Abstract

FIELD: mechanical engineering. SUBSTANCE: device is mounted on fastener by replaceable standardized head-hood. When flexible member embracing working head with replaceable head-hood mounted in it in the form of double loop acts on handle, it is shifted and due to friction forces it turns the working head for definite angle and displaces thread member. Then the device operates as usual key. Installation of replaceable tared springs changing the effort on working head provides for obtaining the required tared torques during tightening fasteners heads. EFFECT: simpler design. 2 cl, 1 dwg

Изобретение относится к универсальному слесарному ручному инструменту и может быть использовано в любых отраслях промышленности при проведении монтажных работ. Устройство устанавливается сменной стандартизированной головкой-насадкой на крепежный элемент. При воздействии на рукоятку гибкий элемент, охватывающий рабочую головку с установленной в ней сменной головкой-насадкой двойной петлей, перемещаясь, за счет сил трения поворачивает рабочую головку на определенный угол, страгивает резьбовой элемент и затем устройство работает как обычный ключ. Установка сменных тарированных пружин, изменяющих усилие на рабочей головке, обеспечивает получение необходимых тарированных крутящих моментов при затягивании головок крепежных элементов. 1 з.п. ф-лы, 1 ил.The invention relates to a universal bench tool and can be used in any industry during installation. The device is installed with a replaceable standardized head attachment to the fastener. When the handle is exposed to a flexible element, covering the working head with a double loop installed in it with a replaceable head-nozzle, moving, due to friction forces, rotates the working head by a certain angle, strains the threaded element and then the device works like a regular key. The installation of replaceable calibrated springs that change the force on the working head, provides the necessary calibrated torques when tightening the heads of the fasteners. 1 s.p. f-ly, 1 ill.
