The machine (2) has a tool holder (18) driven by an electrical drive motor (6) over a transmission (12) in a rotating manner. A tool holder receives a tool for punching, boring or hammering, another tool for turning boring, and a third tool for screwing. A pneumatic hammer mechanism (20) applies impacts on the former tool inserted in the tool holder. A rechargeable battery (8) is provided for supplying current to the drive motor. The rechargeable battery is accommodated within a housing (4) of the machine.
摘要:
A drill bit is connected to a drill in a simple and rapid manner and used to drill a hole in a backing which may be of wood, plastic or other material in which threads can readily be formed. A threaded insert which has a slightly greater diameter than the hole is then connected to the drill bit in the same manner as the drill and driven by the drill into the hole. The insert forms matching threads in the walls of the hole so that the insert is threadably attached to the backing. A retainer from which a hook is suspended is formed in the insert to permit the hanging of fixtures on the insert.
摘要:
A planing attachment for a rotary hand tool of the type having a generally cylindrical body with an output shaft at a nose end thereof to which a cutting bit can be attached, the attachment being configured at an attaching end to matingly engage the nose end of the hand tool. The attachment includes a housing having an attaching end portion and a planing tool end portion, wherein the attaching end portion is configured to matingly engage the nose end of the rotary hand tool, and a leading plane and a trailing plane are configured wherein one of the planes is disposed on opposite sides of the cutting bit, and wherein the leading plane is elevated relative to the trailing plane by a distance proportional to the depth of cut made by the cutting bit. The attachment further includes a longitudinal cavity disposed between the leading plane and the trailing plane and is configured to receive the cutting bit therein, a cutting bit support disposed at the planing tool end portion of the attachment.
摘要:
Ein Vorsatzgerät (5) wird mittels einer Befestigungsvorrichtung an einer Handwerkzeugmaschine (1) befestigt, die eine Antriebswelle (2) aufweist, die vor einen zu ihr konzentrischen Spannhals (4) vorsteht. Das Vorsatzgerät (5) weist eine mit der Antriebswelle (2) kuppelbare Eingangswelle und eine zur Eingangswelle konzentrische, auf den Spannhals (4) steckbare und mit diesem verspannbare Ringpartie (14) auf. Die Ringpartie (14) weist einen ununterbrochen umlaufenden Ringbereich (15) und einen in axialer Richtung dem Ringbereich (15) benachbarten Spannbereich auf, der mindestens eine in Umfangsrichtung verlaufende Spannzunge (18) bildet. Dem Spannbereich ist ein ihn in Umfangsrichtung umschließendes und dabei die mindestens eine Spannzunge (18) übergreifendes Spannelement (23)zugeordnet, das zwischen einem ungespannten Zustand und einem gespannten Zustand verstellbar ist. Im ungespannten Zustand kann die Ringpartie (14) auf den Spannhals (4) aufgesteckt und von diesem abgezogen werden. Im gespannten Zustand wirkt das Spannelement (23) gegen den Spannbereich der Ringpartie (14) und die mindestens eine Spannzunge (18), sodass die Ringpartie (14) mit dem Spannhals (4) verspannt wird.
