ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an auxiliary handle of an L shape spanner, and especially to an auxiliary handle for receiving a plurality of cylinders and being suitable for being inserted by L shape spanner of different size.
BACKGROUND OF THE INVENTION
The L shape spanner in the prior art has a hexagonal shape, a round shape, a pentagon shape, or other desired shapes. The working end can have a cone shape or hexagon shape, or rectangular shape, or pentagon shape, or cruciform, a line shape, star-like shape or plum flower shapes, etc according to the attached mechanism. The user must prepare various kinds of L shape spanner for matching the requirement. In general, the L shape spanners are disposed disorderly and thus the management is difficult. Especially, for a L shape spanner with a T shape auxiliary handle in which a handle encloses around the force applying end of the L shape spanner, this design cause the operation is more easily and conveniently by the assistance of the handle. However, such prior art L shape spanner with a T shape auxiliary handle is confined that the L shape spanner has many kinds, thus they are assembled one to one, that is, one type of L shape spanner is appended with a specific handle. Therefore, it is necessary a large volume for storing various L shape spanners and are inconvenient in carrying out. Furthermore, the manufacturing cost is high.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide an auxiliary handle of an L shape spanner, wherein only one handle may match with L shape spanner of different size. Thus, any selected L shape spanner may be assembled as an L shape spanner with a T shape auxiliary handle which can be varied easily by assembly and can be operated easily so that the problem of volume occupation and difficult in carrying is resolved.
Another object of the present invention is to provide an auxiliary handle of an L shape spanner, wherein the handle can be formed with indentations for being adhered by fingers. The wall of the cylinder is formed with thread. The wall of the cylinder has nut. Thereby, the extension portion can be compressed so that the long rod of the L shape spanner is tightly clamped so as to achieve the object of securing the L shape spanner.
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.
