therein. The barrel 20 includes a 
number of annular grooves 304 for facilitating the grasp of the tool 
handle assembly. The barrel 20 includes one or more openings 24 formed 
therein for engaging with tool bits 80. 
A body 30 includes two members 50, 60 secured together by projections 51 
and slots 61. The body 30 includes a tube 38 extended forward for engaging 
through the bore 21 of the barrel 20. The tube 38 includes an annular rib 
35 formed in the front portion for engaging with the barrel 20 by such as 
force-fitted engagement and for rotatably securing the barrel 20 on the 
tube 38. The body 30 includes an annular bulge 33 for engaging with the 
annular shoulder 22 of the barrel 20 and includes a key 34 for engaging 
with the notch 23 of the barrel 20 by such as force-fitted engagement and 
for preventing the barrel 20 from rotating relative to the body 30. The 
body 30 includes a protrusion 36 formed in the rear portion for engaging 
with the hole 41 of a cap 40 which includes two lumps 42 for engaging with 
the corresponding depressions 37 of the protrusion 36 by such as 
force-fitted engagement and for allowing the cap 40 to be secured to the 
protrusion 36 of the body 30. The barrel 20 and the members 50, 60 of the 
body 30 and the cap 40 may thus be assembled together without additional 
tools. 
The body 30 includes a chamber 31 formed therein and includes two pairs of 
channels 32 formed therein for engaging with two partitions 73. A stem 74 
is rotatably engaged in the partitions 73 and includes one or more gears 
75 secured thereon. A pair of typical pawls 761, 762 are engaged in the 
body 30 for engaging with the gears 75 and for allowing the stem 74 to be 
moved in a ratchet way, i.e., the stem 74 may move in an active or a 
reverse direction or in both directions. A knob 71 is rotatably secured to 
the partitions 73 and includes an actuator 72 for engaging with the pawls 
761, 762 and for controlling the engagement of the pawls 761, 762 with the 
gears 75. The knob 71 is engaged in an orifice 306 of the body 30 for 
allowing the knob 71 to be operated by the user. 
Referring next to FIGS. 3, 4 and again to FIG. 1 the tool handle assembly 
includes a curved upper portion 301 for engaging with the palm of the 
user, and includes a curved bottom portion 302 for engaging with the 
fingers of the user and includes a recess 303 for engaging with the ring 
finger such that the tool handle assembly may be grasped by the user 
comfortably. 
Accordingly, the tool handle assembly in accordance with the present 
invention includes a number of members that may be easily assembled 
without additional tools. In addition, the tool handle assembly allows the 
user to grasp the tool handle comfortably. 
Although this invention has been described with a certain degree of 
particularity, it is to be understood that the present disclosure has been 
made by way of example only and that numerous changes in the detailed 
construction and the combination and arrangement of parts may be resorted 
to without departing from the spirit and scope of the invention as 
hereinafter claimed.
