摘要： A driver bit and a header punch for manufacture of screws comprising a screw comprising substantially vertical end wall portions of predetermined depth formed on an end edge portion of a bit fitting groove on a screw head, non-planar bottom portions raised from lower edge portions of the vertical end wall portions toward a center of the screw head, inclined groove portions extending from raised portions of the non-planar bottom portions toward a center of a screw neck, a substantially conical-shaped bottom surface formed on a bottom of the groove, the bit fitting groove being adapted to a driver bit, which has a blade adapted to be fitted into the bit fitting groove and has a lower edge portion of the blade adapted to abut against the non-planar bottom portions. In this manner, groove portions of a cross groove on the screw are improved in construction, whereby it is possible to effectively prevent a driver bit from coming out, prevent breakage of screws caused in the prior art, always achieve an appropriate and rapid screw fastening work even when the cross groove of the screw is broken, and to significantly enhance an efficiency in work.
摘要翻译：用于制造螺钉的螺丝刀头和头冲头，其包括螺钉，所述螺钉包括形成在螺钉头上的钻头装配槽的端部边缘部分上的预定深度的基本上垂直的端壁部分，从下边缘部分凸起的非平面底部垂直端壁部分朝向螺钉头的中心，从非平面底部的凸起部分朝向螺钉颈部的中心延伸的倾斜槽部分，形成在槽的底部上的大致圆锥形的底面，所述钻头配合槽适于驱动钻头，该钻头具有适于装配到所述钻头安装槽中并具有适于抵靠所述非平面底部的所述叶片的下边缘部分的叶片。以这种方式，螺杆上的交叉槽的槽部的结构得到改善，从而可以有效地防止螺丝刀头脱落，防止现有技术中的螺丝破裂，总是实现适当和快速的螺丝紧固即使当螺钉的十字槽断裂时，也能正常工作，并显着提高工作效率。

摘要： An electric rotary tool has a built-in recoilles clutch mechanism adapted for a clutch action, which cuts off engagement between an output shaft and a driven shaft when a load torque of a predetermined value or more acts on the driven shaft (38) coupled with the output shaft (14) of an electric motor. The clutch mechanism is formed with a clutch cam surface, which is provided with a projection (40) for resiliently abutting against and engaging with a cam engagement member (42) supported through a torque adjustment spring (46) to cut off engagement between the output shaft and the driven shaft, and the clutch cam surface and/or the torque adjustment spring are set in such a manner that when a load torque exceeds a predetermined value upon forward rotation of the driven shaft to permit the cam engagement member to disengage from the projection on the clutch cam surface, shock on the cam engagement member and the clutch cam surface is absorbed and eliminated.
摘要翻译：电动旋转工具具有适于离合器作用的内置后撤离合器机构，当预定值或更大的负载扭矩作用在与从动轴（38）连接的从动轴（38）上时，输出轴和从动轴之间的啮合电动机的输出轴（14）。离合器机构形成有离合器凸轮表面，该离合器凸轮表面设置有用于弹性地抵靠并与与扭矩调节弹簧（46）支撑的凸轮接合构件（42）接合的突起，以切断输出轴和从动轴，离合器凸轮表面和/或转矩调节弹簧被设定为当从动轴正转时负载转矩超过预定值，以允许凸轮接合构件从离合器凸轮表面上的突起，凸轮接合构件和离合器凸轮表面的冲击被吸收和消除。
