摘要： PROBLEM TO BE SOLVED: To provide a screw driver capable of fastening with high speed and sufficient fastening torque even if a screw has no recess for driving on the screw head.
SOLUTION: The screw driver is equipped with a turbine shaft 12, a vane wheel 13, a body which stores them and rotatably supports the turbine shaft 12, a screw pressing member 14 integrally connected to a plurality of vanes 13b of the vane wheel 13, and a pump connected to an air flow passage 26 formed on the body 11. An air inlet 27 connected to the air flow passage 26 is formed on the body 11 around the vane wheel 13, and a through-hole 23 and an air hole 24 are formed on the screw pressing member 14. The screw head 25a is sucked and fixed to the screw pressing member 14 by a negative pressure through the driving of the pump, and the screw 25 is rotated by the rotation of the vane wheel 13.

摘要： PROBLEM TO BE SOLVED: To provide a cross slot screw easily dimensionally controllable, easily manufacturable, capable of preventing a screwdriver from coming out, and suitable for, particularly, precision types. SOLUTION: In a cross hole 5 formed at the head part 2 of the cross slot screw 1, the bottom face of each of vane engagement grooves forming the cross hole is formed of a part of a shared spherical surface. The outer peripheral side end face of the vane engagement groove is formed in a cylindrical groove outer peripheral end face 8 parallel with the axis of the screw, and the opposite side faces of the vane engagement groove on which both side faces of the each vane of a driver bit 3 engaged with the vane engagement groove touches to form a drive surface are formed parallel with the axis of the screw and parallel with each other. Each vane of the driver bit 3 is formed to be engaged with each vane engagement groove of the cross hole, and its tip is formed in a curved surface with the same radius as a curved surface forming the bottom face of each vane engagement groove of the cross hole. The cross hole can be formed by using an ultra hard pin punch formed in the approximately same shape as the driver bit. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了提供容易尺寸可控，容易制造的十字槽螺钉，能够防止螺丝起子出来，并且特别适用于精密类型。解决方案：在形成在十字槽螺钉1的头部2的十字孔5中，形成交叉孔的每个叶片接合槽的底面由共同的球面的一部分形成。叶片接合槽的外周侧端面形成在与螺杆的轴线平行的圆筒状的槽外周端面8和叶片接合槽的相对的两侧面，与叶片接合槽接合以形成驱动表面的螺丝刀钻头3与螺钉的轴线平行并且彼此平行。驱动器钻头3的每个叶片形成为与交叉孔的每个叶片接合槽接合，并且其顶端形成为具有与形成每个叶片接合槽的底面相同的半径的曲面的曲面十字孔。十字孔可以通过使用形成为与驱动钻头大致相同形状的超硬针冲头形成。版权所有（C）2007，JPO＆INPIT
