1results about How to "Prevent excessive speed" patented technology

This invention relates to an electric nailing tool, belonging to the field of power tool technology. An electric nailing tool includes a housing with a handle, an energy storage mechanism consisting of a cylinder and a piston housed within the housing, a nailing seat at the front end of the housing with a retractable striking arm forming an striking mechanism, a nailing mechanism consisting of a striking pin extending from the piston to the nailing seat, a lifting mechanism consisting of a motor-driven drive wheel meshing with the striking pin, a nail feeding mechanism mounted on the side of the nailing seat, and a power transmission mechanism consisting of a gearbox and a motor located between the handle and the nail feeding mechanism. Its advantages are: the drive wheel is quickly ejected at the engagement critical point to avoid stress damage to the striking pin teeth; it avoids interference between the excessively high speed of the drive wheel and the lifting teeth, thus improving the overall lifespan of the electric nailing tool.
