Description
IMPROVED STRUCTURE OF SPANNER HANDLE
BACKGROIJ}4D OF THE INVASION
Field of the Invention
The present invention relates to a kind of spanner, and more specifically the improved structure of the spanner handle.
Description of the Prior Art
At present, spanners are applied widely in different occasions. The handle of spanner is of certain length, and common spanners are useless in narrow working places, for operators find it difficult to stretch arms in to operate spanners. The handle may simply be lengthened to overcome this defect and helps to solve the above problems, however, it may also result in larger size of spanners, thus enlarged packing size, higher transportation cost and more space occupied.
Therefore, the inventor develops an improved spanner handle through trial manufactures by combining years of experiences in distribution and research & development of manual tools and components.
SUMMARY OF THE INVENTION
This invention relates to an improved spanner handle, which is lengthened for operations in special locations, and the scope of application is enlarged. /
Another objective of the invention is to provide an improved spanner handle, the lengthened part of which draws near to the handle when not in use, thus no extra packing and space are needed, and transportation of the spanner is easy.
Therefore, this invention offers an improved spanner handle, comprising: A spanner body with a head and a handle, on one end of which is a pivot joint; A lengthening bar with an interconnecting piece on one end, which is used to connect with the pivot joint on the spanner handle. This lengthening bar draws near to or extend with the spanner body with the pivot joint as the axis; A positioning set installed between the spanner body and the lengthening bar and used to position the spanner body and lengthening bar at any specific position.
Referring to the preferred embodiment and description of drawings, the above-mentioned objectives, technique applied, means and other advantages of this invention will become more readily appreciated.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1-7, in an application of this improved spanner handle, the - 3 spanner is composed of a spanner body (1), a lengthening bar (2), and a positioning set (3), wherein: The spanner body (1) has the same structure as common spanners with a header (11) and a handle (12). On one end of the handle (12), there is a pivot joint (13), which is of a biplate structure (131); The engthening bar (2) has on one end an interconnecting piece (21) used to be connected with the biplate structure (131) of the pivot joint (13) on the handle (12). In this application, the interconnecting piece (21), of a uniplate structure, is put between the spanner body (1) and the biplate structure (131) and fastened to the pivot joint with the shaft pin rivet (30); A positioning set (3) is installed between the spanner body (1) and the lengthening bar (2) to locate them on any specific position. In this application, the positioning set (3) is composed of two shaftcups (31), eight steel balls (32), eight elastic cells (33) and two positioning pins (34), where the shaftcups (31) are set on both sides of biplate structure (131) with four locating slots (311) on each side.
Corresponding to the locating slot (31 1), there are push & pull through holes (132) on biplate structure (131) of the pivot joint (13), whose size becomes smaller from outside to inside; In addition, corresponding to through holes (132) on the biplate structure (131), there are also four seizing slot (211) on each side ofthe uniplate structure; eight steel balls (32) are put inside through holes (132) of the biplate structure (131); eight elastic cells (33) are also put into through holes (132) of each biplate structure (131) after steel balls (32), one end of which presses against corresponding steel balls (32), thus a part of steel balls (32) is outside of through holes (132), and held in the seizing slot ( 211) of the uniplate structure, while the other end is positioned in locating slot (311) of the shaftcups (31) (referring to FIG. 3); The positioning pin (34) is between the biplate structure (131) and each shaftcup (31), thus the biplate structure (131) and both shaftcups (31) are connected without being separated from each other (referring to FIG. 4); Described above are the relations of component positions in this invention
and a summary of their structure.
It is noteworthy that there is a notch on handle (12) of the spanner body (1), and a corresponding part is also set on the lengthening bar (2), thus the spanner body (1) and the lengthening bar (2) may merge in one (referring to FIG. 5) without taking up more space.
In addition, referring to FIG. 1, FIG. 5 and FIG. 6, there are sulcal notches (122, 222) on corresponding parts of the spanner body (1) and the lengthening bar (2), thus operators could insert fingers into the sulcal notches to open the spanner, referring to FIG. 6, namely the sketch map of the full open state of the spanner body (1) and the lengthening bar (2).
Referring to FIG. 7, the working environment is narrow and common _s _.
spanners are difficult to operate, while in this invention, hands of operators are not restricted at all by opening the lengthening bar (2) so as to form a right angle with spanner body (1). Operations could be conducted by holding the lengthening bar (2) only, which is really convenient.
It should be mentioned that the lengthening bar (2) is locked when being opened to a scheduled angle, and the locked spanner body (1) and the lengthening bar (2) do not change the locked position before another pulling, therefore, along with the increase of amount of through holes (132) and corresponding seizing slot (211), there are more available angles formed between the lengthening bar (2) and the spanner body (1), and the application range is wider.
Referring to FIG. 8 to FIG. 12, it is another application of the improved spanner handle, and its operation is almost the same as that in the first case, while the difference is that the pivot joint (51) of the spanner body (5) is of a uniplate structure, and the interconnecting piece (61) of the lengthening bar (6) is of a biplate structure. The uniplate structure is set between the biplate structure, and they are connected in one with a shaft pin (60).
Furthermore, the handle (52) of the spanner body (5) is of a T section structure, while the corresponding part of the lengthening bar (6) is of a n -section structure (referring to FIG. 9 and FIG.10), thus the spanner body (5) and the lengthening bar (6) could close as one when approaching each other (referring to FIG.8); when the spanner is being closed, edge of then- section (63) of the _ (, _ lengthening bar (6) could press against lateral margin of T section of handle (52) of the spanner body (5) , thus they form an integrated body; In addition, totally different from the first application, the positioning set of this application is quite simple, which is between the handle (52) of the spanner body (5) and the lengthening bar (6), referring to FIG. 10, and composed of two elastic cells (71) and two steel balls (72). A locating slot (521) could be set on both sides of handle (52) ofthe spanner (5), and elastic cells (71) and steel balls (72) are put into each locating slot (521) in order. A part of steel balls (72) is out of each locating slot (521) under the push of elastic cells (71), and there are seizing slots (62) on both sides of the lengthening bar (6) corresponding to locating slot (521) on handle (52) of spanner body (5). Both seizing slots (62) are used to lock the spanner together with steel balls (72), and the spanner is not to be opened unless external force is exerted.
Referring to FIG. 11 and FIG. 12, the lengthening bar (6) is opened to form different angles with the spanner body (5) in the second application, thus applicable in different occasions.
To sum up, this invention relates to a kind of spanner, which is both used as a common spanner and used in special occasions by lengthening the handle of spanner, and the application range is quite wide; apart from this, the spanner handle is adjusted to be close to the spanner body, thus no extra packaging is added, and no extra transport cost or space are needed. We sincerely hope you could examine and approve this advanced invention and grant the patent thereof.
