ABSTRACT:
BACKGROUND OF THE INVENTION
A conventional power stapler is shown in FIG.
1
and generally includes a body
10
with a barrel
100
extending from the body
10
. A safety device
13
is received in the barrel
100
and is able to actuate a trigger means
11
to a ready-for-shoot status. A handle
101
is integrally connected to the body
10
and has a passage
102
defined therein. A magazine
14
is connected between the handle
101
and the barrel
100
so as to receive nails therein. A fitting of a hose
17
is connected to the handle
101
so that pressurized air is sent into the passage
102
in the handle
101
to eject a nail in the magazine
14
. The body
10
and the handle
101
are made of cast iron so that it is so heavy and is not convenient to be used. When nailing nails into an object, the nose piece is pushed against the object so as to put the trigger means
11
to a ready status. Because the power stapler is heavy in weight and only one point contacts against the object so that it is difficult to nail the object at even distance. Furthermore, the safety device
13
is not adjustable so that the conventional power stapler can only use a fix-sized nails.
The present invention intends to provide a power stapler which has a separated handle made of light material and an adjustable nose piece so as to adjust a distance that a line of the safety device can be moved to touch a trigger means.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a power stapler and comprising a body with a barrel and a trigger means. A handle is connected to the body by bolt and a magazine is connected between the handle and the barrel. A safety device is connected to the barrel and includes a link connected to the trigger means.
The primary object of the present invention is to provide a power stapler which has a handle light in weight. The handle is connected to the body by a connection plate and bolts.
Another object of the present invention is to provide a power stapler which has an end member connected to the handle by a pin and an L-shaped wrench is received in a connection portion extending from the handle.
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.
