    摘要: A hammer drill has a movable tool and a driving element substantially coaxial with the tool. The driving element directly transmits axial impact from the same to the tool without transmission of torque. A tool holder surrounds proximal end portions of the driving element and the tool and transmits torque from the former to the latter without transmission of axial impact. Drive means are provided for selectively imparting torque and/or axial impact to the driving element. The tool holder comprises a sleeve which surrounds the proximal end portions. The sleeve is axially movable relative to the driving element and the tool and, at the same time, are connected with them for joint rotation therewith. An additional sleeve is provided surrounding the sleeve and enabling an operator to hold and to guide the hammer drill.

    摘要: A hammer drill is provided with a clutch whose movable part is firmly connected to an axially displaceable drum which supports a wobbling disc driving a percussive mechanism for striking a work tool. The axially fixed clutch part is rotated by driving motor and is backed-up by a housing of the drill. Retroacting forces from the percussive mechanism are transferred via the drum onto the movable clutch part so that the engagement of the clutch is reinforced at the moment when the compression generated by percussive mechanism is maximum. When pressure applied on work tool is relieved, a separating spring disengages the clutch and braking surfaces on the drum limit its axial displacement and brake the rotation of the wobbling disc.

    摘要: A hammer drill is provided with an accessory that is rotatably supported on the chuck of the drill and has a handle fixed to the support rotatable on the drill chuck. Structure is provided forming a throughgoing passage extending from the tool through the handle to the outer end of the handle and a flexible conduit is connected to this handle at the outer end thereof for drawing gas and particles from the tool through the passage. The structure may surround an intermediate portion of the tool at the radial opening of an axial bore through the tool so that particles and the like can be aspirated directly through the tool. Alternately a telescoping tube is provided connected at its rear end to the passage at the support and at its front end to a cup through whose base the drill passes, so that this cup is pressed against the workpiece during the drilling operation.

    摘要: A dust-intercepting member is so mounted on a hand-held power tool as to contact a structure being acted upon around the tool element of the power tool, by a mounting arrangement which includes two hollow elongated mounting members one of which is received within the other for telescoping relative thereto while being retained against rotation with respect to the other mounting member about the common axis of the mounting members, and a helical compression spring the ends of which are respectively received in the interiors of the mounting members and urge the latter in opposite directions. The other mounting member is attached to an auxiliary hand grip which, in turn, is mounted on a cylindrical extension of the housing by a quick-release clamping arrangement. A setting ring on the inner one of the mounting members determines the depth of penetration of the tool element into the structure. A depth-determining profiled rod is displaceably and arrestably mounted on the auxiliary hand grip. The outer one of the mounting members is connected to the profiled rod when the intercepting arrangement is mounted on the auxiliary hand grip.
