Abstract
An electric nail gun includes a nail-striking subunit that is adapted to strike a nail, a lifting wheel that is movable to become engageable and not engageable with the nail-striking subunit, a driving member that is rotatable by a motor, and a transmission shaft that is movably connected between the driving member and the lifting wheel, and that is convertible between a first position, where the lifting wheel is engageable with the nail-striking subunit such that rotation of the driving member results in movement of the nail-striking subunit, and a second position, where the lifting wheel is not engageable with the nail-striking subunit such that rotation of the driving member does not result in movement of the nail-striking subunit.
Claims7
An electric nail gun comprising:
- a muzzle unit that surrounds a striking axis and that includes a nail gun seat adapted for loading a nail;
- a cylinder unit that includes
- a striking cylinder connected to said muzzle unit along the striking axis, and
- a nail-striking subunit disposed in said muzzle unit and said striking cylinder, extending along the striking axis, and adapted to be driven by air pressure in said striking cylinder to move along the striking axis for striking the nail;
- a lifting wheel that is mounted to said muzzle unit, and that is rotatable about and movable along a rotational axis, said lifting wheel being movable along the rotational axis between
- a default position, where said lifting wheel is engageable with said nail-striking subunit such that rotation of said lifting wheel results in movement of said nail-striking subunit along the striking axis so as to increase the air pressure in said striking cylinder, and
- a shifted position, where said lifting wheel is not engageable with said nail-striking subunit;
- a casing that is connected to said muzzle unit, and that surrounds the rotational axis;
- a motor unit that is mounted to said casing;
- a driving member that is mounted in said casing, that is connected to and drivable by said motor unit to rotate about the rotational axis, and that has a plurality of spaced-apart first coupling portions arranged about the rotational axis;
- and
- a transmission shaft that is disposed between said driving member and said lifting wheel, that has a plurality of spaced-apart second coupling portions arranged about the rotational axis and respectively and movably engaged with said first coupling portions, and that is co-rotatably and co-movably connected to said lifting wheel such that said transmission shaft is convertible relative to said driving member along the rotational axis between
- a first position, where said lifting wheel is at the default position such that rotation of said driving member results in movement of said nail-striking subunit along the striking axis, and
- a second position, where said lifting wheel is at the shifted position such that rotation of said driving member does not result in movement of said nail-striking subunit along the striking axis.
