Description

鎚擊釘槍Hammer nail gun

本發明有關於一種鎚擊釘槍。The invention relates to a hammer nail gun.

一般的鎚擊式釘槍如專利TW M545676或TW M432507所揭者，包含彼此樞接的外殼與釘匣，外殼內設有撞板，當釘槍被朝待釘物體表面鎚擊，外殼會相對地朝釘匣樞擺，撞板便穿過釘匣而將釘針打出。其中，釘針必需持續被向前推送至撞板相對下方，才能繼續進行出釘。A general hammer nail gun, such as the one disclosed in the patent TW M545676 or TW M432507, includes a shell and a nail magazine that are pivotally connected to each other. The shell is provided with a striker. When the nail gun is hammered toward the surface of the object to be nailed, the shell will face each other. The ground pivots toward the nail box, and the striker passes through the nail box to eject the nail needle. Among them, the nail needle must be continuously pushed forward to the lower side of the striker to continue the nail ejection.

在習知鎚擊式釘槍中，一般係透過一拉伸或壓縮彈簧連接一推釘件，使該推釘件持續保持有推送該釘針之作用。然而，拉伸或壓縮彈簧之特性為變形量越大彈力越大，在裝釘時必需較費力移動該推釘件，且隨著釘針之數量多寡，作用在釘針之作用力不固定，容易產生釘針不穩定、偏斜或翹起，造成卡釘等問題。In the conventional hammer nail gun, a nail pusher is generally connected through a tension or compression spring, so that the nail pusher continuously maintains the function of pushing the nail needle. However, the characteristic of the tension or compression spring is that the greater the deformation, the greater the elastic force. It is necessary to move the nail pusher more effortlessly during nailing, and with the number of nails, the force acting on the nails is not fixed. It is easy to cause the nail needle to be unstable, skewed or warped, causing problems such as stuck nails.

因此，有必要提供一種新穎且具有進步性之鎚擊釘槍，以解決上述之問題。Therefore, it is necessary to provide a novel and progressive hammer nailer to solve the above-mentioned problems.
