Abstract
A power tool with hammer mechanism including: a housing; a hollow spindle located in the housing; a hammering unit including a piston reciprocatingly mounted within the spindle; a swashplate drive unit for driving the piston reciprocatingly; the swashplate drive unit including a swashplate finger engaged with the rear end of the piston; the piston including a through opening mostly perpendicular to the longitudinal axis of the piston at its rear end, a free end of the swashplate finger is received directly in the through opening of the piston, at least a part of outer surface of the free end of the finger contacting at least part of inner surface of the through opening during reciprocation of the piston. Such a direct coupling between the swashplate finger and the drive piston minimizes numbers of the parts, reduces complexity of the assembly and the cost.
