Abstract
A power tool holding assembly includes a first direction guiding unit that has a piston-cylinder construction and a linear movement guiding unit that includes a ball spline and is connected via ball bearings to a piston rod of the piston-cylinder construction so as to be freely rotatable. A power tool is mounted onto one end of the spline shaft of the linear movement guiding unit. A space inside the cylinder of the piston-cylinder construction below the piston is connected via a hose coupling and hose to an air compressor that fills the space with compressed air. The air pressure of the compressed air fed into the space is regulated by a pressure regulating valve provided on the hose and so is maintained at a value that keeps the rod stationary.
