摘要：A device for the driving of a drilling and/or percussion tool provided with aspindle 5 mounted rotatably in the housing 1, the one end of which spindle is suitable for

fastening to the tool piece, the other end being accessible to an oscillating percussionbody 6 movable in the housing 1 by means of a guideway 7, a rotatable driving shaft 3bringing the tool spindle into rotation, a transmission being provided with means for theconversion of the rotary motion of the drive shaft into an oscillatory motion of a drivemember 8, said member being joined to the percussion body through an elastic member26 having a non-linear spring characteristic, wherein the drive member is mounted on thedrive shaft or a shaft coupled therewith, under an angle deviating from 90 degrees to thecentre line thereof, and the elastic member is a plate-like member rotatably connectedto the drive member, and being provided with a coupling means engaging with thepercussion body, whereby the conversion mechanisme can be made simple and small,whilst the frequency of the oscillatory motion can be boosted considerably giving abetter percussion effect on the tool spindle.
