Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a nailer, and more particularly
to a positioning structure for a nailer having an adjusting member
which is designed to enable the user to adjust the position of the
nailer arbitrarily, and the adjusting member has an engaging paw
and a press key which are laterally disposed for make the operation
easy for the user.
[0003] 2. Description of the Prior Arts
[0004] Nowadays, nailers have been widely used in different trades.
However, only a skilled user can eject the nail precisely into an
object to be nailed, that means the nailing accuracy of the conventional
nailers replies on the experience of the user. An unskilled user
hardly can make the nail eject into an object precisely, and due
to the heavy weight, the nailer is likely to sway during the nailing
course, the nail is likely to deviate from the nailing position.
Thereby, the conventional nailer is difficult to be controlled.
[0005] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a positioning structure for a nailer capable of adjusting the position
of the nailer arbitrarily. In the rail of magazine is slidably provided
an adjusting member whose lateral side is disposed an engaging paw
against which a spring abuts. The engaging paw is formed in response
to the shape of the cavities in the sidewall of the groove of the
rail. On a side of the engaging paw opposite the spring is disposed
a press key which partially projects out of the adjusting member
so as to be pressed by the user. This adjusting member can enable
the user to adjust the position of the nailer arbitrarily.
[0007] The secondary objective of the present invention is to provide
a positioning structure for a nailer which can make the operation
easy for the user and can be prevented from being mistakenly pressed
by the user. The lateral disposed engaging paw and the press key
can make the operation easy for the user, and the press key is designed
to prevent the nailer from being pressed mistakenly by the user.
[0008] The present invention will become more obvious from the
following description when taken in connection with the accompanying
drawings, which show, for purpose of illustrations only, the preferred
embodiments in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] Referring to FIGS. 1-3, a positioning structure for a nailer
in accordance with the present invention generally comprises the
following components:
[0014] A magazine 10 is installed at the front of the nailer A,
in the front side of the magazine 10 is provided a T-shaped rail
11 which is interiorly defined with groove 12. On a sidewall of
the groove 12 are arranged a plurality of cavities 121.
[0015] An adjusting member 20 comprises a main body 21 and a cover
22. At the bottom surface of the main body 21 are formed two opposite
L-shaped flanges which are to be correspondingly mounted onto the
T-shaped rail 11 of the magazine 10. The main body 21 is formed
with a chamber 212 in which two elongated cavities 213 are formed
and located in the direction of the groove 12. In the chamber 212
is further defined a press hole 214 which faces toward the cavities
121 in the groove 12. On a sidewall of the chamber 212 opposite
the press hole 214 is formed a positioning block 215.
[0016] An engaging paw 30 is slidably disposed in the chamber 212
of the main body 21, at the bottom edge of the engaging paw 30 are
provided two positioning projections 31 which are employed to insert
in the two elongated cavities 213 of the chamber 212. The two positioning
projections 31 are formed in response to the shape of the cavities
121. On a lateral side of the engaging paw 30 is formed a press
key 32 which is confined in the chamber 212 and partially protrudes
out of the press hole 214. The press key 32 is to be pressed by
the user.
[0017] A spring 40 is biased between the positioning block 215
of the adjusting block 20 and the engaging paw 30.
[0018] With reference to FIG. 3, before the user presses the press
key 32, the two positioning projections 31 of the engaging paw 30
is pressed by the spring 40 and engaged in the two elongated cavities
213. Although the two opposite L-shaped flanges 211 of the adjusting
member 20 are slidably mounted onto the rail 11, the adjusting member
20 will still be positioned at a desired position by the engaging
paw 30. The adjusting member 20 is used to abut against the working
surface or the edge of the wall to be nailed, so that the nail can
be precisely driven into the object to be operated.
[0019] With reference to FIG. 4, when the user keeps pressing down
the press key 32, an end of the spring 40 still abuts against the
positioning block 215, and another end of the spring 40 is compressed
by the engaging paw 30. At this moment, the two positioning projections
31 of the engaging paw 30 are pushed back from the two elongated
cavities 213 of the chamber 212 and move into the groove 12 of the
magazine 10, that is to say that the two positioning projections
31 of the engaging paw 30 disengage the cavities 121 on the sidewall
of the groove 12. The adjusting member 20 is now allowed to move
freely along the rail 11 by using the two L-shaped flanges 211,
until the user releases the press key 32, the adjusting member 20
will be positioned by the positioning paw 30 again. Through this
way, the user can easily position the adjusting member 20 at any
position on the rail 10 by using the press key 32.
[0020] In addition, since the press key 32 and the positioning
paw 30 are disposed at lateral side of the adjusting member 20,
this makes the operation easy for the user. Moreover, the press
key 32 can be prevented from being pressed by a mistake during operation,
since it is laterally disposed.
[0021] While we have shown and described various embodiments in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention. |
