  • Patent number: 12186932
    Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.

  • Patent number: 12036651
    Abstract: A nail drive method applied in an electric nail gun, in which a rotary actuator is driven to generate forward rotational kinetic energy for nailing. The rotary actuator has paired wire bundles and magnetic lines arranged in circumferential directions. The nail drive method comprises boosting a pre-loaded voltage of a battery to generate a peak voltage, and storing the electric charge generated by the peak voltage, and then releasing the peak voltage and its electric charge to the rotary actuator through a nailing signal, so that the wire bundles can generate a current to interact with the magnetic lines to generate a tangential force, so that the magnetic lines can drive the rotor to rotate for a specific angle, and the rotary actuator can directly generate a forward rotational kinetic energy for nailing. Thus, the energy conversion structure installed in the conventional electric nail gun can be omitted.

  • Patent number: 8514560
    Abstract: A rotate-to-retract type storing apparatus including a U-shaped protective casing, a shell body and a storing arrangement. A disk member is protrudes adjacent to an open side at the surface of protecting casing, and a protrusion member is provided at a partial position of the disk member. The shell body defines a receiving cavity and includes an insertion hole at a front end thereof for a second end portion of the storing arrangement to get into the receiving cavity and a retention hole penetrating a bottom surface of the shell body for coupling with the disk member so that the shell body is capable of rotating with respect to the protective casing and directing the coupling slot to rotate with respect to the protrusion member. This defines a moving distance—just enough for a first end portion of the storing arrangement to move between an application position and a retraction position. The result is a minimized size of the storing apparatus.
