Safety member and muzzle of nail gun having the same
A safety member is adapted for use in a muzzle of a nail gun. The muzzle defines a nail passage that is for passage of a nail, and a gap that spatially communicates with the nail passage. The safety member is slidable in a nail striking direction of the nail, and includes a slider adapted to be disposed in the gap, and having a flat surface, a platform and an abutment end. The flat surface is adapted to face the plate member. The platform protrudes from the flat surface toward the plate member and cooperates with the plate member to define a nail ejection opening therebetween. The abutment end extends from the platform and extends beyond the nail ejection opening for contact with an object to be fastened.
1. A muzzle of a nail gun, the nail gun being operable to actuate a nail striking pin of the nail gun to switch to a nail striking state to strike a nail, said muzzle comprising:
a plate member;
a barrel member cooperating with a bottom surface of said plate member to define a nail passage which is adapted for passage of the nail; and
a safety member including a slider that is disposed between said plate member and said barrel member and that is slidable in a nail striking direction of the nail, said slider having a flat surface facing said bottom surface of said plate member, and a platform protruding from said flat surface toward said bottom surface of said plate member;
wherein said platform and said plate member cooperatively define a nail ejection opening therebetween; and
wherein said slider of said safety member further has an abutment end that extends from said platform and that extends beyond said nail ejection opening for contact with an object to be fastened.
2. The muzzle as claimed in claim 1 , wherein said platform of said slider of said safety member extends in the nail striking direction.
3. The muzzle as claimed in claim 1 , wherein said barrel member has:
a nail receiving surface which is formed with a nail receiving opening, which is proximate to said plate member, and which cooperates with said plate member to define said nail passage, and
a support surface which is further away from said plate member than said nail receiving surface, and which cooperates with said plate member to define a gap adapted for said slider of said safety member to slide therein.
4. The muzzle as claimed in claim 3 , wherein a maximum width of said platform is smaller than a maximum width of the nail striking pin and is greater than a maximum width of said nail receiving opening with respect to a direction perpendicular to the nail striking direction, so as to ensure the nail to move smoothly over said platform in the nail striking direction during a nail striking operation.
5. The muzzle as claimed in claim 1 , wherein said slider of said safety member further has an inclined surface that has an end connected to said platform and an opposite end connected to said flat surface, and that is adapted for guiding movement of the nail received in said nail passage during a nail striking operation.
6. The muzzle as claimed in claim 1 , wherein said plate member includes a plate body, and a lock piece that is pivotally connected to said plate body and that removably engages said barrel member for maintaining relative position between said plate member with said barrel member.
7. The muzzle as claimed in claim 6 , wherein said plate body of said plate member has two notches respectively formed in opposite sides thereof, said barrel member having two hook portions that respectively extend through said notches and that cooperatively and removably hook said lock piece of said plate member so as to secure said plate member with respect to said barrel member.
