ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is related to an improved nailing gun structure in which the nail magazine is formed with multiple parallel nail channels with different types. A nail-pushing plate is driven by a driving unit to move into any of the nail channels so as to push different rows of nails into a head section of the gun body. The operation of the nailing gun is simple and the different rows of nails can be conveniently replaced.
FIG. 6
shows a conventional nailing gun having a main body
8
and a head section
81
disposed at front end of the main body
8
. A nail magazine
82
is inserted in the head section
81
. A row of nails
83
are received in a nail channel (not shown) of the nail magazine
82
. Two springs
84
are disposed in the nail channel for pushing a nail-pushing plate
85
which pushes the row of nails
83
into the head section
81
for use.
In such conventional nailing gun, the nail magazine
82
has only one nail channel. Therefore, the nail magazine
82
can be loaded with only a row of nails
83
of one kind
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an improved nailing gun structure including a nail magazine formed with multiple parallel nail channels with different types. The nail channels can receive therein multiple rows of different types of nails. The nail magazine is formed with tenons which are transversely movable in corresponding mortises of a frame body, whereby any of the nail channels can be aimed at an inlet of the head section of the gun body. A nail-pushing plate is driven by a driving unit disposed on the frame body to reciprocally move on the frame body. One end of each nail channel is formed with a passage through which the nail-pushing plate can be pushed into the nail channels for pushing different rows of nails in the nail channels into the head section of the gun body. The operation of the nailing gun is simple and the different rows of nails can be conveniently replaced.
The present invention can be best understood through the following description and accompanying drawings wherein:
