然而,一般的釘匣雖有彈性件等促使釘針有往前移動遞補的傾向,但彈力不宜過大以避免擊發釘針時有出針不良的情形,然而,這也造成了最前端釘針並沒有足夠推抵力量,當撞板向下觸及釘針,釘針的下端有往釘匣後端移動的趨勢,造成釘針歪斜,只要釘針略有歪斜,就有可能無法成功擊發,形成卡釘的狀態,不僅無法完成工作目的,又會損耗釘針與釘槍內部零件。However, although the general nails have elastic members and the like, which tends to move the nails forward, the elastic force should not be too large to avoid the needles being bad when the nails are fired. However, this also causes the nails at the front end. There is not enough pushing force. When the striker touches the nail down, the lower end of the nail has a tendency to move toward the rear end of the nail, causing the nail to be skewed. As long as the nail is slightly skewed, it may not be successfully fired to form a card. The state of the nail not only fails to accomplish the purpose of the work, but also the internal parts of the nail and the nail gun.

本發明之主要目的在於提供一種釘槍,能有效減少卡釘機率,確保擊釘順利。The main object of the present invention is to provide a nail gun which can effectively reduce the rate of the nail and ensure the smoothness of the nail.

The accommodating space is connected to the opening. The front end and the rear end of the body 10 define a length direction. The magazine 11 is disposed on the body. The plurality of staples 20 are accommodated in the 10; the striker 12, 12a, 12b is disposed at the front end of the body 10 and can slide vertically linearly above the opening; the driving portion is disposed on the body 10 and the collision plate 12, 12a, 12b are coupled to drive the striker 12, 12a, 12b to move downward to fire the staple 20. In this embodiment, the drive portion includes a pressure pin 13 located above the body 10; The bottom end 121 of the striker 12, 12a, 12b is concave and has relatively convex opposite ends and a relatively concave intermediate portion. The bottom ends 121 of the strikers 12, 12a, 12b are relatively convex. The end line is approximately parallel to the length direction.

進一步來說,該撞板12、12a、12b的底端121形成一凹槽1211、1211a、1211b,於主要的實施例中,該凹槽1211截面概呈圓弧狀,然而,於其他的實施例中,該凹槽1211a截面概呈梯形,該凹槽1211a的底面寬度小於該凹槽1211a之開口寬度,如圖6所示;在另一實施例中,該凹槽1211b截面概呈三角形,該凹槽1211b的寬度自該凹槽1211b的底部往該凹槽1211b的開口方向漸擴,如圖7所示。其中,該撞板12、12a、12b的底端的凹槽1211、1211a、1211b之最大深度概為該撞板12、12a、12b沿該長度方向的厚度的0.1至1倍,較佳者,該撞板12、12a、12b的底端121的凹槽1211、1211a、1211b之最大深度概為該撞板12、12a、12b沿該長度方向的厚度的0.25至0.5倍。Further, the bottom end 121 of the striker 12, 12a, 12b forms a recess 1211, 1211a, 1211b. In the main embodiment, the recess 1211 has a circular arc shape. However, in other implementations. In the example, the groove 1211a has a trapezoidal cross section, and the bottom surface of the groove 1211a has a width smaller than the opening width of the groove 1211a, as shown in FIG. 6; in another embodiment, the groove 1211b has a triangular cross section. The width of the groove 1211b is gradually expanded from the bottom of the groove 1211b toward the opening of the groove 1211b, as shown in FIG. The maximum depth of the grooves 1211, 1211a, and 1211b at the bottom end of the striker 12, 12a, 12b is 0.1 to 1 times the thickness of the striker 12, 12a, 12b along the length direction. Preferably, the The maximum depth of the grooves 1211, 1211a, 1211b of the bottom end 121 of the striker 12, 12a, 12b is approximately 0.25 to 0.5 times the thickness of the striker 12, 12a, 12b along the length direction.

較佳地,該撞板12、12a、12b的底端121的凹槽1211、1211a、1211b兩端分別往遠離該凹槽1211、1211a、1211b的方向傾斜形成一斜導面1212,有助於分離相鄰的釘針而避免卡釘情況。Preferably, the two ends of the recesses 1211, 1211a, and 1211b of the bottom end 121 of the striker 12, 12a, 12b are inclined away from the recesses 1211, 1211a, and 1211b to form an oblique guide surface 1212, which is helpful. Separate the staples to avoid pinning.
