The present invention consists of a main body(8) of this device with an installed clip(7)on it, a driver bit(l) and a wrapping tool(2) being stored in the cavity of the handle of the present invention.
The main body(8), a handle of this device shaped as a circular cylinder is formed with several inner cylinders(3) in which the driver bit(l) and the wrapping tool(2) are stored and the entrance of the main body can be opened and closed alternatively by a screw-type cap(14); a polygonal cavity(l 1) formed for setting the driver bit(l) at the front entrance part of the main body with a ball plunger(lθ); a polygonal socket(9); a wire stripper(13) with several V-type knife edges; a round shaped hole(5) penetrating the main body(8) vertically;
and a polygonal shaped hole(6) bigger than the round shaped hole(5).
At the middle part of the driver bit(l) and the wrapping tool(2), each polygonal shift part(17) is formed as the counterpart of the polygonal cavity(l l) of the main body(8) of this prevent invention.
Among the Figs, No 15, which has ho explanation, is wrapping wire used for setting work of communication line and No 16 is a tip formed at the both ends of the driver bit.
As stated above, since the present invention, a set of hand tool for a communication line setting work, is devised for storing several necessary communication line setting work hand tool components in a small bulk, workers can use said components of this hand tool selectively and interchangeably. Followings are detailed explanation.
In the communication line setting work, such as telephone line setting work etc., the worker use the wrapping socket and the wrapping wire(15). And the necessary hand tools are limited in several kinds, such as the socket(9), the driver bit(l), the wrapping tool(2) and the wire stripper(13) because all the tool components for above said works are a certain standardized goods. The present invention provides all the above said tools in or on the main body(8) of this tool contemporary.(See Fig.3)
That is to say, when the worker don't use all the above-said hand tools, he can store all these tool components into the inner cavities(3) formed in the main body(8) and shut the entrance with the screw-type cap(14). Then the present invention, a set of hand tool, become as small as the main body(8)of this tool. Consequently the user can carry and keep the present invention with ease.
The user can get a necessary hand tool component such as the driver bit(l) or the wrapping tool(2) selectively out of the main body(8) by opening the screw-type cap(14) situated at the rear end part of the main body(8) and use the very hand tool component by inserting into the polygonal cavity(l 1) formed in the front part of the main body(8). The user can carry the communication line setting work without rotating phenomenon in using the driver bit(l) or the wrapping tool(2) since the polygonal shift part(17) is held by the polygonal cavity(l 1).
Then, when the user want to fasten or unfasten a screw he can use the driver bit(l) and when the user want to work of wrapping wire he can use the wrapping tool(2).
As the need arises, the user can select a (+) type tip or a (-) type tip( 16) selectively, and insert the not selected tip(16) part into the polygonal cavity(l l). And there is the ball plunger(lθ) installed in the inner part of the polygonal cavity(l l), and this will press the
inserted driver bit (1) not to be taken off easily.
When the user want to wind the wrapping wire(15) at the around of the pin or unwind it from the pin of the socket(9), he can use the wrapping tool(2) by inserting this into the polygonal cavity (11) with using a end tip selectively as the need arises to the winding or unwinding function.
In case that the user work with the driver bit(l) or the wrapping tool(2) in narrow space, he can insert the driver bit(l) or the wrapping tool(2) selectively into the round shaped hole(5) penetrating the main body(8) of this tool perpendicularly . Then torque will be stronger by using this type combination. Since the polygonal shift part(17) is formed at the shift of the driver bit(l) and the wrapping tool(2) and the diameter of the polygonal shift part(17) is bigger than the diameter of the tip(16). Once the user insert the driver bit(l) or the wrapping tool(2) into the round shaped hole(5), the polygonal shaft part(17) is fitted to the polygonal shaped hole(6) and a raised step formed at the edge of the polygonal shaft part can't penetrate the round shaped hole(5). Consequently, the main body(8) of this invention joined with the driver bit(l) or the wrapping tool(2) in cross angle can get stronger torque than any other conventional hand tool. And the user can work with this in narrow space with ease. (See Fig.3)
The socket(9) formed at the front point of the polygonal cavity(l l) of the main body(8) is formed for fastening or unfastening a bolt or a nut excepting the screw.
For winding the wrapping wire(15) at the around of the pin of wrapping socket with the wrapping tool(2), to begin with, the user have to strip said wrapping-wire's sheath off. The wire stripper(13) is formed for this role. The user insert the wrapping-wire(15) into the wire stripper(13)'s groove which is formed as V-type blade of knife to fit to the standardized wrapping-wire which is used for communication line setting work, and press down said wrapping-wire with his thumb. Then the sheath of the wrapping wire(15) get a scar by said groove. The user pull the main body(8) which is including the wire stripper(13) with pressing down said wrapping-wire with his thumb, then the sheath will be separated from said core wire of said wrapping- wire. Because the size of the groove of the V-type blade of a knife of the wire stripper(13) is standardized previously to the thickness of said wrapping- wire even if the user press down the wrapping-wire with his thumb he can make a scar just on the sheath of said wrapping wire without cutting of a strand of core wire of said wrapping wire. Consequently, the user can strip the sheath of the wrapping wire(15)with only his thumb's pressure. Consequently the present invention has variety of functions and serves as multiple hand tools while utilizing only the small space and the user can carry the prevent invention by pinning the clip(7) stuck on the main body(8) at a working clothes with ease.
