- the stability of the case will increased by the shells and those formed by dividing edges Split level in the neck area - in working position considered - bent down and run the kink serves as a handle.
- the stiffening of the Housing increases by attacking the operator's hand and as a result of the operators while working, which makes the Housing shells virtually intertwined and firmly against each other be tense.
- the driver is designed as a connecting rod with a head that has a projection becomes its unwanted one Avoid turning inside the housing and a special one quiet, low-wear running of the hand tool achieved, with the head in the notch of the longitudinal guide is guided to dampen vibrations.
- the axially parallel limits Arrangement of the driving projection for the eccentric pin with a radial distance to the recess, the rotatability of the driver opposite the eccentric pin and thus reduces friction and wear between the eccentric pin, the driver and the tool. It is advantageous that the recess of the clamping end of the Tool is circular and essentially the same Diameter as the projection of the driver.
- the longitudinal guide is immovable as a separate body Arranged inside the case once the case shells are screwed together.
- the longitudinal guide is supported in the direction of movement of the inserted tool against a front wall from one of the housing shells and is thereby captive and free of play but also easy to replace, held because the longitudinal guide after easy Lift off the housing shells in the front area can be removed from the housing.
- the longitudinal guide is a separate body, she takes the cassette-like over the shaft of the tool bending forces transmitted to the housing and conducts this continues on the housing, so that this only is subjected to low bending and twisting forces and can be carried out in lightweight construction, with rolling elements both ends of the guide slot of the longitudinal guide Wear or, the friction between the longitudinal guide and reduce the tool, because only roll instead of is permitted by sliding friction.
- the tool can be a chisel, scraper, spatula or the like. made of metal, e.g. Tungsten carbide or HSS steel. It is versatile, e.g. to carve, to remove Paint, wallpaper, carpet adhesive, foam backing, needle felt, PVC, also for cleaning work, e.g. Removing dirt, Adhesive and glue, plaster, plaster, filler, putty, Paint and silicone residues as well as mortar and concrete residues Building boards.
