The present invention relates to a nail positioning device which position the nail in the path of the nose assembly of a nailer so as to be correctly pushed by the pushing rod.
The conventional nose assemblies for nailers includes two different types, one of which includes a circular or D-shaped path which is cooperated with nails with circular head or D-shaped head. The nails are connected to each other by plastic-made or paper-made connection pieces. The other type of the nose assembly includes a flat path which is cooperated with headless nails or I-shaped head nails. The nails are connected to each other by glue so that the shanks of nails are closely connected to each other. The headless or I-shaped nails are pushed by a flat section of a pushing plate in the magazine so that the long nails can easily positioned in the path and ready to shoot. However, when using short nails, the flat section cannot firmly position the nail in the path so that the other section that has an inclined surface of the pushing plate is used to position the nail in the path. This often makes the short nail orients an angle in the path so that the short nail cannot be ejected out from the nose assembly as desired. Sometimes the last short nail drops from the path because it is not well positioned by the pushing plate.
The present invention intends to provide a nail positioning device that uses a magnet which is located at a proper position of the path so as to attract the nail to ensure that the nail is positioned as expected in the path of the nose assembly.
The present invention relates to a nose assembly of a nailer and the nose assembly is connected to the barrel and comprises a mounting member a base unit. The mounting member is fixed to the base unit and a magazine is connected to the base unit. A path is defined between the mounting member and the base unit so as to receive nails therein. A slot is defined through the base unit and communicates with the path and the magazine. A recess is defined in the mounting member and a magnet is received in the recess so as to attract a nail in the path.
The primary object of the present invention is to provide a nose assembly of a nailer wherein a magnet is connected to the mounting member so as to position the nail of different lengths in the path.
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, a preferred embodiment in accordance with the present invention.
Referring to
It is noted that the magnet 5 can be any known assembly or arrange that attracts the nail 6. The specific position of the magnet 5 ensures that a shank 60 of a short nail 6 is attracted as shown in
While we have shown and described the embodiment 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.
