Illuminating device for tool

An illuminating device for a tool includes a light bulb secured in a housing and one or more batteries. The housing has a damper device for attaching to the tool. A switch is disposed between the battery and the light bulb and the housing has a blade for actuating the switch. The blade includes a projection for engaging with the tool and for allowing the blade to actuate the switch by the tool. The damper device has two openings for engaging with the tool and for allowing the tool to be disengaged from the projection when the tool is engaged in an outer opening.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to an illuminating device, and more 
particularly to an illuminating device for tools. 
2. Description of the Prior Art 
Typical tools, such as wrenches and screw drivers may be used during the 
night or in the dark. However, the workers have to carry another 
illuminating device with one hand for illuminating purposes, such that the 
workers may not easily operate the tools. 
The present invention has arisen to mitigate and/or obviate the 
afore-described disadvantages of the conventional tools. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide an 
illuminating device for engaging onto the tool and for allowing the 
working area to be illuminated. 
In accordance with one aspect of the invention, there is provided an 
illuminating device for a tool comprising a housing, at least one light 
bulb secured in the housing, means for energizing the light bulb, and 
means for attaching the housing to the tool. At least one switch is 
disposed between the energizing means and the light bulb for being 
depressed to energize the light bulb. The housing includes an orifice, the 
actuating means includes a blade extended in the orifice for engaging with 
the switch, the blade includes a projection for engaging with the tool and 
for allowing the blade to actuate the switch when the projection is 
engaged with the tool. 
The attaching means includes a pair of clampers extended from the housing 
and parallel with each other for clamping onto the tool. 
The clampers include a first opening for engaging with tool and for 
allowing the projection to be disengaged from the tool and include a 
second opening for engaging with the tool and for allowing the projection 
to be actuated by the tool. 
The clampers each includes a first depression for forming the first 
opening, and each includes a second depression for forming the second 
opening. 
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, an illuminating 
device in accordance with the present invention is provided for engaging 
onto the tool, such as wrench or screw driver. The illuminating device 
comprises a housing 10 and at least one light bulb 13 secured in the 
housing 10 and preferably extended outward of the housing. The light bulb 
13 may also be engaged in the housing 10. One or more batteries 12 are 
secured in the housing 10. At least one switch 18 is electrically coupled 
between the light bulb 13 and the batteries 12 for allowing the switch 18 
to control the electrical energy from the batteries 12 to the light bulb 
13. The housing 10 includes an orifice 16 and a spring blade 14 extended 
in the orifice 16. The spring blade 14 includes a projection 15 provided 
on the free end portion. The housing 10 includes a pair of clampers 21, 22 
extended outward and parallel to each other for engaging onto the driving 
stem 41 of the tools 40 (FIGS. 3 and 4). 
As best shown in FIGS. 1 and 2, the clampers 21, 22 each includes two 
depressions 211, 212, 221, 222 for solidly engaging with the driving stem 
41 and each includes a cusp 213, 223 formed between the depressions 211, 
212, 221, 222 for allowing the driving stem 41 to be moved and engaged 
between the depressions. The depressions 211, 221 form an outer engaging 
opening 30 for disengaging the projection 15 from the driving stem 41, as 
shown in dotted lines in FIG. 4. The other depressions 212, 222 form an 
inner engaging opening 31 for allowing the driving stem 41 to depress the 
projection 15 and for allowing the spring blade 14 to actuate the switch 
18 and the light bulb 13. 
In operation, as shown in FIG. 4, the light bulb 13 may light the dark area 
for allowing the worker to clearly see the dark area. In addition, the 
worker does not need to hold the illuminating device such that the worker 
may easily operate the tool. 
Accordingly, the illuminating device includes a light bulb for lighting the 
dark area and for allowing the worker to easily see the dark area. 
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.
