Description

The present invention relates to a stapler nailer, and more particularly to a labor-saving stapler nailer.

Conventional nail guns have patents such as US5,505,362, US5,816,470 and US6,789,719. By turning the handle, they turn the connecting bar inside the nailing machine and move the impact plate that slides linearly to the launch waiting position. At this time, the impact plate is a spring or a flake spring. The impact plate is curved and the force is accumulated while moving to the launch waiting position, and when the connecting bar is further swiveled and separated from the impact plate, the impact plate is elastically pressed by the impact plate. , Moves down quickly to launch a nail.

Such nail guns are actually prone to failure. The mechanism for releasing the impact plate of such a nail gun is achieved by the automatic separation of the swiveling connecting bar and the linearly moving impact plate, so that the connecting bar has been used and worn for a long time. Later, the timing to release the impact plate becomes earlier, and the accumulation of the force of the flake spring becomes insufficient, so it may not be possible to reliably launch the nail. In addition, if the position of the impact plate and the connecting bar changes even a little due to an error during production or the impact of an external force, the timing of releasing the impact plate may change, and the impact plate may not be released. be.

On the other hand, such a nail gun holds the position after the impact plate is launched when not in use, and is in continuous contact with the nail in the nail gun, so that the nail is driven by the connecting bar and then moved. If you do not move forward and place it in the correct position, you will not be able to launch the nail smoothly. When used quickly and continuously by the user, the impact plate tends to impact downwards before moving the nail to the correct position, causing the nail to be abnormally pressed to block the outlet and be easily damaged.
