PCT No. PCT/CH97/00228 Sec. 371 Date Nov. 30, 1998 Sec. 102(e) Date Nov. 30, 1998 PCT Filed Jun. 6, 1997 PCT Pub. No. WO97/47439 PCT Pub. Date Dec. 18, 1997The hand-held implement has a fixed motor and a hand-held appliance part on which a tool is mounted. The hand-held appliance part is connected to the fixed motor via a driving shaft and a Bowden cable only. The hand-held appliance part has a slide, moving which operates the Bowden cable. The fixed motor is thereby switched on and off and controlled, its output being adjusted according to the amount of draft applied to the Bowden cable. To produce high torque, the hand-held appliance part incorporates a worm gear pair wherein the driving shaft leading to the appliance part drives a worm that engages with a worm wheel, the driven axle of which projects from the housing, enabling a large number of different tools to be mounted on the driven axle. |
