Abstract

Изобретение относитс  к механизированным инструментам и может быть использовано в любой отрасли промышленности. Цель изобретени  - повышение производительности. При отвинчивании гайки головку 10 устанавливают с помощью кулачка 11 на меньшей угол наклона рабочей поверхности, что обеспечивает максимальный момент вращени . 3 ил.The invention relates to mechanized tools and can be used in any industry. The purpose of the invention is to increase productivity. When unscrewing the nut, the head 10 is set with the help of the cam 11 to a smaller angle of inclination of the working surface, which ensures maximum torque. 3 il.
