Abstract
Изобретение откоситс к устройствам, предназначенным дл производства сверлильных работ в камне и бетоне, вчастности к ручным электроинструментам дл виброударного сверлени . Целью изобретени вл етс повышение производительности процесса сверлени за счет задани инструменту сложного движени в процессе свер- лени . Ударно-сверлильна насадка содержит корпус 1, втулку 4, держатель 7 инструмента, вибратор и пружину 11 Держатель инструмента установлен на втулке 4 с возможностью осевого перемещени и св зан с ней посредством штифта 9, который установлен в наклонных пазах 10 втулки 4 и за с.чет наклонных пазоо проворачиваетс относительно нее 3 илThe invention relates to devices intended for drilling in stone and concrete, in particular to hand-held power tools for hammer drilling. The aim of the invention is to increase the productivity of the drilling process by giving the tool complex movement during the drilling process. The hammer drill contains a housing 1, a sleeve 4, a tool holder 7, a vibrator and a spring 11. The tool holder is mounted on the sleeve 4 with axial movement and is connected with it via a pin 9, which is installed in the inclined grooves 10 of the sleeve 4 and after. even inclined pazoo rotates about it 3 il
