Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to screw openers, and particularly to a screw opener with an illumination device.
2. Description of Related Art
Referring to
FIG. 1
, a prior art screw opener is illustrated. The screw opener is formed by a combining element, a connecting element and a sleeve. The connecting is installed with a spring and a positioning bead. A shaft is installed between the combining element and the combining element so that the rod of the screw opener may be bent through an angle. However, the structure of the prior art is complex. Not only the cost in manufacturing is high, but also the rod only bends through 90 degrees. This is not practical. Moreover, when the prior art screw opener is rotated through 90 degrees, the handle and the screw head is connected by a third component. The rotating effect is bad and the quality is not uniform. Moreover, the sleeve easy displace when the screw opener screws an object straightly so as to affect the operation of screwing.
Moreover, in a dark environment, when the user screws an object by the screw opener, the user must take a flashlight. However, the operation is inconvenient. It is often that two people are necessary in operation.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a handle having a rod body and a handle. The rod body and the handle are installed with an illuminating device and driving structures. The rod body is formed by a first driving rod and a second driving rod. One end of the rod body is formed with a driving structure which is formed by a teethed half ball. One end of the second driving rod is installed with an opener head and another end of the second driving rod is formed with another driving structure which is a teethed half ball. The driving structure of the first driving rod and the driving structure of the second driving rod are engaged and then they are sleeved by the sleeve; thereby, the rod body can be bent with a predetermined angle and has a function of illumination.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 1 and 2
, the screw opener of the present invention includes a handle
10
, a rod body
20
, a sleeve
30
and an illuminating device
40
.
The handle
10
is a means for being held by a user. The inner side of the handle
10
has a hole
11
at the inner side thereof for being connected to one end of the rod body
20
.
The rod body
20
is formed by a first driving rod
21
and a second driving rod
22
. One end of the first driving rod
21
is inserted into the hole
11
of the handle
10
. Another end of first driving rod
21
is formed with a driving structure
211
which is formed by a teethed half ball.
An inner side of the first driving rod
21
adjacent to the handle
10
is expanded as a receiving space
212
for receiving the illuminating device
40
. A front end of the receiving space
212
is formed with a plurality of via holes
213
so that light can be emitted from the via holes
213
.
One end of the second driving rod
22
may be installed with an opener head and another end of the second driving rod
22
is formed with another driving structure
221
which is a teethed half ball. The driving structure
211
of the first driving rod
21
and the driving structure
221
of the second driving rod
22
are engaged and then they are sleeved by the sleeve
30
. The sleeve
30
is plastic and rigid. The periphery of the sleeve
30
is formed with waveform structure so that the first driving rod
21
and second driving rod
22
are combined firmly. Thereby, the rod body
20
can be bent with a predetermined angle.
The illuminating device
40
is formed by a bulb body
41
, a control key
42
, a battery
43
, conductor
44
, etc. The bulb body
41
is installed in a front end of the receiving space
212
. The battery
43
and the conductor
44
are installed in the inner edge of the receiving space
212
. The control key
42
is installed between the bulb body
41
and the battery
43
. By adjusting the control key
42
, the bulb body
41
light up so that the screw opener has a function of illumination.
Thereby, by above said structure, after the driving structures
211
and
221
at one ends of the first driving rod
21
and one end of the second driving rod
22
are engaged and secured, the rod body
20
can be bent with a predetermined angle. Meanwhile, by the installation of the illuminating device
40
, the use of screw opener is practical.
Moreover, referring to
FIGS. 3 and 4
, in the present invention, the structure of the sleeve
30
may have a rigid L shape. The first driving rod
21
and second driving rod
22
can be engaged to be a rectangular shape. Thereby, the rod body
20
is used to screw a screw located in a dead space. Thus, the present invention is preferred than the prior art.
Moreover, referring to
FIGS. 5
to
7
, another embodiment of the present invention is illustrated. In this embodiment, each of the driving structures
211
and
221
of the first driving rod
21
and second driving rod
22
is formed with stepped structures with convex surface
231
and concave surface
232
. The outer edge of the convex surface
231
is formed with teeth portion
233
. Each receiving hole
234
can receive an elastomer
51
and two ejecting means
52
.
After the convex surface
231
and concave surface
232
are connected by a pivotal shaft
53
, the two ejecting means
52
are ejected by elastomers
51
. In that the two ejecting means
52
are ejected by the two elastomers
51
. Then the ejecting means
52
ejects a respective teeth portion
233
so that the rod body
20
can bend with a predetermined angle. As the rod body
20
is bent, the ejecting means
52
serve to position the rod body
20
in a desired angle.
As described above, when the rod body
20
is desired to drive a screw straightly, a straight-tube sleeve
30
is used to sleeve the first driving rod
21
and second driving rod
22
. The feature of the sleeve
30
is that it can be secured by threaded connection so as to be positioned on the first driving rod
21
and second driving rod
22
(referring to FIG.
6
). When the screw opener is used, the sleeve
30
will not separate from the rod body
20
.
Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
