    摘要： A motor driven cam and spring impact tool with an improved mounting for the cam. The impact tool includes a driving shaft for rotation relative to the housing. A hammer is positioned in the housing for axial movement with respect to the housing. An annular cam with cam rollers translates the rotational motion of the driving shaft to reciprocating motion of the hammer. A spring urges the hammer in one direction to cause an impact upon each reciprocation. A collar, driven by the shaft, is connected to the cam or selectively to the rollers for rotating one with respect to the other. The non rotating member is attached to the hammer to cause reciprocation. A pair of pins are connected between the cam and selectively the collar or hammer, and spaced apart 180.degree. to allow the cam to tip about the axes of the pins. This equalizes the load imposed by the rollers upon the cam.

    摘要： A power tool comprising: a housing 2; a motor mounted within the housing 2; a tool holder 8 rotatably mounted on the housing 2 for holding a cutting tool; at least one striker 612 mounted in a slideable manner within the housing for generating hammering impulses for a cutting tool, which striker is capable of being reciprocatingly driven by the motor along an axis of travel in a reciprocating cycle, when the motor 18 is activated, via a drive mechanism; characterised in that there at least two strikers 612 which are capable of being reciprocatingly driven along their axes of travel by the motor.
