  • Patent number: 8439243
    Abstract: A nailer device includes a housing having a nozzle portion formed in an upper end thereof. A motor and a rotary-linear motion transmission mechanism are arranged in the housing and the rotary-linear transmission mechanism functions to couple an output shaft of the motor to a striking rod disposed in the nozzle portion to thereby move the striking rod in a reciprocating manner. A bias device exerts a force on the striking rod towards the outside of the housing along a longitudinal direction of the striking rod.

  • Patent number: 8348119
    Abstract: A nailer device has a housing containing a motor, a gear box, a transmission mechanism, and a striking rod. The motor, the gear box, and the transmission mechanism cooperate to cause the striking rod to be moved back and forth. The striking rod has a peripheral outer surface and a longitudinal axis and the striking rod and the gear box are connected through a sliding connection structure which allows the striking rod to be moved along its longitudinal axis and which prevents the striking rod from rotating around its longitudinal axis.
