  • Patent number: 6974064
    Abstract: A nail gun includes a body which is provided with an upright slot and a horizontal slot. The upright slot is used to accommodate an explosive array while the horizontal slot is used to disposed a trigger mechanism for discharging nails by the force of the explosive array. The trigger mechanism has a link rod, an actuation rod, a nail firing tube, and a recovery spring. The link rod is triggered by the nail firing tube in motion to bring about the stretching of the recovery spring and the swiveling of the actuation rod such that a retaining hook of the actuation rod is retained in one of a series of retaining slots of the explosive array. The explosive array is forced to move upward by the retaining hook of the actuation rod at such time when the link rod is relieved of the pressure of the nail firing tube.

  • Patent number: 6932260
    Abstract: A nailer includes a gun body, a magazine, a feed plate, a washer barrel, a catch plate, and a locking ring. Thus, the washer is closely positioned between the catch flange of the feed plate and the locking ring, thereby facilitating a user combining the washer with the nail. In addition, the locking ring is tensioned only when the washer passes through the locking ring, so that the locking ring is not maintained at the tightened state constantly, thereby preventing the locking ring from producing fatigue, and thereby enhancing the lifetime of the locking ring. Further, the locking ring is used to stop washers made of plastic or metallic material, thereby enhancing the versatility of the nailer.

  • Patent number: 6918523
    Abstract: A nailer includes a nailer body and a spacer actuator design. The spacer actuator design has a container tube and a flexible propelling unit. A liftable cover is screwed into the top of a container tube. In the case of a closing state of the cover, the hollow trough cover can be connected to the open-top hollow tube of the container tube. A L-shape guide trough is mounted at one side wall of the hollow trough and a wedge groove is placed at the end of L-shape guide trough, where a vertical guide trough is provided at one side wall of the container tube's hollow tube. In the case of a closing state of the cover, the top end of the vertical guide trough will be connected to L-shape guide trough. A propelling unit includes a propelling block, a spring and a control board, of which the spring is mounted between the control board and inner wall of hollow trough to push down the propelling block flexibly. The outer face of the control board is provided with a toggle switch that protrudes from L-shape guide trough.
