Abstract (en)
[origin: EP0589267A2] In a powered hand tool with bail-spring (bowed-spring) percussive mechanism, the coupling of the percussive mechanism (105) is effected by axial displacement of an eccentric drive member (107) on a shaft (104). During this process, the eccentric (108) slides into a fork (112) coupled to a driver member (115) for the reciprocating drive of the percussive element (124). The axial displacement of the drive member (107) is effected by displacement of a gearwheel (130) connected to the tool spindle (131). <IMAGE>
