Floating impact apparatus for electrical nail gun
A floating impact apparatus for an electrical nail gun includes a carrier, an impact unit, and a floating unit. The impact unit includes an impact member, and at least one sliding, wheel disposed pivotally on the impact member. The floating unit includes a guiding rod together with the impact member being connected movably to the carrier, two floating members extending through the carrier to connect with the guiding rod at positions proximate to a first side of the carrier, and at least two resilient members disposed between a second side of the carrier and the floating members for biasing the guiding rod and the impact member to move relative to the carrier to thereby maintain contact between the sliding wheel and the first side of the carrier, so as to promote smooth movement and nail-striking force of the impact member.
1. A floating impact apparatus for a nail gun, said floating impact apparatus comprising:
a carrier having opposite first and second sides;
an impact unit including an impact member movable in a nail-striking direction relative to said carrier as a result of application of a force thereto, and at least one sliding wheel disposed pivotally on said impact member and in sliding contact with said first side of said carrier; and
a floating unit including a guiding rod extending along the nail-striking direction such that said guide rod together with said impact member is movable relative to said carrier, two floating members extending through said carrier to connect with said guiding rod at positions proximate to said first side of said carrier and distal from said second side of said carrier, and at least two resilient members disposed between said carrier and said floating member for biasing said guiding rod and said impact member to move relative to said carrier to thereby maintain contact between said sliding wheels and said first side of said carrier.
2. The floating impact apparatus as claimed in claim 1 , wherein said carrier further has at least one inclined surface, said inclined surface having a low point proximate to said second side of said carrier, and a high point distal from said second side of said carrier.
3. The floating impact apparatus as claimed in claim 2 , wherein said high and low points of said inclined surface are opposite to each other along said nail-striking direction.
4. The floating impact apparatus as claimed in claim 2 , wherein said carrier further has a swing arm having said first and second sides, and two parallel guiding rails disposed fixedly on said first side of said carrier and having said inclined surface, said impact unit including two said sliding wheels each having two wheel surfaces that are in sliding contact with said guiding rails, respectively.
