1. Field of the Invention
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.
2. Description of the Prior Arts
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.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
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.
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.
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.
Referring to
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.
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.
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.
A spring 40 is biased between the positioning block 215 of the adjusting block 20 and the engaging paw 30.
With reference to
With reference to
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.
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.
