TITLE: STRUCTURE OF PENCIL ASSEMBLY ELONGATED BY COMBINATION
BACKGROUND OF THE INVENTION
1. Field of the invention The present invention is related to a structure of pencil assembly whi.ch..can be elongated by combination. And especially is related to a structure of pencil assembly provided with a main shank of the pencil having a fixing annular member thereon, and with a connecting shank for elongating the pencil and having a fixing collar thereon, thereby a user can hold it conveniently, and an object of environmental protection can be 'obtained.
BACKGROUND OF THE INVENTION
1. Field of the invention The present invention is related to a structure of pencil assembly whi.ch..can be elongated by combination. And especially is related to a structure of pencil assembly provided with a main shank of the pencil having a fixing annular member thereon, and with a connecting shank for elongating the pencil and having a fixing collar thereon, thereby a user can hold it conveniently, and an object of environmental protection can be 'obtained.
2. Description of the Prior Art When people use pencils pared with a knife, the pencil will get shorter and shorter in repeated using and paring. And when the remaining pencil is about 1/3 the length, it is discarded for being hard to hold.
In the present days, resource is very limited, wood exploitation is subjected to destroying of woods and human living environment, waste of such resourcE; thereby is necessarily prohibited and improved.
The pencil auxiliary rods sold in the markets (referring to Fig.
1 and 2) nowadays are comprised of a holding rod 10 and a sleeve 20.
The holding rod 10 is provided with a flange 11 on the lower portion thereof, the latter is provided wi th a thread and a plural i ty of clamping pieces 12. The sleeve 20 is provided with a through hole 21 extending therethrough, the through hole 21 allows extending therein the holding rod 10 to fixedly connect therewith by screwing in. When the length of a penci I 30 is inadequate for holding by a user, i t can be inserted among the clamping pieces 12 of the holding rod 10, and then the sleeve 20 is screwed tight to render the clamping pieces 12 to hold the pencil 30. Thereby, the pencil 30 is fixedly connected with the holding rod to solve the problem of inabi 1 i ty of holding to al low cont inuous us ing of the main shank of the pencil.
5 . ~'be conven t i ona t aux i I i a ry rods can make con t i nuous us i ng of penc i 1 s , however, they have the following defects:
1. Cost of production of the auxiliary rods is high; the clamping pieces on the holding rods are subjected to breakage and deformation to render them unable for use.
10 2. The pencils are inserted in the holding rods and locked by screwing in the sleeve, i t is often that a user wri tes wi th overly large force to make contracting of a pencil into a holding rod to result the case of inability or uneasiness of taking out the pencil.

DETAILED DESCRIPTION OF TIC PREFERRED Eh~DIMENT
Referring to Fig. 3 to 5, the present invention is comprised mainly of~a main shank 40 and a connecting shank 50 of the pencil. The main shank 40 is provided with a fixing annular member 41 which is further provided wi th a locking s tub 42 wi th an external thread thereon. A fixing collar Sh' is provided on the connecting shank 50 in cooperation with the fixing annular member 41. The fixing collar 51 is provided at the center thereof with a locking hole 52 for screw locking the locking stub 42. The locking hole 52 is provided therein with an inner thread. The locking stub 42 and the locking hole 52 can be provided in an alternative way, i.e., the locking stub 42 is provided on the fixing collar 51, while the locking hole 52 is provided on the fixing annular member 41.
When the main shank 40 is used and pared repeatedly, and the length thereof is reduced to a degree which is inconvenient for holding, the locking stub 42 provided on the tailing end of the main shank 40 can be screw fixed in the locking hole 52 of the connecting shank 50, so that by adding I:he length on the connecting shank 50, the pencil can be held conveniently, and the main shank 40 can be used continuously to make it be totally used.
The connect ing shank 50 can be used in cooperat ion wi th a main shank 40; and it can be pared for use when the main shank 40 is completely used. Fixing of a main shank 40 with the connecting shank 50 of the present invention is fast and convenient, and can largely reduce waste s of resource. The fixing annular member 41 and the fixing collar 51 can be integrally formed with the main shank 40 and the connecting shank 50 respectively, i.e., the main shank 40 is provided on one end thereof directly with the protruding locking stub 42, and the connecting shank 50 is provided on one end of di rect ly wi th the locking hole 52 connectable l0 with the locking stub 42 (as shown in Fig. 5).
The pencil assemblies of the present invention as shown in Fig. 6 and 7 uses a plurality of main shanks 40 together with an auxiliary rod 60. The ~ux~iliary rod 60 is made of plastic or wood and is provided thereon wi th a locking stub 61. When a main shank 40 is used to a degree 15 which is inconvenient for holding, the locking stub 61 can be screw connected wi th a locking hole 43 provided on the main shank 40 to al low cons inuous use in wri ting. Fig. 8 shows that a plural i ty of main shanks 40 of the present invention can be provided directly on one end of each of them wi th a locking stub 42, while the other end thereof is provided 20 directly with a locking hole 44, so that an almost used-up main shank 40 can be connected with another main shank 40 for use, thereby, the main shanks 40 c:an be continuously used. The pencil assembly of the present invention thereby is structurally simple and can make environmental protection be realized.
25 In conclusion, a main shank of the present invention can be provided wi th a locking stub, whi le a locking hole can be provided on a connecting s shank; or the main shank can be provided wi th a locking hole, whi le the connecting shank can be provided with a locking stub. By mutual connecting of the locking stub and the locking hole, a pencil can be elongated in favor of holding, and the objects of saving resource and rea~.i~ing environmental protection can be achieved. The aforesaid is only for illustrating a preferred embodiment of the present invention.
It will be apparent to those skilled in this art that various modifications or changes can be made to the elements of'the present invention without departing from the spirit, scope and characteristic l0 of 'this invention. Accordingly, all suchmodifications and changes also fall within the scope of the appended claims and are intended to form . part of this invention.
Having thus described the technical structure of my invention with novelty, industrial utility and improvement, therefore, what 1 claim as new and desire to be secured by Letters Patent of the United States are:
