Abstract
A working stand for collarless electrical home worker machines, which machines have at the end of their drive shaft a threaded section for screwing on or attachment of a drill chuck. A machine holder is moveable up and down a vertical polygon guide column and can be fixed in position at whatever desired height. The guide column has a toothing, in which there engages a gear which is driveable by means of a hand crank, the gear being mounted in the machine holder. The machine holder has a pair of adjustable clamping jaws embracing the polygon guide column. In the machine holder a vertical shaft is rotatably mounted, which shaft on the upper end has an axially interior threaded section for reception of the drive shaft of the machine and on the lower end, which end projects from the machine holder, has a threaded section for the screw-on attachment of the drill chuck.
