Abstract

A nail gun includes a nail gun housing, a nail magazine detachably mounted in the nail gun housing and defining with the nail gun housing a nail crown receiving space and first, second and third nail leg receiving spaces, and a nail pusher for pushing a nail to a nailing position in the nail magazine, the nail pusher having a top portion positioned in the nail crown receiving space and first, second and third push portions respectively downwardly extended from two lateral sides and a second side of the top portion and respectively inserted into the first, second and third nail leg receiving spaces. Thus, a large contact surface area of the nail pusher can be abutted against the leg(s) of one of various types of nails to keep the nail accurately in the nailing position, avoiding tilting or any nailing errors.

Claims

1. A nail gun, comprising:

a nail gun housing;

a nail magazine detachably mounted in said nail gun housing, said nail magazine defining with said nail gun housing a nail crown receiving space, and a first nail leg receiving space, a second nail leg receiving space and a third nail leg receiving space in communication with said nail crown receiving space;

wherein said nail magazine comprises a first partition plate, a second partition plate, and a third partition plate;

said first nail leg receiving space is defined between said nail gun housing and said first partition plate;

said second nail leg receiving space is defined between said nail gun housing and said third partition plate;

said third nail leg receiving space is defined between said second partition plate and said third partition plate; and

a nail pusher slidably mounted in said nail magazine for pushing a nail to a nailing position, said nail pusher comprising a top portion positioned in said nail crown receiving space, a first push portion downwardly extended from said top portion and inserted into said first nail leg receiving space, a second push portion downwardly extended from said top portion and inserted into said second nail leg receiving space, and a third push portion downwardly extended from said top portion and inserted into said third nail leg receiving space.

2. The nail gun as claimed in claim 1, wherein said first push portion, said second push portion and said third push portion are formed integral with and respectively downwardly extended from two opposing lateral sides and a front side of said top portion.

3. The nail gun as claimed in claim 1, wherein said first push portion comprises a lateral wall facing toward said nail gun housing, and a plurality of protruding blocks protruded from said lateral wall.

4. The nail gun as claimed in claim 1, wherein said second push portion comprises a lateral wall facing toward said nail gun housing, and a plurality of protruding blocks protruded from said lateral wall.

5. The nail gun as claimed in claim 1, further comprising a pressure plate located on a front side of said nail magazine, said pressure plate comprising a first sliding groove, a second sliding groove and a third sliding groove respectively facing toward said first push portion, said second push portion and said third push portion of said nail pusher.

6. The nail gun as claimed in claim 1, wherein said top portion of said nail pusher are supported on and movable along at least one of said partition plate, said second partition plate and said third partition plate of said nail magazine.

7. The nail gun as claimed in claim 1, wherein said third partition plate of said nail magazine has at least one part thereof disposed below the elevation of the topmost edge of said first partition plate.

8. A nail gun, comprising:

a nail gun housing;

a nail magazine detachably mounted in said nail gun housing, said nail magazine defining with said nail gun housing a nail crown receiving space, and a first nail leg receiving space, a second nail leg receiving space and a third nail leg receiving space in communication with said nail crown receiving space;

a nail pusher slidably mounted in said nail magazine for pushing a nail to a nailing position, said nail pusher comprising a top portion positioned in said nail crown receiving space, a first push portion downwardly extended from said top portion and inserted into said first nail leg receiving space, a second push portion downwardly extended from said top portion and inserted into said second nail leg receiving space, and a third push portion downwardly extended from said top portion and inserted into said third nail leg receiving space;

a pressure plate located on a front side of said nail magazine, said pressure plate comprising a first sliding groove, a second sliding groove and a third sliding groove respectively facing toward said first push portion, said second push portion and said third push portion of said nail pusher; and

a control member movably mounted at said nail gun housing and adapted for moving said pressure plate to adjust the distance between said pressure plate and said nail magazine.

9. The nail gun as claimed in claim 8, wherein said nail magazine comprises a first partition plate, a second partition plate, and a third partition plate;
