一种用于安装防反转螺钉的螺丝刀头及螺丝刀
摘要：
本发明涉及一种用于安装防反转螺钉的螺丝刀头及螺丝刀，螺丝刀头包括用于向待安装的防反转螺钉头部传递扭矩的施力部；所述施力部的转动径向的外侧设有用于与防反转螺钉头部沿防反转螺钉头部上一字通槽的延伸方向挡止配合的定位部。通过螺丝刀头上设置定位部，定位部设置于施力部的径向外侧，用于与螺钉头部沿螺钉头部上一字通槽的延伸方向挡止配合，保证了在安装防反转螺钉时，螺丝刀头卡槽不滑脱，使螺丝刀头与螺钉的承受力的部分紧固在一起，使螺钉的安装更加稳定方便，提高了安装操作效率。
摘要（英）：

The invention relates to a screwdriver bit for mounting a reverse rotation preventing screw and a screwdriver. The screwdriver bit comprises a force applying part for transferring a torque to the head part of the reverse rotation preventing screw to be mounted; and a positioning part in stop matching with the head part of the reverse rotation preventing screw in the extension direction of a horizontal through groove in the head part of the reverse rotation preventing screw is arranged on the outer side of the rotation radial direction of the force applying part. As the positioning part is arranged on the screwdriver bit, is arranged on the radial outer side of the force applying part, and is in stop matching with the head part of the screw in the extension direction of the horizontal through groove in the head part of the screw, when the reverse rotation preventing screw is mounted, the screwdriver bit is clamped in the groove without slipping, the screwdriver bit is fastened with a force bearing part of the screw, the installation of the screw is more stable and convenient, and the mounting operation efficiency is improved.
