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.
