| 20080210735 | POWERED STAPLING DEVICE - The present invention relates to an powered stapling device and, more specifically, but not limited to, a powered stapling device for driving staples over a strip of linear material, such as a cable located in an otherwise inaccessible or difficult to reach place. The stapling device includes an actuation mechanism, a handle, a staple ejection mechanism, and a drive arm operable along a primary axis of the stapling device. The actuation mechanism provides energy to the drive arm, which in turn engages the staple ejection mechanism, which in turn drives the staple. At least a portion of the staple engagement mechanism may be positioned at an angle with respect to the primary axis. This configuration of the staple engagement mechanism allows the stapling device to drive the staple at an angle relative to the linear object being stapled, even when the primary axis of stapling device is aligned substantially parallel or substantially perpendicular to the linear object being stapled. | 09-04-2008 |
| 20080272170 | AC electric nail-gun and control method of the same - The present invention relates to an AC electric nail-gun and method thereof. The AC electric nail-gun of the present invention is mainly provided with an integrated circuit (IC), and the IC is connected with a SCR (silicon controlled rectifier) drive circuit such that an actuating magnetic coil is activated by the driving of the SCR drive circuit through a SCR commanded by the IC. By means of the activating, the striker pin of the impact plunger within the actuating magnetic coil beats nail into wood. If an appropriate calculation conducted by the IC according to the reaction force obtained by the striker pin shows that the nail is not firmly beaten into wood, the impact plunger is commanded to allow the striker pin beat nail again before the plunger is brought back to its original position to be activated. A jostle device is provided correspondingly to the impact plunger in such a manner that the return stroke of the impact plunger is limited within a finite distance by mean of the push-forward action of the jostle device when actuated in the repeated nail-impacting cycle of the impact plunger. In this way, the nail can be beaten into wood with multiple stages so as to be nailed firmly into wood by the nail-gun of the present invention which makes the construction easier and more convenient to ensure the quality of construction. Therefore, the commercial availability is further enhanced in the entire operation thereof. | 11-06-2008 |

| 20090101691 | Electric Stapler - A slide frame is mounted on a driver unit that can be vertically reversed on a base frame. A guide pin disposed in the slide frame engages with a concave portion of a cam plate portion formed in the base frame. When a fixation releasing handle of the driver unit is operated, a lever pushes the slide frame to slide the slide frame and the guide pin is deviated from the concave portion to rotate the driver unit. In a state where the driver unit is fixed in a regular posture, since the guide pin is pushing a switch lever, the detection switch is kept turned ON and thus an electric stapler is in an operable state. When the driver unit is rotated, the switch lever is released from the press of the guide pin and the detection switch is turned OFF, thereby cutting off the power. | 04-23-2009 |
