Abstract

A nail gun includes a gun body, a safety unit, a detecting member and a blocking unit. The gunbody defines a firing path and a guiding groove therein. The safety unit is movable relative to the gun body. The detecting member and the blocking unit are disposed on the firing seat. When both the firing path and the guiding groove receive nail therein, the detecting member abuts against the nail in the guiding groove and is spaced apart from the nail in the firing path, and the blocking unit permits the movement of the safety member relative to the gun body. When the firing path and the guiding groove are empty, the detecting member is inserted into the firing path, and the blocking unit hinders the movement of the safety member relative to the gun body.

First claim

What is claimed is:

1 . A nail gun adapted for sequentially firing a plurality of nails, each of the nails having a head and a body, said nail gun comprising:
a gun body including a firing seat that defines a firing path and a guiding groove therein, said guiding groove being in spatial communication with said firing path; a magazine adapted for receiving the nails therein, and connected to the firing seat such that the nails can be moved from the guiding groove into the firing path one at a time; a safety unit disposed on said gun body, and movable relative to said firing seat in a moving direction between a normal position where firing operation of said nail gun is not permitted, and a depressed position where the firing operation of said nail gun is permitted; a detecting member disposed on said firing seat, and having a detecting portion that is pivotable relative to said firing seat and that is resiliently biased into said firing path such that : when said firing path receives one of the nails therein and when said guiding groove receives at least one of the nails therein, said detecting portion is at a multi-nail position where said detecting portion is adapted to abut against the body of the nail received in said guiding groove, and is adapted to be spaced apart from the nail received in said firing path; when said firing path receives one of the nails therein and when said guiding groove is empty, said detecting portion is at a single-nail position where said detecting portion is adapted to abut against the head of the nail received in said firing path; and when said firing path and said guiding groove are empty, said detecting portion is at a null position where said detecting portion is inserted into said firing path; a blocking unit pivoted to said firing seat, and having a blocking portion and an urging portion, said urging portion being in contact with said detecting portion of said detecting member such that, when said detecting portion of said detecting member is at the multi-nail position or at the single nail position, said blocking portion is misaligned from said safety unit in the moving direction so as to permit said safety unit to move to the depressed position, and when said detecting portion of said detecting member is at the null position, said blocking portion is aligned with said safety unit in the moving direction so as to prevent said safety unit from moving to the depressed position; and a resilient member disposed between said blocking unit and said firing seat, and resiliently biasing said urging portion of said blocking unit to abut against said detecting portion of said detecting member.

2 . The nail gun as claimed in claim 1 , wherein said firing seat includes a seat body, and a cap member that is connected to said seat body and that cooperates with said seat body to define said firing path and said guiding groove therebetween, said detecting member having a pivoted portion that is pivoted to said cap member, said detecting portion of said detecting member being connected to said pivoted portion.

3 . The nail gun as claimed in claim 1 , wherein said detecting portion of said detecting member has a first detecting surface that faces and corresponds in position to said guiding groove and that is adapted for abutting against the nail received in said guiding groove, and a second detecting surface that faces and corresponds in position to said firing path and that is offset from said first detecting surface and that is adapted for abutting against the nail received in said firing path.

4 . The nail gun as claimed in claim 3 , further comprising a magnetic member that is mounted in said firing seat and that is adapted for magnetically attracting the head of the nail received in said firing path.

5 . The nail gun as claimed in claim 1 , wherein said blocking unit includes a linking member that has said urging port ion, and a blocking member that is in slidable contact with said linking member and that has said blocking portion.

6 . The nail gun as claimed in claim 5 , wherein one of said linking member and said blocking member has an inclined surface that has an abutment surface portion, the other one of said linking member and said blocking member having an inclined surface that is in slidable contact with said inclined surface of the one of said linking member and said blocking member, and a driving block that is formed on said inclined surface thereof, such that during the movement of said detecting portion from the single-nail position to the null position, said resilient member resiliently rotates said linking member to maintain the contact between said urging portion and said detecting port ion, so that said driving block and said abutment surface portion are pushed against each other to rotate said blocking member to align said blocking portion with said safety unit in the moving direction.

7 . The nail gun as claimed in claim 6 , wherein said resilient member is configured as a torsion spring, and has a first end section that abuts against said linking member, and a second end section that abuts against said gun body.
