Abstract
A driving unit for an electric nail gun includes a pushing block. The pushing block is movable relative to a supporting bracket of the electric nail gun along an axis, and has an inclined surface abutting against an end of a swing arm. Movement of the pushing block results in pivoting movement of the swing arm between a first position, and a second position farther away from a flywheel than the first position. The inclined surface has a slope between 0.087 and 0.7, so as to lock effectively the swing arm at the first position to thereby increase the nail-striking force of an impact member.
Claims6
A driving unit adapted for en electric nail gun, the electric nail gun including a supporting bracket, a flywheel disposed pivotally on the supporting bracket, a swing arm pivotable relative to the supporting bracket between a first position and a second position farther away from the flywheel than the first position, and an impact member pivotable with the swing arm relative to the supporting bracket to contact the flywheel to thereby be driven for performing a nail-striking operation, said driving unit comprising a pushing block adapted to be movable relative to the supporting bracket along an axis and having an inclined surface adapted to abut against an end of the swing arm, said inclined surface having a slope between 0.087 and 0.7, movement of said pushing block relative to the supporting bracket resulting in pivoting movement of the swing arm between the first and second positions.
