ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a nose assembly for a nail ejection gun and the assembly includes a nose piece with two oblique guides, an end of a resilient strip connected to the nose piece and a guide base connected to the other end of the resilient strip. The guide base has two inclined grooves and is located below the nose piece.
BACKGROUND OF THE INVENTION
A conventional nose assembly for a nail ejection gun is shown in FIG.
1
and the nail ejection gun generally includes a gun body
2
and a nail magazine
4
is connected to the gun body
2
. A nose piece
3
is connected to the gun body
2
by bolts
7
extending through holes
30
in the nose piece
3
and fixed to the gun body
2
. A guide channel
31
is defined in a surface of the nose piece
3
. Two oblique guides
311
extend from a lower end of the nose piece
3
and a recess
312
is defined between the two oblique guides
311
. A resilient strip
5
has a first end thereof connected to the nose piece
3
and a second end of the resilient strip
5
is a trapezoid limit piece
51
which is located in the recess
312
. The two oblique guides
311
and the limit piece
51
restrain two legs of a nail to be expanded when penetrating through papers.
In practice, the shape of the limit piece
51
is required to be precise and accurate so that the two legs of nails can be evenly expanded. However, it is difficult to economically manufacture the limit piece with satisfied precision and to install the limit piece at a suitable position in the recess
312
because the second end of the resilient strip
5
is a free end.
The present invention intends to provide a nose assembly for a nail ejection gun wherein the second end of the resilient strip is connected to a guide base having two guide grooves separated by a tapered block. The guide base is pushed by the striking needle when ejecting a nail.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a nose assembly for a nail gun and comprising a nose piece connected to a gun body and the nose piece has a guide channel. A resilient strip has a first end thereof fixedly connected to the nose piece and a second of the resilient strip is connected to a guide base located below the nose piece. The guide base has an extension channel which is in alignment with the guide channel. Two oblique surfaces are respectively defined in two inside defining the extension channel and a block extends from a surface defining the extension channel and has a tapered surface which communicates with the extension channel. Two grooves are defined between the block and the two oblique surfaces.
The object of the present invention is to provide a nose assembly for a nail gun wherein the grooves guiding the two legs of nails are easily to be controlled.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
